Some protocols have multiple algorithms to choose from for e.g., cryptographic purposes. During connection set up, client and server negotiate which one they'll use.

One example is the set up of a TLS connection. During the handshake, the client shares a list of its supported ciphers (the 'ciphersuites'). The server responds by indicating the best one that both sides support.

1. In the powerpoint presentation, we have to click "Slide Show" tab in the ribbon and then click on the "Set up slide show" on the Set Up bar.

2. The set up slide show dialogue box will pop up. In this we have to check or tick on the "Loop continuously until 'Esc' " in the "Show Option" and then click 'OK'

3. Now in the "Slides" preview side panel, we have to click the 1st slide , then Press and hold the 'Shift' key and then click the last slide. This selects all the slides.

Answer:

Sequence

Explanation:

Uipath is an RPA(Robotic process automation) software that is used by IT professionals and business executives in automating routine or iterative tasks in an organization. Uipath process projects incorporate different workflow types which include :sequence, flowchart, state machine and global exception handler.

As data travels further over a wavelength or frequency, what goes down?

LUCKY_DIMON [66]

As data travels further over a wavelength or frequency, the radiation type goes down.

<h3>What is an electromagnetic spectrum?</h3>

An electromagnetic spectrum can be defined as a range of frequencies and wavelengths into which an electromagnetic wave is distributed into.

In Science, the electromagnetic spectrum consist of the following types of energy from highest to lowest frequency and shortest to longest wavelength:

Gamma rays

X-rays

Ultraviolet radiation

Visible light

Infrared radiation

Microwaves

Radio waves

In this context, we can infer and logically deduce that as data travels further over a wavelength or frequency within the electromagnetic spectrum, the radiation type goes down.
