Homework Help: Questions and Answers: What capability do smartphones have that telephones with earlier technology lacked?
A. Wireless technology
B. Data services
C. Mobility
D. Voice transmissions
Answer:
First, let’s understand what traditional telephones (landlines) could do:
- Make voice calls
- Some had cordless handsets for limited mobility within the home
- Later models could transmit data (fax, dial-up internet)
Given Options: Step by Step Answering
a) Wireless technology
- Telephones with earlier technology were typically wired, and smartphones have the capability to connect wirelessly (e.g., Wi-Fi, Bluetooth, cellular networks). This is a valid point.
- However, certain cordless telephones also had wireless features before smartphones, so while true, this is not the most distinct feature exclusive to smartphones.
b) Data services
- Smartphones can access the internet, run apps, and transmit data (like emails, social media, etc.), which earlier telephones could not do.
- Data services are a significant capability that older phones did not have. This is likely the best answer because it points out a feature specific to smartphones.
c) Mobility
- While smartphones are highly mobile, even earlier mobile phones provided mobility, such as basic cell phones. Mobility was already present in telephones before smartphones, so this isn’t unique to smartphones.
d) Voice transmissions
- Both smartphones and older telephones can transmit voice. This is a feature that telephones have had since the beginning. Thus, this is not a differentiating factor.
Final Answer
Based on the above analysis, the capability that smartphones have that earlier telephones lacked is comprehensive data services is:
b) Data services.
