Examining Network Topologies and Traffic Flows, and Networking Protocols and Services

Physical Topology

The actual physical layout of a network's components and connections.

Logical Topology

The way data flows through a network, regardless of its physical layout.

Star Topology

A network topology where each node is connected to a central device.

Bus Topology

A linear network topology where all nodes share a single communication line.

Ring Topology

A network topology where each node is connected in a circular format.

Mesh Topology

A network where every node is connected to every other node, allowing for multiple pathways.

Hybrid Topology

A combination of two or more different types of network topologies.

North to South Traffic

Traffic that flows from external networks into your internal network.

East to West Traffic

Internal traffic between systems within the same network.

Zero Trust Security Model

A security concept that assumes threats could be inside or outside the network, requiring verification from everyone.

Client-Server Model

A network model where clients request services from centralized servers.

Peer-to-Peer Model

A network model where each device can function as both a client and a server.

Transport Layer Protocols

Protocols like TCP and UDP that define how data is sent over a network.

DHCP

Dynamic Host Configuration Protocol, used for automated IP addressing.

HTTP

Hypertext Transfer Protocol for transmitting web pages.

FTP

File Transfer Protocol, a standard network protocol used for transferring files.

SMTP

Simple Mail Transfer Protocol, used for sending emails.

IMAP

Internet Message Access Protocol for retrieving emails from a server.

POP3

Post Office Protocol version 3, used for receiving emails.

DNS

Domain Name System, translates domain names to IP addresses.

SNMP

Simple Network Management Protocol for managing devices on IP networks.

LDAP

Lightweight Directory Access Protocol for accessing and managing directory information.

RDP

Remote Desktop Protocol, allows remote access to a computer.

SIP

Session Initiation Protocol, used for starting and managing VoIP sessions.

SQL

Structured Query Language, used for database management.

SMB

Server Message Block, a protocol for sharing files and printers in Windows.

NTP

Network Time Protocol, used to synchronize clocks over a network.
