Motherboard
The motherboard is the "brain"of the computer. Components directly attached to the motherboard include:
The central processing unit (CPU) performs most of the calculations which enable a computer to function, and is sometimes referred to as the "brain" of the computer. It is usually cooled by a heat sink and fan.
The chipset mediates communication between the CPU and the other components of the system, including main memory.
RAM Stores all running processes (applications) and the current running OS. RAM Stands for Random Access Memory
The BIOS includes boot firmware and power management. The Basic Input Output System tasks are handled by operating system drivers.
Internal Buses connect the CPU to various internal components and to expansion cards for graphics and sound.

Google Earth

Google Earth is a virtual globe, map and geographic information program that was originally called Earth Viewer, and was created by Keyhole, Inc, a company acquired by Google in 2004. It maps the Earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. It is available under three different licenses: Google Earth, a free version with limited functionality; Google Earth Plus (discontinued), which included additional features; and Google Earth Pro ($495 per year), which is intended for commercial use.

The product, re-released as Google Earth in 2005, is currently available for use on personal computers running Windows 2000 and above, Mac OS X 10.3.9 and above, Linux Kernel: 2.4 or later (released on June 12, 2006), and FreeBSD. Google Earth is also available as a browser plugin (released on June 2, 2008) for Firefox 3[4], Safari 3, IE6 and IE7. It was also made available on the iPhone OS on October 27, 2008, as a free download from the App Store. In addition to releasing an updated Keyhole based client, Google also added the imagery from the Earth database to their web based mapping software. The release of Google Earth in June 2005 to the public caused a more than tenfold increase in media coverage on virtual globes between 2005 and 2006, driving public interest in geospatial technologies and applications.

RAID
RAID is an acronym first defined by David A. Patterson, Garth A. Gibson and Randy Katz at the University of California, Berkeley in 1987 to describe a redundant array of inexpensive disks,[1] a technology that allowed computer users to achieve high levels of storage reliability from low-cost and less reliable PC-class disk-drive components, via the technique of arranging the devices into arrays for redundancy.
More recently, marketers representing industry RAID manufacturers reinvented the term to describe a redundant array of independent disks as a means of disassociating a "low cost" expectation from RAID technology.
"RAID" is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple hard disk drives. The different schemes/architectures are named by the word RAID followed by a number, as in RAID 0, RAID 1, etc. RAID's various designs involve two key design goals: increased data reliability or increased input/output performance. When multiple physical disks are set up to use RAID technology, they are said to be in a RAID array. This array distributes data across multiple disks, but the array is seen by the computer user and operating system as one single disk. RAID can be set up to serve several different purposes.

What Is The Department of Justice Doing About Internet Fraud?

Since February 1999, when the Department of Justice established its Internet Fraud Initiative, the federal government has been expanding its efforts to combine criminal prosecution with coordinated analysis and investigation as part of a comprehensive approach to combating Internet fraud.

Prosecution

The Justice Department has begun to bring a number of criminal prosecutions throughout the country against individuals and groups engaging in various types of Internet fraud. Here are some examples of federal criminal prosecutions directed at Internet fraud:
  • Auction and Retail Schemes Online

1. Oxford, Mississippi On August 27, 1998, a woman was sentenced in the Northern District of Mississippi to 15 months' imprisonment and $9,432 restitution on fraud charges relating to her conduct of a fraudulent scheme. The scheme involved her use of Web pages and interactive computer locations on the Internet for falsely advertising various computer hardware and software and computer accessories.

2. Philadelphia On March 2, 2000, three men were criminally charged in the Eastern District of Pennsylvania for their alleged roles in falsely offering the sale of Beanie Babies® on the Internet, and then failing to deliver the orders or sending stolen Beanie Babies® that generally were of substantially less value than the items ordered.


3. San Diego On March 6, 2000, a man pleaded guilty in the Southern District of California to mail and wire fraud in connection with his conduct of a fraudulent scheme involving Internet sales of Beanie Babies® that he never delivered.

4. Santa Ana, California On November 1, 1999, a man was sentenced in the Central District of California on mail and credit-card fraud charges to 14 months' imprisonment and $36,000 restitution, for his conduct of an Internet auction fraud that falsely offered digital cameras and laptop computers to consumers.

6. West Palm Beach, Florida On February 12, 1999, a man was sentenced in the Southern District of Florida on wire fraud charges to six months home detention and more than $22,000 restitution, for his conduct of a fraudulent scheme in which he falsely advertised on Internet auction and retail sale Web sites computer components that he purported to have for sale, but did not have or obtain most of the merchandise he advertised.

  • Business-Opportunity Schemes Online


1. Los Angeles In November, 1999, four individuals were criminally charged in the Central District of California for their roles in conducting a fraudulent scheme, in which they sent out approximately 50 million e-mails that falsely advertised work-at-home opportunities for people but provided few actual opportunities for people who paid the $35 advance fee.

