This type of memory, also called main memory or RAM (Random Access Memory), is only used for temporary storage of data. When you restart a computer, it typically wipes the memory entirely. Memory wouldn't be a good place to store data for later, like files and programs. Computers store long-term data in a different type of memory: external.

You turn the computer on. The computer loads data from read-only memory and performs a power-on self-test (POST) to make sure all the major components are functioning properly. As part of this test, the memory controller checks all of the memory addresses with a quick read/write operation to ensure that there are no errors in the memory chips. Read/write means that data is written to a bit and.

computer memory, device that is used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer. Computers represent information in binary code, written as sequences of 0s and 1s. Each binary digit (or " bit ") may be stored by any physical system that can be in either.

Memory unit is the amount of data that can be stored in the storage unit. This storage capacity is expressed in terms of Bytes. The following table explains the main memory storage units −. A binary digit is logical 0 and 1 representing a passive or an active state of a component in an electric circuit. A group of 4 bits is called nibble.

You can basically use SATA with any laptop or computer, even if its a very old one. As of current, SATA 3.0 is the most versatile form of SDD and it has a transferring rate of 6Gb/s, but usually, the actual transfer speed would be 4.8Gb/s due to physical overhead. There's also SATA 2.0 apart from 3.0 as well.

Memory Hierarchy. The CPU can only directly fetch instructions and data from cache memory, located directly on the processor chip. Cache memory must be loaded in from the main system memory (the Random Access Memory, or RAM). RAM however, only retains its contents when the power is on, so needs to be stored on more permanent storage.
