"The advent of computers has defined a new age in technology and revolution." As rightly said, things have changed from the past and will certainly change in future. One of the biggest credits goes to computers. This simple looking box has unlimited capabilities which are yet to be unfolded and used for. From entertainment to work, computer covers every prospect of human life.

Today an average child would want a computer at any cost. From a child to an old man, each has his/her own need to have a computer. Since the advent of these machines, innovation and remodelling have led to the reduction in its size from the occupation of a large hall by a single machine to a machine that stands on a small table or fits in a bag and during all these changes, the processing and speed have never failed to improve. With computers around life has been easier than ever. For an example, numerous calculations can be done in a click; we can socialise with people all over the world, share the latest news, and develop projects ranging from art to complex engineering. From monitoring, diagnosing to operations, health uses the help of the computers. We depend on computers for passing idle time. A person born in this age might not be able to survive without a computer.

But even with these advantages and benefits, computers also bring some disadvantages. As all works have started to be saved in soft copy in computers, securing those data has become more difficult. Leakage of confidential information is always at stake. Even through a normal man's eyes, at home misuse of computers and information it holds can cause just but waste of time. Time numerous social sites and applications deviate a human from his daily tasks into the virtual world. Games pull young children into pressing buttons of their controllers and spending hours a day at home instead of enjoying physical games outside.

Therefore, it has its pros and cons; all that counts is how we use it.
