ABOUT LAPTOP● A personal computer for mobile use. A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (pointing stick) and speakers into a single unit.● A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery.● Also called notebook or computers.
CLASSIFICATION● Full-size Laptop- A laptop large enough to accommodate a "full-size" keyboard (a keyboard with the minimum QWERTY key layout, which is at least 13.5 keys across that are on ¾ (0.750) inch centers, plus some room on both ends for the case).● Notebook- A smaller, lighter, more portable laptop. It is also usually cheaper than a full-size laptop, but has fewer features and less computing power. Smaller keyboards can be more difficult to operate.
● Tablet PC- These have touch screen. There are "convertible tablets" with a full keyboard where the screen rotates to be used atop the keyboard, and "slate" form-factor machines which are usually touch-screen only (although a few older models feature very small keyboards along the sides of the screen.)
COMPONENT● Central processing unit (CPU)● Memory (RAM)● Expansion card● Power suppy● Battery● Video display controller● Display● Removable media
ADVANTAGES● Productivity● Using a laptop in places where a desktop PC can not be used, and at times that would otherwise be wasted.● Immediacy● Carrying a laptop means having instant access to various information, personal and work files.● Size● Laptops are smaller than desktop PCs. This is beneficial when space is at a premium, for example in small apartments and student dorms. When not in use, a laptop can be closed and put away.
DISADVANTAGES● Performance● The performance of mainstream desktops and laptops is comparable, and the cost of laptops has fallen more rapidly than desktops, laptops remain more expensive than desktop PCs at the same performance level.● Upgradeability- Upgradeability of laptops is very limited compared to desktops, which are thoroughly standardized. In general, hard drives and memory can be upgraded easily. Optical drives and internal expansion cards may be upgraded if they follow an industry standard, but all other internal components, including the motherboard, CPU and graphics, are not always intended to be upgradeable.
CONCLUSION● Portable computers, originally monochrome CRT-based and developed into the modern laptops, were originally considered to be a small niche market, mostly for specialized field applications such as the military, accountants and sales representatives.● As portable computers became smaller, lighter, cheaper, more powerful and as screens became larger and of better quality, laptops became very widely used for all sorts of purposes, by all sorts of people.
