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.
How many disk drive are there in a computer and what are there?
As many as needed.
In laptops/notebooks there is usually only one hard disk.
In a desktop or server there could be potentially any number of disk drives.
If you mean a CD/DVD drive the same applies.
CMOS ( Complementary Metal-Oxide-Semiconductor )
What is 3.5 ghz in Intel i7 processor?
in computing, a 3.5 GHz processor can produce 3.5 billion cycles per second. a cycle in computing refers to the process of "fetching, decoding, and executing". The faster it can do this, the more things the CPU can process.
How many PCs are sold in a year?

There is no such thing as a "mega bite" However.... There are 8 bits in a byte. Mega means 1000. "Megabit" means 1000 bits. "Megabyte" means 1000 bytes. Since there are 8 bits in a byte, there are 125 bytes that make up 1000 bits (1000 bits divided by 8 bytes per bit = 125) A megabyte = 1000 bytes. Therefore there would be 8,000 bits in a megabyte. (8 bits per byte).
What are the common jumper settings for hard drive configuration?
Primary master and secondary master
Which version of raid is supported by windows xp does this raid version provide fault tolerance?
Windows XP supports spanned and striped RAID 0 volumes Hardware RAID is considered a better solution for fault tolerance than software RAID RAID 0 does not provide fault tolerance

Does an external device such as printer and scanner plug into in the back of the computer?
This sort of device usually does come with a USB connection and USB socket could be located at the back of your computer (they may also be located elsewhere on the computer). However modern Printer/Scanners are usually connected wirelessly using the services of your WiFi LAN. This makes them available to more than just one computer.
How do you transfer emails to CD?
You can download an E-Mail client like Mozilla Thunderbird and download all the E-Mails to your computer in one swoop. There will be one file in Thunderbird folder that will contain all the E-Mails in it. I don't think u can open the E-Mails directly but you can burn this file onto a CD and then open this file through Thunderbird and view the E-Mails anytime on any computer. I don't remember what the file is called but if you look for it it will be exceptionally large (that is if you have a lot of E-Mails)
Download Thunderbird Here: http://www.mozilla.com/en-US/thunderbird/
Same can probably be done with the default Microsoft E-Mail client Outlook pre-installed on every Wndows running computer. But i have never tried using it for that.
Warning: by default, downloading all of your E-Mails will erase them from your website view email (ex. Yahoo.com). That can be prevented by changing that option in your E-Mail settings before you download all of the E-Mails.
Short Answer: 2 Megabytes is equal to 2,048 Kilobytes (2 MB = 2,048 KB)
Detailed Answer -- Bits, Bytes, Kilobytes, and more...
Computers are electronic devices so they view everything as either being ON or OFF. By stringing together groups of on and off messages, computers can store and process information.
The code for ON and OFF are represented numerically as either a one (1) or a zero (0). 1=ON, 0=OFF. Individually, each one or zero is called a Binary Digit or BIT for short.
A collection of 8 BITS (or eight zeros and ones) is equal to 1 BYTE
In human terms, 1 BYTE is equal to one character (a letter, number, space, dash, etc.)
For example, when you type the letter "A" your computer sees "01000001" and if you type the letter "a" in lowercase it sees "01100001." Each zero and one by itself is a BIT; each collection of eight BITS makes up one BYTE.
1 BIT = 1 BINARY DIGIT (either a 0 or a 1)
1 BYTE = 1 CHARACTER
1,024 BYTES = 1 KILOBYTE (KB) (one typewritten page is about 2 KB)
1,024 KILOBYTES = 1 MEGABYTE (MB) (a complete novel is around 2 MB)
1,024 MEGABYTES = 1 GIGABYTE (GB) (a stack of books 60 feet high would fit in 2 GB)
1,024 GIGABYTES = 1 TERABYTE (TB) (all the books in a major research library = 2 TB)
1,024 TERABYTES = 1 PETABYTE (PB) (every book in every US library = 2 PB)
1,024 PETABYTES = 1 EXABYTE (all the words ever spoken by humans = 5 EB)
Kilo K = 1,024
Mega M = 1,048,576
Giga G = 1,073,741,824
Tera T = 1,099,511,627,776
Peta P = 1,125,899,906,842,624
Exa E = 1,152,921,504,606,846,976
Zetta Z = 1,180,591,620,717,411,303,424
Yotta Y = 1,208,925,819,614,629,174,706,176
Do you need a modem for dial-up internet?
A modem is only required if you wish to connect your laptop to the internet via a phone line. Most people now connect to the internet using a broadband modem which is a separate device. Most laptops now come with wireless networking capability. Built in modems are becoming less common.
use of ram:- use it as primary storage. suppose you put a data into it.ram is the only who save the data for primary time.
Difference between central devices and peripheral devices?
A peripheral device, more commonly referred to as a peripheral, is a "device attached to a host computer behind the chipset whose primary functionality is dependent upon the host...".
Thus, a peripheral is any device you attach to your computer which is not central to your computer's standard operation. Printers, scanners, game controllers, and security dongles are all examples of peripherals.
This definition can be found here: http://en.wikipedia.org/wiki/Peripherals
The term "hardware device," however, seems a redundant phrasing, since any "device" by definition would be hardware.
How does a scanner input data?
A scanner scans the documents and make a image of that.Hence scanners input the images by scanning pages.
How many picture can you store on a 4GB memory card?
The capacity of a card indicates the maximum amount of data that can be stored (less some space for the card's own use).
Megapixel (MP) count refers to the maximum resolution of the camera's sensor -- its ability to record detail. The number of images that can be recorded on a card of a given size is only indirectly related to the capacity of the card, which is measured in Kilobytes (KB) or Megabytes (MB), not MP. That will vary according to the image itself, and to the camera's settings.
For example: My Pentax K10D, with a 10.1 MP sensor and using a 4 GB card, will record approximately 821 images at the highest resolution (10 MP) and a "Fine" setting. The same camera, with the same sensor and same card, will record 10,000-plus images at the lowest resolution (2 MP) and the "Low" setting. Practically all cameras have this ability to change the resolution settings, and thus the sizes of the image files that are stored on the card.
So, you can see that it is only possible to answer your question in very general terms: The higher the capacity of the card, the more images you can store at whatever camera settings. And, as you can see above, even at the highest settings with a high MP count, you can take a lot of pictures!
One thing to think about: storage cards can and do fail. It is better to have two 1 GB cards than one 2 GB card, unless you plan to shoot a whole lot of video. That way if one fails, you can keep shooting and worry about retrieving the images off the other card later.
How do you turn on the bluetooth on a dell N4010?
1st install dell quickset driver.then click f2.there is icon appear on the bottom right corner of your screen which has 2 icons,one is on & one is off. a white colour box present on either of the icons .please make sure that the white colour box is over the on icon.then install the bluetooth application driver from dell official site.it will work.
What are the port expander advantage and desadvantage?
Well, depending on what you are using it for there are different kinds of advantages and disadvantages.
If you are using it on a desktop or home computer one of the advantages is the ability to allow more devices of a particular port type to be utilized at the same time. One disadvantage is if you have a 3Gbps port, with a port expander installed that can support up to seven devices, only has a max of 3Gbps throughput bandwidth divided by each device; or however many are plugged in and being used. The more devices you have plugged in the less throughput bandwidth that port can use.
How do you connect N router with wireless G card?
In the wireless properties choose "compatibility mode for G" or something like that. If you do so your router will allow both types of wireless cards G and N.
