A laptopnotebooks or simply laptop (also notebook computer or notebook) is a small mobile personal computer, usually weighing from one to three kilograms, depending on materials, size and other miscellaneous factors.
Although, some older mobile computers, such as the Macintosh Portable and certain Zenith TurbosPort models, were sometimes described as "laptops", their size and weight were too great for these categories.
Laptops usually run on a single battery or from an external AC/DC adapter which can charge the battery while also supplying power to the computer itself.

Terms sometimes used for subtypes of laptop computers include:
Thin-and-lights
Laptops usually weighing in between 1.8kg and 2.8kg with a screen size of between 12 and 14 inches diagonally. Because laptop is a portable and great machine so you are considered to “buy laptop” one for your collection !
Medium-sized laptops - cheap laptop but great in capabilities
These usually have screens of 15 - 15.4 inches diagonally and a weight of around 3-3.5kg. A more enduring success was the Compaq Portable, the first product from Compaq, introduced in 1983, by which time the IBM Personal Computer had become the standard platform. The computer could be run from batteries, and was equipped with a 320×200-pixel plasma display and 384 kilobyte bubble memory. The Gavilan was notably the first computer to be marketed as a "laptop". Among the first commercial IBM-compatible laptops were the IBM PC Convertible, introduced in 1986, and two Toshiba models, the T1000 and T1200, introduced in 1987. Later models featured an Intel 80286 processor and a 20MB hard disk drive. ZDS partnered with Tottori Sanyo in the design and manufacturing of these laptops. At the time, Compaq, IBM, Toshiba, NEC, etc. all designed and manufactured their own machines. By the end of the 1980s, laptop computers were becoming popular among business people. The first notebook computers to include hard drives were those of the Compaq LTE series, introduced toward the end of that year. By also featuring a removeable hard disk drive and floppy drive it was the first three-spindle (optical, floppy, and hard disk drive) notebook computer.
Improved battery technology. Power-saving processors. While laptops in 1991 were limited to the 80286 processor because of the energy demands of the more powerful 80386, the introduction of the Intel 386SL processor, designed for the specific power needs of laptops, marked the point at which laptop needs were included in CPU design. Early laptop screens were black and white, blue and white, or grayscale, STN (Super Twist Nematic) passive-matrix LCDs prone to heavy shadows, ghosting and blurry movement (some portable computer screens were sharper monochrome plasma displays, but these drew too much current to be powered by batteries). Improved hard disk technology. Early laptops and portables had only floppy disk drives.
