This document discusses different types of computer network cables. It describes three main types: coaxial cable, fiber optic cable, and twisted pair cable. Coaxial cable contains a conductor, insulator, and sheath. Fiber optic cable transmits beams of light and is commonly used for computer networking due to its high bandwidth. Twisted pair cable, also known as Ethernet cable, is used for DSL lines, telephone lines, and local area networks. It comes in UTP and STP varieties.

2. Network cable types:
There are three types of cable. These are
1 | Coaxial Cable
2| Twisted pair
3| Fiber Optic
Coaxial cable:
This cable contains a conductor, insulator and sheath
Where coaxial cable used
Coaxial cable is commonly used by cable
operators, telephone companies, and internet
providers around the world.
Based on conductor a coaxial cable can be
categorized into two types; single-core coaxial cable
and multi-core coaxial cable.
A single core coaxial cable uses a single central
metal (usually copper) conductor, while
a multi core coaxial cable uses multiple thin
strands of metal wires.

3. Fiber Optic Cable
Fiber optic cable is a high-speed data transmission
medium. Beams of light are transmitted at a time
Fiber optics uses
Computer networking is a common fiber optics
use case due to optical fiber's ability to transmit
data and provide high bandwidth.
Twisted Pair Cable
It is also known as Ethernet cable.
Application of twisted pair cable
1| DSL lines
2| telephone lines
3| IN LAN
Types of twisted pair:

4. 1| UTP (Unshielded Twisted Pair)
2| STP (Shielded Twisted Pair)
Difference between UTP & STP cable
UTP STP
High comparatively Less susceptible to
noise and crosstalk
Not required Necessarily required
Easily installed as
cables are smaller,
lighter and flexible
Installation of cables is
difficult comparatively
cheaper Expensive
Slow comparatively Provides high data
rates
Advantages & disadvantages twisted pair
cable

5. Advantages Disadvantages
It is the smallest
amount espensive
media of transmission
for brief distances
It provides poor
security and is
relatively easy to tap
Best performances in
short distances
Low durability
High cost performance  As they a thin so
can be easily
breakable.
