External memory algorithm
In computing, external memory algorithms or out-of-core algorithms are algorithms that are designed to process data that are too large to fit into a computer's main memory at once.

The model captures the fact that read and write operations are much faster in a cache than in main memory, and that reading long contiguous blocks is faster than reading randomly using a disk read-and-write head.
Data cluster
Unit of disk space allocation for files and directories.
Unit of disk space allocation for files and directories.
However, a larger cluster size reduces bookkeeping overhead and fragmentation, which may improve reading and writing speed overall.
Memory refresh
Process of periodically reading information from an area of computer memory and immediately rewriting the read information to the same area without modification, for the purpose of preserving the information.

As a consequence, the memory controller typically added a refresh cycle after each read cycle in order to create the illusion of a non-destructive read operation.

Pakistani-American electrical engineer.
He was a visiting researcher at HP Labs for a year in 1989, during which time he investigated A/D conversion at ultra-high speeds, before returning to UCLA and researching analog signal chains for disk drive read channels, high-speed A/D conversion, and analog CMOS circuits for signal processing and communications.

In 1984, Cioffi left Bell Labs to work at IBM as a hard disk drive read channel researcher.
Asynchronous communication mechanism
The role of an asynchronous communication mechanism (ACM) is to synchronize the transfer of data in a system between a writing process and a reading process operating concurrently.
