It’s a mechanism by which varied computers in a terminal is connected to one another with or without a hardware line.
This network allows an individual to access his office or residence computer from anyplace in the world. Sounds great!! Well the advantages do come with its shortfalls. Earlier than we move on, to the various type s of threats that plague the pc network. Allow us to first understand the completely different types of network. UCCP (Unix to Unix copy) – it was one of many oldest form of network that was used to connect computer systems utilizing the UNIX platform. Later on however it was used by PC’s, Mac’s Amiga’s etc. The dynamics of this network was comparatively easy and it used dial up system to connect two computers. This network system has witnessed a journey down south after the advent of the Internet. Right now UCCP network is only used by folks to repeat files.
