BUHAY OPIS

Masarap mag aral lalo na kung malaki ang allowance kaya mas gusto ko pa ang maging estudyante habang buhay pero hindi naman pwede yun kasi kelangan mo pumunta sa panibagong baitang ng buhay mo.Sa paglipas ng panahon kelangan mo ng mag hanap ng trabaho para may sarili ka ng pang gastos sa mga gusto mong gawin gaya ng pag-inom,pag gimik gimik,kumain ng gusto mo pagkain sa paborito mong restawran o food chain, at higit sa lahat ay pang deyt(kung ikaw ay lalake).Ngayong may trabaho ka na at tiyak na malaki ang posibilidad na sa opisina ang bagsak mo,empre naka graduate ka na eh,panibagong tao ang makakasalamuha mo,panibagong paligid at panibagong PAG-IBIG(kung ikaw ay nabigo sa iyong kasintahan nung nasa kolehiyo ka pa lang).Marami ka ng mga kakilala sa opisina nyo ang iba ay maganda ang ugali at ang iba naman syempre hindi mo gustong samahan at pakisamahan,hindi maiiwasan ang pag hingi ng pabor sa iyo at hindi naman pwedeng hindi mo pagbigyan kasi nga nahihiya ka pero ang hirap naman sa iba na akala nila laging pwede yun pabor na hinihingi nila nag kapag hindi mo pinag bigyan sila pa ang galit sa iyo,at ang iba naman ay hindi marunong magpasalamat man lang bilang pa kunswelo.Hay buhay nga naman mahirap talagang makisama sa ibang tao.Ang sa akin lang naman sana naman ay maintindihan din nila na hindi sa lahat ng bagay ay mapag bibigyan ang gusto nila at hindi sa lahat ng oras ay maayos ang pakiramdam mo,buti na lang at iilan lang naman ang mga taong may ganoong ugali sa aming opis,kaya yun mga tao na yun ay d ko na pinag papansin at paki alam ko kung ano man ang gawin nila.Sana magustuhan nyo unang post ko dito hehehe…..

History of VoIP

Voice over IP began as the result of work done by some hobbyists in Israel in 1995 when only PC-to-PC communication was available. Later in 1995, Vocaltec, Inc. released Internet Phone Software. This software was designed to run on a home PC (486/33 MHz) with sound cards, speakers, microphone, and modem. The software compressed the voice signal, translated it into voice packets, and shipped it out over the Internet. The technology worked as long as both the caller and the receiver had the same equipment and software. Although the sound quality was nowhere near that of conventional equipment at the time, this effort represented the first IP phone.

                 

VoIP came into existence as a result of work done by a few hobbyists in Israel in the year 1995 when only PC-to-PC communication was in vogue. Later on during 1995, Vocaltec, Inc. released Internet Phone Software. This particular software was intended to run on a home PC (486/33 MHz) with:

 

• sound cards
• speakers
• microphone
• modem

The software was used to compress the voice signal, convert it into voice packets, and then finally to ship it out over the Internet. This particular technology worked as long as both the caller and the receiver had the same tools and software. However, the sound quality was not even close to that of the standard equipment in use at that point of time. This attempt can be termed as the first IP phone that came into existence.

Vocaltec – one of the true pioneers of VoIP – Internet Phone product

It had initial success with Internet Phone, and had a successful IPO in 1996 and was perhaps the first “true” VoIP software application.  It helped lay the groundwork to make VoIP mainstream and was the first VoIP product on the shelves of Compusa and other retail outlets.   

In the old days of VoIP there were full-duplex issues and soundcard full-duplex driver issues.  If you didn’t have the latest sound card driver, you’d get a half-duplex CB/walkie-talkie type experience.  The Internet hadn’t really taken off at that point in history.  You had to download the latest sound card driver to get full-duplex VoIP sound. 

In 1996 they released and officially invented the protocol and today they are leading providers of the latest VoIP solutions. The technology is still fairly new and history is being written right now. 

Historically, VoIP software focused mainly on the DSP (Digital Signal Processors), primarily due to the components’ high representation in the design of VoIP platforms. Not surprisingly, OEMs centered their design decisions on which DSP they intended to use, with the standard considerations of performance, size, and power dissipation following suit. 

The VoIP software vendors responded in kind by supplying the necessary codecs and data packaging components necessary to run on the DSP, however this bottom-up approach left manufacturers to fend for themselves with the most critical design elements, including system management, signaling, call control, gateway control, and control plane interface. Often, the integration of these disparate components was quite a difficult process, requiring the stitching together of algorithms and protocols from many different suppliers. Consequently, system efficiency was sub-optimal, and time to market was painfully slow.
