114. Discuss the various types of computers and their applications.
Desktop computers, laptops (also called notebook computers), and handhelds are all popular both for
personal and business use. The main differences between desktop computers and laptops are their size and
portability, their motherboard, and their human-computer interface. A desktop computer comes with a separate
keyboard and monitor, and is larger than a portable laptop computer. Laptops have integrated monitors and
keyboards, and often have a touch pad. As for the differences in the motherboard, a desktop computer has
expansion slots to plug in external sound and graphics adapters and RAM modules. Upgrading a desktop
computer is fairly easy, but updating features on laptops is much more difficult. Handheld computers support
many of the features of desktops and laptops, such as word processing and Web browsing, but they have less
capacity and processing power.
Mainframes are large, high-capacity computers used by large organizations to process and store colossal
