object --
1. An object is a graphical representation of a file.
Each object has two parts: the picture or icon that
appears on the desktop, and action scripts that are invoked
when operations (such as double-clicking and drag and drop)
are performed on the object.
2. For SNMP, an abstract management object with an associated
syntax, access, status, and name (OBJECT IDENTIFIER); a managed
object is a template -- it is the instances of the object
which are actually manipulated by
get,
get-next,
and
set
operations.
object file --
A file of machine language code and data.
Object files are produced from source
programs by compilers and from other object files
and libraries by the link editor.
A relocatable object file contains references to symbols that
have not yet been linked with their definitions.
An executable object file is a linked program.
See also
source file.
Object Reuse --
The reassignment, from one process to another,
of a storage object
(such as a segment of memory, disk block, or magnetic tape)
that contains data owned by
the original owner process.
OctetString --
An
ASN.1
primitive data type, taking zero or more
octets as its value. Each byte in an octet string may take any value in the
range 0 to 255.
ODI --
Open Datalink Interface,
an architecture that allows multiple LAN drivers and
protocols to coexist on network systems.
The ODI specification describes the set of interface
and software modules used to decouple device drivers from protocol stacks
and to enable multiple protocol stacks to share the
network hardware and media transparently.
OID --
An OBJECT IDENTIFIER.
An object syntax type consisting of a sequence of non-negative
integer values that traverses a tree (for example, 1.3.6.1).
The OID denotes an authoritatively named object regardless
of the semantics (for example, a standards document, an
ASN.1
module, and so on) associated with the object.
OK button --
A button in a dialog box that accepts any changes you
made in the box. Click on the OK button with
mouse button 1 to accept your changes.
online --
Accessible from your terminal screen.
online help --
A facility that provides explanatory text if
you need assistance or more information.
onstop event --
(programming)
When using the GUI debugger,
an onstop event specifies an action for the debugger to
perform whenever a process stops for any reason.
The action can be one or more of the commands available
through the debugger's command-line interface.
open --
To display a file or window so you can view or modify its
contents. Use the Desktop to open windows; use a program
to open files.
OpenPDU --
A Protocol Data Unit sent by an SMUX
peer
to an SNMP
agent
to initiate an SMUX association with that agent.
An OpenPDU contains authentication
information (OID-password pair) which the agent
compares to data specified for that peer in the configuration file
/etc/netmgt/snmpd.peers.
operating system --
A group of programs that provide basic functionality on a
computer. These programs operate your computer hardware in
response to commands like copy and
print, and form a set of functional building
blocks upon which other programs depend. An operating
system also manages computer resources, such as peripheral
devices
like disk drives or printers attached to the computer,
and resolves resource conflicts, as when two programs want
to use a disk drive at the same time.
optimizer --
(programming)
An optimizer improves the efficiency of
the assembly language code generated by a compiler.
That, in turn, speeds
the execution time of your object code.
option --
1. An optional keyword specified on the command line, used
to set up some feature of a command. Command-line options
usually consist of a hyphen followed by a single letter.
See also
argument.
2. The choices offered on a menu.
Options invoke a window or another menu and are selected by
typing the first letter of the option name, or by selecting
the option name with the mouse. See also
menu.
orderly release --
(programming)
A procedure for gracefully terminating a transport connection
with no loss of data.
orphaned process group --
(programming)
A process group in which the parent of every member in the group is
either itself a member of the group, or is not a member of the process
group's session.
other --
1. A set of permissions regulating access
to a file by processes with a user ID
different from that of the owner,
and a group ID different from that of the group for that file.
2. The customary name of the default group
assigned upon login.
overlay installation --
A nondestructive installation where one release of the operating
system replaces another version of the same release. This type of installation
is useful when you want to retain user data while replacing potentially
corrupted operating system or application software.
owner --
1. The user who created a file or directory.
Only the owner and root can change the
permissions assigned to the file or directory.
2. One of the attributes of a
file
that, along with its
group
and
permissions,
determine who can access and modify that file. You can see
the owner of a file by using the
ls(1)
command with the -l option. Use the
chown(1)
command to change the owner of a file.
