Notebook PC
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 last achievements in the field of computers, and they are undeniably conquering more users every day. When talking about laptops, which are also called notebook computers, we actually mean small PCs for flexible use.
The typical components of desktop computers are all to be found in laptops. 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 sport 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 it of these computers. Laptops are usually 0.7 ? 1.5 inches thick and their overall size of it specifics range from 10x8 inches (13 inch display) to 15x11 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 became feasible 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.
The first laptops were available on the market only in 1981. The Epson HX-20 and Osborne 1 models were the first portable computers commercially available. Since then laptops have gained a lot in terms of proficiency.
Unfortunately, there are downsides to the use of laptops too. First we need to see the good parts to be able to investigate the flaws. The main and most important advantage of laptops is evidently their portability. In addition, laptops have the ability to work on battery power in the event of a power outage.
Laptops are also more economical and do not produce as much heat as desktop computers do. The disadvantages of laptops come from the standardization and compatibility issues. Despite of some international standards for the manufacturing the elements for the peripherals and add-in PC cards in backcloth computers, the processor and hard driver manufacturing part does not fall subject to any international regulation yet.
