CP102 Chapter 2: Texbook Notes
Document Summary
A computer is a data processing device that performs four major functions: Binary: the language of computers: everything a computer does, such as processing data, printing a le or editing a photo is broken down into a series of 0s and 1s. Each 0 and 1 is a binary digit, or bit for short: eight bits combine to create one byte. Kilobytes, megabytes, and gigabytes are therefore simply larger amounts of bytes. A kilobyte (kb) is approximately 1,000 bytes, a megabyte (mb) is about 1 million bytes, and a gigabyte (gb) is around 1 billion bytes. How does a computer keep track of bits and bytes: computers only understand two states of existence: on and o . What are integrated circuits: tiny regions of semiconductor material that support a huge number of transistors, this advancement has enabled computer designers to create small yet powerful microprocessors, which are the chips that contain a central processing unit (cpu, or processor).
