Study Notes
Network Basics
- IETF standards documents are referred to as RFC (Request for Comments).
- As data packets move from upper to lower layers in the hierarchy, headers are added.
- The structure or format of data in communication is known as syntax.
- Keyboard communication with a computer involves simplex transmission.
- The first networking framework developed was ARPANET.
- A medium is defined as the physical path over which a message travels.
- The FCC (Federal Communications Commission) oversees interstate and international commerce in communications.
- A switch is not categorized as a network edge device; edge devices include PCs, smartphones, and servers.
- Protocols are the established rules that govern data communication.
- A multipoint connection consists of three or more devices sharing a link.
Network Communications
- A distributed system makes various computers appear as a single coherent system to its client.
- Two devices are considered part of a network if one device can exchange information with a process on another device.
- An overlay network is a network built on top of another existing network.
- In a computer network, nodes can be entities that originate, route, or terminate data.
- A broadcast network is one where the communication channel is shared among all machines.
- Bluetooth exemplifies a personal area network (PAN).
- Routers are devices that forward packets between networks by processing routing information.
- A protocol stack is a list of protocols utilized by a system, with each protocol designated for a specific layer.
Network Management and Access
- Network congestion can occur when traffic overloads the channel.
- A virtual private network (VPN) extends a private network across public networks.
Access Network Technologies
- A low-speed downstream channel is not a component of residential telephone lines.
- DSL (Digital Subscriber Line) telcos typically provide both wired phone access and ISP services.
- DSLAM (Digital Subscriber Line Access Multiplexer) converts analog signals to digital.
- A cable modem termination system (CMTS) is not a term associated with DSL.
- Hybrid Fiber-Coaxial (HFC) networks comprise both fiber and coaxial cables.
- Cable internet access includes characteristics such as being a shared broadcast medium and using HFC technologies.
- Among optical-distribution architectures that function as switched Ethernet, PON (Passive Optical Network) is significant.
