In fundamental, reliable, connection-oriented data transfer, datagrams are delivered to the receiving host in exactly the same sequence they’re transmitted—and the transmission fails if this order is breached! If any data segments are lost, duplicated, or damaged along the way, a failure will transmit. This problem is solved by having the receiving host acknowledge that it has received each and every data segment. , a three-way handshake). It uses sequencing. It uses acknowledgments. It uses flow control.
1 with a switch? Whether you did or didn’t, the reason I did that is because hubs don’t segment a network; they just connect network segments together.

Another example for our nibble values would be 1010, which means that the 8 bit and the 2 bit are turned on, which equals a decimal value of 10. If we have a nibble binary value of 0110, then our decimal value would be 6, because the 4 and 2 bits are turned on. But the byte values can add up to a value that’s significantly higher than 15. This is how: If we counted every bit as a one (1), then the byte binary value would look like this (remember, 8 bits equal a byte): 11111111 We would then count up every bit spot because each is turned on.
