I would go with a funnel cloud on this one. It is the most common sign although it does not guarantee a tornado. Most tornadoes that reach the ground do expand from funnel clouds, but a condensation funnel cloud formation is not absolutely necessary for a tornado to form.

True or False: The major advantage of Arrays over ArrayLists in Java is the fact that while ArrayLists are fixed in size, an Arr
Hatshy [7]

Answer:

False

Explanation:

It's the other way round actually. Arraylists do not have fixed size and can increase or decrease in size as needed. On the other hand, Arrays are fixed from when they are declared; they have a particular size that number of elements cannot go beyond.

An arraylist in Java is a class that is part of a Java collection framework(java.util) that can have variable sizes and only store objects, not primitive data like strings or integers. An array is a data structure in Java and can store both primitive data and objects, while having a fixed size at declaration.

kicyunya [14]

Answer:

Data link layer of OSI model is creating the erroneous segments

Explanation:

The Open System Interconnection (OSI) model is a conceptual framework about how communication occurs between devices over the Internet. It has seven layers, (Physical, Data, Network, Transport, Session, Presentation and Application layer). The purpose of this hierarchical layer system is to understand the structure of communication between devices and do troubleshooting easily if a fault occurs. As in this question, Marry is troubleshooting her company LAN network. She finds out that data segments that the client is encoding are resulting in errors in the encoding. Now the question arises, how she found the cause of the error. The OSI model helps her in understanding the problem.

As you know, the data link layer of the OSI model is responsible for the encoding and decoding of data segments. This layer ensures the reliability of the physical layer, and responsible to provide error-free transfer of data from one node to another on a network. It is also responsible for frame synchronization and flow control. The data link layer is divided into sub-layers:

1. Media Access Control Layer: this layer controls how a computer on the network gains access to the data and transmission permission.

2. Logical Link Control Layer: This layer controls frame synchronization, error checking and flow control.

Therefore, Marry founds data link layer of the OSI model is creating the erroneous segments in encoding.

Part of the central processing unit
AveGali [126]

Answer:

Explanation:

The arithmetic logic unit (ALU) performs mathematical, logical, and decision operations.  It can be divided into the arithmetic unit (responsible for addition, subtraction, multiplication and division).  And logic unit (responsible for comparing, selecting, matching and merging different data or information).  The power and efficiency of the CPU depends on the design of the ALU.  

Next up is the control unit (CU) which directs all the processor’s operations.  It’s where the CPU reads and interprets requests from memory and transforms them into a series of signals (binary).  Then it sends the operation to various parts of the laptop as instructed.  The CU calls the ALU to perform the necessary calculations.  It also coordinates all input/output devices to transfer or receive instructions.

The main job of the memory unit is to store data or instructions and intermediate results.  It’s divided into primary memory and secondary memory to supply data to other units of the CPU.  It allows the CPU to perform functions requested by programs like the operating system without having to ask RAM.

Another element of the CPU not depicted in the diagram is transistors.  To carry out calculations, binary information (ones and zeros) is stored in these microscopic switches.  They control the flow of electricity depending on whether the switch is ON or OFF.  Signals turn off and on different combinations of transistors to perform calculations.  A very thin silicon chip can contain several hundred million transistors.
