2. Wired (Via Ethernet Cable)
 Wired connection is probably the simplest way to connect.
The most common form of wired connectivity is probably
via Ethernet Cable. It simply allows you to connect to the
internet or any other electronic device that is internet
enabled (by either using another Ethernet cable or is
connected via Wi-Fi). Generally, they used to be made out
of coaxial cable however nowadays are more commonly
made out of a twisted pair (two conductors tied together)
or fibre-optic. An Ethernet cable is normally connected to
a computer from a router or server.

3. Wireless (Wi-Fi)
 Wireless (Wi-Fi) works in exactly the same premise as
Wired (Ethernet) but it is connected wirelessly, hence the
name. It is only enabled if there is a wireless router in the
vicinity.

4. Bluetooth
 Bluetooth is another type of wireless connectivity that is
commonly used. It is generally only used over short
distances and mainly used to transfer data from a small
handheld device to another handheld device or a
Laptop/Desktop Computer. It uses short-wave radio waves
to connect. Due to this short-distance connectivity, it
effectively creates a PAN (Personal Area Network) and
enables a very secure network

5. FireWire
 Fire wire (IEEE 1394) is a type of wired connectivity that
was developed by Apple Inc. in 1980-1990. It provides high
speed communications and isochronous real-time data
transfer (real-time data transfer performed at regular
intervals. It is comparable with USB but USB is far more
well-known and therefore sells more and much more
successful.

6. USB (1.0,2.0,3.0)
 USB (Universal Serial Bus) is an industry standard that
defines aspects associated with connectivity (Cables,
connectors and communication protocols). It is the one of
the most common connection types, and the USB
connectors (portable electronic connectors that use the
USB standard) are normally colloqualised just as ‘USB’,
which is technically incorrect. There are many types of
USB and these normally refer to an improvement in speed
(e.g. USB 1.0 is slower than USB 2.0)

7. New - 4G LTE
 4G LTE is a very recent connectivity technology used by
Apple Inc. in their latest product, the ipad HD. It uses the
old analogue T.V signals to transfer and receive data at
high speeds.
