Study Notes

Business Information Systems and Computer Networks

  • Computer networks enhance efficiency and productivity by facilitating communication and resource sharing, reducing software costs, and improving storage capacity.
  • Networks automate previously manual tasks like inventory management, accounting, and customer relationship management (CRM).
  • Companies that encourage networking often experience higher employee retention, increased productivity, and enhanced employee development.
  • Networking involves building connections and relationships, offering advice, contacts, and potentially unadvertised job/internship opportunities.

Data Transfer Methods

  • Local data transfer can be wired (Ethernet, USB) or wireless (Wi-Fi, Bluetooth).
  • File Transfer Protocol (FTP) is a standard network protocol for transferring files between client and server computers.
  • Internet connection is required for transferring data between devices; recommended connection is Wi-Fi, but cable is also an option.

Types of Computer Networks

  • Local Area Network (LAN): A network of computers linked within a limited area (e.g., office, school). Uses TCP/IP ethernet or Wi-Fi to connect.
  • Personal Area Network (PAN): Connects electronic devices within a few centimeters to meters (e.g., Bluetooth earpiece and smartphone).
  • Wireless Local Area Network (WLAN): Wireless network within a limited area (e.g., home, office, campus). Often uses Wi-Fi to connect.
  • Campus Area Network (CAN): A network of connected devices across a campus. Features fast and reliable connections, resource sharing, and scalable infrastructure.
  • Metropolitan Area Network (MAN): A network covering a city or a large town. Larger than a LAN, but smaller than a WAN.
  • Wide Area Network (WAN): Connects offices, data centers, cloud applications, and cloud storage over a large geographic area or globally.
  • Storage Area Network (SAN): A network of storage devices, accessed by multiple servers as if local disks.
  • Passive optical local area network (POLAN): Uses optical splitters to distribute data from a single source to multiple user endpoints.

Network Topologies

  • Network topologies describe the physical and logical arrangement of devices and connections in a network, impacting performance, security, and scalability.

  • Repeater: Receives and retransmits signals within a network segment.

  • Switch: Forwards data between devices, unlike routers which forward data between networks.

  • Bridge: Connects two or more network segments allowing communication of devices between separate networks.

  • Router: Sends information between two networks, transferring data between network segments.

  • Point-to-Point Topology: Direct connection between two nodes, using the complete bandwidth of the connection.

  • Bus Topology: All devices connected to a single cable (bus).

  • Ring Topology: Devices connected in a circular manner.

  • Star Topology: Central network processor connects all nodes.

  • Tree Topology: Hierarchical connection between devices.

  • Client/Server: Network configuration with servers and individual computers.
