Answer:

a) 8 bits b) 16 bits. c) 2¹⁶ * 24 bits d) 2²⁴ -1

Explanation:

a) In order to be able to accommodate 150 different instructions, the number of bits needed must be equal to the minimum power of 2 that satisfies this equation:

2n > 150, i.e. n=8.  

b) If the total number of bits for a word is 24, and 8 are used for the op code, there are 16 bits left for the address part.

c) If the address part has 16 bits, this means that the total addressable space is just 2¹⁶, so the maximum allowable size is 2¹⁶ * 24 bits.

d) As we have 24 bits to be filled, the largest unsigned binary number is just 2²⁴ – 1 .

(As we need to leave a position for all zeros).

tia_tia [17]

Answer:

M1 is equal to $ 4 trillion

Explanation:

M1 money supplies are liquid money supplies like cash, checkable deposits, traveler's check etc. It is equal to;

M1= coins and currency in circulation + checkable (demand) deposit + traveler's check.

M2 money supply are less liquid and is equated as;

M2 = M1 + savings deposit + money market fund + certificates of deposit + other time deposits.

Savings = $7 trillion

Checkable deposit = $3 trillion

Money market fund = $1 trillion

Currency = $1 trillion

Certificates of deposit = $1 trillion

M1 = currency + checkable deposit

= $1 + $ 3

= $4 trillion.

/*using the select statement, that selects column name from the table blog.posts */  

SELECT blog.posts.user_id, blog.posts.body, users.name/*column name user_id, body, name*/  

FROM blog.posts/* use table name blog.posts*/

RIGHT OUTER JOIN users ON blog.posts.user_id = users.id;/*use right join that connect table through user_id*/

Explanation:

In the structured query language, RIGHT JOIN  is used to recovers from both the right side of the table both numbers, although the left table has no sets. It also ensures that even if the 0 (null) documents are linked inside this left table, its entry will always return the outcome row, but still, the number of columns from its left table will be NULL.

In the above-given right join code, the select statements used that selects the column names "user_id, body, and the name" from the table "blog. posts" and use the right join syntax to connect the table through the id.
