Answer:
In centralized method, the authorized sender is known, but the transmission line is dominated by the control station, while in decentralized method, one station can not dominate the line but collision on the transmission line may occur.
Explanation:
Centralized method of communication requires for a control station to manage the activities if other stations in the network. It assigns turns to one known station at a time, for transmission.
Decentralized method allows stations in a network to negotiate and take turns in transmitting data. When a station is done with the transmission line, another station on the queue immediately claims the line.
Answer:
false
Explanation:
it depends most of time so false
Answer:
There are no additional components that can be added to the IPv4 protocol to improve its utility
Explanation:
The IPv4 protocol was developed in 1983 and is still the most widely used version worldwide. It consists of a 32-bit binary number that is normally represented in decimal notation, with four digits separated by dots that take values between 0 and 255.
This system limits the IPv4 protocol to 4,000 million different addresses, a figure that in the eighties seemed sufficient but that in practice has been scarce due to the revolution of mobile devices and the impending development of the Internet of Things ( IoT) that will trigger the number of devices connected to the network.
So, there are no additional components that can be added to the IPv4 protocol to improve its utility, since the world is running out of IPv4 addresses and is being replaced by IPv6.
Hope this helps!
Answer:
-26
Explanation:
The given binary number is 1110 0101. Also given that the signed binary number is represented using one's compliment.
We begin by computing the 1s complement representation of 1110 0101 by inverting the bits: 00011010
Converting 00011010 to decimal, it corresponds to 26.
So the 1s complement of the original number is 26. This means that the original number was -26.
The answer is Ethernet
Ethernet is by far the most popular LAN by a mile. It is a
group of protocols that work at either the Data link layer or the Physical
layer of the OSI model. Ethernet in the engineering world is defined as the
IEEE 802.3 specification.
