Computer Memory

None!

Or you can take all disks out or they can be broken

So always back your work up!!!

The Compaq SR1940IL supports a maximum of 2 GB of RAM, using two 1 GB modules of DDR2-533 RAM.

Petabyte (1,000 terabytes;) then exabyte (1,000,000 terabytes.)

Most desktops and notebooks use one of the three most popular types of synchronous dynamic random access memory (SDRAM) for the main system memory. Single data rate (SDR) SDRAM is the older type of memory, commonly used in computers prior to 2002. Double data rate (DDR) SDRAM hit the mainstream computer market around 2002, and DDR2-based systems hit the market in mid-2004.

DDR SDRAM is a straightforward evolution from SDR SDRAM. The big difference between DDR SDRAM and SDR SDRAM is that DDR reads data on both the rising and falling edges of the clock signal, so the DDR module can transfer data twice as fast as SDR SDRAM.

While DDR has a limited clock rate, the evolutionary changes to DDR architecture enable DDR2 to achieve speeds beyond of DDR, delivering bandwidth of 5.3 GB per second and beyond! Because DDR2 is able to operate with faster bus speeds, your memory doesn't hold back the performance of your processor.

Generally speaking, motherboards are built to support only one type of memory. You cannot mix and match SDRAM, DDR, or DDR2 memory on the same motherboard in any system. They will not function and will not even fit in the same.

NO that is ROM

No such thing. The next unit up from terabyte is a petabyte, which is 1,000 terabytes.

As of 2013, the DDR3 Sdram, 2 GB, Dimm 240-Pin, 1333 Mhz, Ecc is the fastest being sold today. However, when it comes to computer components, the fastest DDR3 DIMM today may not be the fastest next week.

This depends on the design of the motherboard. Check the manual to find out the required configuration for your motherboard. If you do not have access to the manual, then experiment with different configurations to see what will work. You most likely will not cause any damage to the motherboard. If you insert one stick of memory in slot 1 and it does not work, try installing a second to see what happens. If the memory slots all are the same color, you usually only need to fill one slot at a time. However, if the slots are different colors (blue or white) then you usually need to install the memory in matching pairs.

It depends on the size of the spool or cartridge. Some cartridges are smaller than a standard audio cassette tape, while others are over twelve inches in diameter !

Hunh? The Internet doesn't byte ! What are you inferring, my friend ?

1.Go to Control Panel from start or from My Computer. 2.In Control Panel goto Accessibility Options. 3.Then on left side of the window opened in See also options click on On-Screen Keyboard. 4.By clicking on that on screen keyboard will be appeared on screen

A memory cache is small amount of RAM that is much faster than the rest of RAM?

There is no specific, fixed, area of memory that a driver is stored in (this is handled by the OS as it is loaded) - However in Windows there is specific location in the file system where the device drivers are placed, this is C:\Windows\System32\DriverStore.

A font file generally takes 50-100 kb. It can be more depending upon how funky looking is the font.

ugh i am taking virtual keyboarding too

Yes ram does not differ from manufacturer to manufacturer.

usually you don't need to set any jumper settings in ddr or sdr. but if you wanna over-clock your motherboard(and it doesnt have voltage settings in its BIOS interface) you can set it by jumpers. you'll need its manufacturer's manual though. if you don't have that then atleast name of the manufacturer and motherboard's model number to look it up over the internet. crank up the ram voltage step by step.

and if you're talking about clock frequency then you might be using a PC older than a P3. P3s don't run ddr. and in sdr they have 100 and/or 133 mhz clock speed. you'll need to know which ram you've got than cross reference that on your motherboard's maunal.

any how i need more information for a proper answer.

DDR is the incorrect answer, RAMBUS ram is the correct answer.

• removable solid state disks (e.g. USB Flash drives)

In order to interface more than 64K of memory using the 085, you would need an external address register, perhaps maintained by the 8255, which contained an offset register for part of the memory address space. This would be similar to how the 8086/8088 processors implemented expanded memory before using the 80386 and above processors.

The mental processes that enable us to acquire, retain, and retrieve information

No. However there are forms of ROM that can be changed, like Programmable Read Only Memory (PROM) and Erasable Programmable Read Only Memory (EPROM).
