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
