A computer’s capability to process more than one task simultaneously is called multiprocessing. A multiprocessing operating system is capable of running many programs simultaneously, and most modern network operating systems (NOSs) support multiprocessing. These operating systems include Windows NT, 2000, XP, and Unix. This chapter covers multiprocessing with an eye towards passing the CompTIA Server+ Exam.
This chapter is from the book

Terms you’ll need to understand:

  • Multiprocessing
  • Internal register
  • Network operating system (NOS)
  • Loose coupling
  • Tight coupling
  • High-level cache
  • Shared memory
  • Symmetrical multiprocessing (SMP)
  • Asymmetrical multiprocessing (ASMP)
  • Scalable system architecture
  • Coherent system
  • Spinlock mode
  • Microkernel architecture
  • Process programming
  • Multithreading
  • Bus snooping
  • Massively parallel processing (MPP)
  • Overhead
  • Latency
  • Determinism
  • Skew
  • Steppings
  • Bit ratings

Techniques you’ll need to master:

  • Increasing the overall processing power of a single node
  • Allocating resources
  • Increasing the overall processing power of a system
  • Differentiating between level 2 and level 3 cache
  • Using multiple threads
  • Flushing the cache
  • Configuring network operating systems
  • Preventing the system bus from becoming a bottleneck
  • Determining the bit rating of a specified processor
  • Tuning a server network’s performance
