Data: It’s everything. It’s photos and films, it’s music, it’s gaming, it’s business, it’s communications, it’s all we touch, everything we do, everywhere we go. The lifeblood of modern business, modern leisure, modern living. But unless your data is accessible, it is reliable and is fast… you’re missing out. With life revolving around data transfer we all rely on rock-solid network installations to keep the data flowing like it needs to. The days of having to thread your home, office, or workplace with miles of data cabling just to be able to plug your computer into the internet are well and truly over. The world’s gone wifi. Pick up a laptop or tablet and take a stroll. Sit in the garden and surf. Play, post, Facetime, follow, and friend from pretty much anywhere. Anywhere with available, reliable, and fast data access. Which of course in this day and age is everywhere.
Data Network System Design
The data network is the core infrastructure that so many systems depend on in a modern building, campus, or entire corporation. Because more and more systems and applications are depending on the data network, the progression of networking is happening at a rapid pace.
Computer Network
A computer network is a digital telecommunications network for sharing resources between nodes, which are computing devices that use a common telecommunications technology. Data transmission between nodes is supported over data links consisting of physical cable media, such as twisted pair or fiber-optic cables, or by wireless methods, such as Wi-Fi, microwave transmission, or free-space optical communication.
Network nodes are network computer devices that originate, route and terminate data communication.[1] They are generally identified by network addresses and can include hosts such as personal computers, phones, and servers, as well as networking hardware such as routers and switches. Two such devices can be said to be networked when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. In most cases, application-specific communications protocols are layered (i.e. carried as payload) over other more general communications protocols.
Computer networks support many applications and services, such as access to the World Wide Web, digital video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications. Computer networks may be classified by many criteria, for example, the transmission medium used to carry their signals, bandwidth, communications protocols to organize network traffic, the network's size, topology, traffic control mechanism, and organizational intent. The best-known computer network is the Internet.
