One of the most important things to human beings, especially to those who run organizations, companies, institutions, and etc, is, as we all know, to learn to know how to operate a computer that is commonly used items in many areas today, in that almost anything you know is run or made by computers. Cars and jets were designed on computers, traffic signals are run by computers, most medical equipment use computers and space exploration was started with computers. Most of the jobs today require the use of computers whose 'mechanical brains' have a huge impact on our society. It would be hard if we didn't have the computer around. It is obvious, therefore, that the main trends of computer development are ‘getting smaller’ and ‘enhancing speed’. It is practicability and universality that empowers computers to be deeply imbedded into our daily lives and most fields cannot research without them. In other words, computer techniques expedite other subjects and consequently affect on human progress.

Let's visualize for a minute. Let's visualize a world without computers. People in the medical field wouldn't have found a lot of cures to diseases without the help of computers. Movies like Jurassic Park, Toy Story, A Bug's Life or Godzilla would never have been made without computers because they used computer graphics and animation in them. Pharmacies would, without the use of computers, have had a hard time keeping track with what medications to give to patience. Counting votes would be impossible without computers and most importantly, space exploration would be impossible without the help of computers. It's a pretty tough life without computers, in a word. Some may not agree and say, "Well, we don't need computers to live on." They maybe right but mostly, they are wrong. Computers help in curing diseases, create more entertainment for people, keep track of important records, and etc. Without computers, all this wouldn’t come true.


Trends in Computer Development


The main trends of computer development are ‘getting smaller’ and ‘enhancing speed’. Getting small is not only size but also the consumed power. As we know, resources are getting less, so saving power is really necessary. Some people say it is equated with saving capital. Other people say that running a laptop computer can run away with a lot of batteries. For personal laptop computers, if the consumed power is low, it means you can use your computer for a long time without changing the battery. The development of saving the power of computer and enlarging the content of the battery benefits some people who have to use their laptops in different places and don’t want to carry chargers. Enhancing speed has two meaning. One is to accelerate the speed of processing. For example, we can run lots of programmers at the same time and it will not break down. Another one is enlarging memory, which is to increase the space of saving data and transferring data.


The above paragraph is about the trend of hardware development. The following is about software. It has two aspects – operating system and application software. The operating system likes a layer to provide conditions for the application of software and connect to the hardware. Even if the hardware and software have enhanced perfectly, without an operating system they cannot work together. So operating system plays an important role in software. The application of software is associated with our daily lives. For instance, MSN is quite useful software and a more popular chatting tool on the Internet. By using it, we can see and talk to others wherever we are.
