What is VoIP

Voice over IP (Internet Protocol) In short, VoIP means; speech over the Internet Protocol. Using VoIP, existing networks such as the Internet can be used to make telephone calls. In combination with a broadband subscription with a fixed rate, calls can be made much cheaper than with traditional telephone services.

VoIP uses the IP protocol to transport voice packets over an IP network. The Voice signal is segmented into frames and stored in voice packs. These voice packets are transported over IP and are compliant with the International Telecommunications Union-Telecomunications (ITU-T) standard H.323 . This is the specification for the transport of Multimedia (Voice, Data and Video) over a network. The functionality of a telephone exchange with VoIP is often provided by the SIP Protocol.

Besides the fact that calls can be made between two VoIP parties, there are now also options for calling traditional telephones via VoIP, and vice versa. It is possible to build a bridge between these two different systems. Due to the integration with traditional telephony, VoIP is increasingly becoming a suitable alternative for this.

Little Background on UNIX

In the late 1960s, a group of ambitious developers led by Dennis Ritchie and Ken Thompson were seeking to create an operating system for mini computers known as PDP-7. This was done in order imitate what they saw on mainframes which had many features including multitasking capabilities but not one that could be used interactively. They called their creation Unix after another name previously given out by AT&T, Multiplexed Information and Computing Service.

Different kind of files:

• Symbolic links – When a file is pointing to another one, it’s called symbolic link. They are also known as soft links because they contain text that points at the location of your target in digital space—a kind if “virtual Associative Path” for files.

• Special files – These files contain information about the devices we use every day. For example, there is a file for your printer and another that tells how to make an image on CD-ROMs!

• • Ordinary files – These files are the backbone of your computer. They contain all sorts of important information like images, videos or instructions for how to operate it properly! When you see them listed with ‘ls -l’ they will be prefixed by an hyphen symbol (–).

UNIX Summed up

Though UNIX is no longer the most popular system in use, it remains an important platform for powering high-end applications and other crucial pieces of enterprise technology. For decades this operating system helped power some very critical IT operations around the world – especially those that are mission related or require sensitive data accesses to function properly. However recently there has been a rise out Linux which many companies now rely on because its free & open source; meaning either way you go Turbo PC Fix has the experience and technicians to help you along the way.
