SITE-TO-SITE BACKUP: backup, over
the internet, to an offsite location under the
user’s control. Similar to remote backup except
that the owner of the data maintains control of
the storage location.
SYNTHETIC BACKUP: a term used by
NetBackup for a restorable backup image that
is synthesized on the backup server from a
previous full backup and all the incremental
backups since then. It is equivalent to what a
full backup would be if it were taken at the time
of the last incremental backup.
TAPE LIBRARY: a storage device which
contains tape drives, slots to hold tape
cartridges, a barcode reader to identify tape
cartridges and an automated method for
physically moving tapes within the device.
These devices can store immense amounts of
data.
TRUE IMAGE RESTORE: a term used
by NetBackup and Backup Exec for the
collection of file deletion and file movement
records so that an accurate restore can be
performed. For instance, consider a system that
has a directory with 5 documents in it on Friday.
On Saturday, the system gets a full backup that
includes those 5 documents. On Monday, the
owner of those documents deletes 2 of them
and updates 1 of the 3 remaining. That updated
document gets backed up as part of The
Monday night incremental backup. On Tuesday
afternoon the system crashes. If we perform a
normal restore of the full backup from Saturday
and the incremental backup from Monday to
the fresh system, we will have restored the 2
documents that were intentionally deleted. True
image restore keeps track of the deletions with
each incremental backup and prevents the
deleted files from being inappropriately restored.
TRUSTED PAPER KEY: a machinereadable
print of a cryptographic key.
VIRTUAL TAPE LIBRARY (VTL):
a storage device that appears to be a tape library
to backup software, but actually stores data by
some other means. A VTL can be configured as
a temporary storage location before data is
actually sent to real tapes or it can be the final
storage location itself.
ATOM: Another popular feed format
developed as an alternative to RSS.
AUTOCASTING: Automated form of
podcasting that allows bloggers and blog
readers to generate audio versions of text blogs

podcasting)
BLEG: An entry in a blog requesting
information or contributions.
BLOG CARNIVAL: A blog article that
contains links to other articles covering a
specific topic. Most blog carnivals arehosted
by a rotating list of frequent contributors to the
carnival, and serve to both generate new posts
by contributors and highlight new bloggers
posting matter in that subject area.
BLOG CLIENT: (weblog client) is software
to manage (post, edit) blogs from operating
system with no need to launch a web browser.

Management System specifically designed for
creating and maintaining weblogs. The BOBs:
The largest international blog awards.
COLLABORATIVE BLOG: A blog
(usually focused on a single issue or political
stripe) on which multiple users enjoy posting
permission. Also known as group blog.
RETENTION TIME: the amount of time
in which a given set of data will remain available
for restore. Some backup products rely on daily
copies of data and measure retention in terms
of days. Others retain a number of copies of
data changes regardless of the amount of time.
COMMENT SPAM: Like e-mail spam.
Robot ¯spambots flood a blog with advertising
in the form of bogus comments. A serious
problem that requires bloggers and blog
platforms to have tools to exclude some users
or ban some addresses in comments.
DESKTOP BLOGGING CLIENT:
An off-line blog management (posting, editing
and archiving) tool Fisking: To rebut a blog entry
in a line-by-line fashion.

broadcasting (but not for iPods only). Posting
audio and video material on a blog and its RSS
feed, for digital players.
POST: An entry written and published to a
blog. Post Slug: For blogs with common
language URLs, the post slug is the portion of
the URL that represents the post. Example: http:/
/domain.com/2008/01/this-is-the-post-slug
RSS: Really Simple Syndication is a family of
Web feed formats used to publish frequently
updated content such as blog entries, news
headlines or podcasts.
RSS AGGREGATOR: Software or online
service allowing a blogger to read an RSS feed,
especially the latest posts on their favourite
blogs. Also called a reader, or feedreader.

and shows at once when a blog has been
updated. It may contain only the title of the post,
the title plus the first few lines of a post, or the
entire post.
SPAM BLOG: A blog which is composed
of spam. A Spam blog or “any blog whose
creator doesn’t add any written value.”
