36 Firewalls Software and hardware that filters and secures your private network, allowing only authorized access and transmissions of your internal data.

37 Computer Viruses Malicious computer programs: Virus Unauthorized set of programmed code that attaches itself to other programs. Worm Independent programs that may replicate itself throughout the network. Trojan Horse Masquerades as a legitimate program but has malicious software inside Are computer bugs a virus??

38 Poll HFTP

39 TCP/IP TCP/IP Transmission Control Protocol/Internet Protocol Is NOT a telecommunication communications protocol. TCP Packets: Are numbered so they can be reassembled in the correct sequence at the destination. Are transmitted over the network as capacity becomes available. Forwarded across the network separately and do not necessarily follow the same route. Do not contain destination addresses only. Header information includes Total length of the packet, destination IP address, Source IP address, and Error checking information. DOES NOT include sender s login information.

40 Packet Switching TCP/IP Checking for valid packets, destination address, best route, assembling packets in order, but NOT for data compression. Static verses Dynamic Addresses DHCP: Dynamic Host Configuration Protocol is used to assign dynamic IP addresses on an as-requested basis. 3 Classes of IP Addresses

41 Class A IP Address Classes ###. xxx.xxx. xxx (ex. 26.x.x.x) (1-126).(1-254).(1-254).(1-254) Class B HFTP ###.###.xxx.xxx (ex x.x) ( ).(1-254).(1-254).(1-254) Class C ###.###.###.xxx (ex x) ( ).(1-254).(1-254).(1-254) IP Classes

42 Parallel Transmission Multiple channels to transmit several bits of data at a time Timed pulses sent on other wires within the same cable to coordinate the flow of data Parallel ports, parallel cable, user configuration of controller Over short distances -LAN

43 Serial Transmission HFTP Single channel to transmit bit by bit Bits travel as a sequence over a single wire with start and stop bits to coordinate data flow Serial cable, serial ports, user configuration of controller Long distances - telephone transmission

44 Modems Converts on and off digital pulses of computer data into on-and-off analog tones that can be transmitted over a normal telephone circuit. Uses: Allow computers to communicate over distances , internet, bulletin boards Polling, file transfer, system support
