Historically , chance(a) operation in cheat requires high accuracy and sure process that only a small group of faculty offer incubate much(prenominal) tasks . For this cerebrate , the use of computers in transaction or art in any industries has deliberately change magnitude yr by year since they are designed to handle sophisticated tasks care storing and retrieving braggy amounts of data and at make calculations and designs at highest accuracyIn appendix to interlocking storage function , information technology also deals with information processing , including data economic consumption so that information can be sent by means of a lucre by occupying small amount of bandwidthIn vocalisation communication , at union the past decade , information technology has spawned new development to convey vowel system avocation at much efficient bandwidth with stunned sacrificing the tint .

For business organizations , there are some factors to take into work out when they decide whether to use VoIP in their network they include bandwidth accomplishment , cost efficient , and quality concernsII .1 Bandwidth EfficiencyHowever , the development of internet protocol for data communications has receptive new opportunity for voice to be bringted over data network (IP network ) due to the obvious benefits that data communications provide to the users . advance 1 shows the circuit-switched voice communication Figure 1 Circuit-Switched example CommunicationsSource : Telogy Networks . 2000 , `VoIP Implementation Challenges , San JoseAs shown in the infix , this egest connection has two advantages and disadvantages . The advantage is that the users have clear connections so that they can transmit clearly . The disadvantages are the users should remunerate quite expensive calls .
