Computer Technology & Computer Use value in our life - Read and learn about Computer Uses

What's a Computer
A computer  is a programmable  machine  designed  to sequentially  and automatically carry  out a sequence of  arithmetic or logical operations. The  particular sequence of operations  can be changed readily,allowing the  computer to solve more than one kind of problem. An important class of computer operations on some computing platforms is the accepting  of input from  human operators and  the output  of results  formatted  for human  consumption. The  interface between  the computer and  the human operator is known as the user interface.

Conventionally a computer consists of  some form of memory for data storage,at least one element that carries out arithmetic and logic operations,and a sequencing and control element that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from an external source, and allow the results of operations to be sent out

History of Computer

 The first use of the word "computer" was  recorded in 1613, referring to a  person  who carried  out  calculations , or  computations, and the word  continued with  the same  meaning  until  the  middle of the 20th century. From the end of the 19th century onwards, the word began to take on its more familiar meaning, describing a machine that carries out computations.

How has Computer Technology affected our Lives

Using a computer to write  about computers  is like searching for ‘Google on Google!  Computer  technology is so much a part of our lives, that we cannot imagine a  life without it. Computers serve as efficient data  storage  systems and  excellent  information processors. They can  store, organize and  manage huge amounts of  data. Moreover, they  operate on  incomparable speeds,  thus saving human time and effort to a large extent. True, they are an integral part of our lives. It is said that  inventions  change the way we live. Computer technology is a classic example of this adage. It has indeed changed our way of living.

Uses of Computers in 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. This gives us  an idea as to  how wide and  deep is  the role of  computers  in our lives.We need a computer for virtually everything. In the subsequent paragraphs we will see the uses of computers in society in more detail.

Uses of Computers in Education

Computer uses in the field of education are infinite. The Internet 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. A horde of tools that need a computer, help students in many ways. For instance, a MS word, Excel, powerpoint etc. And this use of computers in education is only increasing.

Uses of Computers in Medical 

The important use of computers in the medical field is for research and development. The high-end machines used for diagnosis and cure of many diseases are nothing but computers. For example, the Magnetic Resonance Imaging (MRI), CT scan, ultrasound devices, etc are amongst the uses of computers in hospitals. Even many surgical procedures, known as laparoscopic surgeries, need the help of computers. Web conferencing helps doctors treat people remotely.

Uses of Computers in Science

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 huge calculations required for space science, safe communication between scientists, storage of all the gathered information are some of the computer uses in science and technology.

Uses of Computers in Banking

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 effected by the use of computers. The complete banking experience has also become more safe. Also read about the use of computers in business.

Uses of Computers in Crime Investigation

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. Forensic science employs computers for many of its operations related to investigations.

Uses of Computers in Entertainment

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.

Uses of Computers in Business

The Information Technology (IT) revolution that brought in the computers has gone through a variety of different stages. The prominent introduction being in 1960s when big companies had to store large amounts of data. As the volume of data that was being churned out began to increase, computer and IT companies such as Apple computers, Microsoft, HP and IBM began to spring up. Moving on to the use of computers in business entities...

The revolution of computers initially was used for complex data bases only. However people realized the many uses of computers and the hardware and software, for computers began to become, more user-friendly and aimed at providing comfort, ease of operation and efficiency to the user. Two major breakthroughs in the revolution of computers were the introduction of Windows and years later the introduction of laptop computers. Another revolutionary introduction was the Macbook, a highly advanced next generation device, which of course greatly facilitated businesses and working people in several ways. Apart from that, hardware such as scanners, CD and floppy drives and printers have facilitated the operations of offices.

Computer-mediated communication (CMC) is defined as any communicative transaction that occurs through the use of two or more networked computers. While the term has traditionally referred to those communications that occur via computer-mediated formats (e.g., instant messages, e-mails, chat rooms), it has also been applied to other forms of text-based interaction such as text messaging. Research on CMC focuses largely on the social effects of different computer-supported communication technologies. Many recent studies involve Internet-based social networking supported by social software.
