Vampire adapter Causes

28 Feb

As we know in the average U.S. home, 25 percent of electricity (such as laptop ac power adapter)use by home electronics occurs while the products are off . Is this power used for anything? Do electronics manufacturers hate the environment?

Vampire power causes usually include one of the following:

The gadget, such as pa 10 ac adapter, constantly supplies a charge, even if the batteries are fully charged or if nothing is plugged into it. Many AC adapters, nicknamed wall warts by some critics, waste as much as 50 percent of the power they use
The gadget uses electricity to power a display screen, an external time display or an internal clock. In some cases, this power usage is justified. For instance, your refrigerator needs to monitor temperature levels in order to power up at appropriate times. When it comes to your radio however, it’s not as easy to justify a constant power drain to keep the digital clock lit.
The gadget never fully shuts down so that it’s ready to use at a moment’s notice. Many printers spend hours in standby mode, waiting to receive signals from connected computers. Before you even pick up your remote control, the TV is already using electricity to power the sensor that will receive the signal.

Vampire power has been on the rise during the past decade, thanks to the proliferation of rechargeable gadgets, computer networks and devices with standby power functions. The United States consumes 26 percent of the world’s energy. Of that energy, approximately 5 percent is vampire power . To put that in perspective, that’s between 200 and 400 terawatt hours — roughly as much electricity as the entire country of Italy consumes in a year.

All this energy use enacts quite a hefty toll on the environment. Coal-burning power plants produce carbon dioxide, a leading cause of global climate change. Therefore, less vampire power translates to lower carbon emissions. Even plants that run on nuclear or hydroelectric power produce emissions that can lead to smog and acid rain.

This way is also use to laptop batteries .Want to know how to help the environment and save a little money on your power bill in the process? Pick up a few vampire-fighting tactics on the next page.

How To Avoid The 7 Most Costly Mistakes Of Upgrading Your Network To Optical Fiber – Part 1

26 Feb

Mistake #1: Throwing the Baby out with the Bathwater

Even if they accept the argument that fiber is the way to future proof their network, too many managers see migration to fiber as an all-or-nothing proposition. That is an expensive strategy. In fact, the cost of a massive upgrade is the main reason so many companies are going with the “nothing” strategy and are still installing Category 5E, Category 6 or looking at Category 7 cable. The common complaint is that, while they see the advantage of going to fiber, they simply cannot do a forklift upgrade or throw out so many miles of installed copper.

So what’s the problem? Do the upgrade on the installment plan, a department at a time. There is no reason to toss the installed copper base along with all of its associated electronics. Keep it in place, let it do its job, and plan to keep downgrading the importance of the copper plant as technology advances. Meantime, install optical fiber each and every time the network has to be upgraded. Simply link the copper cable with the fiber cable (using media conversion technology) and rest assured that those on the network are enjoying the best and fastest networking available without worrying about a call from the financial department about wasting money.

Before the advent of media conversion, this was a bigger deal. However, in the past couple of years many people who are upgrading to high speed backbones have discovered that media converters work, work well and work cheaply. Since humans began using machinery, they have been adapting one thing to another. Media converters can solve the problem by providing a transparent link between twisted pair horizontal cable and the fiber backbone without requiring new cable or replacement of expensive equipment.

For most applications, the economical answer to linking fiber, copper and/or coax is media conversion. Media conversion is the means by which one media type is converted to another media type. Changes in networking equipment driven by the ongoing quest for increased bandwidth, and structured cabling limitations, have helped define the need for media conversion technology. As routers, switches and other network devices evolve at a furiously fast pace, network administrators must develop ways to keep up. This constant migration places demands on both human and financial resources.

Put simply, media converters make one cable “look” like another cable—without changing the nature of your network. A media converter is a small device with two media dependent interfaces and a power supply. They can be installed almost anywhere in your network environment, expanding, rather than limiting your options. Your networking infrastructure, and thus, your investment is protected. Adapting new media types, such as fiber optics, does not require costly hardware upgrades.

The end user has an investment in fiber or twisted pair and is understandably reluctant to toss that investment out the window to achieve a faster network. Even going from copper to fiber or copper to copper presents a challenge. Most enterprises are not financially prepared to put in an entire new infrastructure to meet the needs of a new application. Media converters ease that transition by converting a variety of media to another: coax to twisted pair; coax to fiber; twisted pair to fiber and single mode to multimode fiber.

