Tingkat-tingkat Abstraksi Organisasi Komputer
° Application S/W• MS Word computer as electronic type-writer
• MS Excel computer as electronic calculator
° System S/W• Compilers computer as translator (source to executable
program)
• Operating Systems computer as machine that executes programs, stores files, prints content of files to printers, communicate with other computers
° Instruction Set• What basic operations can be carried out
• What, where, and how data can be stored & retrieved in/from memory
• How can data be exchanged to the outside “world”
° Computer H/W• The 5 components: Datapath, Control, Memory, Input, Output
