Introduction to Networking || Information Technology for Beginners || Chapter 04

Ever wondered how your computer talks to the internet? This video breaks down the fundamentals of networking in easy-to-understand terms! We cover everything from the basics of how devices connect and communicate, to essential network components, protocols, and architectures used in business IT.

What You'll Learn:

Networking Fundamentals:
Understanding what networking is and its fundamental role in IT systems.
Exploring the core components of a network: devices, media, and protocols.
Differentiating between Local Area Networks (LAN) and Wide Area Networks (WAN).

Network Architecture:
Learning about the Client-Server model and how it facilitates resource sharing.
Understanding how Network Interface Cards (NICs) enable device connectivity.
Exploring wired (Ethernet) and wireless (Wi-Fi) connection methods, including Access Points (APs).

Intermediary Network Devices:
Understanding the functions of Routers in connecting networks and directing traffic.
Learning how Switches enable efficient communication within a local network.
Exploring the role of Firewalls in network security and access control.

Network Addressing:
Understanding the purpose and structure of IP Addresses (IPv4 and IPv6).
Differentiating between Public and Private IP Addresses.
Exploring the function of MAC Addresses for local network identification.
Understanding the relationship between Private IPs and MAC Addresses.

Network Protocols:
Learning about the role of protocols in governing data transmission.
Exploring Network Layer protocols like IP and ICMP for routing.
Understanding Transport Layer protocols like TCP (reliable) and UDP (fast).
Examining common Application Layer protocols: HTTP/HTTPS (web), FTP (file transfer), SMTP/IMAP (email), SSH (secure access), and DNS (name resolution).

Data Transmission:
Understanding the concept of data packaging and the basics of the TCP/IP model (Application, Transport, Internet, Network Access Layers).
Exploring the processes of encapsulation and decapsulation.
