1. Explain Which version of IP is discussed in this document?

IP version 4 (IPv4) is discussed in this document.

2. Explain How higher-level data is carried by IP to a destination host?

The data from higher-level protocols like TCP, UDP is encapsulated in an IP datagram and transmitted to the destination host. IP will not modify the higher-level data.

3. Tell me Is there a limitation on the minimum size of a IP datagram a network can handle?

Yes. All IP networks must be able to handle datagrams of at least 576 bytes in length.

4. Explain What do you mean by IP is a connection-less protocol?

IP is a connection-less protocol because it does not maintain state information about the connection to a destination host. Each datagram is handled independent of other datagrams and also each datagram may reach the destination through different network routes.

5. Explain What is IMAP Protocol?

IMAP (Internet Message Access Protocol) Is a standard protocol for accessing e-mail from your local server. IMAP is a client/server protocol in which e-mail is received and held for you by your Internet server. As this requires only a small data transfer this works well even over a slow connection such as a modem. Only if you request to read a specific email message will it be downloaded from the server. You can also create and manipulate folders or mailboxes on the server, delete messages etc.

6. Explain What is the role of IP in the TCP/IP protocol suite?

IP is used for

1. Transmitting data from higher-level protocols like TCP, UDP in IP datagrams, from one host to another host in the network.
2. Identifying individual hosts in a network using an IP address.
3. Routing datagrams through gateways and
4. Fragmenting and reassembling datagrams based on the MTU of the underlying network.

7. Please explain IMAP?

IMAP: Internet Mail Access Protocol..
It is used for incoming mail in client/remote users of a mail server. A user do not download e- mail in her pc from server.just to read or access from server. email saves in a server...

8. Explain Which RFC discusses IP?

RFC 791 discusses about the IP protocol version 4.

9. What is an IP Datagram?

An IP datagram is a basic unit of information used by the IP layer to exchange data between two hosts. A IP datagram consists of an IP header and data.

10. What is IMAP4?

Legacy Interactive Mail Access Protocol (IMAP) access to Exchange is also available, which can enable an Exchange server to be accessed via IMAP applications, such as some UNIX mail clients. As with the POP3 protocol, IMAP support must be explicitly turned on.
