If a disk drive has 8 surfaces and there are 1024 tracks per surface with 256 sectors per track and 512 bytes/sector. What is th
1 answer:
Answer:
The capacity of the drive in Gigabytes equals 1.0737 Gbs
Explanation:
Given there are 1024 tracks per surface.
Number of surfaces = 8
Hence number of tracks in 8 surfaces equals tracks
Now it is given that there are 256 sectors per track thus the number of sectors in 8192 tracks equals sectors
Now it is given that there are 512 bytes per sector thus the number of bytes in 2097152 equals bytes
Converting to gigabytes the capacity of the drive in gigabytes equals 1.0737Gbs

Answer:
function countEvens(list) {
// IMPLEMENT THIS FUNCTION!
var even = [];
for(var i = 0; i < list.length; i++){
if (list[i] % 2 == 0){
even.push(list[i]);
}
}
return console.log(even)
}
var list = [ 17, 8, 9, 5, 20 ];
var count = countEvens(list);
Explanation:
The programming language used is JavaScript.
An even variable is initialized, to hold the even variables within list.
A FOR loop loop iterates through all the elements in the list, an IF statement is used to check using the modulo division to check if the elements in the list are even.
The even elements are appended to the even list using .push() method.
Finally, the function returns the even list and outputs the list to the log using console.log(even) .
A list is created and the function is called.
