What is the process of writing specific instructions in computer language called?
A machine code program. Machine code is the native language of the machine and the only language actually understood by the machine. However, program instructions can be written using a high-level programming language that the computer can translate into machine code using another machine code program called a compiler.
What are the four distinct actions that a machine instruction can specify?
• The processor fetches the instruction from memory • Program counter (PC) holds address of the instruction to be fetched next • PC is incremented after each fetch • Fetched instruction loaded into instruction register
What is the difference between program and process?
Program is a set of instruction whereas process is program in execution. Program is passive entity whereas process is active entity .Program has single instance whereas process has several instances.For eg.several notepad windows can be opened but same program is executed behind each window. Program is dependent on logic used whereas process is dependent on program.
What does it mean to say that a computer understands a program?
The only part of a program a computer understands is each instruction as it is presented to the instruction decoder. It understands the instruction by an intricately designed logic circuit and/or microprogram configured by a human computer hardware engineer. This engineer had to fully understand the instruction set of the machine to teach it to understand the instructions one at a time at runtime.

Why is assembly language considered easier for humans to program than machine language?
Assembly is signficantly shorter and easier to remember than the equivilant machine instructions. Assembly instructions are human readable characters, for which a direct translation exists to the binary machine code instructions. Pseudo example: add <- assembly instruction 1010101010 <- machine instruction
What is the fetch-decode-cycle on a computer?
when we execute a program, the starting address is loaded in the program counter. Then for each instruction the processor goes through fetch-decode-execute states. At the fetch state the instruction code is fetched then decoded to understand what exactly has to be done. Then finally it executes that instruction. This process goes on till it reaches the end of the program.
