Answer:
Option C is the correct answer for the above question.
Explanation:
The ciphertext is a text which is formed from an original text and can be called a duplicate text which has no meaning for the other user. This can be formed with the help of encryption technology. Encryption technology is a technology that uses some mythology to convert the original data into other text data (which is also called a ciphertext) because no one can able to hack the data.
The above question asked about the term which is called for the text when it is converted from original data. That text is known as ciphertext which is described above and it is stated from option c. Hence option c is the correct answer while the other is not because--
- Option 'a' refers to the public key which is used to encrypt the data.
- Option b refers to the private key which is also used for encryption.
- Option d refers to the sniffer which is not the correct answer.
Answer:
The reasonable power will be "0.234 μW".
Explanation:
The given values are:
P = 15 μW
d = 175 m
As we know,
Propagation follows inverse cube power law, then
∴ 
⇒ 
On substituting the estimated values, we get
⇒ 
⇒ 
Now,
"P" at 0.7 km or 700 m from BS will be:
⇒ 
⇒ 
⇒ 
Answer:
Press the Shift key, then press the Home key.
Explanation:
This is because Home key take you to a beginning of a line and shift selects.
Have a nice day!

Answer:
Physical layer is the first layer of OSI model. The detail about physical layer and its parts is given below in explanation section.
Explanation:
The physical layer is the lowest and first layer of the Open Systems Interconnection Model (OSI). The physical layer is used for the transmission of data in bit forms. For transmission of data between devices, it uses the transmission medium that is either wired or wireless.
In the wired cable the component of the psychical layer include cable and connectors that are implemented for carrying data from one place to another or simply to transmit data between two connected devices. The wireless transmission medium is used to transmit data in the form of electromagnetic signals for carrying data into a stream of bits. Over past advancements in networking technologies, rapid growth has been seen in wireless data transmission and Wi-Fi and Bluetooth communication are few names of it.
Components/Parts of Psychical Layer
In the physical layer, the hardware components used it in are the network interface cards, connectors and interfaces, intermediate devices, modems, and cables to facilitate the transmission of data between devices or from source to destination.
- The network interface card (NIC)
NIC is a component installed in the computer to connect it to any available devices over the network.
- Connectors and Interfaces
Connectors and interfaces are used to connect cables that are being used for transmission of data from one source to another. The decision to choose connectors and interfaces depends on the type of cable. Typical examples are RJ-45, RJ-11, V.35, HDMI, etc.
Cables are the physical components of the physical layer that carry optic or electromagnetic signals for transmission of data from source to destination in the network.
The intermediate devices are hubs and repeaters etc. The functions of these devices are to amplify or generate the signal at the intermediate point in a network.
True robots that have integrated ML can store data in specialized arrays which can be processed by the algorithms to give the output as their behaviour.
