- 48give 2 advantages of wireless internet connectioncan be used wherever there is a connected wireless hub, not fixed to a stationary computer

- 50give an advantage of broadband connection to the internetusually faster and better quality
- 51give a disadvantage of broadband connection to the internetrequires a hard wired connection so don't have the flexibility of movement offered by wireless connection.
- 52describe the characteristics of broadband internet connectiona computer is cabled from its network card directly to the ISP via a digital network based on fibre optics

- 64how do search engines work?search engines create vast databases of websites by retrieving information from the html, the search engine searches that database for the keyword you type in and returns a list of site in order of relevance
- 65PoP Point of PresenceAn access point to the internet. Normally, it is a location which contains all of the hardware
which allows internet users access to the internet. An Internet Service Provider (ISP) may
operate several PoPs in their area to allow good access to the internet. - 66NAP network Access PointAn interchange between networks within the internet. It allows ISPs to interconnect with each other
- 67IP internet ProtocolThe protocol used to route packets of information across the internet.
An individual unit of data which is carried across a network, including the internet. It is made
up of a header which identifi es the packet and a body which is the actual data message. It
is one of the functions of the Transmission Control Protocol (TCP) to organise an internet
message into packets. - 68ServerA computer or program which runs purely to serve the needs of other computers. It runs special server software to service the requirements of the users (clients). There are several types of servers, including file servers and printer servers on a local network area (LAN), and web and email servers that manage communication with the internet
- 69ClientA computer which uses the services provided by the server
- 70RouterA piece of hardware that connects two or more networks. In relation to the internet, data from
the ISP is sent into the network and the router then directs the data packets to the correct
destinations. The router also handles data travelling in the other direction. Routers can be
described as ‘directors of traffic’ for the networks. - 71Connecting backboneThe main connecting data routes between large networks on the internet and smaller networks in local regions
- 72TCP Transmission Control ProtocolThe protocol which takes data from a user’s application program and passes it to the IP for
transfer across the internet. The reverse operation is performed at the destination computer,
i.e. the TCP reassembles the data (from individual packets) and forwards them to the user’s
application program. The close relation with the IP means that the terms are usually used in
combination, i.e. TCP/IP. - 73FTP File Transfer ProtocolA standard protocol which allows files to be transferred between two computers on a TCP-based
network. It is commonly used to download programs to your computer from other servers and to
upload web pages that you have created to the server that is hosting them on the internet. - 74ISP Internet Service ProviderDirect connection to the internet would be very costly and so ISPs provide a cost-effective
gateway for people and organisations to get onto the internet. In the UK there are many
ISPs, with some of the most popular ones being BT (British Telecom), Virgin Media and Sky. - 75iSP servicesIn addition to providing a gateway to the internet, ISPs normally provide additional services
such as email. Many also provide web space for the development of websites, technical
support and troubleshooting - 76WirelessUsed by wireless-enabled
devices (computers, mobiles,
smartphones, etc.) to log in to
the internet. Wireless is exactly
what it says; there are no wires to
connect. Not fixed to a
stationary computer.
Can be used wherever
there is a wireless hub
which is accessible. Need to have access to a wireless hub.
Can be less secure than wired
connections.
Tend to have slower data transmission
speeds than wired broadband methods. - 77BroadbandA wired connection to a
broadband supplier. Normally the
connection is via a network card
in the computer. Cable users have
an ethernet connection from
their computer to the network. Broadband
connections can give
better reception and
are usually faster than
dial-up. Requires a base which is wired in, so it
is less flexible than wireless. - 78Dial-upA wired connection via a
conventional telephone line,
which needs a modem to convert signals to and from analogue from transmissions. Can use existing
telephone circuits,
which is useful in some areas. Older technology gives poor reception
at times.
The conversion from digital to
analogue signals can cause errors.
Tends to be slower than other
connection methods. - 79What is a URL?Uniform Resource Locator
- 80SMTP Simple Mail Transfer ProtocolThe internet standard used for sending messages across IP networks in server-to-server transfers. Also used by email users to send a message to an email server
- 81POP3 Post Office Protocol 3Used to retrieve emails from an email server over a TCP/IP connection. This is the most widely used email retrieval protocol. Normally uses download emails to their local computer using POP3, deleting them from the email server
- 82IMAP Internet Message Access ProtocolThis is the other popular email retrieval protocol. Normally users work on the emails as they reside on the email server using IMAP and do not download them
- 83List five possible different kinds of threat to dataopportunist threats, computer viruses, other malware, phishing, accidental damage.
- 84describe an 'opportunist' threat to dataif someone finds a computer that has been left logged on, and then views, changes, or deletes data on the system.
- 85what is a 'computer virus'a virus is a small program that is able to replicate (copy) itself and thus spread like a disease
- 86what do viruses do?they generally alter or delete data, or change something in a computer system.
- 87how do viruses arrive on computers?they are generally attached to files or email messages.
- 88give some examples of other types of malwareworms, Trojan horses, adware, spyware,
- 89in malware terms what is a 'worm'A special type of virus that doesn't need to be attached to a file.
- 90in malware terms what is 'adware?'adware monitors the websites you visit and targets you for spam advertising
- 91in malware terms what is 'spyware'?spyware is like adware in that is tracks your internet activity and then passes your browsing habits on to a third party.
- 92in malware terms what is phishing?
