Computer networks connect computers and other devices together to share resources, information and services. They can be built on wired or wireless connections, and can be configured in a variety of network topologies. Nowadays, networks are crucial to business. They allow us to communicate more effectively, collaborate with others and perform more efficiently. They also help with access to data and security.

Computer networking is an extensive field that involves the creation, maintenance, and architecture of communication networks. It is a combination www.boardroomco.net of electrical engineering and telecommunications.

The most famous computer network is the Internet which allows millions of users to connect and utilize the same resources at the same time. The network uses a packet switching model to channel data traffic through a nearly infinite number of paths and connections. Each packet includes control information and user information. The control information includes the source and destination network address as well as error detection codes and sequencing information. The data part of a packet includes the payload.

In a typical business network there is a central server that stores data and manages user access to essential resources like photocopiers, printers and files. The server is protected by firewalls and a system of multifactor authentication to ensure that only authorized users are able to access the network. Keeping all the information centralized on servers helps administrators to conduct regular data backups and enforce strict security measures for the network. It also lets employees access corporate services and apps, regardless of where they are located like video-calling software as well as document-sharing.
