Some Computer Forensics BasicsWritten by Allen Butler
- Computer Forensics in a Nutshell Computer forensics are examinations of computers made during a criminal investigation. When police look into files and data on a computer during an investigation, they are using computer forensics. It is obvious that you would want to look at a suspect's computer if they are involved in a hacking or industrial espionage case where computer is being actively used to commit crime, but these are not only sorts of cases where computer forensics is used. Even if a murder case or a theft where a suspect used a computer could have information on it that is important to case. You never know where you might find information that you need for a case, and so investigators look at everything they can find. - What Computer Forensics Investigators Look At There are three basic kinds of data that a computer forensics investigator will look at when examining a computer: saved data, meta data and deleted data. The first thing that a computer forensics investigator will do before examining this data is to make a copy of hard drive. Even just looking at a file can sometimes change data or meta data, and it is important that none of original information is tampered with when using it in a criminal investigation. Making a copy of computer's hard drive allows investigator to go through all of data without having to worry that he is tampering with potential evidence. Saved data is any data that is normally accessible on a hard drive. It is all data that is saved onto hard drive. This includes things like documents, imagages, internet logs, program files, etc. This is easiest data to look at, because it involves no special working to access these files. Sometimes files might be hidden within multiple folders or using confusing file names, so examination will need to be thorough to make sure anything important to case is found. Files can also sometimes be password protected, which makes it more difficult for an investigator to open them to read them. Computer forensics investigators are trained to get around these kinds of blocks. Meta data is information that accompanies saved data. It is information that tells you about saved dat, like when a file was created, when it was last modified and when it was last accessed. This tells us when something was made, when person who created file was using it and if he had made any changes to it. This can be useful as it can help put a timeline to data investigator is looking at, and match up information for use with case.
Save Money and the Environment with Xerox Phaser Solid Ink PrintersWritten by Allen Butler
Xerox line of Phaser printers are among best printers available for office printing solutions. With great prices they are most affordable printers in their class. You can purchase a Xerox printer for only a little more than you would pay for many black-only printers. Previous printers in this line had used Laser technology, they have now upgraded to using solid ink. Solid ink unlike liquid ink allows for one pass printing that is as fast as a laser printer along with being same quality. Because you can easily refill ink without having to purchase entire new cartridges in order to print, it saves you money not only in purchasing printer but in keeping it filled with ink to keep on printing your office documents.
With solid ink, you can just replace ink without having to purchase entire new cartridges, saving you time and money as well as being better for environment. Ink is stored in solid sticks rather than liquid which must be contained inside of a disposable cartridge, so there is no extra waste. Our landfills are being filled with computer cartridges and carriers that must be disposed of. If you care about environment and everybody does, using solid ink is a way for you and your company to not only save money but do something good for environment as well.
When you get your replacement ink, you simply slip your new color stick into built in cartridge in machine, and ink will be taken from stick as it is being printed. This provides for easy reloading of your printer apparatus, and also removes mess associated with liquid ink cartridges. Solid ink can never spill or leak because it is in a solid form. You can do it in seconds on fly without having to ever worry. And there are no problems if ink starts to get low, unlike liquid ink solid ink prints just as high quality documents when it is almost out of ink as it does when it is full, so you can keep on printing until ink is completely gone.
