Subtract (100000)2 from (111)2 using 1s and 2s complement method of subtraction

GenaCL600 [577]

Answer:

-11001

Explanation:

The following steps are performed in order to perform subtraction of the given binary numbers:

Step 1:

Find 2’s complement of the subtrahend. The subtrahend here is 100000

100000

First take 1's complement of 100000

1's complement is taken by inverting 100000

1's complement of 100000 = 011111

Now takes 2's complement by adding 1 to the result of 1's complement:

011111 + 1 = 100000

2's complement of 100000 = 100000

Step 2:

Add the 2's complement of the subtrahend to the minuend.

The number of bits in the minuend is less than that of subtrahend. Make the number of bits in the minuend equal to that of subtrahend by placing 0s in before minuend. So the minuend 111 becomes:

000111

Now add the 2's complement of 100000 to 000111

0 0 0 1 1 1

1 0 0 1 1 1

The result of the addition is :

1 0 0 1 1 1

Step 3:

Since there is no carry over the next step is to take 2's complement of the sum and place negative sign with the result as the result is negative.

sum = 1 0 0 1 1 1

2's complement of sum:

First take 1's complement of 1 0 0 1 1 1

1's complement is taken by inverting 1 0 0 1 1 1

1's complement of 1 0 0 1 1 1 = 0 1 1 0 0 0

Now takes 2's complement by adding 1 to the result of 1's complement:

0 1 1 0 0 0 + 1 = 0 1 1 0 0 1

Now place the minus sign with the result of 2's complement:

- 0 1 1 0 0 1

Hence the subtraction of two binary numbers (100000)₂ and (111)₂ is

(-011001)₂

This can also be written as:

(-11001)₂

Extended essay on globalization not less than 200

Serggg [28]

Answer:

First of all, people have been trading goods since civilization began. In the 1st century BC, there was the transportation of goods from China to Europe. The goods transportation took place along the Silk Road. The Silk Road route was very long in distance. This was a remarkable development in the history of Globalization. This is because, for the first time ever, goods were sold across continents.

Globalization kept on growing gradually since 1st BC. Another significant development took place in the 7th century AD. This was the time when the religion of Islam spread. Most noteworthy, Arab merchants led to a rapid expansion of international trade. By the 9th century, there was the domination of Muslim traders on international trade. Furthermore, the focus of trade at this time was spices.

True Global trade began in the Age of Discovery in the 15th century. The Eastern and Western continents were connected by European merchants. There was the discovery of America in this period. Consequently, global trade reached America from Europe.

From the 19th century, there was a domination of Great Britain all over the world. There was a rapid spread of international trade. The British developed powerful ships and trains. Consequently, the speed of transportation greatly increased. The rate of production of goods also significantly increased. Communication also got faster which was better for Global trade.

Finally, in 20th and 21st -Century Globalization took its ultimate form. Above all, the development of technology and the internet took place. This was a massive aid for Globalization. Hence, E-commerce plays a huge role in Globalization.
