What is common coupling?
Common coupling is said to occur when several modules have access to the same global data. External coupling occurs when two modules share an externally imposed data format, communication protocol, or device interface. This is basically related to the communication to external tools and devices.
Which type of coupling is best suited?
Next, for “Power Transmission” usage, “MJ” Jaw coupling is the most suitable. It can transmit high torque, accepting reasonable levels of misalignment. As it also has vibration absorption capability, Jaw type is widely used in many applications.
What are the common activities in design process?
The design process activities are the followings:
- Architectural design. The sub-systems of system and their relationships are identified based on the main functional requirements of software.
- Abstract specification.
- Interface design.
- Component design.
- Data structure design.
- Algorithm design.

What are the types of flexible coupling?
The following types of flexible couplings are the most common.
- Jaw Couplings. There are 3 types of jaw couplings: Straight Jaw, Curved Jaw and Jaw In-Shear .
- Gear Couplings. Gear couplings use gear teeth to transmit torque from one shaft to another.
- Grid Couplings.
- Fluid Couplings.
- Torsional Couplings.
What is the simplest type of coupling?
A gib head sunk keys hold the two shafts and sleeve together (this is the simplest type of the coupling) It is made from the cast iron and very simple to design and manufacture. It consists of a hollow pipe whose inner diameter is same as diameter of the shafts.
Which is the simplest type of coupling?
What are the common characteristics of design methods in software engineering?
Six characteristics of good software design—simplicity, coupling, cohesion, information hiding, performance, and security—are described. This is followed by a description of abstraction as the art of software design.
What are the fundamental activities that are common to all software processes?
The fundamental activities of a software process are:
- Specification.
- Design and Implementation.
- Validation.
- Evolution.
What is the most common measure for correctness?
Defects per KLOC
What is the most common measure for correctness? Defects per KLOC is the most common measure for correctness.
What is high cohesion and low coupling?
2. High cohesion, low coupling guideline. In essence, high cohesion means keeping parts of a code base that are related to each other in a single place. Low coupling, at the same time, is about separating unrelated parts of the code base as much as possible.
