DNA is a good source of evidence for forensic experts, for doctors to identify cancer, recently used for SARS detection, to name a few .\n\nThere are techniques which are used to detect the presence of a specific sequence in a given DNA sample. PCR  or Polymerase Chain Reaction is one of them. here we amplyfy a specific sequence of DNA of interest. if the biological sample contains that DNA sequence then its amplified and can be visualized on a electrophoretic gel. DNA being negativey charged runs on an agorose gel under electric current towards the positive electrode and gets separated based on the size...slower the movement the bulkier the fragment. \n\nforensic experts use this to match DNA samples from site of crime to the suspect. this can also be used in case of paternity disputes, to detect the predisposition of a person to cancer etc etc.\n\nthere are many more techniques which you can search

The dual utility of DNA fingerprinting for the prosecution and the defense actually surfaced at its first use in police work. In 1986, two years after the technology was invented by Alec Jeffries of Leicester University in the United Kingdom, a girl was raped and murdered several miles from Jeffries's laboratory. \n\nA suspect confessed to the crimes, but denied a previous, similar crime. A DNA test confirmed that denial -- and when the police DNA-tested evidence from the recent murder, they discovered that the suspect's DNA was similarly absent. The suspect, once confessed but twice innocent, walked free. With both crimes now unsolved, the police found a pretext to collect blood from local men and eventually found and nailed a man whose DNA appeared at both crime scenes. "It was an extraordinarily auspicious beginning...," wrote Harlan Levy, a former New York City prosecutor. "In its first known application to a murder case, DNA testing fulfilled both its promises, clearing an innocent man and helping convict a guilty one." \n\nDNA fingerprinting was a whole lot less decisive in the O.J. Simpson case: The ex-footballer walked on double murder charges, even though his blood was found in compromising situations. The jury decided that the DNA evidence was tainted by police misconduct. While the DNA was neither convincing nor convicting, the Simpson trial forever changed the legal treatment of DNA: \n\nThe procedures for collecting and processing DNA have been tightened. With the tests considered unassailable, proper handling of evidence is crucial. \n\nJudges and juries know the basic science of testing -- or at least accept its scientific validity. George Gaucys, HLA/paternity laboratory manager at the American Red Cross in Madison, Wis., says, "There's less need to testify," in the 700 or so paternity cases his lab handles each year. (DNA fingerprinting is used to prove paternity so states can prod fathers to fund their children's upbringing.) \n \nDNA fingerprinting and the databases needed to take maximum legal advantage of them do raise privacy and ethical concerns. Some observers fear any misuse of the FBI's national DNA database, the Combined DNA Index System (CODIS). "These are technologies in which powerful organs in society control members with less power," Philip Bereano, a director of the American Civil Liberties Union, told Time in 1999 (see "DNA Detectives" in the bibliography). "They are inherently violative of civil rights." CODIS went online in 1998, offering access to state data on DNA related to rape, murder and child abuse. \n\nAnd that's fine with prosecutors, who note that given the difficulty of preventing repeat crimes by sex offenders, and the gravity of rape and murder, databases are the fastest, best protection for the public. \n\nBeyond political and legal acceptance, the increasing use of DNA fingerprinting reflects the introduction of a faster, cheaper and better technique that can produce a conviction from a pin-head size drop of blood. In fact, even a few skin cells may do the trick. Says Laber, "We've had good luck with cigarette butts, stamps, envelopes, ski masks, even a hat band. If you lose a hat or an article of clothing, there's a reasonable chance" your skin cells may be found on it.

The main advantage of a network is that computers can share information.  A computer network can store more data than a stand-alone computer.  This is great if you have a business because your employees can exchange vital information easier.\n\nThe main disadvantage would be security concerns, i.e. someone hacking into your network.  However, you can buy software and hardware to help prevent this.  Just remember that any protection you get can be broken if the hacker has enough time and patience.

We all know the disadvantages are death, misery,repression, fright, bodily injuries, rampages, evilness.\nThe advantages would be population control, improved economy for many, advances in technology, employment, nationalism( may unite people who have a common enemy), education about other societies, spreading of ideas.

The advantage is obviously getting access to info on criminal activity that would otherwise not be available but the downside is the immunity that so often is traded for the info provided by these informants.  Sometimes it's too big a price to pay.

The advantage is knowledge, disadvantage is time lost from enjoying life because there is much more to life than setting in front of a computer.

The biggest disadvantage is all the work a file system creates. Without any file system, you couldn't put software on your computer, or store any files. This would mean that programmers, technicians, and various other IT people would have a lot less to do.

Actually you are on to something.  Forensics as an academic field of study is actually relatively new.  In many of the sub-disciplines one starts with a general major (IT) and then gradually becomes more specialized.  What frustrates many of us in academia is that (1) the original model of forensics appears to have been one of specialists - PhD/Professional degree required.  Now kids are under the impression thanks to TV shows that you can get in with an undergraduate degree!  (2) Because of this misconception, quite a few places are trying to accomodate it!  This drives some faculty crazy, but I come from an interdisciplinary perspective and think it's a great opportunity for students to view things more holistic perspective.\n\nThe grad school issue won't be going away, however.  In fact, with so many students brainwashed by the tube into thinking there must be detective jobs all over the place, you now have LOTS of competition and in the academic marketplace (outside of troubling state regulations) that means two things: increasing GPA requirements and higher degree levels to attain to get the job.  Be prepared to work hard to beat the competition to the best spots!

less elements, so less complicated maths.  \n\nYou get a less accurate result, which I don't consider an advantage.

The advantage is it's free.\n\nThe disadvantage is that is very unsophisticated and gives you very little control as what to allow in or out.\n\nZone Alarm is a much better choice.

--good--\n-easy body identification if it's damaged beyond recognition in an accident of if some psycho-killer finds ye alone in an alley.\n-not having to carry y'wallet on ye, makes it harder to rob a person.\n\n--bad--\n-theft, instead of stealing one's wallet, will adapt to include the theft of limbs, instead.\n-the way static electricity haunts me, the chip would probably explode the first time i tried to tough the metal doorknob.  hahah!\n-certain of the more psychotic factions of You Know What would start screaming "mark of the beast!" and probably revolt.

"If performed correctly, DNA testing becomes a powerful and impartial tool, able to correctly identify any perpetrator in crimes where there is relevant biological evidence. As the technology advances and is applied in appropriate cases before trial, the chances of convicting an innocent person, at least where identity can be proven through biological evidence, is greatly diminished."

Check out the web links below. I think the answers to your questions are there.\n\nForensic science technicians investigate crimes by collecting and analyzing physical evidence. Often, they specialize in areas such as DNA analysis or firearm examination, performing tests on weapons or on substances such as fiber, glass, hair, tissue, and body fluids to determine their significance to the investigation. Proper collection and storage methods are important to protect the evidence. Forensic science technicians also prepare reports to document their findings and the laboratory techniques used, and they may provide information and expert opinion to investigators. When criminal cases come to trial, forensic science technicians often give testimony, as expert witnesses, on specific laboratory findings by identifying and classifying substances, materials, and other evidence collected at the scene of a crime. Some forensic science technicians work closely with other experts or technicians. For example, a forensic science technician may consult either a medical expert about the exact time and cause of a death or a technician who specializes in DNA typing in hopes of matching a DNA type to a suspect.
