How does an email go through the OSI model?

The simplest example of communication flow through the OSI Model is an email application. When a sender clicks “Send” on an email application, the message is sent to the presentation layer using a defined protocol (SMTP for outgoing email).

Which OSI layer is responsible for email and file transfers?

application layer
The application layer concerns the networking processes at the application level. This layer interacts directly with end-users to provide support for email, network data sharing, file transfers, and directory services, among other distributed information services.

How do messages travel through network layers?

In more complex communication, messages are delivered through several intermediate communication entities called routers. At each router, a message is passed up through some of the layers and then back down on the way to a different router or a destination machine.

What layer does email use?

Email runs on SMTP(Simple mail transfer protocol) which is application level protocol. So,Email belongs to application layer of OSI Model.

What are the different ways to access email?

Three ways to access your email

1. Using your favorite mail program such as Outlook, Thunderbird or Apple Mail.
2. Using your smart device or phone such as Blackberry, Droid, iPhone, iPad, iPod, Palm and all other smart devices.

How does a message is sent from one network to another?

Each of these messages can be sent across a data or information network by first converting them into binary digits, or bits. These bits are then encoded into a signal that can be transmitted over the appropriate medium. In computer networks, the media is usually a type of cable, or a wireless transmission.

How data travels from one computer to another using the OSI model?

Data travels from the sending computer down through all the layers to the physical layer where the data is put onto the network cabling, and then sent to the physical layer of the receiving computer where the process reverses and the data travels up through the layers to the application layer of the receiving computer.
