Internal Connection Devices Like external storage connections internal connection types vary from one motherboard, and computer type to another on today's modern computers. We're examining SATA (serial advanced technology attachment)and PATA (parallel advanced technology attachment). We begin with SATA by looking at its minimum and maximum transmission speeds in terms of gigabytes per section, how many device connections is employs, and what computing systems will use this connection. Then you'll learn about the PATA connection which is also referred to as an IDE connector and allows for 2 device connections. You'll learn what a SCSI cable is (pronounced scuzzy), the significances of its two connection types, and which allows for the great number of device connections, how to identify and match up cables to the device types they can correct to, which end of a cable with the twisted connection sits on the motherboard and why.
