Is to read things on the computer or to hold a paticular document
Without RAM, a CPU can not execute any code at all, or access any data. The Operating System must be stored in RAM or the CPU can not access the code necessary to run the Operating System. Also, files that the user is working on must be stored in RAM or they are not accessible.
RAM is the exact equivalent in a human being to short-term memory. In working with anything, you are relying constantly on your short-term memory. The info your are "keeping close and handy". This is what RAM does in the computer. Imagine writing a letter, and at the end of each sentence, you have no recall of what the previous sentence - or the one before that - was. Short term memory keeps you on track. On the computer, that is what RAM does. You don't have to start over, or find it again - it's right there.
All software, when run, resides in the random access memory (RAM) of a computer. Memory requirements are defined after considering demands of the application, operating system, supporting software and files, and other running processes. Optimal performance of other unrelated software running on a multi-tasking computer system is also considered when defining this requirement.

What are the four basic modules of operating system might be required on a computer system where there is multiprogamming?
The system consists of CPU, Main Memory, I/O Module, and System Bus.
What is virtual memory and how the system controls the situation in the absence of it?
What is virtual memory and how the system controls the situation in the absence of it?
Some early computers protected the operating system by placing it in a memory partition that could not be modified by either the user job or the operating system itself. Describe two difficulties?
The data required by the operating system (passwords, access controls, accounting information, and so on) would have to be stored in or passed through unprotected memory and thus be accessible to unauthorized users. Akmal Waheed waheed007@gmail.com
What are four resources required for process execution?
various CPU registers where process need to be stored for execution for running state.process priority and other scheduling information which is required to schedule the information of page table.memory limitssegment table depending on the memory used by the operating system
What is the use of virtual memory?
Virtual memory is used to increase the size of working memory in the system main memory by using the locations in secondary storage such as harddisk.
What is the price of the memory module required to configure your system for maximum memory?
phisical
What is the minimum system memory required to run Aero in Windows Vista?

What are the four basic modules of operating system might be required on a computer system where there is multiprogamming?
The system consists of CPU, Main Memory, I/O Module, and System Bus.
What is memory word size required in an 8085 system?
In an 8085 system, the memory word size required is 8 bits. This means that each memory location can store 8 bits or one byte of data. The 8085 processor accesses memory locations using these 8-bit memory addresses to read or write data during program execution. The memory word size of 8 bits allows the 8085 system to handle data in small, manageable chunks efficiently.
What is system heap?
In programming, it refers to a common pool of memory that is available to the program. The management of the heap is either done by the applications themselves, allocating and deallocating memory as required, or by the operating system or other system program. Source: Answers.com
Why is is auxiliary memory required?
Auxillary memory is required so that set of instruction given first stored in temorary memory which can be edited & then can be stored
What is another name for working memory?
Another name for working memory is short-term memory. It refers to the system in the brain responsible for temporarily storing and managing information required to carry out cognitive tasks such as learning, reasoning, and comprehension.
What is the difference between dedicated and shared graphics?
Some graphics cards have memory on board the card itself. Others rely on the memory chips on the system board for memory , thus sharing memory. Suppose a PC has a specification of 256MB of memory and 64MB shared graphics. The memory available for your operating system and applications will be 192MB. If a PC had the same specifications but the 64MB were dedicated, the 64MB required to run the card would use this memory, leaving the full 256MB for your operating system and applications. In short, shared = compromise, dedicated = better.
When does page fault occur?
A page fault occurs when a program accesses a memory page that is not currently in physical memory (RAM). This triggers the operating system to fetch the required page from secondary memory (disk) into RAM, allowing the program to continue execution.
How much storage does a memory card have?
I think I am answering this correctly. Memory is also called RAM or DDRAM, SDRAM etc. 512MB of memory is 512MB of memory. If you check the back of your software cases you will notice that it gives you the system minimum and recommended for memory required. Example windows 7 recommends 1GB of system memory minimum to install and run.
