What is data network? How data is transmitted? It is a system in information technology which is designed to transfer data from one access point to another or several other points or computers using data switches, cables, hubs, and system controls. The main purpose of a networking or data transmission is to facilitate communication between computers and sharing of information among several terminals, which would include individuals and organizations. There are two primary types of networks and they are broadcast network in which information is transmitted from one node to several nodes at the same time and another is the point-topoint network which allows senders to communicate with one receiver at a time. Data networking cabling is the backbone of networking and they are configured according to the need of an office or organization.
3 primary methodologies are used to transmit signals and they are:
Circuit switching – a dedicated communication channel is established before two nodes communicate in a network Message switching –in this a message is routed in its full form to another switch which stores and read the information before transmitting to the next switch Packet switching – here the communication data or message or information is grouped in to packets before they are sent over a digital network. This done to ensure no data lag is experienced in terms of speed and the message is assembled at the other end reassembled.
Data networks depend on TCP (Transmission Control Protocol), IP (Internet Protocol) and IPS (Internet Protocol Suite) to communicate across machines and the process is dictates how data should be packed, addressed, transferred, routed and received in the end. Computer networking technicians install network cables according to the needs of an office process and its configuration.
IT support also provides repairing services to smartphone & tablets. These are two vital communication devices that enable vast span of users including professionals, students, housewives, businessmen, elderly people and industries and businesses at large. These instruments need to perform at optimum level to be effective and any wear and tear or repair can put halt to operations as communication will be disrupted. There won’t be phone talks, entertainment, music or shopping if these devices become defunct and Smartphone Tablet repairs Gauteng ensures that they are restored and be useful to users with their quick and alert services. it needs proper training and knowledge to repair these communication devices as they are made up of intricate technologies that are patented to each device
