What Remains to be Today’s Computer Forensics Problem?
What Remains to be Today’s Computer Forensics Problem?
Computer forensics is one the fields today which often gets updated. Many agencies have found the application of computer forensics very useful especially in the investigation of fraudulent actions and crimes. More so, computer forensics is the procedure that is applied when electronic devices such as the computer media is placed under careful investigation.
The process involves the discovery and analysis of any available data whether they have been hidden or deleted. These are among the evidences that will support the defense and claim of a particular individual or company as they file for any legal action.
Moreover, computer forensics specialists use the tools that recover both the accidentally and intentionally erased files and information. So whether the loss of the data is blamed to the untoward occurrences of hardware failure, there is a better chance of recuperating them. One of the biggest computer forensics problems though is how to retain the original data without the slightest alteration in them.
So much to say, even during the process of shutting down the computer system to transfer the data into another media may cause changes in them. It is important that the computer forensics expert has the skill to maintain the exact form of the data. Nobody can exactly say when the data may be altered but with the most apt tool and the specialist’s skills, it can be possibly prevented.
Computer forensics attracted the attention of the public during the height of the Enron scandal which prompted the widest-ranging computer forensics investigation marked in the world’s history. As computers these days are becoming an integral part of human life, big quantities of data are being stored in these electronic devices.
More so, crimes and other fraudulent acts are likewise increasing in intervals. Computer forensics investigations are also done in emails, websites visited, chat histories, and many other forms of electronic communications.
The advances in today’s technology have shaped the improvement of computer forensics. The developers continually upgrade their tools to meet the increasing intensities of computer forensics problems. Modern software and tools are coming out into the market which nonetheless makes the task easier for the computer forensics experts. Thus, data is found and restored faster and with more preciseness.
These evidences need to be in their original format especially when they are to be used as evidences in the court. These proofs are often gathered from all kinds of computer media such as the discs, Pen drives, tapes, memory sticks, logs, emails, PDAs, handhelds, deleted information, and hidden documents.
The people’s common notion is that when the data is deleted from its location, the file is already completely deleted and unfound. This makes you wrong though. Upon deletion, what is erased is only that of the data’s reference location but the actual document remains intact in your computer system.
It is easiest to tell that the data have been deleted but the common computer forensics problem is where and how to find it and how to recover them without making traces of changes. Thus, the solution to the dilemma will entirely depend on the computer forensics professional’s skills.
Computer data security is very important so it is also significant that they remain original. Part of the training of these professionals includes the molding of their skills to be careful when handling the recovery of the data at all times.
However, it is not for them to conclude when data may be altered or not. This remains as one of the top computer forensics problems to date.

Things To Do When Your Computer Starts Developing Problems
Things To Do When Your Computer Starts Developing Problems
The introduction of the lap top has made computers portable and you can find them on planes, trains, buses and in cars. Computers are the latest method of communicating with nearly everyone, everywhere. That is until they start to develop problems. They are notorious for breaking down a few hours before you have to turn in your paper or make your office presentation.
Most computers have warranties covering service. There is usually probably a service where computer owners can get help over the phone or online. This service is essential to computer owners. If you have tried everything you know to resolve a computer problem and nothing is working, you can go online, at the computer manufacturer’s site, and do some simple diagnostic tests. Usually the site contains questions that commonly arise when computers fail. Simple solutions, from plugging in the equipment to rebooting a program, are available online.
If the online suggestions don’t work, you can call a service over the phone. The cable or phone company provider has this service available when you first are hooked-up to the Internet. A computer technician will listen to your complaint and then offer a variety of solutions. A pleasant, knowledgeable voice on the other end of the line can calm you down when you’re ready to pull your hair out or commit violent acts against your computer.
Sometimes, the phone technician can’t fix your problem. Then you need to call a repair service. There are companies that will dispatch computer technicians who will come to your home and, for a price, fix whatever is ailing your computer. Geek Squad is one such service. It will, on a 24/7 basis, provide upgrades, repairs and protection from spyware and viruses. If you think the problem is something you did as a result of not being familiar with a computer system, Geek Squad offers one- and two-hour personal instruction courses.
After it has been established that you don’t have a software problem, you now face the challenge of correcting a hardware problem. Then you have no choice but to open up the computer and do the repairs yourself. While most of us would pass on this option, it is not as difficult as it seems. There are less than 12 parts, including keyboard and mouse, in most computers. The number one cause of computer malfunctions is the AC power supply. Often, especially in cheaper models, replacing it solves all the problems.
There are some problems that you cannot solve without proper training, such as repairing the motherboard or the CPU or fixing video components and defective hard drives. Then you have to take your computer to a repair facility. There they can take your computer apart, run a diagnostic checkup and replace what needs to be replaced. They can install new hard drives, new components and programs, and replace any mechanical parts that are not working properly. They will also clean the inside of your computer, where dust and other smart particles have collected. If your computer is under warranty, you will probably get these services for free. If you have not purchased an extended warranty, you will have to pay for whatever is done.
