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)

Can someone write a 5 sentence summary about Virtual Assistants. Please. I'm in a rush. Personal problems.

Lyrx [107]

Virtual Assistants can be useful. Blind people can use them to be informed, browse the web, and learn new facts. They can make tasks quicker too. They can control things like your heater or air conditioner. But if one were to malfunction, it could take lives.

VLD [36.1K]

Answer:

Cash cow

Explanation:

A cash cow is seen or made reference to as that part of a business, investment, or product that provides a steady income or profit.

Basically a cash cow is a business unit, product line, or investment that has a return on assets (ROA) greater than the market growth rate. This is expressed with an Idiom to mean that it produces "milk" that is profit long after the cost of the investment has been recouped.

The strategic business unit of this organization having high market share in its industry, but the growth rate of the industry is expected to be stagnant over the long run is simply yielding steady profit for the corporation through its high market value and this will continue for longer because it has to be at that high rate for a long period of time.

The SBU can be categorised as acting as the cash cow for that corporation.
