In order to begin the handshake process, the client sends a SYN packet to the server. This is required to establish a synchronization with the server in order to ensure that both the client and the server will maintain and keep their exchange of packets in the right order. In order to complete the "handshake," the reponse from the server will be an ACK packet.

What is a 1-bit flag in the TCP header used to indicate the initial value of the sequence number?
The SYN flag is a 1-bit flag in the TCP header used to indicate the initial value of the sequence number. It is only set in the first two segments of the three-way TCP connection establishment sequence.
How many other tcp datagrams contained a SYN bit?

What is padding in tcp segment?
The internet header padding is used to ensure that the internet ends on a 32 bit boundary. The padding is zero.
How many bits does the DSCP use in the IP header?
how many bit header Ip v4
What is a TCP Handshake?
A TCP Handshake happens whenever a TCP connection is used. A TCP Handshake provides a small bit of security and is used to increase the reliability of IP communication. If the server is unavailable, too busy, or the connection between the client and the server is not reliable, the handshake will fail. The handshake will also fail if the requested port is blocked by a firewall or other filtering device.For example, when your computer visits wiki.answers.com, it does a TCP Handshake on the standard HTTP port, port 80, data is transfered, then the connection is closed.The client connects on port 80 with a SYN (Synchronize) and (if all goes well) the server replies with an ACK (Acknowledge) and another SYN (Synchronize). The client will reply with a final ACK (Acknowledge), completing the handshake.A client and server going through a TCP Handshake looks like this:Client: SYNServer: ACK/SYNClient: ACKOr to put it simply, if you asked your computer to visit wiki.answers.com (port 80), the handshake would look like this:Your Computer: Hi, wiki.answers.com! Can we talk on port 80? (SYN)Answers.com: Hi! Sure! (ACK) Are you ready? (SYN)Your Computer: Yep! (ACK)The above connection is known as a 3-Way Handshake.Once the TCP Handshake is complete, the client and server exchange data (with an ACK after every packet sent, to confirm that the packet safely reached it's destination with the correct checksum). Once the client and server are done, the handshake is finished and is closed.Once the connection is made, the server can still actively deny the connection. The server can choose to not reply to the first SYN from the client (which will make the server appear offline) or it can complete the TCP Handshake, then deny the connection (commonly known as an "active refusal").If you'd like to explore more about network packets, try downloading Wireshark, an open source packet capture utility.

The current version of TCP IP IPv4 uses a what bit addressing scheme?
Thirty Two bits in four eight bit octets.
Contrast the IPv4 and the IPv6 header fields?
Simplified header format. IPv6 has a fixed length header, which does not include most of the options an IPv4 header can include. Even though the IPv6 header contains two 128 bit addresses (source and destination IP address) the whole header has a fixed length of 40 bytes only. This allows for faster processing. Options are dealt with in extension headers, which are only inserted after the IPv6 header if needed. So for instance if a packet needs to be fragmented, the fragmentation header is inserted after the IPv6 header. The basic set of extension headers is defined in RFC 2460.
What is the root word of synchronize?
The suffix of synchronize is -ize. The suffix is the bit at the end of the word.
