What is locality of reference?
Locality of reference is a principle in computer science that states that data or instructions that have been recently accessed are likely to be accessed again in the near future. This principle is the basis for various optimization techniques in computing systems, such as caching and prefetching, to improve performance by exploiting this predictable access pattern of data.
The provide easy access to frequently used commands?
The _____ provides easy access to frequently used commands
Lists the most recently used commands?
Press the upper cursor key at the terminal prompt to reveal the recently used commands. Or type history for a longer list.
What is the significance of the LRU replacement policy in cache management strategies?
The Least Recently Used (LRU) replacement policy is significant in cache management strategies because it helps to optimize the use of cache memory by replacing the least recently accessed data when the cache is full. This ensures that the most frequently accessed data remains in the cache, improving overall system performance by reducing the number of cache misses.
How old is personal information that is found via searching on a computer?
The age of personal information found on a computer depends on when it was last updated or accessed. The information could be recent if it was accessed recently, or it could be older if it has not been updated for a long time. It is important to consider the last modification date or time stamp to determine the age of the personal information.
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.
What is a feature that Internet browsers provide to improve performance when accessing recently visited websites?
caching recently accessed pages
How does a 2-way set associative cache implement the Least Recently Used (LRU) replacement policy?
In a 2-way set associative cache, the LRU replacement policy is implemented by keeping track of the order in which the cache lines are accessed. When a cache line needs to be replaced, the line that was accessed least recently within the set is chosen for replacement. This helps optimize cache performance by removing the least frequently used data.
What is the data found in the cache is called?
The data found in the cache is called cache data. It typically consists of recently accessed or frequently used instructions or data that are stored in a smaller and faster memory area for quicker access by the processor.
What is recent directory?
A recent directory is the folder (or drive) that was accessed/used most recently.
Which command syntax lets you view your most recently entered commands?
show history
The top left section of the Start menu contains what type of items?
Recently accessed programs
