The term computer system can refer to either the design of one computing unit itself or the system that is used to make the computer properly work. Many models of computer systems exist for a wide variety of different (приложений). Each of these models can have a wide variety of (операционные системы) to insure the computer (работать) properly. Becoming aware of these various types of computer system designs can be useful in deciding what sort of system will best suit your needs.

(Универсальные вычислительные машины) are very large and powerful computer systems made for running high-level data-(обрабатывающие) programs. These computers are accessed through terminals that consist of a monitor, a keyboard and a mouse. (Мейнфреймы) can be used by hundreds of people (одновременно), and they can (обрабатывать) and (хранить) enormous amounts of (данных).

(Суперкомпьютеры) are the most powerful type of computer system design. Very few (суперкомпьютеры) exist and are usually found in use by companies, governments and industries that process massive amounts of information, such as nuclear power or aerodynamics.

PDA is a (ручной) computer that may be used to (получать доступ к) data when you are not able to use your (ноутбук) or your (настольный) computer. Whether you are a professional, an entrepreneur or just a novice you can use the PDA technology.

You can use it in your car with a GPS for automobile navigation. Nowadays many professionals make use of PDA in medical or scientific usage.

If you are a student or even a teacher, the use of PDA can (облегчить) your work. As teacher you can now share your textbooks with your students by using internet or infrared (подключаемость).

As students you can take (в цифровой форме) notes, (загружать) homework and course material. So you can save time and render more productivity in class.