  • Investment Schemes Online "Pump-and-dump" schemes, short-selling schemes, Ponzi schemes, and other fraudulent investment schemes have all been subjects of federal prosecution throughout the country.
    1. Alexandria, Virginia In September 1997, a man was sentenced in the Eastern District of Virginia to one year's imprisonment and fined $20,000 on securities fraud conspiracy charges relating to his touting of a stock involved in a "pump and dump" scheme.

    3. Charlotte, North Carolina In 1999, two individuals pleaded guilty in the Western District of North Carolina to securities fraud charges for their roles in offering securities in a nonexistent investment bank that purportedly offered, among other things, a "guaranteed" 20 percent return on savings.
    4. Cleveland On March 22, 2000, four people were indicted in the Northern District of Ohio, on charges including conspiracy to commit and committing mail and wire fraud. The defendants allegedly devised and carried out a scheme to defraud "investors" in a "Ponzi" pyramid scheme.

    5. Los Angeles On January 4, 2000, two men were indicted in the Central District of California on securities fraud charges for their alleged roles in the NEI Webworld scheme described earlier. In addition, on August 30, 1999, the individual who conducted the PairGain Technologies scheme mentioned earlier was sentenced in the Central District of California to five months' home detention and $93,000 restitution.
    6. New York On August 9, 1999, a man was criminally charged in the Southern District of New York with securities fraud.

Credit Card Fraud

1. Ft. Lauderdale In November, 1997, a former graduate student was sentenced in the Southern District of Florida on wire fraud charges to four months' home detention, for a scheme in which he obtained the names of multiple students from a local university and fraudulently applied for 174 credit cards via the Internet. Because of the quick investigative work by the Postal Inspection Service, no losses were incurred.

2. Wilmington, Delaware In 2000, three individuals were indicted in the District of Delaware on charges of conspiracy, bank fraud, identity theft, Social Security fraud, and wire fraud, for their alleged roles in the military officers' Social Security number/credit-card fraud scheme described earlier.


Other Types of Internet Fraud


1. Los Angeles On February 7, 2000, a man was sentenced to 87 months' imprisonment for his role in a scheme that purported to provide immigration assistance to aliens seeking to become residents or citizens of the United States. Using Web sites, newspaper advertisements, recruiters, and word of mouth to offer their services to aliens, the leaders of the scheme typically charged more than $10,000 per client and promised that the client would receive particular immigration documents. In some cases, however, the leaders of the scheme provided their clients with counterfeit or false immigration documents; in other cases, they provided no documents at all, and blamed the government and the legal system for the delay in providing the promised documents.

2. Los Angeles In November, 1999, four men were criminally charged in the Central District of California for their alleged roles in conducting the "work-at-home" scheme described earlier.

TIPS ON SPECIFIC INTERNET FRAUD SCHEMES -
AUCTION AND RETAIL SALES SCHEMES

To reduce the chances that you may be victimized by fraudulent online auction or retail sales schemes, here are two basic tips:

Research The Prospective Seller Carefully.
If you haven't had personal (and favorable) experience with someone who's offering certain goods for online sale or auction, look for sources of information at the Web site where the offeror's information is posted, and at other Web sites. Some online auction sites provide their member with opportunities to provide "feedback" on their experiences with particular sellers (although certain sellers have tried to manipulate the "feedback" process by posting favorable but false reports about themselves).

Pay by Credit Card or Escrow Service If Possible.
If you charge your online purchase on a major U.S. bank-issued credit card, your liability may be limited to $50 under any circumstances, and at least one credit-card issuer has recently indicated that it will waive the $50 deductible. In the alternative, some online auction Web sites offer escrow services that (for a small percentage) will guarantee delivery of the ordered goods before releasing your payment to the seller.


INVESTMENT SCHEMES ONLINE
To reduce your risks from online investment opportunities that may be fraudulent, here are four basic tips:

A) Take Your Time In Making Investment Decisions.
Remember that in any "get-rich-quick" scheme, there's only one person who's guaranteed to get rich quick: the person promoting the scheme.

1) If you're thinking about pursuing some online investment opportunity, start by recognizing that you need to take your time in making decisions about what you do with your hard-earned money. Sound investing for the long term takes patience, the will to ignore momentary market fluctuations, and a carefully thought-out plan for reaching your investment goals.

2) Whether you're researching an investment opportunity on the Web, or talking with a broker or someone else who's offering you the opportunity, you should make it a habit to take notes of what you're reading or hearing. The North American Securities Administrators Association (NASAA) publishes an investor's notepad entitled, "When Your Broker Calls, Take Notes!" The forms are printed in notepad fashion so investors can get into the habit of making written records of their conversations with their brokers. The notepad is available from your state securities regulators or on the NASAA website at http://www.usdoj.gov/cgi-bin/outside.cgi?http://www.nasaa.org/whoweare/media/Notepad/html.

