What Is The Safe Approach To Clean My PC Avoiding Much Hassle

February 27, 2010 By: lilybird Category: Software

Has a surgeon ever told you that, though they are an expert and can do the simplest they can, the operation still has some inherent risks? Visualize replacing the surgeon with some cheap or free software. I would not clean my PC that way.

There is no really safe approach to scrub your Registry, only safer ways. And since this is often an inherently dangerous job, the safest possibility of all to not do it. I grasp some specialists say you should clean your Registry frequently to improve operation. I differ. Clean your Registry solely if Windows includes a significant issue and zip else works.

If you must clean your Registry, back it up first. Most Registry cleaners can do that for you, except for additional shield, execute it yourself, first. One manner is to make a Restore Point. In XP, choose Start, All Programs, Accessories, System Tools, System Restore. Select Create a restore purpose, click Next and follow the wizard. In Vista, click Start, sort sysdm.cpl and press ENTER. Click the System Protection tab, then the Produce button.

If you don’t trust System Restore (and I can perceive why you would not), you’ll be able to use the free Emergency Recovery Utility NT (ERUNT). A minimum of you can if you are not using Vista. Although the ERUNT home page guarantees it works with “Windows NT/2000/2003/XP/Vista,” I’m not the sole person to get that it has serious Vista issues.

And build sure you utilize your Registry cleaner’s backup feature, as well.

Once you’ve got secured your Registry, open your cleaner, close all your different programs, and start the process. When scanning your Registry, the cleaner will display a list of entries it thinks you can and ought to delete.

Honestly, I would like I could give you concrete, reliable advise on judging this list, however I’ve never really found any myself. What do I do? I take a deep breath, cross my fingers, and “fix” each drawback the cleaner finds. Therefore far, it hasn’t created anything worse. And if it does, I’ve got backups.

Registry cleaning software is suited for anyone who is unsure concerning making manual changes to their registry. There are several registry cleaning programs out there to remove unwanted entries from your registry. Examples of registry cleaning software embody TweakNow Regcleaner, Registry Mechanic, and Registry Healer.

Personally I take advantage of software to clean my computer. These programs all primarily function in the identical method – they scan your registry and take away errors like missing references to files. It is necessary to find what registry cleaning software works best for your needs. All of them can offer you an inventory of results of what entries or safe or not safe to delete. Some of them, like Registry Mechanic, allow you to create a backup using their program. The backup will be easily restored if the system becomes unstable.

The Evolution Of The Ipod – Read How The Ipod Became A Lifestyle

February 27, 2010 By: lilybird Category: iPhone/iPod

When in 2001 apple published the first verison of the ipod, nobody could imagine what a high influence the whole ipod thing would have nowadays. Throughout the time, apple turned the common mp3 player into a fashion product and to some sort of a status symbol. Ipods are cool and trendy.

The first ipod had a memory capacity of 5 GB. This could be reached with the use of a mini 1,8“ hard drive
, where the most other mp3 players use flash memory. The disadvantages of the hard drives are, that they are slower than flash memory, and not very break-safe. So if you drop a HDD the chance is pretty high that it will be damaged.

The controller of the ipod is called Touch Wheel because it is touch sensitive. With more than 100 sensors it tracks the rotation direction of your fingers to scroll through your tracks. But it also has five buttons, play/pause, forward, backwards, menu and the middle button. In the newer versions they are integrated into the Touch Wheel, now called Click Wheel. The first time it was implemented was in the iPod mini (2004).

2005 the iPod mini was replaced by the iPod nano model. The first generation was equipped with 1,2 or 4 GB of flash memory, and had enormous reduced dimensions compared to the normal iPod model. It also comes with an color display. The third generation of the ipod nano was the first which could play videos. But the first color display was implemented on the iPod photo, already in 2004.

On the way to the iPod touch, there first had to come the iPod shuffle. A mini mp3 player without a display. The only options you have are to shuffle the titles, like the name says, or to play them in row. No single title selection is possible. With its very small size the iPod shuffle is perfectly for jogging or biking.

The iPod touch is the newest model of the iPod family. It was published ca at the same time as the iPhone, and has nearly the same functions as it, beside the mobile phone functions.The iPod touch has the possibility to install software (Apps), play music and videos or even whole films. But it has no camera like the iPhone. It also has a multiple touch touchscreen. Apple promotes the iPod Touch as mobile video games console.

