Q

What does the motherboard look like?

Study These Flashcards
A

Large circuit board with microchips on it
Many sockets, slots, ports, plugs on so you can plug stuff into it

25
What part of the human body is the motherboard similar to?
spinal cord
26
What is the function of the motherboard?
central communication hub of the comptuer --> all data goes through the motherboard
27
What should you note when buying a motherboard?
ensure it has the proper sockets, slots, or ports that you need to connect your devices
28
What does the CPU look like?
- small, rectangular circuit board with one main microchip on it - backside has connector pins/dots - sometimes may be coverd with a metal protector
29
What does the CPU do?
performs math or logic calculations
30
What are examples of math calculations?
addition, subtraction, multiplication, division, exponents
31
What are some examples of logic calculations?
less than, greater than, equal to, AND, OR
32
What part of the human body is the CPU similar to?
the brain
33
What should you note when buying a CPU?
Ensure that it fits into the socket that your motherboard has Ensure that it has the power for the apps/games you want to run
34
What is the general rule of thumb for faster CPUs?
More Ghz Newer More CPU Cores
35
What does the RAM look like?
- Small rectangular circuit board with microchips on it - One side/edge has connector pads - microchips are sometimes covered with a metal protector
36
What does the RAM do?
RAM stores the data of currently running programs It is fast and temporary data storage, but has limited capacity.
37
What happens to the data in RAM after a program is closed/done?
data is freed so RAM can store data of the next running program
38
What part of the body is the RAM like?
short term memory of the brain
39
What should you note when buying RAM?
ensure it is compatible with the RAM slot in the motherboard (usually DDR4) ensure ther is enough RAM to run the apps/games you want
40
What were the 4 types of Storage explored?
Traditional Hard Drives SSD using an SATA connecor SSD that looks like a circuit but uses SATA connector SSD using NVME connector
41
What does the traditional Hard Drive look like?
large metal box with SATA data and SATA power ports on one side
42
What does the storage do?
stores data of programs that are NOT currently running & the files that the programs use storage is much slower than RAM, but can store lots of data
43
When does the data in the hard drive/SSD erase?
when we tell it to
44
What part of the human body is the storage similar to?
long-term memory of the brain
45
What should you note when buying storage?
Ensure you have enough space to store all the data of your programs as well as the data that those programs use
46
What does the power supply unit look like?
- large metal box - AC powerconnector on one side - DC powercable(s) on the other
47
What does the PSU do?
1. convert 110V of AC power to 5-12V DC power that computers can use 2. distribute the power inside of the PC case to all the parts of the computer (eg. motherboard, hard drives, GPUs, etc.)
48
What part of the body is the PSU similar to?
human digestive system
49
What should you note when buying a PSU?
Ensure that it has enough Watts to run the parts inside the computer.
50
What happens if you don't have enough Watts to run the parts inside the computer?
The computer might crash or produce incorrect output
51
What does the Case/Tower look like?
large metal boxes that all computer parts are installed into
52
What is the function of a case/tower?
1. provide a rigid structure to install your computer parts 2. provide protection against the outside environment
53
What part of the human body is the Case/Tower like?
Skeletal system - 1st function Integumentary System (skin) - 2nd function
54
What can the cooling look like?
fans heat sinks liquid cooling air conditioning
55
What does the cooling do?
ensure that hot microchips remain in a specified temperature range (usually 100℃)
56
What part of the human body is the cooling like?
sweat
57
Explain how the different types of cooling work.
Fans - blow hot air away Heat Sinks - distribute the heat by increasing surface area via metal Water cooling - uses water to transport heat away from hot microchips
58
What does the CPU connect to the motherboard?
AMD - Socket AM 4 Intel - Socket 1700 (usually)
59
How does the RAM connect to the motherboard?
DDR4