The device itself has two media dependent interfaces and a power source. The style of connector depends on the selection of media to be converted by the unit. For example, in a Fast Ethernet environment a 100BASE-TX to 100BASE-FX Media Converter connects a 100BASE-TX twisted pair device to a 100BASE-FX compliant single or multimode fiber port that has either a ST or SC fiber optic connector. Converters are small enough to fit in a hand and can be stand-alone units on their own. Don’t be one of those network managers who says, “I wish I’d known last month that it was possible to link TX and FX.”

Check into media conversion. Prioritize the network links which will be upgraded. Use media conversion to bring the different technologies together, keeping the installed base while upgrading on a pay-as-you-go basis. Even if you don’t save money on the actual fiber run, you will save a considerable amount by using the existing electronics.

The alternative to using media converters would be expensive; to put many more hubs out in the network, run new fiber plant, and make sure it would transition from one hub to the other while still maintaining the purity of the signal. Fiber can be connected to almost any legacy environment. Equipment equipped with an AUI or MII port can also make use of fiber transceivers. Media converters can also be used to link single mode to multimode fiber.

Media converters are as simple to install as patch cables and connectors. Media converters function as physical layer devices. As such, they do not interfere with any upper level protocol information. This allows them to support both QoS (quality of service) and Layer 3 Switching.

A fiber media converter can reliably and inexpensively extend the distance between two 10BASE2 devices or two 10BASE-T devices up to 2,000 meters. This function is done without the monetary expense of a repeater or the use of a portion of your network repeater budget. Using media converters in a 100BASE-TX to 100BASE-FX back to back configuration, provides a single method of extending the distance between a full duplex switch and a fileserver up to 2,000

Don’t be one of those network managers who says, “I wish I’d known last month that it was possible to link TX and FX.”

How The Computer Criminals Control Information – Types of Computer Crime

22 Feb

As computer-related crimes become more prevalent, understanding the types of computer-related crimes provides law enforcement an insight for investigative strategies.

The first insight is knowing the types of computer crimes.

Computer as the Target

This computer crime includes theft of intellectual property. The offender accesses the operating program under the guise of the system’s manager. The intruder accesses the contents of computer files in the system through the trap door that permits access to systems should there be a human or technological problem.

Here, the offender uses the computer to obtain information or to damage operating programs while committing the following computer crimes:

* Theft of marketing information, like customer lists, pricing data, or marketing plans
* Blackmail based on information gained from computerized files, like the medical information, personal history, or sexual preference
* Sabotage of intellectual property, marketing, pricing, or personnel data
* Sabotage of operating systems and programs with the intent to impede a business or create chaos in a business operations
* Unlawful access to criminal justice and other government records
* Changing a criminal history, modifying want and warrant information
* Creating a driver’s license, passport, or another document for false identification
* Changing tax records or gaining access to intelligence files
* Techno-vandalism through unauthorized access to damage files or programs
* Techno-trespass violating the owner’s privacy as in criminal trespass

Computer as the Instrumentality of the Crime

Here, the processes of the computer facilitate the crime.

The computer criminal introduces a new code (programming instructions) to manipulate the computer’s analytical processes and for converting legitimate computer processes for the following illegitimate purposes:

* Fraudulent use of automated teller machine (ATM) cards and accounts
* Theft of money from accrual, conversion, or transfer accounts, credit card fraud, fraud from computer transactions like the stock transfers, sales, or billings and telecommunications fraud
* Billing charges to other customers through cellular phones
* Once they capture the computerized billing codes, the computer criminals program these codes into other cellular phones simply by hooking up the phone to a personal computer
* Using software originally developed by programmers in other countries they reprogram the signal chip in the cellular phone
* Share the same through underground computer bulletin board services (BBS)

Computer is incidental to other crimes

In this category of computer crime, the computer is not essential for the crime to occur.

In every following case, the systems merely facilitate the offenses:

* Helping the computer crime to occur faster
* Processing of greater amounts of information
* Making the computer crime more difficult to identify and trace
* Unlawful banking transactions and money laundering
* Supporting unlawful activity via BBSs
* Erasing or denying proper access of organized computer crime records or books, and bookmaking involving drug raids, money laundering seizures, and other arrests in encrypt the data or design
* Allowing computer criminals to destroy the storage media, such as disks, to eliminate evidence of their illegal activities
* Letting child pornographers exchange information through BBSs

These computer crimes require unique data recovery techniques in order to gain access to the evidence.

