In general, synchronous communication means you have to wait for the answer all the time. The programming logic is simpler, but the cost that you spend a lot of time waiting.
If the options are:
<span>a. The people communicating don't need to be online at the same time.
b. There is lag time in the communication.
c. The communication occurs in real time.
a is false, you do need to be online to receive the message
b is true, typically you continue only after an acknowledgement
c is true, you wait for acknowledgement that occurs in real time (not necessarily fast though)</span>
Yes Microsoft and Apple used the closed-source approach to better secure from malware and make to make their operating systems more user friendly.
The dual-layer-IP allows ipv4 and ipv6 at the network layer to access a single tcp/udp stack.
<h3>What is the dual IP layer?</h3>
The word dual-stack is a word that connote a full or total duplication of all stages in the protocol stack ranging from its applications to the network layer.
Note that the dual-layer-IP method often gives room for a computer to run IPv4 and IPv6 simultaneously at the network layer, and all of the IP stack can access a different TCP/UDP stack.
