Desktop Applications Vs. Web Applications

Software application development began with desktop applications, which could be used on standalone machines only. However, with the advent of internet and online commerce, web application development gained importance. Word processors and media players can be considered to be typical desktop applications, while an online shopping cart on an ecommerce website can be considered as a web application.

By definition, a desktop application means any software that can be installed on a single computer (laptop or a desktop) and used to perform specific tasks. Some desktop applications can also be used by multiple users in a networked environment. Web application development, however, soon started replacing desktop applications for reasons of portability and better functions from usability point of view. Web application development is usually made on client-server architecture and use a web-browser as the client interface. This is one of the reasons why web applications are so widely getting popular. Though web applications offer a slight advantage over desktop applications, there is a very narrow chance of desktop applications becoming outdated. The primary reason for this could be the security issues and legalities associated with web based applications.

Following is a basic comparison on desktop and web based applications based on certain parameters:

• Maintenance - web based applications need to be installed only once where as desktop applications are to be installed separately on each computer. Also updating the applications is cumbersome with desktop applications as it needs to be done on every single computer which is not the case with web applications.
• Ease of use - desktop applications are confined to a physical location and hence have usability constraint. Web applications development on the other hand makes it convenient for the users to access the application from any location using the Internet.
• Security - web applications are exposed to more security risks than desktop applications. You can have a total control over the standalone applications and protect it from various vulnerabilities. This may not be the case with web applications as they are open to a large number of users in the Internet community thus widening the threat.
• Connectivity - web application development relies significantly on Internet connectivity and speed. Absence of Internet or its poor connectivity can cause performance issues with web applications. Desktop applications are standalone in nature and hence do not face any hindrances resulting from Internet connectivity. Connectivity also significantly affects the speed at which desktop and web applications operate.
• Cost factor - web application development and its maintenance involve higher costs and mostly recurring in nature. Desktop applications are purchased one time and there are not continually occurring charges. However, in certain cases, maintenance fees may be charged.

Having considered the basics of desktop and web application development, the selection of a suitable type will depend on the business needs and factors discussed in the comparison given above.

Ordering Computer Parts: what you need to know

From cheap laptop messenger bag. So your Computer bogged down and now you are on the hunt for a brand new Computer. The problem is the friend who helped you choose your old Computer is living in another state now and frankly, you are just lost when it comes to Computer shopping. 

First things first, before you decide to buy a new Computer, make sure that you know what the problem is with your old one. You may not realize it but you may not even need to change the whole Computer. Sometimes, you just need to change the peripheral parts like the keyboard or the monitor. But when the CPU or the central processing unit is the one with the problem, you might need to start budgeting for a new one. This  is where all the Computer Parts can be found. Computer Hardware is the one that makes the Computer work.

Here are some of the thins that you need to know when Buying a Personal Computer. 

What's there to fix?
Just because your PC does not work does not  mean that you will need to change the entire set. Often, when it bogs down, only one part is the culprit  and you can change that part while  still retaining the others. Of course, this depends on what that part is. Sometimes, you also need to change a major part of the Personal Computer and doing so  will cost you the same amount of money that you will spend when you buy a new one. So before you start to budget, have it checked. 

What do you need it for?
Another important question to ask yourself is what you need the Computer for. This will determine the kind of Hardware and specifications that you need to buy to satisfy your requirements. A person for instance who is more into word processing will not need a Desktop Computer with a powerful graphics card  or sound card. Someone who only  use it for music and not for word processing will need a big hard disk space and of course a set of powerful speakers. 

What is your budget?
A lot will depend upon the amount of money that you are willing to spend. If you want a Desktop that will last you several years, be prepared to spend a little bit more than the usual. This way, you will be able to  choose the brands that are known for their long life  and sturdiness.

How difficult is it to change the case of a Desktop Computer?

Just looking to buy a new case for my desktop, and i was wondering if it was difficult or not to do so?

Well.. You have to unplug every wire, take out the video card, then you can unscrew the motherboard.. After that, you have to take out the HDD, power supply, and the dvd/cd burner/reader.. Then, you need to put the HDD into the new one, then the motherboard needs to be screwed in, then you need to put the power supply into it.. Next should be the wiring: the hard part is the little single and double pronged ones.. Then, you should put the video card back in and close it up.

You also have to make sure to ground yourself by touching a piece of metal.
Also, never mess with internals with the power plugged in!(Even if the power switch is off in the power supply, it is still dangerous)

Germanmade handmade wood and leather g.2 iPad-Case for iPad 2 (TUAW)

Most premium iPad cases are pretty similar. Some are bags, some flips cases,
some sleeves -- Germanmade has done something a bit different with their book-
style case.

**Construction and design**

Made from leather stretched over veneer, the case has a uniquely organic feel.
From the outside it looks just like a leather-bound book. The sides resemble
mottled pages, with the hardback cover completing the look.

Both the wood veneer and surface cover material are exquisitely finished,
giving a genuinely luxury feel. The inside of the case is finished in natural
wood and an inlay color of your choice, in this case white. It's put together
really well too, feeling pretty solid all round, yet reasonably light for the
size and amount of material used. While I wouldn't want to drop the iPad in
the case, it's likely to be held pretty well; although the case itself is
likely to come off pretty knackered from a fall of any decent height.

**Use**

The case fits the iPad 2 very well, holding it securely in place with small
rubber friction pads in the corners. The front flap is held in place by a thin
strip of black elastic ...
