What are the first and the last physical memory addressesaccessible using

Misha Larkins [42]

Answer

For First physical memory address,we add 00000 in segment values.

For Last physical memory address,we add 0FFFF in segment values.

NOTE-For addition of hexadecimal numbers ,you first have to convert it into binary then add them,after this convert back it in hexadecimal.

a)1000

For First physical memory address, we add 00000 in segment value

We add 0 at the least significant bit while calculating.

10000 +00000 = 10000 (from note)

For Last physical memory address,We add 0 at the least significant bit while calculating.

we add 0FFFF in segment value

10000 +0FFFF =1FFFF (from note)

b)0FFF

For First physical memory address,we add 00000 in segment value

We add 0 at the least significant bit while calculating.

0FFF0 +00000=0FFF0 (from note)

For Last physical memory address,We add 0 at the least significant bit while calculating.

we add 0FFFF in segment value

0FFF0 +0FFFF =1FFEF (from note)

c)0001

For First physical memory address,we add 00000 in segment value

We add 0 at the least significant bit while calculating.

00010 +00000=00010 (from note)

For Last physical memory address,We add 0 at the least significant bit while calculating.

we add 0FFFF in segment value

00010 +0FFFF =1000F (from note)

d) E000

For First physical memory address,we add 00000 in segment value

We add 0 at the least significant bit while calculating.

E0000 +00000=E0000 (from note)

For Last physical memory address,We add 0 at the least significant bit while calculating.

we add 0FFFF in segment value

E0000 +0FFFF =EFFFF (from note)

e) 1002

For First physical memory address,we add 00000 in segment value

We add 0 at the least significant bit while calculating.

10020 +00000=10020 (from note)

For Last physical memory address,We add 0 at the least significant bit while calculating.

we add 0FFFF in segment value

10020 +0FFFF =2001F (from note)

Write a program code which asks for 80 numbers between 100 and 1000 to be entered.

Firlakuza [10]

Answer:

If you are using Python,

```count = 0

for i in range(0, 79):

a = int(input("Input a number: "))

if 100 <= a <= 1000:

if a > 500:

count += 1

else:

print("Please input a number between 100 and 1000!")

i -= 1

print(count)```

Explanation:

count refers to the number of 500s and above,

the for loop is required for the program to loop 80 times,

a is the input collected,

the nested if is to check whether the number is above 500 and the if is used to check if the number is between 100 and 1000 if not, it will output that you need to input a number between 100 and 1000,

the i-=1 is required to make sure that part wasn't counted.

and the last print is to output the number of numbers above 500

Use the table on the right to convert from binary to decimal.

postnew [5]

Answer:

There is no table, so I can only comment on the statements:

The binary value of decimal 10 is A. ==> False, however A is a hexadecimal representation of 10.

The binary value of decimal 13 is 1001 ==> False, 13 would be 1101.

The binary value of decimal 15 is 1111. ==> True.

The binary value of decimal 14 is E. ==> Again E is a hexadecimal representation of 14.
