Good Uses of Old Computers
Personal Entertainment System
This is probably considered to be the most common choice of users planning to purchase a new computer. If the PC is in running condition and has a decent hard drive space, you can use it as a personalized entertainment console. You can install software for playing audio files, a DVD drive, a powerful speaker system, and other devices in a typical entertainment system. You can even arrange web access on this system, in case you want to play online radio or watch movies.
The first computers developed were mere calculators, with the ability to carry out simple arithmetic operations. Advancement in electronics, the development of the vacuum tube based transistors and devising of digital logic gates led to development of the first digital computer which could perform more advanced logical operations.
These early machines took up whole multistorey buildings and were operated through punch cards. All this changed after the development of semiconductor based transistors which led to the extreme miniaturization of integrated circuits, that made the development of the first personal computers possible.
How Computers Changed The World Over The Years
Computers have changed the way a business functions in a large way. Back in the olden times, corporate houses rented spaces for running accounting departments. It took months together to figure out profit or loss that a business had made or suffered. Recording entries and other relevant data was done manually and most of it remained scripted. However, with the advent of computers, the concept of manual entries and use of human brain to remember and memorize company’s financial operations became obsolete. This transformation was known as automation, which made computers the backbone of all new age businesses. Today, computers are used beyond bookkeeping purposes too. Almost everything that happens in an organization, right from its inception to its closure, is recorded, worked upon, evaluated and rectified with the help of computers.
Role of Computers in the Health Sector
Availability of Information
Internet provides information on everything. New discoveries regarding operative procedures, medicines, study reports, are available on the Internet. You can easily order medicines from any part of the world. You can send medical reports via e-mail and get suggestions immediately from a doctor who is far away from you. Direct, live telecast of operation from a remote corner of the world can be watched in any part of the world. Web conferences help doctors to learn techniques without wasting time in traveling. Lives of critically ill patients can be saved, as time is saved.
Applications of Computing Technologies in Agriculture
In today’s times, agriculture is not just about crop production or livestock farming and associated activities. The challenges brought forth by ecological factors affecting the environment need to be a major consideration for any kind of farming activity. Farmers need to preempt environmental impact due to climate change and this is where modern technology comes to the rescue. In a nutshell, the uses of computers in agriculture include:
