Document Summary

The cpu is composed of several hundred million transistors. These are basic electrical components which alter and send electrical currents and signals. Secondary storage: provides slower and less expensive storage, persists without electricity, usually hard disk and solid-state drive, hard disk rotating platters, coated with magnetic material, solid-slate drive electronic components, retains information without electricity. Computers store both data and programs, located in secondary storage and loaded into memory when the program is executed. When programs are executed, it is brought into memory for the cpu to read. The cpu runs the program 1 instruction at a time and may react to user input. For instance, the keyboard interacting with microsoft word to produce letters on the screen or using the mouse to move the cursor to a new location. The main use of peripherals is to interact with human users.
