Computer Networking Simplified

So what is computer networking? To the uninitiated this term may sound intimidating but you may have already come across it or have even used it either at work or at home. For those new to computer networking, simply put, a network refers to a system where two or more computers are connected to each other. This is done so people can share things like information or computer hardware, like a printer for instance.

Now there are several things you need to set up a computer network. The most basic system consists of a protocol, NICs or network interface cards, cable and a hub.

A protocol is a set of rules that the computers have to follow in order for them to "speak the same language". For example, http is a protocol. If you want to be able to access a website from your computer that works on http, the website you are accessing must also operate on the same protocol otherwise you will not be able to read the site.

NICs are cards that you put at the back or side of a computer. This allows the computers to communicate with each other. A cable is simply a wire that connects the computers together and the hub is a device that controls traffic, for example, information that one computer sends to another.

Now this is a list of items for a standard network. You're going to need a different set of devices if you are going to go for wireless networking.

How does a computer network work? Let's say for instance, you want to send information from your desktop to your father's computer. The NIC on your PC transfers the file through the cable into the hub. The hub then transfers the data to your father's computer. If each of the units uses the same protocol then the information is accepted by your dad's computer and he will be able to open the file you just sent.

There are two types of networks: the LAN or local area network and the WAN or wide area network.

The LAN is a very simple type of network where all the units you connect are located in one place. There are two types of LAN, peer to peer and client server. A peer to peer network is where two or more computers are connected to each other directly. For example, computer 1 is connected to computer 2, computer 2 is connected to computer 3 and so on. The computers are dependent on each other so if one unit experiences problems, the others simply will not be able to connect to each other. The client server type is where all computers are connected to a main unit. This is more convenient because if one computer has problems, the others will not be affected. You will still be able to exchange data.

An example of a WAN is the internet. As you can see, this is a very large type of network allowing millions …

Good Browser Titles

A lot of people underestimate how effective a well written browser title is, in terms of SEO.

Seriously, do not underestimate this simple rule. A good browser title can be a significant boost in search engine rankings (especially Google and Yahoo).

So how to write a good browser title?

Well firstly capitalize the first letter of every word except prepositions (of, and etc).

I'm not sure if this benefits SEO in anyway but it's correct grammar wise so will make your site more look slowly more professional to grammar geeks. Perception and conjecture based on image, layout, usability is key to the influence of a good site.

Anyways, the most important thing is keywords, obviously. But you do not want to just ram pack the title with keywords in a spam fashion. Type the title naturally, not too long, not too short, just presentable and readable, write it for humans!

You just have to make sure it describes the page well so that the keywords in the title will match the keywords on the page and if you can, the page header.

An example:

Say your page is about … health issues with smoking.

You've got something like:

"Info and Help with Smoking Health Issues | Lung Caner | Smoking Kills!"

It's good to sometimes include a question also as a lot of people type query's rather than just random keywords.

But remember, you need to make your title stand out in some way otherwise it will just get lumbered in with the rest, but do not go to the other extreme as ending up on the spam end of things! …

Is Amazon a Good Solution to Host Your WordPress Website?

After facing the fact that I need a faster hosting provider, I finally decided to try out some of Amazon's hosting products. Amazon has so many web services that it can be a little daunting to get started with them, but I decided to give it a go.

The first thing that I looked for was the ability to host WordPress websites. After a little research, I found that Amazon had just introduced a program for WordPress. Using their new "LightSail" product, I discovered that it was actually pretty straight forward to configure and load up WordPress. There are several other popular CMS apps as well, such as Drupal and Joomla. If you are interested in an e-Commerce solution, Magento is also supported.

Lightsail is not for large deployments, but it's pretty darn easy for smaller requirements. In a nutshell, you sign up, put in your domain name, set up WordPress, set up your DNS zones, map the static ip address that's assigned to you, and it launches.

When you go to launch one of the apps, Amazon refers to them as "instances". You would select the instance that you are interested in (WordPress, Drupal, etc) and follow the step-by-step directions.

1. The first thing is to name your instance. If you do not name it, Lightsail will create a name for you. Amazon works in zones, and in my case, it's usually Virginia. You can change the zone if you like, but I've found it's better just to leave it at the default zone.

2. You will also pick your instance plan, which is the monthly fee that suits your requirements.

3. You can also run other various scrips and choose either the default SSH key pair or change the key pair. As above, I always stick with the default.

4. Then click create. It takes a couple of minutes and then a page comes up with a public ip address and a username to connect to the instance. You will need your private key from your Amazon account, so if you do not have one, you'll need to create it.

5. Bitnami is used to connect to the new site. But after, you've loaded WordPress, you login exactly the same way with every other hosting company. Bitnami is pretty intuitive and does not take more than 15 or 20 minutes to learn how to navigate around.

There is also some project guides and videos as well to help with the install. According to the WordPress project guide there is only 5 steps, but in reality, it's more like 8 steps.

I loaded this up a few weeks ago, so I have not had time to fully build it out, but I had no problems loading the theme. I'm also using an AWS plugin (free) that will copy any media files to Amazon S3 and serve from S3 Cloudfront. Hopefully, this will cut down on load times for my pages.

It takes some getting used to not having cpanel, …

Reason # 1 – You can get faster results if you buy your visitors.

The Basics of Usenet Technology

Usenet technology can propagate anyone’s posting around the world in a very short amount of time, oftentimes within a day. This system is decentralized and relies on a network of servers that share information with one another at regular intervals. Everything that you post on the Usenet system is tagged with a unique ID number. This allows the servers to avoid copying the same information twice and, since the late 1970s, this system has proven itself as one of the most robust and adaptable of electronic communications designs.

Usenet involves a transaction between you and your news server at first. Normally, you would read a posting on a newsgroup and decide to respond to it. You do this from within your newsreader program. Once your post is finished and you’re ready to add it to the discussion, you send it to your server. Your server updates the appropriate newsgroup with your contribution and then, at regular intervals, sends its information to other servers. They, in turn, send their information to your server, which they have gotten from still other servers. Each server within the system represents a separate entity that has its own administrator. There is, however, no administrator for the system as a whole, nor is there one central server that could go down and stop the Usenet system.

Some servers are very large and act has hubs for the Usenet as a whole. If one of those servers crashed, however, the information would simply be passed along by different servers. Your ISP may provide you with access to a server or they may not. They’re not as commonly offered as a basic part of Internet service anymore and, for that reason, many people will have to use third-party access providers on the Internet to get service.

Newsreader programs are required to participate in Usenet newsgroups. These readers are sometimes included with free email programs. There are also paid versions of this software available that offer more features and other enhancements. Some readers also allow you to handle different types of files as the abilities of the Usenet have long ago become far more diverse than handling simple text posts. Usenet servers remain popular today with people in the scientific community, hobbyists and people who just like socializing with others online. It may be similar to Internet forums, but Usenet has a much different technology that drives it.…
