CompTIA A+ Core 1 Practice Test Flashcards
What causes a mobile device battery to swell?
A swollen battery indicates a problem with the battery’s charging circuit, which is supposed to prevent overcharging.
Improper charging routine
An improper charging routine will reduce the usable life of a battery. A Li-ion battery should not be allowed to fully discharge regularly or be kept persistently at 100% charge.
Old battery
As batteries age, they will not hold a proper charge. Symptoms can be that the device will not switch on or only remains on for a few seconds.
Underpowered adapter
Charging ports can be damaged by improper insertion and removal of the connectors. Signs of this are no charging or intermittent charging.
A technician notices that the printer’s output was not expected and needs to check the printer’s control panel to investigate the problem. What does the technician need to check?
Calibration is how the printer determines the appropriate print density or color balance. Most printers calibrate themselves automatically.
Maintenance kit
A maintenance kit is a replacement feed roller, transfer roller, and fuser unit. The printer’s internal copy count of the number of printed pages guides the replacement kit.
Toner
Toner is composed of a fine compound of dyestuff and wax or plastic particles. The toner carries the same negative charge polarity as the drum.
Developer roller
The developer roller is very close to the photosensitive drum. The toner is fed evenly onto a magnetized developed roller from a hopper.
This protocol transfers email messages across a network and uses TCP port 25.
Simple Mail Transfer Protocol (SMTP) transfers email messages across a network and uses TCP port 25.
FTP
File Transfer Protocol (FTP) makes files available for download across a network. It utilizes two ports. TCP Port 21 establishes the connection between two computers (control connection), and TCP port 20 is the port the file(s) are transferred across (data connection).
Telnet
Telnet makes an unsecured connection to the command-line interface of a remote server and uses TCP port 23.
SSH
Secure Shell (SSH) makes a secure connection to the command-line interface of a remote server and uses TCP port 22.
What problem does a screensaver help prevent?
When the same static image displays for an extended period, it can damage the monitor’s picture elements, causing a ghost image to “burn” permanently onto the display. An animated screensaver can help prevent this problem.
Fuzzy image
If the output resolution does not match the display device’s native resolution, then the image will appear fuzzy.
Dim image
Incorrect settings or a failed backlight can cause a dim image. Adjusting the brightness and contrast of a display can help fix a dim image.
Stuck pixels
A flat-panel monitor defect may cause individual pixels to be “stuck” or “dead.” If a digital display panel has stuck pixels, and the panel is not replaceable under warranty, then software utilities are available to reactivate pixels.
An automobile allows for connecting a smartphone or tablet for entertainment and audio purposes. Pairing the two occurs with which technology?
A Bluetooth wireless radio creates a short-range personal area network (PAN) to share data with a PC, connect to a printer, and even connect to automobiles. The connection occurs through what is known as pairing.
NFC
Many mobile devices have near-field communication (NFC) chips built in. NFC allows for very short-range data transmission (up to about 20 cm/8 in.) to activate a receiver chip in a contactless reader.
Hotspot
A smartphone or tablet can be configured as a personal hotspot to share its cellular data connection with other computer devices.
Wi-Fi
Every laptop, smartphone, and tablet supports a Wi-Fi radio. While some automobiles also offer built-in Wi-Fi, this technology is not used to pair two devices.
What hardware on a client’s computer allows a device and printer to connect over a network?
A print server is a hardware and firmware that allows client computers to connect directly over the network without going via a server computer.
Printer share
The print share model describes how multiple client devices access the printer. Ordinary users can connect to a network printer if the print server administrator grants permission to use it.
Secured prints
Secured print is held on the print device until it authenticates directly with the print devices. This mitigates the risk of intercepting confidential information from the output tray before the user has had time to collect it.
Audit log
An audit log can identify printed documents that have gone missing or identify the unauthorized release of information.
A user is trying to connect a gaming console to a television. What type of connector should the user utilize?
A high-definition multimedia interface (HDMI) is the most widely used video interface. HDMI supports both video and audio. The user would utilize this because it is ubiquitous in consumer electronics.
USB 3.0
USB 3.0 has new versions of Type A, Type B, and Type B Micro connectors with additional signaling and wires.
Adapter
An adapter cable has connectors for two different cable types at the end. An active adapter uses circuitry to convert the signal.
