Cheat Sheet
- Core Definition -
Understand that a communications system connecting two or more computers describes any arrangement where devices exchange data over a shared medium, such as Ethernet cables or Wi-Fi channels. This foundational concept, defined in ISO/IEC 7498-1, is the bedrock of computer network fundamentals and ensures clear data flow between endpoints.
- OSI Model Layers -
Memorize the seven layers of the OSI model - Physical, Data Link, Network, Transport, Session, Presentation, and Application - using the mnemonic "Please Do Not Throw Sausage Pizza Away." These network communication basics help you map real protocols like TCP/IP (Transport and Network) and HTTP (Application) to their corresponding layers.
- Switching Methods -
Differentiate packet switching (used in the Internet, where data is sent in discrete chunks) from circuit switching (used in traditional telephony, where a dedicated path is reserved). Remember that packet switching offers better resource utilization, while circuit switching guarantees constant bandwidth - key concepts for a data communication systems quiz.
- Essential Network Devices -
Review the roles of NICs (Network Interface Cards), switches, and routers: a NIC connects a host to the network, a switch forwards frames within a LAN, and a router directs packets between different networks. These components are pillars of computer network fundamentals, ensuring seamless data delivery at each hop.
- IP Addressing & Subnetting -
Practice converting IPv4 addresses with slash notation (e.g., 192.168.1.0/24) to binary masks to master subnetting for your online systems and networks test. Understanding how to calculate network and host portions boosts your confidence in tackling real-world scenarios and exam questions alike.
