Compiler compiles the whole code and generates the error at
the end whereas interpreter compiles the code line by line
and generates the error immediately.

cachememory is RAM that a computer micro processor(M.P) 
access more quickly than it can access regularly RAM as the 
M.P processes data it looks 1st inthe cache memory and it 
finds the data there, it does not have to do more time 
consuming reading of data from larger memory,cache memory 
is some times described in levels of closeness and 
accessibility to the M.P an L1 cache is on the same chip as 
the M.P

ROM- read only memory
---it can't be modified easily and is used for those data 
which doesn't need frequent updates
RAM- random access memory
--it allows data to be accessed at any order

rom is read only memory...it's having permanent memory 
storage.....
Ram is random access memory...it's having temparary storing 
memory

Linking is the process of combining various pieces of code
and data together to form a single executable that can be
loaded in memory.

Linking can be done at compile time, and also at run time 
Static Loading and Linking
Dynamic Loading & Linking

Linker is a routine or module that links different files 
with eacher if needed, while loader is a program/module 
that loads only program from econdary memory to main 
memeory.

loader means the operating system utility to copies process 
from storage devices to main mermory.
main mermory is also called physical or ram.

Assembler is the step comes in between a sorce code 
and .exe file.the steps are like this Sorce code--
Preprocessor-->compiler(Assemble code)-->Assembler(Object 
Code)-->Libraries linking-->executable files created.
"The assembler creates object code. On a UNIX system you 
may see files with a .o suffix (.OBJ on MSDOS) to indicate 
object code files".

A processor is the logic circuitry that responds to and 
processes the basic instructions that drive a computer. 
The term processor has generally replaced the term central 
processing unit (CPU). The processor in a personal computer 
or embedded in small devices is often called a 
microprocessor. 

A processor is combinational logical Integreted Chip(IC) 
that is designed to perform all operations.When connected 
with in a proper circuitary board.A processor is also know 
as a CPU.It is also called as a microprocessor.

Processor is main system unit of computer., which is process
data electronically.

statements which are accessing shared resourses

In concurrent programming, critical section is a piece of 
code that accesses a shared resource(data structure or 
device) that must not be concurrently accessed by more than 
one thread of execution. A critical section will usually 
terminate in fixed time, and a thread, task or process will 
have to wait for a fixed time to enter it, which is called 
as bounded waiting.
