ICT (Information And Communication Technology) Quiz For Grade 7

The correct answer is Information and Communication Technology because ICT encompasses all technologies used to handle telecommunications, broadcast media, audio-visual processing, and network-based control and monitoring functions. This field integrates different types of technology to facilitate communication and information sharing. Understanding ICT is crucial in today's digital age, as it impacts various sectors including education, healthcare, and business. The use of ICT can improve efficiency, productivity, and accessibility of information, making it a vital area of study for students.

The correct answer is Protect against malware because antivirus programs are designed to detect, prevent, and remove malware, which includes viruses, worms, trojans, and other malicious software. These programs scan the computer's files and memory for known malware signatures and monitor system activities for suspicious behavior. By providing real-time protection and regular updates, antivirus software helps safeguard the computer's integrity and data, preventing unauthorized access, data breaches, and system damage caused by malware infections.

The correct answer is Keyboard because a keyboard is an essential input device used to enter data into a computer by typing. It allows users to input text, numbers, and commands into a computer system, facilitating interaction with software applications. Unlike output devices such as monitors or printers, which display or produce information, the keyboard directly feeds data into the computer's processing system. This makes it a fundamental tool for performing a wide range of computing tasks, from word processing to programming.

The correct answer is Process information because the CPU (Central Processing Unit) is the primary component of a computer that performs most of the processing inside a computer. It executes instructions from programs by performing basic arithmetic, logic, control, and input/output operations specified by the instructions. The CPU's performance directly affects the overall speed and efficiency of a computer system. It acts as the brain of the computer, managing and coordinating all the other components to ensure smooth operation and execution of tasks.

The correct answer is CPU because the Central Processing Unit (CPU) is the primary component responsible for interpreting and executing instructions in a computer. Often referred to as the brain of the computer, the CPU performs calculations, logic operations, and manages data flow to and from the computer's memory and peripheral devices. Its performance, determined by factors like clock speed and core count, significantly impacts the overall speed and efficiency of the computer system, influencing how quickly tasks and applications are processed.

The correct answer is Word processor because a word processor is a software application used for the creation, editing, formatting, and printing of documents. Unlike spreadsheets or databases, which are used for numerical data management and storage, a word processor is designed specifically for handling text. It provides various tools for writing and editing, such as spell check, grammar check, and text formatting options. This makes it an indispensable tool for creating written documents like essays, reports, and letters.

The correct answer is Monitor because a monitor is an output device that displays information processed by the computer. It presents data visually, allowing users to see the results of their input and interactions with the computer. Monitors come in various sizes and resolutions, and they are crucial for tasks that require visual feedback, such as graphic design, video editing, and general computer use. Unlike input devices like keyboards or mice, monitors do not send information to the computer but rather show the processed output.

The correct answer is Windows because Windows is one of the most widely used operating systems globally, developed by Microsoft. An operating system (OS) manages the computer hardware and software resources and provides services for computer programs. Windows OS offers a user-friendly interface, broad compatibility with various software applications, and extensive support for hardware devices. Its popularity is due to its ease of use, robust security features, regular updates, and extensive ecosystem of applications and developer tools, making it suitable for both personal and professional use.

The correct answer is WAN because a Wide Area Network (WAN) covers a large geographical area, often spanning cities, countries, or even continents. WANs are used to connect multiple smaller networks, such as Local Area Networks (LANs), enabling communication and resource sharing across vast distances. The internet is the largest example of a WAN. WANs utilize various transmission technologies and media, including fiber optics, satellites, and leased lines, to ensure data can travel over long distances efficiently and securely.

The correct answer is Temporary data storage because RAM (Random Access Memory) serves as the computer's short-term memory, storing data that is actively being used or processed by the CPU. Unlike permanent storage devices like hard drives, RAM is volatile, meaning it loses its data when the computer is turned off. Its primary function is to provide quick read and write access to a storage medium that is faster than the hard drive. This enables the CPU to retrieve and execute instructions rapidly, improving the system's performance and responsiveness.
