STD Full Form Name: STD Meaning
Full Form of STD:
Subscriber Trunk Dialing
STD Full Form is Subscriber
Trunk Dialing (or) Subscriber Toll Dialing. STD is a type of
telephonic system which allows users to make trunk calls independently without
the assistance of any operator. This term is, however, almost out of use in the
current system of technology and mobile usages. Nevertheless, STD was first
used to make long distance calls directly.
The term STD is commonly used in
Ireland, UK, India, South East Asia, and Australia. Whereas; in countries like
the USA the same terms is referred to as ‘Direct Distance Dialing’. The advent
of STD gave birth to individual STD code for every city based on certain
factors that represent the city name. With the introduction of mobiles, people
are able to make a call between states within the country without the need of
any STD code or prefix. Most often zero is used and this could differ from
country to country.
STD Full Form – Additional Information
Telecommunication has evolved a
lot over the past many years. It is easier to connect with a person in other
city or even another country by just dialing a code prior to the person’s
telephone number. This code is known as STD or Subscriber Trunk Dialing.
Earlier, when a person wanted to communicate over the telephone with another
person residing in a different city or country, the process of connecting the
two lines was done with the help of a telephone operator at the exchange.
There was no facility to connect
directly and dependency on the operator meant a long wait till the connection
between the two exchanges was established and then passed on to you. The system
ran thus. You had to make a call to your local exchange where the telephone
operator would receive it. This was called “Trunk Assistance”. The operator
would then note down the number of the person you wished to speak to and also
ask for the location of the call destination. Later, he/she would establish
inter- telephone exchange connection with the destination exchange.
After passing the desired call
number to the operator at the other end, that operator would then finally
connect you to the desired person. This was a metered and lengthy process and
after every 3 minutes the operator would cut in and inform that the time was
over and in case you wanted to speak more, you had to tell the operator to
extend the duration, else the call would get cut after 3 minutes.
Need for STD
There are times when you wish to
speak to someone urgently and, unfortunately, the person is outstation, then
under such circumstances going through the older process of connection is
agonizing. Most of the times, the operator declares regrets for unavailability
of an open connection and you have to wait endlessly to get through to the
desired number.
However, with the development of
the telecommunication system, the “third party assistance” of the telephone
operator is eliminated. Each city has an assigned code for easy reference and
by dialing this code you can establish a direct contact with the telephone
exchange in that city.
When a person makes a call within
the city, it is treated as “local call”. When the call is intercity, then it is
a “trunk call” or STD call. On the other hand, if you have to dial a number in
a foreign country then it is “international subscriber dialing” or ISD call.
STD call not only eliminates the
operator system but also gives the subscriber to talk uninterruptedly for the
desired duration. Nonetheless, this is only possible when you make a call from
home, as it is direct dialing. But if you make a call from the telephone booth,
there is a meter connected to the telephone that records the call duration and
the booth owner keeps reminding like the operator about time duration, which
one needs to extend if need be. Finally, the meter calculates the charges as
per the duration of call and dialing rate.
STD Explained
When a person dials in the local
circle, it is treated as a standard local call. However, if you need to make an
outstation call, then the first line owner (caller) is also known as the
“subscriber” and since he rents the trunk line to make a call it is known as
Subscriber Trunk Dialing (STD). Now since the process has been made direct,
there is no interruption during the call.
Nonetheless, your STD calls are metered
and the final billing has local calls and STD calls charged at a different
rate. There are two national telephonic service providers – MTNL and BSNL. In
India, MTNL is Mahanagar Telephone Nigam Limited, which is operational in metro
cities (Maha =metro/big and Nagar = city) like Mumbai and New Delhi. Whereas
BSNL stands for Bharat Sanchar Nigam Limited and it provides services to all
other parts of India. So a “subscriber” means any person who has applied to
rent a telephone line through these providers.
Whenever the subscriber makes any
calls, these are passed through the telecommunication network of either MTNL or
BSNL, as the case may be. With the growing population and rising demand for
communication, private companies have joined the bandwagon of telecommunication
service providers. They are Bharti Airtel, Reliance Communications, and Tata
Indicom.
Forming STD Codes
STD codes are made to
differentiate the area you are calling. The access codes are made zone wise. It
implies international country codes as well as intercity codes. For example,
the USA country code is +1 and that of India is +91. For international dialing
one has to prefix 00 before the country code and in trunk dialing the prefix is
0.
