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.

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.

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.

Parts of a Digital Camera
Parts of a Digital Camera
Although the major parts of the digital camera is much the
same as the typical film camera, there are differences that
may confuse people especially those who are making the jump
from the film to digital format.
It doesn’t also help that digital cameras, even the most
basic ones, typically have more buttons than the usual
point and click film cameras. We hope that with this
article, we can help you in identifying the parts of your
digital camera.
1. The LCD screen
– this is probably the most obvious difference between a
digital and a film camera. The LCD screen provides users
with a preview of the shot they will be taking.
Unlike film cameras which use only the viewfinder, the LCD
gives people exactly what they see on the display. Aside
from that, the LCD also provides information on the camera
such as the amount of battery left and the like.
2. A slot for the storage media
– while the film in a film camera is usually loaded on the
back, the slot of the storage media differs from one type
of digital camera to the other.
The user manual can help you find where it is.
3. A slot for transferring your data
– you can transfer that pictures you have taken by
physically removing your card from the camera and putting
it into the card reader of your computer.
However, you can also connect your camera via USB or other
ports on your computer if you do not have a card reader.
Apple Computers
Apple Computers
In 1976, three enterprising young men founded Apple Computers, Inc, with the intention of creating and distributing personal computers. Steve Jobs, Steve Wozniak, and Ronald Wayne began with a dream of making super computers smaller and available to the public. They built their computers in Jobs’ parent’s garage and debuted the Apple I personal computer kit the year they founded Apple. Eventually, 200 of these computers would be built.
Jobs approached a local computer store, The Byte Shop, which ordered fifty units and paid 0 for each unit after much persuasion from Jobs. Jobs then ordered components from Cramer Electronics, a national electronic parts distributor. Using a variety of methods, including borrowing space from friends and family and selling various items including a Volkswagen Type 2 bus, Jobs managed to secure the parts needed while Wozniak and Ronald Wayne assembled the Apple I.
In 1977, the Apple II was introduced and quickly became much more popular than its competitors, the TRS-80 and the Commodore even though the price of the Apple was higher. One of the big advantages of the Apple was the development of the floppy disk drive and software.
The Apple II was chosen by programmers to be the desktop platform for the first “killer app” of the business world. This was a spreadsheet program called VisCalc. This created a market for the Apple. The corporate market attracted many more software and hardware developers to the machine plus it attracted home users in an effort to be compatible with their business machine.
Over the years, the Apple computer would release many more designs each one just a little better than the last. In 1989, Apple introduced the Macintosh Portable. However, this computer was actually quite bulky and cumbersome and was met with mixed reviews. At this point, Apple hired industrial designers to develop a better, more portable personal computer.
In 1991, the Apple Power Book was introduced. The Power Book would provide the layout and form for the laptop computers we know today. This solidified Apple’s reputation as a quality manufacturer of both desktop and portable machines. The success of this laptop led to increased revenues and growing popularity of Apple in the computer market.
While they have had their ups and downs over the years, Apple Computers, Inc. has remained a solid presence in the computer and laptop market. Their products have continued to evolve to meet the needs of both the corporate and individual user.
