Fundamentals of Computer Hardware

Explore the computer console and its main components—motherboard, mass storage, and power supply—and learn how peripherals connect and how CPU, RAM, and chipset power the system.

Understand how peripherals include input and output devices, whether integrated or external, such as keyboard, monitor, mouse, microphone, printer, speakers, scanners, webcams, network devices, and external storage.

Explore wired peripheral connections, USB 2.0 and 3.0, blue and black connectors, plus hubs, audio and network ports, and legacy ports.

Learn the proper procedure for opening a PC console, disconnecting power safely, identifying major components like power supply, motherboard, and drive cage, and cleaning dust to prevent overheating.

Explore the computer power supply and cooling system, from wattage considerations and connectors to fans, case cooling, and optional liquid cooling for high-performance builds.

Explore the motherboard as the computer's hub, detailing the CPU, firmware, chipset, memory slots, and expansion slots, plus the I/O panel, and how the DirectX diagnostic tool reveals system model.

Examine the drive cage in a typical pc case, detailing 5.25in and 3.5in slots, removable media via punch-out panels, and two cables per drive for power and data.

Close the case only after confirming all components and cables are reattached, then power on to observe the startup sequence and ensure Windows appears before safely resealing.

Explore how the CPU drives a computer, from cores and GHz speed to caches and sockets, and why upgrading processors often costs more than buying a new PC.

Learn how RAM and DRAM differ from ROM and flash memory, explore memory slot configurations and DIMMs or SIMMs, and follow practical steps to upgrade memory on a PC.

Explore expansion cards and expansion slots, review PCI and PCI Express standards, and walk through installing a card and its drivers in Windows 10.

Cover internal storage options, boot drive roles, SATA interfaces, and how to add or replace drives. Also review external storage, partitions, and safe removal practices.

Explore the graphics system's display adapter and monitor, comparing integrated and dedicated graphics. Learn about VRAM, shared memory, and common connectors like DVI and HDMI.

Explore monitor types, formats, and settings, including LCD and CRT, screen versus display, input and power controls, and how to adjust brightness, color temperature, and sleep mode.

Configure the PC's graphics system in Windows by adjusting display orientation, resolution, and color calibration in advanced display settings, previewing changes, and applying or reverting settings.

Explore how to add a second monitor to a PC or laptop, switch display modes with Windows P, and extend or duplicate desktops with proper resolutions.

Explore the computer keyboard as the main input device, covering USB interfaces, wireless options, keyboard layout, magnetic membranes vs mechanical switches, and basic customization.

Explore pointing devices from mice and trackballs to trackpads and digital styluses, and learn connections, battery needs, and Windows 10 mouse settings for customization.

Learn how touchscreen monitors turn displays into input devices with USB connections, multiple input points, and stylus support. Master touch techniques such as tap, drag, long press, and double tap.

Learn how audio input and output hardware, jacks, and configurations drive Windows sound settings, from onboard and external speakers to USB mics and SPDIF, including surround sound basics.

Explore inkjet and laser printers with features like scan, copy, fax, and duplex printing. Learn to install, connect via USB or network, set a default printer, and use print dialog.

Explore the fundamentals of computer networks, including network adapters and MAC addresses, wired and wireless topologies, gateways, switches, and basic Windows access to network resources.

Configure a gateway securely by logging into its web interface, setting admin credentials, enabling the firewall and dhcp, and securing the wifi network with a WPA two password.

View and access shared network resources such as storage and printers, and map drives while enabling file and printer sharing and managing credentials.

Learn how Bluetooth enables wireless connection to peripherals like keyboards, mice, printers, and headphones, and master pairing, scanning for devices, and unpairing via Windows settings.
