COMPUTER TECHNOLOGY

Computer technology that is in daily use today finds its roots in the oldest computing systems like Abacus and slide rules. The evolution of computers can be traced back to calculators and punched cards, which were some of the earliest computing devices. Analog computing devices evolved into digital information processors and from then on, there was no looking back! For a closer look at the major events in the computer history, you must go through the full timeline of computers.

For many years after 1960, when the third generation computers were created, desktops remained to be popular for personal and business use. Research in computer technology continued, giving rise to the development of laptops, palmtops, miniature tablet PCs and PDAs. As we see today, they serve as ‘personal digital assistants’ in the literal sense of the term! Their small size endows them with portability, thus adding to user convenience. As they can be operated on batteries, they provide computer users with mobile computing capabilities. How has this affected our lives? Well, we can remain connected to the world at all times. Work is no more location-dependent!

Computer operating systems are a vital component of the computer technology. They help in the management of a variety of computer operations and in the sharing of computer resources. They handle the scheduling and execution of computer programs, help in the management of files and handle interrupts. They manage multiple user profiles and user accounts, thus playing a major role in maintaining computer security. Certain types of operating systems offer distributed processing capabilities and support multitasking and multi-user operations. The most important role of an operating system is to provide the users with an interactive interface. They have made the interaction with computers, a user-friendly experience and made it easy for the common man to make friends with the computer technology.

Computers, as we all know, can perform complex mathematical operations and process large amounts of information. Thanks to their computational powers, long and complex calculations can be performed within seconds. They can be programmed to execute complex instruction sequences through the use of programming languages. That reminds me of the software industry, one of the most progressive industries of the world. Computer technology gave rise to this industry and changed the face of the world.

The multimedia capabilities possessed by the computers make them one of the ideal audio-visual media. They can be made to play movies and music. They offer support to a variety of storage media like CDs, DVDs, floppy disks and USB drives. Computer hard disks are also capable of storing and playing audio and video. And how has this affected our lives? Well, it is due to these storage and audio-visual media, that we can maintain soft-copies of data. Gone are the days, when we used to document on paper! Gone are the days when students maintained traditional notebooks. Many of them possess notebook computers today. Today’s education is about PowerPoint presentations and e-homework assignments. TVs and radios were once, the only means of entertainment, but not any more. Today’s entertainment is about the computer and Internet technology!
