Based on the declaration "int b[ 2 ][ 2 ] = { { 1 }, { 3 , 4 } };" given, the value of b[ 1 ][ 0 ] is equal to 3.
<h3>What is Python?</h3>
Python can be defined as a high-level programming language that is designed and developed to build websites and software applications, especially through the use of dynamic commands (semantics), declarations, functions, and data structures.
<h3>What is an int?</h3>
Int is an abbreviation for an integer and it can be defined as a whole number that may either be positive, negative, or zero.
Based on the declaration "int b[ 2 ][ 2 ] = { { 1 }, { 3 , 4 } };" given, we can infer and logically deduce that the value of b[ 1 ][ 0 ] is equal to 3.

Answer:
Switches break up collision domains and routers break up broadcast domains.
Explanation:
- Collision domain depicts the part within a network where a collision can happen.
- Collision occurs when two hosts transmit data packet at the same time within a network. Theses packets collide and the hosts have to resend the data after some time.
- Too many collisions can result in slow traffic speed and can effect network performance.
- So switches break up collision domains between the devices on a network and each port in a switch depicts a collision domain. This reduces the chance of packet collisions between the devices or hosts.
- When data is to be sent to a host, the switch keeps that data frame and waits for availability of the destination host before sending the data frame.
- Moreover full duplex switch mode there is not chance of collision as the transmitting path on one host is the receiving path on other host.
- Broadcast domain contains all the hosts that can reach each other at the Data Link layer via broadcast.
- Routers break up broadcast domains as routers contain separate broadcast domains for each interface.
- Routers do not forward broadcasts from one broadcast domain to other and drop the packet when they detect a broadcast address.
Answer:
rv = "hello"
num_chars = len(rv)
print(num_chars)
Explanation:
*The code is in Python.
Initialize the string rv, in this example I set it to "hello"
Use the len() method to get the number of characters in the rv and set it to the num_chars
Print the num_chars
Note that the result will be 5 in this case, because <em>hello</em> consists of five characters
Answer:
The IT field yeah am sure
Answer: I a reference to the next node
III a data element
Explanation:
A linked list is simply referred to as a linear data structure, whereby the elements would not be stored at memory locations that are together in the sequence.
In simple words, we can simply say that a linked list is made up of nodes in which, every node has a data element and also a link or reference to the next node that is in the list.
Therefore, based on the explanation above, the correct option will be:
I. a reference to the next node
III a data element
