โ What is a bit? What is a byte? Answer: A bit is a binary digit 0 or 1. A byte is a sequence of 8 bits. โ What is memory for? What does RAM stand for? Why is memory called RAM? Answer: Memory is like a work area for programs. Before a program is executed, it is brought into the memory. RAM stands for random- access memory. It is called RAM because a memory cell can be accessed directly. โ What unit is used to measure memory size? What unit is used to measure disk size? Answer: Memory size is measured in bytes. Disk size is measured in bytes. โ What is the primary difference between memory and a storage device? Answer: Memory is volatile, because information is lost when the power is turned off. Programs and data are permanently stored on storage devices and are moved, when the computer actually uses them, to memory, which is much faster than storage devices. โ What language does the CPU understand?
Answer: The machine language is a set of primitive instructions built into every computer. This is the language understood by a computer and executed by a computer. โ What is an assembly language? What is an assembler? Answer: Assembly language is a low-level programming language in which a mnemonic is used to represent each of the machine language instructions. Assembler is a software that translates assembly language into machine language. โ What is a high-level programming language? What is a source program? Answer: The high-level languages are English-like and easy to learn and program. The program written in a programming language is called a source program. โ What is an interpreter? What is a compiler? Answer: An interpreter is a software that reads one statement from the source code, translates it to the machine code or virtual machine code, and then executes it right away. A compiler is a software that translates a program in high-level language into machine language code.
