SIM Full Form Name
Full Form of SIM :
Subscriber Identity Module
SIM Full Form is Subscriber
Identity Module. It is basically a smart card found inside cell phones. SIM
carries a unique number specific to the owner and stores data and prevents its
usage when removed from the phone. Nevertheless, unlike the CDMA or Code
Division Multiple Access phones, only Global System for Mobile or GSM type of
phones use SIM cards.
The SIM card comprises of a chip
which is inserted into the phone to initiate usage by tapping into a particular
network. The most important feature of the SIM card, which makes it work, is
the authentication key. The authentication key of a SIM card is given by
the service provider. This has to be activated whenever a new SIM card is used.
It is a huge blessing that allows individuals to change phones without changing
the SIM card.
SIM Full Form – Additional
Information
We all know that when we buy a
mobile phone then to activate it we need a SIM card. Very few are actually
aware what the full form of SIM is or its importance. It is a smart card
or an integrated circuit card (chip) that is used in GSM phones (Global System
of Mobile communication) and besides encrypting data (SMS) and voice
transmission, it stores user identity data that authenticates and identifies
the subscriber on the telephone network circuit.
SIM card, as it is popularly
known, can store user settings pertaining to storage of phone numbers, data
messages, etc. It is identified by a unique code that is engraved on the chip
known as ICCID or Integrated Circuit Card Identifier as well as IMSI or
International Mobile Subscriber Identity. SIM is engraved on a removal and
portable smart card that we know as the SIM card. This has the portability of
being used in different mobiles and yet retaining its unique identity.
The first ever SIM card was
developed in Munich in 1991 by Giesecke & Devrient and the initial 300
cards were sold to a Finnish wireless network operator. Besides the ICCID and
IMSI codes, the SIM has temporary data about the local network and the services
that the user has permission to access. It also has a provision of storing two
passwords – a PIN or personal identification number for regular use and PUK or
personal unblocking code for unlocking the PIN.
What is the importance of SIM
The SIM cards are available in
two variants – mini SIM cards and micro SIM cards. The first type is used in
normal GSM mobiles and the micro-SIM card is inserted to activate a smart
phone. A SIM card can be changed from one handset to another and yet the data
stored on it like your contacts, their numbers and data messages etc remains
intact. This is the major advantage of a SIM card because it gives security of
communication.
In case the mobile handset gets
damaged or the battery runs low, then by just replacing the card from damaged
mobile to another puts you back on track of mobile communication. In the
current world, there are too many crimes and cases of terrorism. The threats
are usually carried out using a mobile phone since you can make the call and
destroy the card. However, since each number is associated with a particular
SIM card, it is easy to trace the owner of the number and thus reach the
culprit.
When a person applies to obtain a
SIM card, that person’s residential proof and photo identity are collected for
verification. Only after satisfactory verification of the user, the network
provider opens the service for that number. This ensures that there is no
misuse of the SIM. However, the clever criminal minds find loopholes in the
system and collect many SIM cards for nefarious use. Nonetheless, since SIM is
unique in its character, there is nothing much that can be done in terms of
cheating and finally the card gets detected on the network.
Various features of SIM card
This is a modern age when
everything can be obtained in multiple numbers. Similarly, as far as SIM card
usage is concerned per person, there is no need to have just one. Presently,
many GSM as well as smart phones have a facility of inserting two SIM cards and
are known as “dual-SIM phones”. This is particularly practical for businessmen
etc who can then take the privilege of keeping the two identities separate. One
SIM card can be used to store personal numbers and messages; whereas the other
card can be exclusive for business purposes. This gives a scope for privacy and
organization of contacts as per personal and business grouping.
These dual SIM cards can be
operated in two ways. In some phones, the cards need to be switched to use and
the other type of phones especially smart phones have the facility to keep both
the SIMs active at the same time. Even though currently the mini and micro SIM
cards are widely used, there is a third type that is the size of a credit card.
But it is not in use any more. The micro-SIM was designed with compatibility in
mind. The same phone should have the facility of mini as well as micro card and
thus the contact area of reading the card data is kept the same. In some cases,
instead of buying a separate micro SIM, people cut their mini cards with a
Knife or scissors to the micro size.
