The document discusses different number systems used in computers such as binary, decimal, hexadecimal, and octal. It explains how computers use binary digits for operations and how different number systems are converted between each other. For example, binary numbers are converted to decimal by multiplying each bit by its place value and summing the results. Negative numbers are represented using ones' complement and twos' complement in binary. Basic logic gates and flip-flops used in digital circuits are also introduced.

What is electronics?
Electronics is the science of how to control electric energy, which the electrons have a fundamental role.
This presentation gives a brief explanation about what is electronics and each of the part of the electronic components.

A computer understands
information composed of only zeros and
ones.
The decimal number system is
convenient for the programmer.
The computer uses binary digits for its
operation.

SIGNED ARITHMETIC OPERATION
MSB bit is reserved to represent the sign of
the number.
When the number is negative, the sign bit is
kept one.
When the number is positive, the sign bit is 0.
In 8-bit processor, MSB = sign bit & other 7
bits = number.
In 16-bit processor, MSB = sign bit & other
15 bits = number.

LOGIC GATES
Logic gates perform basic logical functions.
They are fundamental building blocks of
digital integrated circuits.
Most logic gates take an input of two binary
values, and output a single value of a 1 or 0.
Some circuits may have only a few logic
gates, while others, such as microprocessors,
may have millions of them.
There are seven different types of logic gates,
which are outlined.

FLIP-FLOPS
A flip-flop or latch is a circuit that has two
stable states and can be used to store state
information.
Each flip-flop stores one bit of information
