ROM (read-only memory) — Non-volatile memory that can be read 
but not written to. Non-volatile here means that information in ROM 
remains whether or not the computer is receiving power. This type 
of memory is used to store your computer’s BIOS, which is 
essential instructions the computer reads when you start it up. See 
also BIOS, memory. Compare RAM.
S

used to store and transfer data between digital products, providing 
encryption capability for content security.

intent to perform some operation on it.
serial — Processes that occur one at a time. In communications, it means 
the transmission of one bit at a time sequentially over a single

solid state drive —A data storage device that utilizes solid-state memory

for storage of programs and data.

 operating system, 
generally a drive letter followed by a “greater than” sign) indicating
