Today, there are many types of computers which the people are using and talking about. Let us now know and learn their different categories: 22 Even today, large companies are still using computers for massive computing tasks and to utilize their big investments on these expensive room-sized machines.
These mainframes are housed inside an air-conditioned room in big companies to keep them in good working condition.
Even-though most of the people are not aware of their existence, most of us are really using them indirectly and benefiting from their power and capability. Like for example when we are withdrawing money from an ATM Automatic Teller Machine or depositing money in our bank accounts.
Big and large banks are still utilizing their mainframe computer for their banking operations, though these banks are using PCs Personal Computers at the same time for their other daily transactions.
Minicomputers are also like mainframes, though they are smaller and less expensive compared to mainframes.
However, they are less powerful than mainframes but more powerful than personal computers. The new breed of Personal Computes PCs which are called high-end network servers can surpass the power and capabilities of minicomputers in terms of speed, accuracy and reliability.
Most of the computers that we see and read about today are under this category. They are almost everywhere, from the comfort of our home to every office of a well-established company. The PC is also called microcomputer since it is smaller than the minicomputer in terms of its size and weight. It is also known as desktop computer, because PC always sits at the top of the desk.
They are called portable, because we can carry them from one place to another. Today, those portable computers were replaced by flat-screen and battery-powered laptop computers.
They are so light and handy enough to rest in our lap while we are working with our company memo, budget estimates or simply our e-mail to be sent when we get our Internet connections in the office or at home. In our present trend, the typical laptop is called notebook computer that weighs much less and can be carried like a book. Not only that, the palmtop computers hand-held are the fast emerging type of portable computers now.
Generally, portable computers are more expensive than their personal computer desktop counterparts. Have you seen them in the latest computer magazine today? Or to your favorite computer store? Supercomputer primarily used for scientific research that involves with the manipulation of highly complex mathematical data and equations.
These data requires trillions of operations to resolve. Physicists use supercomputers to study and analyze the results of explosions of nuclear weapons which are presently being tested.
Meteorologists use supercomputers to analyze and study the formation of tornadoes. Scientists and engineers are using supercomputers to sort through, analyze, and interpret mountains of seismic data gathered during oil-seeking explorations.
There are only few hundred supercomputers presently used in the whole world today. They perform specific tasks such as controlling the temperature and humidity in a big building offices, and to monitor the heart rate of patients in the hospital.
We may wonder how this embedded computers are being put inside our stereos, video player, or phones. Do they have keyboards, mouse, monitor, and disk drives?
What they have are the capabilities of performing tasks which are similar to personal computers. These embedded computers are usually built-in to a chip integrated circuit with a special-purpose program inside it. This program inside performs the task such as temperature control and heart rate monitoring. In other words, they are a combination of hardware the IC and software the program in one microprocessor-like packaged chip.
The program inside it is technically called firmware.
It is a small appointment book and is normally used for special applications, such as taking notes, displaying phone numbers and addresses and keeping track of dates or agendas. Smart Phone is a cellular phone with advanced features such as an Internet Web surfing capability and access to e-mails, as well as a personal organizer at the same time.
