Why is it important to have the following parts of a letter sender address and the receiver address?
With no RECEIVER address the postal systems won't know where to DELIVER the letter. With no SENDER address the postal systems won't know where to RETURN the letter if the intended receiver moved (and left no forwarding address).
The communication process begins with who transmits the message?
The communication process begins when a person has a message. It continues if the message is transmitted through a medium. Communication is complete if a receiver receives the message and understands it.
Which of the following is a prerequisite for effective digital communications?
Both the sender and receiver must use the same line encoding scheme There should be no DC component present in the signal
Types of Communication as to levels of source and receiver?
level of source receiver
What is the purpose of a channel encoder and decoder in modern communication systems?
channel encoder inserts additional information to the transmitted bit stream to facilitate error detection and correction at the receiver. channel decoder is quite opposite to the channel encoder which transmits desired data after the error detection and correction .
What is the purpose of a communications receiver?
A communications receiver is a radio receiver used for communications. It receives a transmitted signal and sends it further along the line till it is converted into sound.
What are the parts of a Doppler Radar?
Same as the "regular" radar, except that the receiver is a bit different. In regular radar, the receiver looks for the returning signal on the frequency the transmitted pulse was sent out. Yes, it sees" Doppler shifted signals, but with decreasing sensitivity. And it does little with them but combine them with the signal on the frequency of the transmitted pulse. With Doppler radar, the receiver looks for a "band" or group of frequencies around the frequency at which the transmitted pulse was sent out. These "nearby" frequencies represent returns from materials or substances that are moving relative to the transmitter (toward or away from it). And the receiver works with a microprocessor based "analyzer" to paint a picture based on those returning signals that are near the frequency of the transmitted signal and not right on it. Basically, radar has a transmitter, the waveguide to the antenna, the antenna itself, and the receiver. The receiver is plumbed into the same waveguide the transmitter is connected to, but there is a junction (like a "T") where the transmitter and receiver are connected that is capable of directing the transmitted signal out along the waveguide and keeping it from going into the receiver, and then allowing the returned signal to get to the receiver without being "lost" by going back into the transmitter. There is a control system and a display system associated with the equipment as well. Just as one might expect.
What is the receiver attacker?
A receiver attacker is a type of cybersecurity threat where an attacker intercepts or captures data transmitted between a sender and a receiver. This attack can lead to sensitive information being stolen or manipulated by the attacker. It is important to implement encryption and secure communication protocols to protect against receiver attacks.
Which of the following barriers to oral communication is not the fault of the sender or receiver?
laziness
What does an EMI filter do?
EMI stands for electromagnetic interference. An EMI filter prevents unwanted electromagnetic emissions from being detected by a receiver.
What is the use of radiosonde receiver?
A radiosonde receiver is used to receive data signals transmitted by radiosondes. These devices are typically launched into the atmosphere to collect weather data such as temperature, humidity, and pressure. The radiosonde receiver can capture this data and provide valuable information for weather forecasting and research purposes.
What is the communication and information transfer model?
The transactional model depicts the communication process as one which information is transmitted simultaneously between the sender and receiver.
How did the Receiver obtain wisdom In the giver?
The Receiver obtained wisdom in "The Giver" through memories transmitted by the Giver. By experiencing the pain, joy, and emotions of past generations, the Receiver gains a deeper understanding of the complexities of life and the importance of individual choice and freedom. This knowledge helps the Receiver to see beyond the controlled society they live in and question the status quo.
What the factor to be considered when selecting appropriate media for communication?
-availability -relationship between the transmitter and receiver -reliability of the media -urgency of the message to be communicated -distance between Rx and Tx -nature and status of the receiver- -confidentiality (SECURITY AND SAFETY) -nature of message to be transmitted.
Is GPS and GPRS same or different?
No they are not the same.General Packet Radio Service (GPRS) is for voice communications. Global Position System (GPS) is the use of satellites to determine latitude and longitude which is transmitted to a receiver on earth. It gives you direct location of the receiver, most of the time within feet.
What is a non repeater for communication?
If you are referring to radio transmissions as your form of communication then it's a device that improves or boosts an incoming signal so the receiver can hear what is being said or transmitted.
What are six stage in a two way communication process?
1. The message source generates a message 2. The message source encodes a message 3. the message is transmitted through a medium 4. the message receiver decodes the message 5. the message receiver analyses the messages and puts it in a frame of reference 6. the message receiver reacts with a response or feedback
