What did you learn from the links Sra posted yesterday when you asked this identical question??
i am not sure L1 OR L2,it could be L1
this is litle bit hard for me because is second language
a. is correct.
L1,L2... stand for Level 1 cache, Level 2 cache, etc.
A cache memory is a high speed memory that stores information that is used over and over again. This way, the computer's central processing unit (CPU) does not have to wait for the information to be loaded from slower memory, or even the disk.
Level 1 cache is built in, and becomes part of the CPU chip, so it is almost always present in a personal computer. It is usually very fast static memory that does not require frequent refreshing (hence less time lost).
Level 2 cache can be present as a separate memory chip, or at times also built into the processor. This way, most personal computers almost always contain L2 memory.
Level 3 is slower, and usually has a larger capacity.
Level 4 memory is even larger and slower. However, a the benefits of a huge cache is doubtful. Therefore the presence of L4 memory in personal computers is not guaranteed.
L1
Yes, the correct answer is a) L1.
L1 (Level 1) cache memory is the type of high-speed memory that is common to almost all personal computers. It is located on the processor chip itself and is the closest and fastest memory to the CPU (Central Processing Unit). L1 cache is used to store frequently accessed instructions and data to speed up the CPU's performance.
To arrive at this answer, you can consider the following information:
- The hierarchy of cache memory in a computer system usually consists of multiple levels, such as L1, L2, L3, and sometimes L4.
- L1 cache is the first and smallest level of cache memory, typically around a few kilobytes in size.
- L1 cache is directly integrated into the CPU and provides the fastest access time compared to higher-level caches.
- Personal computers generally have L1 cache memory, as it is essential for optimizing the CPU's performance.
Therefore, based on this information, the correct answer is L1.
