What is the difference between memory address and memory addressability?
A memory address is a specific location in a computer's memory where data is stored. Memory addressability refers to the maximum amount of memory that a computer system can access and use. In other words, memory addressability is the range of memory addresses that a computer can access, while a memory address is a specific location within that range.
How many address lines are necessary to access 2k x 8 memory system using 256 x 8 memory chips?
Why do you want to waste 99.22% of the memory in these chips you supposedly will be spending good money on? Buy smaller sized memory chips more suitable for your purposes and design with them!
What is the purpose of the direct mapped cache tag in a computer system's memory management?
The purpose of the direct mapped cache tag in a computer system's memory management is to quickly determine if a requested memory address is stored in the cache memory. This helps improve the system's performance by reducing the time it takes to access data from the main memory.
How long can a memory be stored in a random access memory?
Indefinitely, as long as power is not removed from the system. Once power is removed, all address locations in RAM revert to their default state.
What is the formula to calculate the average memory access time in a computer system?
The formula to calculate the average memory access time in a computer system is: Average Memory Access Time Hit Time Miss Rate x Miss Penalty
How does memory access impact the overall performance of a computer system?
Memory access impacts the overall performance of a computer system by affecting how quickly data can be retrieved and processed. Faster memory access speeds up the execution of programs and tasks, leading to improved system performance. Slow memory access can cause delays and bottlenecks, slowing down the computer's operations.
Which memory is optional to start a computer system?
Random access memory (ram)
What are Base and Limit registers?
Base and Limit registers are hardware registers used in computer systems to define the memory range that a program can access. The Base register stores the starting memory address of a program, while the Limit register stores the size of the memory range that the program can access relative to the base address. This mechanism helps prevent programs from accessing memory outside of their allocated range, enhancing system security and stability.
What is sd ram memory?
Synchronous dynamic random access memory (in other words fast access memory that the computer uses for the operating system/kernal, and running programs)
What are the 2 types of memory called in a computer system?
RAM (Random Access Memory) and ROM (Read Only Memory).
What is the name of the file the operating system uses when it moves data from random access memory to virtual memory?
A swap file is the file that an operating system uses when it is moving data. A computer creates this file when it is moving data from random access memory to virtual memory.
What is the key task of a memory system?
The key task of a memory system is to memorize data in such a way as to have it readily available to the user. This is why computers have RAM (Random Access Memory).
