Study Notes

Software Overview

  • Software is a set of instructions that tell a computer what to do.
  • Software is categorized into system software and application software.

System Software

  • System software manages the computer's hardware and applications, and manages its resources such as memory, processors, and devices.
  • System software provides a platform to run application software.
  • It's typically bundled with the computer's operating system.
  • Types include utilities, operating systems, and programming software.

Application Software

  • Application software performs specific tasks for the user by interacting directly with the user.
  • It helps users to complete specific tasks, manage and manipulate data, and effectively organize information.
  • It's categorized into a variety of functions including word processing, spreadsheet, presentation, multimedia, web browsers, educational software, graphics and more.
  • Examples include Microsoft Word, Microsoft Excel, PowerPoint, and various browsers (like Chrome or Firefox).
  • Also includes software for specific tasks such as healthcare (EHR, EPS), education (Docebo, Classroom), or general tasks such as email, text messaging, videoconferencing.

Programming Software

  • Programming software helps programmers develop other software and is used to create computer code to allow computer software to operate.
  • It includes compilers, assemblers, debuggers, and interpreters.
  • Programming software has a history starting in the mid-1800s.
  • Examples include languages like C++, C#, Python, PHP, Java, and JavaScript.

Malicious Software

  • Malicious software, or malware, is any malicious program that causes harm to a computer system or network.
  • This includes viruses, worms, trojans, spyware, adware, and rootkits.
  • Malware attacks computers or networks in different ways, like downloading, websites, emails, and file-sharing.
  • Prevention strategies include keeping software updated, being cautious about downloads, and using antivirus software.

Careers in IT

  • Computer support specialists provide technical support to computer users, resolve common problems, and use troubleshooting tools.
  • Job duties include providing help and support, and diagnosing problems.
  • Computer support specialists often have associate or bachelor's degrees and require skills in analytical, customer service, communication, and people skills.
  • Self-healing computers can fix software problems and reroute functions around hardware failures.
  • The use of APIs (application programming interface) allows access to new services and products without building it themselves, this is known as the API Economy.
  • Automation of software delivery (Continuous Integration and Delivery) leads to faster software releases and improved efficiency.
  • The internet of things (IoT) is a rapidly growing field, and continues to change.
  • There is substantial growth in the fields of edge computing, quantum computing, big data, and augmented reality (AR).
  • Low-code/no-code platforms are helping to make software development more accessible to those outside of IT.
  • Artificial intelligence (AI) continues to dramatically impact software development. Machine learning-based technologies are being applied and used every day.
