Denial of Service attack AKA DDoS This is where an attacker makes multiple connection attempts to a service (not just the webservice) on a netowrk machine. The connection attempt is made however the attackers program does not reply to the ACK response from the server. This causes the process of the TCPIP disconnect to start after 9 TCP retries the connection is terminated. The problem with this is that there is a time delay between the connection SYNC-ronise frame and the Disconnect frame which hangs a socket for that time. Since the server will have a maximum number of Sockets available at any one time multiple connection requests like this fill them up effectively clogging the server. Back a few years on a badly written TCPIP stacks the system used to keep generating sockets until it ran out of memory and/or the server faulted and crashed. Since the server cannot tell a legitamate connection from a fake one it treats them the same therefore this attack type is not preventable.
