RAID – CompTIA A+ 220-1101 – 3.3

We rely on our storage devices for access to our most important documents. In this video, you’ll learn how RAID can be used to maintain the uptime and availability of our data when a drive fails. << Previous Video: Storage Devices Next Video: Motherboard Form Factors (coming soon!) >>

Storage Devices – CompTIA A+ 220-1101 – 3.3

There are many ways to store and access files on our computing devices. In this video, you’ll learn about hard drives, solid state drives, flash memory, and optical drives. << Previous Video: Memory Technologies Next Video: RAID >>

Memory Technologies – CompTIA A+ 220-1101 – 3.2

Our system RAM can provide a number of different features. In this video, you’ll learn about virtual memory, multi-channel memory, parity memory, and error correcting code (ECC) memory. << Previous Video: An Overview of Memory Next Video: Storage Devices >>

Fiber Connectors – CompTIA A+ 220-1101 – 3.1

Many of our device connectors are made over copper cables. In this video, you’ll learn about RJ11, RJ45, USB, Lightning, and other copper connector types. << Previous Video: Copper Connectors Next Video: An Overview of Memory >>

Copper Connectors – CompTIA A+ 220-1101 – 3.1

Many of our device connectors are made over copper cables. In this video, you’ll learn about RJ11, RJ45, USB, Lightning, and other copper connector types. << Previous Video: Adapters and Converters Next Video: Fiber Connectors >>

Adapters and Converters – CompTIA A+ 220-1101 – 3.1

We don’t always have the right cable for the job. In this video, you’ll learn how adapters and converters can be used to switch between video and data connections on our desktop and mobile devices. << Previous Video: PATA Device Cables Next Video: Copper Connectors >>

PATA Device Cables – CompTIA A+ 220-1101 – 3.1

PATA is a common storage drive connection type on many legacy computers. In this video, you’ll learn about the PATA connector, storage drive connections, and the differences between a PATA and SATA data cables. << Previous Video: SCSI Device Cables Next Video: Adapters and Converters >>

SCSI Device Cables – CompTIA A+ 220-1101 – 3.1

SCSI has been an industry standard for decades. In this video, you’ll learn to recognize SCSI cables and the difference between SCSI connections over parallel and serial links. << Previous Video: SATA Device Cables Next Video: PATA Device Cables >>
