Communications

Communication has evolved  substantially since the invention of the world wide web. Before we used very physical types such a mail, and it has been improved upon many times such as with the invention of the telegram which allowed messages to be send through a physical wire in a binary fashion of long and short beeps. eventually this evolution led to the creation of our modern communication we see today, this mainly being in the form of email, text message and phone calls.

The mobile phone was first made available in japan in 1979 and later introduced to the rest of the world after 1981. it was revolutionary with it being the first portable wireless communication option. before then only land line phones were used, this worked using a huge network of wires spanning the entire country, a residence would have a wire coming from their house which would connect to an exchange point to then go through a different wire to the desired place. the modern mobile however uses radio masts to relay a signal from someone's phone to another's. This can also be done using satellites to be able to call and text internationally but both methods of phone calls let people connect instantly from anywhere in the world.
A huge 6 billion people have access to a mobile phone and this number has been made in recent years by newly developed country like some in south east Asia. the use however can sometimes be blocked by a bad signal, for example in the UK the extreme hilly environment means for more troubled connections, this backed up with the fact that i don't get phone signal from my own bedroom and have to go to the other side of the house to gain it. however in somewhere like Florida in the USA the terrain is very flat to allow the need for less but taller radio towers so much so that you can at least one from anywhere in the state.

With the introduction of the world wide web across the 1990's the invention of electronic mail meant people could quickly and formally send each other messages of the internet to anywhere in the world . this done using satellites, the email is converted into a signal which is then sent down a physical wire to a transmitter which then sends it to a satellite and back down to a receiver in a different country such as India and then to another receiver of another person. this coupled with the mountain of spam emails some people receive may encourage people to not use email and as of 2014 there are 2.5 billion active users of email which means more people up to no good while more people become active members of the online community.
I use email on a daily basis with school and leisure. i use it to send work to my teachers and i use it at home to have updates and posts sent to me all in one place which is one of the many advantages of email in that you can link all of your accounts to one specific feed.
Emails can be sent and received 24 hours a day 365 days a year from any computer that has an internet connection, and can be sent to more than one person. however emails can also hold viruses for your computer if the sender is unknown, other crime such as phishing allows people to view your bank details and other personal information.

But while phone,text and email let us stay connected, it also arises certain problem. such as with being able to communicate with anyone anywhere people begin to feel growing lack of need to go out and physically socialize with friends and family. This in turn making people less social and may lead to health problems due to a possible lack of sunlight if the person is in an office most days. However modern communication helps people around the world connect instantly using many platforms. Phone and text allow users to talk and socialize remotely to friends and family while email lets people send informative and formal text at the click of a button to anyone.
