1. Overview of Ethernet Hardware and
Protocol
By www.shopricom.com

2. Ethernet
Ethernet was developed
at Xerox Palo Alto
Research Center, with a
motive of connecting
several computers
together in a network. It
is widely used in LAN
technology .It supports
data transmission rate
of 10 Mb/s. Now a days it
has been extended up to
100 Mb/s and 1 Gb/s.

3. Ethernet works in
the physical and
data link layer.
Physical and Data
link layer is
present at 1st the
2nd position of the
Open Systems
Interconnection
(OSI) model .

4. Ethernet
uses bus or
star
topology

5. To make proper utilization
of Ethernet we need to have
Ethernet hardware and
Ethernet protocol both. The
upcoming slides will provides
you the details regarding it.

6. Ethernet Hardware
It can be classified into three parts.
They are listed below
(i)Ethernet Card or Adapter
(ii)Ethernet Cable
(iii)Ethernet Hub

7. Ethernet Card or
Adapter: It is the
card which is
installed in each
PC. Computer uses
this card for
sending data
across the network.
It is connected to
the computer via
Ethernet cables.
IBM 10GB Ethernet
is one of the most
effective adapters.

8. Ethernet Cable:
It consist of
numerous wires. It
is capable of
transferring data
in both the
direction to and
from the computer.

9. Ethernet Hub:
It helps to connect
several computers
together in a network.
It has multiple ports.
To form a single
network segment
firstly it connects
Ethernet cable into
the unit, and then
joins the other end of
the cable to each
computer's NIC.

10. Ethernet Protocol
It consist of three main
components, such as Ethernet
frame, the Physical Layer and
the MAC operation.

11. Frame
Structures
Ethernet Frame
The data packets need to
be send throughout the
network is known as
Ethernet frames. The
above diagram
represent the structure
of a Ethernet frame.

12. Physical
Layer
The Physical layer is
responsible for encoding,
decoding, and synchronizing
the data which is required to be
transfer across the network.

13. MAC Operation
Ethernet uses CSMA/CD (Carrier
Sense Multiple Access with Collision
Detection) protocol. It helps to detect
collision between several
transmitting stations. CSMA/CD
listen to the network carefully before
sending any data packets. If any
collision occurs, a jam signal(which
is 32­bit binary pattern sends by a
data station)is send to alert other
stations. After a time interval the
process continues smoothly.
