Question 1

Which unit is responsible for converting the data received from the user into a computer understandable format?
A)Memory Unit
B)Arithmetic & Logic Unit
C)Input Unit
D)Output Unit

Accepted Answer

The Input Unit is responsible for converting data received from the user or from external devices into a format that the computer can understand, typically binary form.

Question 2

The only language which the computer understands is ______________
A)Assembly Language
B)Binary Language
C)BASIC
D)C Language

Accepted Answer

The only language that the computer understands is binary language. Binary language is a system of representing information using only two digits, 0 and 1. This is because computers are electronic devices that can only understand two states, on and off. Binary language is used to represent all of the data that is stored and processed by a computer, including programs, data, and instructions.

Question 3

The smallest unit of data in computer is ________________
A)Byte
B)Nibble
C)Bit
D)KB

Accepted Answer

The smallest unit of data in a computer is a bit, which represents a binary digit, either 0 or 1.

Question 4

Which of the following is not a function of the Input Unit?
A)It reads instructions and data from the outside world
B)It converts the data into computer acceptable format
C)It makes the data into user understandable format
D)It supplies the data and instructions to the computer for further processing

Accepted Answer

The input unit is responsible for taking input from the user or from other devices and converting it into a format that the computer can understand. It does not convert data into a user understandable format; that is typically the role of the output unit or software applications designed for data presentation.

Question 5

The process of producing useful information for the user is called ___________
A)Controlling
B)Outputting
C)Inputting
D)Processing

Accepted Answer

The answer of The process of producing useful information for...

Question 6

The output unit converts the data entered by the user into computer understandable form.
A)True
B)False
C)none
D)all

Accepted Answer

The output unit converts the data from the computer into a form understandable by the user, not the other way around. The input unit is responsible for converting user-entered data into computer understandable form.

Question 7

VDU stands for __________
A)Virtual Display Unit
B)Visual Display Unit
C)Virtual Detection Unit
D)Visual Detection Unit

Accepted Answer

VDU stands for Visual Display Unit, which is a term often used to refer to a monitor or screen that displays output from a computer or other devices.

Question 8

Which of the following is not a function of the Output Unit?
A)It produces results that can be easily understood by the user
B)It accepts the results produced by the computer
C)It supplies the data and instructions to the outside world
D)It supplies the data and instructions to the computer for further processing

Accepted Answer

The Output Unit is responsible for converting the computer's processing results into a form understandable by users, accepting results from the computer, and supplying data and instructions to the outside world. It does not supply data and instructions to the computer for further processing; that is the function of the Input Unit.

Question 9

Components that provide internal storage to the CPU are ______
A)Registers
B)Program Counters
C)Controllers
D)Internal chips

Accepted Answer

Registers are small storage locations within the CPU that hold data temporarily for processing.

Question 10

Saving data and instructions to make them readily available is the job of __________
A)Storage Unit
B)Cache Unit
C)Input Unit
D)Output Unit

Accepted Answer

The storage unit is responsible for saving data and instructions so they can be accessed and used by the computer when needed.

Question 11

The two basic types of memory in a computer are ________
A)Primary and major
B)Primary and Secondary
C)Minor and Major
D)Main and virtual

Accepted Answer

The two basic types of memory in a computer are Primary and Secondary. Primary memory refers to the main memory (RAM) directly accessible by the CPU, while Secondary memory refers to external storage devices like hard drives and SSDs.

Question 12

Which of the following is used to hold running program instructions?
A)Primary Storage
B)Virtual Storage
C)Internal Storage
D)Minor Devices

Accepted Answer

Primary Storage, also known as main memory or RAM, is used to hold the instructions of a running program as well as the data it needs. This allows the CPU to quickly access these instructions and data, which is essential for the efficient execution of programs.

Question 13

Which of the following is non-volatile storage?
A)Backup
B)Secondary
C)Primary
D)Cache

Accepted Answer

Secondary storage, such as hard drives, SSDs, and external storage devices, is non-volatile, meaning it retains data even when the power is turned off. Primary storage (RAM) and cache are volatile, losing their contents without power. "Backup" is a process, not a storage type.

Question 14

Which of the following is used in main memory?
A)SRAM
B)DRAM
C)PRAM
D)DDR

Accepted Answer

The answer of Which of the following is used in...

Question 15

Which of the following are types of ROMs?
A)SROM & DROM
B)PROM & EPROM
C)Only one type there is no further classification
D)PROM & EROM

Accepted Answer

PROM (Programmable Read-Only Memory) and EPROM (Erasable Programmable Read-Only Memory) are types of ROM that allow data to be written to them under specific conditions. PROM can be programmed once, while EPROM can be erased and reprogrammed using ultraviolet light.

Question 16

First graphical user interface used commercially was introduced in
A)1970
B)1975
C)1978
D)1980

Accepted Answer

The answer of First graphical user interface used commercially was...

Question 17

Which type of user interface provide input by typing a string in the keyboard ?
A)Graphical user interface
B)Command line user interface
C)Natural language interface
D)Menu interface

Accepted Answer

Command line user interface allows users to interact with the system by typing commands in text form, which is directly entered through the keyboard.

Question 18

In graphical user interface of operating system, to point a file, a user uses:
A)pointer
B)common line interface
C)file-based interface
D)voice based interface

Accepted Answer

A pointer, often controlled by a mouse or touchpad, is used in graphical user interfaces to select or point to files and other on-screen elements.

Question 19

Files and directories of graphical user interface of operating system programs are known as
A)commands
B)graphics
C)text
D)folders

Accepted Answer

Files and directories in the context of a graphical user interface (GUI) of operating systems are visually represented as folders. This metaphor helps users to easily navigate and organize their data.

Question 20

We write programs in?
A)Low-Level Language
B)Middle-Level Language
C)High-Level Language
D)Decimal-Format

Accepted Answer

High-Level Language is used to write programs because it is easier to understand and use than other languages.
