    Key Takeaways

    • Software gives the instructions that tell the hardware what to do.
    • There are two basic categories of software: operating systems and applications
    • Operating systems interface with the computer hardware and make system resources available
    • Application software focuses on the work of a user or an organization.
    • Desktop applications are typically designed for a single user. Enterprise software supports multiple users in an organization or work group.
    • Cloud computing provides access to software and databases from the Internet via a web browser.
    • The software as a service (SaaS) category of cloud computing gives companies access to a large assortment of software packages without having to invest in hardware or install and maintain software on its own computers.
    • Shifting IT functions to the cloud produces a number of advantages, including cost savings, speedy delivery of software, scalability (you pay for only what you need), employee mobility, and a reduction in information technology staff.
    • The following disadvantages of cloud computing are cause for concern: disruption in internet service, security issues, and unreliability of service provider systems.
    • Software can be built (proprietary) or purchased (off-the-shelf).
    • Open source software is software where the source code is available for anyone to copy and use.
