Q

Bus

A

Physically connect the processor, memory and I/O devices

17
Q

Fetching

A

Instruction from memory to processor

18
Q

Decoding

A

The instruction on the processor

19
Q

Executing

A

The instruction by calculator with the ALU, reading data from memory, writing data in memory

20
Q

Cores properties

A

As cores increase in number, more instructions Cain be fetched/decoded/executed

21
Q

Volatile

A

Main memory does not retain data and instructions stored in it
Does not require energy
Data is lost when there is no energy

22
Q

Secondary storage

A

Hard disk drivers, ssd, optical media

23
Q

Magnetic hard drivers

A

Use magnets to read/write on little particles on a spinning disk

24
Q

Optical media

A

Work by shining a laser at the end of a movable arm on a spinning disk. The pits and lands from the disk reflect or disperse the light

25
Q

Solid state drive

A

No moving parts -> rigid

Complex electrical circuits to store data

26
Q

Advantage for magnetic

A

Cheap -> good to store large capacities

Fast read/write

27
Q

Optical media advantage

A

Use to distribute data/software without using a network

28
Q

Solid State advantage

A

Very fast read/write speed
No moving parts -> robust
Small size per bit

29
Q

Magnetic media disadvantage

A

Use moving parts -> less robust

30
Q

Optic media disadvantage

A

Low capacity
Easily corrupted
Slowest read speed
Very slow write speed

31
Q

Solid State disadvantage

A

Expensive

32
Q
