Computer and Internet
Computer, a household word in today’s world, owes its origin to the term ‘compute’ – to add on. Thus, computer is an electronic device which compute huge sum of data very quickly – almost at the drop of an eyelid and for long duration and does so quite easily.
All that a person will have to do is just hit modestly at the keys on the keyboard and the results/data are saved immediately – stored or displayed on the screen.
Computers have increasingly become a part of everyday life and their utility are no longer confined to scientists, engineers and technocrats.
No stream of human life is now a days left untouched by computers. It’s no longer just important but computer is an expected phenomenon for people from all walks of life – business, scientists, medicos, students, housewives and even ganglords and gamblers.
Computer is used to calculate telephone and electricity bills, used to play a variety of games and million of other application.
Though popularized in the last century, especially in the last decade, the origin of computers was attempted long back. Actually, in 1946, John Von Newmann first summarized all the requirements of a computer. One of the first computers based on Newmann’s principle was possible way back in 1948.
In 1955, the magnetic core storage was invented which came to be known as second generation computer. Subsequently, the third and fourth generation of computers also came in. The application of microelectronics in computer devise came to effective from 1974. Now a days, the fifth generation computer is being talked about abundantly. These are being billed as the computers of tomorrow and will be capable of thinking and making decision of their own.
‘Artificial Intelligence’ will be applied to these computers to help them ensure understand voice, languages etc.
The Japanese IT players are already calling their fifth generation computer a ‘knowledge information processing system’ (KIPS). In circa 1981 the first announcement was made about the plans for the fifth generation of computers and the Japanese authorities announced spending an initial budget of $450 million with plans to enlist equal amount if not more financial support from the industry. Here the goal was to develop computers (intelligent computers) that will be able to converse with humans in normal language, speech and relate to the pictures. These computers were aimed at making revolutionary changes in terms of making inroads into the hitherto exclusive province of human mind and reason. Historians and IT commentators also viewed at the Fifth Generation computer as an exquisite devise piece aimed at fostering greater economic strategy for Japan in terms of achieving for itself a greater global role in hardware, software, IT programming languages and organization build up. On April 14, 1982, the Institute for New Generation Computer Technology (ICOT), was formally launched with upgraded laboratories in Tokyo.
Types of Computers:
In our modern times, the computers are classified into four major categories depending basically on the speed, cost and storage capability. They are personal computers – commonly used by individuals for personal purposes. It’s largely used at work places and at home. Mini computers are mostly used in big organizations. Other types are mainframe computers and super computers. Super Computers are costliest of devices known till date and most of these super computers are comprised of several good and high performing computers working in a parallel single system.
Also in our recent times, we have emergence of laptops also called notebooks and palmtop.
The notebooks could be slightly larger than hardcover books and therefore such a name. Mostly useful for being convenient to mobile computer users they can include everything like keyboard, processor, hard drive, memory card etc in a battery-operated system.
The palmtops are commonly known as PDAs, personal digital assistants and depend its function primarily on touch screen and use flash memory instead of a hard drive.
The laptop sales in recent times have been so brisk that they have even outperformed desktop purchases in 2005. In several countries, many IT vendors have opted for launching their own variety of laptops and the existing players only brought in a sea change in improving the devises.
There is already a huge surge of migration from desktop to laptop. Even school students are preparing their budget to pick up a laptop. Hence with our experience anybody who needs to be in the race of technology survival need to buy one. There is no denying that more and more citizens across countries are going mobile; so are their basic IT requirements and therefore the craze for laptops.
The upward turnaround in notebook sales can be largely attributed to increased IT consumption by Industry verticals and corporate sectors such as Telecom, Banking & Financial Services, Manufacturing and IT-enabled services. Moreover, despite certain hiccups, e-Governance and digital divide initiatives of the central and Governments are also driving IT consumptions. It’s a lifestyle statement. There is an increased aspiration to hold a laptop. It’s the new in thing. The notebooks are emerging as everyone’s favourites with weights and prices coming down and features and performance growing.
One of the main criteria for notebook acceptance has been the widespread availability of wireless connectivity.
The falling cost of components and duty reductions are the key factors that have contributed significantly to reduced prices. The gap between a good notebook and desktop is definitely closing.
The notebook is fast becoming an essential take away for chartered accountants, architectures, physicians and countless others with mobile kind of job. For professionals, desktop is soon becoming a thing of past. With laptop prices making a nosedive and weights shrinking, it is to everyone’s liking now.
Internet is meachanism, commonly called network of all networks, that is used to sore and transmit data by using of the Internet Protocol (IP). IP can be used over a network connecting two computers.
The IT industry is now facing the issue of efficiency as some limitations do figure
in IP transmissions – such as data corruption, timing of delivery, duplicate transmission and receipt of messages, lost of original materials sent etc.
The information/messages are carried in terms of electronic mail, file transfer etc and the system is interlinked through World Wide Web (www) as is better known. A few common methods of accessing the internet include dial up with a landline telephone, broadband facility besides Wi-Fi, satellite and 3G technolgy cell phones.
So much has been the utility of internet in modern life that intervet cafes have mushroomed across towns and villages – lane and by-lane.
Authorities have also made it a point to ensure internet access points at airports, railway stations and other public places and the dictionary has found a new word called:
Netizen – for a citizen who are crazy about internet facilities.
