Computer networks link computers and other devices together to share resources, information and services. They can be wired or wireless and configured to work in a variety of network topologies. Nowadays, networks are crucial to the business. They allow us to communicate more effectively, collaborate with colleagues and perform more efficiently. They also aid in data security and accessibility.

Computer networking is a broad field that covers the ideation, architecture, creation and maintenance of communication networks. It is a mix of electrical engineering.

The Internet is the most well-known computer network with billions of users to connect and share the same resources simultaneously. The network employs a packet-switching model to direct www.boardroomco.net data traffic through a nearly infinite number of paths and connections. Each packet is comprised of control information as well as data from the user. Control information includes address of the network that is used to connect to the source and destination errors detection codes, as well as 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 access to essential resources like printers, files and photocopiers. The server is secured by firewalls and a system of multifactor authentication to ensure that only authorized users are able to access the network. Centralizing all data on servers helps administrators to manage regular data backups and enforce strict network security policies. It also lets employees access corporate services and applications regardless of where they are located including video-calling software and document-sharing.