Lightning port
A Lightning port is found only on Apple’s mobile devices. The Lightning connector is reversible. The user needs a suitable adapter cable to connect such a device as a Lightning-to-USB A or Lightning-to-USB C.
An IT support specialist updated all the information systems in the office last week and the users are complaining that the routinely used applications no longer work. What is most likely the issue breaking the applications?
Legacy software applications and operating systems may not perform well if a user’s system has been upgraded.
Resource requirements
Resource requirements are important to consider and meet when setting up a virtualized system and network for virtualized systems to use. If the system is not designed with resource requirements in mind, it will be overwhelmed and dysfunctional.
Security requirements
Security requirements are incorrect because the question does not mention anything security-related.
Test development
Test development often uses virtual desktop platforms based on some sort of guest OS hypervisor. This environment protects a live environment from any potential coding issues.
A support desk technician must make a custom-length Ethernet patch cable for a user’s desk setup. What tool do they need to create this cable? (Select all that apply.)
- A crimper is a tool used to fix a male jack to a patch cord. The support technician would do this to both ends of the custom cable.
- A cable stripper is a tool that would score the outer jacket just enough to remove it.
- Snips are needed to cut the custom length cable to size and trim the ripcord and the start filler inside the cable. Sometimes snips are integrated on cable stripper tools and can be singular in function.
Punchdown tool
A punchdown tool fixes each conductor into an insulation displacement connector (IDC). This would not be used in this scenario, as there is no punching down of wires into a block.
Which internal component does a mobile device use to acquire single or multi-touch input?
A touch screen is also referred to as a digitizer because of the way it converts analog touch input to digital software instructions. A digitizer sits above a display panel.
Inverter
An inverter component is used to convert from the DC power supplied by the motherboard to the AC power for certain mobile flat panel displays.
Display
The display panel is only a single layer within the screen assembly for a mobile device. Several other display components make up the whole screen.
Trackpad
A trackpad (also referred to as a touchpad) acts as a mouse and is a larger-format device attached as a peripheral rather than built into a laptop.
A user complains the cursor on their laptop jumps around on its own. This is especially bad while they are typing. What could solve this problem? (Select all that apply.)
- On a laptop, if the touchpad sensitivity is too high, typing can cause vibrations that move the cursor. If the touchpad is not needed, it can be disabled. There is generally a function key that will disable the touchpad.
- The touchpad sensitivity can be turned down by installing up-to-date drivers and configuring input options.
Replace the backlight.
The symptoms of a faulty backlight are a display that is very dim and cannot be adjusted with software settings.
Replace the battery.
A faulty battery can cause overheating or the inability to hold a charge. It does not cause problems with the touchpad unless a swollen battery is warping the touchpad.
A user finished setting up their new laptop on the latest Windows operating system and is currently setting up print capabilities. They go to pick up the paper from the printer but everything comes out garbled. What should they troubleshoot first?
Garbled print typically occurs because of a fault in rendering the print job somewhere in the path between the application, printer (driver), page description language, and print device.
Clean the rollers
Vertical or horizontal lines marks that appear in the same place are often due to dirty feed rollers or a damaged or dirty photosensitive drum.
Toner fuser
Toner not fused to paper has symptoms of output that smudges easily. This indicates that the fuser needs replacing.
Creased paper
Most paper jams arise because the media (paper or labels) are not suitable for the printer or because a sheet is creased, folded, or not loaded properly in the tray.
A manager needs to electronically sign many documents while using a laptop. Precision is not required and there is very little money in the budget to spend. What does the manager choose to use as a solution?
A touchpad is a navigation device that is built into laptops and acts as a mouse. Using a finger with the touchpad can cost-efficiently accomplish the manager’s needs.
Touch pen
Most drawing pads and some touch screens can be used with a touch pen or stylus rather than fingers. A stylus allows for more precise control and can be used for handwriting and drawing.
Trackpad
A trackpad acts as a mouse and is a larger-format device attached as a peripheral rather than built into a laptop. It may also be used on desktops.
Drawing pad
A drawing pad refers to a large-format touch device attached as a peripheral. These are also called graphics tablets as they are used in digital art applications.
A laptop user at a company asks the IT department for computer equipment. In addition to an external monitor, the user would like to take advantage of an expansion card. What does IT purchase for the user?
A docking station is a sophisticated port replicator. When docked, a portable computer can function like a desktop machine or use additional features, such as a full-size expansion card.