The STD codes of metro cities are
usually double digit numbers, example New Delhi is 11, Mumbai is 22, Chennai is
44 and Pune are 20. Thus, while dialing a Pune landline number one should dial
020 followed by the number.
As far as 2-tier cities are
concerned, STD code is composed of 3 digits. Some examples are 422 is
Coimbatore in Tamil Nadu, 484 is Kochi in Kerala, 821 is Mysore in Karnataka
and 261 is Surat in Gujarat and so on. Thus, a call to a landline in Coimbatore
would start with 0422 followed by the number.
These codes may be difficult to
remember at all times; however, the Government and telecommunications
department has released a book with the entire Indian cities’ STD codes. The
STD codes directory gives an extensive listing of not only metros and 2-tier
cities but also remote villages in India where the telecom network is
available.
STD – A Boon for Communication Medium
With ever progressing country and
rapidly growing cities, it is very important to have a hassle-free mode of
communication. There is always an urge to move fast and thus no scope for
snail-like communication. So it is a relief to know that there is no more
waiting for the operator to connect your call when you can easily do it
yourself using the STD code facility. The national service providers, as well
as the private companies, make sure that the subscriber gets the best ever
service and that there is an uninterrupted connection between the two parties.
With the addition of private
telecom operators, the subscribers get the benefit of lower calling rate as
there is competition between the providers to woo the customers. Whether one
wants to call a friend or relative or make a vital business communication, STD
eases the process of connecting with the other party. It is swift, direct and
an absolute need of the hour.
STD Full Form: Sexually Transmitted Diseases
Full Form of STD stands
for Sexually Transmitted Diseases. One of the most
rapidly spreading diseases in the world is the Sexually Transmitted Diseases
(STDs). Also referred to as venereal diseases or sexually transmitted
infections, these diseases are basically infections that spread through sexual
intercourse, particularly vaginal intercourse, anal sex, and oral sex.
The major problem with these
diseases is that diseases do not generally show any symptoms and that is why
passing of the infections go undetected. However, most commonly reported
symptoms include vaginal discharge, ulcers near genital areas, penile
discharge, and pelvic pain. Most of the STDs are sexually transmitted however,
there have been cases where STDs can spread through non-sexual contacts like
breastfeeding or during childbirth. Diagnostic tests for STDs are far more
developed and easily available in developed countries than developing
countries.
There are about around 30
different kinds of bacteria, parasites, and viruses that are responsible for
sexually transmitted. Some of the bacterial STDs are gonorrhea, Chlamydia, and
syphilis. Examples of viral STDs are genital herpes, genital warts, and
HIV/AIDS. Trichomoniasis is an example of parasitic STD.Restraining from sexual
intercourse is the best way of preventing STDs. Some of the ways to prevent
contraction of sexually transmitted diseases are as follows:
§
Vaccination
Vaccination is considered one of
the most plausible methods of prevention, however, as far as STDs are
concerned, one may not find a substantial number of vaccines. Nevertheless,
there are vaccines that are available to develop immunity against certain types
of STDs. Vaccines are available on viral STDs like Hepatitis A, Hepatitis B,
and some kinds of HPV (Human Papilloma Virus). Doctors advise vaccination
before sexual intercourse.
§
Condoms
Public awareness programs about
sexually transmitted diseases have extensively promoted the use of condoms.
Condoms are considered most convenient methods of prevention of STDs and they
are heavily marketed as a part of the public awareness program. However,
condoms only provide limited protection, as the uncovered areas may still be
susceptible to infections.
HIV is mostly caused through
sexual intercourse and therefore, it is advisable that the penis is properly
covered with a condom so that the infection does not spread through any broken
skin. However, it is advisable that sexual intercourse should not happen when
there are injuries near private parts. Old condoms or used condoms should be
disposed off and be considered infectious.
An individual can contract STDs
at any age but women who are under the age of 25 and are sexually active and
women above the age of 25 should undergo screening tests for STDs like
Chlamydia and gonorrhea every year. Nucleic Acid Amplification tests are the
most recommended methods of diagnosis for the STDs gonorrhea and Chlamydia. The
diagnosis can be made on urine or genital swabs.
