Telephones have been a been an essential part of communication and was the first to device to modernise instant communication, the telephone was created between the mid to late 19th century but was patented by Alexander Graham Bell in 1876, many may argue that he was not the first to create but it is widely accepted that he did have a great deal to do with the telephone becoming prominent within private homes. As telephones became a standard that was accepted by the masses, it would go on to change many thing including how businesses, government and households would operate. Telephones have affected LAN and WANs because it has made it accessible for people to connect to a LAN or a WAN. Telephones have evolved from being used by Alexander and

In most home phone connections even if there are more than one phone in the house it doesn’t mean you could call multiple people at once. Telephones have also been developed to be implemented into networks by connecting them to the internet which gives users the ability to use the telephone on a WAN and have it more accessible this is typically used in business environments were calls need to be cheap and reliable. So using the telephone through the internet is ideal in these circumstances. The most recent advance in telecommunication is mobile phones, since the late 80’s mobile phones steadily gained popularity with the mainstream worked and now has become a standard in everyday and business environments even being supplied by some business because of their reliable and easy use. Mobile phones have changed the way LAN’s and WAN’s operate because of the instant messaging via text, video messaging like skype or facetime, image through instagram and

Within a computer communication is done most commonly with synchronous communication because of a microprocessor clock that runs tasks at scheduled cycles. Which means that the clocks in the devices that are both transmitting data and receiving must be synchronised, this means they must be running at the same time so that the signals are on the same intervals and the data doesn’t have to stop and start the process of sending data. Another way you can think of synchronous communications as is that it is real time. Synchronous is the opposite to asynchronous, asynchronous is the process of data being sent and then it is not received automatically, but it has a start and stop and starts being sent again when the recipient requests the
