The firewall present a barrier between measured and secured internal networks that can be trusted and untrusted outside networks, for example the Internet. A firewall can be software, hardware, or even both.

Database tuning helps to optimize the use of machine resources in order to carry out work as efficiently and quickly as possible.
Many systems are built to handle their use of system resources, but there is still plenty of space for enhancing their performance by tailoring their server and DBMS settings and configuration.

Doubly linked chain
When a linked chain contains nodes that reference both the next node and the previous node, it is called a doubly linked chain. This type of chain is often used in data structures because it provides a way to easily traverse the data in both directions. However, because each node must reference both the next node and the previous node, doubly linked chains require more memory than singly linked chains.