Port replicator
A port replicator either attaches to a special connector on the back or underside of a laptop or is connected via USB. It provides a full complement of ports for devices such as keyboards, monitors, mice, and network connections.
Serial interface
Serial is one of the oldest and simplest computer interfaces. While not many mobile devices have hardware serial ports, the software serial port is often used.
Laptop ports
Laptops ship with standard wired ports for connectivity. The ports are usually arranged on the left and right edges.
A company offers a bring your own device (BYOD) program at work. Several users approach the company in an effort to receive reimbursement for changing personal phones to the company’s carrier. This will be done by swapping out a subscriber identity module (SIM) card in devices with which network type?
Global System for Mobile Communication (GSM) allows subscribers to use a removable subscriber identity module (SIM) card to use an unlocked handset with their chosen network provider.
LTE
Long-term evolution (LTE) provides an upgrade from CDMA. All 4G and 5G cellular data connections require a SIM card.
CDMA
Code division multiple access (CDMA) means that the handset is directly managed by the provider and there is no removable SIM card.
NFC
Near-field communications (NFC) allow a mobile device to use a close-range service such as contactless payments.
The software-defined networking (SDN) model consists of multiple layers for networking functions that can be accessed and managed via scripting and automation. Which of the following are layers within the SDN model? (Select all that apply.)
- The application layer applies business logic to decide how to prioritize and secure traffic and where to switch the traffic.
- The control layer is the principal innovation of SDN as it interfaces between the application and infrastructure layers and acts as a controller for the automation of networking functions via APIs.
- The infrastructure layer contains the devices (physical or virtual) that handle the actual forwarding (switching and routing) of traffic.
Internet layer
The Internet Protocol (IP) layer is a function of the Open Systems Interconnection (OSI) model that provides packet addressing and routing within a network of networks. Though this functions within the SDN, it is not a main software-defined networking layer.
A user receives a loaner Android mobile phone for use while traveling on business. To charge the device, which traditional cable type will the user need?
Modern Android-based smartphones and tablets use the USB-C connector for wired peripherals and charging. The Micro-B USB and Mini-B connector form factors are only found on old devices.
Lightning
Most iPhone and iPad Apple devices use the proprietary Lightning connector. Some of the latest iPad models, such as the iPad Pro, use USB-C.

A high-definition media interface (HDMI) port is a multimedia port used for connecting computers and other devices to a display for audio/video purposes.
Which of the following causes the ink in an inkjet printer to break up into small pumps, which give an electrical charge when they leave the print head and can either stick to the paper or fall off?
Epson design, the nozzle contains a piezoelectric element, which changes shape when a voltage is applied. The steady stream is the ink sent through the print head, and the ink that falls off is recycled.
Thermal method
The thermal method is when the ink at each nozzle in the print head is heated, creating a bubble. When the bubble bursts, it sprays ink through the nozzle and draws more ink from the reservoir.
Imaging drum
The imaging drum is a round rotating cylinder conditioned by the primary charge roller (PCR) in a laser printer.
Transfer roller
Transfer roller applies a positive charge to the underside of the paper in a laser printer.
A support technician replaces a Wi-Fi card in a laptop. The following day, the laptop user states that the company’s Wi-Fi network signal is weaker than it was before. What does the technician find to be the likely problem?
When replacing a Wi-Fi card, it is important to remember to connect the antenna. The connection is usually a wire with a terminating end that snaps onto the card.
The Wi-Fi card is not seated properly.
A Wi-Fi card is seated into a laptop and is usually a peripheral component interconnect express (PCIe) type connector. Having the card seated incorrectly would render the Wi-Fi card unrecognizable and not function at all.
The incorrect software drivers are installed.
Devices within a computer require software drivers to function. Since the system identified the card properly, then the support technician installed the correct drivers.
The Wi-Fi is not compatible with the new card.
There are varying specifications for Wi-Fi. Since the Wi-Fi is receiving a signal, the Wi-Fi card is compatible with the company’s Wi-Fi system.
Remote wipe, locator apps, device encryption, remote backup, and antivirus software fall under which category of requirements?
Security requirements are correct because all the things listed in the question refer to profile security requirements established for any system.
Resource requirements
Resource requirements are important to consider and meet when setting up a virtualized system and network for virtualized systems to use. If the system is not designed with resource requirements in mind, it will be overwhelmed and dysfunctional.
