Why flash memory is non volatile in nature?
Flash memory is what is called RAM/ROM it is both RAM ( Random Access Memory ) and ROM ( Read Only Memory ). Flash memory can be used to store data, but has a limited number of writes before the memory "forgets that it exists."
ROM is the same thing as a hard disk's memory. It's in a solid state when the power is off. ( Stored as a magnetic charge. )
What is Difference between internal ram and external ram in 8051?
Internal Ram in 8051
the 8051 includes a certain amount of on-chip memory. On-chip memory is really one of two types: Internal RAM and Special Function Register (SFR) memory.
External Ram in 8051
As an obvious opposite of Internal RAM, the 8051 also supports what is called External RAM.
As the name suggests, External RAM is any random access memory which is found off-chip. Since the memory is off-chip it is not as flexible in terms of accessing, and is also slower. For example, to increment an Internal RAM location by 1 requires only 1 instruction and 1 instruction cycle. To increment a 1-byte value stored in External RAM requires 4 instructions and 7 instruction cycles. In this case, external memory is 7 times slower!

How do you disable an internal component in a notebook computer?
You do it in CMOS setup, usually by pressing F2 during bootup, but the exact key combination varies from device to device.
How do I upgrade my Seanix desktop computer's ram?
Run Belarc Advisor to find out what kind of motherboard you have. Then Google it to find out what the maximum RAM it will accept both per-slot & overall. From there, it's just a case of order it & put it in.

By transferring data on both rise and fall of the clock signal
Good in what? 128mb is great in certain equipment, but not enough to even start to run other types of equipement.
Try re-posting with more information about what you have the memory in.
What are Programs stored on rom chips are called?
Programs stored on ROM chips are called firmware. The motherboard stores the keyboard controller support program on the ROM chip.

How you can convert your flash memory drive from RAW to fat or fat32?
to access your flash drive you should be able to open my computer and then listed with the drives should be your flash drive you can just right click and then go to open. However, if this does not work do the following to convert to FAT or NTFS:
To convert a volume to NTFS or FAT from the command prompt
Open the Command Prompt window.
In the command prompt window, type
convert drive_letter: /fs:ntfs
For example, typing convert D: /fs:ntfs would format drive D: with the ntfs format.
Notes
To open a command prompt, click Start, point to All Programs, point to Accessories, and then click Command Prompt.
You can convert FAT or FAT32 volumes to NTFS with this command.
Can you use a 60ns memory instead of 70ns memory?
60 ns is faster than 70 ns. the smaller the speed rating, the faster the chip
What will happens if you put a DDR400 Memory in a DDR333 Maximun DIMM?
Your motherboard might be able to 'clock back' the DDR400 to DDR333. This means that the DDR400 ram will reduce it's clock speed to DDR333 to be compatible. Not all motherboards support this though.
That model is officially supported up to OS X 10.3.9 (Panther) It supports OS 9, 9.1, 9.2, 10.0, 10.1, 10.2, and 10.3 10.4 can be loaded via Xpostfacto (a hack), but the lack of a DVD drive or firewire makes the installation difficult (not many 10.4 install CDs floating around). With 320MB RAM, it should run 10.3.9 OK (assuming it has at least a 6GB HDD). Note that if the hard drive is greater than 8GB, OS X should be on a first partition of less than 8GB.
Why cash memory is faster then main memory?
Primary memory is faster to access because it is wired directly to the processor. It is used by the system to perform operations while programs are running. Examples are cache, RAM, and ROM.Secondary memory is usually somewhat slower and is used for permanent storage of information. Examples are hard disks, floppy disks, CDs, DVDs, flash memory, etc.
