Television

•May 6, 2009 • Leave a Comment

Television(TV) is a widely used telecommunication medium for transmitting and receiving moving images, either monochromatic (“black and white”) or color, usually accompanied by sound. “Television” may also refer specifically to a television set, television programming or television transmission. The word is derived from mixed Latin and Greek roots, meaning “far sight”: Greek tele (τῆλε), far, and Latin visio, sight (from video, vis- to see, or to view in the first person).

Commercially available since the late 1930s, the television set has become a common communications receiver in homes, businesses and institutions, particularly as a source of entertainment and news. Since the 1970s the availability of video cassettes, laserdiscs DVDs and now Blu-ray discs have resulted in the television set frequently being used for viewing recorded as well as broadcast material.

Although other forms such as closed-circuit television are in use, the most common usage of the medium is for broadcast television, which was modeled on the existing radio broadcasting systems developed in the 1920s, and uses high-powered radio-frequency transmitters to broadcast the television signal to individual TV receivers.

E-Commerce

•May 2, 2009 • Leave a Comment

What Is E-Commerce?
Simply put, e-commerce is the online transaction of business, featuring linked computer systems of the vendor, host, and buyer. Electronic transactions involve the transfer of ownership or rights to use a good or service. Most people are familiar with business-to-consumer electronic business (B2C). Common illustrations include Amazon.comimagesimages1, llbean.comimages2, CompUSA.com, travelocity.com, and hotels.com.

E-commerce can be divided into:

E-tailing or “virtual storefronts” on Web sites with online catalogs, sometimes gathered into a “virtual mall”
The gathering and use of demographic data through Web contacts
Electronic Data Interchange (EDI), the business-to-business exchange of data
e-mail and fax and their use as media for reaching prospects and established customers (for example, with newsletters)
Business-to-business buying and selling (B2B)

Are You E-Commerce Ready?

Companies that have decided on how to portray their business online must assess whether they have the most efficient information technology (IT) solutions to execute their online exporting programs. IT embodies a range of computer systems and software applications for managing a firm’s web site, as well as personnel records, back end databases, etc. With more and more cyber attacks on government and corporate sites, companies should invest in security technologies to protect themselves and their customers from identify theft and denial of service.

An IT assessment should answer the following questions:

What is the firm’s current IT usage? Is it at capacity? What are the plans for additional ITinvestment to upgrade existing systems?
What business applications are best suited to move on line for B2B or B2C electronic?
What does the cost/benefit analysis of all possible projects involving IT show?
What are possible current and future security issues and what is the action plan for correcting problems?
There are, of course, many other factors to consider in doing international e-commerce, such as executing orders and payment issues that have a special e-commerce perspective, which are are addressed in other parts of this site.

Computer Radiation

•April 22, 2009 • Leave a Comment

Studies show that long-term exposure to radiation increases the risk of all forms of cancer, tumors, blood disorders, miscarriage, headaches, insomnia, anxiety, aging of the skin, skin burn, etc.

Radiation exposure over time can cause skin burn, dry wrinkled skin and photo aging. This skin damage is identical to sun damage and causes the same health problems. Many electronic products that we use on a daily basis expose us to harmful radiation.

A television, microwave oven, cellular phone and computer are examples of products that emit radiation. To preserve your health use electronic products carefully, in ways that shield your body from radiation.

Computer radiation is most harmful to skin health because we sit directly in front of the computer for long periods of time with our face absorbing the radiation. Lessening this type of harmful radiation is important.

Computer radiation can make you feel sick and burn your skin. Most people are not aware of this, and continue to suffer with ill health they have no explanation for. They do not realize sometimes ill health is related to computer use.

Using a laptop or LCD does not exclude you from the negative health affects of computer radiation. All computer monitors emit low levels of radiation. Laptops and LCD monitors emit less radiation than the old-fashioned CRT monitors. However, all monitors emit enough radiation to affect your health and appearance.

A healthy solution is to use a computer accessory called a radiation filter. This product will eliminate 94-99% of the harmful radiation emitted from your computer screen. Radiation filters are available for all types of computer monitors, and they work well to protect you from radiation.

It is also helpful to move the processor tower as far away from your body as possible. This will reduce radiation that could reach and affect your body.

The negative health effects of computer radiation are a well-known topic. There is much research on the web that explains its health hazards. But unfortunately, it is also a much avoided subject. Most people do not realize the harm that radiation can cause to the human body, even at low levels. It is also not a widely advertised problem because it would negatively affect industry and the economy as a whole.

By law, there are basic health and safety requirements that manufacturers must meet for electronic products. Many manufacturers today are improving products to emit less radiation, and great technological improvements have been made in the last five years alone. Be health smart and research any electronic product before you buy to make sure it emits low radiation.

Most industry standard computer monitors do comply with low radiation guidelines. However, low radiation does not mean zero radiation. Computer radiation levels are still allowed to be high enough to cause health problems.

It is very important to use products that emit low radiation, and shield radiation emissions. Following this simple advice can help to preserve your health and well being.
