    Study Notes

    Basic Network Concepts

    • A bit is a basic unit of information representing one of two discrete states.
    • A byte consists of 8 bits.
    • A server is a computer with software providing information like emails or web pages to other devices.
    • A roll-over cable is another name for a console cable, used to connect a computer to a console.
    • NFC (Near Field Communication) is a wireless technology enabling a consumer to pay at a store using a smartphone near a pay terminal.
    • Packet forwarding is when a router directs data packets destined for networks not directly connected to it.

    IP Addresses

    • Private IP addresses cannot be used on the public internet.
    • DSL is an internet service providing high-speed digital transmission over existing phone lines.

    Networking Concepts

    • DHCP is a protocol that automatically assigns IP addresses to devices on a network.
    • Link-local addresses are used for communication within the same local network (not on the internet).
    • Network administrators improve network security and manageability by dividing a network into smaller networks (subnets).

    Network Troubleshooting

    • Structured troubleshooting methods (e.g., replace method) systematically solve problems by testing different components as possible causes of a problem.

    Computer Networking

    • Routers are core network devices that forward packets between networks.
    • MAC addresses identify physical network devices.
    • Logical addresses (IPv4 or IPv6) are used to locate a network device.
    • TCP/IP protocols define standards for data transmission. These protocols ensure data is sent reliably and in order.
    • ARP translates IP addresses to corresponding MAC addresses within the same network.
    • A broadcast address directs a message to all devices on a network.
    • A default gateway is required for a device to communicate outside its local network. This means the request must go via a router.
    • ARP tables on networks maintain a mapping of IP addresses to MAC addresses on the local network.
    • Ethernet frames contain data for network communication,
    • Network data frames typically have a maximum size limit which defines how much data can be encapsulated in the frame.

    ###Network Components

    • Ethernet cables are a common way to connect devices in a wired network
    • Network switches connect devices and forward traffic between them based on their MAC addresses.
    • A router connects different networks and facilitates communication between them.
    • A Mobile Hotspot creates a small network accessible to mobile devices.
    • DSL is an internet service that transmits over existing phone lines.

    Networking Devices

    • Servers provide services like hosting websites and email to other devices on the network.
    • Routers are network devices that forward data between different networks and determine the path that the data should take.
    • Computers are network devices used to handle operations and data.
    • Wireless access points (like routers) create a wireless network.
