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 Scheme function called "sum" which takes an input function func and a nonnegative number n and outputs the value
solong [7]

Answer:

function sum(number) {

      if (number == 1) {

             return 1;

      }

      return number + sum(number -1);

}

Explanation:

This is a recursive function, it means that is a function that calls itself for example: if you call the function with sum(5) the process is :

sum(5)

   |______ 5 + sum(4)

                           |_______ 4 + sum(3)

                                                       |______ 3 + sum(2)

                                                                                   |_____2 + sum(1)

                                                                                                        |_____ 1

                                                                                                 

the result is 1+2+3+4+5 = 15

using a timer to generate a random number, develop a program that displays random numbers between 1 and 47 (or whatever) for you
mestny [16]

Answer:

Explanation:

The following code is written in Python. It creates a variable that detects the current time. Then it loops through a range of numbers and chooses the last random number after 2 seconds. Finally, it prints that number to the screen. This function can be called countless times depending on the number of state lottery numbers needed.

import random

import time

start_time = time.time()

while time.time() - start_time < 2:

   lottery_number = random.randint(0, 48)

print(lottery_number)
