Firewall
Hardware networking appliance acting as a concentrator or connector for cable segments to a modem, patch panel, or router port
Switch
Where is the physical connection to the cable made in the computer using a transceiver port?

Power adapters for computers come in?
110-120V and 220-240V
Yellow wires are for this voltage?
12V
Orange wires are for this voltage?
3.3V
Red wires are for this voltage?
5V
What color is the ground wires?
Black
For a modern computer, the output rating of rail (or rails) is the most important factor and the most heavily used in terms of voltage?
12V
This may indicate a problem with the power supply, the motherboard problem, or a faulty onboard speaker
No beeps
Repeating short beeps would indicate?
Power supply fault or a motherboard problem
Would indicate a keyboard issue?
Three long beeps
Would indicate a video adapter error?
One long, three short beeps
A problem with a memory controller is expressed by this range of sound?
Continuious beeps
Some most likely causes are software, disk/file corruption problems, or malware issues of this?
Application crashes
This printer uses a stepper motor, pulley, and belt (to move the print head) along with a guide shaft (to keep the print head stable) and sensors (to detect the position of the print head)
Inkjet Printer
Which of the following components will the administrator need to calibrate for every print job manually?
Print bed
This mechanical portion of a image drum applies a uniform -600V electrical charge across the drum’s surface.
Primary charge roller
This enables programmers and application administrators to ensure that the application used by clients is always updated with the latest code
Application Virtualization
This is a lab and testing environment that enables a means to test software and applications under different resource constraints and operating systems.
Cross-platform Virtualization
Typically based on a guest operating system hypervisor, is designed to run on regular desktops and workstations while supporting legacy software and operating systems
Client Side Virtualization
What issue is occurring when there is no light-emitting diode (LED) lit on a hard drive disk (HDD)
Faulty disk
Will provide clues on whether the disk initiated and formatted properly for Windows to use it.
Windows disk management
Which of the following signs would indicate an overworked hard drive disk (HDD) due to insufficient system random access memory (RAM)?
Constant LED activity
Which redundant array of independent disks (RAID) volume type will immediately fail if one hard disk drive (HDD) fails?
RAID 0
The DNS uses root servers at the hierarchy top, represented by a trailing dot at the end of this
FQDN Fully Qualified Domain Name
This software can convert scanned text into digital documents, ready for editing
Optical Character Recognition (OCR)
This is a device-independent page description language (PDL) often used for professional desktop publishing and graphical design output
Adobe Postscript (PS)
This indicates that the primary charge roller is dirty or damaged or that the high voltage power supply to the developer unit is malfunctioning
Black stripes
Virtual Desktop Infastructure VDI in the cloud is also known as
Desktop as a Service DaaS
Is a means of provisioning IT resources, such as servers, load balancers, and storage area network (SAN) components, quickly
Infastructure as a Service IaaS
Deploys servers and storage network infrastructure
Platform as a Service Paas
One advantages of cloud storage is automated sharing between different device which is known as
File Synchronization
Is a model of provisioning software application
Software as a Service SaaS
Means that the service experiences very little downtime. For example, a service with “Five Nines” or 99.999% availability experiences only 5 minutes and 15 seconds annual downtime
High Availability
Where several organizations share the costs of either a hosted private or fully private cloud.
Community Cloud
Refers to the system’s ability to handle changes to demand in real-time. A system with high elasticity will not experience loss of service or performance if demand suddenly doubles.
Rapid Elasticity
Provides resources between SaaS and IaaS.
Platform as a Service PaaS
