Computer Science
Computer Science is the systematic study of algorithmic processes that describe and transform information. It includes the theoretical foundations of information and computation and the practical techniques of applying those foundations to computer systems. Among the many subfields of Computer Science are computer graphics, computer programming, computational complexity theory, and human-computer interaction. Questions about Computer Science, terms such as algorithms and proofs, and methodologies are encouraged in this category.

What does the cardinality ratio specify?
The cardinality ratio specifies the number of relationship instances that an entity can participate in.
What is nesting in computer science?
Nesting is the process of organizing information in layers. For an example, a loop in a program can contain another loop which can contain yet another loop. This is called nested loops.
What is meant by an organic approach?
Organic approach, in contrast to the mechanistic approach, in the project management area is a way to manage/organize/and delegate the work in a more decentralized fashion. Every individuals in the project are given a clear set of performance targets that they are motivated to achieve. Those performance targets define the results that are expected but then people figure out for themselves how to deliver the results. The theory behind it is that flexibility allows people to work at their best if they can think for themselves and control their own actions efficiently adapting real-time situation changes.
Why you use many processors in a mainframe computers?
Mainframe computers are used for bigger and complex environment than mini computer, so many processors are used to increase the efficiency of data processing.
It also provides another benifit i.e. a mainframe computer is able to continue to be in service with remaining processors in case one processor is failed.
What is the sum of the values stored in cells b4 b5 b6 and b7?
Use following function in any other cell to calculate sum: =sum(b4:b7)
How many megabytes makes up 1GB?
Depending on your numbering scheme, either 1024MB or 1000MB makes up 1GB.
Bytes are groups of binary digits, 1's and 0's, that consists of 8 bits. There is nothing really weird about them, although some computer programmers do become frustrated with programming them.
Git is part of software development, to make certain database type software run faster and work better. It is called a distributed version control and source code management system and supports merging in software.
What are signals that inform the Operating System that something has happened?
Messages or values in registers. Messages are passed between programs and the operating system to tell something else what to do. For example, when you click on a program, the computer does not directly run the program's code. The operating system receives a message telling it to run the specified program and does so. It makes note of this in internal registers, which keep track of what program is executing and what line of code is being executed.
What is DIM statement in BASIC?
Declares and allocates storage space for one or more variables.
i.e. Dim A1() As Integer = {0, 1, 2, 3}
What are the three buffering approaches used in computers?
Basically, each different buffering method is suited for different things. Some support First in First Out Method and others Last in First Out. Think of a youtube video, you want to watch it frombeginningto end right? So what if your buffer was going in the wrong way? It would start loading the end of the video first. Thats a big problem. The same goes for other video players. In downloading games or other types of downloads, download order isn't vital as you can't play without all the files. So essentially its about load order
How do you declare variables and constants.explain with example?
Depends on the programming language you are using. I will give two simple examples.
In Command Prompt and when creating a batch file, you declare a variable by entering the "set" command. You can use different switches to change the type of variable you are declaring.
/p makes the variable able to accept user input.
/a makes the variable a numerical expression.
In Python, you declare a variable just by stating the name of the variable and its value.
x = value.
Security goals refer to the fundamental objectives that guide the development and implementation of security measures within an organization or system. These typically include confidentiality (ensuring that sensitive information is accessible only to authorized individuals), integrity (maintaining the accuracy and reliability of data), and availability (ensuring that information and resources are accessible when needed). Other important goals may encompass accountability, non-repudiation, and resilience against threats. Together, these goals help to protect assets and mitigate risks in various environments.
What is the full form of PSIL?

Pacific Satellite International Limited (Hong Kong)
Pacific Simulators International Limited (flight training)

What is the most appropriate software for calculating in computer?
The choice of the most appropriate software for calculating entirely depends on the type of calculations required.
Popular spreadsheet programs such as Microsoft Office Excel (free alternatives exist with Open Office or Libre Office, and others) are great for visualizing simple data sets and performing simple numeric and statistical calculations. The typical use-case for spreadsheet programs are "what-if" cases, where one can examine the result of changing one or more parameters into a calculation.
More powerful mathematical tools provide higher level mathematics, statistics and data visualization tools. These higher level tools also typically provide support for complex numbers, symbolic arithmetic and calculus. Representatives of this group of mathematical software include Mathlab and Mathematica.
On the other end of the scale, the standard Windows Calculator (or similar tools on other operating systems) provide the functionality of a regular calculator, typically with added features such as history, multi-step undo, or support for different numeric bases (e.g. binary, decimal, hexadecimal).
Among software development tools and programming languages, the Fortran language was favored among scientists and mathematicians for many years on account of its built-in support for complex numbers and complex arithmetic. Today, however, most modern languages support toolkits for complex numbers, high precision arithmetic and many other specialist numeric applications.
Why calculus is important for computer scientist?
An understanding of the math behind the problem will help you solve the problem. High-level Computer Science is about modeling natural sciences which is where you will need to understand the basics of calculus.
Why data structuring is important in computer science?
Data structures basically deals with the question: how data can be organized so that it can be processed efficiently? That is, it discusses different data organizations suitable for different situations along with their associated algorithms. Data Structures. It is considered to be one of the most important courses in computer science as it equips the students with fundamental building blocks for the development and design of complex systems such as operating systems, compilers, and database management systems.
CUI means Command User Interface.
In such a software, we can use only commands to run, edit or terminate a program.
if a language is recognized by NFA then it can also be recognized by DFA so we can simply say that
NFA=DFA
