Interestingly, here we remember the days of computer science in schools where computers only began to emerge. More precisely, they were not so much in the world, how many of them have started to equip the classrooms of computer science. So, in these lessons, frequently asked homework. Perhaps the teachers had already thought that each student has a computer at home. In addition, the school - it is not an institution, it is rare to see the extra-curricular activities, and after school, you have no one to let Informatics cabinet. Another thing in the universities and institutes. If you asked your homework on the computer, but the computer you have at hand is not present, you can go up to your teacher and ask him to work on the computer. So, the presentation of many of you do, but the minimum level, which was a simple text and simple line, which does not stand out.
Believe that in companies where you may be asked to make a presentation, such skills is not enough. Naturally, you can try your hand in the standard program, which is equipped with an OS Windows. I think it's called Microsoft PawerPoint. Yes, it is the most simple, but the presentation of it obtained sufficiently simple. Another thing is that the Internet may even create presentations online. The fact is that on the Internet you can find additional, auxiliary tools, but do not think that in them you can create charts, etc.
Sometimes, high-quality presentation is derived from the finished materials. That is, you are doing well in advance, all tables, text, translate them into electronic form, and then only because of some of the program is it all in a bunch. In principle, you can create these sketches on the computer, if you have experience with such programs like Paint, PhotoShop, Coral or the other. Do not forget that standard, simple presentation, no one will appreciate. Yes, and do not need to burden their children with some effects, as important for the viewer - is information that lurks in all of these pictures.
