Advantages- You have your own cable so data goes directly to the computer it also has a good speed due to direct cable
Disadvantages- Expensive as a lot of cables are needed. If the server breaks so does the network]]> 2017-02-03 13:46:58 UTC https://padlet.com/11jsmithurst/m530er10jpum/wish/151427261 11agilder https://padlet.com/11jsmithurst/m530er10jpum/wish/151427378 If 2 or more networks need to be connected we use a Bridge. This sends the data where it is needed]]> 2017-02-03 13:47:08 UTC https://padlet.com/11jsmithurst/m530er10jpum/wish/151427378 11agilder https://padlet.com/11jsmithurst/m530er10jpum/wish/151427602 A gateway is the same as a bridge HOWEVER it is used to connect 2 different networks together e.g. star and peer-to-peer]]> 2017-02-03 13:47:43 UTC https://padlet.com/11jsmithurst/m530er10jpum/wish/151427602 11jsmithurst https://padlet.com/11jsmithurst/m530er10jpum/wish/151429645 We will use a server rather than a client setup as a server is more powerful]]> 2017-02-03 13:53:42 UTC https://padlet.com/11jsmithurst/m530er10jpum/wish/151429645 11jsmithurst https://padlet.com/11jsmithurst/m530er10jpum/wish/151431430 WWW (World wide web)- access to files
Extranet- everyone accesses outside
Intranet- network everyone accesses
Internet- e.g. routers, switches]]> 2017-02-03 13:58:57 UTC https://padlet.com/11jsmithurst/m530er10jpum/wish/151431430 11agilder https://padlet.com/11jsmithurst/m530er10jpum/wish/151431443 This is how data is physically sent across a network. The 3 main types are:
Network Cable-  Made of Copper and covered in plastic for protection, it is very cheap however the longer it is the more degraded. Network cables are also expensive to install but has a faster speed compared to WiFi.
Fibre Optic Cable- This is very expensive to buy and install although it is very fast, secure and does not degrade over long periods of time.
WiFi- WiFi is cheap to install BUT is slow in comparison to cable, the signal strength can be weak behind walls and can be lost.

Data Transmission- Data can be transmitted by:
Frame Relay -
DSL (Broadband)
Cable]]> 2017-02-03 13:58:59 UTC https://padlet.com/11jsmithurst/m530er10jpum/wish/151431443 11jsmithurst https://padlet.com/11jsmithurst/m530er10jpum/wish/151433345 VLE will be included 
benefits:
Where you go on the internet to learn saving resources and making it available 24/7 
Greater parental involvement 
Pupils can keep up if they're 
are off sick]]> 2017-02-03 14:04:17 UTC https://padlet.com/11jsmithurst/m530er10jpum/wish/151433345 11agilder https://padlet.com/11jsmithurst/m530er10jpum/wish/151437003 De Jure- This is the LAW meaning if you buy a DVD you know it will wonk in any DVD player as the standard is set by the law.
De Facto- This is not set by the law but it is usually the 'normal' thing to use e.g. it is not the law to have windows on computers but people use it anyway.]]> 2017-02-03 14:15:20 UTC https://padlet.com/11jsmithurst/m530er10jpum/wish/151437003 11agilder https://padlet.com/11jsmithurst/m530er10jpum/wish/151437254 TCP/IP - data transfer in packets
