Journeying Across the Medium: Embracing Networking 2 Perspective Flashcards
A collection of computers and other devices, including printers, interconnected through various types of transmission media.
Networks
Can range in size from as small as two computers connected by a cable in a home office to the largest network of all, the Internet, composed of billions of computers and various devices interconnected globally through a combination of cable, phone lines, and wireless
links.
Networks
Typically refers to a conceptual or mathematical representation of a network’s structure, behavior, or interactions.
Network model
Fundamental concept in networking that defines how the components of a network are interconnected and how data flows within the network.
Topology
What are the 2 kinds of Topology?
Physical Topology, Logical Topology
Primarily concerns the tangible aspects of a network, specifically its hardware components and the physical layout of devices, cables, and
connections.
Physical Topology
Topology describes how these components are physically arranged and connected to create the actual network structure.
Physical Topology
Common physical topology:
Bus, Star, Ring, Mesh, Hybrid Configurations
Understanding it helps in designing, troubleshooting, and maintaining the network’s physical components, such as identifying potential points of failure or optimizing data transmission paths.
Physical Topology
Focuses on the abstract or logical representation of how data flows within the network, regardless of the physical layout.
Logical Topology
It defines how devices communicate with each other conceptually, regardless of their physical location or the actual cables used.
Logical Topology
Can be implemented
using a mix of desktops, mobile devices, or tablets, regardless of their operating systems.
Peer-to-peer Model
Necessitates one or more Network Operating Systems (NOSes) to manage and regulate network access.
Client-server Model
Are straightforward to
set up and cost-effective compared to other network
types.
Peer-to-peer Model
The resources a network makes available to its users include applications and the data provided by these applications.
Network Services
Applications, which involve two computers,.
Client-server Model
Serves as the centralized directory database that contains user account details and security information for the entire group of computers.
Active Directory (AD)
Each network user possesses a domain-level account, allocated by the network administrator, and maintained within Active Directory.
Client-server Model
Are usually contained in a small space, such as an office or building.
LAN (Local Area Network)
Cover a geographic area larger than a single LAN but smaller than a WAN, such as a city or a large campus.
MAN or CAN
Are networks that span a large geographical area, often connecting LANs across cities, regions, or even countries.
WAN (Wide Area Network)
Typically use long-distance transmission methods, including leased lines, satellite links, and fiber-optic cables. The Internet is the largest and most well-known ____, connecting devices and networks worldwide.
WAN (Wide Area Network)
Are designed for personal
device connectivity within a limited physical area.
PAN (Personal Area Network)
Means that a device is connected directly to the earth, so that, in the event of a short circuit, the electricity flows into the earth, rather than out of control through the device and back to the power station, which can cause an electrical fire.
