Understand what a personal computer is

  • A laptop computer is a portable computer designed to fit inside a briefcase — many laptops are approximately 12” (30 cm) wide by 9” (23 cm) deep by 2” (5 cm) high, although sizes do vary.

  • Modern laptops have most of the features and components available on PCs, and offer the same level of flexibility in performing a wide range of tasks.

    However, the size of a laptop makes it more difficult and costly to develop, so laptops tend to be more expensive, and generally have less processing power and storage capacity than desktop PCs.

  • A laptop has a built-in screen and keyboard. This is one of the main reasons why a laptop is so portable. The screen is usually a Liquid Crystal Display (LCD) less than 1 cm thick. The screen is usually the most expensive part of a laptop. It is increasingly common to find laptops with cameras and microphones in-built.

  • Laptops tend to be used by people who do a lot of travelling in their job, and need to be able to process and store information wherever they are (and whether or not they have a power source available). Examples would be sales representatives, consultants and support engineers who need to travel to different sites. These days many people have laptops just because of their convenience.
