The Importance of Computer Networks in Business
Computer networks connect computers and other devices together to share resources, information, and services. They can be wireless or wired and set up in various network topologies. Today, networks are vital to the business. They enable us to communicate more efficiently, collaborate with other people and work more efficiently. They also help with access to data and security.
Computer networking is a broad field that includes the creation of, maintenance, and design of communication networks. It is a combination of electrical and computer science. engineering.
The Internet is the most famous computer network, allowing billions of users to connect and share the same resources at the same time. The network employs a packet-switching model to channel data traffic through an endless number of possible routes and connections. Each packet contains control information and user data. Control information includes sources and destinations network addresses errors detection codes, as well as sequencing information. The data part of a packet includes the payload.
In a typical network a central server stores information and controls access for users to critical resources like printers photocopiers, as well as files. The server is secured by firewalls and a system of multifactor authentication to ensure that only authorized users are able to access the network. The centralization of information on servers makes it easier for administrators and security policy enforcers to conduct regular backups. Additionally, it allows employees to access corporate applications and services regardless of their location — for example video-calling software and document-sharing software.
