Write short note on code optimization.
Code optimization: It is the optional phase designed to enhance the intermediate code therefore the Ultimate object program runs quicker or takes less space. It in compilers aims at enhancing the execution efficiency of a program through eliminating redundancies and through rearranging the computations into the program without influencing the real meaning of the program.
Scope - Very first optimization seeks to enhance a program rather than the algorithm utilized in the program. Therefore replacement of algorithm through a more efficient algorithm is beyond the scope of optimization. As well efficient code generation for an exact target machine also lies outside its scope.
The structure of program and the way in that data is defined and used in this provide vital clues for optimization.
Rule in a single direction - equivalences rules: Hence there the power to replace sub expressions always allows use to prove theorems with equivalences: as given in the above
What is a recursively enumerable language? The languages that is accepted by TM is said to be recursively enumerable (r. e) languages. Enumerable means that the stri
What is a parallel port? A parallel port transfers data in the form a number of bits, typically 8 to 16, concurrently to or from the device.
Full form of is DHCP: Dynamic Host Control Protocol. It is mainly used to bound MAC Addresses of system. Especially for Wireless System.

Q. Explain about Workstations? The workstations are used for engineering applications like CAD/CAM or other types of applications which need a moderate computing power and rela
Some of the uses of append query are as follows ? You will save time by appending data to an existing table rather than manual update. ? Appending files based on particular
Q. Describe the Limitation of FAT16? DOS designers decided to use clusters with as a minimum four sectors in them (so a cluster size of at least 2KB) for all FAT16 hard disks.
Implement the following function using a 3 line to 8 line decoder. S (A,B,C) = ∑ m(1,2,4,7) C (A,B,C) = ∑ m ( 3,5,6,7) Ans. Given function S (A,B,C) = m (1,2,4,7)