Test development
Test development often uses virtual desktop platforms that are based on some guest OS hypervisor.
Legacy software/OS
Legacy software applications and operating systems may not perform well if a user’s system has been upgraded.
A technician is using a printer that has text-to-raster conversion. Which of the following is this?
(PostScript) is Adobe’s device-independent PDL and is often for professional desktop publishing and graphical design output.
PDL
A page description language (PDL) creates a raster file from the print commands sent by the software application. A raster file is a dot-by-dot description of where the printer should place ink.
PCL
A printer control language (PCL) is more closely tied to individual features of printer models and can introduce some variation in output depending on the print device.
Infrastructure mode
Infrastructure mode connects the printer to an access point to make it available to clients on the network via an IP address.
What can a cloud developer use to analyze viruses, worms, and Trojans without infecting their computer and network?
A sandbox is an isolated environment to analyze viruses, worms, and Trojans in a space that prevents the researcher’s computer and network from becoming infected.
Test development
Test development often uses virtual desktop platforms based on some guest OS hypervisor.
Cross-platform virtualization
Cross-platform utilization tests software applications under different OSs and resource constraints and is important to ensure the application is compatible across several different environments.
Resource requirements
Resource requirements are important to consider and meet when setting up a virtualized system and network for virtualized systems to use. If the system is not designed with resource requirements in mind, it will be overwhelmed and dysfunctional.
What might be diagnosed by no LED status indicators on a drive?
No LED status indicator lights could indicate that the whole system might not be receiving power or that the individual disk could be faulty.
Bad sectors
A read/write error can indicate faulty sectors in a hard disk drive (HDD). Likewise, a power failure or a mechanical fault can damage a sector. If the technician runs a test utility, such as the chkdsk command, and chkdsk locates more bad sectors each time the technician runs the test, it is a sign that the disk is about to fail.
Keyboard issue
During power-on self-test (POST), three long beeps will indicate a keyboard issue.
Corrupted boot sector
The error message, “Boot device not found,” would indicate a corrupted boot sector.
What is a possible source of data corruption?
Data corruption can occur when particular sectors or blocks fail, meaning that the system cannot open the files stored in these locations or they simply disappear.
Loss of internet access
Although frustrating, loss of internet access will not cause data to become corrupted.
Failing RTC battery
A failing real-time clock (RTC) battery will not corrupt the data. Instead, the main symptom will be incorrect data and time. The RTC battery is known as the complementary metal-oxide-semiconductor (CMOS) battery in older systems.
SMART
Self-Monitoring, Analysis, and Reporting Technology (SMART) is a system utility that can help diagnose drive problems, not cause data corruption.
A technician has tested a computer with extended read/write times and found it to have IOPS reduced from vendor baselines. What should the technician do next?
A computer experiencing extended read/write times and a technician diagnosing it with reduced input/output operations per second (IOPS), has a failing drive. However, the drive has not yet failed, so the first thing to do is perform data backups.
Replace the drive.
Replacing the drive immediately will result in full data loss. However, the drive has not failed yet, so the technician should back up the data before replacing the drive.
Change the PSU.
The technician should replace the power supply unit (PSU) when it is overheating or not delivering consistent power.
Change the power cord.
The technician should replace a frayed power cord when the cord is no longer working.
A user wants to mitigate the risk of data loss by using a disk that underpins the mass storage system and provides fault tolerance. What can the user use?
A redundant array of independent disks (RAID) is an array that appears as a single storage resource or volume and can be partitioned and formatted like any other drive. RAID has a basic level numbered from 0 to 6. There are also nested RAID solutions, like RAID 10.
NVMe
NVMe (NVM express) can be packaged for installation to a PCIe slot as an expansion card or an M.2 slot.
SSD
A solid-state drive (SSD) uses flash memory technology to implement persistent mass storage. Flash memory performs much better than the mechanical components used in hard drives.
mSATA
A mini-serial ATA (mSATA) allows a technician to plug an SSD packaged as an adapter card into the motherboard’s combined data and power port.
A technician suspects a mobile device to have liquid damage. What should the technician do first?
The technician should power off the device to avoid further damage and remove any excess liquid. Next, the technician must disassemble the device to dry the internal components when exposed to liquid.
Replace the battery.
The technician will need to replace the battery when a device has liquid damage; however, this is not the first step.
Replace the screen.
