Data Compression is a Great Way to Reduce Data Size

Data Compression

The process which reduces data sizes, by removing excessive information is known as data compression. The size of a file is reduced, in order to save space, save time and reduce redundancy, during compression. A number of data compression algorithms exist, in order to compress different types of data formats. All the images we see online, are typically compressed in the JPEG or GIF formats, and file systems also compress files automatically. When files are stored and for those large files, that don’t automatically get compressed, we do it ourselves.

Converting A Binary Number to Decimal and to Hexadecimal


In order to be able to convert a decimal number to binary, one must have a basic understanding of the decimal, binary and hexadecimal numbering systems. Decimal numbers are used often in mathematics, and are 10 digits (0 - 9), which occupy a decimal place. Binary numbers are 1s and 0s to us, but to computers the number one represents the high or on setting and the number zero, would mean low or off setting in a computer. Binary is used in order to represent computer data, and it can be grouped together into bytes.

The Agile Software Development Methodology - Overview

Agile Software Development

On the article written by Hobbs and Petit, they explain that the agile software development methodology, has been gaining popularity, since the 2000s, and have taken software development by storm. In an agile environment, small collocated teams, work on small, non- critical, green field, in-house projects, this was identified by Kruchten as the “agile sweet spot”. The architecture of these projects is stable, and the rules of governance are simple; therefore, the agile methodology is being used more and more on larger projects, according to Hobbs and Petit.

Introduction to Waterfall Methodology


The development phase of an application, have always followed a waterfall method, but later the agile method was also adopted. As one of the oldest methods used, to develop a software, the waterfall methodology, remains the most used among software engineers and developers. Developers and software engineers, follow a sequential model, which goes downward, going through different phases, when they use the waterfall method. Requirement gathering and analyses, design, coding, testing and maintenance, are the phases, which are part of the waterfall methodology.

A List of The Different Types of Stand Alone Computers

Symbols can be manipulated through machines known as computer systems, which are functional computers with all its hardware and software, made to help users achieve their goals, complete tasks and solve problems.

Computer systems can be categorized based on a variety of factors however on this post, I will use the size and the power of the computer systems to categorize this list.

Computer systems can be categorized as follows, from the largest and most powerful computer systems to the smallest and least powerful computer system we use today:

Test Driven Development has Revolutionized the Software Development Life Cycle Part II

The programming arena is plagued with many issues, which developers can solve, when they follow a software development methodology, which suites the project.

In today’s article we are going to talk about the Test-Driven Development (TDD) methodology, in order to understand this software development method.

As a software development process, TDD relies on the repetition of a very short development cycle.

An automated test case, which defines a desired improvement or new function, is first written by the developer.

Test Driven Development has Revolutionized the Software Development Life Cycle

In the programming arena, developers have to work in the dark, which is very similar to walking in a dark house from room, to room to understand what each room can do, and use that room for a specific purpose.

When developers write the test for code, before developing features for an application, they can improve on the quality and productivity of the software development life cycle; it’s like switching on the lights in the dark room.

The Seven Principles of Lean Software Development

The computer world, is taking over the world, due to the software development processes, which have been changing on a daily basis.

In today’s article, we are going to talk about, the lean software development methodology, in order to understand, how software development is done.

The seven principles of lean software development methodology are: Eliminate waste, which helps software developers eliminate activities, which do not directly add value to the finished product.

EXtreme Programming Methodology is The Most Effective Methodology in Software Development

Extreme Programming

The world of computers is amazing, and unless you are a person who is willing to go through to be thrown into parts of the world of computers, which does not feel amazing, then you will never be able to see, or experience the amazing part of the world of computers.

In today’s article, we are going to talk about, Extreme Programming or XP methodology, in order to fully understand this methodology and its inner workings, in a software development environment.
