Networks are crucial for business today, and help us communicate effectively, collaborate and collaborate efficiently. They also assist with access to data and security.
Computer networking is a broad field that involves the creation as well as the maintenance and construction of communication networks. It is a mix of computer science and electrical engineering.
The most well-known computer network is the Internet which allows millions of people to connect and use the same resources at the same time. The network uses a packet switching model to guide data traffic through an almost endless number of possible connections and routes. Each packet is comprised of information about control and information from the user. The control information contains the source and destination network address and error detection codes and sequencing information. The payload is the data part of a byte.
In a typical network for business, there is a central server which stores data and manages access to critical resources like printers, files and photocopiers. The server is protected by firewalls and a system of multifactor authentication to ensure that only authorized users are able to access the network. Centralizing data on servers allows administrators and security policy enforcers to conduct regular backups. Employees can also access corporate services and apps regardless of where they are for example, video-calling software or document-sharing.
