Question 1

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 2

What is the primary 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 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 best describes what 'Cloud Computing' means?

Accepted Answer

Cloud computing is a model of computing where data, applications, and services are stored and accessed over the internet from remote servers rather than on a local computer or on-premises infrastructure.

Question 5

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 'S' for Secure), which encrypts data during transmission.

Question 6

Which of the following correctly describes the difference between 'Bandwidth' and 'Latency' in network performance?

Accepted Answer

Bandwidth refers to the maximum data transfer rate (measured in Mbps or Gbps) — how much data can be transmitted per unit time. Latency refers to the delay in data transmission (measured in milliseconds) — how long it takes for data to travel from source to destination. Both are critical for network performance but measure different aspects.

Question 7

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, filtering data packets to prevent unauthorized access.

Question 8

What is the maximum size of a standard IPv4 address space in terms of unique IP addresses?

Accepted Answer

IPv4 (Internet Protocol version 4) uses 32-bit addresses, which allows for 2^32 = 4,294,967,296 unique IP addresses. This theoretical maximum is divided into public and private address ranges, with some reserved for special purposes.

Question 9

What does 'RAM' stand for in computer memory terminology?

Accepted Answer

RAM stands for Random Access Memory, which is a type of volatile computer memory that allows data to be read and written in any order (randomly), unlike sequential access memory. It is essential for temporary storage during active computing operations.

Question 10

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. It is a data storage virtualization technology that combines multiple physical disk drives into a single logical unit for the purposes of data redundancy, performance improvement, or both. RAID configurations (RAID 0, 1, 5, 6, 10, etc.) are widely used in servers and enterprise storage systems to ensure data protection and faster access speeds.

Question 11

Which of the following best describes the function of a GPU (Graphics Processing Unit) in modern computing?

Accepted Answer

A GPU is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images. Modern GPUs are used not only for graphics rendering but also for parallel processing tasks like machine learning, cryptocurrency mining, and scientific computing due to their ability to perform thousands of calculations simultaneously.

Question 12

In networking, what does the acronym TCP/IP stand for?

Accepted Answer

TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is the fundamental suite of communication protocols used for transmitting data over the internet and most modern networks. TCP ensures reliable, ordered delivery of data, while IP handles routing and logical addressing.

Question 13

What is the primary purpose of a Firewall in computer network security?

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 (like the internet), filtering packets and blocking unauthorized access while allowing legitimate traffic.

Question 14

Which of the following is the correct full form of BIOS in computer systems?

Accepted Answer

BIOS stands for Basic Input/Output System. It is firmware that initializes hardware during the boot process before the operating system loads. BIOS performs hardware tests (POST - Power-On Self Test) and provides runtime services for operating systems and programs.

Question 15

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

Accepted Answer

RAM (Random Access Memory) is volatile memory that loses all data when power is turned off; it is fast and used for temporary storage during program execution. ROM (Read-Only Memory) is non-volatile memory that retains data even without power; it contains firmware and cannot be easily modified. RAM is larger in capacity but slower than cache; ROM is smaller but permanent.
