About Software-as-a-Service (SaaS):

SaaS is a cloud-based method of delivering software where users subscribe to access applications on the Internet rather than purchasing them outright.
The software is located on external servers rather than on servers located in-house.
SaaS vendors host services and applications for customers to access on-demand.
These services are available to end-users over the internet, so the end-users do not need to install any software on their devices to access these services.
Common SaaS examples include email, calendaring, and cloud-based collaborative tools like Slack.
This model operates similarly to streaming services, offering flexible, subscription-based access from any compatible device.
By hosting the software in the cloud, SaaS provides a complete solution that enhances accessibility and convenience, allowing users to connect and use these apps on a pay-as-you-go basis.
The SaaS model shifts the burden of maintaining and hosting the software to the SaaS provider.
This shift results in substantial benefits, such as consistent maintenance, robust security, and guaranteeing that the software remains continuously accessible and current.
This setup allows businesses to focus on their core activities without worrying about the technical complexities of software management.

Q1: What is software?

Software is a set of instructions, data, or programs used to operate a computer and execute specific tasks. In simpler terms, it tells a computer how to function. It’s a generic term used to refer to applications, scripts, and programs that run on devices such as PCs, mobile phones, tablets, and other smart devices. This contrasts with hardware, which is the physical aspects of a computer that perform the work.
