2. DIFFERENCE BETWEEN CRACK AND KEYGEN GO TO INDEX
1. Crack is a Unix password cracking program; Keygen is a generator
program used to ascertain software keys.
2. Crack’s newest permutations have included updates such as a
programmable dictionary generator, and a network distributed password

1. The languages included in Flex are Action Script and MXML, whereas
AJAX includes HTML,JavaScript and XML.
2. Flex takes more time to learn than AJAX.
3. AJAX is considered for tactical improvements, whereas Flex is
preferred for strategic implementations.
4. Flex is preferred for larger RIAs, whereas AJAX is considered more for
smaller RIA deployments.
5. Flex provides native support to animation, bitmap manipulation and
video and audio streaming, whereas AJAX extends limited support to
them.
6. Rendering HTML within an application is fully supported by AJAX, but
Flex provides it with very limited support.

8. DIFFERENCE BETWEEN SQL AND PL/SQL GO TO INDEX
1.SQL is a structured query language used for data manipulation, whereas
PL/SQL is a procedural language to design applications.
2.PL/SQL is an application language usually used to build,format and
display the user screens, web pages and reports, while SQL provides
data for these applications.
3.The user can embed SQL in a PL/SQL program or statement. But the
vice versa is not possible.
4.SQL is slower because it executes one statement at a time, while PL/
SQL executes as a block of code.
5.The core use of SQL is to code queries, data manipulation and
development statements, but PL/SQL is broadly used to code program
blocks, triggers, functions, etc.
