When sociologists say that it is difficult to predict all the results of social change, what are they referring to?

Semiconductor memory is used mainly for primary storage even with its high cost. In another hand, the magnetic tape is the cheap

vodomira [7]

<span>In general you want to use the cheapest storage medium who's speed is compatible with the function it needs to perform. For active storage that's handled while running programs, you need memory whose speed is closely matched to the processor speed. And that would be the rather expensive semiconductor memory which is close to ideal for the task. But semiconductor memory has the disadvantage of being expensive and it loses the values stored when power is lost. So slower, persistent storage is used such as SSD (Solid State Drives) and hard disks. That media is cheaper, but slower, but still fast enough to handle tasks such as loading programs and data into memory for execution, or storing data generated by programs to persistent storage. But as with all man made things, disasters happen. Computers break down, hard disks crash, floods and fires happen, etc., and as a result data is lost. So we make backups. Backups have to have a lot of storage and they have to be cheap. But they don't need rapid access, you can start at the beginning and read (or write) all the way to the end. And for that purpose, magnetic tape is ideal. Magnetic tape is actually quite fast when you're simply streaming a continuous stream of data without any need to randomly access any piece of that data. And it's cheap, so you're willing to make a back up copy of your system and store that backup off site so a single disaster won't destroy both the primary system and the backup.</span>

In 1-2 pages, identify a social networking technology and identify at least 10 security and/or privacy risks the technology has

algol13

Answer:

One of the biggest social media giants has faced many such security and privacy risks in the past 3 years. 10 are listed below:

1. No one can forget the New Zealand attack on the mosque, and it was telecast live via it. And that is certainly a security risk. And if someone is able to stream live, the AI is in question definitely as this cannot be telecast.

2. Can you forget the various US shooting cases in the past 5 years? And many out of them where telecast lives on it. Again the AI, and the authentication is in question.

3. Many evils have many times advertised itself through it, and that is a security risk. This put up the question on the Data Scientists of the company.

4. It's a huge data on it, and many users have been able to misuse it, and that is a security risk. This put up the question mark on the application of the Big Data.

5. Once, the UK parliament questioned it to sell the secret data, and that was a privacy risk.

6. An Engineer was caught negotiating to sell secret users data to a third party, and that is a privacy risk as well as a question on management technology, as its possible now to check these kind of frauds.

7. Its accounts have been hacked many times, as well as millions of user-profiles, were stolen. This is a security and privacy risk.

8. Its data is still not safe as evils have proved they can break the authentication. However, it has reacted well, and they look like being a safe destination now.

9. Once, someone from Russia was caught collecting a lot of data from it. That was a security and privacy risk. And surely if someone is uploading a lot of complicated and confidential data, must be checked through proper AI implementation.

10. In India too there have been claims that a lot of personal information during elections 2014 was sold. That was a security and data risk. And the data scientists were proved vulnerable again. Its quite sure hence, a lot of work has to be done in Data Science and Artificial intelligence still.

However, its owner is one of the finest souls on earth. He donated all his money when he was blessed with a child. Some out of his team cheated, and else some technology failure or the huge amount of data was the reason for the fault. However, other companies are also facing such problems. And hence, he cannot be blamed for this. And the company now definitely has recovered from the nightmare that they faced in the past 3 years.

The answer is self explanatory.
