Basics of Computer Networking
Understanding TCP/IP Protocol
● Transmission Control Protocol (TCP)
● Internet Protocol (IP)
Importance of Internet Protocols
● Allow different devices and networks to communicate
● Provide structure and organization to data transmission
IP Addressing and Port Numbers
● Unique identifier for devices on a network
● Port numbers identify specific applications or services on a device
Web Browsing and HTTP Protocol
● Hypertext Transfer Protocol (HTTP) used for communication between web
servers and browsers
● HTTP Request and Response messages
Internet Speed and Bandwidth
● Speed measured in Megabits per second (Mbps)
● Bandwidth refers to the maximum amount of data that can be transferred at one
time
Structure of Network
● Physical and Logical components
● Network Topologies
Types of Networks
● Local Area Networks (LAN)
● Wide Area Networks (WAN)
● Wireless Networks (WN)
OSI Model Layers
● Seven layers that define how data is transmitted in a network
● Application, Presentation, Session, Transport, Data Link, and Physical layers
Transport Layer Protocol
● Transmission Control Protocol (TCP) and User Datagram Protocol (UDP)
● Provides reliable data transfer and error checking
Data Link Layer Basics
● Medium Access Control (MAC) addresses
● Framing and Physical addressing
Physical Layer and Hardware Components
● Network Interface Cards (NIC)
● Cabling and Connectors
HTTPS and Secure Communication
● Hypertext Transfer Protocol Secure (HTTPS)
● Encryption and Security
DNS and Domain Name System Explained
● Domain Name System (DNS)
● Translates domain names to IP addresses
Introduction to Network Fundamentals
● Network models and protocols
