If a process sleeps in algorithm iget when it finds the inode locked in the cache why must it start the loop?
When a process sleeps in the iget algorithm due to finding the inode locked in the cache, it must restart the loop to recheck the inode's status once it wakes up. This is necessary because the state of the inode may have changed while the process was sleeping, potentially allowing it to be unlocked or modified by another process. Restarting the loop ensures that the process verifies that it can safely access the inode without encountering any inconsistencies or race conditions. Thus, the loop allows for proper synchronization and guarantees the integrity of the inode access.

Why not make cache larger?
A cache is intended to speed things up. The larger the cache, the slower it performs. If it becomes slower to access the cache than the memory itself, it defeats the purpose of having a cache.
What is the name of the memory cache that is shared by cores in a multi-core processor?
L3 cache
The temporary file storage area of a Web browser is also called a?
Browser Cache
What is a Web Cache?
A Web cache is a temporary memory in your browser where temporary information about the web site you are visiting are stored. Information like login id, password, previous history of pages you visited etc would be stored in the cache...
Why do systems not use more or large cache memory if they are so useful?
cache is more expensive and it will increase the cost of the system terribly. processing of more than one cache will complicate the design of CPU and increase the burden on CPU.
What factors impact the performance of cache?
There are many factors that can affect cache performance, such as cache size, cache block size, association and replacement algorithm
Which cache mapping function does not require replacement algorithm?
direct mapping doesn't need replacement algorithm
What algorithm is considered reasonable for managing a buffer cache?
The Least Recently Used (LRU) algorithm is commonly considered reasonable for managing a buffer cache. LRU prioritizes keeping the most recently accessed items in the cache, as they are likely to be accessed again soon. This approach helps to optimize cache hit rates and minimize cache misses. Other alternatives like FIFO (First-In-First-Out) or LFU (Least Frequently Used) may also be used, but LRU generally provides better performance for many workloads.

Q No. 3: (a) How MMU is used to address the physical and logical cache arrangement Explain the difference between Least recently used and least frequently used replacement algorithm?
Q No. 3: (a) How MMU is used to address the physical and logical cache arrangement? Explain the difference between Least recently used and least frequently used replacement algorithm.
What happens if the process cannot access data from cache?
It means you have to fix your cache which is causing the data to not intake information
Does the process resides in cache memory or what?
No, but parts of its data and code are.
What is the process for implementing LRU replacement in a cache system?
To implement LRU (Least Recently Used) replacement in a cache system, the system keeps track of the order in which data items are accessed. When the cache is full and a new item needs to be added, the system removes the least recently used item from the cache to make space for the new item. This process helps optimize the cache by keeping frequently accessed items in memory.
Can you add moreL2 cache?
No, you cannot add more L2 cache to a processor after it has been manufactured. L2 cache is typically integrated directly into the CPU chip, and its size and configuration are determined during the manufacturing process. To increase L2 cache, you would need to upgrade to a different CPU model that offers more cache memory.
When was Cache Cache created?
Cache Cache was created in 1981.
What effect does cache memory on DMA?
1.DMA may lead to cache coherency problems. 2.May lead to bus error interrupt, which arent easy to process.
