What is a computer?
In a word, a computer is an electronic computer.
The main task of the computer is to help us, the people. These machines accelerate the implementation of the tasks – they consider, calculate, control, calculate and act for us. A computer performs many actions instead of a person, thereby speeding up the processes and making life easier for us.
With the help of a computer, the automation of the production process is carried out; this markedly reduces the cost of production, therefore the cost of the goods decreases. The task of the computer is the solution of the most complicated mathematical operations, help in managing and creating various projects. Many people have the opportunity to earn money with a computer. This machine is a great assistant both in technical issues and in the implementation of creative ideas.
The computer has the ability to save a huge amount of information and allows you to work with it – edit, print, receive and send various data.
Initially, computers occupied entire buildings and rooms. They performed the functions of computing devices – they made mathematical calculations. Science has gradually evolved, progress has gone forward and now the computer is placed in our palm. And the scope of their use has increased thousands of times. We are used to computers and can’t imagine our life without them. But it is necessary to back up with some miracle of computer technology kazal 10 years ago. Constantly produced new models with large and large capabilities, the old ones lose their value and become cheaper at times. Today, the technology market is developing very fast, science provides new opportunities. Unseen technologies have already been invented and are waiting for their implementation. The achievements of scientists gradually appear in our life, we always want something new and, of course, the best. Therefore, we constantly get new items, even knowing that in a year it will become obsolete.
Someone can no longer imagine life without a computer, while others are not so necessary. All people at different levels own a computer. It also depends on the area of work of the person. Everyone has a choice – use the technique and save their time or trust only their knowledge and hands. A significant role in our life is played by the human factor, so it can be argued that it will perform the task more precisely – a computer or a person.
At the moment, the computer has 3 of the most common varieties.
The first is a personal computer. It consists of a system unit, a monitor, a keyboard and a mouse. Most people have such computers at home.
The second is a laptop or laptop computer. Such a machine, compared with a personal computer, is much smaller, looks like a large book and includes all the component parts of a home computer.
The third is a handheld or pocket pc. This is a very small computer that fits in your hands and is distinguished by its compactness. They are most often used for work on the road and fast access to information.
A computer consists of many parts, each of which is responsible for certain actions. The speed of the computer is determined by the main processor. Your documents — files, folders, photos, pictures, music, movies, and programs — are stored on a hard disk embedded in a computer. There is also RAM – it depends on the speed of the computer, i.e. how fast it will open applications, respond to actions and perform tasks assigned to it. The keyboard, as well as the mouse are needed to enter information and control the computer. To operate the computer you need a control program. It is called the operating system. Windows is the most common and used in everyday life, but there are others, such as Linux, MS-DOS, ReactOS, Ubuntu, Mac OS.
The computer serves as a means of quickly transmitting information using the Internet. Also, information can be stored and transferred to each other using disks (CD, DVD), flash drives, memory cards and portable hard drives (for a large amount of information).
There are many computer configurations, each of them has special features and different capacities. Choosing a computer, decide for what you will use it, since paying too much for power that will not be used is stupid. You need to choose exactly what will be convenient for you and suitable for your type of activity.
Use computers, this latest technology, as it only helps you in solving problems, translating ideas and searching for information, but do not forget about precautionary measures. A computer is not a luxury, but your assistant.
