For addressing 1 MB memory, the number of address lines required,?
83474
Each bit of memory can address 2^n (2 to the nth power). So 1 bit can address 2^1 = 2 bytes. 2 bits can address 2^2 or 4 bits (0, 1, 2, 3).\n\nSo 20 bits can address 2^20 =  1,048,576 bytes (or words of memory to be precise; I've assumed you have byte-size memory as is common).

It all dependes on the type of ram you're looking for,\ngo to this link http://www.crucial.com/ , use the memory advisor tool, it will tell you exactly what type of memory you would need for your system. Once you have that information just go online (www.newegg.com my favorite) and order the ram you need.

no , you actually need 4 256 mb ram to equal 1gb ram

I think yes...\nBecause in my view as the address are in 32 bits so maximum size it can refer will be 2^32 that is 4 GB.

If you can format 128Gb, your BIOS likely already supports LBA (Large Block Addressing).\n\nSounds more like you are trying to format it using FAT32.  FAT32 only partitions/formats up to 128Gb.  NTFS will handle up to 1.6Tb, so if you're using Win2000 or WinXP, use NTFS.  Otherwise (as already suggested), you'll need to partitioning.

Go to:\n\nwww.kahlon.com\n\nThey have an excellent site for finding out exactly what your computer needs in the way of memory.  They've also got some of the cheapest prices on the net.\n\nYou can find out what you need and then comparison shop at:  \n\nwww.newegg.com\nwww.tigerdirect.com\nwww.ebayexpress.com\n\nI think you'll find that 1GB laptop RAM will run around $100 at some of the cheaper sites.

go to your manufacturers website, or the website manufacturer of the motherboard, and enter the model number and search for specifications.  It may also be in your manual.  Today's comptrs usually take 4gb RAM.\n\nYeah if u just want to know what u got now do as above.  What I've said is to give u the maximum capacity.

Threads share a virtual memory mapping, so switching between them does not invalidate the TLB and creating them does not require marking pages copy on write. \n\nDue to the lack of an expensive TLB flush, switching between two threads in the same virtual address space will be quicker then switching between processes (which by definition have separate address spaces and thus require the TLB flush).\n\nThe exact details vary depending on OS and processor type, but the above is more or less correct for X86 style chips running a 1:1 threading model. \n\nRegards, Dan.

Sounds like an all to common memory issue.\nTry Memtest86: http://www.memtest86.com/

You can Google the Manufacturer and code printed on the stick.  This looks out of date but may help...\n\nFor 72 pin modules you will see something like \n\n1 x 32-60 \n2 x 32-70 \n4 x 36-60 \n8 x 36-70 \n\nJust like the 30 pin modules, the first value represents the size, EXCEPT it only represents ¼ of the total memory size. Don’t ask why, just accept it. So the value of 4 represents a 16 MB (4 x 4) module. A value of 8 represents a 32 MB (4 x 8) module.\n\nThe second value, again just like the 30 pin, represents parity and the number of pins. 36 is used for parity and 32 for non-parity. You aren’t asking why again, are you?\n\nThe third value represents the speed, the same as the 30 pin.\n\nLast option is put the stick's in one at a time and let the BIOS figure it out on boot up.

Amount of memory (RAM) would be important in your case, 1 GB should be sufficient all though anything more would be noticeable. A high CPU speed would also be helpful as would a large hard drive.

Some of these answers are wrong and others are not clear enough.\n\nYou need to first check with either the PC maker or motherboard manufacturer and see:\n\n1. What is the total amount of memory supported by the board?\n2. Does this memory have to be installed in pairs?\n3. What type of memory am I currenty running so I don't break Double DDR by installing a single DIMM\n\nBasically your usually better off with multiple chips rather than a single large chip. Your cost per MB is usually lower this way plus if the system is designed to use multiple channels you get added bandwidth by splitting the memory into seperate banks on seperate busses.\n\nCrucial has a pretty good web site for finding out what memory your system can take but don't take that for gospel.

you can put two 512mb ddr-266 dimms for a total of 1 gb pc2100 memory

Memory Type\n DDR400/333 SDRAM\nMemory Description\n Three DDR 2.5V DIMM sockets support up to 3GB with 266 memory setting. PC3200/PC2700/PC2100/PC1600 non-ECC, unbuffered DDR SDRAM memory

Get 512 Mb, or more if you can afford it.   Ideally you want to the the memory on 1 stick, not 2, to conserve the slots on your motherboard for future upgrades.   Be sure to buy the correct type of RAM for your motherboard.
