Definition for computer systems
The complete computer made up of the CPU, memory and related electronics (main cabinet), all the peripheral devices connected to it and its operating system. Computer systems fall into two categories: clients and servers.
Clients are the user's laptop, desktop and tablet computers and smartphones, while servers share their data and applications with multiple users. Servers range from entry-level rack mounts to mainframes. See rack mounted and mainframe.
A computer system is sized for the number of users it handles simultaneously, the type of work performed (office, engineering, etc.) and the volume of data that must be stored.
