Information systems security,refers to all the methods involved with assuring information integrity as well as keeping it confidential, and available.
It can also be defined as -
The detection and provisoon of solutions to security breaches.
Access controls, which prevents unauthorized system access.
Protection of information either in transit or in a storage area.

Look at the top right of your computer while having a chrome tab open. You will see a line, a box, and a x. Hover over each and you can see the names.
Answer:
A milestone is a significant progress point within your project. Milestones' main purpose is to set goals you have to achieve in order to succeed and complete your project
Explanation:
-Example 1-
You have to write a report for your project. This report contains introduction, problem background, results, and recommendations. The milestones for writing your report could be:
Milestone 1: introduction section is completed
Milestone 2: problem background section is completed
Milestone 3: results section is completed
Milestone 4: recommendations section is completed
-Example 2-
You have to design a webpage that allows the user to login, enters his/her name, and logout. The milestones in this case could be:
Milestone 1: login functionality is completed
Milestone 2: text field for typing the name is placed
Milestone 3: submit name button functionality is completed
Milestone 4: logout button functionality is completed
Milestone 5: all components of the webpage are fully integrated
You might think the goals in these examples can be set differently, and that is true. The definition of the milestones is in general subjective and it depends on how you design the steps you want to follow to complete your project. You might also want to add these milestones to a timeline so you have an estimated schedule of the development of your project.

Answer:
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.
Explanation:
We can calculate the channel capacity using Shannon's Capacity formula:
C = B + log₂ (1 + SNR)
Where C = Channel Capacity
B = Bandwidth of the Channel
SNR = Signal to Noise Ratio
We are given SNR in dB so we need to convert it into a ratio.
= 10log₁₀ (SNR)
10 = 10log₁₀ (SNR)
1 = log₁₀ (SNR)
SNR = 10¹
SNR = 10
So, using Shannon Channel Capacity formula:
C = 10 x 10⁶ log₂ (1 + 10)
C = 34.5 MHz
Total amount of time required to transmit a 1MB file:
1MB = 1 x 8 Mbytes = 8Mb
C = 34.5 MHz = 34.5 Mb/s
Time required = 8Mb/34.5Mb/s = 0.23 seconds
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.
