2010; mankind has come a long way since the first discovery of fire a few hundred thousand years ago. Fire used to be a necessity then, now the computer is a necessity for us as we use it in our daily lives.
One way computers help us is in our lives. We use the computer to communicate with people such as web conferencing with friends who are overseas, to look up on information about a particular topic, socialize on social networks such as Facebook or even to do something as simple as sending an email or digital cards to friends and loved ones.
The computer has also managed to change us from reading hard copies of books, magazines and newspapers, to reading online digital documents such as online newspaper articles and e-books.
In education, lecturers are now using PowerPoint to make their lecture slides which are used during their lectures and students are now able to download the lecture slides into their computers and store it as reading documents.
In the working place, paperwork is now slowly converting from manual printing and keeping documents to storing documents in the computer. The problem with paperwork is that it takes up a lot of space and an office has limited space. Moreover, going digital will help the environment as there will be less demand for paper which results in lesser trees being cut down to be made into paper.
However, there have been some issues raised about digital documents. A digital document can be created and edited by anyone, thus this leads to the owner verification problem. It is dangerous in the working environment, because anyone can edit a contract or agreement after it has been signed and used it against the other party. Another problem would be if one accidentally deletes the document, it will be hard to trace the perpetrator and also very hard to retrace the document.
