A TCP/IP computer cannot communicate with external networks, but it can communicate with the systems on the LAN (as no router is required) if its configuration does not include a default gateway address.

Click the Start button, then choose Command Prompt from the context menu. Step 2: Type "ipconfig" into the Command Prompt window and hit [Enter]. The numbers listed in the Default Gateway section are the IP Address of your router.

30 seconds after unplugging the router, connect it back in. Reconnecting to the internet may take some time. Before continuing, get in touch with your Internet Service Provider if you're still having trouble connecting to the internet.

The information which has been accessed by the attacker running this SQL injection is that: The attacker has determined the names of different types of fields in the database.

In Cybersecurity, SQL injection can be defined as code injection technique which is typically used by an attacker to exploit any web security vulnerability in a database especially by interfering with the queries that are being sent through a software application to the database.

A database can be defined as an organized and structured collection of data that're stored on a computer system as a backup and they're usually accessed electronically.

In this context, we can reasonably infer and logically deduce that this attacker was able to access the names of different types of fields which are stored in the online travel portal's database.

The TCP transmit buffer is not cleaned if an ACK is lacking. This makes perfect sense given that the stack could need to relay the data again.

The next block of data cannot be put into the stack until an ACK is received if the amount of data in the TCP transmit buffer is larger than half the buffer size. The sender resends the same packet if the ACK does not get there before the timeout. Go-Back-N In the ARQ protocol, the sender constantly sends a certain number of packets (defined by the size of the transmission window) without waiting for the receiver to respond with an ACK signal. TCP has the ability to retransmit lost packets. The second transmission reconstructs the data stream by picking up dropped packets.
