Answer:

Cell.

Explanation:

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.

Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.

Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data.

In the field of telecommunication, all telecommunication setup are designed and developed to make use of two network devices: one device is typically used for the transmission of data while the other device is used to receive data that are sent on the network.

Generally, cell towers are tall poles that are used to transmit frequencies to mobile phones.

Assume that you have an array of integers named arr. Which of these code segments print the same results?
tresset_1 [31]

Answer:

II and III only

Explanation:

In Code segment II, the output of the array will be started form arr[0] and ends at the arr[length]. Because loop starts from 0 and ends at length of array. This will print the full array data.

In code segment III, the output will be all values of array as loop starts form first index and ends at last index.

On the other hand I code segment prints all array values except last value of the array. As the loop shows that, it will terminate at second last value of the array.

List the five parts of a system.describe them.
dem82 [27]
The five main parts of a system are: 

1. The CPU
The CPU is the brain of the computer. It is the main part that does all th thinking and processing.

2. RAM
which stands for Random Access Memory. As implied in its name, it can be accessed at random times by the CPU. When you open a program, all the scripts and codes that are running need to be run of a separate memory bank. Thus, the RAM takes part.

3. Drives
Hard Drives, SSDs, USB Drives, and SD cards are all forms of main computer memory. That is where the computer stores the OS, your files, and its instructions.

4. Inputs/Outputs
By inputs and outputs i mean hardware, like Speakers (ouput), Monitors (output), Keyboard (input), and Mouse (input).

5. OS
The OS is the Operating System (e.g. Windows, Linux, Mac), which is the main instructions for the computer. It is what makes your computer usable.

Write down the pseudo code for a brute-force algorithm to compare elements in array A with elements in array B.
Thepotemich [5.8K]

Answer:

def brute_force(array1, array2):

   for item in array1:

       for element in array 2:

           if element == item:

               print(f"{element} and {item} are a match")

Explanation:

A brute-force algorithm is a direct-to-solution algorithm that searches and compares variables. It is like trying to unlock a safe but not knowing its four-digit combination, brute-force starts from 0000 through 9999 to get a match.

The python program implements the algorithm using two nested for loops. The first loop iterates over array1 while the second, over array2. For every item in the first array, the program loops through the length of the second array. For every match, the items are printed on the screen.

In which patten the modern computer work ?​
umka21 [38]

Answer:

Von Neumann describió el fundamento de todo ordenador electrónico con programas almacenados. Describía, a diferencia de como pasaba anteriormente, como podía funcionar un ordenador con sus unidades conectadas permanentemente y su funcionamiento estuviese coordinado desde la unidad de control (a efectos prácticos es la CPU). Aunque la tecnología ha avanzado mucho y aumentado la complejidad de la arquitectura inicial, la base de su funcionamiento es la misma y probablemente lo seguirá siendo durante mucho tiempo. El artículo viene acompañado de una representación gráfica del funcionamiento.
