What are the two protocols used in the transport layer?
TCP and UDP
Correct:
UDP (User Data-gram Protocol) is a communications protocol that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol.
UDP provides two services not provided by the IP layer. It provides port numbers to help distinguish different user requests and, optionally, a checksum capability to verify that the data arrived intact.
TCP (Transmission Control Protocol) is a set of rules (protocol) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet. (TCP/IP) is the know definition by most.

The secure socket layer protocol uses what port?
It depends on what SSL is being used for (HTTP, as in secure web pages; FTP; Telnet; etc.). Below is a non-exhaustive list of various port numbers used for protocols with SSL implemented: * HTTP: Port 443 * FTP (Data): Port 989 * FTP (Control): Port 990 * Telnet: Port 992 * IRC: Port 994 * pop3: Port 995 I hope this was the information you were looking for.
What is the purpose of the ipv4 address?
Identify the node in the network.
Every TCP/IP packet contains 2 IP addresses: the sender's IP and the destination IP. These are used for multiple purposes (e.g. routing, handshake protocol management).
Which Layer 4 protocol is used to transport voice packets in a VoIP deployment?
UDP - primarily for speed is used to transport voice packets in a VoIP deployment.
