A dial-up access connection supports a speed up to <u>5</u><u>6kbps</u>, whereas an ISDN line goes up to 1.9Mbps. A DSL connection can support a maximum of 20<u>mbps</u>. Internet access speed through cable TV is capable of up to 1000mbps.
Dial-up connection is by far the slowest of all known internet connections. The maximum speeds that can be supported by this connection are about 56Kbps. Use of this type of connection requires a separate phone line. In an ISDN type of connection, the maximum speeds depend on where in the world you are. The highest to have ever been recorded is an ISDN E1 line that has a combined data rate of 1.9 Mbit/s. Speeds transmitted through DSL are generally the same ones that are transmitted through cable internet and satellite connection. You can expect DSL speeds of 512Kbps to a max of 20Mbps. The cable internet is a broadband internet access and the highest bit rates of cable internet can go be up to 1GBPS which is equivalent to 1000Mbps.

The explanation of the query is as follows:
select ----> This implies that data is to be selected from the table
sum(stock) ----> This adds up entries in stock column
as total_stock ---> This represents the alias used for sum(stock)column where
from products ----> The table being queried
Take for instance, the content of the table is:
