Impact of IT on communities

IT has effected almost every community over the world.

It is slowly making huge changes to the education communities of the world. Now people can get whatever information they desire through a simple online search, information that otherwise may have been lost in one country and discovered years ago in another, all online.
It has also made the lives of secretaries etc (arguably) a lot easier. No more giant filing cabinets filled with thousands of fragile sheets of paper.

Since the technological boon of the sixties, military technology has increased immensely as well. Helicopters and planes are controlled as much by computers as they are by the pilots themselves. New weapons and technologies are developed all the time. Through the use of computers, soldiers can be dropped and picked up wherever in the world is required.

Blogging

Blogs are a very largely used specialist communication channel. It is a very effective means of displaying information over a whole page without having to create an entire website and all the hassle that comes with. It allows you display information in any format and make it available for replication.

It can be updated in a much more manageable manner than website can with small updates called posts. Often people make several posts a day.

They can serve a wide variety of uses. It could be a personal blog you make for yourself, making diary-style posts that you don't mind other people reading and commenting on. Or you could use it to broadcast information/news to a wide audience of followers.
Some people update their blogs with music, mp3 blogs, photographs, photoblogs, or video, videoblogs.

Facebook

Facebook has reshaped social sciences around the world. Before such platforms as facebook and myspace, you had to get to know people.. by actually getting to know them.
Now if you ever meet someone interesting all you have to do is type their name in a box and a whole web-page pops up with their information, pictures, and list of contacts. There are privacy settings but as a whole they mean very little. 
You will never know who's browsed your page or what opinion they've taken of you from it. I find this disconcerting and personally have 'deleted' my profile for this reason. I found out when deleting my account that Facebook aren't so eager to let you go. 
In fact, you can't actually immediately delete your account. Upon selecting account termination you are given two weeks grace to 'change your mind'. This will often lead to automatically signing back into your account by accident and completely resetting the two-week deletion period. 

Even after the account deletion. Facebook has the right (you accepted when you signed up), to  "store data for as long as it is necessary to provide products and services to you and others". 

This basically means that Facebook have the legal right to hold any information you have given for as long as they deem "necessary". This allows them to hold the information for as long as they want until they're legally obliged to delete it after 5/6 years. 
This, considering the number of facebook users in the world, is a very dark omen for humanity.

Threats of IT

The internet has undoubtedly made our lives easier and increased humanities efficiency as a whole. However if some alien creature were to take their perspective of humans from the internet we would almost certainly be deemed lower beings.
The internet allows people to show whatever side they wish, and hide everything else. It is a lot easier to deceive people you aren't speaking to face to face, this leads to a lot of scamming and deception.

People even go so far as to make fake 'people'. It's a simple task to take a picture from the internet and claim it as your own. Most people will take this at face value unless it is especially unbelievable. This may not seem like such a big issue, but it has the potential to ruin lives. People can fall in love online but this is probably 90% of the time not as it seems. The word "catfish" has had a new definition added to the US dictionary.

USinformal

lure (someone) into a relationship by adopting a fictional online persona.

"he was being catfished by a cruel prankster"

 "Catfishing" is the act of luring people into fake relationships for personal gain, or due to other parameters. People do this for money, information, items, or more sinister reasons.

Use of computers in our day to day lives also means a lot of information about us is stored online. This information is valuable to both hackers and big corporations. Information about people sells, and both sides of the law will try and use it to their own profit any way they can.

To stay safer, you should make sure you use a constantly updated anti-virus and have a good firewall as well.

Impact of IT on others.

Computers being a large part of day to day life comes with drawbacks however. The most obvious being that, you need access to a computer. Not only that, some people, especially people who've had little reason to keep in the loop of computers previously, now have to learn how to work a whole new type of interface.
Learning how to use computers as a high school or college student is a lot easier than it is for someone who was born and grew up in a world different from the one we now live in.

Social Impact of IT

Today's society has become almost completely dependent on IT use in our day to day lives. This has completely reshaped the environment we as humans grow up in almost everywhere in the world. Society has always shifted like this however. New generations adapt to new technologies that spring up, the old complain and the young wonder why. 

However, never before has technology progressed at the speed it is doing so right now. 

In 1965 Gordon Moore, co-founder of Intel said, 

"The complexity for minimum component costs has increased at a rate of roughly a factor of two per year. "

From the graph above you can see how correct he was. From 1971 to 2011 the transistor count in microprocessor, CPU, chips has roughly doubled every two years. 

This has never been as exciting and alarming as it has right now. Old computers have only really been able to perform rudimentary tasks, but as they have evolved and become smaller and smaller, they've slowly crept into our lives whether we were aware or not.

This has many implications humans have never really needed to consider before.
