The computer, an essential tool

A computer is more than just an electronic device. The majority of people depend on computers for their daytoday work. It is not just people who do administrative work that need computers, but also researchers, professors or artists. All of them need computers to save and generate information. The more we know about how to take care of our computer, the better it will work. Moreover, computers are used as a means for connecting with other people through the Internet. We can have long distance relationships and receive news from our loved ones who are far away. However, it is also important to remember that using a computer that is connected to the Internet is also a responsibility and it must be protected. It is a good idea to be cautious with the emails you receive or the websites you go to, as this will help prevent problems. Additionally, it is also a good idea to use ICT tools to protect your system from viruses and malware. 

UNIT 8 - The computer, an essential tool

Unit description

The computer is one of the most prolific tools ever built in the history of mankind. This electronic machine which receives and processes data in order to transform it into useful information has two distinct parts: one tangible part called hardware (keyboard, monitor, computer case, RAM memory, processor...) and the intangible software part (programs, data...) which both depend on each other to function.

The fact that it can be programmed means that a wide range of tasks can be performed; an aspect which clearly differentiates this general purpose machine from other machines with similar characteristics. Its input database can carry out operations in almost all areas of human performance known; either as a work tool or as a means of performing calculations, processing information or communicating with those around us.
