Packet switching is a network transmission method that sees data sent in small blocks called packets rather than as a continuous stream. Sending data in this way helps to improve the robustness and ...

Packet-switching networks -- networks which break data up into chunks called packets before transport -- help make your business communications stable and efficient. Once used only for data ...

Description: Survey of underlying principles, fundamental problems, and their solutions in designing computer networks. Laboratory projects include using network systems and network simulation ...

An old method of transmitting information (voice or data) through a system or network by establishing a persistent, dedicated connection ("circuit"). This connection consumes resources even when no ...

The fundamental technology underpinning the internet is called packet-switching. And Donald Davies was the first one to call it that. In the mid-1960s, Davies was a researcher with Britain's National ...

When it comes to wireless broadband standards, there are many acronyms to keep track of. However, few are more important than LTE and 4G. Knowing the difference between 4G and LTE (and now 5G) might ...

If you thought that the digital TV transition, with its billion-dollar coupon program for converter boxes, was a migration nightmare, wait until it's time for the phone system to dump its legacy ...
