Tom [10]

Answer:

systems design phase.

Explanation:

In a systems development life cycle (SDLC) model, the purpose of the systems design phase is to create a physical model that will satisfy all documented requirements for the system.

This ultimately implies that, that system design involves determining the overall system architecture, which is typically comprised of hardware, end users, physical processing components, software, and the communication channel that will effectively and efficiently satisfy the essential requirements of the system.

The system inputs and outputs will be designed along with a plan of the way the system's features will be navigated.

Basically, system design is divided into two groups;

I. Logical design.

II. Physical design.

The design of service systems is the process involved in planning, creating infrastructure, building communication, organizing staffs and standardization of a system so as to improve its quality and business relationships between the service provider and its clients. A characteristic that can be used to guide the design of service systems is to ensure services cannot be inventoried.

Assume that the int variables i and j have been declared, and that n has been declared and initialized.
Sonja [21]

Answer:

The code to this question can be given as:

code:

for(i=1;i<=n;i++)   //for loop column

{

for(j=1;j<=i;j++)       //for loop for rows

{

printf("*");         // print asterisks

}

printf("\n");     //line break

}

Explanation:

We know that variable i,j, and n is already declared and n variable has initialized a value. So, we write the code that is given above. In this code, we use a nested loop. In this code, we use two loops that are a loop (i)for column and j loop for rows. for print asterisks triangle we use two for loop. For that, we use two-variable (i,j) that is already declared. We assign the value in (i) loop that is 0 and checks that (i) is less than equal to n and increment of (i) by 1. In this loop, we use another loop that is (j) loop. It also starts from 1 and checks that (j) is less than equal to (i)and increment of (j) by 1. In that loop, we print asterisks end of (j) loop. In (i) loop we use ("\n") for line break end of (i) loop.

Which CIDR network has the smallest possible number of hosts? a. 123.0.0.0/8 b. 123.45.0.0/16 c. 123.45.67.0/24 d. All have the
Lina20 [59]

Answer:

CIDR is based on a variable-length subnet masking technique, which allows a new method of representation for IP addresses. Routing prefix is written with a suffix number of bits of the name, such as 123.0.0.0/8, as the CIDR network has the smallest possible amount of hosts.

Explanation:

CIDR ( Class Inter-Domain Routing ) It is a method that is allocating IP addresses and routing the IP. CIDR is introduced in 1933 and replace the architecture of network design on the internet. CIDR slows down the growth of the routing across the web and helps to slow the IP addresses such as IPv4 addresses.

CIDR consists of two groups of bits in the address. In the new age, the network prefix identifies the whole network. This is used as the basis of routing between IP networks and allocation policies.

IPv4 in-network prefix is 8-bit groups.

A typical IPv4 address is 192.168.0.5 the lowest value is 0, and the highest value is 255

In the given choices, 123.0.0.0 / 8 of the possible smallest number of hosts.
