Computers are the most widely used machines in the world. Almost all activities in the world are carried out on computers. Computers have developed tremendously over the years, and there are many different types of computers available today. Some computers are general purpose computers and others are specialized.
A personal computer is simply a machine which is programmed to perform certain sequences of logical or arithmetic operations automatically. Modern computers are able to do virtually any type of operation, including word processing, spreadsheet, scientific analysis, scheduling, game playing, image processing and more. Many modern desktop models can also be used as a media player, including CD-ROM and DVD. Modern computers are also found in many different configurations, including laptop computers and mainframe computers. In the past, computers were big bulky machines which could not be used in homes or offices due to their size and weight.
There are two different types of computers: desktop and laptop computers. Desktop computers consist of the central processing unit (CPU) and the main memory board. Laptop computers, on the other hand, have a thin integrated circuit board with various components. Desktop computers are normally the most expensive type of personal computer because they are large, clunky, and require special attachments such as graphics cards and a monitor. Most desktop computers are classified according to the number of installed cores and the operating system that comes with them.
A workstation is the term given to a personal computer that is designed mainly for use at work. Workstations differ from computers because they are not used primarily for gaming. A workstation may contain a printer and scanner for scanning documents or for printing work-related materials. A workstation also has a large capacity hard drive for storing documents, data files, and applications.
A handheld computer is one that is small enough to fit in a shirt pocket and usually weighs less than five kilograms. Although handheld computers are smaller than desktop computers, many handheld computers are as powerful as desktop computers. Common examples of handheld computers include pocket-size Palm models and the smaller Treo devices. Pocket computers may also refer to PDA’s, digital cameras, and video cameras.
IBM’s personal computer, the IBM PC, is the most widely used and sophisticated of all computers. IBM’s PC models offer users the ability to conduct business tasks such as word processing, spreadsheets, data analysis, financial data processing, Internet access, and desktop related tasks such as displaying images, opening up documents, and editing text. Unlike most other personal computers, the IBM PC models have a built-in operating system. The operating system of the IBM PC models includes the IBM Object Manager, System Manager, and Programming Manager.
One of the most widely used personal computers today is the Apple Computer. The Apple Computer is different from other types of computers in that it has a graphic user interface, or GUI, which allows the user to interact with and control the computer using a mouse or a touch screen. The Apple Computer, like other computers, includes different types of hardware and software to help users conduct standard desktop activities. Some of the different types of hardware and software included on the Apple Computer include the Apple Remote Server, Apple Digital Video Adapter, and Mac Storage Server.
Research into the consumer electronics market has led to the identification of a number of common household products. Among these items are personal computers. These computers provide consumers with the ability to conduct a variety of activities that include working with spreadsheets and databases, sending email, and playing computer games. IBM’s personal computers are widely recognized as some of the most powerful and sophisticated computers available today.
