Storage that retains its data after the power is turned off is referred to as?
non-volatile storage
Where is boot program stored in ROM and why?
The boot program is typically stored in a specific area of the Read-Only Memory (ROM) known as the BIOS (Basic Input/Output System) or firmware. It is placed in ROM because this memory type is non-volatile, meaning it retains its content even when the power is turned off. Storing the boot program in ROM ensures that the system can always access it to initialize hardware and load the operating system when powered on, providing a reliable start-up sequence.
Why is the permanent memory unit called so?
The permanent memory unit, often referred to as non-volatile memory, is called so because it retains stored information even when the power is turned off. This characteristic allows it to preserve data over time, making it essential for storing critical information like operating systems, applications, and user files. Unlike volatile memory, which loses its contents without power, permanent memory ensures that data remains intact and accessible when needed.
What is computer based financial information systems?
A computer based financial information system, is a system used to show the profits, taxes, wages and expenditures of a organization. It is usally on Microsoft Excel and can be turned into graphs and charts.
What is computer memory all about and its function in a computer?
Volatile memory is computer memory that requires power to maintain the stored information. Non-volatile random-access memory that retains its information when power is turned off. There is random access memory, cache memory, read only memory, virtual memory and flash memory.
What is direct installation?
In a new information system, on a directinstallation, the new system is installed and quickly made operational, and any overlapping systems are turned off. It is also know as immediate cutover.
What is a computer when it is turned on and the operating system is being loaded?
A computer is loading data when it is turned on and the operating system is being loaded.
What is volatility in computer?
It is the level of secondary storage that retains data when power is turned off. For example: Memory is volatile if it loses its data when the power is removed.
If you upgrade your microprocesser and memory in your desktop do you have to reinstall your operating system?
No, as long as you do not replace the hard drive. The hard drive is where all of the operating system files and other files are stored. Memory also called RAM is used only to make the computer faster by storing highly used files on them until the computer is turned off.
Is cache memory non volatile memory?
No, cache memory is a volatile type of memory, meaning the data stored in cache memory is lost when the power is turned off. Non-volatile memory, on the other hand, retains data even when the power is turned off.
What would be the result if a computer had only RAM and no secondary storage device?
Modern RAM (Random Access Memory) is a high speed semiconductor storage media that only retains information as long as power going through it. In any device that has no form of hard memory (ie. Solidstate or Disk drives), it will not keep information. As soon as the computer is turned off all the information on the RAM will be lost and you wont be able to get it back. There is some RAM that will keep information, however the amount kept is simply enough for your computer to know where the chips on the motherboard are and computer statistics. The result would be a computer with no operating system. With no operating system you could not load a web browser or do anything on your computer except play with the boring menus you see when you start up the computer.
Read only memory - keeps its memory even when the computer is turned off?
Yes, ROM (Read Only Memory) retains its contents even when the computer is turned off. RAM (Random Access Memory), on the other hand, loses its content the instant power is switched off.
