As the name suggested in manual testing, we do the testing without using any test tools to automate some part to the work. In typical manual testing, you will be given test cases in excel or uploaded to any other tool. Your job is to open the test case and the application under test. Then manually go through each step written in the test cases and perform accordingly.

I found this article very interesting in terms of talking about manual testing in a step by step manner.
