Reading comprehension

Read the following passage and answer the questions that follow:

Some decades back, when computers were just born and were a completely new thing to people, very few could operate them and software was not given much emphasis. At that time hardware was the most important part that decided the cost of implementation and success rate of the system developed. Very few people were known to programming. Computer programming was very much considered to be an art gifted to few rather than skill of logical thinking. This approach was full of risk and even in most of the cases, the system that was undertaken for development, never met the completion. Soon after that, some emphasis was given on software development. This started a new era of software development. Slowly, people started giving more importance to software development.



People, who wrote software, hardly followed any methodology, approach or discipline that would lead to a successful implementation of a bug-free and fully functional system. There hardly existed any specific documentation, system design approach and related documents etc. These things were confined to only those who developed hardware systems. Software development plans and designs were confined to only concepts in the mind.

Even after a number of people jumped in to this field, there was a lack of proper developmental strategies, documentations and maintenance plans. Therefore the software system that was developed was costlier than before, it took more time to develop the entire system (sometimes, it was next to impossible to predict the completion date of the system that was under development). The lines of codes were increased to a very large number increasing the complexity of the project/software. As the complexity of the software increased it also increased the number of bugs/problems in the system. Most of the times the system that was developed, was unusable by the customer because of problems such as late delivery (generally very late) and also because of the number of bugs. There were no plans to deal with situations where systems were to be maintained. This led to a situation called ‘Software Crisis’. Most of the software projects, which were just concepts in the mind, had no standard methodologies or practices and experienced failure, causing loss of millions of dollars.

‘Software Crisis’ was a situation, which made people think seriously about the software development processes, and practices that could be followed to ensure a successful, cost-effective system implementation, which could be delivered on time and used by the customer. People were compelled to think about new ideas of systematic development of software systems. This approach gave birth to the most crucial part of the software development process, this part constituted the most modern and advanced thinking and even the basics of any project management, it needed the software development process be given an engineering perspective thought. This approach is called as ‘Software Engineering’.

Standard definition of ‘Software Engineering’ is ‘the application of systematic, disciplined, quantifiable, approach to the development, operation and maintenance of software i.e. the application of engineering to software. ’

Software Engineering takes an all-round approach to find out the customer’s needs and it even asks customers about their opinions proceeding towards development of a desired product. Various methodologies/practices such as ‘Waterfall Model’, ‘Spiral Model’ etc. are developed under Software Engineering which provides guidelines to follow during software development ensuring on time completion of the project. These approaches help in dividing the software development process into small tasks/phases such as requirement gathering and analysis, system design phase, coding phase etc. that makes it very much easy to manage the project. These methods/approaches also help in understanding the problems faced (which occur during the system development process and even after the deployment of the system at customer’s site) and strategies to be followed to take care of all the problems and providing a strong support for the system developed (for example: the problems with one phase are resolved in the next phase, and after deployment of the product, problems related to the system such as queries and bugs that were not yet detected etc. which is called support and maintenance of the system. All these strategies are decided while following the various methodologies).

48. When computers were just invented software programming was-

a.    not invented
b.    not given any importance
c.    not known
d.    very few people knew it

49. In those early years what decided the implementation cost and success rate of a system?

a.    the computer peripherals
b.    the shape and size of the computer
c.    the punch cards used by the computers
d.    the hardware cost of the system

50. Which one of the following was not a problem even after many people started software programming?

a.    cost of production was very high
b.    the programming had lots of faults
c.    the programming had lots of bugs
d.    software took very little time to produce

51. What were the reasons for causing loss to millions of dollars?
a.    software projects were just concepts in the mind
b.    they had no standard methodologies
c.    they were totally without any direction
d.    software projects were just concepts and had no standard methodologies

52. What is ‘Software Crisis’?

a. a serious crisis in the computer industry leading to a breakdown of systems
b. serious deliberation about producing a user friendly software
c. a groundbreaking breakthrough in software development
d. creating a software to please the customer

53. The new software development process was given an engineering perspective thought, and this was called-

a.    business development
b.    hardware development
c.    software engineering
d.    process engineering

54. Whose help does a software engineer seek to develop a good product for the customer?

a.    customer
b.    colleagues
c.    internet
d.    team leader

55. What are the different models mentioned in the passage?

a.    linear model
b.    spiral model
c.    waterfall model
d.    spiral and waterfall models
