GPU
List all of the computer components
Motherboard
CPU / GPU
Hard Drive
RAM
SSD
Power supply
Case
Cooling system
Wireless card
Motherboard brief description
1) Main component of the computer
2) Where every component gets connected
3) Makes other components communicate with each other
CPU (Central processing unit) brief description
1) Usually has low data storage but good at complex jobs
2) Everything that happens in the computer, goes through the CPU
3) Where most of the programs are run from
Hard drive brief description
1) Where all the data is stored
2) Good at storing data but slow at accessing it
3) It isn’t always able to give the needed info to the CPU; to avoid this, we use the RAM.
RAM (Random access memory) brief description
1) Stores data but less space available
2) It can access information faster than the hard drive
3) Can’t permanently store data, it is a short memory system
SSD (Solid State Drive) brief description
1) Same goal as the hard drive but faster and more durable
2) It can be used alone on computers or paired with a hard drive, though it is more expensive.
GPU (Graphics processing unit) brief description
1) An entire computer dedicated only to graphics, and it is responsible for what comes up on your screen.
Power supply brief description
1) Takes electricity from the outlet and puts it into the computer, making it work.
2) Has to be powerful enough for your other components.
Case brief description
1) Case for all of the components
2) Big enough to fit all the components
Cooling system brief description
1) Cools down the CPU and GPU when it gets hot
2) Liquid cooling and air cooling
Wireless card brief description
1) The computer has a wireless card if it supports Wi-Fi without an ethernet cable.
CPU components?
1) Arithmetic Logic Unit
2) Cache
3) Register
4) Control Unit
Arithmetic logic unit function
- arithmetic calculations
- make logical decisions
Cache function
- stores data temporarily
- provides fast access to frequently used data and instructions
- info fetched or written to cache is done more quickly than info fetched or written to main memory
Registers function
- tiny, super fast pieces of onboard memory inside the CPU
- a type of memory used to quickly transfer, store and accept data by the CPU
4 parts of a register?
Accumulator
Program counter
Memory data register
Memory address register
CPU component that carries out decisions?
Arithmetic logic unit
Network transmission protocol used to transmit secure web data?
HTTPS (S is to make sure it’s secure)
Purpose of the accumulator?
Hold data being processed and results of processing
