NETWORK DEVICES

Lan card:-

The network interface card(NIC)
used as interface between the
device and the network.
It has Buffer memory.
Memory of LAN card is 1024 byte.
Lan card is used for both
transmission and receiving of data
MAC address is physical or
hardware address.
Size of MAC address is 48 bit

Hub




Hub is a layer 1physical layer
device.
Hub provides data transfer rate
(D.T.R)= 10 mbps maximum.
Hub works on half duplex mode
Hub is used over a small LAN
network.
6
Switch






Switch is a layer 2(data link
layer) device.
Switch is a LAN device.
Switch understands MAC
address.
Switch is used to design a large
and complex network.
Switch improves network
performance and speed.
Switch works on full duplex
mode i.e both sending and
receiving data at the same time.
7
ROUTER

It is used for wan connectivity.
 Router is a layer-3 (network layer)
device.
 Routers are used to interconnect
different wan sites.
 Router is a IP and routing
enabled device.
 Router only understands
logical address i.e IP
address.
 Router uses a routing table
which maintains shortest and
best path for each
destination.

7) Application : Provides
different services to the
applications
6) Presentation : Handles the
format of different applications
and files
5) Session
: Responsible to
make logical connection b/w
application and server
4) Transport : Provides end to
end communication control
3) Network
: Routes the
information in the network
2) Data Link : Provides error
control between adjacent nodes
1) Physical
: Connects the
entity to the transmission media

IP ADDRESS




An Internet Protocol (IP) address is a numerical identification (logical
address) that is assigned to devices participating in a computer network
utilizing the Internet Protocol for communication between its nodes.
Although IP addresses are stored as binary numbers, they are often
displayed in more human-readable notations, such as 192.168.100.1 (for
IPv4), and 2001:db8:0:1234:0:567:1:1 (for IPv6).
IP address was defined as a 32-bit number and this system, now named
Internet Protocol Version 4 (IPv4) , a new addressing system (IPv6), using
128 bits for the address An IP address is designed with two parts:Network:- net-id
host:- host-id

Different classes of IP version 4



Class A:- 8 bit for network and 24 bit for host. First block consists of Network bits
from 1-126. Mask value is 255.0.0.0
Class B:- 16 bit for network and 16 bit for host. First block consists of network bits
from 128-191. Mask value is 255.255.0.0
Class C:- 24 bit for network and 8 bit for host. First block consists of network bits
from 192-223. Mask value is 255.255.255.0
Class D:- It is used for video conferencing . First block consists of network bits from
224-239.
Class E:- It is used for voice conferencing . First block consists of network bits from
240-254.
Special IP(Reserve IP):127.0.0.0:- This IP is called loopback or local host IP. It is used for self testing or
trouble shooting. Its command is C:> ping 127.0.0.1
255.255.255.255:- This IP is called Broadcast IP and used in lan broadcasting.
169.254.0.0:- It is called APIPA(automatic private IP address).


Route
Uses a route that a
network administrator
enters into the router
manually
Dynamic
Route
 Uses
a route that a
