I enjoyed the three older films but the new one was so cheesy and soun-Star Wars that it didn't seem to fit in with the others. I mean, it was socommercial and so inane.

Be prepared to defend your choice.1234a household with a young familya small home-based businesssomeone who enjoys online gamingsomeone who doesn't want a lot of spam in their emailUsing a free ISP requires no new technology - allyou need is a computer, a modem, a telephone line,and the appropriate software (which is availablefree of charge when you sign up with the service).Once installed on your PC you can access theInternet as normal, but your connection costs onlythe price of a local call, and you pay nothing else not even for features such as an unlimited numberof email addresses, unlimited Web space andoriginal content.Most of the services are very similar, but it isstill worth looking around for a service that offersat least the following features:CD-ROM or Online sign upMany free ISPs require you to sign up for theirservice online (which obviously means you alreadyneed to have an Internet connection and someexperience with setting up a dial-up networkingconnection).
If you are a complete beginner, you'llneed a free ISP which can provide its sign-upsoftware on CD-ROM that will automaticallyconfigure your computer to access the Internet.Local rate callsAlthough using the ISP is free, you still have to payfor your online time. Nearly all ISPs howeverprovide local call access numbers. Any free ISP thatuses a national rate number or charges an initial setup or administration fee should be avoided.EmailHaving several email accounts is very useful - youcan separate business and personal email forexample, or provide an address for each member ofyour family. Many free ISPs also offer only Webbased mail which is great if you need to get intoyour computer on the move as you can access itfrom any computer with Internet access.
POP3 emailhowever is faster and more efficient and can bedownloaded to your PC to read offline - acombination of the two is ideal.Free Web spaceA decent amount of free Web space would bearound 25-50Mb. This would be sufficient for mostof your own personal website developments. Alsocheck to see if there are any restrictions on your useof Web space, since some free ISPs will not let youuse the space for commercial purposes.NewsgroupsNewsgroups are huge discussion forums on theInternet that are an amazingly rich resource ofinformation and a brilliant way to communicatewith other Internet users. Unfortunately they arealso the home to some of the most unsavourycontent on the Internet (they are largelyunmoderated) and as a result many free ISPs restrictaccess to some or all newsgroups.Customer SupportCheck support line charges; many free ISPs use theirsupport lines as a source of revenue relying on yourignorance to make money from the call.The target audience is generally Net novices and,as a result, support lines are pretty much jammed allday with queries and connection problems.Most use premium rate telephone line charges.However, there are a few free ISPs who only chargelocal or national rates for their telephone helplines.Reliable ServiceOf course all the features in the world won't make ascrap of difference if the ISP is unreliable and youfind it impossible to log on.
Look out forrecommendations from friends and shop around.Interestingly many of the more popular serviceshave become saturated and seem to be in a constant'upgrading the network' phase.There is nothing to stop you having more thanone free ISP account. Windows will even enable youto run a number of different free ISP connection setups on the same PC so you can easily have multipleaccounts and just use the best one on the day.UNIT 12 The Internet 85Option AOption COption BBigwigArsenal7 POP3 email accounts eachwith up to 1, 000 aliasesScans all emails for virusesbefore they reach you15Mb free Web spaceConnectFreeAccess to most newsgroups• 5 POP3 email addresses eachpassword-protected5Mb free Web space• Full access to newsgroupsTechnical support at50p/minute• Unlimited Web space5 POP3 email accountsAccess to 25, 000 newsgroups• Free online webpage designserviceTechnical support at50p/minute• Free access to online multiplayer gamesComprehensive onlineinformation and easy -to-followhelp availableOption DOption EFree4allUnlimited email addressesUnlimited POP3 email accounts25Mb Web spaceEmail virus protection and junk email filtersOnline help section25Mb of free Web space with option to increaseat £1 per Mb per monthFree access to CyberPatrol for blocking orrestricting access to inappropriate content onthe WebPowerful enough to create quite advanced,functional sitesTechnical support at local call ratesFor further details of ISPs try:www.

This 32-bit coding system assigns anumber to every node on the network. There arevarious types of addresses designed for networksof different sizes, but you can write every addresswith a series of numbers that identify the majornetwork and the sub-networks to which a node isattached. Besides identifying a node, the addressprovides a path that gateways can use to routeinformation from one machine to another.Although data-delivery systems like Ethernet orX. 25 bring their packets to any machineelectrically attached to the cable, the IP modulesApplicationprogramsDatabase and otherapplicationsaddress Net-BIOSTerminal-emulatorprograms addressFTPCommercial emailprograms addressSMTPNet-BIOS programInterfaces thataddress TCPNet-BIOSFTPFile TransferProtocol softwareaddresses TCPSMTPSimple MailTransfer Protocolsoftware addressesTCPSoftware thatperformstransmission-controldelivery andrecovery functionsTCP layersIP layersSoftware thatrecognises Internetaddresses and UDProutingNetwork adaptor orserial-port driversoftwareDriver code uniqueto the hardwareNetwork adaptor orserial-portTo networkRS-232C to X.
