Network Protocol
  • A set of rules that has been established to
    specify the way in which data need to be
    transmitted between various devices in a network,
    is referred to as a network protocol. It lets
    devices that are connected with each other
    communicate, despite the differences that exist
    in their structure, internal processes or design.
    Network protocols play an important part in
    digital communications.
  • Various devices can interact with each other due
    to network protocols that ensure that
    predetermined rules exist in the software and
    hardware of these devices. In the absence of
    network protocols, neither a WAN (Wide Area
    Network) nor a LAN (Local Area Network) can
    function properly.
  • The various types of network protocols will be
    mentioned in the following slides.

4
TCP (Transmission Control Protocol)
  • TCP is the abbreviation for Transmission Control
    Protocol. It is a very popular communication
    protocol that is meant for communicating over a
    network. Any message is divided by it into series
    of packets, which get sent from a source to the
    destination. At the destination these get
    reassembled.

  • Whoa! Thats a big number, arent you
    proud?

6
IP (Internet Protocol)
  • IP is the abbreviation for Internet Protocol. It
    is used as an addressing protocol. It is usually
    used along with the Transmission Control
    Protocol. TCP/IP is one of the most popular
    protocols for connecting networks.
  • The IP refers to a set of rules that exists for
    routing packets of data as well as for addressing
    them. This enables them to be transmitted across
    networks and ensures that they reach the correct
    destination. IP information is present in each
    data packet, which helps routers to send these
    data packets to their destination.
  • Every website on the Internet has an IP address.
    These websites are made accessible by web hosting
    companies through the service of web hosting. The
    most efficient web hosting services globally are
    usually referred to as the Best Windows Shared
    Hosting, the Best Linux Dedicated Hosting the
    Top Cloud Hosting etc.

7
UDP (User Datagram Protocol)
  • UDP is the abbreviation for User Datagram
    Protocol, and it is a core component of the
    Internet Protocol suite. UDP enables applications
    to send messages, which are referred to as
    datagrams, to the hosts on an IP network. A User
    Datagram Protocol uses a connectionless
    communication model that has a minimum amount of
    protocol mechanisms. A UDP aids in creating such
    links between various applications, which are
    loss-tolerant and have low latency.

8
FTP (File Transfer Protocol
  • FTP is the abbreviation for File Transfer
    Protocol, and it serves as a standard
    communication protocol for transferring files
    from a server to a client, over a network. It is
    built on the architecture of a client-server
    model.

9
POP (Post Office Protocol)
  • POP is the abbreviation for Post Office Protocol.
    It is an application-layer Internet standard
    protocol. E-mail clients use it for retrieving
    e-mails from a mail server. POP3 i.e. POP version
    3 is used most commonly.

10
SMTP (Simple Mail Transfer Protocol)
  • SMTP is the abbreviation for Simple Mail Transfer
    Protocol. It is an Internet standard
    communication protocol for the transmission of
    electronic mail. SMTP is used by mail servers and
    by other message transfer agents for sending and
    receiving mail messages.

11
HTTP (Hypertext Transfer Protocol)
  • HTTP is the abbreviation for Hypertext Transfer
    Protocol. It is used for transferring a hypertext
    between two systems or among multiple systems. It
    is an application layer protocol that is meant
    for collaborative, distributed information
    systems of hypermedia. HTTP acts as a
    request-response protocol in the client-server
    model.

12
HTTPS (Hypertext Transfer Protocol Secure)
  • HTTPS is the abbreviation for Hypertext Transfer
    Protocol Secure, and it is an extension of HTTP
    (Hypertext Transfer Protocol). It is used
    extensively on the Internet, and is meant to
    ensure secure communication over a computer
    network. The communication protocol in it is
    encrypted with the aid of TLS (Transport Layer
    Security). Hence, it is also referred to as HTTP
    over TLS.

13
Telnet
  • Telnet refers to an application protocol, which
    is used on the Internet or in LAN (Local Area
    Network). A bidirectional, interactive
    communication facility that is text-oriented is
    provided by it with the aid of a virtual terminal
    connection.

14
Gopher
  • Gopher is a communication protocol that is meant
    for searching and distributing, as well as for
    retrieving documents in IP networks.
