Join Greg Sowell for an in-depth discussion in this video Connection vs. connectionless, part of Networking Foundations: Protocols and CLI Tools.
- TCP and UPD utilize the two connection types.…Connection oriented and connection-less.…TCP is considered connection oriented.…This means it uses a system to provide…reliable delivery of traffic.…TCP utilizes a system known as the three way…handshake to establish connections.…Before a connection is considered established…both hosts need to send and receive a send packet,…and an ACK packet.…Technically this could be four separate messages,…but one of these transmissions can include…both a send and an ACK,…thus we have a three way handshake.…
The client host will initiate the interaction…to the server by sending a send packet.…The client then waits for a response.…The server responds to the client…by sending a send ACK packet.…The client then completes the handshake…by returning an ACK.…The ACK packet is part of the positive…acknowledgement system of TCP.…Once enough information is sent…TCP will wait for an ACK or acknowledgement.…The amount of information that can be sent…before a response is necessary…is known as the Window size.…
Protocols are the lifeblood of modern communication. By the end of this course, you'll know what you need to troubleshoot any network connection and keep the communication flowing.
Note: This course maps to domain 3 of the MTA Networking Fundamentals exam.
- Identify reasons why connectionless transmissions are faster.
- Determine what type of attack a gratuitous ARP announcing itself as a legitimate host indicates.
- State what IGMP snooping is useful for.
- Describe the best approach to use FTP to view and rename files on a server when your client is behind a firewall.
- Assess whether SSH is natively supported on Windows or not.
- List good uses for the arp command.
