Picture of the internals of a Netgear ADSL modem/router. A modern example of an embedded system
Today I'm going to share some info about embedded system....Just read the texts below:
An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions, often with real-time computing constraints. It is usually embedded as part of a complete device including hardware and mechanical parts. In contrast, a general-purpose computer, such as a personal computer, can do many different tasks depending on programming. Embedded systems control many of the common devices in use today.
Since the embedded system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product, or increasing the reliability and performance. Some embedded systems are mass-produced, benefiting from economies of scale.
Physically, embedded systems range from portable devices such as digital watches and MP4 players, to large stationary installations like traffic lights, factory controllers, or the systems controlling nuclear power plants. Complexity varies from low, with a single microcontroller chip, to very high with multiple units, peripherals and networks mounted inside a large chassis or enclosure.
In general, "embedded system" is not an exactly defined term, as many systems have some element of programmability. For example, Handheld computers share some elements with embedded systems — such as the operating systems and microprocessors which power them — but are not truly embedded systems, because they allow different applications to be loaded and peripherals to be connected.
Well, to know more about embedded system; just google it xP You will find more about it...

Examples of E-commerce,,,
"Bah lajutah...Main trolley..."
"Balitah mana yang suka...Tapi bayar sendiri ah..ehehheh:D"
"Bah..Aku mau bini2 yang migang camera ah...Eyh salah! maksudku camera yang dipigang oleh bini2 atu...Err...Apa brandnya tu?Brapa harganya? Atuwah yo....Aku ada nie jual mainan...mau ko? Cute x ah..*Tukar topik*"
"Oi oi!Siuk sendiri jua..."
"Hye........Eyh, sorry ngacau......."
Hye.... Let's shopping from the internet.....Aku lanja! (Eksen ku plang tu)Electronic Commerce, commonly known as (electronic marketing) e-commerce or eCommerce, consists of the buying and selling of products or services over electronic systems such as the Internet and other computer networks. The amount of trade conducted electronically has grown extraordinarily with widespread Internet usage. A wide variety of commerce is conducted in this way, spurring and drawing on innovations in electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems. Modern electronic commerce typically uses the World Wide Web at least at some point in the transaction's lifecycle, although it can encompass a wider range of technologies such as e-mail as well. A large percentage of electronic commerce is conducted entirely electronically for virtual items such as access to premium content on a website, but most electronic commerce involves the transportation of physical items in some way. Online retailers are sometimes known as e-tailers and online retail is sometimes known as e-tail. Almost all big retailers have electronic commerce presence on the World Wide Web. Electronic commerce that is conducted between businesses is referred to as business-to-business or B2B. B2B can be open to all interested parties (e.g. commodity exchange) or limited to specific, pre-qualified participants (private electronic market). Electronic commerce that is conducted between businesses and consumers, on the other hand, is referred to as business-to-consumer or B2C. This is the type of electronic commerce conducted by companies such as Amazon.com. Electronic commerce is generally considered to be the sales aspect of e-business. It also consists of the exchange of data to facilitate the financing and payment aspects of the business transactions.
EFFECTS OF COMPUTER RADIATION!
Headache in x-ray version
She says:"Wuisshh!Kuat radiationnya atu..Sakit kepala ku!"
He says:"Luan banar eyh! Cuba liat aku. Chill ja main computer..."Headache2
She2 says:"Yes, I support you 1000% sis! Apanih! Ambung jua cakap mu atu..Mun ko yang kana baru ko tau! Control macho tah lagi tu! Sis, kan ke hospital ku..Ada appoinment X-ray kepala..."
Mr.Skull says:"Haha! Au...Ambung banar..Yo she2...If ko x-ray pun..Sama nie usul otak mu macam aku....Doctor Skeleton cakap aku ada migrane..I think you'll get it too..Bowh!!" Insomnia
Mr.Eyeball says:"Sori menyampuk..Bukan saja headache or migrane! You will get Insomnia too! Your face will be all covered by your big eye ball!Nyahahahaha..."Insomnia2
Man says:"Let's count sheeps together! 3508....3507....3506...." Insomnia3
She3 says:"It's 5.00 a.m and I still can't sleep....Man! I'll join you! 3505....3504..3503...Hmm..Oh god.I love sheeps..."
Woman says:"I'm afraid to take them!"
Introduce you this dangerous COMPUTER RADIATION!
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.
