    Study Notes

    Networking Fundamentals

    • The OSI model was developed by the International Organization for Standardization (ISO).
    • An IPv4 address is 32 bits long, which is equivalent to 4 bytes or 12 digits.

    Network Addressing

    • A DNS (Domain Name System) server is used to resolve domain names to their corresponding IP addresses.
    • A MAC (Media Access Control) address is a unique identifier assigned to a network interface controller (NIC) for a computer.
    • ARP (Address Resolution Protocol) is used to convert an IP address to its corresponding physical address.
    • RARP (Reverse Address Resolution Protocol) is used to obtain the IP address of a device given a physical address as input.
    • DHCP (Dynamic Host Configuration Protocol) has replaced BOOTP (Bootstrap Protocol) which has become obsolete.

    Computer Networks

    • The "Networking Essentials" course covers the basics of networking concepts for complete beginners.
    • Computer networks are a collection of interconnected devices that communicate with each other to share resources.
    • A LAN (Local Area Network) is a computer network that spans a small geographic area, typically within a building or campus.
    • A WAN (Wide Area Network) is a computer network that covers a larger geographic area, such as a city or country.
    • The largest example of a WAN is the internet.

    Network Devices

    • A router is a network device that connects multiple networks together and routes traffic between them.
    • A router's main function is to direct traffic between networks.
    • Additional features of a router may include firewall capabilities, network address translation (NAT), and quality of service (QoS) management.

    Network Communication

    • Communication and data exchange between connected computers are enabled through the network.
    • A network topology is the physical and logical arrangement of devices and connections within a network.
    • The OSI model's seventh layer (Application Layer) is responsible for specifying standards for communications protocols.

    Network Ports and Sockets

    • A computer system has 65535 available ports.
    • A socket is a endpoint for communication between two devices (computer, phone, etc) in a network.
    • DNS servers are used to identify the IP address of a domain.

    Network Purpose

    • The purpose of a computer network is to enable communication, data exchange, and resource sharing between connected devices.
    • The internet is a global system of interconnected computer networks that enables communication, information sharing, and connectivity for various purposes.
