The following article explains What is a JSP Tag.

Basically, JSP tags are a set of predefined Java tags that are used to perform various tasks in a JSP page. Further, JSP tags are divided into three categories.

  1. Standard tags. These are a set of predefined tags provided by Java EE that can be used to perform tasks such as iteration, conditionals, and variable assignment. For example.
<c:forEach items="${employees}" var="employee">
<tr>
<td>${employee.name}</td>
<td>${employee.age}</td>
<td>${employee.salary}</td>
</tr>
</c:forEach>

2. Custom tags. These are user-defined tags that can be created to perform specific tasks on a JSP page. Custom tags are typically used to extend the functionality of JSP pages beyond what is provided by the standard tags. For example.

<my:customTag param1="value1" param2="value2" />

3. Expression Language (EL) tags. These tags are used to evaluate expressions and perform operations on a JSP page. EL tags are used to access data stored on the JSP page or in the application’s data model. For example.

${employee.name}

to summarize, JSP tags are an important part of JSP development, as they provide a powerful and flexible way to perform various tasks in a JSP page. Therefore, by using JSP tags, developers can modularize their code, improve code readability and maintainability, and extend the functionality of JSP pages beyond what is provided by the standard Java EE tags.
