changes.
Monolithic - correct answer What system is the opposite of a smaller chunked, modular
type of system?
Layered - correct answer What approach uses a modular type of system in multiple
numbers starting from hardware all the way to the user interface?
Microkernels - correct answer What is another approach to a modular type of system
by stripping down non essential components and implementing them as system/user
level programs?
Darwin - correct answer This is the Mac OS X Kernel which is based partly on the
Mach microkernel.
Loadable kernel modules - correct answer This is the best current methodology for OS
design involving a kernel with a set of core components and links, including services via
modules.
Core services - correct answer This provides a layer of a variety of features for Apple's
Cocoa and Aqua systems including support for cloud computing and databases.
,Log file - correct answer If a process fails,, most operating systems write the error
information to this
Core dump - correct answer This is a capture of the memory of the process for later
analysis.
Probes - correct answer Dtrace utilizes providers and consumers of these, and kernel
structures keep track of all of these created.
Profiling - correct answer This periodically samples the instruction pointer to determine
which code is being executed and show statistical trends but not individual activities.
Enabling control blocs - correct answer These are performed when probes fire.
Process - correct answer A program in execution
Text section - correct answer The program code used in a heap can also be called this.
Stack - correct answer All the global variables from the data section and the dynamic
memory called the head all are part of this thing in processes
Passive - correct answer Executable files are stored in what kind of entity?
New, Running, Waiting, Ready, Terminated - correct answer What are the states in a
Process Control Block?
Process state, Program counter, CPU Register, CPU-scheduling information, Memory-
management information - correct answer What are all the components of the process
control block?
,Thread - correct answer A current task being worked on
Process scheduler - correct answer Selects an available process for program
execution on the CPU
ready queue - correct answer A linked list is used to store processes from the job
queue waiting to be dispatched called this
device queue - correct answer If a device is waiting for a particular I/O device, it is
called this
mass storage device - correct answer The long-term schedule pulls from this in order
to load a process
short-term scheduler - correct answer This pulls from the CPU schedule from among
the processes that are ready to execute and allocates the CPU to one of them
IO-bound process - correct answer If a process is doing more I/O than computation,
than it is called this
swapping - correct answer The medium term scheduler removed a process from
memory and then reintroduces the process when needed is called
context - correct answer A processes state is saved and restored by switching this
during interrupts. This is also known as the register set, stacks, and private storage
area.
pid or process identifier - correct answer Most operating systems identify processes
according to a unique integer number called a
, cascading termination - correct answer Zombie processes and orphans are normally
not a problem if this operates properly, because it removes the parents and children in
one batch
bounded buffer - correct answer If there is a limit on the producers and consumers in
the shared-memory systems, it would be considered this
Direct communication - correct answer Each process that wants to communicate and
needs to explicitly name the recipient and/or sender of communication will be using this
nonblocking - correct answer If message passing using the matchmaker / rendezvous
is asynchronous, then the process is
connection ports, communication ports - correct answer Windows uses these two
kinds of ports in their advanced local procedure calls (ALPCs)
Section object - correct answer Larger messages being sent between the two windows
ports must use this region of shared memory called this
socket - correct answer This is a an endpoint for communication, which is not a port,
because a port is just a number
write-end pipe - correct answer Even if Windows uses anonymous pipes, every read-
end pipe must have a
responsiveness - correct answer This allows a program to continue running even if
part of it is blocked or is performing a lengthy operation
resource sharing - correct answer Several different threads of activity can be shared
within the same address space
economy - correct answer Threads share the resources of the process they belong to
