What's the point for computer optimization?

by: Ted Peterson

I am sure you've heard a lot of things about computer optimization. Everywhere you look you see ads that invite you to "boost your performance" or "improve your computer". So, what's the idea? Is anything true about it? Does your computer really need optimization?

Unfortunately, it does. There are many weak zones in Windows operating system. Here are a few of them:
- registry
- hardware management
- internet connection

Registries are Windows's internal database. All sort of information are stored there, from hardware and drivers info to applications' settings. After each removal of any device, like a printer or video card, pieces of information remain there. The biggest problem is when you uninstall a program. Unfortunately, many applications fail to erase all their data on removal. A solution for this is to run "regedit" and manually search for all references to the program and erase them.

By hardware management I mean memory and hard-disk management. As you know, each program uses some of your computer's memory. Memory allocation is determined by how much the program needs and, of course, if the resource is available. When the application stops, the used blocks of memory should be freed. But this is not happening all the time. So, when a new programs requests memory to run, your computer will slow down because it will compete with other applications for the remaining resources.

The same situation appears when you remove files from your computer. They are not really erased. They remain on your hard-disk and affect other files that you want to read or write. It's the same principle as described above regarding memory usage. To avoid problems you should use at least once a month a hard-disk defragmenter, in order to clean remaining pieces of information.

Because so many people use the Internet today, internet speed has become very important. I am talking about download speed and browsing speed. Actually it's the same concept. When you browse a webpage, you computer creates by default a channel with the page's server and starts downloading it. Download speed is of course given first of all by your internet subscription, but there is something that affects it too. The connection channel can be single threaded or multi threaded. As I said that channel is by default single threaded. What your computer should do is to break the downloaded file (image, text, archive, etc) into several smaller parts, and create a download channel for each of them. After they are all downloaded it should, of course, rebuild the source. That is what all download accelerators do.

Those are only a few ideas why your computer needs optimization. Registry tweaking, memory flushing, hard-disk defragmenters and an accelerated Internet connection would speedup your activity because you won't have to loose so much time waiting...

You can find several software releases that would do the job on CoreDownload, a software archive with over 23.000 titles to choose from.

How Video can be used Effectively Online

A powerful way to convey your communication messages to your audience is to be able to have your promotional video available on your website.

Yet, we have probably all experienced visiting a website and clicking on a video only to have to been irritated that the content is not viewable or that the sound is inaudible. The result is we leave the website in frustration.

So how do you make sure the video content on your website can be watched by your audience? It all boils down to how you want your viewers to access your video file and the level of video quality you want your movie to be played at.

There are two different ways of sharing your video file on the web:

1. Streamable Video

This is where the viewer is able to download sections of your video (otherwise known as "streaming"), while the video is playing. The main benefit of this method is that the user does not have to spend time downloading the complete video before viewing.

There are three major streaming video formats ? RealVideo (RM), QuickTime (MOV) and Windows Media (WMV). These are playable on Real Player, QuickTime Player and Windows Media Player respectively. Windows Media Player is widely available on most PC's, as it is part of Windows Operating System. The other players need to be installed.

The only negative with streamable video is that the quality of the video is dependent upon Internet connection. In addition, it has the annoying habit of dropping video frames because the streaming software has to adjust the data rate based on the speed of your Internet connection, in order to keep playing the video.

2. Download and Play

This is where the viewer needs to download the entire video first, then play it on their video player application. The main advantage is that the video quality is not affected by Internet connection speed.

However, it can take some time for the video to download if the file is large.

So which format do you choose?

In a world where first impressions always count, it is extremely important for companies to appear professional and trustworthy at all times. Marketing videos with poor picture quality are likely to reflect a poor quality company in the mind of the viewer. Consequently, we always recommend the download and play option. This is because it allows for high quality video content to be viewed.

However, as you don't want viewers to give up on downloading your video, we only recommend that short video clips are inserted onto your website.

This means your website users will be able to download a short video at a high quality picture resolution that will portray your company in the best possible way.
