B1 : - Connectivity
Synchronise (Sync) – match up and pull together, e.g. making sure multiple devices have the same copy of relevant files
Bandwidth - available amount of data transmission capability
Fibre optics - collection of fine silica strands which use light to transmit data at high speeds
4G - 4th generation, accessing internet at high speeds via mobile
Devices can connect wireless or hardwired. Before wireless technology was available, computers and devices only connected via a cable. Nowadays we expect the devices to be portable and connect to the internet wireless.
Hardwired – permanent connection between components of IT systems.
Computers and electronic devices are now all able to connect to each other and as customers we like to buy devices which are able to interact with other devices for example a smart TV or Garmin watch.
Peripheral devices
Security: Organisation will put security systems into place.
e.g. a school will hold personal data about a lot of students such as date of birth and location
Examples - printer, mouse and keyboard
Fibre optic
Advantages - fastest transfer speed, can go over long distance
Weaknesses - expensive
Wireless
Wired
Advantages - no physical wires
Disadvantages - slower than fibre optic, additional costs (router)
Used still in broadband with telephone connections
Advantages - security, no sniffing, reliable, fast
Disadvantages - physical wires can be damaged, takes up space