SIM and network providers
The SIM card opened a whole
avenue of business for different network service providers. The providers need
not possess or run a cellular telecom network. It is a leased capacity from the
actual network owner and these are just mobile virtual network operators (MVNO)
who provide a SIM with their network to the customer.
In today’s age, there is a
competition between service providers and though initially it was not possible,
now it is possible to change your service provider with the same telephone
number that has been assigned to you. This is called “number portability”. So
in case you are not satisfied with the transmission, connectivity or services
of your network service provider, you can opt for a better carrier.
Even though in India it is not
prevalent as far as the use of GSM phones are concerned, but in some countries
like USA, UK, Canada, Australia etc there is a system of the mobile phone being
locked to a particular service provider and the SIM card is not accepted of any
other carrier. However, some providers do give the option of unlocking the
phone and then the customer has the liberty to use which ever SIM card he
likes.
How a SIM works
A unique code IMSI (International
Mobile Subscriber Identity) identifies the SIM card on the carrier’s networks.
Each SIM card is tied to its location and if the phone is carried to different
state, then it goes on a roaming network, where the base service provider has
tie –up with other networks with good transmission signal in the area. Since
these are external leased lines, the charges for calls made on roaming network
are always more. Each SIM has a personalized authentication key known as K¡
provided by the operator. The same key is also stored in the database of the operator’s
network. This database is known as Authentication Center or AuC.
When the mobile handset is
started, it gets the IMSI from the SIM card. This is then passed on to the
carrier to request right of entry and authentication on the network. Then through
series of processes the operator matches the K¡ with the database number and if
the two numbers match, the customer is granted access to the operator’s
network. Talking on a mobile phone may seem like an easy task. Nonetheless, the
whole process of getting a connection for communication through a small chip
called the SIM card is surely a complicated mission.
SIM Full Form: Singapore
Institute of Management
Full Form of SIM refers to Singapore
Institute of Management. Also known by its abbreviated form SIM, It is the
largest institute in Singapore in respect of private education and professional
training. The institute, or let us just simply refer to it as SIM, was
established in the year 1964 by the Singapore Economic Development Board.
Also known as EDB, the Singapore
Economic Development Board is a statutory body that creates framework to ensure
the development of business and investment avenues in the country. The SIM is
located in Clementi, Singapore. Under the aegis of the SIM, Singapore’s first
privately funded institute the SIM university was established in the year 2005.
The Ministry of Education has
approved a number of degree courses that the SIM University provides. Because
of the extensive course structure and national status, the university is
popular and has an enrollment of about 10.000 students admitted in different
disciplines. In the year 2008, the SIM had initiated the process to make UniSIM
programs more accessible to adult learners. Permanent residents who enroll in
the UniSIM’s programs are eligible for a government subsidy of 20% of tuition
fees and eligible Singaporeans get 40% subsidy.
The SIM offers degree courses in
a variety of disciplines and conducts about 50 educational programs in
different countries like the United States, the United Kingdom, Europe and
Australia. Apart from full-time courses, the SIM also offers part-time courses
and diplomas. The SIM offers undergraduate degrees like Bachelor of
Communication, Bachelor of Arts Economics, Bachelor of Science in Marketing, and
the Bachelor of Science in Economics.
As far as master courses are
concerned, the university offers such degrees on Science in Digital Marketing,
Science in Engineering Business, etc. Most of these degrees are awarded by
foreign universities like the Bachelor of Communication is awarded by RMIT
University, the Bachelor of Arts Economics is awarded by the University of
Buffalo, the Master of Science in Digital Marketing is awarded by the
University of Southampton, etc.
The SIM has four campuses and
this fact makes it Singapore’s most extensive privately funded institute. The
SIM headquarters is the center for all student activities and events. There is
SIM Management House that undertakes membership and workshop activities. The
administrative functions are conducted in the SIM Clementi Centre. The SIM
provides SIM Global Education @Ulu Pandan, which is one of the largest
facilities that provide boarding facilities, seminar hall, etc.
Full Form of SIM: Security
Information Management
SIM Full Form stands for Security
Information Management. SIM refers to a terminology often used in
Information Security field. The term is used to allude to a collection of data,
which includes log files. The collected data is moved into a central repository
that undertakes thorough trend analysis. Thus, it does what the name sounds: it
manages the data collected and performs security analysis.
