You decide to add 3 new hard drives to your computer so that you can increase the amount of storage one it when you install them you find enough sata connections on the motherboard, but it is short 1 sata power connecter, what is the easiest way to add a sata power connecter to the system?
a. purchase a new power supply.
b. use a molex to sata power adapter.
c. use the molex connector.
d. you will not be able to add the sata hard drive.

b. Use a Molex to SATA power adapter.

Explanation:

SATA power connector is a 15 pin power connector that is used to connect many computer parts like hard drive, cd drive, SSD, etc.

Molex connector is an old connector that is used as a power connector instead of a SATA connector on the same devices.

But the SATA connector overcomes the Molex connectors as it is easy to use and easy to install and can widely be used in many peripherals.

But even now power supply of the computer contains the SATA power connector as well as some spare Molex connector, which can be used when required.  

There are many Molex to SATA connectors that are easy to use when there is a shortage of SATA power.

So, according to the scenario, the most appropriate answer is option b.

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
