Question 1

What does 'GB' stand for as a unit of digital storage?

Accepted Answer

GB is a standard unit of digital information storage in computing. It represents a large amount of data and is commonly used to measure hard drive capacity, RAM, and file sizes.

Question 2

What is the full form of 'URL' used in internet and web browsing?

Accepted Answer

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

Question 3

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

Accepted Answer

An Operating System (OS) is system software that manages computer hardware and software resources, providing services to applications and enabling user interaction with the computer.

Question 4

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 typically measured in bits per second (bps), kilobits per second (kbps), or megabits per second (Mbps).

Question 5

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

Accepted Answer

RAM is a type of computer memory that allows quick read and write access to data. It is volatile memory, meaning data is lost when power is turned off.

Question 6

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

Accepted Answer

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

Question 7

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 8

What does 'URL' stand for in internet terminology?

Accepted Answer

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

Question 9

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

Accepted Answer

HTTP stands for HyperText Transfer Protocol, which 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 10

What is the maximum file size limit for a standard FAT32 file system?

Accepted Answer

FAT32 (File Allocation Table 32-bit) is an older file system that has a maximum individual file size limit of 4 GB. This limitation was a significant constraint compared to modern file systems like NTFS, which support much larger files.

Question 11

What does the acronym 'URL' stand for in the context of web addresses?

Accepted Answer

URL stands for Uniform Resource Locator. It is the web address used to identify and locate resources on the internet. A URL typically consists of a protocol (http/https), domain name, and path to a specific resource.

Question 12

What does 'URL' stand for in the context of web browsing?

Accepted Answer

URL stands for Uniform Resource Locator. It is the web address that identifies the location of a resource on the internet. A typical URL includes the protocol (http/https), domain name, and path to the specific resource.

Question 13

Which of the following is the correct definition of 'Firewall' in computer 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).

Question 14

What is the primary function of a 'Cache Memory' in a computer system?

Accepted Answer

Cache memory is a small, high-speed memory located between the CPU and main RAM. Its primary function is to store frequently accessed data and instructions to reduce the time the CPU spends waiting for data from slower main memory (RAM).

Question 15

Which of the following best describes the term 'Bandwidth' 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), kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second (Gbps). Higher bandwidth allows faster data transmission.

Question 16

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), filtering data packets and blocking unauthorized access.

Question 17

What does the term 'RAM' stand for in computer terminology?

Accepted Answer

RAM stands for Random Access Memory. It is a type of volatile memory that temporarily stores data and programs currently being used by the CPU. Unlike ROM (Read-Only Memory), RAM loses all its contents when the computer is powered off. This is a fundamental and static IT concept.

Question 18

Which of the following protocols is used for secure email transmission and operates on port 465 or 587?

Accepted Answer

SMTPS (Simple Mail Transfer Protocol Secure) and SMTP with STARTTLS are used for secure email transmission. Port 465 is used for implicit SMTPS (SSL/TLS from the start), while port 587 is used for SMTP with STARTTLS (TLS negotiation after connection). Both ensure encrypted email sending from clients to mail servers.

Question 19

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

Accepted Answer

HTTPS stands for HyperText Transfer Protocol Secure. It is the secure version of HTTP, using SSL/TLS encryption for data transmission. HTTP (without S) is the non-secure version. HSTS and HDTP are not standard protocols.

Question 20

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

Accepted Answer

TCP/IP stands for Transmission Control Protocol/Internet Protocol. TCP is a transport layer protocol ensuring reliable, ordered delivery of data packets, while IP is a network layer protocol responsible for routing packets across networks. Together, they form the fundamental suite of protocols used on the Internet.
