Discuss the data replication on the distributed database system? The data replica is a term that refers to the data replication means the copy of data into the servers distributed to access the copy of data. The data replication in a distributed database system is a term that provides the benefits for the user to easily access the data from the nearby server provided for the client user from the website. The data can be easily accessible from the server and provide the fast speed with reduces the latency of the data transfer to the client server such as:- if the user access the data from their smartphone device then the data will be fast to load because the nearby server provide the data replicated or copied of data to the user. Data replication in a distributed database system involves creating and maintaining multiple copies of data across different nodes or locations to enhance availability, reliability, and performance. It ensures that users can access data even if a node fails, re...
What is cache memory? How is it different from primary memory? Definition of cache memory Cache memory is a high speed memory built in the processor and used between the main memory and the processor. 1. Cache is memory is placed between the CPU and the main memory. fig: describe the cache works between CPU & main memory. 2. Cache memory is faster than the main memory . fig: The Cache memory is faster than the main memory according to working performance. 3. Its access time is less than the main memory . fig: Cache performance of access time lower than main memory. 4. According to measurement the cache memory access time is 10 to 30 nano second (ns) and the main memory access time is 80 (ns) nano second . table of access time of both memory. 5. The Cache memory stores instructions and data that are immediately executed. fig describes that cache memory stores Instructions & Data but sometimes it don't stores data. 6....
