Computers were first designed to help a person calculate numbers; this function can be seen as far back as 2000 B.C. with the use of the abacus. Modern computers are simply very advanced calculators. Almost any mathematical function can be plugged into a computer, and the computer will solve almost instantaneously. The use of a computer as a calculating device takes away the monotonous task of calculating by brute force.
Personal computers have completely revolutionized the way the world, lives, works, and conducts business. Strictly-speaking, computers arrived on the scene way back in 1936 when one Konrad Zuse produced what was then called the Z1 computer. This was a cumbersome machine that could perform simple calculations and also crunch simple data. This was not as sophisticated as what we have today but it served to set the foundation for further research and in 1944, John Atanasoff and Clifford Berry from Iowa University built on this model and produced several innovations of the computer which was capable of producing arithmetic calculations, parallel [processing, memory regeneration, and other simple computing tasks. The research was taken further at Harvard University, then IBM, the business conglomerate joined the fray and in 1953 produced what was then the world’s first sophisticated computer. Even then, it was still large, occupying entire floors and consuming untold power.
As we have mentioned, computers have completely changed the way we live and work. Today, computers are in almost every office. There are still offices in some parts of the world which still don’t have computers but this is now rare because, without computers, work is inefficient and cumbersome. Take for instance calculations. It would take days for companies to do simple calculations not to mention companies that deal with lots of material and inventory. Computers make this work simple and allow businesses to become more efficient on a day to day basis.
Another use of computers is communication. With computers has come the wondrous world of the Internet or what is called in other circles, the World Wide Web or Information Superhighway. As much as the computer has changed the way we work, they have also revolutionized the way we communicate. The term “the world is a smaller place” or phrases like “global market place”. This is because the Internet has made communication so easy and seamless that there have people can communicate instantaneously regardless of what part of the globe they are located. The world of email, although it hasn’t completely resulted in the eradication of snail mail, has nevertheless caused a decline in visits to the post office or the purchase of stamps. All this is because people now sit behind a computer and email back and forth. To go even further, specialized Internet software run by many major companies such as Microsoft, Yahoo, and Google has made it possible to chat in real-time with someone on the other side of the globe. Video conferencing has also been made possible. This has completely changed the way we conduct meetings. Businesses can now even open branches in other countries faster because top-level management can communicate with lower management via video conferencing. People can actually see each other regardless of where they are located and all this is courtesy of the advent of computers and the Internet. Computers have evolved a lot since and are now in almost half of all US households and most offices in the rest of the world.
Personal computers today can hold up to 32 gigabytes of memory. They can be used to store music, pictures, documents, videos, and much more. Computers are able to be reprogrammed to suit any user’s needs. This is one of the key traits of a computer today.
Computers have changed the world in many ways. They allow huge amounts of information to be stored in a small space. They also allow a person to calculate mathematical problems with ease. Finally, computers allow people to communicate with one another through internet sites such as Facebook, Whatsapp, and Twitter.
In today`s life computers have impacted many fields such as the business fields. Many business organizations need computers to keep track of accounts, money, and other stuff that they need. It has been noticed that business people use computers a lot both in their homes and in their working places. One may see that these people make pie charts and graphs that they use for presentations during business meetings where most of these charts were made with the help of computers. The business field uses computers a lot in their activities.
Nevertheless, the business organization nowadays use online marketing to advertise and contact with their consumers from different parts of the world without direct contact. For instance, at Amazon, this is an efficient way of business since it does not limit the area of supplies and consumers. It is through the use of computers that they are able to perform these activities.
Another area that computers have impacted is the entertainment area. It has been seen that most of the people love science fiction and action movies and those that have neat effects like Matrix or Harry Potter. Well, the graphics and animations used in those movies were done by computers themselves. Most of the movies today use these graphics to make movie effects look realistic. For instance, in Harry Potter where Harry has to fight dragons and big snakes, all those effects look real but they are not realistic and some movies where we see aliens, space ships, monsters, or flying men. Some movies are even made by computers from top to bottom like Toy Story and Wall E.
Not only movies but also game consoles use computer animations like the Play Station, PC, and Nintendo. And it has been seen that games made by 3D graphics have been a big breakthrough in gaming. All thanks to the awesome computer graphics. Even the music industry has been impacted in its way. Since music editing and video making all require computers to create effects or edit videos. Thus computers have a great deal of effect in the entertainment industry today.
The educational field has been impacted by computers as well in its own way. Like in universities computers help students a lot with their assignments and presentations. For instance, a student had to do a project on World Religions; he would use the encyclopedia to search for information. Even when presenting their works like for presentations one would use Microsoft PowerPoint and writing of essays would require Microsoft word.
Even teachers themselves use computers as well. They use computers to keep track of grades or prepare notes and presentations for their students. Through servers/networks educational institutes can share and control resources, by connecting computer devices together which saves a lot of time and money. For lecturers it becomes easy when a lecturer is giving a lecture then students can just take note rather than printing out pages and pages of notes. Nevertheless, e-learning is also a product of computer development. Thus computers have a great deal of importance in the educational field.
This is one important field that computers have impacted. Computers help in hospitals and even in small pharmacies. Doctors and nurses use computers to make records on medication of patients and in what amount so they wouldn`t lose track. But in big hospitals computers are also used to keep records of every patient. They also keep records of medical bills and equipment.
Nevertheless, scientists need computers so they could find cures to different diseases that keep erupting every day. If it wasn`t for computers these cures wouldn`t have been found. Therefore computers are important since they help us maintain our health.
Computers have had a great deal of impact in this area. Computers help in designing the right kinds of equipment and ships that are used nowadays for most exploration. For instance, a large organization like NASA needs these kinds of machines for space exploration. In space, small errors or miscalculations can create serious problems that cannot be easily corrected. Computers provide faster and more accurate handling of data, both in planning a mission and in analyzing parameters during a mission. Without them, effective space exploration would be nearly impossible. This has proven to be successful since the everyday huge deal of inventions and discoveries from these explorations, like life in mars. And now scientists are trying to find if there is another life form on other planets. Computers also help them to solve complex mathematics such as from which degree/angle should the rocket be launched, which would be quite difficult for humans to calculate.
Finally, computers have changed the way that we communicate as a society. People can now talk to one another in almost no time at all through the use of social networking sites, and people can even live video chat with applications such as Skype. Imagine, if this idea had been presented to scientists 50 years ago, the presenter would have been laughed out of the conversation.
