Which of the following is used to measure the speed of our CPU?
a. MB
b. Mbps
c. MHz
d. RPM
C. MHz
CPU/GPU’s are measured in hertz.
Which of the following internal components is MOST likely needed to communicate with other devices on the internet?
a. CPU
b. GPU
c. PSU
d. NIC
D. NIC
communicate with internet
The NIC is the network interface card, this is where we plug in our ethernet cord and what allows us to connect to the internet.
The CPU is the brain of the computer, used for running all the applications and processes.
The GPU is the graphics processing unit, used to render the graphics and display them on our monitor.
The PSU is the power supply unit, used for powering on all the components on the system.
A user is wanting to purchase a new type of drive. Below are the requirements the user is wanting:
*Non-magnetic drive
*Non-volatile
*Fast
a. SSD
b. HDD
c. RAM
d. ROM
A. SSD
non-magnetic
SSD’s are a form of non-volatile and non-magnetic storage drives that are faster than HDD’s.
HDD’s are a form of magnetic drives.
RAM is volatile and short term
ROM is read only memory.
Which of the following is used to measure how fast data is moving?
a. KB
b. Kbps
c. KHz
d. C4
B. Kbps
kilobits per second is how to measure data in transit/bandwidth/throughput of data.
KB is how we measue the amount of storage on a hard drive.
KHz is how our processors are measured.
C4 is a type of preworkout.
Which of the following is the fastest bandwidth?
a. Kbps
b.Mbps
c. GHz
d. PB
B. Mbps
Megabits per second is faster than Kilobits per second, and this is how data in transit (bandwidth) is measured.
GHz is how we measure our processor speed.
PB is a large storage unit.
A new printer has been recently bought and needs to be set up in the office. Which of the following is MOST likely needed for the printer to ensure it can communicate within the network?
a. Scanner
b. PPM
c. IP Address
d. Default Gateway
C. IP Address
communicate within the network
To be able to communicate on the network, every device must have an IP address. A printer on a network will typically be given a static IP address or be used with a DHCP reservation.
A scanner is an input device that can sometimes be integrated within a printer/scanner multi-function device.
PPM stands for pages per minute and this is the speed that a printer can print.
Default gateway is our routers IP address, which is not necessary for communication with devices on the LAN.
A user recently purchased a new speaker and is having issues with it. The drivers have been updated and the speaker has been turned on. Which of the following should we check FIRST?
a. Compatability settings
b. OEM Manual
c. Output device
d. Misconfigured cables
D. Misconfigured cables
We want to check the easiest and simpliest solution first, out of these options, this will be to ensure that the speaker is correctly plugged into the right peripheral.
Speakers are typically plug and play devices, so compatability shouldn’t be too big of an issue here.
We have the proper drivers already installed for it, the OEM Manual will most like point to checking the cables during set up.
When a new device is plugged in correctly, your computer will typically ask what type of device it is and would you like to use it.
Which of the following would be used to connect to a switch?
a. RJ11
b. RJ45
c. Coaxial
d. Fiber
B. RJ45
The RJ 45 is used to termanate the ehternet cord, which is the wired connection that is used by end nodes to connect together through the switch.
RJ11 is used with POTS
Coaxial is used to connect us to our ISP.
Fiber is the fastest internet service type, using glass tubes filled with light. Used outside of the LAN.
Which of the following internet types uses SFP?
a. Cable
b. Fiber
c. DSL
d. Dial-Up
B. Fiber
SFP is short for small form factor pluggable, and is used to add fiber connections to routers or switches.
A user wants to make a purchase at a vending machine using their cell phone. Which of the following technologies is being used?
a. NFC
b. Bluetooth
c. Wifi
d. IR
A. NFC
NFC can be used on a debit or credit card, and is also used in cell phones via apple pay or google wallet.
Bluetooth is not meant for payments. Has a max distances of 30 feet.
Wifi is meant for connecting wirelessly to a router.
IR stands for infrared and is used in remote controls.
An end user want to watch a video on their mobile device on their smart tv screen. Which of the following technologies would allow for them to do this wirelessly?
a. Mirroring
b. Casting
c. NFC
d. Bluetooth
B. Casting
Casting is where we can cast our current phone screen to place it on our tv screen.
Mirroring requires us to have some type of wire.
NFC is for wireless payments.
Bluetooth is used for pairing two devices together.
