Network + 1.0

1.1 Explain concepts related to the Open Systems Interconnection (OSI) reference model (Chapters 2,6)

1.2 Compare and Contrast networking appliances, applications, and Functions (Chapter 10)

1.3 Summarize Cloud Concepts and Connectivity Options (Chapter 17)

1.4 Explain common networking ports, protocols, services, and traffic types (Chapter 6, Chapter 8)

1.5 Compare and Contrast transmission media and transceivers (Chapter 3, 4, and 12)

1.6 Compare and Contrast network topologies, architectures, and types

Local Area Network (LAN)

(1.6 Compare and Contrast network topologies, architectures, and types) Restricted to spanning a specific geographical area, such as an office building, a single department within a corporate office, or even a home office.

Metropolitan Area Network (MAN)

(1.6 Compare and Contrast network topologies, architectures, and types) A network covering a metropolitan area used to interconnect various buildings and facilities usually over a carrier provider network. Offer high-speed interconnections using in-ground fiber optics and can be very cost effective for high-speed interconnects.

Wide Area Network (WAN)

(1.6 Compare and Contrast network topologies, architectures, and types) Differ from LANs

• Need a router port of ports

• Span larger geographic areas and/or can link disparate locations.

• Are usually slower

• Can choose when and how long to connect to this.

• Can utilize wither private or public data transport media such as phone lines.

Personal Area Network (PAN)

(1.6 Compare and Contrast network topologies, architectures, and types) Used to collaborate and send data between devices. Is more used with short distance wireless connections such as Bluetooth, Infrared, or ZigBee. Intended for close proximity between devices such as connecting to a projector, printer or a co-workers computer and extend usually only a few meters.

Campus Area Network (CAN)

(1.6 Compare and Contrast network topologies, architectures, and types) Covers a limited geographical network such as a college or corporate campus. Interconnects LANs in various buildings and offers a Wi-Fi component for roaming users. Most offer Internet connectivity as well as access to data center resources.

Storage Area Network (SAN)

(1.6 Compare and Contrast network topologies, architectures, and types) Designed for, and used exclusively by, storage systems. Interconnect servers to storage arrays containing centeralized banks of hard drive or similar storage media. Are usually found in data centers and do not mix traffic with other LANs.

Software-Defined Wide Area (SDWAN)

(1.6 Compare and Contrast network topologies, architectures, and types) A virtual WAN architecture that uses software to manage connectivity, devices, and services and can make changes in the network based on current operations. Integrate any type of transport architectures such as MPLS, LTE, and broadband Internet services to securely connect users to applications. Controller can make changes in real time to add or remove bandwidth or route around failed circuits. Can simplify wide area networking management and operations by decoupling the networking hardware from its control mechanism.

Peer-to-Peer Network

(1.6 Compare and Contrast network topologies, architectures, and types) Network Architecture where computers do not have any central or special authority - they’re all peers, meaning they all have equal authority

Client-Server Networks

(1.6 Compare and Contrast network topologies, architectures, and types) Network Architecture where a single server uses a network operating system for managing the whole network.

Bus Topology

(1.6 Compare and Contrast network topologies, architectures, and types) Topology that consists of two distinct and terminated ends, with each of its computers connecting to one unbroken cable with wire taps,

Mesh Topology

(1.6 Compare and Contrast network topologies, architectures, and types) There is a path from every machine to every other one in the network

Hybrid

(1.6 Compare and Contrast network topologies, architectures, and types)

Star/hub and spoke Topology

(1.6 Compare and Contrast network topologies, architectures, and types) Are connected to a central point with their own individual cables or wireless connections.

Ring Topology

(1.6 Compare and Contrast network topologies, architectures, and types) Each computer is directly connected to other computers within the same network.

Spine and leaf

(1.6 Compare and Contrast network topologies, architectures, and types)

Point to Point

(1.6 Compare and Contrast network topologies, architectures, and types)

Three-tier Hierarchical model (Core, Distribution, Access) a

(1.6 Compare and Contrast network topologies, architectures, and types)

Traffic Flows (North-South, East-West)

(1.6 Compare and Contrast network topologies, architectures, and types)

1.7 Given a scenario, use appropiate 1Pv4 network addressing (Chapter 7, 8)

1.8 Summarize evolving use cases for modern network environments (Chapter 7, 10, 17)
