2. Introduction of ICT
Information & Communication Technology(ICT) includes
various technologies like computers, the internet, and
mobile devices that enable efficient data processing,
communication, and information sharing. It helps in
communication, access to information, and various
industries while also posing challenges related to
cybersecurity, privacy, and digital literacy.

3. Signals and their types
 Analog Signal :
Analog signals are continuous, varying in
amplitude and time.
 Digital Signal :
Digital signals are discrete and represent
information in binary code.
Signals are physical or electrical
representations of information.
They can be classified into three
main types: analog signals and
digital signals.

4. Bits and
Bytes
A bit is the smallest unit of
data that can be stored or
processed.
Bits
Bytes are used to
measure storage capacity
and data transfer rates.
A byte, consists of 8 bits and is
used as a basic unit for
representing and manipulating
data in computer systems.
It represents a binary value of
either 0 or 1.
Bytes

5. Transmission of Digital
Signals
The transmission of digital signals involves sending discrete, binary
data over a communication channel. Digital signals are encoded as a
series of 0s and 1s, representing the "off" and "on" states of the signal,
respectively. These signals can be transmitted using various methods,
such as electrical wires, fiber-optic cables, or wireless transmission. The
signals can be encoded, modulated, and transmitted in a way that
ensures accurate and reliable communication, allowing for the transfer of
data over long distances with minimal loss.
