    Study Notes

    Introduction to Information Systems

    • Data consists of raw, unprocessed facts, figures, and symbols
    • Information is data that has been organized and processed to have meaning and context. Data is transformed into information

    Memory Categories

    • Memory stores the operating system and other system software needed for the computer to function
    • It also stores application programs that users interact with
    • Lastly, it stores data currently being processed by the CPU and the resulting information.

    Volatile vs. Nonvolatile Memory

    • Volatile memory loses its contents when the power is turned off
    • RAM (Random Access Memory) is an example of volatile memory.
    • Nonvolatile memory retains its contents even without power
    • ROM (Read-Only Memory) and flash memory are examples of nonvolatile memory.

    Expansion Slots and Adapter Cards

    • An expansion slot is a socket on the motherboard that can hold an adapter card
    • An adapter card is a circuit board that adds functionality to the computer or provides connections to peripherals

    USB Ports and USB Hubs

    • A USB port allows peripherals to connect to the computer and exchange data
    • A USB hub expands the capabilities of a single USB port by providing multiple connection points

    Networks

    • A network is a collection of computers and devices interconnected through communication devices
    • Sharing resources and information are two advantages of using a network
    • Sharing hardware (like printers), facilitating communication, and sharing software applications are advantages

    LAN vs. WAN

    • A LAN (Local Area Network) connects computers and devices within a limited geographic area
    • A WAN (Wide Area Network) spans a larger geographical area, potentially connecting multiple LANs

    Communications Software

    • Communications software facilitates the transmission of data and information between computers or networks
    • It provides an interface for users to communicate with each other (email, chat)

    Modems

    • A modem (modulator-demodulator) converts digital signals from a computer into analog signals, allowing transmission over telephone lines or other communication channels and vice versa. This enables computers to communicate over long distances.

    Routers and Switches

    • A router directs data packets between different networks, determining the most efficient path for transmission
    • A switch connects devices within the same network, enabling direct communication

    Application Software

    • Programs designed for specific user tasks, such as word processing, spreadsheets, or games.

    Binary System

    • A number system using only two digits (0 and 1) to represent all values. The foundation of digital computing.

    CPU (Central Processing Unit)

    • The "brain" of the computer responsible for executing instructions and performing calculations.

    Data

    • Raw, unprocessed facts, figures, and symbols.

    Expansion Slot

    • A socket on the motherboard that allows for the installation of adapter cards to expand functionality

    Information

    • Processed data organized to have meaning and context.

    Memory

    • Electronic components that store instructions, data, and the results of processing.

    Modem (Modulator-Demodulator)

    • A device that converts digital signals to analog and vice-versa, allowing communication over telephone lines.

    Network

    • A collection of interconnected computers and devices that can share resources.

    Operating System

    • System software that manages computer hardware and provides services for application software

    Peripheral

    • An external device connected to the computer, such as a printer, keyboard, or mouse.

    Bit

    • The smallest unit of data in a computer, representing a 0 or 1.

    Byte

    • A group of 8 bits, often used to represent a single character.

    Software

    • Programs that provide instructions for specific tasks for a computer

    System Unit

    • The main case of a computer that houses the motherboard, CPU, memory, and other components

    USB

    • A common interface for connecting peripherals to a computer
