- Description
- Used by wireless-enabled
devices (computers,
mobiles, smartphones,
etc.) to log in to the
internet. Wireless is exactly
what it says; there are no
wires to connect.
- A wired connection to a
broadband supplier.
Normally the connection
is via a network card in
the computer. Cable users
have an ethernet
connection from their
computer to the network.
- A wired connection via a
conventional telephone
line, which needs a
modem to convert signals
to and from analogue for
transmission

- Advantages
- Not fixed to a
stationary
computer. Can be
used wherever
there is a wireless
hub which is
accessible.
- Broadband
connections can
give better
reception and
are usually
faster than
dial-up
- Can use
existing
telephone
circuits which is
useful in some
areas

- Disadvantages
- Need to have access to a
wireless hub. Can be less
secure than wired
connections. Tend to have
slower data transmission
speeds than wired
broadband methods.
- Requires a base
which is wired in,
so it is less
flexible than
wireless.
- Older technology gives poor
reception at times. The
conversion from digital to
analogue signals can cause
errors. Tends to be slower
than other connection
methods.

- Bandwidth and transmission rate
Bandwidth is a measure of the available
capacity of a network (to carry data)
measured in bits per second. The
transmission rate is a measure of the
number of pieces of information that have
been transferred during a specific time
period, usually also measured in bits per
second. A high bandwidth means more
information can be carried in a given time,
so a higher transmission rate is achieved.
Insufficient bandwidth can result in
websites and servers appearing to run very
slowly.
