Answer:
The correct answer is A.
Explanation:
B is true if the two nodes are descending from the same parent node, they are called sibling nodes.
C is true, the nodes which do not have any nodes branching from them are called leaf nodes and mark the end of that specific branch.
D is true, a node tree is defined as nonlinear set of nodes growing downwards which are linked together.
The false option is A, a node in a node tree does not have to contain at least two links, it can be a leaf node.

The answer to your question is software.
The four components of computer are explained clearly.
<u>Explanation:</u>
- Hardware is the electrical physical parts that a computer system needs to function. It organizes all the process by a circuit board that operates within a PC or laptop; built with the "motherboard", "graphics card", "CPU (Central Processing Unit)", "ventilation fans", "webcam", "power supply", and so on. Without hardware, there is no means of running the necessary software that makes computers so valuable.
- Software is a program that facilitates a computer to execute a particular task, as objected to the hardware. Computer software has to be "stored" into the computer's storage (such as a hard drive, memory, or RAM). Working computer systems segment software into three major classes: system software, programming software, and application software.
- A user is a person who handles a computer or network service. Users of computer and software output regularly require the technical expertise needed to fully know how they operate.
- Data is defined as bases or figures, or knowledge that's saved in or utilized by a computer. This data will be in the form of text documents, images, audio clips, software programs, or other types of data. Computer data may be prepared by the CPU and are saved in files and folders on the hard disk.
Answer:
The Packets can be arrived out of an order from the Internet Protocol layer.
So, whenever the out of an order packets would be received then, it would be generated the duplicate ACK's, if we perform the re-transmission after the first duplicate ACK would be lead the senders to introduced too many redundant packets in the networks.
Explanation:
- All the bytes, in the Transmission Control Protocol connections, are the numbered, from the beginning at the randomly choose the initial sequence number (ISN).
- The SYN packets consumes the one sequence number, so the data will be actual and it begins at the ISN+1.
- The receivers ack's sequences the number x acknowledged the receipts of all the data bytes that is less than byte the number x.
