Chapter 3How computers process informationComputers are constantly processing large amounts of information. Operating a computer involves sending and receiving complex sets of instructions. Computers have their own language, called machine language. Machine language is made up of binary digits that are represented by the numbers 0 and 1. Every possible （ 1 ） operation is encoded with different combinations of these two numbers.However, programmers usually do not send commands in machine （ 2 ）. They write software in human-readable programming languages. This allows programmers to write software quickly and efficiently. These languages, like C and Java, are more compatible with the way （ 3 ） think. However, computers still require instructions in machine language.Systems software facilitates this communication within the computer. A （ 4 ） is a software component that translates human-readable language into an assembly language. This language is simpler than a human-readable language. But it still uses letters and words. The computer needs an assembler to turn those instructions into the （ 5 ） translation.For example the programmer might write the command“A ＋ B. ” Then, a compiler converts it into an assembly language: “Add A,B.” Finally, an assembler translates it into machine language: “1000110010100000. "The computer uses these instructions to perform the command.