SLASHDOT EFFECT: The Slashdot
effect can hit blogs or other website, and is
caused by a major website (usually Slashdot,
but also Digg, Metafilter, Boing Boing,
Instapundit and others) sending huge amounts
of temporary traffic that often slow down the
server.
SUBSCRIBE: The term used when a blogs
feed is added to a feed reader like Bloglines or
Google. Some blogging platforms have internal
subscriptions, this allows readers to receive
notification when there are new posts in a blog.
SEARCH ENGINE FRIENDLY
URLS: or, for short, SEF URLs, implemented
with a Rewrite engine.
TRACKBACK: A system that allows a
blogger to see who has seen the original post
and has written another entry concerning it. The
system works by sending a ‘ping’ between the
blogs, and therefore providing the alert.
TEMPLATES: Templates, used on the
“back end” of a blog that work together to handle
information and present it on a blog.
THEME: CSS based code that when applied
to the templates will result in visual element
changes to the blog. The theme, as a whole, is
also referred to as a blog design.
VLOG: A video blog; a vlogger is a video
blogger (e.g. someone who records himself
interviewing people of a certain field). Warblog:
a blog devoted mostly or wholly to covering
news events concerning an ongoing war.
Weblog: the unshortened version of ‘blog’.
OPERATING SYSTEM: An operating
system (OS) is software, consisting of programs
and data, that runs on computers and manages
the computer hardware and provides common
services for efficient execution of various
application software. For hardware functions
such as input and output and memory allocation,
the operating system acts as an intermediary
between application programs and the computer
hardware. Examples of popular modern
operating systems for personal computers are
Microsoft Windows, Mac OS X, and Linux.
MICROSOFT WINDOWS: Windows 7,
is the newest release of Windows. Microsoft
Windows is a family of proprietary operating
systems most commonly used on personal
computers. It is the most common family of
operating systems for the personal computer,
with about 90% of the market share. Currently,
the most widely used version of the Windows
family is Windows XP, released on October 25,
2001. The newest version is Windows 7 for
personal computers and Windows Server 2008
R2 for servers. It originated in 1981 as an addon
to the older MS-DOS operating system for
the IBM PC.
UNIX AND UNIX-LIKE
OPERATING SYSTEMS:
Ken Thompson wrote B, mainly based on BCPL,
which he used to write Unix, based on his
experience in the MULTICS project. B was
replaced by C, and Unix developed into a large,
complex family of inter-related operating
systems which have been influential in every
modern operating system (see History). The
Unix-like family is a diverse group of operating
systems, with several major sub-categories
including System V, BSD, and GNU/Linux. The
name “UNIX” is a trademark of The Open Group
which licenses it for use with any operating
system that has been shown to conform to their
definitions. “Unix-like” is commonly used to refer
to the large set of operating systems which
resemble the original Unix. Unix-like systems run
on a wide variety of machine architectures. They
are used heavily for servers in business, as well
as workstations in academic and engineering
environments. Free Unix variants, such as GNU/
Linux and BSD, are popular in these areas.
Mac OS X: Mac OS X is a line of partially
proprietary graphical operating systems
developed, marketed, and sold by Apple Inc.,
the latest of which is pre-loaded on all currently
shipping Macintosh computers. The operating
system was first released in 1999 as Mac OS X
Server 1.0, with a desktop-oriented version
(Mac OS X v10.0) following in March 2001.
Since then, six more distinct “client” and
“server” editions of Mac OS X have been
released, the most recent being Mac OS X v10.6,
which was first made available on August 28,
2009. Releases of Mac OS X are named after big
cats; the current version of Mac OS X is “Snow
Leopard”.
LINUX AND GNU: Linux is the generic
name for a UNIX-like operating system that can
be used on a wide range of devices from
supercomputers to wristwatches. The Linux
kernel is released under an open source license,
so anyone can read and modify its code. It has
been modified to run on a large variety of
electronics. Although estimates suggest it is
used on only 0.5-2% of all personal computers
it has been widely adopted for use in servers
and embedded systems (such as cell phones).
Linux has superseded Unix in most places and
is used on the 10 most powerful supercomputers
in the world. The GNU project is a mass
collaboration of programmers who seek to create
a completely free and open operating system
that was similar to Unix but with completely
original code.
