Flowcharts offer several advantages: Clarity: They make complex processes easier to understand by visually representing them. Problem-solving: They help in identifying inefficiencies, bottlenecks, or errors in a process. Communication: Flowcharts facilitate clear communication among team members by presenting a common visual understanding. Documentation: They provide a useful record of processes, which can be reviewed or … Read more
The Application Layer is the topmost layer in the OSI model and interacts directly with end-user applications. It provides services like email, file transfer, and network management, enabling applications to communicate over the network.

Star topology: All devices connect to a central hub or switch. It is easy to set up and maintain but can be disrupted if the central hub fails. Ring topology: Devices are connected in a circular fashion, and data travels in one direction. It is efficient but can be vulnerable to failure if any device … Read more
A peer-to-peer network allows devices to act as both clients and servers, sharing resources directly with each other. Its limitations include less centralized control, reduced security, and scalability issues compared to a client/server network, where dedicated servers manage resources and security.

Asynchronous transmission sends data at irregular intervals, using start and stop bits to mark data boundaries (used in lower-speed devices like keyboards). Synchronous transmission sends data in a continuous stream, synchronized with a clock signal (used in higher-speed communication, like Ethernet).

A switch intelligently directs data to the specific device it is intended for, reducing collisions and improving network efficiency. A hub, on the other hand, broadcasts data to all connected devices, leading to more network traffic and potential collisions.

Start and stop bits are used in serial communication to signal the beginning and end of data transmission. A start bit marks the beginning of data transmission, and stop bits signal the end of the data frame, ensuring that the data is received correctly.

Simplex: Data flows in one direction only (e.g., keyboard to computer). Half-duplex: Data flows in both directions, but not simultaneously (e.g., walkie-talkies). Full-duplex: Data flows in both directions simultaneously (e.g., telephone conversation). Related Questions: What is the function and significance of Napier’s Bone in early computing?