Testing can be done for a single
infection or variety of infections. Early diagnosis and identification will
help in arresting the effect.Sexually transmitted diseases can have fatal
effects on the body and therefore, careful management of one’s health should be
a priority. Regular check-ups, wise decisions, and healthy diet can be key to
good immunity system
Full Form of STD: State Transition Diagram
STD Full Form refers to State
Transition Diagram. Object-oriented modeling makes use of State
Transition Diagram (STD). The concept has been used since the beginning. The
fundamental design of the STD is to define the machine that consists of a
number of states. In this concept, external factors cause the transition in the
state of the machine. What happens is that machine obtains external factors,
which result in a change from one state to another.
STD came even before object
modeling concept. These diagrams are utilized because they give a formal
definition of behavior. However, there are certain problems pertaining to the
application of STD. The biggest problem is that in order to use STD, it is
necessary to define all states of the system concerned. This will not be an
issue if it is to be applied to small and uncomplicated systems but in a case
of larger and complex systems, there is an increase in states and this causes
problems in application.
This rise in a number of states
is called state explosion and this problem makes systems too complicated for
any practical use. It is, therefore, important to handle this state explosion
issue. State explosion issue can be done away with by means of object-oriented
methods that provide distinct state transition diagrams for every class. This
results in simplification of every class and the transition is then feasible.
Of all the kinds of State
Transition Diagram in object methods, the Harel Statechart is the most popular.
The variety was invented by Rumbaugh and it is considered to be one of the most
practical, effective, powerful forms of the STD. Of its many features, its
ability to generalize states, facilitating digging out common transitions of
states is the most impressive one. Additionally, the Harel Statechart method
provides room for convenient management of processing, actions, and activities.
Actions refer to instantaneous
processes, that is, they cannot be interrupted. These types of processes can be
attached to the transitions or the beginning or commencement of a state. On the
other hand, activities refer to long processes that can be interfered with and
are attached or bound to states. Sometimes certain conditions are attached to
processes, then the transition shall only happen when the condition is
successfully fulfilled.STDs are preferred for defining the behavior of a
single, uncomplicated object.
STD Full Form: Sacrae Theologiae Doctor
Full Form of STD refers to Sacrae
Theologiae Doctor. A doctorate degree is considered to be the
final step towards completion of the academic learning process. It indicates
that the degree holder has delved into the depths of a subject, thoroughly
researched its minor and major aspects, and come up with certain conclusions.
It is because of this, a doctorate degree is considered one of the most
valuable academic qualifications a person could obtain.
For the purpose of this article,
we shall take up Sacrae Theologiae Doctor, which is also known as Doctor of
Sacred Theology or Professor of Sacred Theology. It is the final degree one can
obtain in theology in a pontifical university system of the Catholic Church.
The degree takes up the lessons
from the Bachelor of Sacred Theology (BST) and the Licentiate of Sacred
Theology (STL) and provides deeper insights into them. In order to become
eligible to STD, one has to attain the aforementioned degrees, STL, and BST.
BST is a three years degree course that a student can take only if he has done
minimum two years undergraduate study in the subject of Philosophy. SL follows BST
and is a two years course. When a person has successfully attained the
above-mentioned qualifications, he becomes eligible for STD, which he receives
only when his doctoral dissertation is accepted and published.
There are many advantages
appended to an STD degree. The STD or the Doctor of Canon Law (DCL or JCD) is
the most preferred qualification in the teaching professions. Many countries
mandate an STD or DCL degree to become eligible for teaching positions for the
subject of Theology in Catholic universities. In fact, many universities
stipulate the requirement of an STD degree for applicants to secure
administrative jobs in the university. An STD degree can give an edge over
other applicants for teaching positions and help you secure permanent posts on
the theology teaching staff of a pontifical university. There can, however, be
more stringent requirements, depending upon the university.
As mentioned above, the STD
degree was also known as Professor of Sacred theology. This holds relevance
because the degree inscriptions can be found in British churches, where the
abbreviation ‘STD’ is used to denote these degree holders as the degree holders
of Doctor of Divinity, which is an honorary degree in divinity. The practice of
referring to the degree of Doctor of Divinity as STD is no longer prevalent
however confusion still remains among the common public regarding the
distinctiveness between these degrees. The result is that it is not uncommon to
find people referring to both these degrees interchangeably.
