Q471.
What is common coupling?

a.

One module directly affects the working of another module

b.

Two modules have shared data

c.

Modules communicate through an external medium

d.

One module directs the execution of another module

Discuss
Answer: (b).Two modules have shared data Explanation:Common coupling occurs when two modules have shared data, such as the use of global variables or COMMON blocks in FORTRAN.
Q472.
What is external coupling?

a.

One module directly affects the working of another module

b.

Two modules have shared data

c.

Modules communicate through an external medium

d.

One module directs the execution of another module

Discuss
Answer: (c).Modules communicate through an external medium Explanation:External coupling occurs when modules communicate through an external medium, such as a file.
Q473.
What is control coupling?

a.

One module directly affects the working of another module

b.

Two modules have shared data

c.

Modules communicate through an external medium

d.

One module directs the execution of another module

Discuss
Answer: (d).One module directs the execution of another module Explanation:Control coupling occurs when one module directs the execution of another module by passing the necessary control information, usually through flags.
Q474.
What is stamp coupling?

a.

Complete data structures are passed from one module to another

b.

Two modules have shared data

c.

Modules communicate through an external medium

d.

One module directs the execution of another module

Discuss
Answer: (a).Complete data structures are passed from one module to another Explanation:Stamp coupling occurs when complete data structures are passed from one module to another, with the precise format of the data structures being a common property of the modules.
Q475.
What is data coupling?

a.

Complete data structures are passed from one module to another

b.

Two modules have shared data

c.

Modules communicate through an external medium, such as a file

d.

Only simple data is passed between modules

Discuss
Answer: (d).Only simple data is passed between modules Explanation:With data coupling, only simple data is passed between modules.
Q476.
What were the data types used in the programming languages in the 1970s?

a.

Scalars and records

b.

Records only

c.

Scalars only

d.

Scalars and arrays

Discuss
Answer: (a).Scalars and records Explanation:The programming languages in the 1970s had simple scalar data types such as real and integer, and they allowed arrays of scalar values. Records were used to store values of different types.
Q477.
What is considered data-coupled between modules in 1970s?

a.

Passing scalars or arrays

b.

Passing record data

c.

Passing control data through records

d.

Denying access to some modules

Discuss
Answer: (a).Passing scalars or arrays Explanation:Modules were considered data-coupled if they passed scalars or arrays.
Q478.
What is the relationship between A and B when A passes a scalar value to B and B returns a value which is used to control the further execution of A?

a.

A is control-coupled to B, B is data-coupled to A

b.

A is data-coupled to B, B is control-coupled to A

c.

A and B are both data-coupled

d.

A and B are both control-coupled

Discuss
Answer: (b).A is data-coupled to B, B is control-coupled to A Explanation:The coupling between modules need not be commutative, and when module A passes a scalar value to B and B returns a value which is used to control the further execution of A, then A is data-coupled to B, while B is control-coupled to A.
Q479.
What is the main benefit of having simple interfaces with weak coupling between modules and strong cohesion between a module's elements?

a.

Communication between programmers becomes more complex.

b.

Correctness proofs become harder to derive.

c.

It is more likely that changes will propagate to other modules, increasing maintenance costs.

d.

It increases the comprehensibility of modules.

Discuss
Answer: (d).It increases the comprehensibility of modules. Explanation:Simple module interfaces allow for an understanding of a module independent of the context in which it is used, which increases the comprehensibility of modules.
Q480.
What is the relationship between strong internal cohesion and intermodule coupling?

a.

Strong internal cohesion leads to high intermodule coupling.

b.

Strong internal cohesion leads to low intermodule coupling.

c.

Low internal cohesion leads to high intermodule coupling.

d.

Low internal cohesion leads to low intermodule coupling.

Discuss
Answer: (b).Strong internal cohesion leads to low intermodule coupling. Explanation:Coupling and cohesion are dual characteristics, so if the various modules exhibit strong internal cohesion, the intermodule coupling tends to be minimal.
