Concept
Retail software is computer software, typically installed on PC-type computers post 2005, delivered via the Internet (also known as cloud-based). Traditionally this software was delivered via physical data storage media sold to end consumer but very few companies still provide their software using physical media. The software is typically sold under restricted licenses (e.g. EULAs) or in the case of cloud-based software sold as a Software-as-a-Service (SaaS) model. Cloud-based software: this is software that is not installed on a user's device but delivered on-demand via the Internet to the end user's device(s) either through web-based apps or native apps (iOS and Android). Most new software companies provide both or a combination of web, and native apps which may provide different functionality depending on the actual user in a client company. OEM Pack -HOW This is a licensed copy of software given by the software manufacturer to a computer manufacturer to pre-install on a computer being sold to a customer. A backup copy may or may not be provided on a CD to the end-user along with the computer. Box Pack - This is a licensed copy of the software that an end-user buys off the shelf from any authorized retail outlet. They may sometimes be more highly-priced than OEM versions as you generally get additional software along with the main software within the pack. Paper License - This is a scheme provided by the software manufacturer to companies or businesses that require many copies of particular software to be installed on multiple computers within the organization (Volume license key). Say, for example, a company requires installing software on 50 computers in its office. Instead of buying 50 CDs and managing those 50 individually, the company can buy one copy of the software and request the software vendor to issue a paper license authorizing them to use it on 50 computers. The software vendor then charges them accordingly. This method is also much cheaper than buying 50 individual packs.
