Calculate how much disk space (in sectors, tracks, and surfaces) will be required to
store 300,000 120-byte logical records if the disk is fixed sector with 512 bytes/
sector, with 96 sectors/track, 110 tracks per surface, and 8 usable surfaces. Ignore
any file header record(s) and track indexes, and assume that records cannot span
two sectors.

The amount of disk space in sectors that would be required to store 300,000 records is equal to 75,000 sectors.
Given the following data:
Number of records = 300,000.Size of each logical record = 120 byte.Number of bytes (sector) = 512.Number of sectors per track = 96.Number of tracks per surface = 110.How to calculate the required disk space?First of all, we would determine the number of logical records that can be held by each sector as follows:
Number of logical records per sector = 512/120
Number of logical records per sector = 4.3 ≈ 4.0.
Now, we can calculate the required disk space to store 300,000 records:
Disk space = 300,000/4
Disk space = 75,000 sectors.
For the tracks, we have:
Disk space in tracks = 75,000/96
Disk space in tracks = 781.25 ≈ 782.
Disk space in tracks = 782 tracks.
For the surfaces, we have:
Disk space in surfaces = 782/110
Disk space in surfaces = 7.10 ≈ 8.
Disk space in surfaces = 8 surfaces.

Answers
Answer:
Explanation:
There are all sorts of possibilities for, say, inserting new technologies into existing processes. But most of these improvements are incremental. They are worth doing; in fact, they may be necessary for survival. No self-respecting airline, for instance, could do without an application that lets you download your boarding pass to your mobile telephone. It saves paper, can't get lost and customers want it.
But while it's essential to offer applications like the electronic boarding pass, those will not distinguish a company. Electronic boarding passes have already been replicated by nearly every airline. In fact, we've already forgotten who was first.

The statement that is false is: The boot process is the process for powering off a computer, which is the second option. The boot process is actually the process of starting or powering on a computer, not powering it off.
The boot process refers to the sequence of events that occur when a computer is powered on or restarted. It is the process of starting up the computer's hardware and loading the operating system into memory so that it is ready for use. During the boot process, the computer's firmware (such as the BIOS or UEFI) performs a series of checks and tests to ensure that the hardware components are functioning correctly. It then searches for the operating system on connected storage devices, such as the hard drive or solid-state drive, and loads it into memory.

I have a variable and set it equal to 5. 1 then send it as an argument to a function that adds 5 to the variable passed in. Outside the function print the variable (after the function executes).
What will it print?
A. 5+1
B. 4
C. 6
D. 5
Answers
Answer:
D. 5
Explanation:
If the variables original value was 5 then the value that will be printed is 5. This is because the variable is being passed as a parameter into the function and 5 is being added to the parameter value, not the actual global variable outside. Therefore, in order for the adjusted value to be printed then that new value that is returned by the function needs to be saved in a new variable. This can be seen in the example code below.

In the right situations, the use of multi-threads can allow for application speedup. Provide a small code example that illustrates how threads can be used to arrive at an appropriate result. Identify if there is a point where too many threads might impact performance of the application. g
Answers
Answer:
Explanation:
Threads allow an applications to run faster because they allow various tasks to run at the same time instead of doing one at a time and having to wait for one to finish before starting the next task. However, if too many threads are running at the same time, or a thread has a very large task or requires another task to finish before finishing its own then this can drastically impact performance. Mainly because too many resources are being used at a single moment. The following code is a small example of how threads work in Python.
import threading
import time
def thread_function(name):
print("Thread {name}: starting")
time.sleep(2)
print("Thread {name}: finishing")
thread1 = threading.Thread(target=thread_function, args=(1,))
thread1.start()
time.sleep(1)
thread2 = threading.Thread(target=thread_function, args=(2,))
thread2.start()
