COMPUTER
A computer is an electronic device that
manipulates information, or data. It has
the ability to store, retrieve, and
process data. It is the most complex
machines that have ever been created.

Decimal
number system
is the numbers are represented
with base 10. It is also called the
base-10 number system which
consists of 10 digits, such as,
0,1,2,3,4,5,6,7,8,9.
Decimal
number system
• entering number into a
computer, you generally use
• Important in programming
languages. (Python, Java)
BINARY
number system
Computers can only understand two
digits - a O and a 1. This type of
number system is called the binary
number system, with the prefix bi,
which means 2.
BINARY
number system
• Storage of data
• Arithmetic Operations
• Logic Operations
• Memory Addressing
• Communication Protocols
• Machine Instructions
Octal
number system
has its base as ‘eight’. It uses numbers
from 0 to 7. As we said, any number
with base 8 is an octal number like , , ,
etc.
Octal
number system
• File permissions
• Representing machine code
instructions
• Debugging
HEXADecimal
number system
has a base value equal to 16.
Represented by only 16 symbols.
These symbols or values are 0, 1, 2, 3,
4, 5, 6, 7, 8, 9, A, B, C, D, E and F.
HEXADecimal
number system
• Memory addresses in computer
programming
• Used in Color codes
How Computers
Interpret Data
Using the ASCII table, convert the
following binary coded message into a
word : (40 pts)
0100 1001 0110 0000 0110 1101 0101
0010 0110 0001 0111 0100 0110 1001
0110 1111 0110 1110 0100 0000 0110
