Computers In Our Society

Computers are perhaps the best invention by man so far. To understand the full impact of computers on society, we will first have to understand the meaning of 'computer'. A Computer does not necessarily mean a monitor, keyboard, mouse and a CPU.
A computer is any machine or device that can compute and execute instructions given to it in the form of programs. So technically, even a cell phone is a computer. And so are desktops, laptops, tablet PCs and PDAs. Anything that can perform a series of operations on its own is a computer. One of the most important advantages of computers is in the field of science for research and development. The computers have played a major role in most of what we know about ourselves and the universe. The satellites, the telescopes and almost all the research tools make use of computers in some or the other way. The high-end machines used for diagnosis and cure of many diseases are nothing but computers. There is a huge source of information. There are online universities that deliver online degrees and distance learning is spreading far and wide. Many schools and colleges have started making use of audio-visual ways of imparting knowledge. The banking sector has improved on fronts such as security, ease of use, etc. with the help of computers. Most of the banking operations can be done online, known as Internet banking, and you don't have to walk up to the bank for virtually anything. You can withdraw money from ATMs and deposit money in any branch, thanks to the networking affected by the use of computers. High-end computer devices have ensured that justice is more effective. CCTV cameras and other computer operated security systems have reduced the amount of crime. And if it still happens there are many ways to track down the criminal in no time. The field of entertainment has been revolutionized by computers. Animation, graphic image manipulation etc has made the entertainment experience hundred times better. Computer gaming is achieving new landmarks in terms of technology. Movie making, editing, music composition etc everything needs computers. Computers are helpful because they offer a wide range of functions and services that are not available anywhere else. There are four main uses: word processing, internet/communications, digital video/audio composition, and desktop publishing. The word processing capabilities of computers are amazing. They can automatically correct your spelling and grammar mistakes. The cutting and pasting features are incredibly simple and very useful for revision. Plus it is easier to read a word-processed document than one written by hand. Having a digital backup is an added benefit. Computers supply an affordable solution to nonprofessional audio and video composition. These reasons are why computers are so helpful in modern society. With the aid of computers, humankind is entering a new era of enlightenment.
