Questions and Answers
  • 1. 

    The CPU is a single chip called a microprocessor.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the CPU (Central Processing Unit) is indeed a single chip known as a microprocessor. The microprocessor is responsible for executing instructions and performing calculations in a computer system. It acts as the brain of the computer, handling all the processing tasks.

  • 2. 

    The more RAM a computer has, the faster it can process data.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Having more RAM in a computer allows it to store more data that it can quickly access, which in turn improves the processing speed. When a computer runs out of RAM, it starts using the slower hard drive as virtual memory, resulting in slower performance. Therefore, increasing the amount of RAM in a computer can significantly enhance its processing speed by reducing the need for accessing slower storage devices.

    Rate this question:

  • 3. 

    Data are stored permanently in RAM.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The given statement is incorrect. Data is not stored permanently in RAM (Random Access Memory). RAM is a volatile memory where data is temporarily stored while the computer is running. Once the power is turned off, the data stored in RAM is lost. For permanent storage of data, other non-volatile storage devices like hard drives or solid-state drives are used.

    Rate this question:

  • 4. 

    Speakers allow you to save audio right to your hard drive.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Speakers are output devices that produce sound, they do not have the capability to save audio to a hard drive. Saving audio to a hard drive requires a recording device such as a microphone or a software program that allows audio recording. Therefore, the statement is false.

    Rate this question:

  • 5. 

    A GUI allows users to select words, symbols, or graphics from a desktop.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A GUI (Graphical User Interface) is a type of interface that allows users to interact with a computer system through visual elements such as icons, buttons, and menus. It provides a user-friendly way to navigate and operate a computer system. In this context, the statement is true because a GUI does indeed allow users to select words, symbols, or graphics from a desktop by simply clicking or tapping on them.

    Rate this question:

  • 6. 

    The major difference between a LAN and a WAN is the size of area that the network covers.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A LAN (Local Area Network) is a network that covers a small geographical area such as a home, office, or building, while a WAN (Wide Area Network) covers a larger area such as multiple cities or even countries. Therefore, the statement is true as the main distinction between a LAN and a WAN lies in the size of the area they cover.

    Rate this question:

  • 7. 

    Dial-up connections transmit data at a faster rate than broadband connections.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    This statement is false. Dial-up connections transmit data at a slower rate than broadband connections. Dial-up connections use a standard telephone line to connect to the internet, which has a maximum speed of 56 kilobits per second (Kbps). On the other hand, broadband connections use technologies like DSL, cable, or fiber-optic, which can provide much higher speeds ranging from several megabits per second (Mbps) to gigabits per second (Gbps). Therefore, broadband connections are generally faster than dial-up connections.

      Hard drive

    • C.

      User

    • D.

      CPU

    Correct Answer
    D. CPU
    Explanation
    The CPU, or central processing unit, is often referred to as the "brain" of the computer because it is responsible for executing instructions and performing calculations. It is the main component that carries out the majority of the computer's processing tasks, such as running programs, managing memory, and controlling input and output devices. The CPU plays a crucial role in determining the overall performance and speed of a computer system.

    Rate this question:

  • 10. 

    The computer stores data it is processing in ____________________.

    • A.

      RAM

    • B.

      GUI

    • C.

      GB

    • D.

      CRT

    • E.

      IBM

    Correct Answer
    A. RAM
    Explanation
    RAM stands for Random Access Memory. It is a type of computer memory that is used to store data that is currently being processed by the computer. Unlike other types of memory, such as hard drives or solid-state drives, RAM is volatile, meaning that its contents are lost when the computer is powered off or restarted. RAM allows the computer to quickly access and manipulate data, making it an essential component for efficient computing.

    Rate this question:

  • 11. 

    Which of these is not an input device?

    • A.

      Mouse

    • B.

      Keyboard

    • C.

      Monitor

    • D.

      Scanner

    • E.

      Microphone

    Correct Answer
    C. Monitor
    Explanation
    A monitor is not an input device because it is used to display output from a computer rather than to input data or commands. Input devices are used to provide input to a computer system, such as a mouse, keyboard, scanner, or microphone. A monitor is an output device that allows users to visually see the output of their actions on the computer.

    Rate this question:

  • 12. 

    Which of these is not an output device?

    • A.

      Microphone

    • B.

      Monitor

    • C.

      Printer

    • D.

      Speaker

    Correct Answer
    A. Microphone
    Explanation
    A microphone is not an output device. It is an input device that converts sound into an electrical signal, which can then be processed and transmitted. Output devices, on the other hand, are used to display or produce information or results from a computer system. Examples of output devices include monitors, printers, and speakers, all of which are capable of displaying or producing visual or audio output.

    A _____________ is a hardware component that enables a computer to send and receive signals through telephone lines.

    • A.

      Server

    • B.

      Client

    • C.

      Modem

    • D.

      NIC

    Correct Answer
    C. Modem
    Explanation
    A modem is a hardware component that enables a computer to send and receive signals through telephone lines. It converts digital signals from the computer into analog signals that can be transmitted over telephone lines, and vice versa. This allows the computer to connect to the internet or communicate with other devices over a telephone network.

    Rate this question:

    What special hardware device is used to join two or more LANs?

    • A.

      Router

    • B.

      NIC

    • C.

      WAN

    • D.

      Modem

    Correct Answer
    A. Router
    Explanation
    A router is a special hardware device that is used to join two or more LANs (Local Area Networks). It acts as a central hub, directing network traffic between different LANs and ensuring that data packets are delivered to their intended destinations. Routers use routing tables to determine the most efficient path for data transmission, allowing multiple LANs to be interconnected and enabling communication between devices on different networks. Unlike other options listed, such as NIC (Network Interface Card), WAN (Wide Area Network), or modem, a router specifically serves the purpose of connecting LANs together.

    What does RAM stand for?

    Correct Answer
    Random Access Memory
    Explanation
    RAM stands for Random Access Memory. It is a type of computer memory that allows data to be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. This allows for fast and efficient data storage and retrieval.
