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.

Why did ram was suspicious on Sita several times?
Ram was Suspicious on his wife Sita when he brought sita from Srilanka . He not only Suspicious on her once but several times. He was Suspicious & when a Dhobi told him that when sita was in Srilanka she has gone days ( Stage of Pregnancy ).
Hearing this Ram became Annoyed & he send sita to a remote village where there were no facilities like living life in luxury. There she gave birth to Luv & Kush . Even
Walmiki used to stay there but he wrote false ramayan. The true ramayan ramayan is written by Periyar Ramaswamy Naikar. Ram never gave let sita has his queen.
What does CL or RL rating refer to in terms of RAM?
CL is the same as CAS Latency and RL is the same as RAS Latency. They both pertain to the number of clock cycles it takes to write of read a colum or row of data off a memory module.

Why register to register instruction is faster?
Register to register addressing mode is faster because you don't have to do an extra memory access cycle or more.
Register to register addressing mode is faster because:
- Registers are part of and are directly accessibility by the CPU assembly.
- They electronics that make up a register use more expensive but faster circuitry.
- Since it does not require memory access, the steps and time involved in memory address decoding and memory access are skipped.
It is not possible. A Byte is 8 bits, the largest possible 8 bit number is '11111111' which is only 255 (in normal decimal numbers).
How can you increase your memory if you are always stressed-out?
The power of silence will help you. Just remove 1 hour in a day and remain silent throughout that hour. Talk with yourself. Introspect. To connect with the outer world, you first need to connect yourself. Your solution here is not increasing your memory, but actually decreasing your stress. And silence will help you decrease the stress. Once your mind isn't stressed, your memory will automatically become more clear and focused towards whatever you do.

How much memory is lost after formatting a disc?
When a disk is formatted or reformatted, everything previously on the disk is lost.
'Memory' in computer terms does not usually refer to the data that is on a separate disk. In the computer system there are various forms of 'memory'...
- At the highest level there is the data stored in the internal registries.
- Next there is a processor cache of memory.
- Next there is 'Random Access Memory' (RAM). This is in the form of a special slot-in unit in the PC.
- Then there is the hard-drive. This also serves as memory. It holds the programmes and related input and output data. The hard drive has its own 'disks'. If you format or re-format your hard drive you will lose everything! Don't do it! (Formatting a hard-drive disk should only be done by someone who knows what they are doing!)
Data can also be stored on extra drives, internal or external, and can take various forms, e.g. other hard-disks, 'flash drives', USB memory sticks, etc. These devices are used to store of various types of data such as pictures, music, text files, spreadsheets etc. Data stored in this way is a form of 'memory'.
Formatting or re-formatting one of these storage devices will destroy all the data that was previously on it. 'Formatting' wipes a disk clean of data, and divides its storage capacity into many sectors to enable future data to be readily stored and accessed in an organised way.
A buffer is an area of high speed memory that sits between the processor and the primary memory?
You should ask the question without the word "buffer" in the sentence. The correct statement would be;
A Cache is an area of high speed memory that sits between the processor and the primary memory.
What are subdivision of computer main memory?
Input Storage Area
Working Storage Area
Output Storage Area
Program Storage Area
Is there any difference between RAM and ROM how?
Ram=RAMDOM Access Memory, example your memory ram stick/s when you turn off or reset your PC everything stored there will be lose because it only keep temporal information while is on.
Rom= READ Only Memory, example your Hard Drive, here is where you store all your info for a later use if you want and once stored the PC can be shut down and you still will have everything if you saved it when you turn back on your PC.
What is the difference between a disk and a tape?
Disk allows for writing and reading any part of the disk at any time. This allows us to be playing games, surfing the web, and listening to music all at the same time. If we were to do this on tape, we would be able to only access the things in order they were on the tape, or we would have to wait while it scans the tape for our music, looking for empty space so we could download that latest patch.
Tape is a great way to backup your data because it's pretty cheep and easily stored and moved, but its only real use is bulk reading and writing (batch processing) of large amounts of data and other similar processes.
Disks are prone to mechanical failure, but allow for reading and writing files much easier and quicker but for a cost.
Tape is still widely used in a cooperate setting for off-site backups and for internal backups as accessing time while looking for a file to recover are not a concern where getting the file for your presentation in 5 minutes needs to be instant.
