Answer: True
Explanation:
Each connection socket is identified with a four‐
tuple: (source IP address, source port number, destination IP address,
destination port number). When host C receives a segment, it
examines the segment and the operating system will provide the process with the IP address.
You can start by looking at the date. Anything made before 1923, no matter what, will be definitely in the public domain. ... Most times, it's impossible to determine whether something is in the public domain just by the date. There are three ways you can find out definitively whether a work is in the public domain.
Answer:
require direct line-of-sight scanning.
Explanation:
Unlike radio frequency identification (RFID) tags, bar codes require direct line-of-sight scanning. Meaning you need a device that can scan the bar code and the scanner needs to be directly pointing at the barcode without anything in the way. This is because bar codes work by embedding the information in a design of lines that need to be scanned to retrieve the information. If anything gets in the way it interrupts the scanning process and the data is not correctly transmitted. RFID tags on the other hand do not need a direct line of sight since the information is transferred through radiofrequency. This allows the data to be transferred without a line of sight and at a distance of up to 300ft.
