What happens when the computer is thrashing? quizzlet?

When computers need to use more memory than have RAM, they'll swap out pages of memory to their drive. When they need those memory pages, they'll swap out others and swap in the needed ones. If a computer needs enough additionall memory, it can get so busy swapping that it doesn't have any (or very little) time to do any useful work. That is called thrashing.

Unix calls swapping swapping. Windows calls it paging, probably because of the memory pages. Memory pages are 4096 (4KB) sections of memory.

Unix drives are usually partitioned with a swap partition, and swap files can be made in the filesystem. Windows just has pagefiles[s].

Why are duplicate tuples not allowed in a relation?
velikii [3]

Answer:

Explanation:

Duplicate tuples are not allowed in a relation because the specifications of the constraints of the regional integrity are violated, especially the main constraint that states that there can be no identical values for the attributes of two tuples at any database relation state.

Also, duplicate tuples are not allowed in a relation due to the fact that they lead to redundancy of the data base which in turn, slowing down the speed of the database when data processing such as inserting, querying, updating, deleting, etc are being performed.

1. Write a high level algorithm for cooking a cheeseburger.
pishuonlain [190]

Answer:

1.  A high level algorithm for cooking a cheeseburger could be:

  1. Heat fry pan
  2. Cook one side of the hamburger
  3. Wait
  4. Turn hamburger upside down
  5. Put cheese over hamburger
  6. Wait
  7. Cut hamburger bread in half
  8. Put cooked hamburger inside bread
  9. End (eat)

2. A detailed algorithm for cooking a cheeseburger could be:

  1. Place fry pan over the stove heater
  2. Turn on heater (max temp)
  3. IF fry pan not hot: wait, else continue
  4. Place raw hamburger on fry pan
  5. IF hamburger not half cooked: Wait X time then go to line 5, else continue
  6. Turn hamburger upside down
  7. Put N slices of cheese over hamburger
  8. IF hamburger not fully cooked: Wait X time then go to line 8, else continue
  9. Turn off heater
  10. Cut hamburger bread in half horizontally
  11. Put cooked hamburger on one of the bread halves.
  12. Put second bread half on top of hamburger
  13. End (eat)

Explanation:

An algorithm is simply a list of steps to perform a defined action.

On 1, we described the most relevant steps to cook a simple cheeseburger.

Then on point 2, the same steps were taken and expanded with more detailed steps and conditions required to continue executing the following steps.

In computational terms, we used pseudo-code for the algorithm, since this is a list of actions not specific to any programming language.

Also we can say this is a structured programming example due to the sequential nature of the cooking process.
