Application Software : To solve a specific problem, or to provide generic tools for end user
OS : Provides a wide range of functions that assist in program execution
Compiler : To translate the program into a form suitable for execution
Multiprogramming : The key OS technology that implements multiple abstract machine
Resource allocation : The OS's obligation to prevent unauthorized access of resources by one abstract machine
Batch Systems : Handle collections, or batches of jobs
Timesharing Systems : Supports multiple interactive users
Kernel : The part of OS that executes as trusted software
Communication Devices : Combination of input and output devices
CPU : Performs computation on the data, producing new data that is stored in the primary memory
ALU : Performs all arithmetic operations
PC : Contains the memory address of the next instructions the control unit is to load
IR : Contains a copy of the current instructions once it has been fetched from the primary memory
Device Controller : Connects the device to the computer's address and data bus
DMA : Able to read and write information directly from/to primary memory with no CPU intervention
POST : A set of diagnostic programs that test that particular manufacturer's hardware before any other software is installed
SIMD : Designed to execute a single program as if it were a single thread process
NOW : A loose federation of conventional personal computers and workstations interconnected with a network
Data Buffer : A region of a physical memory storage used to temporarily store data while it is being moved from one place to another
Interrupt Handler : A callback subroutine in microcontroller firmware, operating system or device driver whose execution is triggered by the reception of an interrupt
