Flow Control at Data Link Layer

What is Flow and why we need it to control? In general, controlling the flow of data packets form one end to another is called flow control. We need flow control as much as the other functions like error control etc. But the answer still not proved yet. To understand that lets take an example of data transmission from sender to receiver with NO ERRORS in data. Suppose the speed of sending data packet…

Difference between IPv4 and IPv6

IPv4 is the 4th version of IP and was successfully implemented globally by the IETF (Internet Engineering Task Force) in 1981 to avoid the problem of addresses by assigning each and every device a unique IP address but now the time has been changed and IPv4 doesn’t have enough IP address to be assigned to all the devices. so we need something new and successor…

what is basic difference between Frames, Packets and Segments.

This must be the pickle for many users to differentiate between Frames, Segments and Packets because all of them have almost same functionality i.e. to break the data into parts and add some extra Bits/Bytes and sent it to the receiver. But that is not true, all of them have their own predefined functions and also predefined way of adding extra bits or bytes to the data and send it…

Future trends of Wireless Communication

Future scope: In immediate future, the demand for wireless internet access through mobile phones will be on rise, with greater emphasis on the higher speed and better performance. To lost of a call in wireless internet access also in very high today, because since the present day wireless data services are based on circuit switched radio transmission, where in a complete traffic channel is allocated to a single user during…
