System administrator

A system administrator is like the person who takes care of a big house or building. Just like how the big house has many rooms that people live in, a computer system has many parts and programs that people use.

The system administrator is like the person in charge of making sure everything in the computer system is working properly. They make sure the computer network is connected and working so everyone can use it. They also make sure the programs and software are updated so they work the way they should.

Like how someone might sweep and mop the floors in a house, a system administrator might clean out old or unnecessary files on the computer so it runs smoothly. They also make sure important data, like files and documents, are backed up in case anything goes wrong with the computer.

The system administrator takes care of the computer system, just like how someone takes care of their house to make sure it's clean and functioning properly.
