Ultimate IT Networking Fundamentals Mastery Course

Explore how computers take input from devices like keyboards, process data in the CPU, and output results to monitors, with data stored and converted to binary.

Transistors powered the second generation computer. Engineers commissioned the full version in April 1955, giving the device the nickname transistor computer.

The fourth generation computer, launched in 1970, uses a microprocessor, now called a cpu, powered by vlsi technology that can add up to one million transistors.

Understand the processor, or cpu, as the brain of the computer, and learn to evaluate specs like speed, bit, fsb, cache memory, virtualization, and generation.

Identify the front side bus as the data path between RAM and the processor, and compare processor and RAM speeds in megahertz to determine the maximum FSB speed.

Learn how cpu generations are determined by transistor size, where smaller transistors save power, and identify your processor generation in Windows by right-clicking this PC and viewing system properties.

The motherboard, or mainboard, connects cpu, ram, disk, keyboard, and lan card to enable communication; client boards have single cpu socket, while server boards offer multiple sockets for 24/7 operation.

Compare hard disk drives with moving platters and a reader to solid-state drives built from memory chips with no moving parts, highlighting faster speeds, greater durability, and smaller size.

Understand wide area networks, a collection of local area networks over geographical distance, and see LANs, a Bangalore LAN, connected via WAN, with the internet as a network of networks.

Interconnect campus area networks by linking local area networks across nearby buildings, spanning two to five kilometers, forming campus or corporate networks that provide library and internet access.

Explore guided media, or wired media, where cables transmit signals via a physical link for high speed and security, with coaxial, utp, udp, and fiber optic cables.

See how a wireless access point connects end devices to a LAN via RF signals, enabling Wi-Fi connectivity without cables, with coverage up to 2000 meters.

Learn how a firewall enforces security rules to separate untrusted internet from the trusted LAN, and how DMZ placement enables safe external access to web servers.

discover how IP phones use voice over IP over an IP network, linking through routers in a local area network, replacing PSTN for calls and using UDP cables for connection.

The lecture explains that windows server supports both gui and cli installations, with options such as standard evaluation cli and desktop experience for a gui install.

Explore Windows Deployment Service, which enables remote deployment and installation of Windows on computers booting from the network. See how it saves time when deploying Windows to many PCs.

Explore the different ways to install the Windows Server operating system, including booting from a DVD, using a bootable USB drive, or installing from a Microsoft ISO file.

Learn how to download and install VMware Workstation for lab use, including accepting terms, completing installation, launching the app, and creating a virtual machine.

Create a virtual machine in VMware Workstation for lab use, install Windows Server 2022 later, and save the VM as server-01 with 100 GB disk and 2 GB RAM.

Explain unicast, broadcast, and multicast through practical examples: unicast is 1-to-1 from a computer to a printer, broadcast sends to all devices, and multicast targets a selected group.

Learn the difference between private and public IP addresses, how NAT translates private to public for internet access, and how ISP, IANA, and regional registries allocate globally unique addresses.

Explore how topology maps device connections and data flow, distinguishing physical topology, which shows physical connections, from logical topology, which defines how data moves between computers.

Identify how a logical topology governs data flow and internal device communication in Windows workgroup and domain models.

Define a domain as a logical network; show how DNS provides a domain name and, with AIDS, turns a server into a domain controller that governs the domain.

Verify whether the Windows Server 2022 virtual machine is in a workgroup by checking computer name settings: right-click this PC, open properties, advanced system settings, and view the server name.

Promote the server to a domain controller by creating a new forest, selecting forest and domain function levels, configuring DNS and the global catalog, then install and restart.