GOOGLE CHROME OS: Chrome is an
operating system based on the Linux kernel and
designed by Google. Chrome targets computer
users that spend most of their time on the
Internet—it is technically only a web browser
with no other applications, and relies on Internet
applications used in the web browser to
accomplish tasks such as word processing and
media viewing.
INTERRUPT: Interrupts are central to
operating systems, as they provide an efficient
way for the operating system to interact with
and react to its environment.
USER INTERFACE: Every computer that
receives some sort of human input needs a user
interface, which allows a person to interact with
the computer. While devices like keyboards,
mice and touchscreens make up the hardware
end of this task, the user interface makes up the
software for it. The two most common forms of
a user interface have historically been the
Command-line interface, where computer
commands are typed out line-by-line, and the
Graphical user interface, where a visual
environment (most commonly with windows,
buttons, and icons) is present.
KERNEL: A kernel connects the application
software to the hardware of a computer. With
the aid of the firmware and device drivers, the
operating system provides the most basic level
of control over all of the computer’s hardware
devices. It manages memory access for programs
in the RAM, it determines which programs get
access to which hardware resources, it sets up
or resets the CPU’s operating states for optimal
operation at all times, and it organizes the data
for long-term non-volatile storage with file
systems on such media as disks, tapes, flash
memory, etc.
VIRTUAL MEMORY: Many operating
systems can “trick” programs into using memory
scattered around the hard disk and RAM as if it
is one continuous chunk of memory called
virtual memory.The use of virtual memory
addressing (such as paging or segmentation)
means that the kernel can choose what memory
each program may use at any given time,
allowing the operating system to use the same
memory locations for multiple tasks. If a
program tries to access memory that isn’t in its
current range of accessible memory, but
nonetheless has been allocated to it, the kernel
will be interrupted in the same way as it would if
the program were to exceed its allocated memory.
(See section on memory management.) Under
UNIX this kind of interrupt is referred to as a
page fault.
MULTITASKING: Multitasking refers to
the running of multiple independent computer
programs on the same computer; giving the
appearance that it is performing the tasks at the
same time. Since most computers can do at most
one or two things at one time, this is generally
done via time-sharing, which means that each
program uses a share of the computer’s time to
execute.
DEVICE DRIVERS: A device driver is a
specific type of computer software developed
to allow interaction with hardware devices.
Typically this constitutes an interface for
communicating with the device, through the
specific computer bus or communications
subsystem that the hardware is connected to,
providing commands to and/or receiving data
from the device, and on the other end, the
requisite interfaces to the operating system and
software applications.
NETWORKING: Currently most operating
systems support a variety of networking
protocols, hardware, and applications for using
them. This means that computers running
dissimilar operating systems can participate in
a common network for sharing resources such
as computing, files, printers, and scanners using
either wired or wireless connections. Networks
can essentially allow a computer’s operating
system to access the resources of a remote
computer to support the same functions as it
could if those resources were connected directly
to the local computer. This includes everything
from simple communication, to using networked
file systems or even sharing another computer’s
graphics or sound hardware. Some network
services allow the resources of a computer to
be accessed transparently, such as SSH which
allows networked users direct access to a
computer’s command line interface.
REAL-TIME OPERATING
SYSTEM: A real-time operating system
(RTOS) is a multitasking operating system
intended for applications with fixed deadlines
(real-time computing). Such applications include
some small embedded systems, automobile
engine controllers, industrial robots, spacecraft,
industrial control, and some large-scale
computing systems.
.NET: The domain name net is a generic toplevel
domain (gTLD) used in the Domain Name
System of the Internet. The name is derived from
network, indicating its originally intended
purpose for organizations involved in
networking technologies, such as Internet
service providers and other infrastructure
companies. However, restrictions were never
enforced and the domain is a general purpose
name space. It is still popular with network
operators, and is often treated as an alternate to
com. net is one of the original top-level domains
(the other five being com, edu, gov, mil, and
org). As of 2009, it is the fourth most popular
top-level domain, after com, cn, and de.
