Tech Differences

The algorithms are designed using two approaches that are the top-down and bottom-up approach. In the top-down approach, the complex module is divided into submodules. On the other hand, bottom-up approach begins with elementary modules and then combine them further. The prior purpose of an algorithm is to operate the data comprised in the data structure. In other words, an algorithm is used to perform the operations on the data inside the data structures. A complicated algorithm is split … [Read more...]

There are three types of access protection defined in C++ programming language for hiding the data. Data hiding is an essential part of the object-oriented programming. The private and protected keywords offer the level of access protection to hide the data and function within a class. The private members cannot be inherited while the protected member can be inherited but in a limited range. These specifiers indicate the visibility of the members where private is more restrictive than … [Read more...]

Abstraction and Data hiding are the crucial concepts of the object-oriented programming. Abstraction is a method of expressing the important properties without involving the background details. On the other hand, Data hiding insulates the data from the straight access by the program. Although, both the concepts sound similar in the sense but are different. The abstraction provides a way to create user-defined data types for designing real-world objects having same properties. As against data … [Read more...]

The CGI and Servlet are the programs which reside within the web or application server and assists the communication between the web server and the browser (client side) to generate the web content dynamically. CGI and servlet can be differentiated because they work in different manners and have distinct functionality and features. The CGI (Common Gateway Interface) programs can be designed in the native OS and kept in particular directory. On the other hand, the servlet is a web component which … [Read more...]

XML and HTML are the markup languages defined for the distinct purposes and have several differences. The prior difference is that in XML there are provisions for defining new elements while HTML doesn't provide a specification to define new element and it uses predefined tags. XML can be used to build markup languages while HTML itself is a markup language. HTML (Hypertext Markup Language) was designed to facilitate the transfer of web-based documents. Conversely, XML was developed for … [Read more...]

Syntax and Semantics are very significant terms relating to any programming language. The syntax in a programming language involves the set of permitted phrases of a language whereas semantics expresses the associated meaning of those phrases. There are some relationships between syntax and semantics where each semantic element is linked to at least one syntactic rendition and the other one assures that each syntactic representation has a distinctive meaning. Content: Syntax Vs Semantics … [Read more...]

Cellpadding and Cellspacing are the attributes used in table formatting, it actually sets the whitespaces in your table cells. These are the significant properties of a web document. The main difference between cellpadding and cellspacing is that the cellpadding is used to fix the width between the cell edge and its content. Conversely, the cellspacing sets the space between the single cells. The width of these attributes can be measured by using pixels or percentage. For adjusting the space … [Read more...]

GET and POST are two efficient techniques that can send the data to the server and browser necessarily need these to communicate to the server. The two methods are distinct where GET method adds the encoded data to the URI while in case of POST method the data is appended to the body rather than URI. Additionally, GET method is used for retrieving the data. Conversely, POST method is used for storing or updating the data. The form tag is used for expressing the content of the form; this is … [Read more...]

Java and JavaScript are the programming languages primarily used for the different purposes. Although they sound similar but there are not many similarities between them, in fact, they are different. Java is essentially be used as a general-purpose programming language while JavaScript is used as client-side scripting language. Java is both compiled and interpreted language while the browser interprets JavaScript. The JavaScript uses prototype objects, and these objects help in accessing … [Read more...]

The scripts can be written in two forms, at the server end (back end) or at the client end (server end). The main difference between server-side scripting and client-side scripting is that the server side scripting involves server for its processing. On the other hand, client-side scripting requires browsers to run the scripts on the client machine but does not interact with the server while processing the client-side scripts. A script is generally a series of program or instruction, which … [Read more...]
