Understanding Processor Type Matching
This question requires matching different types of computer processors with their defining characteristics. Let's break down each processor type and its corresponding feature:
CISC Processors Explained
CISC stands for Complex Instruction Set Computer. Processors of this type are designed with a large number of instructions, including complex ones that can perform multiple low-level operations in a single command. This complexity aims to make the job of machine language programmers easier by reducing the number of instructions needed for a task.
Therefore, CISC processors match with characteristic III: "These possess so many processing features, making the job of machine language programmers easier".
RISC Processors Explained
RISC stands for Reduced Instruction Set Computer. In contrast to CISC, RISC processors feature a smaller, highly optimized set of instructions. These instructions are typically simpler and execute faster, often within a single clock cycle. The focus is on simplicity and speed.
Therefore, RISC processors match with characteristic IV: "Have a small instruction set".
EPIC Processors Explained
EPIC stands for Explicitly Parallel Instruction Computing. This architecture aims to improve performance by exposing parallelism explicitly. The compiler plays a crucial role in identifying and grouping independent instructions into bundles that can be executed in parallel. This differs from architectures where parallelism might be hidden or managed implicitly.
Therefore, EPIC processors match with characteristic II: "Use explicit parallelism".
Multicore Processors Explained
Multicore processors are processors that contain two or more independent central processing units (cores) on a single chip. In such systems, managing which task runs on which core is essential for efficient operation. This task assignment is primarily handled by the operating system, which schedules threads and processes across the available cores.
Therefore, Multicore processors match with characteristic I: "Operating system controls overall assignment of tasks".
Correct Processor Matching Summary
Based on the explanations, the correct matching between List - I (Processor Type) and List - II (Characteristics) is as follows:
List - I (Type of Processor) | List - II (Characteristics) |
A. CISC Processors | III. These possess so many processing features, making the job of machine language programmers easier |
B. RISC Processors | IV. Have a small instruction set |
C. EPIC Processors | II. Use explicit parallelism |
D. Multicore Processors | I. Operating system controls overall assignment of tasks |
Thus, the correct option is A-III, B-IV, C-II, D-I.
