A study on purchasing behavior among UiTM Sabah students (Full Time) towards laptop / Nas Norniza Nasbah

A laptop computer or simply laptop (also notebook computer or notebook) is a small mobile personal computer, usually weighting from one to three kilograms, depending on size, materials and other factors. While the terms "laptop" and "notebook" are often used interchangeably, "laptop" is the older term, introduced in 1983 with the Gavilan SC. "Notebook computer" is a later coinage, which was used to differentiate smaller devices such as those of the Compact LTE series in 1989, which were in contrast to previous laptops, the approximate size of an A4 paper sheet. Either term often used improperly; due to heat and other issues, may laptops are inappropriate for use on one's lap, and most are not the size of an A4 sheet. Although, some older portable computers, such as the Macintosh Portable and certain Zenith TurbosPort models, were sometimes described as "laptops", their size and weight were too great for this category. 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.
