Computer Science & Software Engineering


What is Engineering?

To make something to be happen in a most efficient and feasible way.

Computer Science?

is a study of  scientific and practical approach to computation and its applications.

Computation: computation is any type of calculation that follows well-defined model understood and expressed as , for example , algorithm, or a protocol.

The branch deals with design , implementation, management of information system of both software and hardware.

Areas of Computer Science:
i. Theoretical computer science
ii. Theory of computation
iii. Information and coding Theory
iv. Algorithms and Data structures
v. Programming Language Theory
vi. Formal Methods
vii. Artificial Intelligence
viii. Computer Architecture and engineering
ix. computer performance Analysis
x. computer graphics and visualization
xi. computer security and cryptography
xii. computational science
xiii. computer networks
xiv. concurrent, parallel and distributed systems
xv. Databases
xvi. health informatics
xvii. Software Engineering 

what is Software Engineering?

  software Engineering is the study of designing , implementing, and modifying software in order to ensure it is of high quality , affordable, maintainable  , and fast to build .

Deals with organizing and analysing of software. it doesn't just deal with the creation or manufacture of new software , but its internal maintenance and arrangement.

As a software Engineer in the industry .we develop the following applications.

1. Standalone applications
2. Desktop Applications
3. Web Applications
4. Distributed Applications
5. Enterprise Applications.


Application Software or application is a set of computer programs designed to permit the user to perform a group of coordinated functions , tasks, or activities .


Web Application:

A web application or web app is any program that runs in a web browser . It is created in a browser-supported programming language (such as the combination of Java Script, HTML and CSS) and relies on a web browser to render the application.

A web application or web app is an application program that is stored on a remote server and delivered over the internet through  a browser interface.




On web application two categories of programmers start working they are
1. Business content developers
2. web programmers


Distributed Applications:
web application with additional layer called database then it is known as Distributed Applications.
Distributed applications satisfies 3-tier architecture. where as Web applications satisfies 2-tier architecture.

Enterprise Applications:
The process of integrating different types of distributed applications is known as Enterprise/organization applications.

Technologies:
generally we use technologies for
1. Displaying the application in the browser.[UI]
2. getting the data from  the back end[business Logic]
3. manipulating the data come from back end[business logic]
4. sending request and receive response[protocols]
5. server for maintaining user session details
6. web browser for accessing application
7. database for storing data

DATA TYPES & LITERALS DATA TYPES: Every variable in java should have some type. Every expression should have some type and every type is strictly defined. Every Assignment should be checked by the compiler for type compatibility Hence java language is considered as strongly typed programming language Java is a not pure object oriented programming language. Because several OOPs features not supported by java. Like multiple inheritances, operator overloading, etc. Moreover we are using primitive datatypes in java which are not objects Primitive Data types:                                                                  Primitive Datatypes (8) Numeric...

Database Definition and DBMS

Image
Database is a collection of information organized in such a way that a computer program can quickly select desired peices of data.  You can think of database as an electronic filing system. Traditional databases are organized by fields, records and files. an alternative concept in database desing is known as Hypertest . In a Hypertext database any object, whether it be a piece of text, a picture, or a film can be linked to any other object. To access information from the system you need DBMS(database management system) . This is a collection of programs that enables you to  store, modify and extract information from a database. database is used as shorthand for DBMS, there are many different types of DBMSs, ranging from small systems that run on personal computers to huge systems that run on mainframes. few database applications: computerized library systesm, Automated teller machines, flight reservation systems,computerized parts inventory systems.

                                      EVERYTHING ABOUT INTERNET 1.Internet: It is a global network connecting millions of computers. More than 190 countries are linked into exchanges of data, news, and opinions. According to Internet Live stats as of DEC 30 2014 there are 3,037,608,300 Internet users worldwide We generally connect internet through Internet Service Provider [ISP]. Who Owns the Internet? No single person or organization controls the Internet in its entirely. The Internet is more of a concept than an actual tangible entity, and it relies on a physical infrastructure that connects networks   to other networks. Is Web and Internet the Same? The Internet   is   not   synonymous with   World Wide Web . The Internet is a massive network of networks, a networking infrastructure. It connects millions of computers together globally, forming a ...
