Voice over Internet Protocol - Wikipedia, the free encyclopedia - 0 views

  • Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched network
  • Internet telephony refers to communications services—voice, facsimile, and/or voice-messaging applications—that are transported via the Internet, rather than the public switched telephone network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end.[1]

      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

  • Rich Internet applications (RIAs) are web applications that have some of the characteristics of desktop applications, typically delivered by way of a proprietary web browser plug-ins or independently via sandboxes or virtual machines[1]. Examples of RIA frameworks include Curl (programming language), Adobe Flash/Adobe Flex/AIR, Java/JavaFX[2], uniPaaS[3] and Microsoft Silverlight[4].

Difference Between File Transfer Protocol and Hyper Text Transfer Protocol - 0 views

  •  
    In this post under Computer Science Study Material for Gate, we are going to tell the differences between File Transfer Protocol (FTP) and Hypertext Transfer Protocol (HTTP). File Transfer Protocol FTP and HTTP both were developed to make Internet transmission better. FTP is used to exchange files between computer accounts, to transfer files between an account and a desktop computer (upload), or to access software archives on the Internet. It 's also commonly used to download programs and other files to your computer from other servers. It transfers files in two different formats ASCII for text files and Binary format for binary files.

What is Domain Name Resolution - 0 views

  • What is Domain Name Resolution Introduction When using the Internet most people connect to web sites, ftp servers or other Internet servers by connecting to a domain name, as in www.bleepingcomputer.com. Internet applications, though, do not communicate via domain names, but rather using IP addresses, such as 192.168.1.1. Therefore when you type a domain name in your program that you wish to connect to, your application must first convert it to an IP address that it will use to connect to. The way these hostnames are resolved to their mapped IP address is called Domain Name Resolution. On almost all operating systems whether they be Apple, Linux, Unix, Netware, or Windows the majority of resolutions from domain names to IP addresses are done through a procedure called DNS.

      i think it's great artical !!
    • Islam TeCNo
       
      Yes .....we know that Web sites are on servers that has IP adresses like this 217.143.56.12 for example .....this article tell us how the site name [www.google.com] is converted to the IP thanks Mans
    • magdy medhat
       
      ya tecno ya gamedddddd mesh de elly kona bntklm feha fel microbus :D
  • Hosts File - There is a file called the HOSTS file that you can use to convert domain names to IP addresses. Entries in the HOSTS file override any mappings that would be resolved via a DNS server
    • Islam TeCNo
       
      I think this is what some spam and adware programs use .... you type a normal site Name but you go yo another site ... i think so !!
  • Netbios - This only applies to Windows machines and will only be used to map names to IP addresses if all previous methods failed. This method will attempt to map the netbios name you are trying to connect to with an IP address.
    • Islam TeCNo
       
      any body can explain this point for me ?
  • ...2 more annotations...
  • This can be changed though by changing certain registry keys
    • Islam TeCNo
       
      start -> run -> regedit this will allow you to edit the registry
  • DnsPriority = 30 LocalPriority = 200 HostsPriority = 75 NetbtPriority = 100
    • Islam TeCNo
       
      Or Simpler DnsPriority = 1 HostsPriority = 2 NetbtPriority = 3 LocalPriority = 4

  • So bone up on JavaScript, CSS, and HTML to succeed over the next five years
  • Every top-flight developer I’ve met recommends learning at least one dynamic or functional programming language to learn new ways of thinking, and from personal experience, I can tell you that it works.
    • Abdelrahman Ogail
       
      yes, that's true (Y) some examples of these languages: LISP and Ruby. Prolog seems to be close to LISP becuase both were used in AI Applications

XML-RPC Home Page - 0 views

  • It's a spec and a set of implementations that allow software running on disparate operating systems, running in different environments to make procedure calls over the Internet. It's remote procedure calling using HTTP as the transport and XML as the encoding. XML-RPC is designed to be as simple as possible, while allowing complex data structures to be transmitted, processed and returned.

Uniform Resource Identifier - Wikipedia, the free encyclopedia - 0 views

shared by Islam TeCNo on 16 Jun 09 - Cached
  • In computing, a Uniform Resource Identifier (URI) consists of a string of characters used to identify or name a resource on the Internet. Such identification enables interaction with representations of the resource over a network (typically the World Wide Web) using specific protocols. Schemes specifying a specific syntax and associated protocols define each URI. Contents [hide]
    • Abdelrahman Ogail
       
      I've confused between URL & URI till reading this article !
    • Islam TeCNo
       
      URL no3 men el URI :D ....ana faker eno kont shoft el 7eta deh fe ketab 3an el HTTP bas nesetha .......Zanks Zikas Again
  • A Uniform Resource Name (URN) functions like a person's name, while a Uniform Resource Locator (URL) resembles that person's street address. The URN defines an item's identity, while the URL provides a method for finding it. The ISBN system for uniquely identifying books provides a typical example of the use of typical URNs. ISBN 0486275574 (urn:isbn:0-486-27557-4) cites unambiguously a specific edition of Shakespeare's play Romeo and Juliet. In order to gain access to this object and read the book, one would need its location: a URL address. A typical URL for this book on a unix-like operating system might look like the file path file:///home/username/RomeoAndJuliet.pdf, identifying the electronic book saved in a local hard disk. So URNs and URLs have complementary purposes.
