Computer Memory
The computer memory is a physical device used to store data or programs for use in a computer. Some types of computer memory include RAM (random access memory), ROM (read-only memory), and page cache.

Will increasing ram from 1000Mb to 2Gb make a big difference to speed?
No. Just a bit faster when you start OS Or during application loading or while playing games. Also 1000Mb is incorrect you must know that 1000Mb is not the same as 1000MB.
1000MB is 1GB. 2Gb is not the Same as 2GB=2048MB.
Although ECC memory costs more than non-ECC memory why would you chose to use it?
It is more reliable.
This would mean the operating frequency, in hertz or megahertz of the chips in the random access memory. Common values are between 100mHz and 800mHz. Newer computers generally have memory frequencies of 400mHz or more.
Where is interrupt vector table of 8086 Is it in the RAM or ROM?
Actually By Default this is present in BIOS(ROM) and at the boot time Operating System loads it to the RAM.
How do you determine less volatile and more volatile?
The higher the boiling point, the less volatile. And vice versa.
96,000 bits
However, in Kilobytes (KB), there would be 98304 bits.
Main memory:
Main memory is the computer's internal memory. It is an extension of the Central Processing Unit (CPU).
Its function is controlled by the Control Unit (CU) that sends READ or WRITE signal for the appropriate memory location. Main memory accepts data and instructions from the input unit, exchanges them with other parts of the CPU for processing. It stores those instructions and data, which are currently being used by the CPU or awaiting for immediate execution.
Semiconductor memories are the widely used forms of main storage. The capacity of a storage device is normally expressed in bytes, characters or bits. Computer's main memory is further divided into random access memory (RAM) and read only memory (ROM)

What is the maximum usable amount for 32-bit machine?
32-bit may refer to different things. Assuming the addressing is 32-bit, the machine can access 232 bytes, that is, 4 GB of RAM.
How many bits are needed to represent 18 symbols?
18 in binary is 10010
Since 18 can't be written in term of 2 to the power x, the number of bits needed is 5.
The answer is 5
This varies wildly by the kind of memory. There are a few common structures, however.
Physically, there is some sort of I/O interface (input/output). This is usually a series of pins, which connect the RAM module to the computer.
There is also the RAM cells themselves, usually small square black 'chips' containing so many MB or GB of data each.
There is usually some sort of SPD or logic chip which identifies the RAM and it's default operating parameters, but is not always the case.
And there is always a memory controller, although this may not be on the RAM itself but is usually on the motherboard, or in the case of AMD, built into the CPU.
Logically, there are 'rows', 'columns', and 'banks'.
Rows and columns work just like a spreadsheet, and are used to access individual sectors inside the memory chips. This applies to each chip or bank on the memory.
Are external hard drives reliable?
Yes they are. They're also a VERY good way of backing up all the information on your computer in case it gets stolen !
Most external hard-drives simply connect to a spare USB port - making them quick and easy to use.
I know this sounds like a put off answer but you cannot tell the number of sticks you need inside a computer just based on using DIMMS..DIMM is the brand type of the memory, it means Dual Inline Memory Chip, which means that RAM is on both sides of the stick. It does not have anyting to do with how many sticks of RAM you use. The only way to check is to either open up your computer and see how many RAM slots you have or check the manufactorers website. Sorry but that's the way it works. .
What is being used when your computer starts to use the hard drive for additional memory?
It's called virtual memory.
What do you call Using space on hard drive as if it was ram?
you're using virtual memory/a paging file
