5 Major Pieces of Hardware The most important piece of hardware on your PC is your motherboard. Without it nothing can be used. The second most important is the CPU. It is like the brain of the PC, a motherboard can't run without it. Then it comes RAM. RAM is the memory that the computer uses to run, without RAM you won't be able to install any operating system. Then comes the keyboard, without it you can't install an operating system to the PC, and you won't be able to tell the PC what to do. And also a monitor is needed, to display everything you're doing.

The First PC In the March, 1974, issue of QST magazine there appeared the first advertisement for a "personal computer." It was called the Scelbi (SCientific, ELectronic and BIological) and designed by the Scelbi Computer Consulting Company of Milford, Connecticut. Based on Intel's 8008 microprocessor, Scelbi sold for $565 and came with 1K of programmable memory, with an additional 15K of memory available for $2760. The second "personal computer kit" was the Mark-8 (also Intel 8008 based) designed by Jonathan Titus.

The First Laptop The laptop was invented by Adam Osborne in 1981. It was called 'Osborne 1' and cost $1,795. It came bundled with $1,500 worth of programmes. It had a tiny computer screen built into it. It was invented by Osborne Computers. The first portable computer was a success, with sales reaching 10,000 units a month. IBM launched the IBM 5155 Portable Personal Computer in 1984. In 1988, Compaq Computer launched the first laptop PC with VGA graphics, Compaq SLT/286. In 1989, NEC released UltraLite, which was the first 'laptop' computer. Weighting under 5 lbs, it was the precursor of today's models.

Virus, Worms, and Trojan Horse Macro viruses: A macro is a piece of code that can be embedded in a data file. Worms: Worms are very similar to viruses in that they are computer programs that replicate functional copies of themselves. Trojan horses: A Trojan horse is a program that does something undocumented which the programmer intended, but that users would not accept if they knew about it.
