Compilers require more memory because they need to store various intermediate representations of the source code, such as abstract syntax trees and symbol tables, which are essential for analyzing and optimizing the code. Additionally, compilers often include multiple phases, such as lexical analysis, parsing, semantic analysis, and code generation, each of which demands its own data structures and memory allocation. Furthermore, optimizations can lead to increased memory usage as the compiler keeps track of additional information to enhance the final output.

Do Macs require different memory than PCs?
Yes they will require different memory than PC's, also being more expensive.
What is the use of compiler in c language?
Compilers check correctness of your program syntax, memory allocation procedures and so on.
Why does a computer require different memory storage?
memory is a store deta is callad memory storage and computer require take deta in memory.
What does maximum address by a poniter refer in TC and GCC compilers?
In turbo C pointer maximum refers up to 1MB of memory, wheras in GCC pointer refers up to 4 gb of memory.
In general do operating systems for desktops and workstations require more or less memory than the operating system for servers?
Generally speaking, servers usually have more memory than desktops and workstations.
What is symbol table and in which part of the memory it is stored?
Symbol table is a file that Compilers / Assemblers use to store symbols and their equivalent relative memory locations, values, data types for the following steps. It's an intermediate file, so the compiler chooses where to store it. Some compilers delete the file after processing
What jobs require good short term memory?
an auctioner, or you can just learn to have longterm memory, lots of jobs require that! ;)
Advantages of interpreters over compilers in systems programming?
during testing of any code it is usefull, normally interpreters are slow as we need to interpret every time the code is to be executed , but for compilers object code generated can used for any no . of times . for a code to be interpreted it has to be completely in main memory .
In general do operating systems for desktops require more or less memory than operating systems for servers?
less
Why you require different operating system for different compiler?
Actually it's the other way around. You require different compilers for different operating systems. The reason for this is that an operating system is basically an intermediate step for a person to be able to interact with the hardware on their system. Each OS has a different way to do this, and so compilers must be different for each one, even for the same language.
Advantages and disadvatages of single and multi pass compiler?
Single pass: Adv: More efficient than multi pass compilers in the compiler phase. Smaller compilers than multi pass Dis: Produces less efficient programs. Multi pass: adv: Can be useful when optimizing code. more machine independent Java like variable declaration - it doesn't need to be before the use of it, because Java require multi pass compilers. Dis: Slower at compile time
