Question

what is the term for voice information delivered in digital form as packets of data using internet protocol (ip) instead of the traditional circuit - switched lines of the public switched telephone network (pstn)?

• call center
• voice over ip (voip)
• unified communications (uc)
• presencing

which of the following accurately describes at least one difference between web 1.0 and web 2.0?

• web 1.0 largely relies on the use of crowdsourcing, whereas web 2.0 does not.
• web 2.0 involves a more closed approach to the internet, relying less on collaboration than does web 1.0.
• web 2.0 largely relies on the use of crowdsourcing, whereas web 1.0 does not.
• web 1.0 enabled users who were not necessarily technically - proficient to contribute to the development of the web.

Explanation:

First Question:

• "Call center" is a facility for handling calls, not related to digital voice over IP.
• "Voice over IP (VoIP)" is defined as transmitting voice data as IP packets instead of traditional PSTN lines.
• "Unified communications (UC)" integrates multiple communication methods, not specifically about voice over IP.
• "Presencing" relates to presence information in communication, not voice transmission over IP.

• Option 1: Web 1.0 was more static, Web 2.0 uses crowdsourcing (e.g., wikis, social media), so this is incorrect.
• Option 2: Web 2.0 is more open and collaborative, so this is incorrect.
• Option 3: Web 2.0 relies on crowdsourcing (user-generated content, collaborative projects), while Web 1.0 was mainly static content from providers, so this is correct.
• Option 4: Web 1.0 was for consuming content, Web 2.0 allowed non - technical users to contribute, so this is incorrect.

Answer:

B. Voice over IP (VoIP)
