Knowledge and skill are both related to a person learning ability. Knowledge can be learned. For instance, if a person goes to school for cosmetology, they have knowledge about it. Skill is applying that knowledge, so for a cosmetologist, the skill would be cutting a person's hair.
Knowledge is learned. It can be learned through a traditional school setting or through life experiences. Skill is applied through action. It is putting the knowledge learned into actions that produce results.
Another example to differentiate between the two is a person going to law school to be a lawyer. In school, they are learning the knowledge to be effective. The skill would be them defending a client in court.
There are a lot of people who are aware that knowledge and skill are very important, but they are not sure how they are different. When you say knowledge, this stands for the information that you may have in your head about different things.
There may be some things that you would need to know how to do. The information can be very important for sure. Skill means that you are going to put into action the things that you have learned.
The knowledge that you have will be put to the test when you are going to start using your skills in order to work on different tasks. There are a lot of skills that you can use for sure. Depending on how well the application is going to be, the better your skills are.
