Computer networks connect devices and computers to share information, resources and services. They can be wired or wireless and configured in various network topologies. Networks are vital to business in the present and allow us to communicate with colleagues, collaborate and work more effectively. They also aid in access to data and security.
Computer networking is a broad field that includes the creation, maintenance, and architecture of communication networks. It is an amalgamation of computer science, electrical engineering and telecommunications.
The Internet is the most well-known computer network with billions of users to connect and share resources simultaneously. The network utilizes a packet switching model to direct data traffic over an almost unlimited number of possible connections and pathways. Each packet contains both control information and data from the user. The control information includes the destination and source network address and error detection codes and sequencing information. The payload is contained in the data portion of a byte.
In a typical business network there is a central server that stores data and manages user access to vital resources www.boardroomco.net/how-to-type-on-a-pdf such as photocopiers, printers, and files. The server is secured by firewalls and a system of multifactor authentication to ensure that only authorized users have access to access the network. All the data is centralized on servers also helps administrators to perform regular backups of their data, and to implement strict security policies for networks. It also allows employees to access corporate services and apps, regardless of their location for example, video-calling software as well as document-sharing.
