Answer:
Software is a set of instructions, data or programs used to operate computers and execute specific tasks. Opposite of hardware, which describes the physical aspects of a computer, software is a generic term used to refer to applications, scripts and programs that run on a device. Software can be thought of as the variable part of a computer, and hardware the invariable part.
Software is often divided into categories. Application software refers to user-downloaded programs that fulfill a want or need. Examples of applications include office suites, database programs, web browsers, word processors, software development tools, image editors and communication platforms.

Answer:
C
Explanation:
Joe should backup all his data from his old mobile device to his PC and then import all the data to his new device via PC. This is the fastest way for transferring data than all the other options mentioned. Most of the time the devices with different OS cannot connect via Bluetooth so option B is not suitable here. If we talk about logging in to same email provider on the new device, it might work but it'll take a lot of time to transfer data to a new device since the data is been copied through internet. If Joe has a strong internet connection than it might be a suitable option for him but what if the connections breaks down in middle of transfer? Similarly NFC also uses internet connection, but that's not only the problem with NFC, like Bluetooth, NFC also works with similar OS devices. Apart from that NFC only transfers small payloads of data.
Answer:
Explanation:
The following code is written in Java and creates the recursive function to find the longest common substring as requested.
static int lengthOfLongestSubsequence(String X, String Y) {
int m = X.length();
int n = Y.length();
if (m == 0 || n == 0) {
return 0;
}
if (X.charAt(m - 1) == Y.charAt(n - 1)) {
return 1 + lengthOfLongestSubsequence(X, Y);
} else {
return Math.max(lengthOfLongestSubsequence(X, Y),
lengthOfLongestSubsequence(X, Y));
}
}
Answer:
Look up Charles Babbage. He built a machine that is viewed as the predecessor of the modern computer.
That would be an Ergonomic keyboard, due to the fact that it is laid out in such a way that doesn't harm your wrists
