Computer Internals	Computer A machine that processes data under the control of a stored program Operating System A set of system software routines that interface between an application program and the hardware A Program A series of instructions that guide a computer through a process The processor Manipulates the data stored in memory under the control of a program stored in the memory Optional Video Review Computer Organization - the Central processor 13 minute video. Arithmetic and Logic Unit Executes the instruction in the instruction register OS User Interface Functions that provide support for the user and application programs to communicate with the OS OS File Management Functions that provide support to manipulate files by names OS Device Management Functions that provide support for peripheral devices to communicate with the OS OS Communication Services The operating system functions that support communications between computers OS Memory Management The operating system functions that manage memory space OS Process Management The operating system functions that manages the processor's time Cache An area of high-speed memory that sits between the processor and primary memory; memory that serves as a staging area for the processor; A buffer Temporary memory or storage used to adjust for the speed differences between adjacent devices. Word A group of bytes (usually 4 or 8)
