partition

Process of dividing mass storage (hard disk drive) into isolated or separate sections.
Partitioning a hard drive creates additional logical drives, e.g., a 5.1-GB hard drive
partitioned into three logical drives creates drives C, D, and E. Partitioning facilitates
file management by allowing you to isolate the computer’s operating system to drive C
while storing applications and data files on separate drives D and E (also referred to as
partitions).

password

A string of characters that the user must enter before the system allows access or
system privileges.
