Itgs Computer hardware

Question 1 of 23

1

Memory VOLATILE

Select one of the following:

  • Only stores information to run programs while the PC is off.
    Don`t requires electricity to store data using transistors and capacitor

  • Retains data even when the computer is off. Examples in old computers: paper, punched tape
    and floppy disks

  • Only stores information to run programs while the PC is on. Reset when the PC is
    turned off. Requires electricity to store data using transistors and capacitor

  • Don`t retain data even when the computer is on. Examples in old computers: paper, punched tape
    and floppy disks

Explanation

Explanation

Question 4 of 23

1

Bridges

Select one of the following:

  • is the area where the computer stores or remembers data.

  • Manage how data and instructions are transferred between devices

  • provides the CPU with its instructions.

  • Primary storage

Explanation

Question 5 of 23

1

Cores

Select one of the following:

  • Manage how data and instructions are transferred

  • is the time for components to respond to a request

  • communicate through channels therefore doubling cores does not double speed

  • Retains data even when the computer is off.

Explanation

Question 6 of 23

1

Memory

Select one or more of the following:

  • Used to access the performance of a computer.

  • Examples Registers, cache, RAM, ROM and Virtual

  • Stores program operations and data while the program is being executed.
    Memory

Explanation

Question 7 of 23

1

Storage means

Select one of the following:

  • Renders images, frees up the CPU for other tasks

  • Retain programs and files long term, even when not in use.

  • executes programs using the fetch-decode-execute cycle

Explanation

Question 8 of 23

1

Benchmarking means

Select one or more of the following:

  • A test used to access the performance of a computer. Different types of software are used depending on the computers purpose.

  • Stores program, operations and data while the program is being executed.

  • Registers, cache, RAM, ROM and Virtual Memory

  • CPU speed (cycles per second)

Explanation

Question 12 of 23

1

Cache is a small amount of memory which is a part of the CPU - closer to the CPU than RAM. It is used to temporarily hold
instructions and data that the CPU is likely to reuse.

Select one of the following:

Question 14 of 23

1

Larger the Cache =

Select one or more of the following:

  • indicates how fast the CPU can run.

  • determines how many instruction cycles the CPU can deal with in a second.

  • less data can be stored closer to the CPU

  • more data can be stored closer to the CPU

Explanation

Question 15 of 23

1
