Answer:

12,000,000 bytes.

Explanation:

If we want to store an uncompressed binary image, assuming that we will use 256 different levels to represent all tones in a monochromatic image, each pixel will be stored as an 8-bit sample, i.e. one byte per pixel.

The complete image will have 4000 pixels wide by 3000 pixels height, so an entire image will need 3000*4000= 12,000,000 pixels.

As we will use 8 bits= 1 Byte per pixel, we will need to store 12,000, 000 bytes for a complete uncompressed monochromatic (white & black) image.

Describe encryption at gateways in thePresentation layer of the OSI Reference Model

puteri [66]

Answer:

In the presentation layer of the OSI reference model provides a variety of coding and functions that can be applied in application layer data. Information send by the application layer are ensured by these functions. As, presentation layer is the important layer in the OSI reference model because it is responsible for important services like data compression, data conversion, decryption and encryption.

Encryption at gateway is defined as, when the important data is first encrypted using protocol and then it is transferred in the network. And gateway re-director operates in the presentation layer.

In a _____ network, each device on the network is attached to a central router. If the router fails, then the other devices will

Damm [24]

Answer:

In a STAR TOPOLOGY network, each device on the network is attached to a central router. If the router fails, then the other devices will be unable to communicate, but if only one connected device fails, then all other devices will still be able to communicate.

Explanation:

In this type of topology all the computers are connected to a single router through a cable. This router is the central node and all others nodes are connected to the central node.

// This pseudocode segment is intended to compute and display

Finger [1]

The pseudocode to calculate the average of the test scores until the user enters a negative input serves as a prototype of the actual program

<h3>The errors in the pseudocode</h3>

The errors in the pseudocode include:

Inclusion of unusable segments
Incorrect variables
Incorrect loops

<h3>The correct pseudocode</h3>

The correct pseudocode where all errors are corrected and the unusable segments are removed is as follows:

start

Declarations

num test1

num test2

num test3

num average

output "Enter score for test 1 or a negative number to quit"

input test1

while test1 >= 0

output "Enter score for test 2"

input test2

output "Enter score for test 3"

input test3

average = (test1 + test2 + test3) / 3

output "Average is ", average

output "Enter score for test 1 or a negative number to quit"

input test1

endwhile

output "End of program"

stop
