CCOMPROG Flashcards
This DOS Command used to clears all
the information from the screen when
you are working at the command
prompt.
CLS
which is signed
binary digit is considered positive
if the leftmost bit is always equal
to zero (0).
Number System
are useful to
describe values on a scale that
goes below zero.
Negative Numbers
These commands specific to DOS the
exact action you want to take as well as
any special information needed to carry
out your request. You use DOS prompt to
enter DOS commands.
Command Prompt
define a particular value
that is commonly known as a data item
that can treat a group of one or more
related bytes as a unit of data.
Related Bytes
This command creates a subdirectory
using the name you provide preferably
eight (8) characters long and must start
with a letter.
MD
This DOS command let you removes a
specific subdirectory, Make sure that
subdirectory is empty.
RD
allows the standardized I/O
hardware of the computer manufacturers
such as keyboard, printers, monitors and
other devices. It also provides 256
characters including symbols for foreign
alphabets for 8-bit ASCII
American Standard Coded for Information Interchange
is the fundamental building block of

Bytes
was typically served
