He is not paying an attention to the amount of bits and bytes are being sent over the connection. B and i are only one byte and strong is six bytes.

SQLite is very careful about measuring its memory usage and provides an API to access those measurements.  But in order to measure its own memory usage accurately, it adds 8 bytes to every allocation request in order to store the requested size at the start of the resulting heap block.  In doing so, it converts a lot of 1,024 byte requests into 1,032 byte requests.  Ironically enough, the slop caused by storing the requested size rendered the stored size inaccurate. 

Bandwidth is how much data you can transfer at once (number of parallel cars in the road). Latency is how fast a byte of data will travel end to end (length of the road and speed of the cars).

Round-trip time (RTT) is the time it takes for a client to send a request and the server to send a response over the network, not including the time required for data transfer. That is, it includes the back-and-forth time on the wire, but excludes the time to fully download the transferred bytes (and is therefore unrelated to bandwidth). For example, for a browser to initiate a first-time connection with a web server, it must incur a minimum of 3 RTTs: 1 RTT for DNS name resolution; 1 RTT for TCP connection setup; and 1 RTT for the HTTP request and first byte of the HTTP response. Many web pages require dozens of RTTs.
