What Internet uses for DATA Transmission?
Q. Does internet is using packets switching as default transmission technique?Is there any advanced option available to communicate data on INTERNET?
Internet is using packets switching as default transmission technique. Packet switching is used in the Internet and most local area networks. The internet is implemented by internet portocal suite using variety of link layer technologies.For ex: Ethernet,Frame Relay,etc. The advanced option available to communicate data on internet is INTERNET PROTOCOL.
INTERNET PROTOCOL(IP)
The Internet Protocol (IP) is defined as the protocol for sending data from one computer to another across the Internet, with each computer having at least one IP address that identifies it from all other computers on the Internet. This protocol is used with other protocols within the IP suite, most notable of which include:
Transmission Control Protocol (TCP) —
used for data transmission . TCP is a standard that defines how to establish and maintain a network conversation through which application programs can exchange data. TCP works with the Internet protocol(IP), which defines how computers send packets of data to each other.
User Datagram Protocol (UDP) —
used by programs to send short datagram messages UDP is a communications protocol that is primarily used for establishing low-latency and loss-tolerating connections between applications on the internet. It speeds up transmissions by enabling the transfer of data before an agreement is provided by the receiving party.
Internet Control Message Protocol (ICMP) —
messages used for diagnostic or error-generating purposes.The Internet Control Message Protocol (ICMP) is a network layer protocol used by network devices to diagnose network communication issues. ICMP is mainly used to determine whether or not data is reaching its intended destination in a timely manner.
Hypertext Transfer Protocol (HTTP) —
application protocol that uses hyperlinks between nodes containing text.HTTP is the protocol used to transfer data over the web. It ISpart of the Internet protocol suite and defines commands and services used for transmitting webpage data.
Post Office Protocol (POP) —
used by local email clients to retrieve email from a remote server over TCP IP. POP is a type of computer networking and Internet standard protocol that extracts and retrieves email from a remote mail server for access by the host machine. POP is an application layer protocol in the OSI model that provides end users the ability to fetch and receive email.
File Transfer Protocol (FTP) —
protocol to transfer computer files from a server to a client and vice versa. FTP is a standard Internet protocol for transmitting files between computers on the Internet over TCP/IP connections. FTP is a client-server protocol where a client will ask for a file, and a local or remote server will provide it.
Internet Message Access Protocol (IMAP) —
a communication protocol used by email clients to retrieve messages from a mail server over TCP IP.IMAP is a protocol for accessing email or bulletin board messages from a (possibly shared) mail server or service. IMAP allows a client e-mail program to access remote message stores as if they were local.
