800MHz and DDR2 is the assigned DIMM
There are 1024 Megabytes in 1 Gigabyte. 6144 Megabytes in 6 Gigabyte. Therefore 6 Megabytes equals 0.005859375 Gigabytes.
How good is 2MB L2 cache as compared to 3MB L2 cache?
Larger the size is better but it is hard to know how much better. Read/Write latency (time) is also an important factor for performance.
1,000.
However, since you mention RAM, you probably mean 'GiB' (Gibibyte or 1024 x 1024 x 1024 bytes) and TiB (Tebibyte). In which case, predictably enough, 1,024.
Why is all data scored in a computer in binary form?
I'ts the most efficent method to the technology used today, everything is reduced to a 1 or a 0 which equates to a switch - voltage on or voltage off. A processor is fundementally millions of switches. It more than two options were use for example 10 for binary, a resistor would have to be used instead and the lack of accuracy would cause corruption.
What is one billion bytes called?
1,000 bytes, strictly doesn't have a name. A kilobyte is 1,024 bytes.
However, hard drive manufactures round this down to 1,000 bytes, so you can argue that 1,000 bytes is called a kilobyte.
Hard Drives that are advertised as 1TB drives often only have 1,000GB, not the 1,024GB they should have by definition... Always read the label!
What command reverses the last action or command?
The command is normally called "Undo". It is often located on the "Edit" menu; there may also be a button, often with a curved arrow pointing to the left. Some programs - such as Microsoft Word - allow multiple levels of undo.
Is a disk writer an input or output?
A flexible disk is more usually known as a floppy disc and they were a feature of all early personal computers as larger computers as well. They have such small capacities that they have been replaced by hard disks, optical disks and USB based storage.
The discs were considered to be storage rather than input or output. However, the disc drive that handled the disc can be thought of as an input and an output device.
How do you measure storage or memory size in computers?
There are three types of memory, video, storage and RAM. Storage memory is on your hard drive and is used to store everything that's software or virtual on your computer, such as programs, files, settings, etc. If it's part of your computer and you can't throw it out of the window, it's software. If you throw it out of the window and it comes back, it's a cat. Anyways, video memory is memory that is set aside specifically for usage by your video card or onboard video (this doesn't take any away from your RAM or hard drive). It functions much like RAM. Finally, RAM acts as a scratchpad for your computer, keeping track of everything that's not "finalized" or saved on your hard drive (everything in RAM, by the way, is lost when your computer is turned off). All three are seperate, distinct types of memory, but they are all measured in bytes, kilobytes, megabytes, and gigabytes, or even terabytes! Bytes are the smallest unit of memory. Kilobytes are roughly equivalent to one thousand bytes, about enough to hold one page of typed text. Megabytes are the next biggest amount and, you guessed it, are about equal to one thousand kilobytes. Gigabytes follow in the same fashion (they hold A LOT of information), and so do terabytes. *~Trivia Warning!~*The latin rootgiga means "giant", and tera means "monster"!
So what's good for each type of memory? Ideally, the hard drive should hold the largest amount, followed by RAM and then video memory. Although these amounts constantly change (hey, having 16 MB of RAM used to be impressive), a good hard drive should hold at least 20 GB, probably a lot more if you're into photos, music, and especially videos (some models hold well past 200 GB!). RAM should be at least 1024 MB or above, and video memory varies with what you want to do. If you bought a computer to gun down and frustrate thousands across the globe while making it look like a high quality movie, 512 MB is stellar (even more is probably unnecessary, but FANTASTIC!). However, if you're just using Word, you won't need much at all.
Let's say :
1 bit=1 binary (0s and 1s) digit
1 byte=8 bit
1 kilobyte=1024 bytes
1 megabyte=1024 kilobytes (Sounds like a lot; it isn't really.)
1 gigabyte=1024 megabytes (You could say it's big)
1 terrabyte=1024 gigabytes (Humungous)
In video or tapes, an "exabyte" or "exobyte" is up to about a year straight of recording.
Hope this answers your question thoroughly, and hey, you just might have learned something!
What is the difference between a KB and a GB?
1024 Kilobytes = 1 Megabyte
1024 Megabytes = 1 Gigabyte
1024 Gigabytes = 1 Terabyte
So, 1 GB = 1024*1024 Kilobytes = 1048576 Kilobytes.
Who is affected by computer piracy?
Computer Piracy is usually the distribution of computer software without the permission of the company. The money that would be used for a sale of the commercial copy usually goes to the programmer or programmers of the software. Other who may have benefited from the sales include a range of people depending on the type and scale of the software. For example a video game may include investors, programmers, developers, artists, producers, publishers, distribution, and retail clerks; upwards of hundreds of people who are benefited by the sale of the software.
What does the peripheral device uses to attach to the computer?
Generally USB connectors or serial 29 pin parallel connector is used for this perpose.
What is a mouse and how does it work?
A mechanical mouse has inside of it a ball which comes in contact with the desktop or mousing surface. As the user moves the mouse around on the desktop, the ball rolls with these movements. This rolling is detected by two wheels at 90 degree angles from each other which are positioned in this way so that one wheel can detect up & down movement, while the other detects left and right movement, together they can reliably detect mouse movement in any direction. A third wheel, the guide wheel is spring loaded and presses the ball against the two sensor wheels.
What happens when you merge cells?
When you merge a cell, the effect produced depends on the way the cells were merged. If it is a parallel connection, the cells functions as a single cell but if it is in series, they will combine their strength.
What are the computer measurements for bits bytes etc.?
Bit= a single 0 or 1,
Byte= 8 bits (any combination of 8 0's or 1's)
Kilobyte (KB)= 1024 bytes
Megabytes (MB)= 1024 KB
Gigabyte (GB)= 1024 MB
Terabyte (TB)= 1024 GB
Petabyte (PB)= 1024 TB
Exabyte (EB)= 1024 PB For a detailed answer cut and paste the following URL in your browser : http://www.smartftp.com/support/kb/bits-bytes-mega-giga-tera-f53.html

What is cell references for the rightmost cell in row 32 in a worksheet?
Excel 2007 = XFD32 (16,385 total columns)
Excel 2003 and earlier = IV32 (256 total columns)
What is the difference between clip art and images?
Well, clip art usually refers to stock images created to be freely used in any document, so graphics art can refer to any type of graphic, while clip art is specifically those stock little images you see in Word doucments.
What does a concept map look like?
A concept map is a diagram showing the relationships among concepts and processes.

What does it mean that a processor is Dual Core?
A dual-core CPU combines two independent processors and their respective caches and cache controllers onto a single silicon chip, or integrated circuit.
http://en.wikipedia.org/wiki/Dual_Core_Processors
-DJ Craig
:
A dual core processor is a CPU with two separate cores on the same die, each with its own cache. It's the equivalent of getting two microprocessors in one.
In a single-core or traditional processor the CPU is fed strings of instructions it must order, execute, then selectively store in its cache for quick retrieval. When data outside the cache is required, it is retrieved through the system bus from random access memory (RAM) or from storage devices. Accessing these slows down performance to the maximum speed the bus, RAM or storage device will allow, which is far slower than the speed of the CPU. The situation is compounded when multi-tasking. In this case the processor must switch back and forth between two or more sets of data streams and programs. CPU resources are depleted and performance suffers.
What is a internet service provider?

There are many in the world, depending on your location. ex. Verizon, Road Runner, NetZero, AOL, Time Warner, all these plus many more companies provide Internet access in the USA.
