The most common one that is usually referred to as “ethernet cable” today is CAT cabling. The generic blue cable that end users recognise as their internet service - this has become one of the most developed cable types in IT history. From CAT3 to CAT7, many improvements have been made to improve the quality of the cabling, such as giving it a thicker coating to prevent any EMI, or improving the speeds to move data around faster. This is typically the cable that you would visibly see around the office, as it is widely implemented due to a wide range of compatibility and other features such as POE which gives companies a reason to ditch the analog phones and make everything digital for cheaper service rates. But, it’s also possible that you will see the biggest up and comer in a LAN environment, fiber optic.

Synchronous communication was not always possible however, we first started with asynchronous communications (which were still a very important stage for networking). Forms of asynchronous communications would be e-mails, faxes, and even instant messaging can be asynchronous at times when the messages aren’t read instantly. The introduction to synchronous communication meant an increase in networking communications, as the speed would determine how time-sensitive the information
