Bridge:
Bridge is a network device which works in data link layer. Bridge connects two different LAN working on same protocol. Also In bridge, format of packet is not changed.

Gateway:
Gateway works in OSI model’s all layer. It converts the protocol. Gateway will settle for and transfer the packet across networks employing a completely different protocol. In gateway, format of packet is changed which oppose to the bridge.

<th>ASIS FOR COMPARISON</th> <th>BRIDGE</th> <th>GATEWAY</th>

Basic	Bridge transmits the frames between two separated segments of LAN.	Gateway is a protocol converter.
Layer of Operation	Operates on two layers, physical and data link layer.	Operates on all the seven layer of OSI model.
Work	Checks the destination address on received frame and forward the frame to the address it belongs.	It allows two different network using different protocols to communicate with each other.

Arrange rows by column values. arrange() order the rows of a data frame rows by the values of selected columns. To sort by one column, you can use the SORT function or SORTBY function. In the example shown, data is sorted by the Group column. The formula in F5 is: =SORT(B5:D14,3) Notice data is sorted in ascending order (A-Z). group_by() is a great function for aggregation in the “dplyr” package. It's one of the five main “verbs” of the package along with select(), filter(), arrange() and mutate(). If you don't know dplyr well or these functions then go and learn them immediately.
