TCP/IP
It is a multiplatform protocol used for both internet access and local area network.(transport control protocol/internet protocol)
WHAT IS AN IP ADDRESS?
IP (internet protocol) in lecture IP address is a 32 bit addressing system of computers which is used to create an unique identity to a computer in network. here there are some of services which was work in behalf of IP:
*ISP(INTERNET SERVICE PROVIDER
*HTTP(HYPERTEXT TRANSPHERE PROTOCOL)
*SSL(SEQURE SOCKET LEVEL)
*TLS(TRANSPORT LAYER SEQURITY)
*HTML(HYPERTEXT MARKUP LANGUAGE)
*FTP(FILE TRANSPHERE PROTOCOL)
*TELNET(TEXT COMMUNICATION)

NETWORK TOPOLOGIES
TOPOLOGY is the physical arrangement of a group of computers in order to make effective connection or network. According to the needs and preference topology is mainly classified into 4.
Ø BUS
Ø STAR
Ø RING



Ø MESH(PEER TO PEER)

v BUS topology is generally made by sharing a common cable of 10base2 or 10base5 cables serially.
v Star topology is made with the help of a switch or a hub with distributes the connection or network using 10baseT or 100baseT and 1000baseT cables
v Ring topology uses a logical ring of computers using token ring connection
v Mesh topology is used to connect directly to every other computer with the help of multiple network cards.

ETHERNET AND INTERNET


Ethernet is the network of computers in same geological area and Internet is the connection of computers of different geological area.







“WHAT IS NETWORK?”
NETWORK IS A ARRANGEMENT OF COMPUTERS OR ELECTRIC EQUIPMENTS EXPETIALY FOR THE INTERCONNECTION AND DATA TRANSPHERE FOR MEANINGFULL PARPOUSES.
Mainly two types of networks are there :

But in peer to peer network,there is no dominancy for anyone.here all the computer in the network themseif shares the prayority by interconnecting them sholder to sholder,this type of networks are usally done for LAN(local area network).
