Volatile memory is memory that requires electric current to retain data. When the power is turned off, all data is erased. ... Computers and other electronic devices use RAM for high-speed data access. The read/write speed of RAM is typically several times faster than a mass storage device, such as a hard disk or SSD.
Which type of memory is erased when the computer is turned off quizlet?
RAM is held on a computer chip. It is volatile memory because the contents disappear when the power is turned off. It’s memory can be read from and written to. You just studied 26 terms!
Which type of memory is erased when the computer is turned off?
RAM is volatile memory , which means that the information temporarily stored in the module is erased when you restart or shut down your computer. Because the information is stored electrically on transistors, when there is no electric current, the data disappears.
What is lost when the computer is turned off?
Your computer’s RAM loses its data when the power goes off. Your computer has different kinds of memory, some of which saves its data when you turn the power off, some which does not. Computer scientists call the former kind of memory non-volatile and the latter volatile.
Is ROM erased when the computer is turned off?
ROM. ... The data in ROM is nonvolatile and isn’t lost when the computer power is turned off. As a result, read-only memory is used for permanent data storage. Random Access Memory, on the other hand, can only hold data temporarily.
When the computer is turned off this memory does not lose data?
known as VOLATILE memory . ROM stands for READ ONLY MEMORY and is non-volatile memory. When the computer is shut down the data remains stored. If a computer doesn’t have enough RAM is can use a portion of its HARD DRIVE as memory, this is known as VIRTUAL memory.
What is RAM in memory?
Random access memory (RAM) is a computer’s short-term memory, which it uses to handle all active tasks and apps.
What controls the computer memory?
The Central Processing Unit (CPU) The computer does its primary work in a part of the machine we cannot see, a control center that converts data input to information output. ... The CPU interacts closely with primary storage, or main memory, referring to it for both instructions and data.
What software controls a computer’s basic functions?
System software controls a computer’s internal functioning, chiefly through an operating system , and also controls such peripherals as monitors, printers, and storage devices.
What are two types of memory in computer?
There are basically two kinds of internal memory: ROM and RAM . ROM stands for read-only memory. It is non-volatile, which means it can retain data even without power.
Where is the main memory of a computer?
Main memory is the primary, internal workspace in the computer , commonly known as RAM (random access memory). Specifications such as 4GB, 8GB, 12GB and 16GB almost always refer to the capacity of RAM. In contrast, disk or solid state storage capacities in a computer are typically 128GB or 256GB and higher.
Is a permanent memory?
The permanent memory of a computer is known as ROM(Read-only memory) . In computers and other electronic devices, read-only memory (ROM) is a form of non-volatile memory. After the memory unit is manufactured, data contained in ROM cannot be electronically changed.
Which memory device loses data on power failure?
Volatile memory , in contrast to non-volatile memory, is computer memory that requires power to maintain the stored information; it retains its contents while powered on but when the power is interrupted, the stored data is quickly lost. Volatile memory has several uses including as primary storage.
What happens to anything in RAM when you power off your computer?
RAM is often referred to as volatile memory, because anything contained in RAM is considered lost when a computer is switched off . Indeed, all data is lost from RAM when the power supply is disconnected; so it is volatile in this context.
What type of RAM loses its data rapidly?
| Question Answer | when the power is turned off, both SRAM and DRAM lose all their data, and are therefore called volatile memory | ________ RAM loses its data rapidly, and the memory controller must refresh it several thousand times a second Dynamic |

Which memory is used for starting up a computer ?:?
The CPU starts and fetches instructions into RAM from the BIOS, which is stored in the ROM . The BIOS starts the monitor and keyboard, and does some basic checks to make sure the computer is working properly.
