Document Summary

Part of the computer that actually runs programs. Assembly language (low-level language): uses mnemonics instead of binary numbers. Assembler: a special program used to translate an assembly language program to a machine language program. Allows creation of powerful and complex programs without knowing how the cpu works. Allows creation of programs without writing large numbers of low-level instructions. Uses words that are easy to understand. Where computer stores a program while it is running, as well as the data that the program is working with. Volatile memory used for temporary storage while a program is running. Contents of ram are erased when computer is turned off. Memory that can hold data for long periods of time, even when there is no power to the computer. Stores data by magnetically encoding it onto a spinning circular disk. Most common type of secondary storage device. Solid-state drive: store data in solid-state memory. Usb drives: store data in flash memory.
