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
RJ-45

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.

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.

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.

OSI MODEL(Open Systems Interconnection Basic Reference Model )
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).
