The vast growth of IT has resulted in changes to the way people live and function from day to day. One of the areas that IT has greatly affected are businesses. Before the IT revolution, most of the jobs like calculating spreadsheets were done by hand and therefore businesses had to spend a lot more of their wages on trained staff that could do this efficiently. This meant that there were certain jobs people trained for and have worked at for years however with the introduction of computers, those jobs started to disappear. This is because specialised staff was no longer needed, everything could've been done on a computer, operated by one person. It was a lot cheaper and the amount of errors was also smaller because all the calculations were done automatically; all you have to do is type in the numbers and the computer will do the rest for you.
Word & Excel

Word is used for documents like letters. Before Word was invented, businesses had to employ typewriters who needed training and had to be payed. Because everything was written on a typewriter, it meant you couldn't make any alterations and therefore if any mistakes were made, the document had to be written all over again and this was time consuming. It also didn't give you much of a choice, you could only write in one font which meant that every document looked the same and kind of boring to read. Using Word allows you to; choose from thousands of fonts, edit your work at any stage, delete single letters, and even paste pictures like the company logo or a graph. When you're done you can print it all of in a matter of seconds.
Excel on the other hand is mostly used for spreadsheets like balance sheets, profit and loss accounts or any other document that involves calculations. It can also be used to make timetables, statistics, comparisons, etc. For businesses it's one of the most useful software because again, it only needs one person to operate where as years ago it would've had to be replaced with a whole team of employees who would have to make calculations themselves with a possibility of making mistakes. They also had to be paid a lot meaning that business expenses were going up.
Jobs
As I've already mentioned, a lot of jobs disappeared however a lot also opened up meaning that the job opportunities increased. These are some of the office jobs that opened up with the introduction of IT:
- Web Designer
- Network Administrator
- IT technicians
- Computer Sales
- Technical Support (Call Centres)
