The SYN packet, the SYN ACK packet , And ACK packet
Packets relate to the sending and receiving of batches of data between two devices.
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. For example, when an HTML file is sent to you from a Web server, the Transmission Control Protocol (TCP) program layer in that server divides the file into one or more packets, numbers the packets, and then forwards them individually to the IP program layer. Although each packet has the same destination IP address, it may get routed differently through the network. At the other end (the client program in your computer), TCP reassembles the individual packets and waits until they have arrived to forward them to you as a single file. TCP is known as a connection-oriented protocol, which means that a connection is established and maintained until such time as the message or messages to be exchanged by the application programs at each end have been exchanged. TCP is responsible for ensuring that a message is divided into the packets that IP manages and for reassembling the packets back into the complete message at the other end. In the Open Systems Interconnection (OSI) communication model, TCP is in layer 4, the Transport Layer. *This answer was taken from http://searchnetworking.techtarget.com/definition/TCP
datagram is used in conectionless n/w e.g. UDP Whereas packets used in connection oriented n/w e.g. ATM X.25 tcp
A ping command is to checks whether the client can send or receive packets . A Ping Flood can be defined as an attempt by an attacker on a high bandwidth connection . It is to saturate a network with packets in order to slow the traffic .
salam http 1.0 establishes a TCP connection for each packet http 1.1 uses only one connection for all packets
data packets
Data packets are the units of data that are exchanged between nodes on a network. A typical packet contains around 1,000 to 1,500 bytes.

You simply divide 64 by 4 and that gives you 16 free packets.

It's neither. IP is a transport layer protocol. Connection/Connectionless imply the network layer. Look up the OSI model. Actually you are correct, but it doesn't just go that far. The definition of connectionless is the ability to send and receive packets without already establishing connectivity between two or more specific entities. IPv4 is connectionless, meaning if I send information via IPv4 I can just send the packets without having to do much more than click "return". Hope this helps.

TCP- Transfer control protocol. it control the transprotaion of the data. its established the connection between the hosts. its work on 4th layer. IP -IP mean internet protocol.its deal with the packets
IP is connectionless because you don't want routing to reply to every routing request; it would slow things down to almost a stop. The router has to assume that the packet arrives where it was sent.
The firewall that only allows packets of registered connection is called packet filter. It is also the central piece in firewalling.
