1. What is a computer?
A computer is an electronic device that processes and stores data to perform a variety of tasks. It consists of both hardware (physical components) and software (programs that enable the hardware to execute specific operations).
2. What are the basic components of a computer?
The basic components of a computer include the central processing unit (CPU), memory, storage devices (such as hard drives or solid-state drives), input devices (keyboard and mouse), and output devices (monitor or printer).
3. What is an operating system?
An operating system is a software that manages computer hardware and software resources. It provides an interface for users to interact with the computer and ensures that programs run smoothly.
4. What is the difference between hardware and software?
Hardware refers to the physical components of a computer, while software refers to the programs and data that are stored on the hardware.
5. What is a desktop computer?
A desktop computer is a non-portable computer that typically consists of a tower or a case housing the hardware components and a monitor.
6. What is a laptop?
A laptop, also known as a notebook, is a portable computer with a built-in monitor, keyboard, and mouse. It provides flexibility and mobility compared to a desktop computer.
7. What is a smartphone?
A smartphone is a mobile device that combines the functionality of a phone with computer capabilities. It allows users to perform a wide range of tasks, such as calling, texting, browsing the internet, and running applications.
8. What is the internet?
The internet is a global network of interconnected computers that allows the sharing of information and resources. It enables communication, access to websites, online shopping, and much more.
9. What is a web browser?
A web browser is a software application that allows users to access and navigate websites on the internet. Popular browsers include Google Chrome, Mozilla Firefox, and Safari.
10. What is a search engine?
A search engine is a program that searches databases and indexes the internet for specific information based on user queries. Google is the most well-known search engine.
1. What is the primary purpose of an operating system?
a) To provide hardware resources to software applications.
b) To translate high-level programming languages into machine language.
c) To generate random numbers for mathematical calculations.
d) To control and coordinate computer hardware components.
Answer: d) To control and coordinate computer hardware components.
Operating systems are the software that manage computer hardware and software resources and provide services to other software applications.
2. What is the function of a CPU (Central Processing Unit)?
a) To store data and software applications.
b) To process and execute instructions.
c) To display images and videos on the screen.
d) To provide input/output interfaces.
Answer: b) To process and execute instructions.
The CPU is the brain of the computer, responsible for performing calculations, manipulating data, and executing instructions.
3. What is the purpose of RAM (Random Access Memory)?
a) To store permanent data even when the computer is turned off.
b) To provide external storage for large files.
c) To temporarily store data and instructions that the CPU needs for immediate access.
d) To perform complex mathematical calculations.
Answer: c) To temporarily store data and instructions that the CPU needs for immediate access.
RAM is a volatile memory that allows the CPU to quickly access and retrieve data and instructions that are frequently used during computer operations.
4. What is the role of a compiler?
a) To execute programs and produce results.
b) To convert high-level programming language into machine language.
c) To connect computers and facilitate communication.
d) To store and organize files and folders.
Answer: b) To convert high-level programming language into machine language.
A compiler is software that translates programs written in high-level programming languages, such as C++, Java, or Python, into machine language that can be understood and executed by the computer.
5. What is the purpose of a firewall?
a) To protect the computer from physical damage caused by overheating.
b) To filter and block unauthorized access to a computer or network.
c) To boost internet speed and connectivity.
d) To store and manage large amounts of data.
Answer: b) To filter and block unauthorized access to a computer or network.
Firewalls are security mechanisms that monitor and control incoming and outgoing network traffic, protecting the computer from unauthorized access and potential cyber-attacks.
