marshall27 [118]2 years ago
3 0

Answer:

Probably because it's really expensive and not well known.

Explanation:

Some metals and plastic are not able to be altered for 3D printing, which makes this harder for some people to get hold of. Most of the materials are also not able to be recycled, which makes it harder.

How many bits can a memory chip with the below configuration support? For full credit, show how you got the answer.
tatiyna

Answer:

Total Memory= 4 KB = 4096 bytes = 32768 bits

Explanation:

<em><u>1. Data lines are 8 From D0 to D7</u></em>

so

Total memory at single address locations is 8 bits.

<em><u>2. Address lines are 12 (A0 to A11)</u></em>

There are 12 address lines but 3 out 12 are for selction of chip or memory bank.

so only 9 pins are there to address the locations on one chip.

Total No. of address locations on single chip = 2^9 = 512 locations

as 1 location is 1 byte so total memory of single chip is 512 bytes.

<u><em>3. Total Memory Bank </em></u>

There are total 3 selection pins for memory bank.

so

Total chips = 2^3 = 8.

<em><u>4. Total Memory </u></em>

Total size of 1 chip = 512 bytes

Total size of 8 chip = 8x512 bytes = 4096 bytes = 4096/1024 kb = 4 kb

<em>So total memory of system is 4 Kb = 4096 bytes = 32768 bits</em>

write a function that returns a list, where each member of list contains previous day’s value multiplied by 2.​
sergeinik [125]

Answer:

Explanation:

The following code is written in Java, the function takes in a list with the previous day's values. The function then uses that list, loops through it and multiplies each individual value by 2 and returns the modified list. The first red  square represents the test case for the function, while the second red square in the image represents the output.

 public static ArrayList<Integer> doubleIt(ArrayList<Integer> mylist) {

       for (int x = 0; x<mylist.size(); x++) {

           mylist.set(x, mylist.get(x)*2);

       }

       return mylist;

   }

What's the difference between kilobyte and kibibyte, and why was the IEC convention for computer international memories made???
Masja [62]

Answer:

The Kibibyte was developed to take place of the kilobytes in the computer science context where the Kilobyte stands for 1024 bytes. And the Kilobyte interpretation to mean 1024 bytes, conflicts the Standard definition of the prefix kilo or 1000. And the IEC convention for computer international memories was made to define the international standards for electrical, electronic and related technologies.
