In order to connect to the Internet, you require a device called a
router . A router forwards data packets to the device requesting it.
Without a router, you have no way of connecting to the Internet from
Bandwidth a measurement of capacity. Bandwidth is the number of
bits that can go through the network connection in a second.
Bandwidth is always measured in bits, however:
If you have a slow internet connection, your reading will
probably be in bits per second (bps). This will likely result in you
being unavailable to stream video of any kind without high
amount of buffering, as well as slow webpage loading times.
If you have an average connection speed, the one for most
households now in the UK, your bandwidth will be measured in
megabits per second (mbps). 5mbps and above will allow you to
stream HD videos with little to no buffer, however if multiple
users are on the same network, it will likely result in poor
connections. A fibre optic network typically sees speeds of
30mbps or more, which will be plentiful in streaming multiple
contents and viewing webpages/downloading files.
A very high bandwidth, not common at all in the UK but in some
places in the world, receives bandwidths of over 1 gigabyte per
second (gbps). In honesty, it's wasted, because not a lot of
technology can take that speed appropriately.
Latency a measurement of delay. Latency is measured in
milliseconds. It's the delay between a bit leaving one device, and
arriving at the other.
When playing video games or on Google you want a low latency
as you want it to be quick.
If you're browsing on the internet, it doesn't really matter what
the latency is, you won't be affected greatly.
REMEMBER! You want a HIGH BANDWIDTH but LOW LATENCY!
