Summary

TLDRLecture 7 delves into the distinctions between freeware, free software, and shareware, emphasizing their definitions, characteristics, and user freedoms. Freeware, while free to use, is proprietary and lacks source code access, unlike free software which upholds the four freedoms of use, study, modification, and distribution. Shareware offers a trial period but requires a license post-trial, remaining proprietary. The lecture concludes with an assignment to write an essay on the advantages and disadvantages of these software types, highlighting the importance of considering user freedoms and cost implications.

Takeaways

  • 🆓 Freeware is software distributed without a fee, available as fully functional for an unlimited period, but is proprietary and cannot be redistributed.
  • 🔄 Freeware, like Skype or Adobe Acrobat Reader, is free to use but the developer can change future releases to a paid product.
  • 💾 The main difference between freeware and free software is that free software has available source code, allowing users to modify and distribute it.
  • 🏛 Free software emphasizes liberty and freedom, not just the price, and includes the Four Freedoms: to run, copy, distribute, study, change, and improve the software.
  • 📜 Free software can be distributed for a fee under certain licenses, like copyleft, but must always be available for free use, modification, and distribution.
  • 📦 Shareware is proprietary software that offers a trial period, typically 15 to 30 days, after which the user must purchase a license to continue using it.
  • 🚫 After the trial period, shareware expires and users cannot access it without purchasing a license, unlike free software which can be used indefinitely.
  • 🔒 Shareware is not considered free software because it restricts modification and redistribution, and requires a license after the trial period.
  • 🔑 Open source software is different from shareware as it can be downloaded, modified, and used for free without a trial period or license purchase.
  • 📝 The assignment requires students to write a two-page essay discussing the advantages and disadvantages of freeware, free software, and shareware based on their own opinions.
  • 📅 The deadline for the essay is June 14, and it should be formatted in A4 size, 1.5 line spacing, 10 font size, and justified margins.
