Nana76 [90]

Answer:

1. PANs uses Star Topology.

2. LAN uses four topology (Bus, Ring, Star and Tree).

3. MAN uses Star Topology.

4. WAN uses Bus topology.

Explanation:

1. PAN is the personnel area network, in which different personnel devices of a person are connect to each other with the help of the central computer with the help of Bluetooth, WiFi or some other medium. The central computer will work like a hub and all the devices are directly connected to the central PC. It is same as the ring topology where all the devices are connected to the central PC. So we can say that, PANs use star topology.

2. LAN is the local area network that has been established with in the premises of the organization. In this type of network, four typologies involve to complete the network connection. First is star topology, that is used to connect all the devices with the switches. Then Bus topology is used to connect all the switches with the single main cable. Ring topology is involved to connect all the switches with each other. Tree topology is used to connect different block if the organization in the form of branch to connect the central router or switch.

3. MAN is the Metropolitan Area Network which is comprise of different LANs. All the LANs are connected to the Router in the form of Star topology.

4. WAN is the wide area network. In WAN different MANs are connected to the network through single cable. This type of network uses Bus topology.

zhenek [66]

Answer:

C. Hardware resources are dynamically allocated as use increases.

Explanation:

Cloud computing is a technique organisations to store and retrieve resources in a remote central database with secure access over the internet. It is able to access large data storage resources that would have cost more if they had implemented one for themselves.

A database or data centre is a online group of servers that is in a subscribed service to authorised users. Storage hardware allocation is dynamic to users, which means that another storage location in issued on every duration of subscription, making it easy to add more storage infrastructure. This defines the scalability of data centres.

NNADVOKAT [17]

Answer:

a. Comparison of if-else and elif:

if else follow as:

If (Condition)

{

In case if condition true, expression in this section executes

}

else

{

In case condition is false, expression in this section executes

}

elif Statement follows as:

If (Condition)

{

In case if condition true, expression in this section executes

}

{

in case, condition is false, move to elif block

elif (Condition)

{

In case elif condition true, expression in this section executes

}

else

{

In case elif condition is false, expression in this section executes

}

}

Explanation:

In if else, program first check the condition in "if statement", if condition is true it move into the body of "if " and execute the expression. If the condition is false it moves to the body of "else" and execute the expression.

elif is another block of condition in If else condition,It works as in "if statement" if the condition is true the program executes the expression of body of "if body". If the condition is false, it moves to another block of "elif", where it again check some other condition found in "elif statement". If the condition of "elif statement" is true it executes the expression of "elif body" otherwise in case of false condition it execute the expression in "else body".

It follows as: if - elif-else

Answer

b. the relational operators

Relation operators are the operators that are need in the expression to establish relationship between different operands of the expression.

Explanation:

In few expressions, their are some operators used to establish or show the relationship between different operands. These operator could be Equal (=), Greater than(>), Less than (<), Greater than equal to (>=) and Less than Equal to (<=).

These operators can be used in conditional statements that are used to check the relationship between operands and values through these operators.

Example

if (a>5)

{

if value of is greater than 5 then body of if will execute.

}

else

{

If value of a is less or equal to 5, this section will execute.

}
