1.4 Internet Connections Flashcards
Copper cables (Wired connection)
Cheaper type of wired connection
Susceptible to electromagnetic interference
More likely to suffer from attenuation (network distortion)
Malleable (easier to bend) and less likely to break than other cables
Low bandwidth: struggles transmitting data all at once unlike fibre optic cables
Fibre optic cables (wired connection)
Very fast
Expensive
Signals transmitted as waves of light through a glass tube
Not effected by electromagnetic interference
Suffers less from attenuation
Higher bandwidth: can transfer more data at one time
Fibre optic cables are fragile
Bluetooth (Wireless connection)
Short range communication between devices (limit of distance is 10 metres)
Close proximity required (Con)
No additional hardware required (pro)
Microwave (Wireless connection)
Use radio waves to send signals across a large area via microwave towers
Transmit a large amount of data but antennas must be in LOS of each other with no obstructions
Affected by bad weather leading to higher chances of attenuation (Network distortion)
Satellite (Wireless connection)
Uses point to multipoint communication
Distance between the communication device and the satellite makes it suffers from high latency in terms of data transmission
GSM (5G)
GSM:
Global system for mobile communication
Allows mobile phones to connect to a network for calls and text messages
Connection Characteristics
There are several factors that a user must consider:
1) Strength
2) Range
3) Latency
4) Bandwidth
5) Storage Capacity
6) Connection
What is latency?
The delay when sending data across a network
What is Bandwidth?
Maximum amount of data that can be sent across a network at once
What is Connection?
Refers to whether a network is dedicated (uncontended) or shared between users (contended)
