It is the main circuit board of a computer. It contains all the circuits and components that run the computer. 2. It is the computer’s working storage space that holds data, instructions for processing, and processed data (information) waiting to be sent to secondary storage. 3. What type of devices enable the computer to use a peripheral device for which it does not have the necessary connections or circuit boards? 4. It is a type of device that is installed in the back corner of the PC case, next to the motherboard. It converts 120VAC (standard house power) into DC voltages that are used by other components in the PC. 5. Which device is a data pathway between several hardware components inside or outside a computer? 6. It is the main “brain” or “heart” of a computer system. It performs all the instructions and calculations that are needed and manages the flow of information through a computer. 7. It is the main part of a microcomputer, sometimes called the chassis. It includes the following parts: Motherboard, Microprocessor, Memory Chips, Buses, Ports, Expansion Slots, and Cards. 8. It is a type of device that a computer uses lasers to read data on optical media. 9. Which device of a computer accesses data stored on a DVD? 10. It is a magnetic storage device that is installed inside the computer
The Correct Answer and Explanation is:
- Motherboard
The motherboard is the primary circuit board of a computer. It holds all the essential components like the CPU, memory, and storage connectors, and it enables communication between these parts. - RAM (Random Access Memory)
RAM serves as the computer’s temporary storage area. It holds data and instructions that are currently in use, as well as the processed data waiting to be sent to permanent storage like a hard drive. - Adapter Cards
Adapter cards (or expansion cards) are devices that allow a computer to interface with peripheral devices that may not be directly compatible. These cards provide the necessary connections or circuit boards to connect peripherals such as printers, sound systems, or additional displays. - Power Supply Unit (PSU)
The power supply unit is located inside the computer case. It converts the alternating current (AC) from the wall outlet into direct current (DC), which is used by the various components within the computer. - Bus
A bus is a communication pathway used to transfer data between different components of the computer, either internally (like between the CPU and memory) or externally (like between a computer and peripherals). - CPU (Central Processing Unit)
The CPU, also known as the processor, is the heart of the computer. It carries out the instructions of a computer program, performing calculations, managing data, and directing the flow of information. - Computer Case/Chassis
The computer case, or chassis, houses all the key internal components, including the motherboard, processor, memory chips, power supply, and expansion cards. It is the physical enclosure that contains the entire system. - Optical Drive (CD/DVD Drive)
An optical drive is a device that uses lasers to read or write data on optical discs, such as CDs, DVDs, or Blu-ray discs. - DVD Drive
A DVD drive is a type of optical drive specifically designed to access data stored on DVDs. It uses a laser to read and write information to and from the disc. - Hard Disk Drive (HDD)
The hard disk drive is a type of magnetic storage device installed inside the computer. It provides long-term storage for the computer’s data and is typically the primary storage medium for most systems.
