If you’re adding on features to an existing motherboard, then you may be connecting to one of the available expansion slots. In this video, you’ll learn about PCI (Peripheral Component Interconnect) and PCIe (PCI Express) expansion slot technologies. << Previous: Motherboard Form Factors Next Video: Motherboard Connections >> If you were to look at a […]

When purchasing or building a computer, you have a many options for motherboard type and form factor. In this video, you’ll learn about the ATX motherboard standard, the micro-ATX standard, and the ITX motherboard form factors. << Previous: RAID Next Video: Motherboard Expansion Slots >> If you were to look around at the different computing

We can combine multiple drives together to optimize data throughput and provide redundancy. In this video, you’ll learn about the redundant array of independent disks (RAID), and an overview of RAID 0, RAID 1, RAID 5, RAID 6, and RAID 1+0. << Previous: Storage Devices Next Video: Motherboard Form Factors >> We rely on our

There are many different options available for long-term data storage. In this video, you’ll learn about hard drives, solid state drives, PCIe storage, NVME, serial attached SCSI, mSATA, M.2, flash memory, and optical drives. << Previous: Memory Technologies Next Video: RAID >> The memory in our system is volatile. That means when we power off

Memory technologies include features to identify errors, correct issues, and improve performance. In this video, you’ll learn about parity memory, ECC memory, and multi-channel RAM. << Previous: An Overview of Memory Next Video: Storage Devices >> The memory modules that we use inside of our computers can be different depending on what that system is

Memory is one of the most important components of any computer. In this video, you’ll learn about RAM, DIMMs, SO-DIMMs, SDRAM, and DDR3, DDR4, and DDR5 memory. << Previous: Fiber Connectors Next Video: Memory Technologies >> You often hear the term memory associated with computers. How much memory is in your computer? Is your computer

Optical fiber allows for high-speed communication over long distances. In this video, you’ll learn about fiber optic SC, ST, and LC connectors. << Previous: Copper Connectors Next Video: An Overview of Memory >> If you’re working with fiber optics, there are a number of standard interfaces you might find. One of these interface types is

Do you have the right cable for the job? In this video, you’ll learn about RJ11, RJ45, F-connectors, punchdown blocks, USB, USB-C, Molex, Lightning, and DB-9 connectors. << Previous: Adapters and Converters Next Video: Fiber Connectors >> We’ll start our conversation of copper connectors with one that is relatively common, an RJ11 connector. This is

We don’t always have exactly the right cable or connector, but we might have a handy adapter or converter. In this video, you’ll learn about converting or adapting DVI to HDMI, DVI, to VGA, USB to Ethernet, USB-C to USB-A, or using one of the many interfaces on a USB hub. << Previous: Storage Cables

Many of the storage devices in our modern computers rely on a cable for connectivity. In this video, you’ll learn about connecting drives with SATA and eSATA interfaces. << Previous: Video Cables Next Video: Adapters and Converters >> If you’re connecting a hard drive inside of a desktop computer, then you’re probably using a standard
