What are the Applications of hybrid computer?
Solving problems that do not adapt well to solution entirely on a purely digital or purely analog computer that is available within the timeframe the problem arose and needs to be solved. Frequently the hybrid computer not only is capable of solving such problems, but is capable of solving them faster than they could be solved on a much more expensive purely digital or purely analog computer that theoretically could solve it, if such a computer was available at that time.
What is the size of the accumulator register of 64 bit processor?
64 bit. the size of accumulator will always equal to the size of processor. e.g 32 bit processor has 32 bit accumulator.
-------------------------------------------------------------------------------------------------------------------------------------------
Actually on some computers the accumulator(s) are larger than the processor word size. Some examples are:
- IBM 704, IBM 709, IBM 7090, IBM 7094 - these are 36 bit processors with a 38 bit accumulator
- IBM 7030 - this is a 64 bit processor with a 128 bit accumulator
Some computers do not have accumulator(s), these fall into three main groups:
- Variable word length machines that store all data in main memory
- General purpose register machines
- Stack machines that either have a fixed sized internal stack or a variable sized stack stored in main memory
ISA devices are [in computing terms] Industry Standard Architecture devices. It is a hardware standard that is/was used in IBM personal computers and their compatibles.
What is the difference between narrow SCSI and wide SCSI?
The wide SCSI-2 uses a wider data path & emdash;16 bit rather than the normal 8 bit & emdash; for the same 10 Mbps. Combining both fast and wide can, in theory, reach 20 Mbps.
What is a 1934 computer port for?
a 1934 port is actually a firewire port, that can be used for high speed data transfers
A LM339 is a small scale integrated circuit(SMIC) that contains 4 "Norton"* comparotors on a single chip. The LM339 is not universal as most Operational Amplifiers are. The comparotors on the chip do not amplify with feedback, rather only switch state(+V, Ground) on their output. The benefit to the "locked" behavior is some of the smallest power drains a TTL chip can provide and fast switching speeds. *Norton denotation indicates that the op-amp/comporator operates from a single suply rail(+V,Ground), where normally you would expect to use a dual supply rail for op-amp/comparators(+V,Ground or V_(same thing), -V).
What does the electrical x4 mean on a PCIe x16 electrical x4?
means it can handle a 16x card, but will only operate at 4x which will result in lower bandwidth..
- computer
- network interface cords
- switch
- router
- modem
- gateway
- communication media
- hub
- network operating system
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
What does es stand for for example in an Intel e6700es?
In computer hardware terms, "ES" stands for "Engineering Sample." This is a product that was manufactured either as a proof of concept or for final analysis before initiating mass production. ES hardware isn't always what the final product resembles, as there may be unlocked or "unnecessary" features that were removed or restricted for whatever reason.
The handles that you cannot hold in your hand are the little squares at the edges and corners of a graphic on the computer screen. The handle can be moved with the mouse pointer to re-size the graphic.
Ports are devices used to connect a personal computer(PC) to external devices,such as keyboards and mice.They are located at the back of the PC.But today,some ports are found on the front of the PC as well.
Is a microphone output or input?
input. The microphone gives a signal to the computer/radio/whatever you're using.
it is input because when you speak into it,it gets in the amplifier and the amplifier processes it to came out as sound through the speaker
How does a constant current power supply works?
these are essential for circuits which are current sensitive, it regulates the amount of current which serves as protection for circuits. it is commonly used in Laser diode applications.
Does a resistor only decrease current in a circuit?
A resistor does not only decrease current in a circuit it can also reduce tension(voltage) if connected in series.
What is default Belkin ups password?
Most belkin routers don't have a password. Try leaving the field blank and try again. If that doesn't work, reset the router to default and try again. it'll work.
A firewall is a combination of software and hardware that helps prevent unauthorized access to a system through the Internet. Modern Windows OS's feature an inbuilt firewall.
What is the explanation for the features of repeaters?
Signal strength diminishes over distance. A repeater boosts signal strength and passes it on.
Who created the image scanner?
An image scanner optically scans images, printed text or handwriting and converts it to a digital image. It was invented by Ray Kurzweil.
What is the difference between a personal computer a server computer?
A server computer serves other computers (in a network) with programs and/or files. Think of it like a cafeteria. You get your tray (computer), walk down the line (pull down the file menu), when you see something you need or want you ask for it to be put on your tray (downloaded to your desktop computer). Your desktop computer is the same as a personal computer.
