Microsoft Corporation (NASDAQ index: MSFT) was created in 1975 by Bill Gates & Paul Allen.
Which connecton type supports upto 127 peripherals in a single connections?
Theoretically, you can use a USB port to connect up to 127 devices. To do so, you would need to use hubs. The problem with using hubs is that they count as devices. Thus if a hub has 4 sockets, it counts as 5 of the 127 devices.
What storage devices contains no moving parts and connect directly to a USB port?
Assuming you mean a data-storage device (for use with computers) then the most clear cut answer would be a CD-ROM or a DVD-ROM, neither of which have any moving parts by themselves. The disc-reader however would have moving parts which may negate the idea of a stationary storage device.
Flash memory is another form of storage which is commonly found in USB drives and small electronics. It has no moving parts.

Vm-ware is the software allows us to install 2 O/S in your PC. Then we can use both operating systems by minimizing the window. It allows to use parallel Operating systems. sorry if the answer is not right.
Where is the functions key on a laptop?
It is the key that allows the standard keys on the keyboard to have additional "functions". Common uses for the function key include turning the keys IOPKL;M,. into a number pad. Also function keys are used for things like lowering and raising the speaker volume, putting the laptop into sleep/hibernate mode, changing the display used for output, and launching favourite applications.
The EDO RAM desktop memory modules have 72 pins and operate at 5V as standard
List four symptoms that indicate a faulty power supply?
1) The power reading (battery moitor) changes frequently, up and down, or is always unsure 2) The computer shuts down through loss of power when it seems to be on full power 3) the power cable is damages, very old or has been faulty in the past
It takes some experience to know when this type of failure is power related and not caused by the memory. One clue is the repeatability of the problem. If the parity check message (or other problem) appears frequently and identifies the same memory location each time, I would suspect that defective memory is the problem. However, if the problem seems random, or if the memory location the error message cites as having failed seems random, I would suspect improper power as the culprit. The following is a list of PC problems that often are related to the power supply: * Any power-on or system startup failures or lockups. * Spontaneous rebooting or intermittent lockups during normal operation. * Intermittent parity check or other memory-type errors. * Hard disk and fan simultaneously failing to spin (no +12v). * Overheating due to fan failure. * Small brownouts cause the system to reset. * Electric shocks felt on the system case or connectors. * Slight static discharges disrupt system operation. In fact, just about any intermittent system problem can be caused by the power supply. I always suspect the supply when flaky system operation is a symptom. Of course, the following fairly obvious symptoms point right to the power supply as a possible cause: * System is completely dead (no fan, no cursor) * Smoke * Blown circuit breakers
In a system that uses a CD drive were the audio wire connects?
There is a data cable,and a power cable that connect the drive to your PC.
Everything is done with the data cable, there is no audio or video wires.
Its more of an bidirectional device......it shows u the output graphic data as well as helps u select ur option.........
What is the difference between a CD burner and a CD writer?
It's the same with DVD optical drives. A Blu-Ray reader (or player) is a drive or a stand alone home theater appliance that can play or read Blu-Ray movies or read Data on Blu-Ray discs. A blu-Ray burner is a drive that can write or "burn" data on Blu-Ray discs.
I'm actually using a USB Blu-Ray burner with my system. It's from a company called DIGISTOR. Very very nice. Hope the answer helped.
In the back of most desktop computers are removable tabs that cover slots that have been cut into the frame. When you remove the cover from your computer you will see that there are slots which align with the tabs. A tab can be removed and an interface card can be installed at that location. PCI BUSS and PCI slots are one of the types of communication formats used by desktop computers.

How do analog and digital computers differ?
A digital computer processes discrete data, an analog computer processes continuous data.
- Discrete data (integers, character codes, boolean values, encoded floating point numbers, etc.) represent information with sharp discontinuities between represented values. Any data value not exactly encoded must be approximated by one of the nearest encoded values. Operations on discrete values are more reliable and consistent, but usually slower with identical technologies.
- Continuous data (voltages, currents, fluid pressure, fluid flow, shaft position, shaft rotation rate, etc.) represent information by analogy. All data values (within the limits of the machine) have an equivalent representation. Operations on continuous values are less reliable and less consistent, but usually faster with identical technologies.
Analog computers are typically harder to program: they are either designed for one special purpose with the program permanently built in, or they must be "rewired" to reprogram them.