The memory of the iPod’s increased enormously throughout the time. So the first gen Ipod from 2001 had a memory of 5 or 10 GB. The 6.2 version of the classic iPod comes with 120 or 160 GB. And also the other models where improved permanently.

I think the only way that the iPod could become so popular is that apple gives it such an „exclusive“ style. You can only charge your iPod with the iTunes software, only can use Apps from the Apple store, and you even can’t change the batterys yourself. Today the iPod is not just a product, it has become a lifestyle.

There has also built up a whole new market around the iPod. For example you can get docking stations for it, to use it as mobile jukebox. If you are intrested please visit ipod docking stations.

Computer Viruses And Preventive Measures

February 27, 2010 By: lilybird Category: Data Recovery/Security

A computer virus is a computer program that can copy itself and infect a computer. The term “virus” is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.

The term “computer virus” is sometimes used as a catch-all phrase to include all types of malware, adware, and spyware programs that do not have the reproductive ability. Malware includes computer viruses, worms, trojans, most rootkits, spyware, dishonest adware, crimeware, and other malicious and unwanted software, including true viruses. Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself automatically to other computers through networks, while a Trojan is a program that appears harmless but hides malicious functions. Worms and Trojans, like viruses, may harm a computer system’s data or performance. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious and go unnoticed.

Anti-virus software and other preventive measures

One of the best anti-virus software is for example NOD32 antivirus

Many users install anti-virus software that can detect and eliminate known viruses after the computer downloads or runs the executable. There are two common methods that an anti-virus software application uses to detect viruses. The first, and by far the most common method of virus detection is using a list of virus signature definitions. This works by examining the content of the computer’s memory (its RAM, and boot sectors) and the files stored on fixed or removable drives (hard drives, floppy drives), and comparing those files against a database of known virus “signatures”. The disadvantage of this detection method is that users are only protected from viruses that pre-date their last virus definition update. The second method is to use a heuristic algorithm to find viruses based on common behaviors. This method has the ability to detect viruses that anti-virus security firms have yet to create a signature for.

Some anti-virus programs are able to scan opened files in addition to sent and received e-mails ‘on the fly’ in a similar manner. This practice is known as “on-access scanning.” Anti-virus software does not change the underlying capability of host software to transmit viruses. Users must update their software regularly to patch security holes. Anti-virus software also needs to be regularly updated in order to prevent the latest threats.
One may also minimize the damage done by viruses by making regular backups of data (and the operating systems) on different media, that are either kept unconnected to the system (most of the time), read-only or not accessible for other reasons, such as using different file systems. This way, if data is lost through a virus, one can start again using the backup (which should preferably be recent).
If a backup session on optical media like CD and DVD is closed, it becomes read-only and can no longer be affected by a virus (so long as a virus or infected file was not copied onto the CD/DVD). Likewise, an operating system on a bootable CD can be used to start the computer if the installed operating systems become unusable. Backups on removable media must be carefully inspected before restoration. The Gammima virus, for example, propagates via removable flash drives.

This database application is Microsoft Access. If you consider taking the Microsoft Access training, you should think how it might affect you personally as well as your company. Having database development skills among others is a great addition to your resume. And if you also have the spreadsheet skills to compliment the database experience, then you will easily find a good job in out information based world.

But what are the main database skills that are most important to get? A good place to start is to have the knowledge of relational database theory, which includes the information about how one piece of data can be related to another. You will be able to relate the customer to an order or link a student to a class. You will also know if the student can belong to only one class and if the course can be available to one or many students. These examples are used to explain the basis of the theory of relational database.

After you obtain enough knowledge about relational database theory and know how to relate data, you can start creating the databases. You will begin with creating tables for storing your data and then relate the tables together. Once you master this part, you can move on to designing the screens also known as forms, which are used for entering data. You will be able to add controls to your forms and make sure they are easy to use.

By now you have the tables for keeping the data and forms for entering data to the database. Now it is time to learn how to get the data out of the database. You will use queries for extracting data from the database. It might seem tricky for Access beginners, but after a good training course you will easily get a hang of it. Queries are extremely useful in your database, because you can get the needed data quickly without having to look for it manually, checking every table and field. You can set the needed criteria when you run the query and it will give you results very quickly. You can also then use the data from these queries to create a bar chart or a graph.

One more very useful object present in Access database is a report. You are able to present the data in a printed format by creating simple reports after running the query. Microsoft Access also gives you the possibility to link to other MS Office applications. It is a very useful option, which can greatly increase your productivity and save a lot of time.
