This is the hardware part.Lets take a look at some of the softwares that we and specifically I, use on a everyday basis.
Everyday, one uses software like Microsoft Office, which helps us to maintain data in a way that helps us to view, store, select, and sort data in our way. Software like Tally helps an accounting firm in a huge manner which stores the data in a accounting language and prints the data in that manner. Tally is one of the most popular software packages. As the name indicates, Tally does not tally or tallying of things and is basically used as accounting softwares also takes care of inventory. Personally, I use a software that helps me to keep a track of all the customers that give us a call. It keeps a track of the customer when did he call and its complete history and also the problem that the customer has currently. It is called as CRM (Customer Relationship Management) software.
Thus, Information Technology has been a boon the world and has many parameters that have their uses in our present lives as well as in future.
