PLZ help with the following:
What is a reasonable wattage capacity for a power supply to be used with a system that contains a DVD drive, three hard drives, and a high-end video card?
Your boss assigns you a trouble ticket that says a computer is randomly shutting off after about 15 minutes of use. You have a theory that the computer is overheating. What utility program can you use to read system temperatures?
A 32-bit computer has two selector channels and one multiplexor channel. Each selector channel supports two magnetic disks and two magnetic tape units. The multiplexor channel has two line printers, two card readers, and five VDT terminals connected to it. Assume the following transfer rates.
Disk drive 700 Kbytes/s
The magnetic tape drive 200 Kbytes
Line printer 6.6 Kbytes/s
Card Reader 1.2 Kbytes/s
VDT 1 Kbytes/s
Estimate the maximum aggregate I/O transfer rate in this system.
The first ATX power supplies and
motherboards used a single
O 20-pin P1 connector
O 6-pin and 8-pin PCle connectors
O 24-pin P1 connector
The current trend is for the
motherboard to provide the video
components and video port, thus
increasing the overall wattage needs
