Explore legacy and modern video cables, including VGA, HDMI, TVI, and DisplayPort, then cover USB, Thunderbolt, and the evolution of USB generations and type C with adapters.

Explore various configurations for corporations, from graphic CAD workstations to virtualization and gaming rigs, highlighting RAM, solid-state drives, multiple monitors, and dedicated audio and video cards for editing and processing.

Explore enterprise domain concepts, Active Directory policies, and domain users, then demonstrate TPM-based encryption and Encrypting File System with RSA keys and certificate-based access.

Explore basic and dynamic disks, partition styles, and how primary, extended, and logical partitions with file systems support operating systems, boot data, and raid configurations.

Explore how the paging file boosts performance by temporarily storing less frequently used data, a Windows Millennium 2000 concept still used for certain processes.

Explore wireless and wired network configurations, from wifi direct and router-based connections to proxy settings, remote desktop options like Quick Assist, TeamViewer, and IoT device connectivity.

Master the Linux terminal foundations with core commands like ls, cd, mv, cp, rm, grep, and chmod for file management and permissions; learn IP basics, apt-get, vi, and symbolic links.

Explore laptop hardware components and how space constraints drive modular drives, integrated vs dedicated video cards, and key repair tasks. Learn about keyboards, touchpads, displays, power, batteries, and wireless connectivity.

Discover how the domain name system translates domain names to IP addresses, caches records, and routes queries through registrars, top-level domains, subdomains, and start-of-authority records.

Learn how dynamic host configuration protocol automatically assigns IP addresses and configures default gateway, DNS, and subnet mask, and how the four-step process (discover, offer, request, acknowledgement) manages leases.

Explore how SNMP exchanges management information between network devices via an SNMP manager, agents, and the management information base (MIB), enabling centralized real-time monitoring, alerts, and logs.

Learn how LDAP and directory services enable data discovery and authentication in domain environments, with a focus on port 389, Kerberos, HTTPS, SMB, and remote desktop protocols.

Discover how bluetooth creates a personal area network by linking devices via inquiry, pairing, and connection. Review profiles like sbp, hid, and a2dp, and note bluetooth 5’s IoT focus.

Configure VLANs on switches to create logical separation, assign ports to specific VLANs, and use trunk links to extend VLANs across switches, with access ports for hosts.

Learn Windows Server basics for security, covering Active Directory, Group Policy management and objects, domain and forest concepts, and password policies in hybrid Azure joined setups.

Explore wireless authentication evolution from wep to wpa2, compare tkip and aes encryption, and examine enterprise vs psk modes with radius and tacacs+ authentication servers.

Explore attack types including denial of service and distributed denial of service, botnet, zero day vulnerabilities, man in the middle, spoofing, brute force, dictionary, rainbow table, and noncompliant systems.

Explore operating system security through user permissions and account types: administrator, power user, standard, and guest. Understand NTFS and share permissions, inheritance, and administrative shares to control access.

Enforce security best practices across environments with complex passwords and expiration, plus screen lock and login restrictions. Manage accounts with guest and lockout policies, data encryption, and careful patching.

Learn to build a knowledge base and incident documentation, enforce regulatory compliance and acceptable use policies, and manage change requests with risk analysis, approvals, backups, and inventory controls.

Explore remote access technologies and security, noting telnet's insecurity, the use of encrypted connections and SSH in Linux/Unix, and RDP for cloud or network access with proper sign-out.

Discover cloud computing, its types and services from infrastructure as a service to platform as a service to software as a service, enabled by virtualization.