Sometimes liquid damage can result in seeing liquid under the screen. This does not necessarily mean that the screen needs replacing; sometimes, it just needs to dry out.
Request a warranty replacement.
Depending on the warranty policy, a warranty replacement for water damage to a mobile device may be appropriate. However, the first step will be to power down the device before moving forward.
A technician did not install the full complement of modules, which would allow the system to revert to as many channels as are populated. What types of channels would allow this to happen? (Select all that apply.)
- Technicians can use triple-channel memory controllers in some CPUs and supporting chipsets.
- Quad-channel memory controllers are similar to triple-channel as a technician can use them in certain CPUs and supporting chipsets.
Dual-channel
Dual-channel memory controllers effectively have two 64-bit pathways through the bus to the CPU, meaning that they can send 128 bits of data per transfer rather than 64 bits. This feature requires support from the CPU, memory controller, and motherboard but not RAM devices.
Single-channel
Single-channel memory means that there is one 64-bit data bus between the CPU, memory controller, and RAM devices.
An employee uses a device that gives them authentication to release the print job. What is this device?
Badging means the print device has a smart card reader. An employee must present an ID badge to the reader to start the print job.

HDMI
A high-definition multimedia interface (HDMI) is the most widely used video interface. HDMI supports both video and audio. HDMI rates as either standard or high speed.
This can be used individually or in conjunction with other configurations to effectively verify email services and block the transmission of spoofed and unwanted messages. (Select all that apply.)
- The Sender Policy Framework (SPF) record—there must be only one per domain—identifies the hosts authorized to send email from that domain.
- DomainKeys Identified Mail (DKIM) uses cryptography to validate the source server for a given email message. This can replace or supplement SPF.
- The Domain-based Message Authentication, Reporting, and Conformance (DMARC) framework ensures that the developer effectively utilizes SPF and DKIM. A DMARC policy publishes as a domain name system (DNS) TXT record.
Virtual private network
A virtual private network (VPN) enables hosts to connect to the LAN without being physically installed at the site.
Which application protocol underpins file and printer sharing on Windows networks and usually runs directly over the TCP/445 port?
Server Message Block (SMB) is the application protocol underpinning file and printer sharing on Windows networks. SMB usually runs directly over TCP port 445.
Network Basic Input/Output System
Network Basic Input/Output System (NetBIOS) allows computers to address one another by name and establish sessions for other protocols, such as SMB. This uses UDP port 137 for name services and TCP port 139 for session services.
File Transfer Protocol
The File Transfer Protocol (FTP) allows clients to upload and download files from a network server. It uploads files to websites and utilizes TCP ports 20 and 21.
HyperText Transfer Protocol
HyperText Transfer Protocol (HTTP) is usually used to serve HTML web pages or applications hosted on a web server and typically operates over TCP port 80.
A large store chain is eager to reduce the cost of maintaining their servers but is unsure what the best method would be for their use case. The major requirements for the chosen solution are that the store chain needs to own its cloud infrastructure (without sharing with another organization) to maintain maximum privacy and security of the data. Which cloud computing option best meets the store chain’s major requirements?
The private cloud meets the store chain’s two major requirements because it gives organizations greater control over the privacy and security of their data stored in the cloud.
Public cloud
The public cloud is incorrect because there are risks regarding performance and security. The public cloud is a shared resource with other organizations, and a cloud service provider (CSP) runs it.
Hybrid cloud
A hybrid cloud is incorrect because some cloud functions can be done via a public cloud, creating potential vulnerabilities to privacy and security.
Community cloud
Community cloud is incorrect because it requires the store chain to share a hosted private or a fully private cloud with other organizations.
What is a sign that the RTC battery is failing?
The real time clock (RTC) is part of the chipset that keeps track of the calendar date and time and runs on battery power. If the system date or time is wrong, it can indicate that the battery is failing.
Computer crash
Intermittent computer crashes can be difficult to diagnose, but a failing RTC battery is not a cause of computer crashes.
Grinding noise
Grinding noises can indicate mechanical failure on a hard drive disk (HDD), but this does not relate to the RTC battery.
Application crash
Application crashes can be challenging to diagnose, but the RTC battery is not a cause of application crashes.
A display manufacturing company is evolving their current model line to offer a new model of display that does not require backlight. What technology does not require a backlight as each individual pixel is self-illuminating?
