Answer:

The following are the answer to the given points:

Explanation:

In point (a):

Calculating the long-distance call cost:

$= 4 \times 5 \times 0.40 \\= 20 \times 0.40\\= 8$

Calculating the local call cost:

$= 10 \times 3 \times 0.05\\ = 30 \times 0.05\\= 1.5$

Calculating the overall cost of PSTN:

$= 25 + (4 \times 5 \times 0.40) + (10 \times 3 \times 0.05) + 2000 + 275 \\= 25 + 8 + 1.5 + 2000 + 275 \\= 2309.5$

In point (b):

Calculating the call rate per second and the average arrival rate:

$\to (\lambda) = 0.2$

The call average length:

$\to (T_s) = - 8 \\\\ = (8 \times 60) \ seconds \\\\ = 480 \ seconds$

The complete agent number:

$\to (m) = 9$

The strength of traffic:

$\to u = \lambda \times T_s \\\\ = (0.2 \times 480) \\\\ = 96$

The occupancy of the agent:

$\to p = \frac{u}{m} \\\\$

$= \frac{96}{9} \\ \\= 10.66$

Calculation of obtained:

$= \frac{(\frac{um}{m!})}{(\frac{um}{m!})} + (1-p) \sum {m-1} _{k=0} \ \frac{uk}{k!}$

We get = 0.329 to substitute values.

In point (c):

The rate of blocking = $5 \%$

average call time $(T_s) = 480 \ seconds$

$= 0.05 \times 480 \ seconds \\ = 24 \ second$

In point (d):

Calculating the number of link, which is required:

$= \frac{275}{5} \\\\ =55$

In point (e):

Calculating the Line Number:

$= \frac{275}{5} \\\\ =55$

PSTN line number:

$= (\frac{2000}{55}) \\\\ = 36.3636\\\\= 37$

In point (f):

The gross design expense = $ 2309. 5

Define the following term. data, database, DBMS, database system, data- base catalog, program-data independence, user wen', DBA,

wolverine [178]

Answer:

data - Any form of value in a column of a table in a relational database.

DBMS - Short for Database management system, which is a software that can be used to create, manipulate and view databases, e.g. MS SQL Server.

database system - Same as DBMS.

database catalog - Place where the metadata of a Database, its tables, users etc. exists e.g. date created, size, number of columns etc. Also known as Data Dictionary.

program-data independence - Program-data independence refers to the capability of leaving data intact and accessible regardless of modifications to the database that contains the data.

DBA - Short for Database Administrator, person responsible for maintaining the database. Its main responsibility is to keep the data clean and safe i.e. data doesn't contain wrong or invalid data, and is safe from viruses and is backed up.

end user - Anyone who is not directly interacting with a database, but through some software like website and mobile application.

persisten object - An object of a class in a program, that interacts with the underlying database and is responsible for manipulating the database connected to.

transaction-processing system - A transaction process system is part of a software, responsible for making sure critical business transactions, like crediting or debiting money, either goes through cleanly or doesn't at all.

CRUD are the four main types of operations one can do in a database environment. It stands for creating, reading, deleting and updating.

Variablesallow us to manipulate data through the ___________.

gladu [14]

Answer:

Reference

Explanation:

Variables provide reference to the stored data value.

For example:

int i = 0;

Here i is a variable of type int with an initial value of 0. i is a reference to this stored value 0. Now if I want to update the data, I can do so using this reference.

i = 1;

Now the reference is used to manipulate the stored data and change it to 1. In a similar manner all updates to the value can be done using the variable reference.
