Mathematics is essential to computer science and information technology in several ways: 1) Early tools like the abacus helped humans perform calculations, while analytical engines designed by Charles Babbage introduced the concept of the central processing unit that powers modern computers. 2) Computers understand binary language and use logic and arithmetic operations like addition, subtraction, multiplication and division to process data and perform comparisons. 3) Mathematical concepts like binary representation, IP addressing in decimal or hexadecimal, and cryptography techniques using permutations and combinations are crucial for data storage, transmission, and security.

How Did Mathematics Popup Into
Computer / InformationTechnology
Applications & Role !!

5. ABACUS
▪ The abacus was an early tool
for mathematical computation.
Second bullet point here
▪ It helps the memory of human
performing the calculation.
▪ Useful only for adding and
subtracting of numbers.

6. Analytical Engine
▪ Charles Babbage a.k.a “Father
Of Computer” Designed & Built
it.
▪ It is the brain behind the
computer we use today (CPU).

7. Binary / Machine Language
▪ Computer Understand the Binary
Language.
▪ Compiler is used to Communicate
with the Computer.

8. The Arithmetic / Logic Unit
▪ The arithmetic/logic unit can perform
four kinds of arithmetic operations i.e.
mathematical calculations : addition,
subtraction, multiplication, and division
▪ • A logical operation is usually a
comparison
1. Equal-to condition “=“
2. Less-than condition “<“
3. Greater-than condition “>”

9. Data Packets
▪ A packet is the unit of data that is routed between an origin and a
destination on the Internet .
▪ The are in the Binary Form.

10. IP Address
▪ An IP or Internet ProtocolAddress is a numerical label assigned to
each device connected to the Internet .
▪ The are Displayed in Decimal Form / Hexadecimal.
▪ Converted to Binary Form.

11. Cryptography
▪ Cryptography is nothing but Security of Data . The are in the Binary
Form.
▪ They use the Permutation & Combination to achieve Security.
