MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -SISD (Single Instruction, Single Data) refers to the traditional von Neumann architecture where a single sequential processing element (PE) operates on a single stream of data. SIMD (Single Instruction, Multiple Data) performs the same operation on multiple data items simultaneously.

Detailed explanation-2: -SISD is a uniprocessor machine capable of executing a single instruction, which operates on single data stream. Von neumann computer architecture is SISD.

Detailed explanation-3: -The Von Neumann architecture consists of a single, shared memory for programs and data, a single bus for memory access, an arithmetic unit, and a program control unit. The Von Neumann processor operates fetching and execution cycles seriously.

Detailed explanation-4: -In computing, single instruction stream, single data stream (SISD) is a computer architecture in which a single uni-core processor executes a single instruction stream, to operate on data stored in a single memory. This corresponds to the von Neumann architecture.

Detailed explanation-5: -This taxonomy defines four different styles as follows − Single instruction stream, single data stream (SISD) Single instruction stream, multiple data stream (SIMD) Multiple instruction stream, single data stream (MISD) Multiple instruction stream, multiple data stream (MIMD).