B) Research The Potential Investment Opportunity - And Who's Behind It - Carefully.
If you're making a major investment decision, here's an easy rule of thumb:
Count how many weeks, months, or years it took you to earn that amount of money, and then resolve to spend at least that many days to research the investment opportunity and the people who are promoting or running it.
Several agencies and self-regulatory organizations can give you a substantial hand with your research, at no cost to you:

1) The SEC's Web site, http://www.sec.gov/, contains a wealth of information about many companies, in at least two principal sources: (1) reports these companies file electronically through the EDGAR system; and (2) the SEC Enforcement Division's online files, which among other things list the persons against whom the SEC has filed civil enforcement actions for securities law violations (and, in some cases, against whom the Department of Justice or state or local prosecutors have filed criminal charges). You can use the built-in search engine at the SEC's Web site to check out names, and see whether you get any hits in the SEC enforcement action listings. The site also contains some excellent lists of questions to ask about any investment opportunity, and a discussion of how to spot signs of online investment scams.

2) The Federal Trade Commission's Web site, http://www.ftc.gov/, also has an internal search engine, which allows you to look for information on particular individuals or companies involved with your prospective investment, including listings of FTC enforcement actions.

3) The National Association of Securities Dealers (NASD) allows you to check for some disciplinary history on the broker or company that's touting a particular investment. Go to http://www.usdoj.gov/cgi-bin/outside.cgi?http://www.nasdr.com or call the NASD's Public Disclosure hotline at 800-289-9999.

4) State securities regulators in your state may also have information on the company or its organizers that you can obtain. Check your local telephone listings for the securities regulator in your state, or go to the North American Securities Administrators Association's Web site, http://www.usdoj.gov/cgi-bin/outside.cgi?http://www.nasaa.org, for a listing of state and provincial securities regulators in the United States, Canada, and Mexico.

5) If the potential investment involves commodities, you may also need to check out the Commodity Futures Trading Commission's Web site, http://www.cftc.gov/, and use its internal search engine to check out companies and people. The National Futures Association can also give you information on the disciplinary history of brokers or other commodity professionals, the registration status of firms and individuals, and arbitration and mediation procedures. Call them at 1-800-676-4NFA between 8:00 a.m. and 5:00 p.m. Central Time or go to http://www.usdoj.gov/cgi-bin/outside.cgi?http://www.nfa.futures.org.

6) If the prospective investment supposedly involves an Internet financial institution, go to the Federal Deposit Insurance Corporation (FDIC)'s Online Banks Web pages, and use the FDIC's Financial Institutions Search Engine you find there to see whether the financial institution has a legitimate banking charter and is a member of the FDIC.

7) When the potential investment is based outside the United States, remember that your money may be even more at risk, as you may have little or no recourse in the event of loss. The United Kingdom's Financial Services Authority allows investors to check out U.K. and European Union-based investment offers at its Central Register (call 01-71-929-3652).

8) Finally, use one or more of the many Internet search engines - like the ones available on your Web browser - to help you expand your research on the company's background and market performance.

If you use these resources, and find that one or more of the people behind your prospective investment has been subject to legal action, especially for investment offers, it's a very safe bet that the investment is a high risk at best and an outright scam at worst.


C) Boilers and "Boiler Rooms" Need High Pressure To Do Their Jobs. If someone online is insisting that you invest right away, or telling you that someone else will get the "deal of a lifetime" if you wait, ask yourself at that moment whether you're feeling pressured and uncomfortable. If you are, that's a major red flag warning you away from the investment.

1) Legitimate businesspeople and brokers don't need to subject you to "high-pressure" tactics to make you commit to an investment decision before you're ready. That's why the operations scam artists run are called "boiler rooms": like steam boilers, high pressure is what they're designed to generate (along with a wide array of lies, half-truths, and deceptive statements).

2) Even if you're in a chat room or online discussion group where everyone seems to be "just like you," enthusiastic about investing and looking for the next great investment, not everyone who's online at that moment is necessarily just like you. Some of the messages you see may be coming from someone working for the investment scheme's organizers - or even one of the organizers himself - who pretends to be someone else, so they can pressure you in less obvious ways and get you to fall for the scheme.

D) Check Out The Competition. If someone's promising you returns on investment that are far above what you see in the financial pages of your newspaper or at your local bank, ask yourself how they can possibly guarantee those fabulous returns.

1)Sometimes it's because, as in any good old-fashioned Ponzi scheme, they're paying older investors with money that newer investors gave them, and they're trying to string out the fraud to rope in as many investors as possible. Sometimes it's because they'll promise you anything, but give you nothing once you've entrusted your money to them.

2) If, after you've gone through all of the steps listed above, you still feel like the prospective investment is worth considering, talk to a broker, financial adviser, or banker with whom you've done business for a while, and ask whether his or her firm or financial institution can offer you a comparable type of investment with less risk.
a) The chances are that they'll say no, but they'll be willing to take time with you to walk through the information you have about the prospective investment and point out the risks you may be taking, as well as possible alternative investments that offer more realistic returns.

b)You lose nothing by consulting an investment professional about any major investment decision - and you stand to lose a lot if you don't.
