Computer workstations are client computers that connect to a network and share data with other machines. They are used in applications such as computer-aided design (CAD), computer-aided manufacturing (CAM), graphic design, software development, medical imaging, and point of sale (POS) systems.
Computers are programmable electronic devices that accept data, execute prerecorded instructions, perform mathematical and logical operations, and output results.
Telephones and cellular phones convert voice or other sound signals into a form that can be transmitted to another device that receives and reconverts the waves back into sound.
