Computer Memory

There are several ways. One of them is to use software such as tweak, all kinds of optimization software (for instance jv16) which are able to clean the registry and do defragmentation of it. Also you need to defragment all your hard drives periodically (once per month or more often depending on how often you modify/copy/delete data).

You can use also hardware tricks like overclocking. Also to make an upgrade might a good idea if your computer is rather old or lacking power. You might need to add some RAM, replace the system hard drive with a drive with better performance. You might consider upgrading the CPU (if the motherboard supports newer CPUs). Also the video card might cause some discomfort especially if you are working under Vista.

"Compaq Presario" is the name of a line of computers. It does not refer to any specific model. Without further information, no advice on whether or not it is compatible with your computer can be given.

The size of the picture can be very small (on the internet, many pictures are from 10 to 500 kilobytes). On the other hand, however, pictures from a digital camera are much larger. Many older digital cameras take pictures less than 1 megabyte (1000000 Bytes). The latest cameras can take pictures around 3 and 4 Megabytes.

Ddr stands for double data rate. Which actually doubles the speed compare to sd ram

RAM - is a temporary storage area for the computer to use. However - once the power is switched off - the RAM memory is erased. Therefore - any programs and data are stored on the hard-drive.

It is called random access memory (RAM), or simply memory.

DDR Memory is sometimes sold in pairs, for those setting up dual channel systems.

Dual Channelling sorta like setting up a RAID array of RAM.

Note that RAM labelled as being dual channel isn't any different then regular RAM its just two sticks of the same size.

that's all :)

Some memory used in dual channel boards do not behave well when paired with other brands sometimes they do not even behave well when paired even with same brand and model. Paired DDR RAM assures the user that it has been tested by the manufacturer to behave well.

The modules aren't just the same size; they are also the same speed and latency rating. Typically the chips are the same production batch and that increases the likelihood that the paired modules will work approximately at the same speed, therefore being detected (and usable) as dual-channel.It's like a cross-country trip with two cars - if car A is a performance car driven by an aggressive driver and car B is an econobox driven by a little old lady, then A can go no faster than B if both are to arrive at the same destination at the same time. If B is too slow, A may just sit and wait at the destination for a few days - you've essentially dropped into single channel mode performance, and the bios will usually detect this significant of a difference and not allow dual-channel mode.

second answer is not correct, it does not matter who makes the ram chip, it all works correctly together, but buying dual channel set is cheaper, what im about to write is where 2nd answer is *confused* at. If you have 2 ram chips same size but diffrent speeds say one is 555 and the other is 667 then the one that is higher has to lower its performance to match the 555, which takes away from the available ram on the computer. thus buying dual channel kits saves you both money and lets you keep the amount of ram you have installed, i currently have 4 gigs installed, 4 1gig sticks, 2 are 555's 1 is 667 and the other is 800, which after matching the 555's i have 3.25 available.

There is no CD-RAM, because there is only CD-ROM for forms of cds, instead the application that the CD runs would be using RAM so that is the closest thing to the existence of CD-RAM.

The L1 and L2 caches (the "CPU memory") are already being used in a manner similar to RAM. L1 and L2 cache acts as a sort of buffer, so that the CPU does not have to fetch data from main memory as often, which slows the computer down. This, the fact that the circuitry to use the caches as main memory isn't available on most motherboards, and the fact that CPU caches are simply not large enough to run a modern operating system, make this both impossible and impractical.

A byte is the smallest data unit of modern binary computers. It represents either a 1 or a 0. Bits are compiled into a set of eight bits, known as a byte. Bytes represent one piece of data, such as a single letter, etc.

There is the byte, kilobyte, megabyte, gigabyte, and terabyte.

A byte is just 8 bits, 8 "binary digits", which can be anything from 0000 0000 to 1111 1111 (which is 255 in base 10).

A kilobyte is 1024 bytes.

A megabyte is 1024 kilobytes.

A gigabyte is 1024 megabytes.

A terabyte is 1024 gigabytes.

There are other prefixes, but they are not commonly used outside of supercomputer environments.

that's true! ...and NON-volative, by contrast, does lose its contest when the power is removed from the computer.

non volatile (ie permament storage after power down) storage components are a DVD/CD or Hard Disk Drive

RIMM is more expensive and less popular because of how old it is.

A megabyte is 8 times bigger than a megabit. 8 bits = 1 byte.

# 4 DDR II DIMM memory slots (supports up to 4GB memory) # Supports 1.8V DDR II DIMM # Supports dual channel DDR II 667/533 DIMM # DDR2 PC5300/PC4200

# 512MB or 1GB Modules # Install like memory in each channel for Dual Channel operation # If only 2 DIMMS installed, place in same channel (slot color) for Dual Channel, if installed in adjacent slots, memory will run in single mode.

Sorry sir i don't no.

SDRAM

You are running two programs at once that require 10 megabytes each on a computer that only has 16 megabytes of RAM. What makes this possible?

Max length of memory segment =4GB

there r 8KB number of descriptor in GDT and 8KB in LDT . So total numbr of descriptors=16KB

4GB*16KB =64TB

thay are mesured in MHz (megahurtz)
