Learn to use the computer

Many people use the PC every day to connect to the network and to work but without knowing what the computer is and wondering how this is possible. We put a computer to work every time we buy with a credit card, withdraw from an ATM, pay a postal order, buy a train ticket, play video games and many other things. Understanding how the PC works inside is too much but starting from its components and the origins of  IT is already a good start.

Basic computer components

The computer is made up of several electronic components on printed circuits that interact with each other via micro pulses; if you want to learn how to use the computer, the main components of a PC are:
  • A central processing unit (CPU); the "processor" used to process active processes on the data before outgoing transmission.
  • RAM memories (random access memory) in which the bytes for processing are loaded; it is the dynamic memory of the computer and it is volatile;
  • A graphics processing unit (GPU).
  • ROM memory (read only memory); "permanent" read-only, it has a fixed content that cannot be deleted and therefore is not volatile; it contains the instructions that the CPU must load to allow the system to boot and the basic routines called BIOS (Basic I / O System);
  • the Cache; or in English Memory cache characterized by high speeds and has the function of accelerating accesses to the main memory by increasing the performance of the computer.
  • mass memory; the hard disk also known as hard disk, in English Hard disk performs the function of file storage.

The origins of computer programming

Modern computers can process large amounts of data. Before the current computers we can only refer to the analytical machine of Charles Babbage; This machine performed calculations thanks to the rotation of gear wheels. Countess Ada Lovelace participates in the creation of Charles Babbage's analytical machine by decoding the language to make it work; US Department of Defense dedicates the ADA programming language in the name of the Countess.  The role of women in computer science  Apparently, the position of women in the history of computer programming seems to cut out only a marginal role; in reality, it is not so! As already mentioned in the previous paragraph; without the contribution that Countess Ada Lovelace left to the world of information technology; this science could be decades behind. The origins of computer programming languages  The origins of programming languages were determined by a mechanical and mostly experimental approach; with reference to the an...
