What is the maximum amount of RAM supported by a Dell Optiplex GX110 desktop?
The Dell Optiplex supports a maximum of 512 MB of RAM using two 256 MB PC100/PC133 SDR SDRAM modules.
Differentiate between static ram and dynamic ram in tabular form any two differences?
· Static RAM: No refreshing, 6 to 8 MOS transistors · Dynamic RAM: Refreshed periodically, 3 to 4 transistors. · Static ram is more reliable · Dynamic ram is less reliable · Static ram is more expensive · Dynamic ram is less expensive · Static ram can store its data when computer is turned off · Dynamic ram looses data when computer is turned off. · A static memory cell takes a lot more space on a Chip than a dynamic memory cell

What is a flash memory camcorder?
Rather than storing all of the files to an internal hard drive a flash memory camcorder is a camcorder that stores all of it's files on a memory card.
Short for programmable read-only memory, a memory chip on which data can be written only once.
Once a program has been written onto a PROM, it remains there forever.
Unlike RAM, PROMs retain their contents when the computer is turned off.
The difference between a PROM and a ROM (read-only memory) is that a PROM is manufactured as blank memory, whereas a ROM is programmed during the manufacturing process.
To write data onto a PROM chip, you need a special device called a PROM programmer or PROM burner.
The process of programming a PROM is sometimes called burning the PROM.

How does a computer programer idenify a particuler part of the memory in a computer program?
Each part of the computer memory - each byte, in modern computer architectures - has an associated address, a number. Usually the programmer will be programming in a high-level language, which, instead of accesing memory directly by its address, uses a symbolic name - called a variable - to refer to this address.
It is up to the programmer to give variables their names. The programmer should try to keep these names meaningful. If the programming language allows longer names, don't abbreviate variable names to one or two letters.
Do current processors have L1 and L2 caches?
l1 is in motherboards l2 is on processor newer processor has l3 too
How can you tell how much memory is in a laptop?
you can enter the CMOS setup or BIOS setup during the post. usually it's in the processor category. or you can check what processor model and speed you have and check on its manufacturer website.
or you can download cpuz at www.cpuid.com , this one checks most of the hardware specifications of your unit.
Does the maximum RAM depend on the processor?
The maximum amount of RAM supported by a computer depends on the processor and the motherboard.
What do SIMM and DIMM banks look like?
The banks themselves don't really look all that different. It's usually better to research the make and model of the motherboard to figure out what it has.
The modules themselves are easy. DIMMs have their RAM chips on both sides, whereas SIMMs are only blessed with RAM chips on one side.
In reality pretty much every motherboard made within well over a decade only has a DIMM memory bank, so it may not be worth your time or energy trying to find out if the motherboard you have has SIMM or DIMM banks. It's almost guaranteed to have DIMM.
DIMM: Dual Inline Memory Module
SIMM: Single Inline Memory Module
What are three considerations when choosing memory?
Speed, memory type (DDR2, DDR3 etc), and capacity.
The 2.5TB system is "the largest SSD installation in the world by far, without question", the executive VP for TMS, Woody Hutsell, told Techworld. The previous biggest one was under 500GB, he told us. At 2.5TB, it is roughly 10,000 times the size of the RAM in your PC
Can you upgrade the speed of your RAM to a higher one?
Yes. loimited by Motherboard chipset - check out the specs for your mobo at Tom's hardware or similar site.
Do Video cards often include their own RAM?
Yes, video cards include their own RAM, called video memory.

What is the use of chip inserter in computer?
There is really no use to your your normal PC user. These tools are meant for people who build their own logic boards, or maybe want to remove chips from an burnt out board and place them on another board. They apply even pressure when inserting the chip however most people do not use them.
What makes cache memory quicker than DRAM?
Cache memory is stored on the processor. Dram memory is stored on the ram chips. It is analogous to having papers on your desk and having papers in the file cabinet across the room. You can get to both but you can get to the papers on your desk a whole lot faster.
What is purpose of the mysqldump program?
it is used to dump table structure and content in text format
Does virtual memory lie in CPU?
Virtual memory refers to the combination of your "physical memory" (RAM) and any available "swap file". A swap file is a chunk of your hard drive that the computer sets aside in case your RAM fills up and it needs somewhere to store some extra information temporarily (however swap files tend to be a bit slower as they use a hard drive rather than RAM).
So if you had 2GB of RAM on your PC and Windows made a 2GB swap file, you would have 4GB of virtual memory.
What measures the time required to deliver an item from memory to the processor?
chronological base of classification of computer
