Introduction to Computer Software

• Computer software is a collection of programs and data providing instructions for a computer
• It is a conceptual entity including programs, procedures, and documentation for data processing
• The software refers to computer programs and data in computer storage
• Software facilitates human-computer interaction and perform system tasks

Types of computer software

• Application software is designed for end-users, also known as end-user programs that execute user tasks
• Educational software delivers tests and tracks progress for educational purposes
• Enterprise software caters to data flow and organizational processes
• Customer relationship management and supply chain management are examples of enterprise software
• Information worker software manages information for projects or departments with resource management and documentation tools
• Media development software generates print and electronic media and uses image organizers and image editors
• Product engineering software develops hardware and software products with programming interfaces and integrated environments
• Simulation software simulates physical and abstract systems and illustrate scientific concepts and social ideas
• Programming software uses programming languages to write programs that control computer systems
• System software manages and controls hardware so application software perform tasks like transferring data
• Device drivers are computer programs that enable interaction with hardware devices and provide interrupt-handling mechanisms
• Network managers check computer networks, data transfers, and log events
• Virus Scanners scan systems for viruses and is known as antivirus software
• Content-control software controls the content is permitted for user access and restricts content
• Data recovery software supports user needs by backing up important computer data.

Types of Computer Software

• System software helps with computing hardware and operating the computer itself
• The software includes operating systems, device drivers, servers, windowing systems, and utilities
• It helps application programmers abstract away from hardware, memory and complexities
• Application software enables end users to accomplish specific tasks, such as business, databases and educational tasks

Types of Application Software

• Application software directly uses a computer's capacities for dedicated tasks
• Application software can manipulate text, numbers, and graphics with single tasks
• Word processing software such as MS-Word and Notepad enables users to create and edit documents
• Database software relies on organizing data with database software and enable users to retrieve data. e.g., Oracle and MS Access.
• Spreadsheet software simulates worksheets by displaying multiple cells that make up grid and is used for calculations. e.g., Excel
• Multimedia software creates and plays audio and video media with audio converters, players, burners, and video encoders/decoders
• Real Player and Media Player are examples of multimedia software
• Presentation software displays info as a slide show and editing that allows insertion and formatting of text

System Requirements for Software Installation

• Computer software needs certain hardware components or software resources for efficient use
• These prerequisites are system requirements and are used as a guideline
• Software defines sets of system requirements like minimum and recommended specifications
• Minimum specifications are the minimum hardware is required to install and run the OS
• Recommended hardware specifications are what is required to have usable performance
• Recommended requirements represent ideal software running conditions
• It is better to use recommended specifications rather than minimum specifications to fully enjoy software

Hardware Requirements

• Software application or OS often defines physical computer resource requirements
• This is known as the hardware
• A hardware requirements list is accompanied by HCLs (Hardware Compatibility Lists)
• These lists have hardware models and their compatibility with a given operating system
• HCLs list tested, compatible, and incompatible hardware devices for a particular operating system/application

Aspects of Hardware Requirements

• Computer operating systems are designed for specific computer architecture
• Most software applications are limited in operating systems on specific architectures
• CPU (Central Processing Unit) power is fundamental requirement for any software in x86 architecture as model and clock speed
• Many features of a CPU influence speed/power, like bus speed and cache and definition of power is often erroneous
• Software resides in RAM (Random Access Memory) when run and memory requirements are defined in demands
• Hard-Drive vary depending on install size, temporary files while installing/running

Software Requirements

• Software requirements define software resource requirements and prerequisites for optimal functioning
• These requirements/prerequisites need to be installed separately before installing software
• Platform: framework in software/hardware allows software to run e.g: operating system, architecture, runtime libraries etc
• Software may be incompatible when different versions of same operating system even with compatibility
• Software dependent on special hardware devices needs API or newer drivers, example DirectX
• Web applications often depends on default browser, e.g Microsoft Internet Explorer, despite vulnerabilities

Other Software Requirements

• Proper software performance depends on Internet connection type/speed and display screen resolution

Determining Client Requirements

• Installing/upgrading software involving specialized activities and personnel begin with a client request
• The computer support person analyzes the system components for capabilities, processes that manipulate data, current system deficiencies, system constraints, objective, and corporate software
• Hardware, Software determine the appropriate needed components to satisfy information needs and comply with constraints
• Questions to answer include: Is it impossible to solve the problem? Can the organization afford to?
• Aspects to consider are: timeline, cost, technical, legal, and hardware/software/organizational implication
• Variations include: software, licensing, and organizational

Variables for Software and Upgrade Requirements

• Considers software versions, systems, packages, licenses and the client's access

Licensing

• When buying software, actually just receiving a license to use the software
• Validate license for current legal use
• Organizations may have a site license, where any company computer may use software
• Alternatives are, there maybe a limted number of licenses for specific computer
• Factors in organizational license include contracting and purchaser, product licenses, hardware.

Organizational Requirements

• Organization license depends on technology, procedures, suppliers, information, and retrieval
• Common personal computer hardware variables include memory, disk space, CPU
• Includes safety standards to comply with.
• Budget constraints are considered to limit software options

Pre-Requisites

• Current operating system and hardware environment check is required prior to software and upgrades
• Main participants during the software installation. Whether it's new license or software, involves numerous people, varying on degree
