Computer networks connect devices and computers to share resources, information and services. They can be built on wired or wireless connections and are able to be configured in different network topologies. Nowadays, networks are essential to the business. They allow us to communicate more effectively, collaborate with others and work more efficiently. They also aid in data security and access.

Computer networking is an extensive field that includes the creation as well as the maintenance and construction of communication networks. It is a combination of electrical engineering.

The Internet is the most well-known computer network with billions of users to connect and share the same resources at the same time. The network uses a packet-switching model to channel data traffic through a nearly infinite number of pathways and connections. Each packet contains control information as well user information. Control information includes sources and destinations network addresses along with error detection codes as well as sequencing information. The data portion of a packet contains the payload.

In a typical network a central server stores information and controls access for users to essential resources such as printers, photocopiers, and other files. The server is protected by firewalls and a multifactor authentication to ensure that only authorized users can access the network. The centralization of data on servers makes it easier for administrators and security policy enforcers to perform regular backups. Employees can also access corporate services and applications, regardless of their location — such as video-calling software as well as document-sharing.
