Answer 13

Control Unit / Directing and coordinating operation

Question 14

It gets the instructions from the memory, interprets them, and guides the computer’s operation.

Answer 14

Control Unit / Directing and coordinating operation

Question 15

It controls all the units of the machine and coordinates them.

Answer 15

Control Unit / Directing and coordinating operation

Question 16

It is responsible for managing the transition between other units of a computer of data and instructions.

Answer 16

Control Unit / Directing and coordinating operation

Question 17

It does not handle or store information.

Answer 17

Control Unit / Directing and coordinating operation

Question 18

operations such as addition, subtraction, multiplication, and division are performed. By making repeated use of the above operations, all complex operations are completed.

Answer 18

Arithmetic

Question 19

Logic operations such as comparing, selecting, matching, and combining data are performed.

Answer 19

Logic Section -

Question 20

It is the computer’s storage space where data is to be processed and the instructions necessary for processing are stored.

Answer 20

Computers memory

Question 21

What are the Primary Types of Memory

Answer 21

1. cache memory
   2.Primary memory / Main memory
2. Secondary memory

Question 22

It is used to carry the data and program sections that are most commonly used by the CPU. Sections of data and programs are transferred by the operating system from the disk to the cache memory, from which the CPU can access them.

Answer 22

Cache Memory -

Question 23

It is the CPU’s internal memory for storing data, program, and program output. It is a read / write memory that stores data before the computer is running. As soon as the computer is turned off, the data is removed.

Answer 23

Random Access Memory

Question 24

RAM meaning

Answer 24

Random Access Memory

Question 25

It’s slower than the primary memory. They are used permanently for storing data / information. CPU does not explicitly access these memories, but they are accessed by input-output routines. It is also known as external or non-volatile memory.

Answer 25

Secondary Memory -

Question 26

-. It is also known as external or non-volatile memory.

Answer 26

Secondary Memory

Question 27

It just contains the data and instructions that the machine is actually running on. It has a restricted capacity and when power is turned off, data is lost.

Answer 27

Primary Memory/Main Memory -

Question 28

It is used to carry the data and program sections that are most commonly used by the CPU. .

Answer 28

Cache Memory -

Question 29

Sections of data and programs are transferred by the operating system from the disk to the cache memory, from which the CPU can access them

Answer 29

Cache Memory -

Question 30

What are the two types of RAM

Answer 30

1. static RAM (SRAM)
2. Dynamic RAM (DRAM)

Question 31

What kind of RAM has 6 transistors per bit

Answer 31

Static RAM (SRAM)

Question 32

What kind of RAM has 1 transistors and 1 capacitor- it is also common use

Answer 32

Dynamic RAM

Question 33

What is the permanent memory

Answer 33

RAM or Random Access Memory

Question 34

stores instructions such as these that are required to start a machine. This operation is known as the bootstrap method.

Answer 34

ROM

Question 35

used not only in laptops, but also in other consumer devices, such as washing machines and microwaves.

Answer 35

ROM

Question 36

Hard-wired computers containing a pre-programmed set of data or instructions were the very first ROMs. These forms of ROMS, which are cheap

Answer 36

MROM (Masked ROM) -

Question 37

• It’s a read-only memory that a user can only change once. The user used to purchase a blank and enter the desired material. There are tiny fuses within the chip, which during programming are burnt open. It can only be programmed once and it is not erasable.

Answer 37

PROM (Programmable Read Only Memory)

Question 38

By exposing it to ultraviolet light for a time of up to 40 minutes, it can be erased. An electrical charge is stuck in an insulated gate region during programming. Since the charge has no leakage course, the charge is maintained for over 10
years.

Answer 38

EPROM (Erasable and Programmable Read Only Memory)-

Question 39

• It is electrically programmed and erased. Around ten thousand times, it can be deleted and reprogrammed. Both programming and erasing take between 4 to 10 ms (milliseconds), it is possible to selectively delete and program any spot. Rather than erasing the entire chip, can be erased one byte at a time. Hence, the reprogramming process is versatile but sluggish.
