Answer:
Explanation:
The following code is written in Python and it is a very simple function/program that takes in an array of strings as a parameter called names. This array is then passed the built-in sort function which automatically sorts it in ascending alphabetical order. Finally, the print method is called on the names array to print all of its elements out.
def sort_strings(names):
names.sort()
print(names)
Answer:
A) Switch
Explanation:
In Java and most programming Languages, A Switch Statement provides a multi branch statements which provides a more flexible way for transfer of execution to the branch that fulfills the condition of the expressed value. This is a better way of handling if...elseif....else statements. In this way, a variable is tested for equality against some values. Variables used in switch expressions can only be primitives (int, byte, char), enums and strings. A switch statement has
1. A default statement (optional), appears at the end of the switch and acts as the else condition.
2. A break statement which terminates the switch when reached.
The syntax of a switch statement is given below:
switch(expression) {
case x:
// code block
break;
case y:
// code block
break;
default:
// code block
}
Complete Question:
The main disadvantage of using this device is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.
Group of answer choices
a. Router
b. Switch
c. Bridge
d. Hub
Answer:
d. Hub.
Explanation:
A hub can be defined as a layer one (physical) device used for connecting various network devices such as switches and routers in a local area network (LAN). It comprises of many ports which are used for connecting segments of a local area network (LAN). Hubs are generally considered to be unintelligent because when frames are received at a port, it is then copied to every other connected port on the network.
<em>Hence, the main disadvantage of using a hub is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.</em>
