Computer Memory

The entire point of a hard disk is that nothing happens to your data when it's turned off. Data is stored by magnetizing tiny areas of the surface of the disk. They don't need electricity to stay magnetized.

There are two definitions. The official definition says: * 1,000 × 1,000 bytes (B) = 1,000,000 B = 1 megabyte (MB) * 1,000 (MB) = 1 gigabyte (GB). This is the definition used for hard drives, DVDs, networking, and everything else. There is also another definition based on 1024 instead of 1000, so 1,024 "megabytes" are equal to 1 "gigabyte". These are used for memory. These are more correctly referred to with MiB and GiB instead of MB and GB: * 1,024 × 1,024 B = 1,048,576 B = 1 MiB * 1,024 MiB = 1 GiB

Hard-drives store large amounts of data for extended periods of time. RAM stores smaller amounts of memory only while it is needed. Data stored in RAM can be accessed much faster than data stored in hard-drives. This is necessary because the processor can only interact with a few numbers at a time. An example might be when running a game - all the most necessary game data is loaded from the hard-drive into RAM. Then, as the game runs, the processor rapidly pulls small bits of data from RAM, performs calculations, and then quickly passes it back. The results are then displayed (through the video card) on the screen.

L1 and L2; Many years ago L1 was the only cache memory integrated into the CPU (processor) and L2 had to be added to the motherboard. Currently (as of year 2013), CPUs implement both L1 and L2 cache in the casing of the processor. Thus, processors (CPUs) ship with amounts of L2 cache independent for each processor core.

CMOS is a small component cluster on a computer motherboard which hold a very small amount of simple information. It has a large button battery which supplies the needed power to preform one of its main functions: Keep date and time. It also holds vital system settings.

Basicly, It is a small memory componant, but users can not store data on it aside from system boot settings.

Yes, you can use different speed DDR2 RAM, but the faster one will be clocked down to the speed of the slowest one, so your not taking any advantage from the faster speed of one of those...however, this mix can probably cause instability (not in all cases), so if you can, get the RAM at the same speed :)

if you are talking about ram then all information get lost when you turn off computer. in case of rom, the information is permanent until we erase it forcefully..

It depends on the motherboard. If you can find out what type of motherboard you have, you can look up what type of memory and how much of it you can install into the memory banks. Keep in mind that the operating system that you have may limit how much of the installed memory you can actually use.

A gigabyte is bigger.

1Gigabyte = 1024Megabytes

The most important thing to do is to ground yourself before handling the RAM. To do this touch a metal part of your computer. This will ground you. Alternatively you could wear an anti-static wrist band which keeps you grounded at all times.

If you had to choose one then you would chooes SDRAM. it is faster than EDO

C: is most common.

Disadvantages of DRAM

Dram having have access time compared to SRAM.

It needs extra circuit to refresh the cell which refreshes the Dram thousand times per second. So it requires more power.

ram is primary storage

first, download firefox n then download user agent switcher 0.7.3 add on. go to tools scroll down to default user agent n change it to iphone 3.0 after that go to iphone.airg.ca...ul be asked u 4 yr phone #, jst type it in...they will then send u a code and a link to yr phone. dnt type in the code...type the link into yr computer browser just as you see it on the phone. u will then be able to access airg. this however will not help u to log in into an old profile

DDR and DDR2

English obviously isn't your first language. If you mean "Which is more, a megabyte or a terrabyte?" then the answer is a terrabyte. There are 1024 Bytes in a Kilobyte, 1024 Kilobytes in a Megabyte, 1024 Megabytes in a Gigabyte, and 1024 Gigabytes in a Terrabyte.

random access memory

it called bootsector

after POST boot sector is write in address 0:7c00

boot sector for running have a signature ,in its 510 th address it shoud have 0xaa55h

A motherboard nomally has slots for the addition or replacement of RAM modules. The particular type depends on the type of board. The manufacturer website or a memory manufacturer website can help you find out.

If you want to find this out without opening the case on desktop or laptop go to the crucial memory website and download the scanner tool. The Crucial System Scanner automatically analyzes your computer memory information and suggests an upgrade that's guaranteed compatible.

The processor registers! Relatively, they are very small (a register on an Intel 32-bit processor is only 4 bytes large!) but they are very fast. Programs use them to store the part of data they are working on and some memory addresses.

A cell phone text message is 140 or 160 bytes based on service provider.

As for a text page. A single letter is 1 byte. So it depends on paper size etc.

True.
