Small Notebook Computers
The modern world is practically based on and composed of a lot of technological inventions. We seem to be unable to do anything without technology. One of the inventions many of us cannot do without is the PC. So far laptops and notebooks are the latest achievements in the field of computers, and they are undeniably conquering more users every day. When talking about laptops, which are also called small notebook computers, we actually mean small PCs for mobile use.
We can virtually retrieve all the basic components in laptops from desktops. Thus, laptops include the display, the keyboard, a pointing device – touchpad or pointing stick, and the battery. The advantage of laptops is that they make one single unit that comprises all the other items, allowing for easy maneuvers and lots of mobility. The batteries are the main distinction and individual feature specific to laptops, but the recharging mode is carried out through an AC/DC adapter that allows extensive functionality.
The very name of notebooks comes from the thin shape and small size of these computers. Laptops are usually 0.7 – 1.5 inches thick and their dimensions range from 10×8 inches (13 inch display) to 15×11 inches (17 inch display) or up. Furthermore, laptops are built light, weighing no more than twelve pounds. The design of most laptops as the flip form factor, is meant to protect the screen of the computer when it is closed.
Personal computers were produced for the first time at the beginning of the 1970s and not long after those years the idea of portable PCs – laptops, appeared. The person who imagined this was Alan Kay of Xerox PARC. In 1972 he put his idea on paper under the name of Dynabook. By 1981, the first laptops were introduced on the market. The Osborne 1 and then, in the same year, the Epson HX-20 were the first portable computers commercially available. Since then laptops have developed and become more and more proficient.
Unfortunately, besides the obvious advantages of laptops, there are also some disadvantages. First we need to see the good parts to be able to investigate the flaws. The main and most important good bit about laptops is evidently the flexible use they are suitable for. Moreover, laptops have the ability to work on battery power in the event of a power outage. The cheapest laptop computer is also more economical and does not produce as much heat as desktop computers do. The disadvantages of laptops come from the standardization and compatibility issues. In spite of some international standards for the making of the elements for the peripherals and add-in PC cards in desktop computers, the processor and hard driver manufacturing part does not fall subject to any international regulation yet.
