Computer Memory

The hard drive in a computer system will hold the most information.

thay are mesured in MHz (megahurtz)

Most current motherboards are using DDR3 SDRAM, although new higher-performing motherboards are starting to appear which use DDR4.

Registers

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?

Typical plattered hard drives can be found in capacities of a few Terabytes at most. We are running into space limitations because the current platter system cannot handle much more than this anymore.

Sorry sir i don't no.

yes but not all of it is accesible

SDRAM

You can find out how much RAM (memory) is on your computer by checking the System Information dialog box to see the installed physical memory, or you can go to Control Panel. The amount of RAM you need depends on the operating system you are using. You also should consult your owners manual which will show you the number of slots on how much RAM it will accept.

Memory hierarchy measures a computers performance issues. A general hierarchy would reflect the following. Internal ; processor registers and cache, main; ram and controller cards, on-line mass storage and online bulk-storage.

3072 is how much memory the ram has and what ram does is it like short term memory so when you are using any program it is using ram.

ddr3 is the type of ram, it just means it is a little better then ddr2.

yes

if you have installed two 512 MB of ram, then it could be due to ram slot. may be your one ram slot is faulty.

Computer memory stores information as a binary representation (1/0) so the smallest unit of storage is the single "bit". However, when talking about storage people find it more useful to use the term "Byte" which is a unit of 8 bits.

When talking about volumes of storage the convention is to then prefix the word "Byte" with the SI, metric nomenclature denoting magnitudes.

Kilo (1000) (kB)

Mega (1000000) (MB)

Giga (1000000000) (GB)

Tera (1000000000000) (TB)

Peta (1000000000000000) (PB)

Exa (1000000000000000000) (XB)

Zetta (1000000000000000000000) (ZB)

Yotta (1000000000000000000000000) (YB)

It will "use" as much as you can give it. For a desktop installation, you will need at least 128 MB of RAM.

P.S. Ubuntu 5.10 is long obsolete. There is absolutely no reason to use it other than historical curiosity.

Think of a computer as a person who's doing paperwork on a desk. Now, increasing memory increases the size of the person's "desk", or the total working space of your computer. It doesn't make the person (or processor) actually working faster, but it does give it a bit of relief if there are a lot of papers (or running applications)

The size of the memory itself does not really change the speed of the computer unless demanding applications use it all up, at which point the rest of the memory is taken from the hard-drive, which can impact performance since hard-drive are usually very slower than RAM.

Now, the speed or clock of RAM does have an effect on processor speed, as it determines how fast can the CPU transfer data back and forth to the memory.

If the RAM is slower than the rate recommended for a given CPU and motherboard, it will very likely impact performance, as the RAM will not be able to keep up with the CPU, and that'll cause slowdowns.

A copy command for the computer is a function that lets you copy a photo or text. Once copied this photo or text can be pasted elsewhere.

Yes, absolutely because DDR rated for higher frequencies are also backward compatible. Just pay attention to the DDR generation because you DDR-I is not compatible with DDR-II.

[1] the accumulator is meant to be an operand. so there is no requirement for the operand address field for one operand in the instruction. this results in short of CPU supports zero address instructions. Normally CPUs have two types of instructions:

1)zero address
2)single address

the single address instruction have one operand in main memory and the other in accumulator.

[2] instruction cycle takes less time. it saves time in instruction fetching due to the absence of operand fetching due to the absence of operand fetch.

Memory modules that utilize temporary storage areas (known as buffers) to help manage the data sent to the memory by the memory controller. Buffers act as current regulators keeping the amount of current flowing to and from the chips at optimal levels. The purpose of this is to allow for more memory chips on modules by keeping the memory from being overloaded by the chipset. It can also be used to allow more modules to be used in the system. Not all systems can use buffered memory; the type of memory required is dependent upon the computer's memory controller.

Buffered memory is an older term for registered memory.

However, some new large systems use "fully buffered memory". In normal registered/buffered memory only the control lines are buffered, in fully buffered memory the data lines are buffered as well.
