Study Notes

Network Fundamentals

In datagram switching, the total delay includes queuing time, processing time, and transmission time.
A point-to-point WAN (Wide Area Network) is a type of link.
WANs operate in the network category.

LAN Topologies

Common topologies for local area networks include bus, star, ring, mesh, and hybrid.

Network Devices

NIC stands for Network Interface Card in the context of networks.
The primary purpose of a Wide Area Network is to connect multiple LANs.

Packet Switching

In packet switching, data transfer uses a store-and-forward method.
Packet switching networks only accept packets with a maximum size.
Longer messages are transmitted by breaking them into smaller packets.
Each packet includes source and destination addresses, packet length, and packet sequence number.
Redundant connections in a switched network improve reliability.

MAC Addresses

A MAC address with the first hexadecimal digit being 4 is a unicast address.
A MAC destination address with all bits set to 1s in Ethernet represents a broadcast address.

Switches and Bridges

A device that operates in a single collision domain is a switch.
A transparent switch (bridge) forwards frames based on MAC addresses.
Transparent switches build a table using a technique called learning.
Full duplex supports simultaneous transmission and reception.
A repeater's primary function is to amplify and extend network signals.

Network Devices

A router connects multiple networks and routes traffic between them.
A hub's primary function is to repeat incoming signals to all connected devices.
Bridges differ from routers in that they connect multiple networks at the data link layer.
The primary purpose of a routing table is to store routes for packet forwarding.

IEEE 802.2

The Logical Link Control (LLC) sublayer provides flow control and error detection services to the network layer.
The Medium Access Control (MAC) sublayer manages data transmission and reception.
In an 802.3 MAC frame, the preamble and start frame delimiter (SFD) synchronize the receiver.
The primary function of the MAC sublayer is to manage access to the medium.
In an 802.2 MAC frame, machines are identified by unicast addresses.
The LLC sublayer provides a best-effort delivery service to the network layer.
