title: Operating System Process Management, Memory Management, Kernel
body: <p>I am working in software firm where hardware independent coding is done on the Network Chipsets and fully Multigthreading coding implemented and various buffers(CRU Buffer, Linear Buffer) are handled and memory (stack memory) is optimally used. And IPC done via Message queues. And Multiple Locks, Semaphores are used for concurrency mechanisum. Now i will be assigned to new development project, where i have to understand and have to develop new features in next one month. I am feeling like middle of the Amazon Jungle :).</p>
  
  <p>=> I am in beginning level in OS concepts. I feel like intermediate level in C language. So expecting, suggestion for "Materail/Book which could help me to improve/concrete my OS skills"</p>
  
  <p>i saw OS Book by Abraham Silberschatz and Modern Operating Systems by Tanenbaum - 3rd Edition. Both are looking big and covers all corners of operating system. I thought to study that book steadily and slowly for future referencee.</p>
  
  <p>==> Now i am looking for the Network materials/books which explaining the "Main concepts" in the detailed manner. For example i have seen virtual memory concepts in one online material where clearly virtual memory explained.</p>
  
  <p>Example abour virtual memory from that material:</p>
  
  <p>amesmol@aubergine:~/test> objdump -f a.out</p>
  
  <p>a.out: file format elf32-i386 architecture: i386, flags 0x00000112: EXEC_P, HAS_SYMS, D_PAGED start address 0x080482a0</p>
  
  <p>explanation:</p>
  
  <p>Notice the start address of the program is at 0x80482a0.Program thinks like where its starting address is actual physical address. But it is a virtual address space. Its original starting address at physical memory location 0x1000000.</p>
  
  <p>As like this( correct point and example), could you people suggest good materials for the OS concepts ( Process Management, Memory Management, IPC)?
  Can you also suggest the ways to improve/concrete this skills? (suggest either what kind of mini homework project i can do, etc..)</p>
  
  <p>Thanks in advance</p>
