Although the computer may be the same for many trades, it is necessary to take into account what programs will be emphasized (accounting, text, graphics, image processing, etc.) You should also know that some computers have the ability to grow in features: More RAM, adapting a modem to send long-distance information to another user, sound card, external hard drives and many more possibilities.

In addition, with 4 Megas of RAM memory will be enough, although most manufacturers are launching their basic models with 8 megs. The capacity of the hard drive will be the least, with about 80 megs, because the documents will not take up much space and you will always have the possibility to save the old works on a floppy disk.

For researchers there are professionals like mathematicians, engineers, architects, chemists, etc., whose work does not require personal computers, because they do not come to meet the requirements that their daily work requests, but they need what is called Workstations, due to the heavy operations they need to perform with them and the amount of information or data they need to store and process.

For illustrative artists, architects, video operators or advertisers will require larger screens, which reproduce the image and color as faithfully as possible.
