Answer:

The two designs differ in the operating systems

Explanation:

The layered and non-layered designs have intricate differences between them.

In the layered design, the virtualization is the main factor that controls the kernel level virtualization in the system. In addition, the operating system hosts is mainly run on a special type of altered kernel that basically contains the operating system for controlling and managing the virtual memory.

However, in the non-layered design, the system virtualization is the architecture design of the Linux system and the UNIX operating system. In addition, the core of the operating system is the kernel that handles all the interactions between the operating software and the hardware.

Answer:

In the layered design, the virtualization is the main factor that control the kernel level visualization in the system. The operating system host is mainly run on the special type of altered kernel that basically contain the operating system for controlling and managing the virtual memory (VM).

In the non layered design, the system virtualization is the architecture design of the Linux and UNIX based operating system. The core of the operating system is the kernel that handle all the interaction between the operation system and the hardware.

You are working with a database table that contains data about music. The table includes columns for track_id, track_name (name

german

The statement that completes the query is: bytes / 1000 AS kilobytes

<h3>SQL (Structured Query Language)</h3>

This is the language that is used to retrieve, update, and store data in the database.

<h3>Columns</h3>

From the question, we have the following table columns

track_id
track_name (name of the music track)
composer
bytes (digital storage size of the music track

To retrieve data from the bytes column, we make use of:

SELECT bytes ......

From the question, we understand that this column should be divided by 1000, and the AS command should be used.

So, the query becomes

SELECT bytes / 1000 AS kilobytes .....

Hence, the statement that completes the query is: bytes / 1000 AS kilobytes

Your company wants to use an IoT device but wants to make sure it does not interfere with other RF devices that use the 2.4 GHz

jonny [76]

Answer:

C. Z-wave

Explanation:

The Z wave is a wireless communications protocol used primarily for automation. The Z- wave operates using a mesh network and then uses low energy radio waves to communicate from appliance to appliance.

The Z wave operates on a lower frequency than most other popular RF devices, thus making interference nonexistent.

The range of the Z-wave is 100m. Hence, it can give a perfect coverage from the base station to the company.

Option A is wrong . This is because the Zigbee is insecure and has a low coverage range (10m-20m). This means that there are possibilities of interference and also improper coverage beyond 50 m.

Option B is wrong. This is because Bluetooth devices are insecure, can loose connections under certain conditions. They have a range of 10m which is a lot lower than 50m benchmark.

Option D is wrong. NFC stands for Near Field Communication. This means its range is practically about 4cm and it cannot be used for long ranges as the company intends.

When a Select Case statement executes, the value of the test expression is compared with the values that follow each of the ____

goldenfox [79]

Answer:

Case

Explanation:

In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.

Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.

For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.

A Select Case statement can be defined as a conditional statement that avails software developers or programmers the ability to test a variable by comparing it with a list of values.

In a Select Case statement, each variable is referred to as a Case.

Generally, when a Select Case statement executes, the value of the test expression is compared with the values that follow each of the Case keywords.
