LATEST UPDATE /GRADED A+ /
GUARANTEED PASS!!
3 States a Process Can Be In
- answers-Running (actually using CPU), Ready (runnable, temporarily stopped to let
another process run), Blocked (unable to run until some event happens)
4 Resource Categories
- answers-Process Mgmt
Memory Mgmt
Device Mgmt
Information Mgmt
Absolute Pathname
- answers-Consists of a list of directories that must be traversed from the root to get to
the file with slashes separating the components. /Faculty/Prof.Brown/Courses/CS101
Address Space
- answers-Processes have a list of memory locations from 0 to some maximum which
the process can read or write. It contains the executable program, the program data,
and its stack.
Batch System Goals
- answers-Fairness, Throughput, Turnaround
Binary Semaphores
- answers-Semaphores that can only take two values, usually 0 or 1.
BIOS (Basic Input Output System)
- answers-Known as the "parentboard", a PC contains this: low level I/O software
including procedures to read the keyboard, write to the screen, and do disk I/O among
other things.
Buses
- answers-A communication system that transfers data between computers.
, Busy Waiting
- answers-A type of input and output where a user program issues a system call, kernel
translates into a procedure to the driver, driver starts IO, and sits in a loop to see when
device is done. When IO is complete the driver puts data where needed and returns.
The OS then returns control to the caller.
CMOS
- answers-Volatile memory, used to hold current time and date. It can also hold
configuration parameters, such as which disk to boot from.
Contiguous Block Allocation
- answers-External fragmentation although some blocks may not be fully utilized.
Cores
- answers-Chips that have multiple processors inside them.
Counting Semaphores
- answers-Semaphores that can take on any integer values, some can be restricted to
unsigned.
CPU (Processors)
- answers-The brain of the computer. It fetches instructions from memory and executes
them.
Cylinder
- answers-All the tracks for a given arm position form this.
Daemons
- answers-Processes that stay in the background to handle some activity such as email,
web pages, news, printing, and so on are called these...
Data
- answers-Contains heap and global data structures
Data Segment
- answers-One of the three run time segments. Consists of the variables. Grows upward
Directory
- answers-A way of grouping files together.
Directory that Uses iNodes...
- answers-Each directory entry has the file name in the entry or is in the heap and
pointed at from the directory entry and there is an iNumber to the iNode.
Disk
- answers-Consists of one or more metal platters that rotate at 5400, 7200, 10,800 RPM
