Measurement Terms R· 1 Bit = Binary Digit · 8 Bits = 1 Byte · 1024 Bytes = 1 Kilobyte · 1024 Kilobytes = 1 Megabyte · 1024 Megabytes = 1 Gigabyte · 1024 Gigabytes = 1 Terabyte · 1024 Terabytes = 1 Petabyte · 1024 Petabytes = 1 Exabyte · 1024 Exabytes = 1 Zettabyte · 1024 Zettabytes = 1 Yottabyte · 1024 Yottabytes = 1 Brontobyte · 1024 Brontobytes = 1 Geopbyte Ram "random access memory". Basically, it gives your computer room to operate and run programs. The more random access memory you have, the faster your computer will be able to operate

First pc The first Consumer Computers 1974/75 Scelbi & Mark-8 Altair & IBM 5100 Computers 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 1 K of programmable memory, with an additional 15 K of memory available for $2760. The second "personal computer kit" was the Mark-8 (also Intel 8008 based) designed by Jonathan Titus. The July issue of Radio Electronics magazine published an article on building a Mark-8 microcomputer, information the general public was hungry for. At the same time, the Intel company introduced the new 8080 microprocessor chip, made for controlling traffic lights. It was to become the microprocessor inside the very successful Altair computer.

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 Ultra. Lite, which was the first 'laptop' computer. Weighting under 5 lbs, it was the precursor of today's models.

Virus, Worms, and Trojan Horses A computer Virus attaches itself to a program or file enabling it to spread from one computer to another, leaving infections as it travels . Worms spread from computer to computer, but unlike a virus, it has the capability to travel without any human action. The Trojan Horse, at first glance will appear to be useful software but will actually do damage once installed or run on your computer.
