Better Security: Well designed networks are more reliable and give businesses more options for keeping data safe. They come with built-in security features like encryption and access controls to protect sensitive information from cyber threats.

Computer networks, especially those that employ cloud-based technologies, can store massive amounts of data and backups on a centralized remote server that's accessible to everyone, at any given time.

More Storage Space: Suppose if we don't have a cloud storage then we have to store data in physical files that will consume a physical space so computer network provide a storage for storing data.

OSI stands for Open Systems Interconnection. It is a reference model that specifies standards for communications protocols and also the functionalities of each layer.

Ring Topology: In ring topology devices are connected in a circular loop with each device connected to two others. Data travels in one direction (or sometimes both) passing through each device until it reaches its destination. A failure in one device can affect the whole network.

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 if the main cable fails the whole network goes down.

The idea of RZ and the idea of L are combined in manchester encoding. Different encoding techniques are used in data c

Network addresses In addition, it is necessary to ensure that the transmitter and receiver can be correctly identified. Network 男同网 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.

Flexibility. Today's computer networks enable people to use flexible communication and resource-sharing methods based on their needs and preferences. For example, some people might use email or instant messaging to communicate, while others might prefer using an app such as WhatsApp.

FTP: Protocolo por transferência por arquivos que permite o envio e recebimento do arquivos entre dispositivos.

The working of Computer Networks can be simply defined as rules or protocols which help in sending and receiving data via the links which allow Computer networks to communicate. Each device has an IP Address, that helps in identifying a device.

Before the advent of modern networks, communication between different computers and devices was very complicated. Computers were connected using a LAN cable.
