### Byte is a combination of?

• A.

8bits

• B.

16bits

• C.

32bits

• D.

64bits

A. 8bits
Explanation
A byte is a unit of digital information that consists of 8 bits. Each bit can represent either a 0 or a 1, and when combined, they form a byte. Therefore, the correct answer is 8 bits, as it accurately describes the composition of a byte.

### Combination of four bits is?

• A.

Sextant

• B.

Nibble

• C.

Forte

B. Nibble
Explanation
A combination of four bits is called a nibble. In computing, a bit is the basic unit of information, representing either a 0 or a 1. A nibble consists of four bits, allowing it to represent 16 different values (2^4). Nibbles are commonly used in hexadecimal notation, where each nibble corresponds to a single digit (0-9, A-F). By combining four bits into a nibble, it becomes easier to represent and manipulate larger binary numbers.

### A Command is a kind of?

• A.

Coded message

• B.

Encrypted message

• C.

Open message

A. Coded message
Explanation
A command is a type of coded message because it is a specific set of instructions or directives that are written in a particular format or language. These instructions are often used to control or operate a system, device, or program. By being coded, the message is structured in a way that can be understood and executed by the intended recipient, whether it is a computer, a person, or a machine.

### Word is the combination of?

• A.

1 or more than 1 bit

• B.

0 or more than 1 k/bytes

• C.

2 or more than 2 bytes

• D.

2 or more than 2 m/bytes

C. 2 or more than 2 bytes
Explanation
A word is typically defined as a fixed-size group of bits or bytes that can be processed as a unit by a computer. It is a basic unit of data storage and processing in a computer system. Therefore, the correct answer is "2 or more than 2 bytes" as a word can be composed of multiple bytes.

### Firmware is defined as ____ embedded into the hardware?

• A.

Microchip

• B.

Software

• C.

Circuit

• D.

Platinum

B. Software
Explanation
Firmware is a type of software that is embedded into the hardware of a device. It is responsible for controlling the device's functions and operations. Unlike regular software, firmware is stored in non-volatile memory and is not easily modified or updated by the user. It is designed to be permanently installed in the hardware and provides the necessary instructions for the device to function properly. Therefore, the correct answer is "Software" as it accurately describes the nature of firmware being embedded into hardware.

### Logic is a ____ which controls the way in which computers work

• A.

Set of rules

• B.

Combinations of data

• C.

Diagram of data

• D.

Flowchart of database

A. Set of rules
Explanation
A set of rules is the correct answer because logic refers to the principles and reasoning behind the functioning of computers. These rules dictate how computers process and manipulate data, make decisions, and execute instructions. Logic provides the framework for the logical operations and algorithms that computers follow to perform tasks and solve problems. It governs the flow of information and the order in which operations are carried out, ensuring that computers work in a systematic and organized manner.

### 0 and 1, in their endless combination constitute Binary System on which Computers are based

• A.

True

• B.

False

A. True
Explanation
The statement is true because the binary system is the foundation of how computers operate. In the binary system, only two digits, 0 and 1, are used to represent all data and instructions. These digits are used to represent the on and off states of electronic switches within a computer's hardware. By combining these two digits in various sequences, computers are able to represent and process complex information. Therefore, the endless combination of 0 and 1 forms the basis of the binary system, which is fundamental to computer technology.

### Bit is the basic unit of Inverters, It can have -

• A.

1 & 0

• B.

1 to 8

• C.

0 to 64

• D.

1 to 1024

A. 1 & 0
Explanation
The explanation for the given correct answer is that a bit is the basic unit of information in computing and can have two possible values, 1 and 0. These values represent the binary system, where 1 typically represents "on" or "true" and 0 represents "off" or "false". Therefore, a bit can only have the values 1 and 0.

### Compiler is a programme which translates -

• A.

High-level language program into Machine language

• B.

Mid-level language program into Machine language

• C.

Machine language program into Machine language

• D.

Machine language program into High-level language

A. High-level language program into Machine language
Explanation
A compiler is a program that translates high-level language programs into machine language. High-level languages are designed to be more human-readable and easier to write, while machine language is the low-level language that computers can understand and execute. Therefore, a compiler takes the high-level language code and converts it into machine language instructions that the computer can directly execute. This allows the programmer to write code in a language that is more intuitive and abstracted from the underlying hardware, while still being able to run it on the computer.

### What is L.C.D?

• A.

Liquid Crystal Display

• B.

Light Crystal Display

• C.

Light Clone Display

• D.

Line Code Display

A. Liquid Crystal Display
Explanation
The correct answer is Liquid Crystal Display (LCD). LCD is a type of display technology that uses liquid crystals to produce images. It is commonly used in electronic devices such as televisions, computer monitors, and smartphones. The liquid crystals in an LCD panel react to electric current, allowing them to control the amount of light passing through and create the desired image. LCD displays are known for their thinness, energy efficiency, and high image quality.
