The choice of computer mouse is a very individual thing and depends on many factors:

  • How many hours a day you work at your computer?
  • Is your primary computer a desktop, a laptop or notebook or even a tablet; but you won’t be needing a mouse if it is a tablet, will you?
  • How big your hands are.
  • Do you want/need to use wired, wireless or bluetooth?
  • Whether you use the scroll function or not.
  • Do you suffer from wrist pain?

In some of these instances, the cheaper type mouse that comes with your computer will serve your needs adequately, but if you, like me work for about eight hours every day, the comfort and functions of your mouse are particularly important.

On the left below is a photo of the first mouse I paid in excess of $60 for and never regretted it at all. It was comfortable in my largish hands and I didn’t ever suffer any wrist pain even though I worked at my PC sometimes up to 12 hours in a day. The day I dropped it on the tiled floor and broke it was a very sad day for me.

Luckily I was able to buy another different model  but with the same profile within a couple of days. That one too has died lately so I’m looking for a new one, the Kensington mouse on the right below might well be the one since I have had a word in Santa’s ear!

The logitech 2nd from left has served as my laptop mouse for a couple of years – it does look a bit battered, doesn’t it? Very similar profile and quite comfortable. The third photo shows my big hands – imagine my right hand wrapped around one of these tiny mobile models! However, I do carry a retractable one around in my laptop bag, as a backup and the occasions when an extra mouse is needed to test someone’s computer.

 History of the computer mouse

Tracking Technology

.
Did you know that the name mouse is derived from “Manually Operated User Select Equipment”? This makes the argument about whether more than one computer mouse should be called computer mouses or computer mice (as we do for the rodent variety). It seems there has been no absolute ruling and generally computer companies avoid the issue by calling them mouse devices. Probably mouses is technically correct, but it sounds awkward and people tend to use mice for the plural form.
.
The original design for a mouse was mechanical; the mouse had a ball in a compartment underneath and embedded around the edge were some little rollers. These would clog up from the dust and dirt from the user’s desk and needed cleaning to keep the mouse running smoothly (I did this countless times when clients or friends complained that their mouse wasn’t working properly). There were also four sliding type feet that clogged up as well, but these devices were a boon when the alternative was just keyboard shortcuts.
.

Along came optical technology and made our lives so much easier. A small LED on the bottom of the mouse translates the movement of your hand into movement of the mouse pointer. Laser mouse devices work the same way, but using a laser instead af the LED. Laser mice have a higher dpi (dots per inch) which means they are more sensitive. For general users this extra sensitivity is not really needed, but graphic designers and gamers often appreciate the difference and make a laser mouse their choice.

Wired Connectors

.
The early mice (see above) had a serial connector plug, see picture below. Serial ports were the original standard for interfacing any device with any other device on a computer. Later, a smaller 6 pin Mini Din was introduced by IBM on their PS/2 personal computer and this led to the connector type being called PS/2. For many years PC’s had PS/2 connectors for both keyboard and mouse.
.
Some computers still come with two PS/2 ports, but more commonly they just have one, the USB (Universal Serial Bus) being the most common type of interface on all computers, whether PC or Mac. All USB ports look the same, but there is the original USB 1.1 and USB 2.0 which allows much faster (almost 40x as fast) or increased delivery capabilities. The ports are backwards compatible, so you can plug an old USB 1.1 device into a 2.2 port and it will still go.

Wireless

Originally the mouse device was connected to the computer by a cable using one of the technologies above, but nowadays you have the choice (an increasingly common one), to go with wireless. The early hassles of wireless connections seem to have been ironed out and wireless usually works very easily on any platform. Yay! So much more freedom.

.
wireless.
Radio Frequency – this is the most common type of wireless interface. A generic mouse operates on th 27MHz frequency and the mouse is powered by batteries. More expensive models can come with rechargeable batteries or charging docks for the mouse. They may use higher frequencies and have a longer range.

bluetooth.
Bluetooth was useful for lower speed devices like a mouse and was common on early laptops. They are also battery powered and use the 2.4GHz radio frequency to communicate with a receiver/charger supplied with the package or some other Bluetooth adapter...

RFIDRFID (Rapid Frequency Identification) technology uses radio-frequency electromagnetic fields to transfer data to automatically identify and track tags, which for a mouse is movement. Developed by a company called A4Tech, the mouse must be used in conjunction with the included mose pad, but the advantage is that it is wireless and no batteries are needed.
.

