Speed of sata 1 is 1.5 Gbps Speed of sata 2 is 3 Gbps
cable
There are two types of cd/dvd drive available. Sata and Pata. Sata uses a small sata cable whereas pata uses an older ribbon style IDE cable. Sata is the best of these two but not all computer support sata, in those cases ide will do. As far as brand goes there is not much difference but the Pioneer, LG and Liteon drives tend to be reliable.
Absolute bandwidth is the relative bandwidth of the signal (B) times the center frequency (f0). For example , by increasing the center frequency, the relative bandwidth is unchanged, but the absolute bandwidth is increased due to increasing the center frequency. I hope it is helpful :-)
if there is no sata (serial ATA) device connected, this could be a hard drive, or cd drive etc,
HUB
LAN Bandwidth is the bandwidth (Maximum speed) of the Local Area Network
1m for SATA I, 2m for SATA II
cat 3, freq and bandwidth 16MHz cat 5, freq and bandwidth 100MHz cat 6, freq and bandwidth 200MHz
The maximum bandwidth of fiber optic cable is typically around 100 terabits per second.
If you plug a SATA 3.0 drive into a SATA 1.5 port on your motherboard, the drive should be able to function at a 1.5Gb/s transfer rate. Some drives require a jumper setting, while others natively recognize their allocated bandwidth and adjust accordingly.
Theoretical maximum throughput: SATA II: 3Gb per second. SATA III: 6Gb per second. The maximum uncoded transfer rates are 2.4 Gb per second and 4.8Gb per second, respectively.
To determine the maximum gain a device can extract at that particular bandwidth
100ft
1.5 gb/s
means the m.2 will get all of the power that the two sata 5 and 6 would get. it also means that the pathway the sata drives use is the same as the m.2.
Router having maximum bandwidth in network. and in network fiberoptic cable having max bandwidth for data travaling
