You are an ISP. For the Address Block 195.200.0.0/16 a. If you have 320 Customers that need 128 addresses/customer - will there

be enough addresses to satisfy them? and explain why? b. Say the first block of 64 customers want 128 addresses/customer - what would the address space look like?

Answer:

a. The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.

b. 195.200.0.0/22

Explanation:

195.200.0.0/16

The number of bits to give 512 is 9

2^9=512

2^8=256 which is not up to our expected 320 customers that requires a network ip

Note we have to use a bit number that is equal or higher than our required number of networks.

The number of host per each subnet of the network (195.200.0.0/25) is (2^7)-2= 128-2=126

The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.

b. 64 customers requires  6 bits to be taken from the host bit to the network bit

i.e 2^6 = 64

195.200.0.0/22

The number of host per each subnet of the network (195.200.0.0/22) is (2^10)-2=1024 - 2 = 1022 hosts per subnet

This network meet the requirement " 64 customers want 128 addresses/customer "

VladimirAG [237]

In this activity Morgan is preparing the digital files to a printer  on a DTP project.

Explanation:

DTP project is the creation of documents using page layout on a personal computer. The process of printing digital based images directly to variety of media substrates is known as digital processing.

The digital files like PDFs can be sent directly to digital printing press to print on paper, photo paper, fabric and so on.

They have unique fade rates and different sensitives to the various deterioration mechanisms. DTP is used for graphic designers to create documents.

void dec_bin(int number) {

$\text{int x, y}$;

x = y = 0;

for(y = 15; y >= 0; y--) {

x = number / (1 << y);

number = number - x * (1 << y);

printf("%d", x);

}

printf("\n");

}

int main()

{

int k;

printf("Enter No u wanted to right shift by 4 : ");

scanf("%d",&k);

dec_bin(k);

k = k>>4; // right shift here.

Vladimir [108]

Answer:

1. A. True

2. A. True

3. B. Conceptual.

4. Three (3).

Explanation:

An Entity-Relationship Model is used in databases to describe the structure and relationship between data elements known as entities.

1. True: In the Entity-Relationship Model, relationships can have attributes.

2. True: Attributes are the smallest division of data in ER diagram.

3. Conceptual: the level of abstraction which the Entity-Relationship Model most concerned with.

4. Consider the following relationship involving two entities, students and classes: A student can take many classes. A class can be taken by many students. The number of tables which can be used to represent this relationship in a schema is 3 because we are having three (3) parameters which are simply the students and the two entities.

In database management, the term "schema" is used to denote a representation of data.

A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.
