cpu - Virtual core vs Physical core -


after running script below project

http://sourceforge.net/projects/sysinforeport

i following output, can explain difference between two. question seems basic :-) bit confused output

cpu report   total number of cpus: 1   total number of (virtual) cores: 12   cpu id 0   cpu model: intel(r) xeon(r) cpu e5-2620 0 @ 2.00ghz   cpu cores: 6

what total no of cpu's vs no of virtual core vs cpu cores mean? when check no of cpu's in virtual box shows 24.:-?

i see following explanation this:

you have server "intel(r) xeon(r) cpu e5-2620 0 @ 2.00ghz" cpu. processor has 6 physical cores. if hyper-threading enabled processor, getting 12 virtual cores. , have 1 cpu there. reason of why see 24 cpus @ virtual box interface unclear me. can improve answer on matter of virtual box.

useful links are:

hyper threading

how many cores have @ system

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
