Answer: Middleware is a program that acts as the middle connection for a client and server .It helps the client and server to connect with each other for sending the request,  communication, etc. Middleware is designed in such a way that the functioning does not gets noticed by the client and server.

Example- Two-tier architecture of the client and server for database application can be the train ticket reservation. The reservation made by a people will be according to the time , the person who gets chance to access the reservation first will get the ticket while others wait in queue.

If any query regarding the reservation according to the database occurs then Java Database connectivity (JDBC) will act as the middleware for the Java data collection between the application(client section) and database (server).

let m be a positive integer with n bit binary representation an-1 an-2 ... a1a0 with an-1=1 what are the smallest and largest va
Ahat [919]

Answer:

Explanation:

From the given information:

a_{n-1} , a_{n-2}...a_o in binary is:

a_{n-1}\times 2^{n-1}  + a_{n-2}}\times 2^{n-2}+ ...+a_o

So, the largest number posses all a_{n-1} , a_{n-2}...a_o  nonzero, however, the smallest number has a_{n-2} , a_{n-3}...a_o all zero.

∴

The largest = 11111. . .1 in n times and the smallest = 1000. . .0 in n -1 times

i.e.

(11111111...1)_2 = ( 1 \times 2^{n-1} + 1\times 2^{n-2} + ... + 1 )_{10}

= \dfrac{1(2^n-1)}{2-1}

\mathbf{=2^n -1}

(1000...0)_2 = (1 \times 2^{n-1} + 0 \times 2^{n-2} + 0 \times 2^{n-3} + ... + 0)_{10}

\mathbf {= 2 ^{n-1}}

Hence, the smallest value is \mathbf{2^{n-1}} and the largest value is \mathbf{2^{n}-1}

7.3 A hydraulic lift has a mechanical advantage of 6. If the load weighs 780 N, calculate
Zielflug [23.3K]

Answer:

Effort = 120 Newton

Explanation:

Given the following data;

Mechanical advantage = 6

Load = 780 N

To find the effort required to lift the weight;

Mechanical advantage can be defined as the ratio of the load (weight) lifted by a simple machine to the effort (force) applied.

Mathematically, the mechanical advantage is given by the formula;

M.A = \frac {Load}{Effort}

Making effort the subject of formula;

Effort = \frac {Load}{M.A}

Substituting into the formula, we have;

Effort = \frac {720}{6}

Effort = 120 Newton.
