Questions and Answers
What is the primary function of the motherboard in a computer system?
The motherboard connects computer parts together and allows other hardware devices to function and communicate.
Distinguish between RAM and ROM in terms of data storage durability.
RAM is volatile memory that temporarily stores data, while ROM is non-volatile memory that permanently stores information.
Explain the role of a Network Interface Card (NIC) in a computer.
A NIC allows a computer to connect to a wired or wireless network and has a unique Media Access Control (MAC) address.

Study Notes
Hardware Devices
- Hardware is essential for a typical computer system, categorized as internal and external devices.
Input Devices
- Include devices like Mouse, Keyboard, and Camera, which allow users to provide data to the computer.
Output Devices
- Comprise devices such as Monitor, Printer, and Plotter, responsible for delivering information from the computer to the user.
Internal Hardware Devices
-
Internal hardware is crucial for the computer's operation and functionality.
-
Motherboard
- Serves as the central hub connecting various computer parts.
- Facilitates communication and functionality between hardware components.
- Made of non-conductive material with copper or aluminum layers.
-
Random Access Memory (RAM)
- Internal chip for temporary data storage.
- Volatile memory, meaning data is lost when power is off.
- Allows data, files, and portions of the operating system currently in use to be read, written, and changed.
-
Read-only Memory (ROM)
- Permanently stores crucial information that cannot be altered.
- Non-volatile memory, retaining data even when the computer is powered down.
- Can only be read from, ensuring important data is preserved.
-
Network Interface Card (NIC)
- Enables connection to networks, both wired and wireless.
- Each NIC has a hard-coded unique MAC address, distinguishing each device.
- Provides each device with its unique identifier for network communication.
