Computer Science Questions and Answers (Q&A)

During the Industrial revolution, the United States has contributed to the field of computer science by first inventing tools and equipment like the weaver and mechanical reapers. These inventions began the increase in technology at an early stage of history. Later, other inventors like Benjamin Franklin and Thomas Jefferson created mechanical devices that were involved in the field of computer science. Some contributions to science came by way of those who emigrated to the United States or presented information to the United States like Albert Einstein.

It is difficult to decide one person who contributed to the field of computer science, but Alexander Graham Bell has contributed the most to science and technology due to his invention of the telephone which allowed people to communicate over wires.

The correct answer to this question is B, 100.101. The binary system is numeric, and it writes numbers using only the digits 0 and 1. These two numbers are also known as a true and false state. In this system, a digit is as twice as much as a digit to the right of them.

Many people invented this system, but the credit goes to mathematician Gottfried Leibniz. He created the system in 1679. Since then, it has gone on to be used in computers and calculators. This type of question could be found on a math test, as well as SATs.

The answer to this is A. These four major parts of the computer are all working well together in order to create processes that will make people’s work faster. For example, the CPU is known to be the brain of the computer. Without this, the whole system will not work.

The memory is also important. Imagine having to do work and not having enough space to do your work. This can make things hard for you to do. The input and the output devices are also important because they can make the things that you are going to do with your computer easier to do and accomplish.

Many people often confuse Computer Science (CS) for Software Engineering (SE) as they use these terms interchangeably. However, Computer science is not the same as software engineering.

Computer Science is the study of how computers work, most notably from the theoretical and mathematical perspective. It focuses on understanding, designing, and developing programs and computers.

On the other hand, Software Engineering is the study of how software systems are built; it also focuses on project management, quality assurance, and software testing. It practically deals with building and maintaining software systems. It is more software-oriented than Computer Science.

Fortran is a general purpose imperative programming language that is especially suited to numeric computation and scientific computing. Fortran was originally developed by IBM. It was in the 1950s that fortran first came about and was first developed for scientific and engineering applications.

Fortran dominated its area even in the early days and has continued to do so even after more than fifty years of being around. Intensive areas within fortran include numerical weather prediction, finite element analysis, computational fluid dynamics, computational physics, and crystallography.

D (9 9876) this is because this can happen in two different ways. First by choosing from 9 digits 5 and then in how many ways one can arrange 0 if it must not start.

i.e P(9,5) 9

So the correct answer is D
