Computer Architecture
CPU – Central Processing Unit: Is a microprocessor. Contains a control unit, an ALU / Arithmetic Logic Unit and primary storage. Instructions and data are held in the primary storage unit needed by the CPU. The primary storage is a temporary memory area to hold instructions that are to be interpreted by the CPU and used for data processing.
Buffer overflow – Data being processed is entered into the CPU in blocks at a time. If the software instructions do not properly set the boundaries for how much data can come in as a block, extra data can slip in and be executed.
Real storage – As instructions and data are processed, they are moved back to the system’s memory space / real storage.
