Protocols:
These are set of Rules & Regulations that are
required for communications.
Port Number:
A port number is a way to identify a specific process to
which an Internet or other network message is to be forwarded when it arrives
at a server i.e. it is used to identify any service.
The Process/Application Layer Protocols:
TLS
(Transport Layer security):
1. Both
TLS and its forerunner, Secure Socket Layer (SSL), are cryptographic protocols
that come in really handy for enabling secure online data-transfer activities.
2. Activities
like browsing the web, instant messaging, internet faxing, and so on.
Telnet
(Terminal Emulation Network):
1. It is used to
remotely access the device in order to configure it.
2. It will
provide only command line not graphic mode.
3. Port no. = 23
4. Protocol used
= TCP (Transmission Control Protocol)
FTP
(File Transfer Protocol):
1. It
is used to Transfer files.
2. FTP
is not just a protocol, it is also a program. Operating as a protocol, FTP is
used by applications. As a program, it is employed by users to perform file
tasks by hand.
3. Port
no. = 20(For Data transfer) & 21 (For Authentication).
4. Protocol
used = TCP (Transmission Control Protocol)

3. Latest
version is POP3 i.e. version 3. POP4 is also available.
4. Port
no.= 110
5. Protocol
used = TCP (Transmission Control Protocol)
IMAP
(Internet Messaging Access Protocol):
1. It
is used to handle the Incoming mails i.e. used to receive mails.
2. It copy the data from server & paste into the user computer.
3. Latest
version is IMAP4
4. Port
no.= 143
5. Protocol
used = TCP (Transmission Control Protocol)
IMAP-S
(Internet Messaging Access Protocol Secure):
1. It
is used to handle the Incoming mails i.e. used to receive mails.
2. It copy the data from server & paste into the user computer.
3. Port
no.= 993
4. Protocol
used = TCP (Transmission Control Protocol)
SNMP
(Simple Network Management Protocol):
1. It
is used to measure Network performance.
2. Versions-
v1,v2,v3
3. Port
no.= 161
4. Protocol
used = for v3 =TCP (Transmission Control Protocol), for v1=UDP(User Datagram
Protocol)
5. Version
3 provide more security and message Integrity
(Correctness), authentication,
and encryption.
SSH
(Secure Shell):
1. SSH
protocol sets up a secure telnet session over a TCP/IP connection.
2. It
is a new generation protocol that is now used in place of rsh and rlogin- even Telnet.
3. Port
no.= 22
4. Protocol
used = TCP (Transmission Control Protocol)
HTTP
(Hypertext Transfer Protocol):
1. It
is used to upload and download the Web-Page i.e. it is used to manage
communications between web browsers and web servers and open the right source
when you click a link.
2. Port
no.= 80
3. Protocol
used = TCP (Transmission Control Protocol)
HTTPS
(Hypertext Transfer Protocol Secure):
1. It
is used to upload and download the Web-Page i.e. it is used to manage
communications between web browsers and web servers and open the right source
when you click a link.
2. It
uses SSL(Secure Socket Layer)
3. It
provide bunch of security tools.
4. Port
no.= 443
5. Protocol
used = TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
NET-
BIOS :
1. It
is used to resolve Host name into IP address (Work only with in the same
network).
2. By
default it is always enable.
3. Port
no.= 137
4. Protocol
used = TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
WINS
(Window Internet Name Server):
1. It
is used to resolve Host name into IP address (Work with in the different
network also).
2. Port
no.= 1512
3. Protocol
used = TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
DNS
(Domain Name Server):
1. It is used to resolve FQDN (Fully Qualified
Domain Name) into IP address and vice-versa.
2. Host
Name + Domain Name = FQDN
3. Port
no.= 53
4. Protocol
used = TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
DHCP
(Dynamic Host Configuration Protocol):
1. It is used to assigned IP address related
information automatically to the clients.
2. Port
no.= 67(For server) & 68(For client)
3. Protocol
used = UDP (User Datagram Protocol) for IPv4
4. If
we are assigning IPv6 addresses then Port no.= 546(for client) & 547 (for
server)
5. Protocol
used = TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) for
IPv6
