How many byte in megabytes?

There's 1024 bytes in a kilobyte, and 1024 kilobytes in a megabyte. Therefor there are 1048576 bytes in a megabyte.

Opposite to Random access memory?

Sequential access memory. Typically implemented with long shift registers, acoustic delay lines, or fixed head magnetic drums/disks.

Why do the computers get slower when they get older even when you format them?

It's not about computers, it's about software which requires more and more computer resources with each release.

What option interfaces with the memory controller chip to get lines of code into the CPU?

Pre-fetch - a component of the pipeline interfaces with the MCC (Memory Controller Chip) to get lines of code into the CPU

A laptop with 4GB ram with 1.8ghz and 667MHz or a laptop with a 3GB ram and a 2.2ghz and 800MHz which would be faster?

If they both have the same Intel then I think that you should get the second laptop, th Intel with a laptop can effect the speed greatly, the more the cores in a laptop the better and faster your laptop will be.

Why computer memory is in multiples of two?

If you are referring to how the numerical amounts assigned to computer memory (RAM) are always divisible by two, it is because we use a Base16 system in computers.

At the lowest level everything breaks down to Binary code. Binary consists of only 2 characters 0, and 1. A single binary digit is referred to as a 'bit'. The next step up is grouping 8 bits together, which makes a byte. The next step past that is exactly 1024 bytes, which makes a kilobyte.

So RAM is a volatile storage for binary data, so its storing these 0's and 1's, which are equally portioned, therefore the RAM must follow the same numbering convention.

A hard drive stores data on?

hard disk save data on platters. On platters there are tracks and sectors in which the data is saved.

How do you clean up your computer to get more MB?

Answer

1) Clean up your Start Up section Stop all unnecessary programs from running at startup. There is no need to have any IM program running if you are not using them. Also stop loading from bootup programs that you only use sporadically Go to Programs>Startup Delete the icons --they are only shortcuts, not the programs.

2) Close unneccesary programs On the bottom right of your screen you will have all programs that start from bootup. Right click on any program you do not use and find a way to stop it from loading on startup (usually under options or preferences).

3)Run Disk Cleanup and Disk Defragmenter that you find on your computer at Programs>Accessories>System Tools>. I recommend that you restart your computer before doing this to be sure that everything is closed - it is more convenient.

4) If the Internet is slow, delete the browsing history: In the Internet: History>Clear Recent History or Tools>Delete History. Make sure cookies is included in the items you delete, along with temporary files.

5) If you have had the computer for some time and this has just started after you have added software, you may have exceeded the capabilities of the memory on your computer. You might buy more memory since memory is cheap these days. If you can spare $30-50 then you can upgrade your memory. This will get you the most performance gain. Make sure you know the memory type your motherboard will support before you purchase memory--you need slots to install the memory card. You may need help on this step--

3) CAUTION: Download a program You can find programs at download.com that will help to optimize your system (memory, registry, etc.) Check out the reviews and download one that has a free trial. If you like it you can buy the program. Some of the free trials limit what is available unless you purchase the full version.

5) Change the MB settings for memory speed You can jack up the speed at which your memory is accessed, although I do not recommend novices trying this. Doing this could burn out your memory.

What games run on 1.50GHZ 504 Mb of RAM?

How do you load something on your computer when you have no memory?

If by memory you mean RAM then you might be able to boot into a live CD and then perhaps use virtual memory from a hard drive?

Is Cache memory a form of ROM?

No. It's a kind of RAM integrated into your processor. The cache memory is usually small and is used to store data that is being used by the processor because accessing the main RAM directly will be slower.

In multiple-processor systems, a problem called cache incoherence can occur when two or more processors access the same region, modifies the data in different ways and not immediately writing back the data to the main RAM. It will cause two different versions of the same region existing simultaneously, causing problems. That is why mutexes or other locks should be used when accessing shared memory.

What is a good GB for RAM?

For WindowsXP, 1GB or more.

For Windows Vista and Windows 7, 2GB or more, with 4GB+ being optimal.

SODIMM in computer memory?

SODIMM is small size memory for laptops.

Is a 256mb memory in a video card a considerable amount of memory to run a high end PC game?

No. Unfortunately most of the new games, such as prince of persia, assassin's creed, etc require at the least 512 MB card.

How do you turn off bookmarks?

This is not possible, though it might be possible to hide them or just ignore them.

Why dedicated system memory is 0?

All computers start counting at 0, not 1.

How much GB of ram is 261664 kb of ram?

That's less than 0.25 GB. If you use SI units, that's little more than 0.26 GB.
