ITF Concepts and Terminology 1 — Questions and Answers
Question 1: Which of the following is considered the "brain" of the computer?
- RAM
- CPU (Correct answer)
- Hard drive
- Motherboard
Correct answer: CPU
The Central Processing Unit (CPU) is often referred to as the 'brain' of the computer because it performs most of the processing inside the computer. It executes instructions, performs calculations, and manages the flow of information, making it responsible for carrying out all the commands and operations that make a computer function. Without the CPU, a computer cannot run programs or process data, making it the core component.
Question 2: Which type of software is primarily used to browse the internet?
- Word processor
- Web browser (Correct answer)
- Spreadsheet software
- Video editing software
Correct answer: Web browser
A web browser is a software application specifically designed to access and display information on the World Wide Web. It allows users to navigate websites, view web pages, and interact with online content by interpreting HTML and other web technologies. Examples include Chrome, Firefox, and Safari, all serving the primary function of connecting users to the internet and rendering web content.
Question 3: What is the primary function of RAM (Random Access Memory) in a computer?
- Store data permanently
- Process instructions from programs
- Provide temporary storage for data that is actively used (Correct answer)
- Control the computer's power supply
Correct answer: Provide temporary storage for data that is actively used
RAM (Random Access Memory) serves as a computer's short-term memory, providing fast, temporary storage for data and programs that the CPU is actively using. When you open an application or file, it's loaded into RAM for quick access, allowing the computer to perform tasks efficiently without constantly accessing slower permanent storage. Unlike a hard drive, data in RAM is volatile and is lost when the computer is turned off.
Question 4: Which of the following is an example of system software?
- Microsoft Word
- Adobe Photoshop
- Microsoft Windows (Correct answer)
- Google Chrome
Correct answer: Microsoft Windows
System software is a type of computer program designed to run a computer's hardware and application programs, acting as an intermediary between the user and the hardware. Microsoft Windows is an operating system, which is a prime example of system software, as it manages all the computer's resources and provides a platform for other software to run. Application software like Word or Photoshop runs on top of the operating system.
Question 5: Which of these best describes the function of a file extension?
- Identifies the file format and helps determine which program can open it (Correct answer)
- Increases the file size to enhance its performance
- Makes files more secure by encrypting them
- Prevents files from being deleted
Correct answer: Identifies the file format and helps determine which program can open it
File extensions are suffixes (like .txt or .pdf) appended to file names that indicate the file's format. This information is crucial for the operating system to identify the file type and determine which software program is capable of opening and processing its content. Without extensions, the system wouldn't know how to handle the file.
