Lost Something On Your Computer? It May Not Be As Bad As You Think

Lost Something On Your Computer? It May Not Be As Bad As You Think

Just because you can’t see it, or can’t find it doesn’t mean that its not there! I would say at least 90% of people who use a computer on a regular basis have no idea how it actually works. They think that things like icons on their desktop will make their computer run slow. Many things that because they have a slow computer it will cause their Internet to be slow. Others think that “Windows” is the computer and they don’t realize that it’s just another piece of software like every other program running on a computer. Finally many people think that when they click and delete something off of their computer, and wipe it from their trash bin that the information is actually gone. If you think that is the case, and you think you have lost your information for good, think again, cause you might just be in luck!

When information is stored on your hard drive or hard disk, it is stored in things called sectors. When you delete something off of your computer through Windows or Linux or Dos all it is doing is telling the computer that those sectors are now available to be written over. The computer doesn’t actually wipe them clean, which would be useless when it could just as easily write over them. So if you have a virus or a computer illiterate roommate that happens to delete the important files off your computer, then you might just be able to get that information back. There is one catch, its not easy!

Not only is it not easy, but also 99% of people don’t have the technology, know-how or resources and education to do it themselves. This is why there are professional companies that specialize in data recovery, and believe me, they charge tons of money.

Data loss occurring from an actual hard drive failure such as overheating and melting important sensors or an electric shock that fries components might actually result in permanent data loss. Yep, so sometimes data recovery cannot restore lost files. This is why data security is a smart, preventative measure. Backing up data on multiple hard drives and CDs and DVDs and on multiple computers will prevent disastrous things like permanent data loss from occurring. Be smart – back your files up, it will cost you less to back up on hard drives than it will cost you to recover files directly from your hard disk.

CNC And CAD – Computer Aided Design

CNC And CAD – Computer Aided Design

CAD stands for Computer Aided Design or Computer Aided Drafting. CAD was developed in the early 60s. Today it is the premier way to design, develop and optimized products. People use CAD every day to design virtually every product you see. Generally, designers use CAD to design a product, and then produce prints to manufacture that product. A print is a picture of a part or assembly that is very exact. It includes the dimensions and a parts list used to manufacture a product.

CAD is the use of computer based software packages that assist engineers, architects and other design professionals in their designs. CAD is the part of the main designing process and involves both software and sometimes hardware. Current software packages range from 2D vector based drafting systems to 3D solid and surface modelers.

Computer Aided Drafting software packages can generally be broken into two groups. The groups are 2-D drafting packages or 3-D drafting packages. Most all software packages are moving to 3-D design. 3-D design is really the next generation of CAD. Utilizing 3-D design, engineers can make a model of their product. They can then look over this model for any apparent defects before it is ever made.

CAD is used to design, develop and optimize products. CAD is mainly used for the engineering of models and/or drawings of components. It is also used throughout the engineering process from concept to design of products. These products can be used by end consumers or used in other products. For example, you can design a bolt in CAD, and then use it in a Sub-Assembly in a planetary, which is a part of an earth-moving machine. CAD is also used in the design of tools and machinery. Finally, it is used in the design of all types of buildings from sheds to shopping malls.

What Is An Activex Control And How Is It Related With The Registry?

What Is An Activex Control And How Is It Related With The Registry?

ActiveX is a technology that was developed by Microsoft to enhance the display of images, video and animation in their browsers. ActiveX components are a set of rules that guide the browser to display hi-resolution images and streaming video properly.

It should suffice to say that ActiveX is a technology that was developed to bring the power of Object Linking and Embedding or OLE as it is popularly known, to empower web browsers and particularly Internet Explorer, to display such objects. When web pages with embedded ActiveX components are downloaded, the corresponding controls are also downloaded and automatically launched by the operating system of the computer. This can, over some time, clutter up the registry with unwanted data and controls, thus slowing down the system drastically. This will mean having to clean up the registry with a registry cleaner periodically. ActiveX controls are actually used by windows to display very rich interfacing activity such as animation, video images, virtual reality that used 3D technology, high resolution images and the like.

ActiveX Prompts For Registry Cleaners

When downloaded into your computer, an ActiveX control is actually packaged as an .OCX file. There are cases when more .OCX files are downloaded and needed for a web page. The .OCX files like ActiveX controls need to be registered on your system before they can be used. Registering means that a program capable of doing this, queries the ActiveX control and saves specific information about it into Windows Registry, so that the operating system can find it and therefore be able to use the ActiveX control. However, one must keep in mind the importance or cleaning up the registry periodically. The Internet has the best registry cleaners available free. So, make use of them to keep your system running smoothly.

Pro’s and Con’s Of ActiveX Controls

It is important to understand that with all the ‘pros’ of ActiveX technology also come a few ‘cons’ as well. ActiveX is a very powerful tool and is sometimes used by individuals, with a flair for the technology, to create ActiveX controls with malicious intentions. These ‘corrupt’ ActiveX controls can wreck havoc on your system and leave you helpless for no fault of yours. After all, you know that ActiveX is supposed to help your system run some programs, right. So why not download an ActiveX control when you are prompted to do so? It is for this reason that Microsoft has developed the ActiveX security system.

In Windows XP operating system, this security system is embedded in the Internet Explorer. The registry of the system automatically blocks the download and installation of any ActiveX component in the Registry of the computer. Apart from this is an ActiveX component has to be installed the computer will prompt the user to check for the signature of the component. If the ActiveX component is registered with Microsoft the ActiveX is verified as authorized and is allowed to be installed in the registry of the computer. If the ActiveX component is not verified the systems offers the user a choice of not installing the ActiveX control.

Some Advise For Internet Explorer Users

If you are using Internet Explorer you should ensure that you are using a security level set to Medium or above in Internet Explorer. You can do this by going to tools in IE and select ‘internet options’ then click on ‘security’ and slide the level to medium or higher. Now, after reading about the entire automatic downloads of controls and stuff, it makes sense to download a free window registry cleaner and use it periodically to clean the registry of your system. There are enhanced registry XP cleaners to clean the complex registry of Windows XP as well.
