Segundo o padrão da National Institute of Standards and Technology a alternativa correta é a letra E) 400 músicas. Segundo o padrão disposto acima, dois Giga Bytes equivalem à dois mil Mega Bytes, assim, se cada música tem exatos 5MB, podemos chegar ao total de músicas que podem ser gravadas em um PenDrive de 2GB livres do seguinte modo :
\(x=\frac{2000 MB}{5MB}\)\(;x=400\)
A evolução da microeletrônica possibilitou uma capacidade de armazenamento cada vez maior a cada ano. O desenvolvimento de novas tecnologias na área permite também que os produtores possam produzir músicas, fotos e vídeos com cada vez mais qualidade (consequentemente mais pesada).

Explanation:
The two main purposes of a good web page design is responsiveness and intuitive. A webpage needs to be designed in such a way that the individual using it can easily find what they are looking for and understand what each function in the webpage does without having to ask for help or go through an extensive tutorial. They need to be able to use the website for the first time and immediately be able to use it as if they have used it countless times before. The webpage also needs to be designed with responsiveness in mind. So much so that the webpage runs fluently, loads images fast, and scales to the size of the monitor correctly. As a rule the webpage should not take longer than 2 seconds to load.

Transmissions in wireless networks do not allow for collision detection but try to avoid collision. Briefly describe this process and explain why it is termed as unreliable.
Transmissions in wireless networks do not allow for collision detection but try to avoid collision and also It is especially crucial for wireless networks since wireless transmitters desensing (turning off) their receivers during packet transmission prevents the option of collision detection using CSMA/CD.
What are the different types of wireless transmission?Wireless transceivers are unable to send and receive on the same channel simultaneously, hence they are unable to identify collisions. This is because the send power (which is typically around 100mw) and the receive sensitivity have such a huge disparity (commonly around 0.01 to 0.0001mw).
Therefore, Infrared, broadcast radio, cellular radio, microwaves, as well as communications satellites are examples of wireless transmission media that are used in communications. Infrared (IR), which is a wireless transmission medium that uses infrared light waves to transmit signals, was covered previously in the chapter.

i. Suppose tree T is a min heap of height 3.
- What is the largest number of nodes that T can have? _____________________
- What is the smallest number of nodes that T can have? ____________________
ii. The worst case complexity of deleting any arbitrary node element from heap is ___________
Answer:
i. A min heap of height 3 will have a root node with two children, each of which has two children of its own, resulting in a total of 7 nodes at the bottom level. Therefore:
The largest number of nodes that T can have is 1 + 2 + 4 + 7 = 14.
The smallest number of nodes that T can have is 1 + 2 + 4 = 7.
ii. The worst case complexity of deleting any arbitrary node element from a heap is O(log n), where n is the number of nodes in the heap. This is because deleting a node from a heap requires maintaining the heap property, which involves swapping the deleted node with its child nodes in order to ensure that the heap remains complete and that the heap property is satisfied. This process requires traversing the height of the tree, which has a worst-case complexity of O(log n).

Answer:1.) Analog
2.) Digital
3.) Pixels
4.) Local Area Network
5.) Bus
6.) Slots
Explanation:
The answers to the given questions are:
Analog Sound
Digital Sound
Pixels
Local Area Network (LAN)
Bus
Slots
Physical waves that travel through matter are referred to as analog sound waves.
These waves are continuous and represent the variations in air pressure caused by sound.
Analog sound is used in older forms of audio technology like vinyl records and cassette tapes.
Hence, Analog Sound are physical waves that travel through matter.
Electrical impulses represented as 0's and 1's are characteristic of digital sound.
In digital sound, sound signals are converted into binary code (0's and 1's) which can then be processed and transmitted by computers and other digital devices.
Hence, Digital Sound are electrical impulses represented as 0’s and 1’s.
The images seen on a monitor or screen are made up of tiny dots called pixels.
Each pixel represents a single point of color or light, and when millions of pixels are combined, they create the images and videos that we see on digital displays.
Hence, the tiny dots that make up the images seen on a monitor called Pixels.
A Local Area Network (LAN) is a network that is confined to a small geographic area, such as within a building, a campus, or a specific group of interconnected buildings.
LANs are commonly used to connect computers and devices within a limited area.
So, Local Area Network is a network that is confined to a small area.
A bus is a subsystem in a computer that facilitates the transfer of data between different computer components (such as the CPU, memory, and peripherals) or between different computers in a network.
Buses can be thought of as communication pathways that enable the flow of information.
Hence, Bus is a subsystem that either transfers data between computer components or between computers.
Slots are openings in a computer's chassis or motherboard where printed circuit boards (also known as expansion cards) can be inserted. These expansion cards can add various capabilities to the computer, such as graphics processing, sound, network connectivity, and more.
Hence, in a computer where printed circuit boards can be inserted to expand the computer’s capabilities called slots.
