What else can I help you with?
Which component on a computer stores permanent instructions which cannot be changed?
The ROM BIOS chip stores permanent instructions. ROM means read-only memory. BIOS means basic input/output system, meaning the very basic instructions needed to power up the computer. From there, the operating system loads.
What is the difference between primary and secondary memory?
P.M. memory includes RAM and ROM, which is temporary and permanent both. S.M. memory is just permanent memory which is used for the future. P.M. memory is used for the present work.
What Consists of electronic components that store instructions waiting to be executed by the processor data needed by those instructions and the results of processed data information?
Memory
What type of memory is long term where the specific instructions that are needed for the computer to operate are sorted?
The type of long-term memory that stores specific instructions for a computer to operate is called ROM (Read-Only Memory). ROM contains firmware, which is the permanent software programmed into the hardware that allows the computer to boot up and perform essential functions. Unlike RAM, ROM retains its data even when the computer is powered off, ensuring that critical instructions are always available.
Where does the following consists of electronic components that store instructions waiting to be executed and data needed by those ins?
The description refers to computer memory, specifically RAM (Random Access Memory). This type of memory temporarily stores instructions and data that the CPU (Central Processing Unit) needs while executing programs. Unlike permanent storage, RAM is volatile, meaning it loses its contents when the power is turned off.
How is a memory-resident part of an operating system different from a nonresident part of an system?
A memory-resident part of an operating system is continuously loaded into the computer's memory and ready for immediate use, enabling faster access and better system performance. On the other hand, a nonresident part is stored on the disk and is only loaded into memory when needed, causing delays in accessing the functionality.
What consists of electronic components that store instructions waiting to be executed by the processor data needed by those instructions and the results of processed data (information).?
Memory
The proper sequence of actions in a machine cycle is?
The proper sequence of actions in a machine cycle typically includes fetch, decode, execute, and writeback. During fetch, the CPU retrieves instructions from memory. In decode, the CPU translates the instructions into signals the computer can understand. The execute stage involves actually carrying out the instruction, and writeback stores the result back into memory if needed.
What is a unit that holds and gives information to the processor as needed?
A unit that holds and provides information to the processor as needed is known as the memory unit. This includes various types of memory, such as RAM (Random Access Memory), which temporarily stores data and instructions that the CPU needs for processing tasks. Additionally, cache memory serves as a high-speed storage area that allows for quicker access to frequently used data. Together, these memory components ensure efficient data retrieval and processing by the processor.
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 the interaction of ROM and RAM with CPU?
ROM (Read-Only Memory) and RAM (Random Access Memory) interact with the CPU by providing different types of data storage. ROM contains permanent instructions essential for booting the system, while RAM provides temporary storage for data and programs that the CPU actively uses during operation. The CPU retrieves instructions and data from RAM for processing, and it may access ROM for essential firmware instructions if needed. This collaboration ensures that the CPU can execute tasks efficiently by utilizing the fast access speed of RAM and the stable data provided by ROM.
What instructions remain on a storage medium until they are needed?
Instructions that remain on a storage medium until they are needed are typically referred to as "stored programs" or "software." These programs are saved in non-volatile memory, such as hard drives or solid-state drives, and they include the code and data necessary for a system to perform specific tasks. When required, the processor retrieves these instructions from storage, loads them into memory, and executes them. This concept underpins the operation of modern computers, allowing for efficient and flexible task management.
