TYPES OF COMPUTERS

Computers can be classified by size. There are the large, mainframe, midrange, minicomputer and microcomputer small, divided into two categories: table (desktops) and portable (laptops and handhelds).

Conceptually all internal functions they perform identical, but at different scales.

Mainframes stand out for having high processing power and great memory capacity, and control activities with large volume of data, being quite costly. Operate in MIPS (millions of instructions per second).

The classification of a particular computer can be done in various ways, for example, in terms of:

Processing capacity;

Processing speed and volume of transactions;

Storage of information;

Sophistication of the software available and compatibility;

Memory size and type of CPU.

Microcomputers table are the most used in the general market, by meeting a multitude of applications; are divided into two platforms: PC, personal computers from IBM and Apple Macintosh. The two patterns of micros have several models, and optional settings.

Curiosities:

About two decades ago, the concept of server was those mainframes that occupied a large physical space in the company in addition to need a whole cooling system several times was no need to do maintenance on the machine. With the arrival of more robust computers and the popularity of PCs, less investment, greater flexibility and diversity of resources, many companies did dowsing (replace mainframes for microcomputers), exchanging the large for the client / server architecture.
