comment How are clock rate measured and what does it mean?
There is (at least in theory) a "master oscillator" in the CPU which provides the basic timing signals for running everything. The frequency of this "clock" is the clock frequency. A "cycle" is one "tick" of the clock -- electrically the signal starts at some point (maybe zero, maybe -3, who knows) and jumps up/down to another voltage, maybe goes past the start point in the other direction, then returns to the start point to do it all again.

comment How instructions run in parallel?
(And you have multi-threading and pipelining conflated. They are two different things.)

comment How instructions run in parallel?
Well, first off, calls to getchar and putchar will "stall" the pipeline -- the parallel operation occurs mainly between instructions within a single method.

comment Computer tends to freeze and shutdown
Probably you need to reseat the RAM, and maybe the CPU.

comment Windows Update doesn't work and consumes 100% of CPU
If you Google "svchost netsvcs" you will get a mountain of advertising interspersed with the occasional suggestion on how to approach this.

Change the display options to make the "command line" column visible and see what the command line is.

Install Process Explorer, click the process name column until you get the tree representation, then find the instance of svchost.exe that is looping. Examine that process's tree to find the actual module involved -- often this is not a Windows module but some other application.

comment It takes my computer a long time to establish connections with websites
I recently switched ISPs and one of the boxes in our house was behaving poorly. Poked around and discovered that at some point I had set the nameserver address for that box to something other than the ISP's default (which was being flaky off and on). Switched it back to default and things were much better. (Note that you override name servers on a connection basis, meaning that a wired connection may work and a WiFi connection fail, or vice-versa.)

comment How do i get 100% battery charge back with Samsung battery life extender?
Note that there are two kinds of "battery extenders". One kind "throttles" the system so that is consumes power at a lower rate. The other prevents the battery from fully charging. On my Sony Vista box the "throttle" function is more obvious and easier to find than the other function.

comment Squealing coming from laptop power supply?
If the noise has stopped I'd let it go until it recurs. (Though the power bricks are generally reasonably cheap. And, forewarned, you have the time to get an authentic one, vs a cheap knockoff that doesn't really meet specs.)

comment Is it dangerous to put desktop computers in a stack in a well ventilated room?
Yes. They might tumble over and injure someone.

comment Maximum reliable duration to leave laptop open?
Isn't your laptop set up to sleep when not busy?? And what harm (other than wasted energy) occurs if it keeps running all the time? I close mine when not in use for hours, but mainly to save the display (whose backlight fluorescent tubes have a limited lifetime -- newer units with LED backlights would be less of a concern). A bigger concern is the battery -- if your unit has it you should enable the "Battery Care" function to extend battery life.

comment Cannot format USB flash drive, everything claims it's write protected
How to fix this problem: 1) Remove flash drive from your computer. 2) Hold over round receptacle next to your desk. 3) Release. 4) Purchase new drive for $5 at your local Walmart.

comment Can a faulty battery cause my laptop to shutdown even on AC line? (battery installed AND plugged in together)
I had this happen with my Sony Vaio when it was fairly new -- the unit would click and shut down hard. After mucking about I discovered that the unit would run just fine if NOT plugged in to the AC, and eventually I determined that the battery was being overcharged (or at least the unit thought so). Running the unit a couple of hours on battery temporarily fixed it, and using the Sony-specific "battery saver" feature to not charge over 85% permanently fixed it. The charger circuitry can get confused, especially on a new unit that's used mostly plugged in.

comment Windows 7 compressing doesn't reduce space
Very likely most of that data is already compressed.
