What is a port? Write about any two types of ports?

In computer networking, a port is a communication endpoint. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service. A port is identified for each transport protocol and address combination by a 16-bit unsigned number, known as the port number. The most common transport protocols that use port numbers are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).

A port number is always associated with an IP address of a host and the type of transport protocol used for communication. It completes the destination or origination network address of a message. Specific port numbers are reserved to identify specific services so that an arriving packet can be easily forwarded to a running application. For this purpose, port numbers lower than 1024 identify the historically most commonly used services and are called the well-known port numbers. Higher-numbered ports are available for general use by applications and are known as ephemeral ports.Ports provide a multiplexing service for multiple services or multiple communication sessions at one network address. In the client–server model of application architecture, multiple simultaneous communication sessions may be initiated for the same service.

Two types of port are :-

Serial Port

Parallel Port

Write the advantages of Email?

1) Email is a free tool. Once you are online, there is no further expense that you need to spend on in order to send and receive messages.

2) Email is quick. Once you have finished composing a message, sending it is as simple as clicking a button. Email, especially if an email system is integrated into the network, is sent, delivered and read almost immediately.

3) Email is simple. It is easy to use. Once your account is set up, composing, sending and receiving messages is simple. Also, email allows for the easy and quick access of information and contacts.

4) Email allows for easy referencing. Messages that have been sent and received can stored, and searched through safely and easily. It is a lot easier to go through old email messages rather than old notes written on paper.

5) Email is accessible from anywhere – as long as you have an internet connection. Whether or not you are in the office or on the field, or even overseas, you can access your inbox and go through your messages.

6) Email is paperless, and therefore, beneficial for the planet. Not only can you reduce the costs of paper, you are actually reducing the damage paper usage does to the environment.

7) Email allows for mass sending of messages. An effective medium to utilize to get your message out there, you can send one particular message to several recipients all at once.