In an organic LED (OLED) display, or technically an advanced matrix OLED (AMOLED), each pixel is generated by a separate LED. This means that the panel does not require a separate backlight.
Light-emitting diodes
An LCD must be illuminated to produce a clear image. In a TFT, the illumination is provided by an array of light-emitting diodes (LEDs).
Liquid crystal display
Most mobile devices use a flat-panel screen technology based on a type of liquid crystal display (LCD). A liquid crystal is a compound whose properties change with the application of voltage.
Thin film transistor
In the types of flat panels used for computer and mobile device displays, the liquid crystal elements and transistors are placed on a thin film transistor (TFT).
A user is trying to print visual graphics for an upcoming meeting, but the paper is coming out faded. What should they check first?
For faded or faint prints, if a simple cause such as the user choosing an option for low density (draft output) can be discounted, then this is most likely to indicate that the toner cartridge needs replacing.
Creased paper
If paper is not feeding into the printer check that the paper is not creased, damp, or dirty.
Paper weight
If the printer is feeding multiple sheets also check the paper size and weight.
Orientation
For incorrect page orientation, the paper size and orientation must be set correctly for the print job or the finishing/binding will be aligned to the wrong edge.
A technician researches flat-screen displays to find the perfect model for a conference room. The screen should feature a high viewing angle as the conference room is wide. Which technology does the technician look for when purchasing a flat-screen display?
In-plane switching (IPS) uses crystals that rotate rather than twist. The main benefit is to deliver better color reproduction at a wider range of viewing angles. Most IPS panels support 178/178 degree horizontal and vertical viewing angles.
VA
Vertical alignment (VA) uses crystals that tilt rather than twist or rotate. This technology supports a wide color gamut and the best contrast-ratio performance.
LED
An array of light-emitting diodes (LEDs) can provide illumination in a flat panel. Most smartphone and tablet screens use edge lighting where the LEDs are at the top or bottom of the screen.
LED
A separate LED generates each pixel in an organic LED (OLED) display, or technically, an advanced matrix OLED (AMOLED) display.
A user reports that their reporting resource is not working. They mentioned an error message that they did not write down but are certain that a “HTTP request failed” was a part of the error. What specialized support team will the user contact to resolve this issue?
A web server provides client access using HTTP or its secure version (HTTPS). Given the limited information, this would be the first team to reach out to.
Mail server team
Mail servers primarily use Simple Mail Transfer Protocol (SMTP), which specifies how the user delivers an email from one mail domain to another domain.
Print server team
Print servers rely heavily on Server Message Block (SMB) protocol for file and printer sharing on a Windows network.
File server team
File servers also rely heavily on Server Message Block (SMB) protocol for file and printer sharing on a Windows network.
A logistics company wants to streamline its workflow and track shipments as they move in and around its facilities without barcode scanners. What type of personal area networking solution would best suit this requirement?
Radio-frequency ID (RFID) encodes information into passive tags, which can be energized and read by radio waves from a reader device.
NFC
Near-field communication (NFC) is a peer-to-peer version of RFID. NFC works typically at up to two inches, which would not be a large enough range for this scenario.
Bluetooth
Bluetooth is used to connect peripheral devices to PCs and mobiles and to share data between two systems. No information needs to be transferred to the physical shipments, so this technology would not be the best solution.
Wi-Fi 5
Wi-Fi 5 is a connection that requires physical hardware on both sides of communication, so this would carry an extremely high cost for implementation in this scenario.
A company has a structured cable system installed by a technician. The technician uses a permanent cable that terminates to wall ports and patch panels. What is this mechanism called?
A punchdown block is a mechanism used to terminate wires. A technician can use RJ45 to terminate twisted pair cabling for Ethernet.
RJ45
RJ45 connectors are also known as “8P8C.” Each conductor is a four-pair Ethernet cable that is color-coded.
RJ11
RJ11 typically terminates a two-pair cable used in the telephone systems and with DSL modems.
T568A
T568A is a twisted pair that a technician can use in the TIA/EIA-568. In T568A, the technician wires pin 1 to green/white, wires pin 2 to green, wires pine 3 to orange/white, and wires pin 6 to orange.
What features of the cloud allow multiple users to simultaneously access content and work collaboratively while tracking edits by each user?
File synchronization is an advantage of cloud storage that replicates files between data centers and different devices such as PCs and smartphones. Cloud storage also allows multiple users to access content to work collaboratively simultaneously.
