High-speed memory that reduces the frequency of access by the cpu to conventional memory is called

Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 t

Lady_Fox [76]

Answer:

# create the file

filename = "Testfile.txt"

# for writing, we create the output file:

outPutfile = open(filename, "w")

# Writing numbers from 1-100

for item in range(1,101):

outPutfile.write((str)(item))

outPutfile.close()

# printing the contents to verify it worked correctly

infile = open(filename, "r") #note the "r" indicates the mode

fileContents = infile.read()

infile.close()

print(fileContents)

Explanation:

Define the working file fileName = TestFile
Create the output file for writting outPutfile = open(filename, "w")
Use a for loop to write numbers from 1-100 to the file outPutfile.write((str)(item))
Close the file outPutfile.close()
You may open the file read its content and print the contents to verify it worked correctly

A digital computer has a memory unit with 16 bits per word. The instruction set consists of 72 different operations. All instruc

OLga [1]

Answer:

a. 7 bits b. 9 bits c. 1 kB d. 2¹⁶ - 1

Explanation:

a. How many bits are needed for the opcode?

Since there are 72 different operations, we require the number of bits that would contain 72 different operations. So, 2ⁿ ≥ 72

72 = 64 + 8 = 2⁶ + 8

Since n must be an integer value, the closest value of n that would contain 72 different operations is n = 7. So, 2⁷ = 128

So, we require 7 bits for the opcode.

b. How many bits are left for the address part of the instruction?

bits left = bits per word - opcode bit = 16 - 7 = 9 bits

c. What is the maximum allowable size for memory?

Since there are going to be 2⁹ bits to addresses each word and 16 bits for each word, the maximum allowable size for memory is thus 2⁹ × 16 = 512 × 16 = 8192 bits.

We convert this to bytes

8192 bits × 1 byte/8 bits = 1024 bytes = 1 kB

d. What is the largest unsigned binary number that can be accommodated in one word of memory?

Since the number go from 0 to 2¹⁶, the largest unsigned binary number that can be accommodated in one word of memory is thus

2¹⁶ - 1
