Computer: an electronic device for storing and processing data,
typically in binary form, according to instructions given to it in a variable
program.
Bit: A bit (short
for "binary
digit")
Byte: 8 bits
RAM: Random
Access Memory
Character
set: a complete set of letters, numbers,
symbols, and control codes that can be used by a computer
File: A file,
in the computer
world, is a self-contained piece of information available to the operating
system and any number of individual programs.
File system:
In a computer, a file system (sometimes written filesystem)
is the way in which files are named and where they are placed logically for storage and retrieval.
Directory: A directory is another name for a folder. File
systems use directories to organize files within a storage
device, such as an HDD or SSD. For example, system
files may be located in one directory, while user files may be stored in
another.
While directories often contain files, they may also
contain other directories, or subdirectories. The user folder,
for instance, may include directories such as Documents, Pictures, and Videos.
Each of these directories may contain files and other subdirectories. This
resulting directory structure, represented visually, would look like an
upside-down tree. The top-level directory of a volume that contains all
other directories is aptly labeled the root
directory.
Hard disk
drive: Stands for "Hard Disk
Drive." "HDD" is often used interchangeably with the terms
"hard drive" and
"hard disk." However,
the term "hard disk drive" is technically the most accurate, since
"hard drive" is short for "hard disk drive" and the
"hard disk" is actually contained within the hard disk drive.
Keyboard map:
A keyboard
layout is any specific mechanical, visual, or functional
arrangement of the keys, legends, or key-meaning associations (respectively) of
a computer, typewriter, or other typographic keyboard.
Mouse: a small handheld device that is dragged across a flat
surface to move the cursor on a computer screen, typically having buttons that
are pressed to control functions.
Pixel map: is a
video display technique applicable to devices with native fixed pixels, such as LCD monitors and plasma displays
