Computer Networking and the CCNA


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.

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.
