Mhz Motherboard
I’m thinking of upgrading my motherboard(1.3 mhz) to a one. Any suggestions?
Well, it’s time to finally upgrade my slow-azz 1.3 mhz motherboard to a faster one. Does anyone have any good suggestions, comments, tips before I blindly pick and have one installed? Anything I need to watch for? Anything I need to know before I do it? The good products? FYI: I’m doing this mostly to help with my online gaming. =)
First thing is that it’s not the motherboard that’s the problem, it’s the CPU. That would be the rather large (usually about 1-1/2 to 2 inches square) chip hidden under a fan on the motherboard. The motherboard is the large green “board” that everything connects to.
OK, so in order to upgrade your CPU you need to find out what chipsets your motherboard supports. When you boot you will see a string of numbers at the bottom left of your screen – best the push the PAUSE button when they appear because they are gone in a flash – to resume boot just press any key – write these numbers down because they are your mother board and bios numbers – preceding these numbers there should be (from memory) something like “VIA” or “ASUS” which is the manufacturer of your motherboard.
Once you know what kind of motherboard you have, go to the manufacturers website and find out what chipsets it supports. That’ll tell you just how fast of a processor (CPU) you can get.
I’m guessing that since your current CPU is 1.3 (probably Ghz since 1.3 Mhz hasn’t been around since Jesus was here)
that you may need to upgrade your motherboard as well in order to get any of the higher-end chips.
Flash Memory
What is the difference between Flash memory and a hard drive?
what is the difference between the two? and do they use flash memory instead of hard drives in some computers and if not why?
Hard drives are electromechanical devices, flash memory cards are not. The fastest hard drive interface is sas, sata is the slowest. There are several performance levels to flash cards as well, different read/write speeds.

A college baseball team raises money by sellling baseball caps. The cost of making the caps includes a fixed cost of $500, plus $7 per cap. The caps sell for $15 each. What is the minumum number of caps the team can order in one batch and still raise money?
Number of caps produced: x
Fixed cost: 500
Variable cost: 7x
Total expense: 500 + 7x
Income: 15x
For the team to raise money, income > expense:
15x > 500 + 7x
8x > 500
x > 62.5
The minimum number of caps the team can order and still raise money is 63 (the smallest integer greater than 62.5).
Pin Serial
What is the maximum amprage for a serial 9-pin connectors (16550-compatible)?
The normal maximum for a 9 pin ‘D’ type sub miniature connector is 1 amp per contact, however the typical serial I/O chip is only designed to deliver 50mA per output pin.
The Maximum out voltage for RS232c is + 12v & -12v, although normally there is a ‘dead’ area between +3v ab -3v to absorb noise on the lines, some higher quality devices will work with a dead area as low as +1v & -1v.
