The Importance of Computer Networks in Business
Computer networks connect computers and other devices to share information, resources and services. They can be built on wired or wireless connections and can be set up in many different network topologies. Today, networks are vital for business. They enable us to communicate more efficiently, collaborate with other people and perform more efficiently. They also assist with data security and accessibility.
Computer networking is an extensive area that encompasses the development as well as the maintenance and construction of communication networks. It is a mix of electrical engineering.
The most well-known computer network is the Internet that allows billions of people to connect and access the same resources simultaneously. The network uses a packet-switching model to channel data traffic through a nearly infinite number of pathways and connections. Each packet contains control information and user data. The control information includes the source and destination network address, error detection codes, and sequencing information. The payload is the data part of a byte.
In a typical network central servers store data and manages access by users to critical resources like printers photocopiers, and files. The server is secured by firewalls and multifactor authentication systems to ensure that only authorized users can access it. Centralizing all data on servers also helps administrators to perform regular backups of data and to implement strict security policies for networks. It also allows employees to access corporate services and applications regardless of where they reside including video-calling software as well as document-sharing.
