Answer:

(a) The output is -1

(b) The output is 32

Explanation:

Given: The above code

Solving (a): The output when 1, 1 and 1 is passed to the function

From the question, we have: print(mystery(x))

This means that only the value of x (which in this case is 1) will be passed to the mystery function

(a, b = 8, c = -6) will then be seen as: (a = 1, b = 8, c = -6)

$2 * b + a + 3 * c = 2 * 8 + 1 + 3 * -6$

$2 * b + a + 3 * c = -1$

<em>The output is -1</em>

Solving (b): The output when 8, 6 and 4 is passed to the function

From the question, we have: print(mystery(x,y,z))

This means that values passed to the function are: x = 8, y = 6 and z = 4

(a, b = 8, c = -6) will then be seen as: (a = 8, b = 6, c = 4)

$2 * b + a + 3 * c = 2 * 6 + 8 + 3 * 4$

$2 * b + a + 3 * c = 32$

<em>The output is 32</em>

The performance of a client-server system is strongly influenced by two major network characteristics: the bandwidth of the netw

Rama09 [41]

Answer:

A bandwidth is the maximum rate of transfer of data across a given path

Latency refers to the delay of data to travel or move between a source and destination

An example of a high bandwidth and high latency network is the Satellite Internet connectivity.

An example of a low bandwidth and latency network is the telephone system connection.

Explanation:

Solution

Bandwidth: Bandwidth determines how fast data can be transferred for example, how many bits/sec it can transport.

Latency: It refers to the delay or how long it takes for data to travel between it's source and destination.

An example of a high bandwidth and high latency network is the Satellite internet connection.

Satellite internet connection: This is responsible for the connectivity of several systems, it has a high bandwidth, since satellite are in space, due to distance it has a high latency.

So, satellite internet connection is compensated with high latency and high bandwidth.

An example of a low bandwidth and low latency network is the Telephony network.

Telephone/telephony internet connection: This connection does not have much data for transfer. it has low size audio files of which a low bandwidth range. also for both end or end users to understand and talk to each other, it has low latency.

public Card(int value, String Suit) {

self.value = value;

// Check Suits value

if ((Suit == "hearts") || (Suit == "spades") || (Suit == "clubs") || (Suit == "diamonds"))

self.Suit = Suit;

else {

Suit = "none";

throw new IllegalArgumentException("no card of this type exists.");

}

Neporo4naja [7]

The OC level is primarily used as a regional ISP backbone, and occasionally by very large hospitals, universities, or other major enterprises is <u>OC-48.</u>

<u></u>

<h3>What is the greatest amount of throughput provided by an OC 12?</h3>

OC-12 is a network line with communication speeds of up to 622.08 Mbit/s (payload: 601.344 Mbit/s; overhead: 20.736 Mbit/s). OC-12 lines are generally used by ISPs as wide area network (WAN) connections.

<h3>When using frame relay What is the appellation of the identifier?</h3>

A data-link connection identifier (DLCI) determines the Frame Relay PVC. Frames are routed through one or more virtual circuits determined by DLCIs.

Each DLCI has a permanently configured switching path to a particular destination

The readline method reads text until an end of line symbol is encountered, how is an end of line character represented

zhannawk [14.2K]

Answer:

Explanation:

readline() method is used to read one line from a file. It returns that line from the file.

This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.

So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.

For example if the file "abc.txt" contains the lines:

Welcome to abc file.

This file is for demonstrating how read line works.

Consider the following code:

f = open("abc.txt", "r") #opens the file in read mode

print(f.readline()) # read one line from file and displays it

The output is:

Welcome to abc file.

The readline() method reads one line and the print method displays that line.