Computer Crimes Associated With the Prevalence of Computers

The presence of computers, and microcomputers, generates sinister mutations of the traditional crimes like the software piracy/counterfeiting, copyright violation of computer programs, counterfeit equipment, black market computer equipment and programs, and theft of technological equipment.

* Violation of copyright restrictions of commercial software can result in the staggering loss to businesses
* Hackers break into computers with the help of the software illegally written and sold
* Successful computer programs, like the word processing, spreadsheets, and databases are duplicated, packaged, and sold illegally on a large scale
* Just like the pirated audio and video tapes, counterfeit computers and peripherals (items such as modems and hard disks) are also manufactured and sold under the guise of originals

Legal Issues Of Computer Crimes

Some States have enacted laws specifically directed toward computer crimes, while other States rely fundamentally on the common law as it applies to current and emerging technology. The elements of a computer-related offense must be established for successful prosecution.

* The physical act of a computer crime, actus reus, may be demonstrated best by an electronic impulse
* It is difficult to define and track
* A computer crime can occur in 3 milliseconds using a program code that tells the software to erase itself after the computer executes the action eliminating the evidentiary trail
* Causation relates to the self-destruction of computer programs that facilitate computer crimes and an investigator can not show causation if the offender erases the executing instructions
* The electronic data interchange (EDI) and its networks complicate the legal elements by making computer crimes more difficult for law enforcement to specify, document, and materially link the crime to an individual
* The EDI connects parties via computer for contract negotiations, sales, collections, and other business transactions
* The computer becomes the vault, with the EDI serving as the key to its contents
* The ability to access data in the computer must be relatively easy in order to maximize business efficiency
* Security controls must be introduced in order to protect the business’ “crown jewels”
* Maximum security and easy accessibility are not compatible: As the businesses prefer user-friendly equipment, system security usually takes second priority
* The phenomenal growth of computer BBSs, on-line services, and the Internet only serves to compound the problem

As a result, computer-related crimes become easier to perpetrate and more difficult to identify, investigate, and prove.

Special Problems with Computer Crime

Intellectual property consists of concepts, ideas, planning documents, designs, formulas, and other information-based materials intended for products or services that have some commercial value or represent original thoughts or theses. Crimes associated with intellectual property focus primarily on theft when the product has commercial value, as opposed to basic research or research for private use.

Intellectual Property:

* Involves formulas, processes, components, structure, characteristics, and applications of new technologies and covers such areas as fiber optics, computer chip designs and conductivity, and telecommunications equipment, protocols, and technologies
* Associated with the marketing and production of new technologies
* Pricing information, marketing targets, product release dates, and production timetables

Computer Crimes by Malfeasance

The concept of computer crimes by malfeasance means that computer-related behavior stretches the bounds of legality and may be viewed as only technically wrong.

Some of the scenarios of malfeasance computer crimes:

* A parent offers to copy a computer program for a school that cannot afford to buy the software
* An employee secretly maintains a small database in an office computer as part of a sideline business
* An individual uses someone else’s computer account number and password to view the contents of a database
* A customer gives her unlisted telephone number as part of a sales transaction at a store. The store enters the number into a computerized database and later sells the data to a telemarketing firm without the customer’s permission
* A university computer programmer develops a program to schedule classes as part of a job assignment. The programmer then accepts a job with another university and leaves with a copy of the program for use at the new place of employment

These computer crimes illustrate the gray areas of computer abuse, areas that fall increasingly on the shoulders of law enforcement to address and resolve.

International Issues:

Technological knowledge and expertise contribute to the growth of computer crime on an international level.

Businesses can make great use of the

* Unifying measures
* Open communications like the single, European-wide communication protocol
* Strong profit-oriented EU market spanning 12 countries
* Open borders
* Unification of technology standard
* Easier banking
* Monetary transfers between countries

Computer criminals are taking undue advantage of all these issues as:

* Emerging international crime-related issues
* Industrial espionage/competitive intelligence
* Economic/political espionage
* Expansion of international organized crime beyond traditional areas
* Theft of technological hardware

Computer criminals have adapted the advancements of computer technology to further their own illegal activities. Unfortunately, their actions have far out-paced the ability of police to respond effectively. Protocols must be developed for law enforcement to stall the various categories of computer crime. Investigators must know the materials to search and seize the electronic evidence to recover, and the chain of custody to maintain.
