on, used to on duty or off duty or refueling for person who hasn’t card. Management card Hold by station owner, management card is used for station management. Pump-verifying card Hold by station master or manager, it is used to verify pump in troubleshooting. Maintenance card Hold by station or superior firm, it is used as maintenance of fuel dispenser. Parameter card The card is used as presetting parameters such as density, volume of pre-close valve. PSAM card PSAM card is employed to verify the validities of above cards, which is installed in reader of fuel dispenser. Fuel dispenser doesn’t work without RSAM card. There are many card seats for using on fuel dispenser. Card-cont fuel dispenser rolled fuel dispenser Card –controlled fuel dispenser actually is the one mounted an IC card reader. At present, most of card-fuel dispenser integrated keyboard and card reader, realizing the combination of balance with IC card. 5.1 St fuel dispenser ructure of IC card reader for fuel dispenser Diagram 3-26: Basic structure of IC card reader fuel dispenser In above diagram, CPU, adopted 32K byte memory, is core component in reader, which controlled all functions of reader. Port I is used for communicating fuel dispenser and realizing control manipulation such as readout filing data from fuel dispenser, download unit price and transmit operating information to fuel dispenser through keyboard. Port II is responsible for exchanging filled data with station’s supervision computer and transmitting filing record to background; readout important information from supervision computer such as black and white list, unit price and enquire blacklist and greylist. Memory is used to store filling record, blacklist and whitelist. Clock circuit provides the time in which filing record is generated. Matrix liquid crystal screen displays data prompting user and balance of card. PSAM card group contains PSAM card that is used for safety attestation and data encryption. User socket is used to insert IC card; card lock is insta

uch reliable communication.　　TCP requires that a connection must be opened before data can be send. The server application must perform a so-　　called passive open to create a connection with a known port number where rather than making a call to the　　network the server listens and waits for incoming requests.　　The client application must perform an active open by sending a synchronize sequence number (SYN) to the server　　application to identify the connection. The client application uses the server port number to send the SYN to the　　server. The server must send an acknowledgement (ACK) to the client together with the sequence number (SYN) of　　the server. The client in turn answers with an ACK an fuel dispenser d the connection is established. Now sending and receiving　　can start. After receiving a message an ACK messages is always returned.　　The TCP protocol is complex and time consuming because of the handshaking mechanism but this protoc fuel dispenser ol takes　　care of guaranteeing delivery of packets obviating the need to include that function fuel dispenser ality in the application protocol.　　Contrary to TCP UDP (User Datagram Protocol) is a very fast protocol as it specifies just the minimum mechanism　　required for data transfer. This has some disadvantages. Messages can be received in any order and a message　　send first could be received last. The delivery of UDP messages is not guaranteed at all and messages can be lost　　or even two copies of the same message might be received.　　UDP does not require a connection to be opened and data can be sent as soon as it is ready. UDP does not send　　acknowledgement messages so the data can be received or it can be lost. If reliable data transfer is needed over　　UDP it must be implemented in a higher-level protocol.　　UDP can be used with unicast communications if fast transfer is required such as multimedia delivery but the major　　advantage of UDP apply to broadcasts and multicasts.　　A.3 IP Addressing　　The IP (Inter

role but more people are now being indoctrinated by friends and families at home, and through internet chat rooms and websites. Radical “cyber-mosques�also exist. In a film shown by BBC s “Newsnight�on November 14th, Omar Bakri Mohammed, a Muslim cleric banned from Britain for inciting violence, was said to be preaching jihad online. Thomas Hegghammer of the Norwegian Defence Research Establishment, a think-tank, notes another trend terrorist groups are actively targeting European audiences. Speeches by al-Qaeda representatives posted on the web are now being given English subtitles—significant for British Muslims, who are less likely to speak Arabic than their continental brothers. The web is not fuel dispenser just for indoctrination and recruitment. Military tactics and bombmaking techniques are also available online. But the internet is no substitute for military training. For Britain s would-be terrorists, much of that takes place in Pakis fuel dispenser tan. Half of Britain s Muslims—about 800,000 people—are of Pakistani origin. Many travel to Pa fuel dispenser kistan often to visit family and friends or to do business. Almost all do so entirely innocently. Most of the would-be bombers of July 21st in fact had African ties—and only some of those charged with conspiring to blow up transatlantic flights in August had family connections in Pakistan. But three of the four suicide-bombers who attacked London on July 7th 2005 had roots in Pakistan and two had travelled there not long before. Before his arrest Dhiren Barot, sentenced last week to at least 40 years in jail for planning to kill thousands of people in attacks in Britain and America, was about to visit Pakistan to get money for the planned atrocities. He is also believed to have received military training there. Many of the 30 plots of which MI5 is aware have links to al-Qaeda in Pakistan, according to MI5. The Pakistani government seems unable to control the apparent growth in strength in areas bordering Afghanistan of both al-Qaeda and the Taliba