FOR THE TEACHERS
You can't make the students learn better by changing the answer to the wrong one.
The humanity is positively progressing because the internet allows people to share the knowledge much faster.
By changing the answer to the wrong one you will only succeed in producing more Ds
Progress is= to knowledge share, do not slow it down!!!

P.S. A student is here because either he/she is not interested in a subject or a teacher is not good.
What is the average memory of RAM in a computer?
Most computers in 2008 come with at least 1 GB (even laptops). You should get around 2 GB if you're going to do alot of work on the computer such as editing photos or editing videos. However, for a casual user who is surfing the web or using MS Word/Excel, even 512 MB would be enough.
What could cause a computer monitor to burn out or die?
I had a 17" CRT that died in front of me one day - and it taught me an important lesson. I was working at my home PC when I heard a faint pop sound, and the screen went dark. Living by the philosophy of looking for the most likely causes first, I checked the power cable (fine), the power strip (also fine), then completely disconnected the monitor from the PC and power, got out the screwdrivers and openedup the casing. I pulled out a fuse and used a tester on it; sure enough it was blown, and I could fix it for about $3.99 and a 2-minute visit to the hardware store across the street. If I had taken it into a repair shop, it would have cost me $50 just for them to open up the case and replace it themselves.
Which is the smallest increment of data in a computer system?
A bit is a binary digit that is the second smallest increment of data on a computer. It can hold only two values which are 0 and 1.
AMD (acronym for "Advanced Micro Devices") is a US-Based manufacturer of semiconductors and computing products. Some of AMD's consumer products include: laptops, desktop computers, tablets and embedded computing solutions.
Which multimeter setting to test power supply of a computer?
That depends on what you're testing it for.
You would mostly use the volt meter settings to test for proper voltage output at the connectors coming out of the power supply. After verifying the expected volt output from a suspect connector, You should, in case you are wrong or a short is present, start with the highest voltage AC settings first and then reduce to lower settings and DC to confirm proper outputs.
What is the primary communication device for a computer?
Mobile phone is the most wide used device. After that Calculator and then comes in laptop and PC.
How wide can the external data bus be?
The external data bus can be as wide as desired, given the necessary compromises between performance, complexity, and cost. The wider the bus, the faster the theoretical aggregate data transfer rate.
In the 8085 and 8088, the external data bus is 8 bits wide; in the 8086, it is 16 bits wide; in the 80386, it is 32 bits wide; and in the modern incarnations of 64 bit processors, it is 64 bits wide.
When devices interrupt occurs how does the processor determine which device issued the interrupt?
It's pretty simple. First, the processor must determine which interrupt occurred. On simple hardware setups, you may already know this just by which interrupt handler was called. On more complex hardware, you may have to read status registers in the interrupt controller.
Second, the processor has to look up which devices are capable of asserting that interrupt. On simple hardware, generally there is only one device that can trigger each interrupt and this is determined by the way the device is wired. On more complex devices, this may be determined by software and the processor may have to consult tables that were created during the boot process.
Third, the processor must determine which of those devices actually asserted the interrupt (if there's more than one). This is typically done by the driver for each device which generally just asks the device if it triggered an interrupt. Most devices have status registers that either directly tell you whether it caused an interrupt or tell you whether the device needs service which was the point of the interrupt anyway.
What is the relationship between hardware and software and data?
Hardware, software, and data are interdependent components of computing systems. Hardware refers to the physical devices that execute processes, while software comprises the programs and applications that instruct the hardware on how to perform tasks. Data is the information processed and generated by software, which the hardware stores and manipulates. Together, they enable the functionality of computer systems, with hardware providing the infrastructure, software guiding operations, and data serving as the input and output of these operations.
