Computer networks connect devices, computers and other computers to share resources, information and services. They can be based on wireless or wired connections and can be configured in a variety of network topologies. Networks are vital to business today, and help us communicate, collaborate and work more effectively. They also aid with data security and access.
Computer networking is a broad area that encompasses the concept, architecture, creation and maintenance of communication networks. It is a blend of electrical engineering, and telecommunications.
The Internet is the most renowned computer network that allows billions of people to connect and share the same resources at the same time. The network utilizes a packet switching model that routes data traffic through an almost endless number of possible connections and pathways. Each packet contains control information and user information. The control information includes sources and destinations network addresses, error detection codes and sequencing information. The data part of a packet includes the payload.
In a typical network for business, there is a central server that stores data and manages access to crucial resources such as photocopiers, printers and files. The server is secured by firewalls and a system of multifactor authentication to ensure that only authorized users can access the network. Keeping all the information centralized on servers also makes it easier for administrators to conduct regular backups of their data and enforce strict network security policies. In addition, it enables employees to access corporate apps and services regardless of their whereabouts, such as www.boardroomco.net/how-to-normalize-data-in-excel video-calling, document-sharing and other software.
