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
