An alien from planet Tao has descended onto Earth. The Internet is a massive network of networks, a networking infrastructure. It connects millions of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the Internet.
Explanation:
- A packet is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network.
- Network packets are small amounts of data passed over TCP/IP networks.
- Latency measures the time it takes between your actions and the response between your computer, the internet, and everything in between.
- An IP address is a label which is used to identify one or more devices on a computer network. It is comparable to a postal address.
- The Domain Name System (DNS) is vital to the Internet, providing a mechanism for resolving host names into Internet Protocol addresses. Insecure underlying protocols and lack of authentication and integrity checking of the information within the DNS threaten the proper functionality of the DNS.
- Transmission Control Protocol is a standard that defines how to establish and maintain a network conversation through which application programs can exchange data. TCP works with the Internet Protocol which defines how computers send packets of data to each other.
Since Joan wants to see what her presentation would look like in the eyes of her audience, it might be best for her to use the Slideshow view that is available at the bottom right side of her desktop view.
This option is a full-screen form of her Normal view in Microsoft PowerPoint. The Slideshow view is represented by the projector screen symbol next to the zoom in and out bar.
It is a programmer's responsibility to contribute to society and human well-being is true.
Explanation:
- It is a programmer's responsibility to contribute to society and human well-being is true.
- The Association for Computing Machinery (ACM) is known as the world's largest educational and scientific computing society.
- It has its own Code of Ethics and another set of ethical principles which were also approved by the IEEE as the known standards of teaching and practicing software engineering.
- Programmers contribute to develop computer systems which can reduce negative impression to the society.
- The negativity includes as threats to safety and health, which can be reduced and make everyday activities and work easier.
- software developers should reduce the risk of harming others due to the coding errors or the security issues which could impact human well-being.
Answer:
B. {1, 2, 2, 3, 3, 4, 5}
Explanation:
Given
The above code segment
Required
Determine which list does not work
The list that didn't work is 
Considering options (A) to (E), we notice that only list B has consecutive duplicate numbers i.e. 2,2 and 3,3
All other list do not have consecutive duplicate numbers
Option B can be represented as:
![nums[0] = 1](https://tex.z-dn.net/?f=nums%5B0%5D%20%3D%201)
![nums[1] = 2](https://tex.z-dn.net/?f=nums%5B1%5D%20%3D%202)
![nums[2] = 2](https://tex.z-dn.net/?f=nums%5B2%5D%20%3D%202)
![nums[3] = 3](https://tex.z-dn.net/?f=nums%5B3%5D%20%3D%203)
![nums[4] = 3](https://tex.z-dn.net/?f=nums%5B4%5D%20%3D%203)
![nums[5] = 4](https://tex.z-dn.net/?f=nums%5B5%5D%20%3D%204)
![nums[6] = 5](https://tex.z-dn.net/?f=nums%5B6%5D%20%3D%205)
if (nums.get(j).equals(nums.get(j + 1)))
The above if condition checks for duplicate numbers.
In (B), when the elements at index 1 and 2 (i.e. 2 and 2) are compared, one of the 2's is removed and the Arraylist becomes:
![nums[0] = 1](https://tex.z-dn.net/?f=nums%5B0%5D%20%3D%201)
![nums[1] = 2](https://tex.z-dn.net/?f=nums%5B1%5D%20%3D%202)
![nums[2] = 3](https://tex.z-dn.net/?f=nums%5B2%5D%20%3D%203)
![nums[3] = 3](https://tex.z-dn.net/?f=nums%5B3%5D%20%3D%203)
![nums[4] = 4](https://tex.z-dn.net/?f=nums%5B4%5D%20%3D%204)
![nums[5] = 5](https://tex.z-dn.net/?f=nums%5B5%5D%20%3D%205)
The next comparison is: index 3 and 4. Meaning that comparison of index 2 and 3 has been skipped.
<em>This is so because of the way the if statement is constructed.</em>
