Where can I get more information about System programming in C?
Books or any websites
Where can I get more information about System programming in C?
Digital libraries like the ACM and the BCS Online library offer a great resource for specialised information with regards to Systems Programming and Computing related issues in general

Earthing arrangements query....Most common systems in UK:TN S;TN C S;Regardless of the system in all domestic?
The difference isZe or Zs values.The regs don’t allow use TNCS sys.in detached garage.Supply should be converted into TT.WHY?
IF U use drill in garage-fed from internal socket(RCD protected)through ext.lead - than this is OK. So why I have to create TT system in garage?
What if I have TNCS and want external socket, if is RCD protected–that comply? - Or I am not allowed to have it-Unless its part of TT system?
Imagine TNS system with damaged earth connection.U request upgrade of the earthing arrangements and They connect new earthing conductor into N is it? In all those systems the N is connected to E anyway
What if I will have high Ze value in TNS and connect my Main Earthing conductor to N at the service head–the Ze value should be lower?I think - in almost all cases when new supply is connected in London they provide PME supply regardless that your next door neighbor may have TNS system which is connected into the same underground supply conductor…..
What do you think?

Your garage is outside the "normal equipotential zone" therefor if you are supplying power to is as a separate fixed circuit then to guarantee an effective earth you should supply a means of earthing normally an earth rod(TT)You do not have access to the suppliers neutral terminal to connect your own earth to .If you have a socket that is protected by an rcd then it can be used outside no problem the rcd doesn't even have to be on that socket only it could be the main breaker
Reply:Ze is EFLI measured at the incomer,
Zs is EFLI measured at the accessory.
It's the supply company who do not permit you to export their earth. Nothing to do with wiring regulations. http://www2.theiet.org/Publish/WireRegs/...
Using an extension lead to supply a tool outdoors is not an installation by the very nature of it's temporary duration. Therefore also exempt from BS7671.
BS 7671 permits external sockets where RCD protected. On the house wall is still considered to be 'within the equipotential zone'
And while it's also up to the supplier to determine what earthing system you are give; the advantage of TNCS over TNS is that an earth doesn't have to be 'sweated' onto the lead sheath thus removing its (sweating) associated health and safety risks.
And you are breaking the law if you touch anything (Cut-out) owned by the supplier . It is THEIR property, not yours.
Reply:TT every time, that way you know there is a path to earth. It's not my profession so I am just expressing an opinion, but I always grew up working on the principle the shortest route to earth must be through a direct connection and not anything that goes via me or has any likelihood of doing so.
Top question though because I have never quite understood why PME is the preferred option nor why you would even want to rely on a armour sheath TNS to carry your earth back to the transformer via the neutral, which is live as soon as a phase is connected to it. It all gets to be a complex balancing exercise which is easily resolved by connecting the consumer end directly to earth as well.
I always guessed it was a cost cutting exercise to avoid additional cable runs for earth and saved the hassle of driving rods into gas mains etc. in towns
My system is generator and solar but I still have copper rods firmly driven in at all the connecting points.
I look forward to other answers.

Where can I find the start system by using C:/ on firefox?
I'm sorry, your question doesn't make any sense at all. C:/ has absolutely nothing to do with Firefox and visa-versa. Please use the box below questions to explain what you mean, or give us some idea as to what the problem is.
How do i do a system restore through c-drive?

How do i do a system restore through c-drive?
Just make sure that the box marked 'c' drive is checked.
Reply:go-to start....all programs...accesories....system tools then system restore..... if you go-to restore my system to an earlier time and have a look at the bold dates in the calendar these are the dates that you can go back to...if its a problem because of something installed it should be listed on the right as you go through the days....if you restore and everything is successful don't forget to switch off system restore by right clicking my computer and then properties and taking the tick out of the box....then switching it back on again by putting the tick back in the box as you don't want to have the same problem again.... good luck
Reply:go to control panel in start, then system restore, then select the options you want
away u go!!
