I don’t think that’s possible. giving control to edit records also means giving control to delete them. maybe discuss before hand to build trust and understanding or duplicate the records in case she does delete them

How long would it take a 8 bit computer to calculate π to the thousandth place?
allochka39001 [22]
The average speed of an 8 bit computer is 0.50 MIPS or million instructions per second. There are three  thousand instructions per digit of the number in <span>π, the thousandth place needs 4 x 3 = 12 thousand instructions. The time it takes to do this is 12000 / (0.5 x 1000) = 24 seconds.

More registers appear to be a good thing, in terms of reducing the total number of memory accesses a program might require. Give
gulaghasi [49]

Answer:

Following is given the answer step by step:

Explanation:

First of all we will write a program using MARIE that will support the statement: Sum = (A + B) - (C + D). All the necessary comments are given in front of each statement:

Load    A                   # variable A will be loaded

Add     B                  # B will be added to A

Store   Temp1         # A + B will be stored in Temp1

Load    C                  # C will be loaded in memory

Add     D                 # D will be added to C

Store   Temp2         # C + D will ge stored in Temp2

Load    Temp1         # Temp1 will be loaded in the memory

Subt     Temp2         # Temp2(A + B) get subtracted from Temp1(A - B)

Store    Sum             # (A + B) - (C + D) will get stored in Sum.

We can see from above program that memory is accessed 9 times. While if C + D get executed first than memory accesses will be reduced to 7.

Above same program could be written using an architecture of 4 registers:

  • R1
  • R2
  • R3
  • R4

The program is as follows:

Load   R1 , A     #A  will be loaded into R1

Load   R2 , B    # B will be loaded into R2

Add     R1 , R2    # R2 gets added to R1 and the result is stored in R1 (A + B)

Load   R3 , C      # C loaded into R3

Load   R4 , D     # D loaded into R4

Add    R3 , R4   # Value in R4 gets added into R3 and R3 becomes (C + D)

                          #no memory accesses required for this operation

Subt   R1 , R4     #R4 (C + D) gets subtracted from R1 (A + B)

                         #no memory accesses required for this operation

Store  Sum        # The recent value will be stored into Sum

Here memory is accessed 5 times in total.

Ket [755]

Answer:

A. 4 CPUs and 6 megabyte cache memory

B. 1.3157 x10^-9 nanoseconds

Explanation:

The Intel core i5 7500 is a seventh generation central processing unit with a 4 CPU core and a 6 megabyte cache memory. It executes task at a clock cycle of 5 clock cycle at a speed of 3.8 GHz.

The relationship between frequency and clock cycle is,

Clock cycle = 1 / ( frequent).

So, One clock cycle = 1 / 3.8 GHz

= 0.3 x10^-9

For five clock cycles = 5 x 0.3 x10^-9

= 1.3157 x10^-9 nanoseconds.
