What is the main working memory of a computer when the power is switch off the data is this memory is lost?
The main working memory of a computer is its Random Access Memory (RAM). When the power is switched off, all data stored in RAM is lost because it is volatile memory, meaning it requires a constant power supply to maintain the stored information. In contrast, non-volatile memory types, like hard drives or SSDs, retain data even when powered down.
How can the processor find data items stored in main memory?
The software would tell it where to find the items.
Where The information stored in RAM is erased when the computer is turned off?
Main computer memory is called volatile memory. It holds data only as long as it is provided power. When you turn off the computer, you remove power from the memory chips and they loose the ability to hold data. If you want to keep your information, ensure you save it to the computer hard drive before you switch off the computer.
Distinguish between in primary and secondary memory?
Memory can be categorized in different ways by technology or properties: primary access by the CPU or secondary (indirect) access by the CPU. This distinction is primarily based on the speed of access to the memory. volatile or non-volatile is a distinction based on technology (magnetic vs. electrical, etc.). Volatile memory requires power to maintain its stored information. Read-only memory, or read-write is a distinction based on properties of the memory. Read only memory, or "ROM", is not modifiable.
What can be stored in the main memory of a computer system?
Computer memory
What is volatile and why are using in java?
volatile variable is mainly used in multithreading environment. so let me explain it from that context.In a multithreading environment,for a variable which is not marked as volatile will be stored in local cache memory for each thread. Meaning each thread will have a local copy of the variable and they dont know about what value this variable is having in another thread. If a variable is marked volatile, then the updations to this variable will happen in the main memory and not in local cache
Is BIOS volatile or non volatile?
BIOS is a program (stored in ROM), not a memory.However the BIOS uses a battery backed up RAM to store a variety of settings and parameters. This BIOS RAM is itself volatile (it can only store data when powered), however the battery backup provides power to this RAM when the main power of the computer is off (making it act as if it were nonvolatile). When this battery dies the BIOS RAM will lose its data and (after the battery is replaced) the machine may have to be reconfigured from scratch before the machine will startup correctly.
What are the categories of main memory?
Main memory, or primary memory, is primarily categorized into two types: RAM (Random Access Memory) and ROM (Read-Only Memory). RAM is volatile and used for temporary data storage while a computer is running, allowing for quick read and write access. ROM, on the other hand, is non-volatile and stores firmware or software that is not intended to be modified frequently. Additionally, RAM can be further divided into DRAM (Dynamic RAM) and SRAM (Static RAM), each with different performance characteristics.
Which of the following terms is the most closely related to main memory?
non volatile ROM
Global variables are stored in?
Main memory (RAM).
Which system software resides in main memory?
LOADERS
Where is the operating system located in the computer?
The operator system is software- a program that controls the computer. It is usually stored on the hard drive when the computer is not running and is read into a special portion of main memory when the computer is booted up. (There is a boot strap program stored on a chip that loads the O. S. into memory. ) Some of the routines needed by the operating system are not kept in the main memory but are read in only as they are needed.
