MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Harvard Architecture has separate memory for data and instructions. In that way, both instruction and data can be fetched at the same time, thus making it comfortable for the users. In Harvard Architecture, Instructions are used in Read-only memory and, Data are used in Read-Write Memory.

Detailed explanation-2: -RISC uses the Harvard memory model means it is Harvard architecture. RISC ( Reduced Instruction Set Computer ):-It is a microprocessor that is designed to perform a smaller number of types of computer instructions so that it can operate at a higher speed.

Detailed explanation-3: -Harvard architecture has a higher performance than Von Neumann due to the presence of the two separate memory spaces (data memory and instructions memory). This makes Harvard architecture execute data and instructions faster as compared to Von Neumann architecture.

Detailed explanation-4: -Explanation: Harvard Architecture provides separated buses for data and program memory to fetch program and data simultaneously. By doing this access time is reduced and hence performance is increased.

Detailed explanation-5: -Harvard architecture is used primary for small embedded computers and signal processing (DSP). Von Neumann is better for desktop computers, laptops, workstations and high performance computers. Some computers may use advantages from both architectures.
