Study Notes
End-User Devices
- End-user devices include computers, printers, scanners, and other devices that provide services directly to the user.
Network Interface Card (NIC)
- A NIC is also called a network adapter or network card.
- The primary responsibility of a NIC is to provide a host device with a physical connection to a network.
Switches
- Switches add control to data transfer management, making it more efficient and reducing data collisions.
Routers
- The primary function of a router is to connect multiple networks together and route data between them.
- Routers are responsible for connecting multiple hosts together.
- The primary role of a router is to determine the best path for data to travel between networks.
LAN Standards
- The primary function of LAN standards is to ensure that hardware and software from different companies are compatible.
Network Classifications
- WAN stands for Wide Area Network, which connects multiple LANs over a larger geographical area.
- LAN stands for Local Area Network, which connects devices in a smaller geographical area.
- MAN stands for Metropolitan Area Network, which connects devices in a city or metropolitan area.
OSI Model
- The OSI Model was created by the International Organization for Standardization (ISO) in 1984 to address the problem of incompatible network hardware and software from different companies.
- The primary responsibility of the Presentation Layer (Layer 6) is to present data in the required format, including code formatting, encryption, and compression.
- The primary responsibility of the Session Layer (Layer 5) is to establish, manage, and terminate connections between applications.
- The primary responsibility of the Transport Layer (Layer 4) is to ensure reliable data transport across the network.
- The Transport Layer is responsible for breaking up the data from the sending host and reassembling it in the receiver, as well as ensuring reliable data transport across the network.
Network Devices
- A hub is a simple network device that connects multiple devices together, but it does not control data transfer.
- Switches differ from hubs in that they add control to data transfer management, making it more efficient and reducing data collisions.
- End-user devices are distinguished from network devices in that they provide services directly to the user, whereas network devices provide services to the network.
