Computer Memory

N as they come with the memory already sized, you would have to purchase a larger memory card.

Bit (b) and Byte (B) is entirely different. Bit is the smallest storage unit in computer science.

8 Bit (8b) = 1 Byte (1B)

In normal working, when you press any key, it covers atleast 1 Byte of space. Means if you will type ABC, it will cover 3B, so that we consider byte as a smallest unit of useful data.

If the number of contacts on the memory capsule is the same as the number in the socket there is a chance that they are compatible but there are a great number of different pieces of hardware that look similar but re not. Consult any documentation (also forums on the Internet - search for your computer name or the motherboard identity)

1 terra=40giga bytes

corrections...

There are 1024 gigabytes in a terabyte.

1 bit (binary digit*) = the value of 0 or 1

8 bits = 1 byte

1024 bytes = 1 kilobyte

1024 kilobytes = 1 megabyte

1024 megabytes = 1 gigabyte

1024 gigabytes = 1 terabyte

1024 terabytes = 1 petabyte

(Yeah right! Is there a hard drive big enough?)

DDR is not as fast ad the DDR2 ans that is the main difference.

Random Access Memory (RAM) is typically made up from an array of cells arranged in rows and columns. Each cell represents one bit and each has a transistor and a capacitor. The capacitor can store an electric charge and if the charge is above that of a control level, the cell is set (denoting 1), otherwise it is not set (denoting 0). The transistor is used to both fill and drain the capacitor to switch its state. The control level is typically 50% of the capacity.

However, the capacitor is like a leaky cup -- the charge will quickly drain away within a few milliseconds. Thus the RAM must be refreshed thousands of times a second to ensure no set bits fall below the control level. RAM with a refresh of rate of 100 nanoseconds take 100ns to refresh every single bit. During a refresh cycle, if a capacitor is above the control level then it is immediately refilled, otherwise it is allowed to drain completely.

To access any bit of memory, a row address selector (RAS) selects the row while its associated column address selector (CAS) selects the column. RAS/CAS is used to both read and write bits. By selecting successive columns along the same row, groups of bits can be read in quick succession, thus making it possible to read or write 32-bit or 64-bit values at a time, depending on the architecture.

No it is not recommended. Always keep a VRAM. The system very often expects it to work properly as you never now how much memory a program might use. Some operating system (like Linux) can surely cope without it but it is not recommended. Actually, it is impossible to disable virtual memory in any modern system. You can disable the pagefile but this will not disable virtual memory. Virtual memory is NOT the pagefile, it is a system the includes physical RAM and almost every file on your hard disk. The pagefile was designed to improve performance by temporarily storing rarely used data, thus leaving more RAM available for more important uses. Unless you have a very specific need and you understand what you are doing it is best to leave pagefile settings on default. Windows designers know more about the pagefile and memory management than you do. In all modern Windows systems every process is assigned a 4GB virtual address space. The lower 2GB is private to the process while the upper 2GB is used by the system. Note: this is a virtual address space and is completely independent of how much RAM is in the system. Also note, the lower 2GB is private, it is not shared with other processes. RAM is asigned to a process's addres space according to need and availability. A typical system might have 30 or processes running at one time. Since each one has a 2GB virtual address space you have a potential RAM usage of 30 x 2GB + 2GB system for a total of 62 GB! Still think you don't need virtual memory?

Not really. A single memory chip has the capacity to store a certain amount of data. Other mempry chips have larger or smaller capacity. Only when looking at a specific chip, then adding more chips increases the overall capacity (but typically also requires additional hardware). In the popular case of RAM modules used for desktop or laptop computers, the module's staorage capacity is not a function of the number of visible memory chips soldered onto the module.

No matter what the size of hard drive you have, you will eventually have to replace it. I built a computer in September 06. It had a 250 GB hard drive. I am probably the average computer user; I use mine for homework, a little bit of gaming, surfing the web, some DVD editing, and msn. My hard drive is about half full by now (June 07). I recently just added another 250 GB hard drive to use when my first one is full. You can add it on to your computer, so it might be fine to just start with a 250 or 320 GB hard drive and add another one in a year or so.

You can find the memory location in the service and maintenance guide for your laptop. Follow the link.

LOIP is an emerging technology whereby liquids can be delivered over the internet. The name "LOIP" is protected by trademark. Latest information is that the technology is still very much in the design stage and a consumer-product may be a year or two away, after several years of effort to date.

EEPROM (Electrically erasable programmable read-only memor)

The Compaq Armada supports up to 256 MB of SDRAM. If you have less than this amount (most models came with 64 MB to 128 MB), you can upgrade it.

SPD is short for Serial Presence Detect. It is a way for letting the computer know the specifications of its memory. That helps because the computer can automatically tune its memory access settings for the exact memory used based on the manufacturer's specifications. That is better than adjusting this manually and making errors which lead to frequent crashes.

An Intel atom processor will support at around 2 gb of ram

The chipset and the motherboard are the primary determination here. In fact there have been motherboards available which can take a couple different kinds of ram (so you can go with whatever is cheap) although not at the same time, but with the same CPU.

Pretty much, whatever your motherboard takes, that's what you've gotta use.

you need ddr2 240 pin

North Bridge

you need to see how much RAM your computer can hold, then what type for example DDR, DDR1 or DDR2, and what version for example pc3200 and then find some RAM and install it. be sure to wear an anti- static wrist strap to prevent any damage to the RAM.

The type of RAM your motherboard supports can only use that type and no other. If you have DDR2, you can not place a DDR or DDR3 module. If you mean can the game run the same on another system with different RAM, then quite possibly, but the speed of that memory may not be suitable for it.

1 byte = 8 bits.

Computers only know two things. On (1) and off (0). This is known as binary. Computers use an 8bit binary system (00000000).

The American Standrad Code for Information Interchange (ASCII) is an international code that notices that an 8bit character ASCI covers everything that you can type on a keyboard.

Therefore a 1byte letter is A to Z.

The time required by a processor to access data or to write data from and to memory chip is referred as access time.

The term DDR SDRAM refers to the phrase "double data rate synchronous dynamic random access memory". DDR SDRAM is simply a faster version of SDRAM in which data travels at a double rate. If your computer specs say that it uses DDR SDRAM it can take DDR SDRAM, but not SDRAM. DDR is 184 pins and has a notch in the bottom near the center and you will be unable to put DDR in an SDRAM mother board and also unable to put SDRAM in a DDR motherboard. Recently a new type of RAM has been introduced to market called DDR2. DDR2 is its own type and will not fit into a DDR motherboard. Hope this helps. Peace.

Both the above manufacturers, use SDRAM (old pc's), DDR (newish pc's), and DDR II (New pc's).

Occasionally, and very rare now, Intel used RDRAM (Rimms). Made by Rambus. These at the time, were the fastest ram you could purchase, with a FSB of 800Mhz. But literally cost the earth.

Hope this helps

No. In modern computers, programs are not stored on a ROM chip, but on the hard drive.