Products with Security
Information Management, or let us just refer to it as SIM, behave like software
agents that operate on computer systems, which need to be analyzed. These
agents then transfer the log information to a server that functions as a
centralized system or “security console”. This “security console” is an
important system to begin with: it generally displays reports, charts, graphs,
etc of the information it has received. In fact, there are some software agents
that make use local filters with the purpose of lowering down and manipulation
of data that they eventually transfer to the “security console”. The “security
console” is handled by a human being, who is tasked with the duty of reviewing
the information by undertaking analysis and report alerts, if any.
A security console is necessary
because it performs the primary task of correlation and analysis and the
information sent to the console are normalized by the software agents into a
commonly used form, which is generally XML (Extensible Markup Language). Often
the use of terminology SIM is mistaken to mean a reference to the feature of
protection of one’s infrastructure from any potential security breach. It is to
be understood that SIM refers to a mechanism that unearth irregular behavior of
the computer system with the help of techniques pertaining to data collection.
Thus, it would be wrong to
understand the functioning of the SIM to be similar to that of Information
Security Management (InfoSec), which is a terminology used in reference to the
complete security mechanism that protects the computer environment. Apart from
being referred to as SIM, the Security Information Management is often referred
to as log management, which is totally different from Security Event Management
(SEM). SIM is however a part of Security Information and Event Management
(SIEM).
SIM Full Form: Society for
Information Management
Full Form of SIM refers to
Society for Information Management. SIM is one of the most prominent and
preferred professional organization in the world, with 4,500 senior information
technology (IT) executives, Chief Information Officers, academicians, and other
IT think tanks. The organization endeavors to help in enhancing intellectual
capital by bringing together IT intellectuals.
Let us explore some historical
facts concerning the inception and developments surrounding the SIM. At the
Association for Computing Machinery (ACM) conference held in Las Vegas in
August 1968, the establishment of SIM was conceptualized.
This happened when a conversation
was initiated between Robert Head with the Software Resource Group and Herb
Schwartz with the United States Atomic Energy Commission. They discussed how
inappropriate and insufficient emphasis upon the management aspects of
computing. This discussion went on to become the foundational principle of the
SIM that came into being in the year 1982. Many stages of discussions and decision-making
led to SIM.
A committee was instituted in the
year 1968 that held its first meeting at the United States Atomic Energy
Commission in the same year. Joseph P. Cunningham, Richard E. Dooley, Dr.
James C. Emory, Robert B. Forest,W. Robert Widener, Robert K. Wilmouth, Robert
V. Head, Dr. Alan J. Rowe, James G. Rude, M.H. Schwartz, and Robert G. Stevens
were the founders of the society.
The meeting was followed by a
conference “Bridging the Gap between the Management Function and Information
Technology” held at the University of Minnesota in the year 1969. The
conference was attended by more than 250 persons. The SIM has founded many
programs for the purpose of furthering its founding goals and objectives. Some
of those programs are as follows:
§ Advanced Practices
Council: Also known by its abbreviated form APC, it is a platform of
discussion where experienced IT executives come together and decide to discuss
on various research-related aspects of IT. The council was established by
Warren McFarten in the year 1991. Mr. Warren McFarten comes from the Harvard
Business School.
§ Future
Potential Program in IT: It is yet another endeavor of the SIM to provide
progressive insights in the IT sectors and managerial aspects of the same. It
was created with the purpose of promoting IT as a progressive career option
among college students. This program was created by in partnership with
Microsoft, which later stopped funding the program since the year 2007.
§ Leadership Development
Roundtable: LDR is modeled on the popular Regional Leadership Forum (RLF)
and it addresses issues pertaining to leadership and development of
personality.
§ SIMposium: It is
conference that invites discussion upon issues relating to IT sectors, controversies,
new developments, amendments, etc. Till 2002, the conference was called SIM
Interchange Annual Conference.
