Q

What’s the difference between analog and digital signals?

A

Analog- Are susceptible to interference resulting in lower quality images and slower data transmission.

Digital- Has less interference resulting in higher quality images and faster data transmission.

17
Q

OLED

A

Organic LED: Is a screen that uses organic compounds to display an image.
Environmentally Friendly

18
Q

CRT

A

A legacy screen that is a tube with a phosphorus film on the front and lasers are used to write the picture onto.

Must be recycled appropriately. Will emit a poisonous gas if thrown out window

19
Q

What is resolution?

A

Usually represented by how many pixels you could display horizontally vs vertically.

Native resolution is the exact number of dots on a physical screen
Supported resolution is the number of dots that could be emulated electronically on the screen.

20
Q

Aspect Ratio

A

is simply the proportional relationship between the width and height of the display.

4: 3 is Full screen
16: 9 is Widescreen

21
Q

Analog Signals

A 
Are susceptible to interference resulting in lower quality images and slower data transmission.
VGA
S-Video
Component RGB
Composite -does both video and audio
22
Q

Digital Signals

A

Has less interference resulting in higher quality images and faster data transmission. (You either have it or don’t)
HDMI
DisplayPort
DVI

23
Q

What are the three types of Digital Visual Interface (DVI)?

A

DVI-D (only digital)
DVI-A (only analog)
DVI-I (both digital and analog, I stands for integrated)

24
Q

KVM Switch (Keyboard Video Mouse)

A

Allows you to control multiple computers with a single set of KVM (Will commonly see a KVM switch in a server) *Almost always uses VGA ports *still used today. Simple port. Does not require complicated information to be sent

25
Q

!! Virtualization !!

A

The idea that you can replicate an operating system on top of your main system
(EX: A person has one computer, each one has its own operating system. Can have Windows 7 virtual machine and a Windows 10 at the same time)

26
Q

!! Multicore Support !!

A

CPUs have cores (EX: Some will say they have x amount of cores). Kind of like a brain for the CPU. Each core can do its own task at a time. The more cores you have, the more your CPU can do. Every Operating system needs at least ONE core.

27
Q

!! Hyperthreading !!

A

Is used in a CPU. Will split the physical cores and treat them as separate cores. (Is tricking the CPU into thinking it has more cores than it actually has. Referring to AMD Ryzen 16 core product → 16 cores is probably not real. There is probably hyperthreading going on)

28
Q

!! “Flashing the BIOS” !!

A

The idea where you are erasing the entire memory. Ie. Erasing everything from the BIOS and replacing it with new data. The only way to update BIOS.

29
Q

!! BIOS (Basic Input Output System, Scary blue screen) !!

A

can let you change boot order, turn on virtualization, etc. Is a read-only memory. CMOS chip is where the BIOS is stored but it’s volatile.