If there is a hardware problem with your computer, you may not have to take it to the store where you bought it or a repair facility. There are facilities that come to you and, like Geek Squad, repair the malfunctioning equipment in your home.
How to Choose The Right Computer
How to Choose The Right Computer
How To Choose:
There are only a few main parts of the computer that truly make the difference between the others. As long as when you are looking for the right computer to buy, you pay attention to these parts and see what they are, and how fast they are, you will end up with the computer system you really want and need, instead of another computer that you will be looking at upgrading in the near future.
The Processor:
All computers only understand 1’s and 0’s which is the binary language. The processor does the calculations with these 1’s and 0’s to give you your windows, icons, folders, text, pictures, etc.. The faster your processor’s speed is, the faster it can do these calculations, the less wait time or “lag” you will have. Now that doesn’t mean that you have to get the latest and greatest of processors out. It just means that you have to make a decision based on understanding what that number next to the GHz means.
If you are a student or you are going to be using this computer for such purposes as: research, surfing the web, playing card games, word processing, book keeping, or anything of the like, it is recommended that you get a processor that is accommodating for these activities. You definitely do not need anything super fast, but you do not want to get too low end either, otherwise you will be left in the technological dust when the new processors come out and everyone you know upgrades. Typically a 2.6Ghz processor is as low end as you want to go, but with the new (M)obile technology that laptops have out this number changes. If you see “Mobile” or a “M” anywhere in the processor area when you are looking at a laptop, the low end in this case is around 1.7GHz.
If you are a gamer or a power user on the computer, or plan on being one, you will want to go with something a bit more powerful. Recommendation is definitely something over 3.0Ghz or 2.0Ghz(Mobile Technology) as a low end. If you are a gamer or power user you will want to be in a high end computer to best utilize the speed capabilities of your programs and games. This too does not necessarily mean you need the latest and greatest processor out there, but you do want something that will give you the power you need without killing your wallet, but also not leaving you having to upgrade as soon as the newest games or high-end programs come out. A good rule of thumb is to look around and compare a few different computer systems, and look for the best speed you can find, just before the price jumps up some crazy amount just for another 0.2 or 0.4Ghz.
Memory:
What is memory anyways? RAM or Random Access Memory is a type of computer storage where the content can be accessed in any order. It is primarily used in computer systems to hold information that you or your computer are actively using or actively changing. When you run a program or a game, all the information about that program or game are loaded into memory, but only certain parts of it are needed at a time. The computer sorts through the memory and pulls out this information as needed. The more memory you have to work with, the better off you are. Most companies now a days recommend a minimum of 256mb. This is only if you are on an extremely tight budget. The minimum of today is 512mb of memory, but it is recommended to get 1GB. Not being able to run a program or a game due to not enough memory, is one of the greatest heart breakers. Memory is fairly cheap in today’s computer market, so it is not worth going the cheap route in this area just to come up short later.
Hard Drive:
No matter what you have heard, you can never have enough hard drive space. A few years ago people would laugh when someone bought a 1GB hard drive, saying that they would never be able to fill that in a lifetime. Then people started getting 10, 20, even 40GB hard drives, thinking the same thing, they will never be able to fill up that much space. Well let’s face it, when it comes to our loved ones pictures, and our favorite songs, or videos, we as humans are packrats when it comes to storing things on the computer. We have the ability to burn things off on CD or even DVD now, but we want our “favorites” to be easily accessible. The computer itself uses some of this hard drive space to be able to function, with what is known as a swap file. Your computer will claim a section of your hard drive to use as “virtual memory” so it can access all your commonly used information faster than just your memory(RAM) alone. When choosing the size of your hard drive, remember this, because you will need enough storage space for all your programs, all your music, movies, games, pictures, plus the amount that your computer uses automatically. Make sure that you pay attention to the “rpm” of the drive or rotations per minute. This is how fast the information is read from the hard drive or written to the hard drive. This speed is generally either 5400, 7200, or 10000. The faster the rpm speed the better, but choose this speed based on how you are going to use your computer. If you are using the computer for games, video editing, or 3D modeling, you definitely want your hard drive to be as fast as possible.
Video Graphics:
The graphics capabilities of your computer is a very important factor to take into consideration, especially if you are to be doing gaming, 3D modeling, or video editing. All graphic cards have memory of their own, which enable them to process video graphics and render them to the screen as fast as possible, without slowing your computer system down by using some of its precious memory. Most computers today from major manufacturers have built in graphics cards. These can be upgraded if your needs call for it, but unless you are doing something that requires a major amount of video graphic capabilities, 64-128MB of graphic memory should be an ample amount. For the extreme gamers and 3D artists out there, it is recommended that you get nothing less than 256MB of video memory for optimal performance.
