What is difference between microprocesser and microcontroller?
An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software. Many of today's embedded systems are looking more like PCs with user interfaces, touchscreens, displays, keypads and more. Still, these are not general function systems but are designed to perform very specific functions. An embedded system makes use of embedded hardware (microprocessor) and embedded software to accomplish its purpose. Embedded software is generally comprised of: * Real-time operating system (RTOS) * Drivers (HW peripheral interface) * Application software
Give two examples of number systems that were created by the sumerians and are still used today?
They were the first group to use numerals. They also worked with bases of ten, bases of 60, and the decimal system that is still in use today.
What is the Parabolic SAR formula?
SAR tomorrow = SAR today + AF(EP trade - SAR(today) where AF = acceleration factor and EP is highest high reached yesterday From New Concepts in Technical Trading Systems by Wells Wilder.
How many volt DC systems are typically used in a car?
Most new automobiles today use a single 12 VDC electrical system with the negative terminal of the battery grounded to the frame of the auto.
How does closed-circuit TV work?
Closed-circuit television (CCTV) is the use of television cameras to transmit a signal to a specific, limited set of monitors. It differs from broadcast television in that all components are directly linked, and that the signal is not openly transmitted, though it may employ point to point wireless links. CCTV is often used for surveillance in areas where there is an increased need for security, such as banks, casinos, and airports. They may also have military uses. The use of CCTVs in public places has increased, causing debate over security versus privacy. CCTV was developed as a means of increasing security in banks. Today it has developed to the point where it is simple and inexpensive enough to be used in home security systems, and for surveillance.
Is lift an embedded system?
An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software. Many of today's embedded systems are looking more like PCs with user interfaces, touchscreens, displays, keypads and more. Still, these are not general function systems but are designed to perform very specific functions. I would certainly include lifts (elevators) as an embedded system. Today's lifts include detailed control systems that not only manage lift operations but include capabilities to link to other building control systems and off-site monitoring stations.

What are the necessity of embedded systems?
An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions,[1] 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 micro controller 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.
What is embedded system?
# A specialized computer system that is part of a larger system or machine. Typically, an embedded system is housed on a single microprocessor boardprograms stored in ROM. Virtually all appliances that have a digital interface -- watches, microwaves, VCRs, cars -- utilize embedded systems. Some embedded systems include an operating system, but many are so specialized that the entire logic can be implemented as a single program. # Embedded System is: specified purpose controller which is embedded as part of larger system. An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software.

What is microcontroller 8051?
The 8051 is a microcontroller. It has the MCS-51 core by Intel and was designed for embedded systems in the 1980's. The name of the CMOS version is 80C51. Today the core is still used in microcontrollers from other companies like Atmel, e.g. AT89C51.
What does embedded?
'Embedded' simply means 'placed within', for example,He saw a glistening crystal embedded in the solid rock...meaning...He saw a glistening crystal placed within the solid rock. An embedded system is a computer system designed to perform one or a few dedicated functions[1][2] often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today.[3]Embedded systems are controlled by one or more main processing cores that are typically either microcontrollers or digital signal processors (DSP).[4] The key characteristic, however, is being dedicated to handle a particular task, which may require very powerful processors. For example, air traffic control systems may usefully be viewed as embedded, even though they involve mainframe computers and dedicated regional and national networks between airports and radar sites. (Each radar probably includes one or more embedded systems of its own.)Since the embedded system is dedicated to specific tasks, design engineers can optimize it to reduce the size and cost of the product and increase 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 MP3 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 a strictly definable term, as most systems have some element of extensibility or programmability. For example, handheld computers share some elements with embedded systems such as the operating systems and microprocessors which power them, but they allow different applications to be loaded and peripherals to be connected. Moreover, even systems which don't expose programmability as a primary feature generally need to support software updates. On a continuum from "general purpose" to "embedded", large application systems will have subcomponents at most points even if the system as a whole is "designed to perform one or a few dedicated functions", and is thus appropriate to call "embedded".

What is difference between an embedded system and a general purpose computer?
An embedded system has a self-contained operating system on a "chip" thus embedded into the system and does not rely on having a hard disk with the operating system on it. Not to mention that is will be much faster because the access time of the OS on a chip. More specifically... An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software. A PC is designed to be a general purpose computing environment. Many of today's embedded systems are looking more like PCs with user interfaces, touchscreens, displays, keypads and more. Still, these are not general function systems but are designed to perform very specific functions.
Can a video be embedded in a song?
Yes. For such kind of operations you will need a video editing program. In most operating systems today, there are pre installed video editing programs. For example in Windows there is Windows Movie Maker.

What is exact definition for embedded system?
An embedded system is a special purpose system, in which the computer is encapsulated by the device it controls. Unlike a general purpose system an embedded system will only perform some particular tasks. These are actually systems which are developed for performing some predefined tasks. Embedded systems may vary from small hand held devices like PDAs to large devices like robotic arms.Embedded systems are generally control systems which are a part of another device and they can handle the entire operation of that device. They are generally electronic chips with CPU, memory,I/o ports and are programmable.