Wheels and Buttons

Nearly all mouse devices nowadays have three buttons, with the middle button also being a scroll-wheel. This scroll wheel is essential in my opinion to navigate up and down your screen and on web pages. Any other buttons, typically on the left hand side for a right handed mouse or on the RHS for a left handed mouse, can be programmed by the user to carry out different functions.

 

Buying a computer mouse

A quick search on eBay will show just what a variety of choice there for buying a new mouse – some are fun, some are fancy, some for serious gamers and some ergonomic models for users like me. So how do you choose?

Narrow down the options with these requirements:

  • Do you want wired or wireless?
  • Do you need laser or will Optical suit your needs?
  • What size – full-sized, medium or small (also called compact,  mini, mobile, laptop etc)
  • PS/2 or USB? USB is more common but if your computer does not have many USB ports, but does have PS/2 ports, using a PS/2 mouse (or keyboard) will leave an extra USB port available for other peripherals.
  • Scrolling – do you need left and right as well as up and down?
  • Buttons – does your work (or play) require advanced features?

A great place to see what is available is on eBay, even when you want to shop locally. The wide variety of mouse devices listed there will give you a good idea of all the functions and help you narrow down your choice.

A very useful tool I use, mainly for backing up online and sharing files within my own network , but it has the potential for much much more is Dropbox. Yes, there is an upgrade option, but you can use the free version very well. There is also an option to get more free storage space when someone you tell about Dropbox signs up.

So what does it do?  It lets you share your files and folders with others by sharing an existing folder on your PC or creating a new one to share. Once you add other members to the folder, it will appear in your friends or colleagues own Dropbox just as it does in yours. Any changes made to the shared folder’s contents will appear instantaneously to everyone who is a member of that folder. You can create a folder in your Dropbox folder just as you would anywhere else on your hard drive.Can you see the potential in this?

There are two ways to setup Dropbox, as a local application or online. The procedure is pretty much the same either way. Continue reading

Bing, Yahoo and Google

Now, while Google still has by far the greatest amount of traffic at approx 62%, the agreement by Yahoo & Bing (Microsofts new search engine) to share resources, means that when their respective search shares of approx 19% & 13% is combined, it will provide much bigger opposition to google.

So should this concern you? Probably not unless your business uses search traffic to make sales. Lets assume for a moment that it does. And did you know that facebook search is powered by Bing?

What can you do to increase search traffic to your sites from Bing? Well first of all, you can submit your site to Bing here and submit a sitemap here.

Bing has just released their updated Webmaster tools, not as comprehensive yet as google’s webmaster tools, but definitely a step in the right direction. Open an account to access these tools using your Windows Live ID (or create one if you don’t already have one).

To see how Bing crawls and indexes your pages, you can add your sites to your account. How to do this is set out quite well in the section “Add a Site to Your Account” under “Sites List”. You can only add your own sites and you must verify ownership before they can be added – you don’t want other people looking at your results!

The only hitch I encountered was adding verification to a wordpress blog that didn’t reside in a public_html folder so meant I couldn’t just upload  the xml file, as suggested in Option 1. Using Option 2, I had to search around my blog admin section to find the file containing the <head> tag. In fact, it didn’t have one just like that, but it did have an </head> in the file header.php, so placing the <meta> tag just before that worked fine .

If you need more details, proceed as follows:

In your wordpress admin area, click on Appearance, then on Editor. This will bring up an open file with the html code showing. Go to the list on the right hand side under Templates and find Header (header.php) & click on this file. Now, have a look in this file for  </head>  something like this:

<?php wp_head(); ?>
</head>

Now paste the meta tag code copied from Bing in between these two lines and then click the Update File button at the bottom. Go back to Bing webmaster tools now and verify your site.

Newly added sites will take up to three days to begin showing data, assuming they are getting some traffic, of course.

Hope this helps someone.

There is more to your  computer than the monitor, the keyboard and the mouse, though most of the other components are hidden away.

In that big box that you often complain about being too bulky, lies the heart of the computer.

It houses all the vital parts that make your computer fully functioning.

Get to know some of these parts.

  1. The processor or CPU (Central Processing Unit) determines how fast your PC will be & is perhaps one of the vital parts of a computer, if not the most vital. Having a fast processor will allow your computer to convert data faster Continue reading