Full Form of SIM: Space
Interferometry Mission
SIM Full Form stands for Space
Interferometry Mission. Also known as the SIM or SIM Lite or SIM Planet
Quest, refers to a space telescope that was created by the United States
National Aeronautics and Space Administration (NASA) in partnership with the
contractor Northrop Grumman. The telescope was created with the purpose of
finding small-sized planets that revolve in the possibly habitable areas of
stars other than the Sun. The telescope could not come into official use as it
was cancelled in the year 2010. Before its cancellation, the telescope was
intended to be launched in the year 2005, incorporated in the Evolved
Expendable Launch Vehicle (EELV) but due to insufficient budget, the launch
date was postponed many times.
The Purpose of the telescope was
not limited to the search of small-sized planets in the habitable areas near
stars but it could have helped in the mapping of the mysterious Milky Way
Galaxy. It could have performed other tasks like a collection of data from
stellar masses of stars, determination of the spatial aspects of dark matter in
galaxies, and in gravitational microlensing effect that helps in calculating
the mass of the stars. To achieve all these goals, the SIM would have used
optical interferometry. Optical Interferometry is a scientific technique
gathers light with the use of many mirrors combined in an interference pattern.
The technology used in the SIM is
advanced, as it can lead to the development of powerful telescopes capable of
capturing images extrasolar planets. This technology can be used to ascertain
whether those extrasolar planets have the capacity to sustain life forms. The
SIM used another advanced technology and that was termed as “rulers”. Rulers
have the ability to calculate in increments precisely. These rulers were
designed to work as networks and they had shock absorbers in them to reduce
vibrations during measurements.
SIM Full Form: Serving In Mission
Full Form of SIM stands for Serving
In Mission. It is a non-profit Christian mission organization. SIM is an
international, interdenominational organization that was established in the
year 1893. The founders of the SIM were Walter Gowans and Rowland Bingham, both
from Canada, and Thomas Kent from the USA. Originally, the SIM was known by the
name Soudan Interior Mission, with Soudan being a reference to Sudan of the
West Africa.
The organization, for many years,
underwent changes & few mergers and eventually, it settled for the
abbreviated form “SIM”. In French speaking nations, the organization is often
referred to as Société Internationale Missionnaire. The headquarter of the SIM
is located in Fort Mill, South Carolina, with many sending officers located in
different parts of the world like France, South Africa, South Korea, Belgium,
Singapore, Italy, New Zealand, the United States, Switzerland, and Australia.
The organization is an
amalgamation of many distinct organizations, whose own histories date back
hundred years ago. Those organizations include Africa Evangelical
Fellowship, International Christian Fellowship, Andes Evangelical
Mission and Sudan Interior Mission. Thus, the SIM is one of the most
prominent and recognized Christian missionary organizations.
Let us explore some historical
facts behind the establishment of the SIM. It all started from Sudan. The
founders, Water Gowans, Rowland Bingham and Thomas Kent, wanted to evangelize
the Sudanese region. The first base of the mission was founded in the year 1902
and eventually its reach expanded to other regions of the country and then of
the world. By the year 1998, the SIM had covered areas like Guinea, Niger,
Nigeria, Senegal, Kenya, Liberia, Malawi, South Africa, Sudan, and Togo, etc.
In 1989, the SIM had merged with
International Christian Fellowship and with this merger, the SIM extended its
reach to south Asian regions like Bangladesh, China, Nepal, India, Philippines,
Mongolia, Pakistan, etc. In the year 1998, the SIM merged with Africa
Evangelical Fellowship (AEF).
The purpose of the mission is to
evangelize and attend to needs of people; educate Christians to respect values
of Church; and to train churches and other Christian mission. As far as records
of the year 2008 are concerned, the SIM has about 1800 missionaries actively
engaged in about 37 countries, primarily in the regions belonging to South
America, Africa, and Asia.
Full Form of SIM: School for
Improvisational Music
SIM Full Form refers to School
for Improvisational Music. SIM is a part of the Center for Improvisational
Music (CIM) established with the purpose of educating students in creative
music. The SIM sincerely engages in training aspiring students about music and
since 2001, it has conducted about 20 interactive workshops, which have been
attended by more than 800 students. The sessions conducted by the SIM include
master classes, coaching, private tutoring, etc. The SIM brings together some
of the most talented and renowned improvisers from the fields relating to
contemporary music and jazz. The SIM provides sufficient opportunities to
aspiring students to learn about creative music.
