Answer / sivakumar s
Address Space: Range of virtual memory assigned for user or
seperately running program.
Swapping: Transferring all of the pages of an Address Space
between Real & Auxiliary Storage.
SWAP-IN: Swapping from Auxiliary to Real.
SWAP-OUT: Swapping from Real to Auxiliary.
Address Space size: Basically the size of the address space
depends on the number of bits used by the OS. So, size of
16 bits address space is (2 to the power of 16) 64KB.

Answer / pratap kumar panigrahi
As far i know Swap-in and Swap-out is the transfer of the
whole content from main memory to virtual memory and vice-
versa.
Address space is nothing but the rsnge of address.
Size of address space in 16 bit address space is 32KB.

Answer / asik
When set of paged data sets moved from auxillary storage to
real storage during execution of any job is called swap-in.
Reverse is swap out.
Allocation of virtual storage (mostly) or real storage space
that has pointer or addresses for the location of actual
data for any subsystem is address space in MVS.
Size of address space for 16 bit is 2 to the power 16 = 64KB

Answer / s.seenivasan
All hav already given defn for swap in swap out and for
address space too....
formula for address space = 2^(n-1)
therefore, for 16bit, 2^(16-1)=2^15=2^5 x 2^10 = 32 KB.

sorry buddies...
i made mistake while specifing the title.dats y i modified
here....
swap-out:
block of frames(pages) are moving from real to dataset
called sys1.swap(Aux). this ill happen when we have no free
frame's in
real memory .
swap-in : vice-versa...

Answer / ram
Swapping: Transfer the recent valid private address spaces between real storage and auxilary storage.it is not possible in real mode.
swap in :from auxilary storage and real storage.
swap out :from real storage and auxilary storage.
Address space: it is the complete range of address.i.e., reffered to an application space , in which only programs can execute and it contains no data.
formula =(2^n)-1
=(2^16)-1
=65536-1
=65535~64kb.

swap out : vice-versa...
address space(AS):
address space, after 1970's our ibm came out with address
space concepts.. each byte of address space can
addrressable and every AS has common area and accessed by
other AS called as MRO. we can call it as virtual storage
it resides in aux,.storage . ..
size of AS : 0-2GB.(2048mb)
What is the size of the address space in KBs for 16 bit
address space?
((2)^16)-1...
so 2^16=65536-1=65535(64kb)
