Hi. Why SAS is not on "the type of interfaces" list? Or is it something different?

[@computernetworkingnotesyoutube]

No, it is not different. It is a type of interface. Computer interfaces are very complex. You could study them for years and still have a lot to learn. So, I described them in the most simplistic terms possible. SAS is similar to SATA. Both use serial transmission to transfer data. Both use the following cable layout. two conductors for sending data two conductors for receiving data Ground cables in between the conductors to reduce interference In a SATA cable, all 4 wires are placed within the same cable. In a SAS cable, the 4 wires are separated into 2 different cables. SAS is generally more expensive, and it’s better suited for use in servers or processing-heavy computer workstations. SATA is less expensive, and it’s better suited for desktop file storage. Since SAS is similar to SATA and less used in personal computers, I explained SATA and skipped SAS to keep this video simple for beginners.

@@computernetworkingnotesyoutube Thank you for detailed answer. I'm newby and I want to become system administrator and get a job in data center someday. But such terms as: SAS / SATA / SCSI / PATA / NVME / PCI are SOOO STRESSFULL for me)) I don't understand absolutely nothing about it)) Maybe someday I will)) Thank you!))
