Computers are made up of hardware and software. The physical parts of the computer, for example, the keyboard, printer, connectors and chips, are hardware. The software part of the computer is the collection of programs that make the computers useful. A program is a set of instructions that tells the computer how to perform a task such as how to play solitaire or how to check the spelling of a story you write.
Computer engineers design and build computer hardware.
If you like to solve problems, you might become a successful computer scientist or computer engineer. It is important to think logically and to be able to break a problem up into its parts and to assemble a solution from these parts. These careers also require good communication skills, which are used to define the problem and to document your solutions. Both computer scientists and engineers work primarily in groups that work together to define the problem , establish schedules, brainstorm the solution, and document the results. An individual group member will be responsible for one aspect of the problem.
