The First Week of APCSA

In APCSA this first week of school, we learned some of the basics on what a computer is exactly and how it processes information, along with why Java is the preferred language for use. Computers have the ability to store and process data. The user can input data in the form of a program, of which the computer's hardware accesses this data and executes the program. Then, the output device displays the output of the program. The hardware includes the central processing unit, or the CPU, and the memory, stored through Random Access Memory (RAM) and the hard drive. There are two types of languages involved in programming, the high level language and the low level language. Since Java is a high level language, the programs must be compiled into the machine language, or the low level language, which the hardware can understand and utilize to produce an output.
