C should be the answer to this I hope that this helps
Answer:
The correct answer to the following question will be option c. Cat-6.
Explanation:
Cat-6: A standard version of twisted pair cable for physical layer of networking and for Ethernet is, Cat-6 (Category 6) cable.
- Cat-6 will be adaptable with the Category 5/5e and 3 standard of cables, and the standard specifies the performance of cable compared to 100 MHz up-to 250MHz for Cat 5/5e.
- So, if you are looking for the best cabling system to use while installing the Gigabit Ethernet, Category 6 will be the suitable one.
Answer:
1. 'NOT(TRUE AND FALSE) AND TRUE'
3. 'NOT (TRUE AND TRUE) OR TRUE'
Explanation:
We can go through each option to find out which statements will result in a 'TRUE' value.
1. <u>'NOT (TRUE AND FALSE) AND TRUE':</u>
'TRUE AND FALSE' inside the parentheses will result in 'FALSE' since the Boolean operator 'AND' requires both terms to be 'TRUE' for the resulting value to become 'TRUE', otherwise it returns 'FALSE'.
'NOT (TRUE AND FALSE) AND TRUE' now becomes 'NOT FALSE AND TRUE'. The Boolean operator 'NOT' will return the opposite of the term given, so 'NOT FALSE' becomes 'TRUE'. This leaves us with 'TRUE AND TRUE' which returns 'TRUE'.
2. <u>'NOT (TRUE AND TRUE) AND TRUE':</u>
'TRUE AND TRUE' inside the parentheses will result in 'TRUE', leaving us with 'NOT TRUE AND TRUE'. 'NOT TRUE' will give us 'FALSE', resulting in 'FALSE AND TRUE'. The resulting value of 'FALSE AND TRUE' is 'FALSE'.
3. <u>'NOT (TRUE AND TRUE) OR TRUE':</u>
Again, 'TRUE AND TRUE' inside the parentheses will result in 'TRUE', leaving us with NOT TRUE OR TRUE'. The Boolean operator 'OR' requires only one term to be 'TRUE' for the resulting value to become 'TRUE'. This means that this statement will return 'TRUE'.
Hope this helps :)
Answer:
Star topology
Explanation:
<u>Star topology</u> : In a network,when different hosts(pc,laptops) are connected to a single communication point called server/hub/switch/computer.
Advantages of star topology :
- When a single node is failed,it will not affect the entire system,the other nodes work as earlier.
- We can add new nodes easily,without affecting the network.
- Monitoring of the network eases,as you can only check switch/hub for it.We don't have to check each node at the time of failure.
- Performance is better than other topology because the transfer of data is directly transferring from hub to a node.
- Less complexity of architecture of network.The central hub is connected to each node no node-node connections are there.
Answer:
A: cases can't have a test condition
Explanation:
Under the hood, switch statements don't exist. During the mid-stage of compilation, a part of the compiler will lower the code into something that is easier to bind. This means that switch statements become a bunch of if statements.
A case in a switch statement acts upon the switch value. Think of the case keyword as the value you pass into the switch header:
int x = 10;
switch (x)
{
case (x > 2):
// Code
break;
}
// Becomes
if (x(x > 2))
{
// Code
}
// Instead do:
switch (x)
{
case > 2:
// Code
break;
}
// Becomes
if (x > 2)
{
// Code
}
