Question 1

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 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

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 the secure version with an additional 'S' for Security.

Question 4

What does 'CPU' stand for in computing?

Accepted Answer

CPU stands for Central Processing Unit. It is the primary component of a computer that performs most of the processing inside a computer and is often referred to as the 'brain' of the computer.

Question 5

What is the primary function of an 'IP address' in computer networks?

Accepted Answer

An IP address is a unique numerical label assigned to each device connected to a network. It serves to identify and locate devices on the internet and enable communication between them.

Question 6

What does 'URL' stand for in internet terminology?

Accepted Answer

A URL is the web address used to locate and access resources on the internet. It specifies the location of a resource on a computer network and a mechanism for retrieving it.

Question 7

What does 'URL' stand for in web browsing?

Accepted Answer

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

Question 8

Which of the following best describes 'Cloud Computing'?

Accepted Answer

Cloud computing is the delivery of computing services — including servers, storage, databases, and software — over the internet ('the cloud') rather than on local computers or on-premises servers.

Question 9

Which of the following best describes what 'bandwidth' means in computer networks?

Accepted Answer

Bandwidth refers to the maximum rate of data transfer across a network connection. It is measured in bits per second (bps) and determines how much data can be transmitted in a given time period.

Question 10

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 faster than storage drives but loses all data when power is switched off.

Question 11

What does 'RAM' stand for in computer terminology?

Accepted Answer

RAM (Random Access Memory) is a type of volatile computer memory that allows data to be read and written in any order, independent of the physical location of the data in memory. It is essential for temporary storage during active computing operations.

Question 12

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

Accepted Answer

RAM (Random Access Memory) is a type of volatile computer memory that allows data to be read and written in any order, independent of the physical location of the data. It is used for temporary storage during active computing operations.

Question 13

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

Accepted Answer

Cache is a small, fast memory component that stores frequently accessed data and instructions, reducing the time needed to retrieve them from slower main memory (RAM) or storage devices. It acts as a buffer between the CPU and main memory.

Question 14

What is the maximum size limit for a standard IPv4 address in terms of the number of bits?

Accepted Answer

An IPv4 (Internet Protocol version 4) address is composed of 32 bits, divided into four octets (8 bits each), represented in dotted decimal notation (e.g., 192.168.1.1). This 32-bit structure allows for approximately 4.3 billion unique addresses.

Question 15

Which of the following correctly describes the difference between 'Malware' and 'Antivirus' software?

Accepted Answer

Malware is malicious software designed to harm, exploit, or compromise computer systems and user data. Antivirus software is protective software designed to detect, prevent, and remove malware from infected systems.

Question 16

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

Accepted Answer

Computer memory systems include various types such as RAM (Random Access Memory), ROM (Read-Only Memory), Cache Memory, and Virtual Memory. However, not all terms related to storage or processing are classified as 'memory' in the technical sense.

Question 17

What does the term 'HTTP' stand for in the context of the internet?

Accepted Answer

HTTP stands for HyperText Transfer Protocol. It is the foundation of data communication on the World Wide Web, defining how messages are formatted and transmitted between web browsers and servers.

Question 18

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 (like the Internet).

Question 19

What is the primary purpose of 'Encryption' in cybersecurity?

Accepted Answer

Encryption is the process of converting plaintext (readable data) into ciphertext (unreadable code) using mathematical algorithms and keys. Its primary purpose is to ensure confidentiality by making data unreadable to unauthorized users, even if they gain access to it.

Question 20

Which of the following correctly describes the function of a 'Router' in a computer network and distinguishes it from a 'Switch'?

Accepted Answer

A Router operates at Layer 3 (Network Layer) of the OSI model and directs data packets between different networks using IP addresses. A Switch operates at Layer 2 (Data Link Layer) and forwards frames within the same network using MAC addresses. Routers connect different networks; switches connect devices within a network.
