Sample Test 2 Flashcards
The processor itself provides only limited support for multiprogramming, and __________ is needed to manage the sharing of the processor and other resources by multiple applications at the same time.
software
“The process was placed in a suspended state by an agent; either itself, a parent process, or the OS, for the purpose of preventing its execution,” is a characteristic of a _________ process.
suspended
A __________ is a unit of activity characterized by the execution of a sequence of instructions, a current state, and an associated set of system resources.
process
We can characterize the behavior of an individual process by listing the sequence of instructions, referred to as a __________, that executes for that process.
trace
It is the principal responsibility of the __________ to control the execution of processes.
OS
When one process spawns another, the spawned process is referred to as the __________ .
child process
__________ involves moving part or all of a process from main memory to disk.
swapping
When a process is in the _________ state it is in secondary memory but is available for execution as soon as it is loaded into main memory.
Ready/Suspend
A process is in the _________ state when it is in main memory and awaiting an event.
Blocked
The OS must maintain __________ tables to manage processes.
process
The collection of program, data, stack, and attributes is referred to as the _________ .
process image
The _________ is the less-privileged mode.
user mode
A _________ is an individual who seizes supervisory control of the system and uses this control to evade auditing and access controls or to suppress audit collection.
clandestine user
A total of _________ process states are recognized by the UNIX SVR4 operating system.
9
The portion of the operating system that selects the next process to run is called the _________ .
dispatcher
The __________ is a layer of software between the applications and the computer hardware that supports applications and utilities.
Operating System (OS)
A process is in the _________ state when it is in secondary memory and awaiting an event.
Blocked/Suspend
Two essential elements of a process are __________ and a set of data associated with that code.
program code
The _________ tables provide information about the existence of files, their location on secondary memory, their current status, and other attributes.
file
A significant point about the __________ is that it contains sufficient information so that it is possible to interrupt a running process and later resume execution as if the interruption had not occurred.
process control block
A __________ is a legitimate user who accesses data, programs, or resources for which such access is not authorized, or who is authorized for such access but misuses his or her privileges.
misfeasor
When the OS creates a process at the explicit request of another process, the action is referred to as __________ .
process spawning
The process is said to be operating in a _________ fashion if each process in the queue is given a certain amount of time, in turn, to execute and then returned to the queue, unless blocked.
round-robin
A process in the _________ state is in main memory and available for execution.
Ready
_________ tables are used to keep track of both main (real) and secondary (virtual) memory.
Memory
The process control block information can be grouped into three general categories: process identification, __________ and process control information.
processor state information
A __________ is the maximum amount of time that a process can execute before being interrupted.
time slice
System access threats fall into two general categories: __________ and malicious software.
intruders
A _________ is an individual who is not authorized to use the computer and who penetrates a system’s access controls to exploit a legitimate user’s account.
masquerader
An IDS comprises three logical components: sensors, __________, and user interface.
analyzers
