Transcription

1 Data Transmission Transmission: the process of passing something from one person or place to another of passing something from one person or place to another

2 Data Transmission Main types of Transmission Dual use of Voice and Data Wireless communication methods Connections to the Internet Hardware required for a wireless network

3 Types of Transmission Unicast Data is sent to only one recipient Multicast Same data sent to a group of people Broadcast Data is sent to everyone who wishes to receive the data e.g. radio, television

4 Voice and Data Transmission Both Local Area Networks and Wide Area Network cables or Wireless links can be used to transfer computer data and voice messages at the same time. This can save a company money as it only need one set of cables for an internal phone system or can use the Internet for Phone calls An example of this is VOIP or Voice over Internet Protocol

5 LAN Voice and Data The cables on a LAN can also be used to provide a internal telephone network Saves money and disruption as only 1 set of cables has to be installed

6 WAN Voice and Data WAN computers use the public telephone lines to transfer data Can be set up to carry either: Voice OR data signal (standard dial up) or Voice AND data (Broadband, ADSL, ISDN) The cables that form the backbone of the Internet are complex enough that they can carry Data, Voice and Video at the same time.

7 Wireless Communications Transmission of data around a network WITHOUT cables Easier to change the network layout as there are NO cables to install More flexible work place User not tied to a single location

8 Types of wireless networking WPAN - Wireless Personal Area Network network operates over a small area e.g. between a laptop, portable printer and PDA ( Bluetooth networks <30m) Usually one or two users at most at anyone time WLAN Wireless Local Area Network Multiple users Usually a single office or building Uses infrared or radiowaves WWAN Wireless Wide Area Network Operates over a very wide area Often need line of site Usually uses microwaves to connect to or more LANs

9 Hardware for Wireless wnic wireless network interface card Networking Transmitter/Receiver attached to the server computer

10 Connecting to the Internet Different ways of connecting: Dial-up modem ADSL ISDN Cable modem Leased line

11 Dial up Requires a MODEM (MODulator/DEModulator) A piece of hardware to transfer the computer signal to the telephone network and vice versa. Digital computer signal is converted to an analogue signal for transfer on the telephone lines. Slowest way of connecting to the Internet Only pay for the time connected

12 ADSL Asynchronous Digital Subscriber Line Uses a telephone line and an ADSL modem Telephone line can be used at the same time as data transfer Some areas do not have ADSL coverage Commonly known as BROADBAND high speed of data transfer is possible ( typically 2 Megabits of data per second)

13 ISDN Integrated Services Digital Network Voice and Data can be sent on the same telephone line Different speeds are available Faster than dialup but not usually as fast as Broadband

14 Cable Modem Uses Cable television cables to transfer data Requires a Cable MODEM Transfer rates are usually as high as ADSL Only available where cable TV is available

15 Leased Line A dedicated telephone line which is rented by an organisation Permanent data connection between two locations Data can be kept very secure Fixed monthly fee Usually expensive

16 Broadband Broadband is a general term that is used to describe an Internet connection that is faster than Dialup Most commonly used for ADSL or CABLE Modem connections Always on

17 Advantages and disadvantages Connection Type Dialup Modem ADSL Advantage Inexpensive Wide availability Affordable Shares telephone line Wide variety of speeds and prices Choice of providers Disadvantage Slow Connection not always on Using modem ties up the phone line Limited availability Speed can vary

18 Connection Type ISDN Cable Modem Advantage Does not tie up phone line Usually faster than 56k Relatively inexpensive Disadvantage Can be difficult to set up Not practical for more than 10 computers Limited availability In UK Sharing with neighbours poses a security risk Usually for home users

19 Connection Type Leased line Advantage Very fast High level of security High bandwidth Disadvantage Aimed at high use business users Very expensive

20 Costs and speeds Connection Type Dial up Modem ADSL ISDN Cable Modem Leased Line Costs 1p per minute pcm 20 pcm 25 pcm Speed Up to 56Kbs 2Mbs (currently 10 Mbs available in UK) 2Mbs 2Mbs (currently 10 Mbs available in UK)
