Question 1

Which of the following is the correct full form of 'HTTP' used in web addresses?

Accepted Answer

HTTP stands for HyperText Transfer Protocol. It is the foundational protocol used for transferring data across the World Wide Web. HTTPS is its secure version with an additional 'S' for Security.

Question 2

What does 'URL' stand for in internet terminology?

Accepted Answer

A URL is the web address that identifies the location of a resource on the internet. It is the string of characters you type into a browser's address bar to access websites and web pages.

Question 3

What does the acronym 'HTTP' stand for in web technology?

Accepted Answer

HTTP is the foundational protocol used for transferring data across the World Wide Web. It defines how messages are formatted and transmitted between web browsers (clients) and web servers.

Question 4

Which of the following is the correct full form of 'RAM' in computer memory?

Accepted Answer

RAM is a type of volatile computer memory that temporarily stores data and programs currently being used by the CPU. It is called 'random access' because any memory location can be accessed directly in any order.

Question 5

Which of the following best describes what 'bandwidth' means in the context of internet connectivity?

Accepted Answer

Bandwidth refers to the maximum rate of data transfer across a network connection, typically measured in bits per second (bps). Higher bandwidth allows faster data transmission and better performance for streaming, downloads, and browsing.

Question 6

What is the primary function of an 'Operating System' (OS) in a computer?

Accepted Answer

An Operating System is system software that manages hardware resources and provides services to application programs. It acts as an intermediary between the user and the computer hardware, enabling communication and resource allocation.

Question 7

What is the maximum size of a standard IPv4 address in bits?

Accepted Answer

An IPv4 (Internet Protocol version 4) address is composed of 32 bits, divided into 4 octets of 8 bits each, represented in dotted decimal notation (e.g., 192.168.1.1).

Question 8

Which of the following is NOT a type of computer memory?

Accepted Answer

Computer memory types include RAM (Random Access Memory), ROM (Read-Only Memory), Cache Memory, and Virtual Memory. GPU (Graphics Processing Unit) is a processor component, not a memory type.

Question 9

What does the acronym 'URL' stand for in web terminology?

Accepted Answer

URL stands for Uniform Resource Locator. It is the web address used to identify and locate resources on the internet, such as web pages, images, and files.

Question 10

Which of the following best describes the function of a 'Firewall' in computer networks?

Accepted Answer

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between trusted internal networks and untrusted external networks.

Question 11

In networking, what does the acronym 'TCP/IP' stand for, and which layer of the OSI model does it primarily operate at?

Accepted Answer

TCP/IP stands for Transmission Control Protocol/Internet Protocol, and it primarily operates at the Transport (Layer 4) and Network (Layer 3) layers of the OSI model, forming the foundation of modern internet communication.

Question 12

Which of the following best describes the function of 'Cache Memory' in a computer system?

Accepted Answer

Cache memory is a small, fast memory located between the CPU and main memory (RAM) that stores frequently accessed data and instructions to reduce access time and improve processing speed.

Question 13

Which of the following protocols is used to establish a secure encrypted connection between a web browser and a web server, and is indicated by 'https://' in the URL?

Accepted Answer

TLS (Transport Layer Security) and its predecessor SSL (Secure Sockets Layer) are cryptographic protocols that encrypt data transmitted between a client and server. HTTPS (HTTP Secure) uses TLS/SSL to secure web communications. TLS 1.3 is the current standard as of 2024.

Question 14

Which of the following is the correct full form of 'RAID' in the context of computer storage systems?

Accepted Answer

RAID stands for Redundant Array of Independent Disks, a data storage technology that combines multiple disk drives for improved performance and fault tolerance.

Question 15

In cybersecurity, what is the primary purpose of a 'Firewall' in a computer network?

Accepted Answer

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules, acting as a barrier between trusted and untrusted networks.

Question 16

Which of the following correctly describes the difference between 'RAM' and 'ROM' in computer memory systems?

Accepted Answer

RAM (Random Access Memory) is volatile, fast, and used for temporary data during processing, while ROM (Read-Only Memory) is non-volatile, slower, and stores permanent firmware/boot instructions that cannot be easily modified.
