Network Communication protocols

These technologies to work need internet protocols to allow them to send data through out the internet . These technologies are :

  • Peer to Peer : this protocol makes the clients that want the data into “servers” . This splits up the data to different computers and you give and take data as you are connected . Unlike other protocols which degrade with more users peer to peer increases performance as more users join in, but suffers from “leechers” that only download the files but never upload back causing a degradation in performance.

  • TCP/IP : is a protocol that consists of a Client and a Server . This means that most of the time your download speed is only limited by your Isp and the amount of people connected to the server . It is the most stable of protocols but degrades in performance as more and more users connect to it .

  • UDP : User Datagram Protocol is a protocol which is much faster than TCP/IP and has less latency than other protocols it is used for things likes VOIP and online games that need a fast connection. Although UDP is fast is easily prone to interference and will continue sending packets even if a packet is lost .

Technologies and communication protocols.

There are many different types of internet technologies and protocols used today each has its advantages and disadvantages:

  • Asynchronous transfer mode (ATM) is a switching technique used by telecommunication networks that uses asynchronous  time-division multiplexing to encode information into little, altered measured cells..This is different from Ethernet , which use variable packet sizes for data or frames.

  • Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network (PSTN) to create connection between the ISP and the Computer by calling a telephone number. The user’s computer or router uses an attached modem to encode and decode information into and from audio frequency signals, respectively. Dial up can reach speeds up to 56 kbps.

  • Digital subscriber line is a family of technologies that are used to transmit digital data over telephone lines. These technologies can work simultaneously  through the same line there for one call take and receive call and also be connected to the internet.
