Information and Communication Technology ICT

A supercomputer is often referred to as a high-performance computer due to its ability to process data and perform computations at extremely high speeds.

Input, processing, output, and storage are collectively referred to as the information processing cycle, which describes the basic functions of a computer system.

Information is the processed data that a computer outputs, making it meaningful and useful for users.

Tally is not considered system software; it is an application software used for accounting purposes.

A Local Area Network (LAN) is suitable for connecting computers within a limited area such as an office building.

An interpreter translates program instructions into machine language one line at a time, unlike a compiler which does it all at once.

A program is a sequence of instructions written in a computer language to perform a specific task.

USB stands for Universal Serial Bus, a standard for connecting devices to a computer.

.jpeg is an image file extension and is not suitable for MS-Word documents, which typically use .doc or .docx.

ICT stands for Information and Communications Technology, which encompasses all technologies for communication and information processing.

ICT stands for Information and Communication Technology, which refers to technologies that provide access to information through telecommunications.

Mobile phones transmit information using radio waves, which are a type of electromagnetic radiation.

The Windows operating system is an example of software, specifically system software that manages hardware and software resources.

Word processing is primarily used for creating and editing text documents such as letters, reports, and books.

The main purpose of ICT is to facilitate the storage, processing, and transportation of information using electronic devices and telecommunications.

Processed data in computers is called information, which is data that has been organized or structured in a meaningful way.

Telecommunication refers to the transmission of information over significant distances using electronic means such as telephones, radios, and computers.

A keyboard is an example of input hardware, as it allows users to enter data and commands into a computer.

The primary role of output hardware is to display or present processed data to the user in a perceivable form, such as through monitors or printers.

Software is the component of a Computer-Based Information System (CBIS) that instructs hardware on how to process data.

System software is mainly responsible for managing and running hardware components and providing a platform for running application software.

Electromagnetic waves are commonly used for communication in mobile phones and radios, as they can travel long distances and carry information efficiently.

A transducer in a communication system is used to convert signals from one form of energy to another, such as converting sound waves to electrical signals.

The main role of the receiver in a telephone system is to convert electrical signals back into sound, allowing the user to hear the transmitted voice.

Electromagnetic radio waves are the primary method used to transmit data over long distances due to their ability to travel through the atmosphere and space.

A microphone is the device that converts sound waves into electrical impulses in a radio station, allowing sound to be transmitted or recorded.

In a fax machine, scanned information is typically transmitted through telephone lines, which carry the data to the receiving fax machine.

Visible light waves can transmit information faster than radio or microwaves because they have a much higher frequency, allowing for a greater data transfer rate.

The purpose of the cladding in an optical fiber is to reflect the light back into the core, ensuring that the light signal is transmitted efficiently with minimal loss.

The CPU (Central Processing Unit) is considered the "brain" of a computer system because it performs most of the processing inside the computer.

Data in RAM is volatile, meaning it is lost when the computer is turned off because RAM requires power to retain data.

ROM (Read-Only Memory) stores data permanently and is not easily changed; it contains firmware or software that is essential for booting up a computer.

A USB drive is an example of secondary storage, which is used for long-term storage of data and is non-volatile.

Audio and video cassettes use magnetism to store sound and video by altering the magnetic properties of a tape coated with magnetic material.

A microphone converts sound waves into electrical pulses in an audio cassette recorder, allowing the sound to be recorded onto the tape.

A floppy disk is described as a flexible plastic wafer coated with magnetic material, used for data storage in older computer systems.

Data on a Compact Disc (CD) is read by a laser beam that reflects off pits and lands on the disc's surface, which represent binary data.

The pits and lands on a CD represent binary data, where pits and lands correspond to the 0s and 1s of digital information.

A flash drive is a small, portable storage device that can hold large amounts of data using integrated circuits (ICs).

The main purpose of word processing is to create and edit text documents, such as letters, reports, and books.

The first hard drive transported by IBM, known as the IBM 350, had a storage capacity of 5 MB.

Google Chrome is an example of a web browser, which is used to access and view websites on the internet.

HTTP stands for Hyper Text Transfer Protocol, which is a protocol used for transmitting hypertext requests and information on the internet.

A key advantage of using e-mail is fast communication across the world, allowing messages to be sent and received almost instantaneously.
