Complete Question:
A system has defined specifications that describe how signals are sent over connections. Which layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model provides this function?
Group of answer choices.
A. Transport
B. Network
C. Data link
D. Physical
Answer:
A. Transport
Explanation:
Transmission Control Protocol/Internet Protocol (TCP/IP) model is a standard communication protocol used for interconnecting network devices such as routers, switches, host computers and access points over the internet.
A system has defined specifications that describe how signals are sent over connections. The layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model that provides these functions is the transport layer.
The transport layer comprises of two (2) standard protocols and these are TCP and UDP.
TCP is an acronym for Transmission Control Protocol and it is one of the essential and important protocol of the internet protocol network. This simply means that, it is an essential part of the TCP/IP network. The TCP has a wide range of applications in the following areas, file transfers, world wide web, remote administration, e-mail, etc.
The TCP connection are mainly established in the network using the three-way handshake.
UDP is an acronym for user datagram protocol and it enables the transfer or exchange of data between network devices.
Answer: True
Explanation: In data mining, they use statistics component for the analyzing of the large amount of data and helps to deal with it. Statistics provide the techniques for the analyzing, evaluating and dealing with the data that is known as data mining.Data statistics provide the help to organize large data in a proper form and then analyze it. Thus, the statement given is true that data mining must use statistics to analyse data.
Answer:
RFID scanning or Barcode reader
Explanation
Smart refrigerators have inbuilt RFID scanning technology that help monitor the stock that is inside your fridge. Once you pass your items through the inbuilt RFID scanner in the fridge, the barcode of your items is cross-referenced with a database and given a unique tag for identification. This technology helps detect and track the stock that is inside your fridge and when you start running low, the RFID can be triggered to send a reminder as a notification on your email or a text message.
