RAM
memory is required to store the data or any information.but the usual computers have very less memory space in them. so to increase the performance of your computer and to access it on a faster rate we need memory hierarchy.
RAM (Random Access Memory).
Processor registers occupy the top most position in memory hierarchy. They provide high-speed storage space and fast access to data.
A data is known as the rowfact which is stored in computers memory and used by the user as the output
explain the logical& physical memory
Memory hierarchy measures a computers performance issues. A general hierarchy would reflect the following. Internal ; processor registers and cache, main; ram and controller cards, on-line mass storage and online bulk-storage.
Before computer memory chips and memory sticks were invented, floppy discs were used.
What is measured in most sources of computers,andtells you how much memory you can hold.
A record is the largest unit of information in the data hierarchy. The smallest unit in the data hierarchy is called a data field.
A memory map table is a data structure that associates ranges of memory addresses with specific hardware devices or memory locations. It provides an organized way for the operating system to manage the various memory resources available in the system. The memory map table helps determine where data should be stored or retrieved in the computer's memory hierarchy.
The key task of a memory system is to memorize data in such a way as to have it readily available to the user. This is why computers have RAM (Random Access Memory).
ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing.
