Windows 7 Serials
Sometimes in conjunction
with Keygens, hackers may release serials.
A serial number is a unique number that is one of a series
assigned for identification which varies from its successor
or predecessor by a fixed discrete integer value. Common
usage has expanded the term to refer to any unique
alphanumeric identifier for one of a large set of objects,
however in data processing and allied fields in computer
science. Not every numerical identifier is a serial number;
identifying numbers which are not serial numbers are
sometimes called nominal numbers.
Sequence numbers are almost always non-negative, and
typically start at zero or one.
Serial numbers are valuable in quality control, as once a
defect is found in the production of a particular batch of
product, the serial number will quickly identify which units
are affected. Serial numbers are also used as a deterrent
against theft and counterfeit products in that serial
numbers can be recorded, and stolen or otherwise irregular
goods can be identified.
Many computer programs come with serial numbers, often
called "CD keys," and the installers often require the user
to enter a valid serial number to continue. These numbers
are verified using a certain algorithm to avoid usage of
counterfeit keys.
Serial numbers also help track down counterfeit currency,
because in some countries each banknote has a unique serial
number.
The ISSN or International Standard Serial Number seen on
magazines and other periodicals, an equivalent to the ISBN
applied to books, is serially assigned but takes its name
from the library science use of serial to mean a periodical.
Certificates and Certificate Authorities (CA) are necessary
for widespread use of cryptography. These depend on applying
mathematically rigorous serial numbers and serial number
arithmetic
The term "serial number" is also used in military formations
as an alternative to the expression "service number".
A software license is a license that grants permission to do
things with computer software. The usual goal is to
authorize activities which are prohibited by default by
copyright law, patent law, trademark law and any other
intellectual property right. The reason for the license,
essentially, is that virtually all intellectual property
laws were enacted to encourage disclosure of the
intellectual property.
As software is so easily
replicated, disclosure is not an option that most software
vendors would prefer to avail themselves to. The result is
that the vendors need an alternate method of allowing the
licensed user to use the product but still be restricted so
as to prevent certain reverse engineering rights the user
might otherwise have as a result of the default intellectual
property rights.
Typically, then, the software license is a complex document,
identifying the specific usage rights that are granted to
the licensee, while also stating the license limitations.
For example, a software license might give permission to
allow a certain number of concurrent users of the software.
This means that at any given point in time, a limit exists
on the number of people who can use the software.
As a specific user stops
using the program, then another, different user can start to
use the program. Compare and contrast this with a named user
model, whereby the software is licensed to specific
individuals. Regardless of whether the named individual is
actually using the product or not, another individual is not
licensed to use that same copy of the software.
A software vendor may offer a software license unilaterally
(without giving the licensee the opportunity to negotiate
for more favorable terms), or even as part of a software
license agreement with another party. Virtually all
proprietary software is sold under some form or fashion of
software license agreement, including free software and open
source software which are usually distributed under the
terms of their EULA.
Failure to abide by the terms of the license can subject the
violator to the default penalties for violations of
intellectual property laws in and if so allowed by the
geographic region of the licensor, as well as any
contractually agreed-upon damages listed in the software
license.
