Answer:
There are no additional components that can be added to the IPv4 protocol to improve its utility
Explanation:
The IPv4 protocol was developed in 1983 and is still the most widely used version worldwide. It consists of a 32-bit binary number that is normally represented in decimal notation, with four digits separated by dots that take values between 0 and 255.
This system limits the IPv4 protocol to 4,000 million different addresses, a figure that in the eighties seemed sufficient but that in practice has been scarce due to the revolution of mobile devices and the impending development of the Internet of Things ( IoT) that will trigger the number of devices connected to the network.
So, there are no additional components that can be added to the IPv4 protocol to improve its utility, since the world is running out of IPv4 addresses and is being replaced by IPv6.
Hope this helps!
Answer:
B. False
Explanation:
A page-replacement policy can be defined as a set of algorithm that instructs the operating systems on what memory page is to be swapped, paged out or written to disk in order to allocate more memory as they're required by various active processes during virtual memory management.
Some of the algorithms or techniques used by the operating system for page-replacement policy are;
1. Last In First Out (LIFO).
2. First In First Out (FIFO).
3. Least Recently Used (LRU).
4. Least Frequently Used (LFU).
5. Optimal (OPT or MIN).
Hence, the page-replacement policy means that pages are placed to make more space and to minimize the total number of page that would be missing.
