Explanation
A peripheral refers to any device or hardware that is connected to a computer. It includes external devices such as keyboards, mice, printers, scanners, and monitors, as well as internal components like hard drives and graphics cards. These peripherals provide additional functionality and allow users to interact with the computer system. Therefore, anything connected to a computer, whether internally or externally, is considered a peripheral.

Explanation
A port is a hardware interface that allows users to connect external output devices to the computer system. It acts as a communication channel between the computer and the external device, enabling data transfer and interaction. With the help of ports, users can connect devices such as monitors, printers, speakers, and USB drives to their computers, expanding the functionality and capabilities of the system.

Explanation
The microprocessor is considered the brain of the computer because it is responsible for executing instructions and performing calculations. It is a small chip that acts as the central processing unit (CPU), which controls and coordinates all the activities of the computer system. The microprocessor carries out tasks such as fetching, decoding, and executing instructions, as well as managing data flow and controlling the timing of operations. Without the microprocessor, a computer would not be able to function as it is responsible for all the essential operations and calculations that take place within the system.

Explanation
Flash memory is a type of storage that uses a chip to hold information. It is commonly used in devices such as smartphones, tablets, and digital cameras. Flash memory is non-volatile, meaning it retains data even when power is turned off. On the other hand, a flash drive is a portable storage device that uses flash memory to store data. While both flash memory and flash drives use chips to hold information, flash memory refers to the technology itself, whereas a flash drive is a specific type of device that utilizes flash memory.

Explanation
Optical disks are storage devices that use lasers to read and write information. They are commonly used for storing large amounts of data, such as music, videos, and software. The laser beam interacts with the surface of the disk, creating pits and bumps that represent the data. When the laser reads the disk, it detects the changes in the surface and converts them back into digital information. Optical disks are known for their durability, portability, and ability to store data for long periods of time.

Explanation
A network is a group of computers that are connected to each other. This allows them to share resources and information, such as files, printers, and internet access. Networks can be local, connecting computers within a small area like an office or home, or they can be wide area networks (WANs), connecting computers across larger distances, such as different cities or countries. By connecting computers in a network, users can communicate with each other, collaborate on projects, and access shared resources more efficiently.

Explanation
The correct answer is input device output device. This is because information is entered into a computer through an input device, such as a keyboard or mouse, and then it is processed and displayed or produced through an output device, such as a monitor or printer. Both input and output devices are necessary for the functioning of a computer system.

Explanation
A LAN, or local area network, is a connected group of computers that are close to each other. This network allows for the sharing of resources such as files, printers, and internet access within a limited geographical area, such as a home, office, or school. LANs are typically faster and more secure than wide area networks (WANs) because they cover a smaller area and are privately owned and controlled.

Explanation
A network topology refers to the physical or logical layout of computers and devices in a network. It defines how the nodes are connected and the flow of data between them. Wide area network (WAN) refers to a network that spans a large geographical area, connecting multiple local area networks (LANs) together. Therefore, the correct answer is network topology and WAN, as both terms are relevant to the arrangement of computers in a network. The options wide area network and wide area are incorrect as they do not specifically refer to the arrangement of computers in a network.

Explanation
A server is a computer or system that manages the flow of information on a network. It acts as a central hub, receiving requests and delivering responses to other devices connected to the network. Servers are responsible for storing and distributing data, managing user access, and facilitating communication between devices. They play a crucial role in ensuring the efficient and secure operation of a network.
