Computers are programmable electronic devices that accept data, execute prerecorded instructions, perform mathematical and logical operations, and output results.
Desktop personal computers (PCs) are small, relatively inexpensive computers that are designed for individual users. Typically, these devices include a monitor, keyboard, mouse, and other peripherals.
Information technology (IT) staffing services provide temporary or permanent workers who troubleshoot and repair computers, operate help desks, and support voice and data networks.
Kiosks and point of sale (POS) systems are used for sale processing and inventory tracking. Examples include electronic cash registers, computerized check-out systems and self-serve kiosks.
