A.) 1280 x 1024 pixels = 1,310,720 pixel

1,310,720 x 3 = 3,932,160 bytes/frame

B.) 3,932,160 bytes x ( 8bits/byte ) / 100E6bits/second = 0.31 seconds

Answer:

a) 3.93216Mb

b) 0.3145728 seg

Explanation:

a) Each color use 8 bits equal to one byte, therefore, three colors uses 24 bits or 3 bytes, additionally, the frame has a size of 1280x1024 equal to 1310720 pixels, using this two results the memory size of the frame is 3 Bytes * 1310720 Pixels = 3932160 bytes equivalent to 3.93216Mb.

b) The speed is equal the frame size divided by the time, to make the operation we convert the 100 mbit/s to Mb/s -> 100/8 = 12.5 Mb/s, therefore, speed = 3.93216/12.5 = 0.3145728 seg

BlackZzzverrR [31]

Answer:

A company requires an Ethernet connection from the north end of its office building to the south end. The distance between connections is 161 meters and will need to provide speeds of up to 10 Gbps in full duplex mode. Which of the following cable combinations will meet these requirements?

ANSWER: Use multi-mode fiber optic cable

Explanation:

MULTI-MODE FIBER OPTIC CABLE

For Ethernet distances up to 100 meters, the Copper CATX cable will do just fine. In the question, we are dealing with a distance of up to 161 meters, so we need an Ethernet extension. LAN extension over fiber optic cable with media converter can be used to convert the Ethernet cable runs from copper to fiber. Multi-mode fiber has a range of 550 meters for 10/100/1000 Ethernet links.

Multi-mode optical fiber is commonly used for communication over short distances, like within a building or on a campus. They are capable of data rate of up to 100 Gbps, which surpasses the requirements in this question. They are more economical in this case as they are not as expensive a the single-mode optical fiber cable. Fiber optic cable has the advantage of being immune to electromagnetic interferences, spikes, ground loops, and surges. This makes it more suited for this purpose.

Write a script that creates a user-defined database role named OrderEntry in the MyGuitarShop database. Give INSERT and UPDATE p

vesna_86 [32]

Answer:

USE MyGuitarShop ;

CREATE ROLE OrderEntry ;

GRANT INSERT ON Orders ,OrderItems TO OrderEntry ;

GRANT UPDATE ON Orders ,OrderItems TO OrderEntry ;

GRANT SELECT ON Orders ,OrderItems TO ALL;

Explanation:

USE MyGuitarShop ;

This statement is used to make MyGuitarShop as the current database

CREATE ROLE OrderEntry ;

This statement creates new role called "OrderEntry".Roles are useful in database to grant permissions for users on particular objects of the database.

GRANT INSERT ON Orders ,OrderItems TO OrderEntry ;

GRANT UPDATE ON Orders ,OrderItems TO OrderEntry ;

above two GRANT statements are used to grant Insert,Update permissions to the Role "OrderEntry " for the tables Orders ,OrderItems.All the users of Role "OrderEntry" are able to grant Insert,Update on the tables Orders ,OrderItems.

GRANT SELECT ON Orders ,OrderItems TO ALL;

above GRANT statement is used to give select permission on specified tables to all users.

zhannawk [14.2K]

Answer:

Follows are the code to this question:

import math as x #import math package

#option a

radius = 10#defining radius variable

print("radius = ", radius)#print radius value

realA = x.pi * radius * radius#calculate the area in realA variable

print("\nrealA = ", realA)#print realA value

#option b

a1 = 3.1 * radius * radius#calculate first area in a1 variable

print("Area 1= ", a1)#print Area

print("Percentage difference= ", ((realA - a1)/realA) * 100) #print difference

a2 = 3.14 * radius * radius#calculate first area in a2 variable

print("Area 2= ", a2)#print Area

print("Percentage difference= ", ((realA - a2)/realA) * 100)#print difference

a3 = 3.141 * radius * radius#calculate first area in a2 variable print("Area 3= ", a3)#print Area

print("Percentage difference= ", ((realA - a3)/realA) * 100) #print difference

Output:

please find the attached file.

Explanation:

In the given Python code, firstly we import the math package after importing the package a "radius" variable is defined, that holds a value 10, in the next step, a "realA" variable is defined that calculate the area value.

In the next step, the "a1, a2, and a3" variable is used, which holds three values, that is "3.1, 3.14, and 3.141", and use the print method to print its percentage difference value.
