Q-1) What does ‘C’ represent in MICR?
(a)
(b)
(c)
(d)
(e)
Magnetic ink individual reputation (MICR) is an era used in the main to perceive and system checks.
It is known as a magnetic ink individual reputation line in connection with the print era this is used to allow a system to read, system, and file information. The MICR is a tool that could realize human readable characters revealed on files which includes cheques with the use of a unique magnetic ink.
The reader reads those characters with the aid of using analyzing their shapes.
The abbreviation MICR stands for Magnetic Ink Character Recognition.
Q-2) __________ are often delivered to a PC through an email attachment and are often designed to do harm.
(a)
(b)
(c)
(d)
(e)
Computer viruses are often delivered to a PC through an email attachment and are often designed to do harm.
Viruses spread through opening an email attachment that is infected, visiting websites that are infected, connecting USB drives that are infected, and even viewing infected advertisements.
Q-3) ‘C’ in CPU denotes _____________.
(a)
(b)
(c)
(d)
(e)
The CPU of a PC consists of a single microprocessor, while the CPU of a more powerful mainframe consists of multiple processing devices, and in some cases, hundreds of them.
The term “processor” is often used to refer to a CPU.
Q-4) BIT stands for
(a)
(b)
(c)
(d)
(e)
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)
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)
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)
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)
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)
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)
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.
