    What is ESD?

    • A.

      Electrical System Delivery

    • B.

      Electro-Static Discharge

    • C.

      Enumerated System - Decimal

    • D.

      Electronic Sensing Device

    Correct Answer
    B. Electro-Static Discharge
    Explanation
    ESD stands for Electro-Static Discharge. It refers to the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or a dielectric breakdown. ESD can damage electronic devices, components, and circuits, leading to malfunctions or complete failure. It is a significant concern in industries such as electronics manufacturing, where sensitive components are handled. Proper ESD control measures, such as grounding, use of antistatic materials, and ESD-safe workstations, are crucial to prevent ESD-related damage.

    The form factor of a motherboard refers to

    • A.

      The chemical composition of the board, including hazardous materials and "green" components

    • B.

      The performance characteristics including CPU speed, bus size, memory capacity, and memory speed

    • C.

      The specific voltages that are accepted by the CPU and chipset

    • D.

      The dimensions of the board, the mounting hole arrangement, and the location of components and I/O port connectors.

    Correct Answer
    D. The dimensions of the board, the mounting hole arrangement, and the location of components and I/O port connectors.
    Explanation
    The form factor of a motherboard refers to the dimensions of the board, the mounting hole arrangement, and the location of components and I/O port connectors. This means that it determines the physical size and layout of the motherboard, which is important for compatibility with computer cases and other components. It does not refer to the chemical composition, performance characteristics, or specific voltages of the board.

  • 5. 

    Serial communication means

    • A.

      Transmitting one byte at a time

    • B.

      Transmitting one bit at a time

    • C.

      Transmitting one nibble at a time

    • D.

      Transmitting one word at a time

    Correct Answer
    B. Transmitting one bit at a time
    Explanation
    Serial communication refers to the process of transmitting data sequentially, one bit at a time. This means that the data is sent in a continuous stream, with each bit being transmitted one after the other. This method is commonly used in various communication protocols, such as RS-232, where data is transmitted over a single wire. By sending data in this manner, it allows for efficient and reliable communication between devices, even over long distances.

  • 6. 

    At their core, computers recognize only what number system?

    • A.

      Binary

    • B.

      Hexadecimal

    • C.

      Decimal

    • D.

      Octal

    Correct Answer
    A. Binary
    Explanation
    Computers recognize only the binary number system at their core. Binary is a base-2 number system that uses only two digits, 0 and 1. This is because computers are made up of electronic circuits that can be in either an "on" or "off" state, which can be represented by 0 or 1 respectively. All data and instructions are stored and processed in binary form within a computer's hardware. Other number systems like hexadecimal, decimal, and octal are often used for human convenience and programming purposes, but at their core, computers operate in binary.

    In a PC with an Intel chipset, which component interfaces the audio codec and BIOS?

    • A.

      Northbridge

    • B.

      GMCH

    • C.

      ICH

    • D.

      Super I/O

    Correct Answer
    C. ICH
    Explanation
    The ICH (Input/Output Controller Hub) interfaces the audio codec and BIOS in a PC with an Intel chipset. The ICH is responsible for managing various input/output functions, including audio, and acts as a bridge between the CPU and other components such as the BIOS. It handles communication between the audio codec, which processes audio signals, and the BIOS, which provides low-level software support for the PC's hardware. This allows the audio codec and BIOS to communicate and work together seamlessly.

  • 8. 

    A byte is composed of:

    • A.

      4 bits

    • B.

      1 bit

    • C.

      2 words

    • D.

      8 bits

    Correct Answer
    D. 8 bits
    Explanation
    A byte is composed of 8 bits. In computer systems, a bit is the smallest unit of data and can have a value of either 0 or 1. A byte, on the other hand, is a unit of storage that is typically used to represent a single character. It is composed of 8 bits, allowing it to represent a total of 256 different values (2^8). Therefore, the correct answer is 8 bits.

    The following are examples of input devices:

    • A.

      Memory, CPU, chipset

    • B.

      Keyboard, mouse, microphone

    • C.

      BIOS, audio codec, ICH

    • D.

      Monitor, printer, speaker

    Correct Answer
    B. Keyboard, mouse, microphone
    Explanation
    The correct answer is keyboard, mouse, microphone. These devices are examples of input devices because they allow the user to input data or commands into the computer system. The keyboard allows the user to type text or enter commands, the mouse allows for pointing and clicking on screen elements, and the microphone allows for audio input. These devices are essential for interacting with the computer and providing input for various tasks and applications.

    The hard drive acts as what type of device?

    • A.

      Input

    • B.

      Output

    • C.

      Both input and output

    • D.

      Neither input or output

    Correct Answer
    C. Both input and output
    Explanation
    The hard drive acts as both an input and output device because it is used to store and retrieve data. It receives data from the computer's processor and other input devices, such as keyboards or mice, and stores it for later use. It also outputs data by retrieving and sending it back to the processor or other output devices, such as monitors or printers. Therefore, the hard drive plays a dual role in both receiving and sending data, making it an input and output device.
