Answer: True
Explanation:
Yes, the given statement is true that that one of the quality of the wireless networks is that they uses the various radio techniques and the radio frequency.
By using this techniques, the wireless transmission occur and it enable the connectivity and allow the direction of transmission to eavesdrop. It is one of the best technique as compared to the traditional method which include copper and fiber.
Answer:
Yes, is should work
Explanation:
USB is widely adopted and supports both forward and backward compatibility. The USB 3.0 printer should work with the USB 2.0 computer. However, having a connection like this, the printer will only be able to work at the speeds of the computer’s USB 2.0. By default, USB is built to allow transfer speeds improvement with upgrades from previous generations while still maintaining compatibility between devices that are supported by them.
True; synchronous means existing or occurring at the same time (I really don't know if that's a question but oh well)
Answer:
A
Explanation:
The internet protocols are changed every year to adapt to the new devices that have been connected to the network. Back in the 1990s, most traffic used a few protocols. Pv4 routed packets, TCP turned those packets into connections, SSL (later TLS) encrypted those connections, DNS named hosts to connect to, and HTTP was often the application protocol using it all.
For many years, there were negligible changes to these core Internet protocols; HTTP added a few new headers and methods, TLS slowly went through minor revisions, TCP adapted congestion control, and DNS introduced features like DNSSEC. The protocols themselves looked about the same ‘on the wire’ for a very long time (excepting IPv6, which already gets its fair amount of attention in the network operator community.)
As a result, network operators, vendors, and policymakers that want to understand (and sometimes, control) the Internet have adopted a number of practices based upon these protocols’ wire ‘footprint’ — whether intended to debug issues, improve quality of service, or impose policy.
Now, significant changes to the core Internet protocols are underway. While they are intended to be compatible with the Internet at large (since they won’t get adoption otherwise), they might be disruptive to those who have taken liberties with undocumented aspects of protocols or made an assumption that things won’t change.
