      Currently there are two types of Internet Protocol (IP) addresses in active use: IP version 4 (IPv4) and IP version 6 (IPv6). IPv4 was initially deployed on 1 January 1983 and is still the most commonly used version. IPv4 addresses are 32-bit numbers often expressed as 4 octets in "dotted decimal" notation (for example, 192.0.2.53). Deployment of the IPv6 protocol began in 1999. IPv6 addresses are 128-bit numbers and are conventionally expressed using hexadecimal strings (for example, 2001:0db8:582:ae33::29). source : http://www.iana.org/numbers/ thanks tecno for your useful comments :) keep it up(Y)
  • TCP Transmission Control Protocol UDP User Datagram Protocol
    • Islam TeCNo
       
      The Diffrance between TCP and UDP is that TCP check the packet that packets are sent correctly ... but UDP just send and don't check ....so UDP is faster than TCP but TCP check that data is sent correctly .... so UDP is used in applications like Video Streaming (You Tube) and Voice Streaming too

  • Jabber, an instant-messaging protocol
    • Islam TeCNo
       
      Great protcol .....also Called XMPP and this is the protocol used by Google Talk
    • Islam TeCNo
       
      port 5222 i think is it's default :D
  • Internet Relay Chat (IRC)
    • Islam TeCNo
       
      I think this is a very old chat protocol
  • ED2K, A peer-to-peer file sharing protocol
    • Islam TeCNo
       
      I think this is used by emule P2P program !! A Great P2P File Sharing program
  • FTP, File Transfer Protocol
    • Islam TeCNo
       
      use port 21 :D

LOL - Wikipedia, the free encyclopedia - 0 views

shared by Islam TeCNo on 25 Jun 09 - Cached
  • OL (also written with some or all letters lowercase) is an abbreviation for laughing out loud[1][2] or laugh out loud.[3] LOL is a common element of Internet slang used historically on Usenet, but now widespread in other forms of computer-mediated communication, and even face-to-face communication. It is one of many initialisms for expressing bodily reactions, in particular laughter, as text, including initialisms such as ROTFL[4][5][6][7] or ROFL [8] ("roll(ing) on the floor laughing"), a more emphatic expression of laughter, and BWL ("bursting with laughter"), above which there is "no greater compliment" according to technology columnist Larry Magid.[9] Other unrelated expansions include the now mostly historical "lots of luck" or "lots of love" used in letter-writing.[10

CodeProject: C# vs C/C++ Performance. Free source code and programming help - 0 views

  • is compiled twice. Once while the program is written and second when the program is executed at the user's site. The first compilation is done by your C# builder and the second by the .NET Framework on the user's machine. The reason why C# compiled applications could be faster is that, during the second compilation, the compiler knows the actual run-time environment and processor type and could generate instructions that targets a specific processor.
  • A well designed C# program is more than 90% as fast as an equivalent "well-designed" C++ program
  • The problem with "not-freeing" the memory at the right time is that the working set of the application increases which increases the number of "page faults"
  • ...1 more annotation...
  • That's a nice question. Except for writing time-critical blocks of code, prefer C#. Write all your algorithmic code in C++ (not VC++ .NET), compile it into a dll and call that using a Dll Interop through C#. This should balance the performance. This technique is not new or not invented by me or anyone. It's similar the old age C programming vs Assembly, where people on one camp fight assembly programming is faster and the other camp stating C is easier to develop and then people started using assembly embedded within a C program for time-critical applications using an asm block.

    "Qubes is a security-oriented, open-source operating system for personal computers. It uses virtualization to implement security by compartmentalization and supports both Linux and Windows virtual environments. Qubes 3.0 introduces the Hypervisor Abstraction Layer (HAL), which renders Qubes independent of its underlying virtualization system."
