Networks are essential for business today and enable us to communicate with each other, collaborate and work efficiently. They also help with data security and access.
Computer networking is a broad field that includes the conception as well as the architecture, creation, and maintenance of communication networks. It is an amalgamation of electrical engineering and telecommunications.
The most famous computer network is the Internet which allows millions of users to connect and access the same resources simultaneously. The network employs a switching model to guide data traffic through an almost endless number of connections and routes. Each packet contains control information and user information. The control information comprises sources and destinations network addresses as well as error detection codes and sequencing information. The payload is contained in the data part of a byte.
In a typical network a central server stores data and manages access by users to crucial resources like printers photocopiers, as well as files. The server is secured by firewalls and multifactor authentication systems to ensure that only authorized users can access it. The fact that all information is centralized on servers also helps administrators to manage regular backups of their data and enforce strict security guidelines for the network. It also lets employees access corporate services and applications regardless of where they reside including video-calling software and document-sharing.
