what is the difference between information systems and information technology?
Unit 01 – Information systems
Many people use Information Systems and Information Technology as if they meant the same thing. They are different, and it is important for you to understand the difference between them.
As illustrated, an Information System is comprised of two sub-systems, a Social sub-system and a Technology sub-system.

Three elements - hardware, software and telecommunication systems - comprise the technology component of an information system.
Hardware is the physical equipment.
Software is the set of coded instructions (programs).
Telecommunication systems are the networking equipment.
A process is the set of steps employed to carry out a specific business or organizational activity.
In other words, a process maps the set of actions that an individual, a group or an organization must enact in order to complete an activity.
There are multiple viable processes that an organization can design to complete the same activity.
The people component of an information system encompasses all those individuals who are directly involved with the system.
These people include the managers who define the goals of the system, and the users.
Very often, an information system fails because the users do not have enough skills, or have a negative attitude toward the system. Therefore, there should be enough training and time for users to get used to the new system.
The structure (or organizational structure) component of information systems refers to the relationship among the individuals in the people component.
Thus, it encompasses hierarchical and reporting structures, and reward systems. The structure component plays a critical role in an information system, simply because systems often fail when they are resisted by their intended users.
When designing a new information system the organization needs to be cognizant of the current and future reward system in order to create incentives to secure its success.
