advantages and disadvantages of memory mapped I/O?
Explanation:
Advantages : The advantage of memory mapped I/O is that all instructions and addressing modes can be used for I/O access. This makes programming easier. When Direct I/O is supported, many microprocessors provide limited instructions and addressing modes for I/O access.Dis Advantages : But there are also disadvantages: An I/O error on a memory-mapped file cannot be caught and dealt with by SQLite. Instead, the I/O error causes a signal which, if not caught by the application, results in a program crash.

Given int n, return an int[] that contains the numbers 0, 1, .. n-1, n, n-1, ... 1, 0. For example, if n = 5, then the array should be 0, 1, 2, 3, 4, 5, 4, 3, 2, 1, 0.
Make sure its in the coding language Processing, Java, or Javascript
Answer:
// Given int n, return an int[] that contains the numbers 0, 1, .. n-1, n, n-1, ... 1, 0.
// For example, if n = 5, then the array should be 0, 1, 2, 3, 4, 5, 4, 3, 2, 1, 0.
function mirrorArray(max) {
const firstHalf = []; // initalize the first half (without max)
let count = 0; // we're gonna count up from 0 to the max
while (count < max) { // whilst the count is less than the max provided
firstHalf.push(count); // add the value of count to the array firstHalf
count++; // increment count by 1
}
const secondHalf = firstHalf.slice().reverse();
// we first chane the .slice() method which has no arguments
// this means we can copy our array before reversing it.
// if we did firstHalf.reverse(), we'd end up changing what's inside firstHalf too.
// we don't want that!
return [...firstHalf, max, ...secondHalf];
// ... is the spread operator
// it is used to remove the square brackets [] from an array
// for example: ...[1, 2, 3] becomes 1, 2, 3
}
console.log(mirrorArray(5)); // here we're calling our function, and providing a max of 5
Explanation:
Everything that needs explaining should be in the comments I've put in the code! If you need more help, please ask!
I decided to use JavaScript because I think it reduces the amount of extra code needed to get my intentions across to the computer.
P.S.: I've also attached a screenshot of my IDE because it can be hard to read code if it's not colored in!
Don't worry about the array's items being displayed above each other, it is just what my IDE does.

How CPU evolved over time ?
Answer:
From 1971 to 1972 the era of the first generation came which brought microprocessors like INTEL 4004 Rockwell international PPS-4 INTEL 8008 etc. The second generation marked the development of 8-bit microprocessors from 1973 to 1978. Processors like INTEL 8085 Motorola 6800 and 6801 etc came into existence.
Clock speeds have also suffered due to extreme miniaturization. For the past 5 years, clock speeds on mainstream processors have been stuck at around 3.7 GHz – 4 GHz. Higher clock speeds mean more energy use and therefore more heat buildup. A higher core count also helps with the problem of stagnated clock speeds.
Intel 4004
The Intel 4004 is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. Sold for US$60, it was the first commercially produced microprocessor, and the first in a long line of Intel CPUs.
