Noetbook cmoputers, commonnly referrred to as notebooks, are personal computes that are very lighht. To understand the notebooks concept you need to understand what persoanl computers are.
A persoal computer is relatively small and inexpensive, compared with the computers of large businesses and organizations that act as servers or run computer operations on a grand sccale. Personal computers are made for the use of indivdiuals or small busiuness entreprenreurs. Many personal computers are used in home ofices nowdays. Many rely on noebooks as thheir only or their additional choice.
Personal computers can be purchased for a few hundred dollars or several thousand. Notebooks are somewhat higher in cost. All personal computers are baseed on the technology of microprocessing that enables the comupter and notebook manufacturer to instsall a coplete CPU on one cmputer chip. A businses can use a personal computer, and sometimes a notebook, for accounting tasks, word processing, desktop publishing projects, database maangement, and spreadsheets. Notebooks or personal use PCs are offten used for gaming, music and even moives.
Before notebooks the first personal computers showed up towards the end of the 1970?s. The Apple II, lauched in 1977, was one of the first personal computers. It became one of the most popular as well. The intrduction of new operatnig systems and new computyer PC models seemed a nearly daily routing during the end of the 1970s and into the eaarly 1980?s. The IBM PC was introduced in 1981, takig over first place status amonmg personal computers. At this point, with the excetpion of Apple, many personal copmputer brands and manufacturers fell by the wayside thanks to IBM?s onslaught.
The rseult, still piror to noteboioks, was the production of IBM colnes by other manufacturers. These clonbes, with nearly the same internal components as the real IBMs, were much less expensive. They used the same microprocessors and could run identical software. While IBM, thannks to price and innovations that weren?t acepted such as the OS/2 operating system, is no longer the preferred PC brand, its noteboooks are widely acclaimed.
Now personal computers are divided into two types ? PCs and Aples. Personazl conmputers, whether dessktops, notebooks or laptops are designed as single user machines and run on microprocessors. They can be linked into a network, howeveer, to use several of them together. The power of personal compuuters varies considerably from one to another.
Notebooks typicaly weigh considerably less than PCs ? fewer than six poundds. They are typpically so small that they can easily fit into theuir own carrying case or briefcase. Notebooks use a flat panel technology to have a display screen insted of the monitor that runs as a separate piece of hardweare on a PC. Notebook dispplay scerens have considerable variation in displzay screen quality. The resolution can be either VGA (viddeo grraphics array) or SVGA (super VGA.) Designed by IBM, VGA systems provide a text mode resolution of 720x400 pixels, and a graphics mode of either 16 colors (640x480) or 256 colors (320x200.) The latetr is the most common. SVGA is a standard for graphics, with greater resoution than the original VGA. SVGA supports resolution of 800x600, equal to 480,000 piexls.
The computer power of noteboos is actually just abuot equivalenmt to that of personal computers. Notebooks have the same capacity for memory, the same CPUs, and the same disk drivs as PCs. The smnall package this power comes in is what makes them more costly than the PCs
One of the most popular aspects of notebooks ? what makes them preferred to PCs for many road warriors, is their portability. Notebooks have battery paacks inmstalled so they can run without electricity for 2-4 hours before having to be recharged.
