Answer:
The answer is A. True.
Explanation:
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.

Answer:
t= 8.7*10⁻⁴ sec.
Explanation:
If the signal were able to traverse this distance at an infinite speed, the propagation delay would be zero.
As this is not possible, (the maximum speed of interactions in the universe is equal to the speed of light), there will be a finite propagation delay.
Assuming that the signal propagates at a constant speed, which is equal to 2.3*10⁸ m/s (due to the characteristics of the cable, it is not the same as if it were propagating in vaccum, at 3.0*10⁸ m/s), the time taken to the signal to traverse the 200 km, which is equal to the propagation delay, can be found applying the average velocity definition:

If we choose x₀ = 0 and t₀ =0, and replace v= 2.3*10⁸ m/s, and xf=2*10⁵ m, we can solve for t:

⇒ t = 8.7*10⁻⁴ sec.
<u>The most important job duty of a software developer is to develop a product/program that is easy to use and melts a customer’s need.</u>
<u></u>
Explanation:
Some other duties of a Software developer are
- Researching,designing and implementing new software program's and then managing them
- Testing and evaluating the developed software program's
- Identifying errors in the existing program's and modifying the same
- Writing effective codes
- employing various software tools
- Training new users
- Working closely with the other developers
Doubly linked chain
When a linked chain contains nodes that reference both the next node and the previous node, it is called a doubly linked chain. This type of chain is often used in data structures because it provides a way to easily traverse the data in both directions. However, because each node must reference both the next node and the previous node, doubly linked chains require more memory than singly linked chains.
