Computer networks connect devices, computers and other computers to share resources, information and services. They can be wired or wireless and set up in various network topologies. Networks are vital to business today, and help us communicate effectively, collaborate and collaborate efficiently. They also help with data security and accessibility.

Computer networking is a vast area that encompasses the development of, maintenance, and design of communication networks. It is a blend of computer science, electrical engineering, and telecommunications.

The Internet is the most well-known computer network that allows billions of www.boardroomco.net/why-is-firefox-so-slow-and-how-to-deal-with-it people to connect and share resources at the same time. The network employs a packet switching model to direct data traffic through an almost limitless number of connections and routes. Each packet contains control information as well user data. The control information comprises sources and destinations network addresses errors detection codes, as well as sequencing information. The payload is contained in the data portion of a byte.

In a typical network central servers store data and manages access by users to essential resources like printers photocopiers, and other files. The server is protected by firewalls and a multifactor authentication to ensure that only authorized users are able to access the network. The centralization of data on servers allows administrators and security policy enforcers to carry out regular backups. It also allows employees to access corporate services and apps, regardless of where they reside — such as video-calling software and document-sharing.
