Computer networking
is a very wholesome endeavor as almost every organization, including homes,
have some sort of computer networking in use. Computer networking allows for
collaboration by sharing documents, pictures, videos, and other media that can
be for profit, education, entertainment, fun, and anything in-between.
This canvas will discuss simple computer networking technologies and the roles they play in everyday situations, and in my life. The idea is to share some knowledge gained from real life situations while learning as much as possible through collaborative and interactive discussions.

My Network Story ... part 2
Here goes.... this was hard to publish!
I couldn't get enough of Commandos and wanted a computer at home for myself. Back then there was no concept of the internet and the computer I started out with was brutally slain by my own hands which meant I could only play Commandos when I went to school. Yeah, being captain of the chess team, practicing the high jump, and training for the Dacosta cup team, studying for A level Math, Physics, Technical Drawing, and the General Paper, I would still find time to play my Commandos...did I love me some army tactics or what.

IPv6 - It is Upon Us
World IPv6 day is June 6, 2012. On this day, ISPs, web hosters, some major web sites, and some major organizations will turn on IPv6 and leave it on indefinitely. This will be a ground breaking day for IPv6 and the major shift from IPv4 ..... maybe we are staring down the millennium bug all over again.. or maybe we are about to really unleash the power of the internet.
IPv6 is much like doctors developing a new cure. Think about it, when's the last time you've heard of a cure for anything? People still get the common cold and some are fashion deprived..... couldn't one of these many doctors find a cure for one of these things... I have nothing against doctors... I digress!
IPv6 will firstly cure the lack of addresses we've been encountering with IPv4. The internet will now be a truly globalized landscape where every device will have an IP address that is routable.
The best part is IPv6 has a bigger round number that IPv4!

Your Personal Tracking Service ... part 2
MAKING A CALL.. This is how the system works.......
Two people on a phone call create an end to end connection that works much like two computers sharing data. Between them, exists a network of routers and switches that use a host of protocols and services that facilitate the transaction. From a networking standpoint, a cell phone operates in a similar fashion, so we can look at a few simple scenarios that illustrate this:

Your Personal Tracking Service ... part 1
What a glorious invention. We are coming from Alexander Graham
Bell's 1876 invention of the simple telephone all the way to
the iPhone, AnDroid, and Blackberry cell phones of today. Can you imagine what
it would be like not to have cell phones to communicate and stay in touch
all the time? Can you? The transition has been explosive and is seen when you compare the early invention to where it is now.

Wireless Networks - Wi-Fi.. a blessing or curse?
Most if not everyone
connecting to the internet these days would have used some kind of wireless
connection at some point. It seems the CAT5 cable is going out of style when it
comes on to personal and even business uses.
Wi-Fi is hip and cool and you
don't have to contend with the cables that are time consuming to run and
sometimes hard to look at, and are at times, hazardous. Wi-Fi is really such a
simple piece of technology we use everyday that it almost becomes a requirement
for every household. Yes, you need electricity, water, and wireless! I'm just
now waiting for the 'Wi-Fi is the next best thing since sliced bread' phrase to
start taking over the airwaves.

My Network Story … part 1
I grew up with a
computer at home in the mid 1980s. I don’t remember much about it now but it
was a RISC (reduced instruction set computer) that only allowed you to do very
basic things with the hardware and software. Yet I do remember that I only ever used that PC
to play Pac Man. The best game of that era that allowed you to eat ghosts when
they turned blue. Oh I wish I could get a
real pill that turns my ghosts blue on my angry days…face it, everybody has a few ghosts.

IPv4 and Jamaica
It is not widely known that the IPv4 addresses have all been used up across the world. If you're not in the IT industry, it might not even matter to you anyways. There are even some people that will say the IPv4 ranges have only been distributed but not used up. Yet IANA has no more IPv4 addresses to distribute even if I needed just one, so I think i'm right in saying they are all used up and not may people will argue with that point. ISPs across the world, including those in Jamaica, will need a solution for the future.
