Virtual Storage Access Method (VSAM) is a highly efficient access method and data set structure, which builds and maintains data through a catalog structure and employs a virtual storage concept and protect datasets at multiple levels by giving passwords. VSAM can be practiced in COBOL programs like in sequential files and are the logical datasets for filing records. And also, files can be read sequentially and randomly in VSAM and is an enhanced way of storing data that succeeds in the limitations of traditional file systems like sequential files.
A microprocessor is an electronic part used by a computer and is a central processing unit on a unique integrated circuit chip comprising millions of small elements including transistors, resistors, and diodes that run together. Microprocessors help from commanding elevators to search the Web.
Microprocessors were developed in the 1970s for control in embedded systems. Some microprocessors are called microcontrollers, so small and cost-less that they are used to control products like flashlights; few especially powerful microprocessors are employed in personal computers.
