Computer software, or simply software is any set of machine-readable instructions that directs a computer’s processor to perform specific operations. Computer software contrasts with computer hardware, which is the physical component of computers. Computer hardware and software require each other and neither can be realistically used without the other. Using a musical analogy, hardware is like a musical instrument and software is like the notes played on that instrument.
Computer software includes computer programs, libraries and their associated documentation. The word software is also sometimes used in a more narrow sense, meaning application software only. Software is stored in computer memory and is intangible, i.e. it cannot be touched.
Software two major categories: System Software that provides the basic non-task-specific functions of the computer, and Application Software which is used by users to accomplish specific tasks.
System software is responsible for controlling, integrating, and managing the individual hardware components of a computer system so that other software and the users of the system see it as a functional unit without having to be concerned with the low-level details such as transferring data from memory to disk, or rendering text onto a display. Generally, system software consists of an operating system and some fundamental utilities such as disk formatters, file managers, display managers, text editors, user authentication (login) and management tools, and networking and device control software.
Application software, on the other hand, is used to accomplish specific tasks other than just running the computer system. Application software may consist of a single program, such as an image viewer; a small collection of programs (often called a software package) that work closely together to accomplish a task, such as a spreadsheet or text processing system; a larger collection (often called a software suite) of related but independent programs and packages that have a common user interface or shared data format, such as Microsoft Office, which consists of closely integrated word processor, spreadsheet, database, etc.; or a software system, such as a database management system, which is a collection of fundamental programs that may provide some service to a variety of other independent applications.
Software is created with programming languages and related utilities, which may come in several of the above forms: single programs like script interpreters, packages containing a compiler, linker, and other tools; and large suites (often called Integrated Development Environments) that include editors, debuggers, and other tools for multiple languages.

To ensure integration, versatility, transparency and secure collaboration in all of our custom software development projects, EWorld uses a solution that drives efficient software application development by diverse and geographically distributed teams.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/1″][vc_accordion][vc_accordion_tab title=”Architecture Consulting and Design”][vc_wp_text text=”An application architecture strategy is required to sustain a competitive advantage when market demands change rapidly, creating a gap between business requirements and the IT infrastructure. Dynamic market conditions aren’t going to slow down any time soon and the applications architecture must agile enough to support legacy systems as well as new business capabilities.
EWorld provides architecture solutions that align with business objectives and growth strategies. We offer application architecture consulting services that span the entire software product life cycle from legacy systems maintenance to Cloud and Big Data technologies implementation, all backed by our unrivaled industry knowledge and technology expertise. EWorld’s architecture solutions deliver across-the-board improvements to reliability, maintenance and upgrade costs, performance, and scalability.”][/vc_accordion_tab][vc_accordion_tab title=”Software development”][vc_wp_text text=”Nothing affects the quality and achievement of critical business success factors in software as the processes used in the development stage. Application systems today have become so complex that it is no longer feasible to deliver a system using a big bang process. Quality control and the measurement of critical success factors must be applied continuously, with smaller efforts that are delivered frequently.
EWorld applies the principles of continuous integration (CI) and test-driven development (TDD) to ensure that your software initiatives are of the highest quality and will meet your business needs precisely. These processes do more than just ensure a high quality software product; they also keep development costs low by uncovering bugs or incorrect business requirements long before the software is deployed to production.
But it takes more than just a knowledge of development processes and business-driven metrics to deploy a successful software initiative; it also requires a trained and experienced engineering team that can work on a wide variety of platforms, programming languages, databases, and software development technologies. EWorld’s engineers give you that technical edge. EWorld has delivered successful key business projects using the latest technologies.”][/vc_accordion_tab][vc_accordion_tab title=”Performance Engineering”][vc_wp_text text=”Application performance problems can have costly consequences, including diminished productivity, increased customer dissatisfaction, and loss of business growth opportunities. Avoiding these problems and ensuring that your systems meet the highest levels of performance requires more than just careful design, industry standard development practices, and thorough functional testing. Achieving high performance in software requires a planned effort throughout the product life cycle.”][/vc_accordion_tab][vc_accordion_tab title=”Software Quality Assurance and Testing”][vc_wp_text text=”When business models and markets change faster than the applications that support them can be developed, software testing is often first to be cut from the budget or schedule despite the fact that software defects have a direct, negative impact on profitability. Even a small number of defects can have a catastrophic impact on a business, its customers, and its partners. It is estimated that a software defect found and fixed post-production costs 100 times more than if the defect was found in the design stage.
There are many benefits and fewer risks in having an independent software testing partner instead of in-house testing. Independent testers and test consultants bring a much-needed impartiality to the testing processes for better quality, and in-house personnel are freed up to focus on their core business activities. Independent testing brings with it the best-of-breed quality management processes, because that is their core business activity.”][/vc_accordion_tab][/vc_accordion][/vc_column][/vc_row]
