Q-4)   BIT stands for

(a)

(b)

(c)

(d)

(e)

Explanation:

A bit is the most basic unit of information in computing.

It is short for binary digit, which means that it can only have one of two values, 0 or 1.

Large denominations of computer memory are composed of bits, moving up through bytes, kilobytes, megabytes, gigabytes and terabytes.

Bits are usually grouped into bit multiples called bytes to store data and execute instructions. A group of eight bits is usually defined as a byte, while four bits are called a nibble.


Q-5)   What is the full form of KB related to computers?

(a)

(b)

(c)

(d)

(e)

Explanation:

In the metric system, a kilo is 1,000, and in some cases, a kilobyte is defined as 1,000 bytes. This definition is commonly used by storage medium companies to measure data transfer speeds.

But because computers work in binary, computer scientists usually define a kilobyte as 210, or 1,024 bytes. Computer scientists used the term "kilo" because a kilobyte is close enough to 1,000 bytes.

The abbreviation for kilobyte is kB in the metric system (1,000 bytes) or KB in the binary system (1,024 bytes).

Some groups have proposed the name kibibyte for a unit of 1,024 bytes to prevent confusion. The abbreviation for kibibyte is KB.


Q-6)   ‘WWW’ stands for _________.

(a)

(b)

(c)

(d)

(e)

Explanation:

WWW stands for World Wide Web.

It is a system of interconnected documents accessed through the internet.

The world wide web was invented by Tim Berners-Lee.

The world wide web was invented in 1989.

A webpage is the page consisting of information on the world wide web


Q-7)   What is the full form of CRT ?

(a)

(b)

(c)

(d)

(e)

Explanation:

A cathode-ray tube (CRT) is a specialized vacuum tube in which images are produced when an electron beam strikes a phosphorescent surface. Most desktop computer displays make use of CRTs. The CRT in a computer display is similar to the "picture tube" in a television receiver.


Q-8)   CPU stands for __________.

(a)

(b)

(c)

(d)

(e)

Explanation:

CPU is short for Central Processing Unit. It is also known as a processor or microprocessor.

It's one of the most important pieces of hardware in any digital computing system – if not the most important.

Inside a CPU there are thousands of microscopic transistors, which are tiny switches that control the flow of electricity through the integrated circuits.

You'll find the CPU located on a computer's motherboard.

A computer's motherboard is the main circuit board inside a computer. Its job is to connect all hardware components together.

Often referred to as the brain and heart of all digital systems, a CPU is responsible for doing all the work. It performs every single action a computer does and executes programs.


Q-9)   __________ is a form of denial of service attack in which a hostile client repeatedly sends SYN packets to every port on the server using fake IP addresses.

(a)

(b)

(c)

(d)

(e)

Explanation:

An SYN flood attack is a type of denial-of-service (DoS) attack on a computer server. This exploit is also known as a half-open attack. SYN floods are one of several common vulnerabilities that take advantage of TCP/IP to overwhelm target systems. SYN flood attacks use a process known as the TCP three-way handshake.


Q-10)   What is the full form of LSI?

(a)

(b)

(c)

(d)

(e)

Explanation:

Large-scale integration (LSI) is the process of integrating or embedding thousands of transistors on a single silicon semiconductor microchip. LSI technology was conceived in the mid-1970s when computer processor microchips were under development.


Q-11)   What does RAM stand for ?

(a)

(b)

(c)

(d)

(e)

Explanation:

RAM stands for random access memory, a component that allows your computer to store data short-term for quicker access. Your computer loads the program or document you request from the storage disk to memory and then accesses each piece of information from the memory. Because so many operations are dependent on memory, the amount of RAM you have plays a critical role in the speed of your system’s performance. 


Q-12)   RAM stands for __________.

(a)

(b)

(c)

(d)

(e)

Explanation:

Random access memory (RAM) is a computer's short-term memory, where data that the processor is currently using is stored temporarily.

RAM memory can be accessed much faster than data on a hard disk, SDD, or another long-term storage device, which is why RAM capacity is so important for system performance.


Q-13)   LAN stands for __________.

(a)

(b)

(c)

(d)

(e)

Explanation:

LAN stands for local area network. A network is a group of two or more connected computers, and a LAN is a network contained within a small geographic area, usually within the same building. Home WiFi networks and small business networks are common examples of LANs. LANs can also be fairly large, although if they take up multiple buildings, it is usually more accurate to classify them as wide area networks (WAN) or metropolitan area networks (MAN).


Q-14)   IT stands for

(b)

(c)

(d)

(e)

Explanation:

Stands for Information Technology, and is pronounced I.T.

Explanation:

Video Graphics Array VGA is an analogue interface between a PC and monitor that was widely used prior to DVI, HDMI and DisplayPort. VGA was introduced on the IBM PS/2 in 1987, replacing the previous digital CGA and EGA interfaces, which had lower resolution and fewer colours. New LCD monitors may include a VGA port for legacy PCs, and PCs may have a VGA port for legacy monitors. See DVI, HDMI and DisplayPort.
