A small electronic chip a manufacturer programs for use in another product is?
programmed chip
Types of device drivers?
There are only two types: software and firmware. A software device driver is a program written for a particular operating system to support a particular piece of hardware. A firmware device driver is also software, but it is etched onto a memory chip (ROM) or a programmable chip (PROM or EPROM). The BIOS and CMOS are examples of firmware drivers, both used to initially boot the system and load the operating system.
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 does embedded mean?
'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".
Definition of multi-core processor?
A multi-core processor is one which combines what are essentially multiple CPUs into a single chip. As far as the operating system and other software are concerned, it is the same as a dual or quad-cpu computer system, even though the cpus are physically one single unit.
What kind of operating system that resides on rom chip inside a pda is called?
Obviously many different PDAs have different names for their operating systems. But generally you would call it an embedded operating system, as it is running on an embedded device.
The operating system on many mobile devices resides on a chip?
ROM
What operating system resides on a ROM chip inside a PDA?
utility program
Would an operating system be an information system or an embedded system?
If you are talking about a P.C (or Mac) operating system, then it would be an information system. An embedded system is something like that in a modern washing machine. It only deals with a pre- set range of parameters, and is often run on specifically designed hardware, with the memory containing the "system" physically attached to the chip.
Difference and similarities between embedded systems and general purpose workstations?
ð An embedded system is differ from the general purpose in the view of their purpose. The general purpose computers are the computers that are designed to perform many operations and which can be reconfigured for a new purpose where as an embedded is designed only meant for one purpose.ð An embedded system has a self-contained operating system on a "chip" hence embedded into the system and does not depend on having a hard disk with the operating system on it, whereas in the general purpose computer an operating system need to be present in the hard disk.ð Example for an embedded system is a portable music player; example for general purpose computer is PCs.
Why MS-DOS is called so?
MS - Microsoft DOS - Disk Operating System. This indicates that the operating system was stored on disks, as opposed to being embedded in a RM chip or stored on cartridges, tape, or punch cards.
Why is an operating system software handed from hard disk then a Rom chip?
The operating system has nothing to do with the ROM chip
State the storage medium used by an embedded system?
On a ROM chip.
What are the difference between VLSI and embedded design?
how to make a chip ---- vlsi how to use a chip ---- embedded systems
A chip designed with a specific set of usable instructions?
A chip designed with a specific set of usable instructions is called an embedded processor. An embedded processor is a type of CPU chip that cannot be used in a system that is a general-purpose workstation, laptop or desktop computer.
Why is an operating system called disk operating system?
An operating system is / was called a "disk" operating system because it was stored on a floppy disk or hard drive, as opposed to either being embedded in a ROM chip (like early versions of Mac OS were), or stored on a cartridge, cassette, tape reel, or some other storage medium. The usage fell out of favor due to the popularity of MS-DOS: "DOS" was thereafter used to refer only to MS-DOS or compatible operating systems.
Does the Real ID card have an RFID chip embedded in it?
Yes, the Real ID card does not have an RFID chip embedded in it.
