Study Notes

Introduction to Computing

  • A computer system is a group of devices (hardware, software, and liveware) designed to manage, process, receive and display data in a clear way.
  • Hardware includes tangible and intangible computer components that facilitate input, processing, output, secondary storage, and communication.
  • Software is also referred to as programs or apps, divided into system software and application software.
  • Liveware, also called humanware or orgware, is the person who uses the computer.

Hardware Categories

  • A computer system comprises interconnected devices that handle input, output, processing and storage of data.
  • Input, processing, storage, output, and communication devices are the five main components of computer hardware.

Hardware Components

  • Central Processing Unit (CPU): The CPU is the "brain" of the computer, performing calculations and commands.
  • Memory (RAM): RAM is temporary storage for information and commands needed by the CPU for quick access.
  • Input/Output Devices: These devices allow data input and instruction entry into the computer.
  • Storage Devices: Hard drives and solid-state drives provide long-term data storage, enabling data retrieval even without power.
  • Motherboard: This component connects and facilitates communication between computer parts.
  • Power Supply: Delivers power to all computer components.
  • Cooling systems: Computers use fans or liquid cooling to prevent overheating and potential hardware damage.
  • Network Interface Card (NIC): Hardware enabling computer connection to a network and communication with other networked devices.
  • Peripherals: These are extra devices (e.g., external hard drives, printers, scanners) that enhance computer functionality.

Software Components

  • Operating System (OS): Manages computer hardware and software resources, including storage, memory, and input/output devices.
  • Applications: Specific tools (e.g., word processors, browsers, video games) used to perform tasks.
  • Drivers: Special software that allows the operating system to interact with hardware components.

Memory

  • The processor performs fundamental computer system calculations. Other components assist by storing and moving data in and out of the processor.
  • Processor chips have limited memory (RAM) for a few program instructions and the data they process. Complete programs and data are stored in external memory.
  • Types of external memory include main (RAM/primary) and secondary (long-term storage).

Main Memory

  • Main memory is sometimes called volatile storage as it loses information when power is removed.
  • Main memory is closely connected to the processor.
  • Data in main memory can be quickly and easily changed, holding programs and data the processor actively uses.
  • Main memory requires constant power to retain information.

Secondary Memory

  • Secondary memory (e.g., hard drives, solid-state drives) stores programs and data long-term.
  • Secondary storage also is called mass storage.
  • Data in secondary memory is easily changed but slower than main memory.
  • Secondary memory does not need constant power.

Networks

  • A computer network connects two or more computers to exchange data and programs.
  • Local Area Networks (LANs): Connect a few dozen computers within the same building.
  • Wide Area Networks (WANs): Connect thousands of computers over long distances via optical fiber, telephone lines, microwave radio, or satellite communication.

Internet Protocols

  • Internet protocols are rules enabling computers and devices to communicate over the internet.
  • Protocols ensure correct sending, receiving and understanding of data between systems.
  • Examples include TCP/IP (assigns unique IP addresses), SMTP (email), FTP (file transfer), and HTTP (hypertext transfer).
