Application facts for kids

The word application has several different meanings depending on how it's used. It can refer to a computer program, a request form, or even how something is used in real life. Let's explore these different uses!

Application in Computers

When you hear "application" in the world of computers, it usually means a computer program. These programs are designed to help you do specific tasks. Think about the apps on your phone or tablet, or the software on your computer. Each one is an application!

For example, a word processing application like Google Docs or Microsoft Word helps you write and edit documents. A web browser application like Chrome or Firefox lets you explore the internet. There are also applications for playing games, editing photos, or learning new things. Each app has a special job it's built to do.

Application in Medicine

In medicine, "application" means putting something on the body. This is usually a drug or an ointment. When you put a cream on your skin for a rash, you are "applying" it. The medicine then gets absorbed into your human body to help you feel better.

Doctors and nurses often talk about the "application" of medicine. This means making sure the medicine is put on the right place and in the right way. It's a key part of how many treatments work.

Application for Jobs or Services

Have you ever heard someone say they filled out an "application" for a job or a school? In business or government, an application is a formal request. It's often a paper or online form that a person fills out.

People use applications to ask for many things. You might fill out an application to get a job, to get credit to buy something, or to get a license or permit for something like driving. You might even fill out an application to get a place to live. It's a way to officially ask for a privilege or service from a state or a company.

Application in Engineering and Materials

In fields like engineering, "application" can mean the specific way a material or object is used. It's about the purpose something serves. For example, wood can be used for building houses, making furniture, or creating art. These are all different "applications" of wood.

Similarly, steel has many applications. It can be used to build tall skyscrapers, make cars, or create tools. Understanding the different applications of materials helps engineers choose the best ones for their projects.
