Processing Units
Name the 2 types of processing units.
CPU (Central Processing Unit) and GPU (Graphical Processing Unit)
In what order does a CPU run an instruction?
fetch - decode - execute - repeat
What are 3 types of optical storage media?
CD, DVD and Blu-Ray
Name 6 types of storage devices.
6 of the following:
RAM
HDD
SSD
Cache
Which processing unit would be better suited for multitasking?
CPU (Central Processing Unit)
What is a bus?
Buses are high speed internal connections used to send control signals and data between the processor and other components.
What is RAM best suited to be used for?
Loading applications
Browsing the internet
What task is a flash drive best suited for?
transferring data from one computer to another
What is computer processing?
Computer processing is a series of actions performed by a microprocessor when it receives information.
Name 3 types of registers.
Three of the following:
MAR (memory address register)
MDR (memory data register)
CIR (current instruction register)
ACC (accumulator)
Program counter
Which optical storage media has the least storage capacity?
CD
What are possible disadvantages of using HDD?
Include some of the following:
Lot of moving parts which affect the reliability
Easily damaged
Noisy
Name 3 advantages of using a GPU over a CPU.
Three from the following:
Good at parallel processing
Can be used in specialised cases
Can process large amount of data at a higher speed
What is function of a control unit?
It fetches, decodes and controls the sequence and performance of the instructions. It also controls the hardware and the functioning of other components of the CPU like ALU and registers.
What are possible disadvantages of using cache?
Some of the following:
Caches can be corrupted which makes the stored data no longer useful
If cache gets too big, it will slow down and reduce the performance of the computer
Sometimes an app cache might old old or outdated data, creating misleading or confusing information to the user
Describe RAM.
Included some of the following points:
Internal chip where data is temporarily stored when running applications
Volatile
Store data, files or parts of operating systems which is being used
