The server and the client communicate as follows in this server-based network: The client first sends a request to the server. The server evaluates the request and then transmits the response. In this model, the client always connects to the server, never the other way around.

Here’s a real-life example: In a typical office, every workstation has its own computer. Without a network of computers, it would be very difficult for a team to work on a project since there would be no common place to share or store digital documents and information, and team members would not be able to share certain applications.

In addition, many offices only have one printer or a few printers that are shared by everyone. Without a network, the IT department would have to connect every single computer to the printer, which is difficult to implement from a technical standpoint.

A protocol is a set of rules or algorithms which define the way how two entities can communicate across the network and there exists a different protocol defined at each layer of the OSI model. A few such protocols are TCP, IP, UDP, ARP, DHCP, FTP, and so on.

IP Address: An IP address is a unique numerical identifier that is assigned to every device on a network. IP addresses are used to identify devices and enable communication between them.

Since the devices are connected to the router as clients, they are part of the network and can use the same resource as the server, namely the Internet.

Bus Topology: In bus topology all devices are connected to a single central cable called a bus. Data is sent along this cable and all devices share the same connection. Simple and cheap to set up but 男同网 if the main cable fails the whole network goes down.

Computer network play a important role in modern life. Here are some key benefits of computer networks:

Network addresses In addition, it is necessary to ensure that the transmitter and receiver can be correctly identified. Network addresses are used for this purpose. In computer networks, each computer typically has an IP address, similar to a telephone number, that uniquely identifies the computer.

Resource sharing. Enterprises of all sizes can use a computer network to share resources and critical assets. Resources for sharing can include printers, files, scanners and photocopy machines.

Application layer. Security protocols, such as Transport Layer Security, operate at this layer and play an integral part in ensuring network security. This is the abstraction layer that communicates directly with applications and defines how high-level apps should access the network to start a data transfer.
