DATA NETWORKING
WHAT IS A DATA NETWORK?
A data network is a system designed to transfer data from one network access point to one other or more network access points via data switching, transmission lines, and system controls. Data networks consist of communication systems such as circuit switches, leased lines, and packet switching networks.
Data networks refer to systems designed to transfer data between two or more access points via the use of system controls, transmission lines and data switching. What makes a data network unique from other types of networks is that it is set up to transmit data only.
HOW DOES IT WORK?
Generally, data networks are defined by their ability to transmit signals via packet switching. The data message is broken down into discrete bits called packets, and these packets are then sent over a digital network that uses an optimal route to minimize lag in data networking speed. Once transmitted, the packets of data are reassembled after they arrive at the destination.
There is a wide range of benefits to using data networks that are worth understanding before you begin to adopt this approach. To start, it's useful to learn about the top three.
1. Communication
Perhaps the largest benefit of using a data network is its ability to enable fast and seamless communication. Linked computers over a data network can communicate with each other and transfer files without the need for physical transfer media.
2. Collaboration
A data network can enable seamless collaboration between two geographically separated individuals or teams. Multiple users (connected over a data network) can simultaneously work on the same project or document remotely.
3. Resource Sharing
A data network doesn't require a physical connection to share information. This means that resources such as the internet, storage medium and printers can be shared between two or more nodes.
