Iron Law of Performance in Computer Architecture
In computer architecture, the iron law of processor performance (or simply iron law of performance) describes the performance trade-off between complexity and the number of primitive instructions that processors use to perform calculations.
2. TPC-H is a decision support benchmark. It consists of a suite of business-oriented ad hoc queries and concurrent data modifications. The queries and the data populating the database have been chosen to have broad industry-wide relevance. This benchmark illustrates decision support systems that examine large volumes of data, execute queries with a high degree of complexity, and give answers to critical business questions.
ii) The TPC Benchmark (TPC-R) is a decision support benchmark similar to TPC-H, but which allows additional optimizations based on advance knowledge of the queries. It consists of a suite of business-oriented queries and concurrent data modifications.
iii) TPC Benchmark™ W (TPC-W) is a transactional web benchmark. The workload is performed in a controlled internet commerce environment that simulates the activities of a business oriented transactional web server. The workload exercises a breadth of system components associated with such environments,
AND Gate
An AND gate has a single output and two or more inputs.
When all of the inputs are 1, the output of this gate is 1.
The AND gate’s Boolean logic is Y=A.B if there are two inputs A and B.
