Introduction to Computer Science Questions and Answers
- 1.
The Miss Porters Network is a
- A.
MAN
- B.
SAN
- C.
LAN
- D.
WAN
Correct Answer
C. LANExplanation
LAN stands for Local Area Network, which is a network that connects devices within a limited area such as a home, office, or building. The Miss Porters Network, based on the given information, is most likely a local area network as it is not specified to be a wide area network (WAN) or a metropolitan area network (MAN). A LAN would be sufficient for connecting devices within a single location. Therefore, LAN is the most appropriate answer.Rate this question:

Which is considered to be the computer's short-term memory?
- A.
REM
- B.
ROM
- C.
RAM
- D.
RIM
Correct Answer
C. RAMExplanation
RAM (Random Access Memory) is considered to be the computer's short-term memory. It is a type of computer memory that is used to store data that is currently being used or processed by the computer. Unlike ROM (Read-Only Memory) which is non-volatile and cannot be modified, RAM is volatile and can be read from and written to by the computer. It allows for quick access to data, enabling the computer to perform tasks efficiently. Therefore, RAM is the correct answer in this case.Rate this question:

What are the four major components of a computer?
- A.
Input Devices, CPU, Storage, Output Devices
- B.
Input Devices, Processing Unit, Storage, Output Devices
- C.
Motherboard, Processing Unit, Storage, Output Devices
- D.
Input Devices, Processing Unit, Memory, Output Devices
Correct Answer
A. Input Devices, CPU, Storage, Output DevicesExplanation
Input Devices: These include peripherals like keyboards, mice, and scanners that allow users to enter data into the computer.
CPU (Central Processing Unit): Often referred to as the brain of the computer, the CPU processes instructions from programs and performs calculations.
Storage: This includes both primary storage (RAM) and secondary storage (hard drives, SSDs) for saving data.
Output Devices: These include monitors, printers, and speakers that allow the computer to communicate information to the user.Rate this question:

Which one has two examples of output devices?
- A.
Monitor and scanner
- B.
Speaker and keyboard
- C.
Printer and scanner
- D.
Speaker and printer
Correct Answer
D. Speaker and printerExplanation
The question asks for a pair of examples of output devices. An output device is any hardware component that receives data from a computer and presents it to the user in a human-readable form. The options "monitor and scanner" and "keyboard and speaker" do not both consist of output devices. However, "printer and scanner" and "speaker and printer" both contain two examples of output devices. Therefore, the correct answer is "speaker and printer."Rate this question:

What is the brain of the computer?
- A.
Motherboard
- B.
Memory
- C.
CPU
- D.
NIC
Correct Answer
C. CPUExplanation
The brain of a computer is the central processing unit (CPU). It is responsible for executing instructions, performing calculations, and coordinating the activities of all the other hardware components. The CPU processes data and controls the flow of information within the computer system. It is often referred to as the brain because, like a brain, it is the central control unit that performs the majority of the computing tasks.Rate this question:

Application software_________________________________
- A.
Tells the computer components what to do
- B.
Let's the computer interact with the user
- C.
Let's the user perform a task.
- D.
Is encoded on a piece of hardware.
Correct Answer
C. Let's the user perform a task.Explanation
Application software refers to the programs and software applications that are designed to perform specific tasks or functions for the user. Unlike system software, which manages and controls the computer components, application software allows the user to interact with the computer and perform various tasks such as word processing, spreadsheet calculations, graphic design, and more. It provides a user-friendly interface and tools that enable the user to accomplish specific goals or complete specific tasks efficiently and effectively.Rate this question:

What allows multiple programs to run on a computer?
- A.
NIC
- B.
OS
- C.
API
- D.
GUI
Correct Answer
B. OSExplanation
The correct answer is OS. The operating system (OS) allows multiple programs to run on a computer by managing system resources such as memory, processing power, and input/output devices. It provides an interface between the hardware and software, allowing programs to communicate with the computer's hardware and access its resources. The OS also schedules and prioritizes tasks, ensuring that multiple programs can run simultaneously without interfering with each other.Rate this question:

Everything physical in a computer is attached to the...
- A.
Hard drive
- B.
CPU
- C.
Memory
- D.
Motherboard
Correct Answer
D. MotherboardExplanation
The motherboard is the main circuit board of a computer, which connects and allows communication between all the physical components. It provides power and data connections to the CPU, memory, and other devices such as the hard drive. Therefore, everything physical in a computer, including the hard drive, CPU, and memory, is attached to the motherboard.Rate this question:

Information that is broken down into small chunks before it is sent to another computer are called...
- A.
Letters
- B.
Packets
- C.
Messages
- D.
Packages
Correct Answer
B. PacketsExplanation
When information is broken down into small chunks before being sent to another computer, these chunks are called packets. Each packet contains a portion of the original data along with additional information such as the source and destination addresses. These packets are then transmitted individually and reassembled at the receiving computer to recreate the original information. This process allows for efficient and reliable communication over networks.Rate this question:

What type of software is free to try but then you have to buy?
- A.
Commercial
- B.
Shareware
- C.
Opensource
- D.
Microsoft Word

Shareware is a type of software that is initially free to try but requires a purchase to continue using it. This model allows users to test the software's functionality and features before deciding to buy it. It is a common practice in the software industry, where developers offer limited or trial versions of their software to attract potential customers. Shareware typically offers a time-limited trial or restricts certain advanced features until a license is purchased.Rate this question:
