8 bits make up a byte. This is a fundamental unit of digital information in computing and telecommunications.

CRT stands for Cathode Ray Tube, which is a technology used in traditional television and computer monitor displays. The other options are incorrect expansions of the acronym.

BCD stands for 'Binary Coded Decimal,' which is a class of binary encodings for decimal numbers where each digit is represented by its own binary sequence.

The first page of a website is commonly referred to as the 'Homepage.' It serves as the main entry point and starting page for visitors to a website.

1 GB (gigabyte) is commonly considered as 1,000,000,000 bytes (1 billion bytes) in the decimal (SI) system, which is the standard in most contexts outside of computer memory (where 1 GB can mean 1,073,741,824 bytes).

The standard 4K resolution used in digital cinema is 4096×2160 pixels, which is answer D. The other options do not match the standard 4K specification.

1 Byte is equal to 8 bits. This is a standard unit of digital information in computing and telecommunications.

HTTP stands for Hypertext Transfer Protocol, which is the foundation of data communication for the World Wide Web. Option B is the only correct expansion of the acronym HTTP.

The first boot sector virus is known as 'Brain,' which was created in 1986 by two brothers from Pakistan. It infected the boot sector of storage media, making it the earliest known example of this type of virus.

Google was officially founded by Larry Page and Sergey Brin on September 4, 1998, in Menlo Park, California. This is the widely recognized date of the company's incorporation.

Microsoft was founded by Bill Gates and Paul Allen in 1975. This is a well-documented fact in the history of technology companies.

1 Byte is equal to 8 bits. This is a standard unit of digital information in computing and telecommunications.

8 bits make up a byte. This is a standard unit of digital information in computing and telecommunications.

BCC stands for 'Blind Carbon Copy,' which is an email feature that allows the sender to conceal the recipient entered in the BCC field from the other recipients.

CRT stands for 'Cathode Ray Tube,' which is a technology used in traditional computer monitors and television screens. The other options are incorrect expansions of the acronym.

The word 'virus' is derived from Latin, where it originally meant 'poison' or 'slimy liquid.' It is not originally an English or Greek word.

1 KB (Kilobyte) is equal to 1024 bytes. This is a standard unit of digital information storage in computing, where 1 KB = 1024 bytes.

ALU stands for Arithmetic Logic Unit, which is a digital circuit used to perform arithmetic and logic operations in computers.

BCD stands for 'Binary Coded Decimal,' which is a class of binary encodings of decimal numbers where each decimal digit is represented by a fixed number of binary digits, usually four or eight.

The abacus is considered the earliest known calculating device, used for basic arithmetic operations such as addition, subtraction, multiplication, and division. It is a manual tool and represents the beginning of computational devices in human history.

CSS stands for 'Cascading Style Sheets.' None of the provided options correctly state the full form. Option B only says 'Cascading,' which is incomplete. The correct full form is 'Cascading Style Sheets,' so the options should be corrected to reflect this. Since none of the options are fully correct, the best correction is to update the options and correct answer accordingly.

ACL stands for Access Control List, which is used in computer systems and networking to define permissions for users or processes. It specifies which users or system processes are granted access to objects, as well as what operations are allowed.

1 GB (gigabyte) is equal to 1,000,000,000 bytes (1 billion bytes) in the decimal system, which is commonly used for storage devices. Therefore, 5 GB is 5 billion bytes.

IBM introduced the IBM Personal Computer (IBM PC) in 1981, which became widely recognized as the first computer designed for home and personal use by a major company.

A nibble is equal to 4 bits. Therefore, 4 nibbles equal 16 bits. Since 1 byte is 8 bits, 16 bits equal 2 bytes.
