What is another term for the system bus?
Upgradable computers have what is called an expansion bus or peripheral bus. While that is technically a "system bus," a system bus could include the traces traveling from the CPU to the chipset (particularly the "Northbridge" in computers not using CPUs with an integrated memory controller). Or it could include the traces between the memory and the memory controller (if one is used) or the CPU. So there are multiple system buses in a computer.
There is also such a thing as a "local bus," and that is when there are traces directly between the CPU and the peripherals (VESA Local Bus, for instance). While AGP sockets in computers with those communicated with the CPU rather than the chipset, that was technically not local bus since AGP operated independently of the CPU and had their own clock rate derived from the CPU clock.
What is the full meaning of AGP in computer?
An AGP slot is a dedicated local bus found on many motherboards. It is used for high-performance video cards.
AnswerThe Accelerated Graphics Port (also called Advanced Graphics Port) is a high-speed point-to-point channel for attaching a graphics card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics. Some motherboards have been built with multiple independent AGP slots. AGP is slowly being phased out in favour of PCI Express. AnswerIn computer jargon, AGP means Accelerated Graphics Port, and is used to generate video images based upon graphic generator programs. This is the port commonly used for games, which require that the image displayed on the monitor be calculated from a data stream, rather than simply passed through the computer like a television signal. Many high level gamers prefer to use graphics generated by specialized video/graphic cards, which are added to the motherboard of the computer. These cards have separate processors for decoding and generating video, and are able to create high resolution graphic images at a much faster rate than graphics chips which must rely upon the CPU to process the graphics output. The Accelerated Graphics Port is where these specialized cards are installed on the motherboard, where they are able to receive the graphics data stream prior to it entering the CPU, if I remember correctly.AGP Stands for Accelerated Graphics Port. An AGP port is specifically used to connect a graphics card. For more information on AGP, go here:

How many megabytes in 38.42 gigabytes?
In one Gigabyte (GB) there is 1024 Megabytes (MB). In 1MB there is 1024KB (Kilobytes). In 1KB there is 1024 bytes.
The answer to your question is 8192MB
What is the difference between socket 775 and lga 775?
The socket 775 and the LGA 775 are the same. If you want to get technical it's not really a socket CPU, as the pins themselves are located on the socket grid and the back of the processor is flat with contact points. Totally opposite of what were used to seeing. Intel designed it this way to take increase the power distribution.
The term LGA stands for Land Grid Array
What are the challenges of using information systems in an organisation?
There are many major challenges to information systems in organization. One of these major challenges is that information can get crossed.
What is another name for voltage?
Voltage can also be called "potential" and is measured across components or sections of a circuit.
Answer'Voltage' is another word for 'potential difference', not'potential'!
A worksheet is an arrangement of rows and columns, making up cells into which various types of data and formulas can be entered. Each row is numbered. Each column is headed by a letter or combination of letters. A number of worksheets are contained in what is called a workbook.
In "computer speak" a word is a specific amount of storage. The exact size of a word varies from machine to machine, however. If you read that your system has an 8-bit word, then it means that any time you see "word" you can think of 8 bits (and if you see "double word" or "quad word" you can think 16 bits or 32 bits, respectively).
Can a CD player read a CD from both sides?
No. There aren't any CD's that contain data on both sides, because the tehnology doen't allow it. There are lightscribe discs though. these are blank on both sides. Where one side is for data, and the other is for printing a label.
What are programs that give instructions to a computer called?
Programs run by a computer are called software
How do you find an IP address using Windows XP?
* Press the keys Win(Windows Logo)+R. * Type cmd and press enter. * When the black and white dialog appears, type ipconfig. * Your IP address is on the top, next to the name IPv4.
A gigabyte is 1000 megabytes so 16 gig would be 16000 megabytes 16 gigabytes is about 3500 songs, or 20,000 photos, or 20 hours of video
What does CC mean in an email subject line?
Carbon Copy. Sometimes it also refers to what is called blind carbon copy.
It when when you want to send an email to different email addresses.
222 kilobytes is around 0.222 megabytes,since there are 1000 kilobytes in a megabyte. Actually, there are 1024, but we say 1000 as it easier to calculate. I believe this is also the reason why when you buy a 120gb hard drive, you might find theres actually only around 110,000 mb of space on it, since the larger the number the bigger the miscalculation of the extra 24 bits is going to be.
Similarly, there are 1,000 megabytes in a gigabyte, and 1000 gigabytes in a terabyte.
address space=24bits => (2 Power 24)=16M words
When computers and their language was designed, they created "binary" which is the language of 1010111010010001 that you see in advertistements, or reference in text books.
Binary is written in 8 characters. So every binary set you see will always be divisble by 8.
Now, those tiny 1's and 0's are called "bits" and since there are 8 bits to make one binary set, they called that set a "Byte". And since everything is still divisble by 8, one kilobyte is 1024 bytes.
ie.
8
16
32
64
128
256
512
1024
As you can see the numbers are simply doubled. you see these numbers frequently when purchasing flash drives, harddrives, etc.
::BIG EVIL COMPANIES::
Like to steal your money and give you less than what you paid for.
Most companies will define a gigabyte as 1,000,000,000 (1 bil) bytes. That's 73,741,824 bytes less than the real total which means a gigabyte flash drive is actually 954mb, instead of 1024. That's 70mb LESS!!!
Difference between soft copy output and hard copy output?
Soft copy output is the text/graphics that are displayed on the computer screen. Hard copy is the page on which the text/graphics have been printed in a printer and can be held in your hand.
This is actually a very complicated question to answer as there are so many different (and often contradictory) ways to define and measure the speed of a computer. Because of this people often get confused and misinterpret the term. The following answer is obviously incomplete, but should help you understand some of the issues and give you ideas for other information to research.
- clock speed, measures raw clock signal in Hz - easiest to measure but least informative, especially with modern CPUs having multiple heavily pipelined execution units running in parallel
- OPS, measures operations per second - typically a measure of ALU speed only and ignores overhead that can slow speed below this figure (sometimes OPS and IPS are used interchangeably and both mean instructions executed per second, which does include the overhead)
- IPS, measures instructions executed per second - however in CISC computers some instructions take much longer than others to execute while in RISC computers almost all instructions take about the same amount of time, causing RISC computers to usually score higher than CISC computers even if both have similar real world performance
- FLOPS, measures floating point operations per second - for floating point computation intensive applications this gives an excellent measure of the speed, but if the application uses little or no floating point calculations it is useless
- benchmark programs, measures various synthetic but standardized performance parameters - these measurements are usually based on known critical sections of typical real application programs but can be run under more controlled conditions
- application programs, measures real world performance but needs the real application - hardest to measure (especially if the application has yet to be written when the computer must be selected) but it gives the most informative results
