Push media is any media marketing strategy in which the products being marketed are being suggested to the customers. Just as the term suggests, the products are pushed at the customers. Push Media is a producer of a good and service, promoting the same product to an audience to find relevance in it. Push media involves very little interaction with the audience of the product. … [Read more...] about Push Media

Technipages Explains Push Media

Push Media is a series of new content-delivery mechanisms on the Internet, in which users subscribe to what amounts to a broadcasting service. This subsequently delivers content to the user’s computer without the user having to make further requests for information. In contrast, to pull media, which must attract the user to the site, it can guarantee advertisers that subscribers will continue to receive updates and view advertising banners.
Among the various models that have been developed are applications such as PointCast that deliver news, weather, and sports scores to the user’s screen saver, and services such as Castanet, which employ a radio metaphor. The user tunes to a channel and content are delivered to the user whenever updates are available. The produced content may appear in a unique window that appears on the user’s desktop. Castanet can also automatically deliver software and updates to software, and thus creates a new and potentially significant model for software distribution and maintenance.

Common Uses of Push Media

• Push media involves creativity and very little interaction with the audience of the product.
• Push media, as the name implies intends to sell the idea of a product to an audience and this is done by explaining what a product does to them.
• The push media technique of marketing has now influenced the digital and social media space.

Common Misuses of Push Media

• Push media involves only the use of social media and not pushing a product around in a trolley.

In cryptography, a revolutionary new method of encryption that does not require the message’s receiver to have received the decoding key in a separate transmission. The need to send the key, which is required to decode the message, is the chief vulnerability of previous encryption techniques. In public-key cryptography, there are two keys: a public one and a private one. The … [Read more...] about Public Key Cryptography

Technipages Explains Public Key Cryptography

Public key cryptography also called Asymmetric Key cryptography, is a system of encryption which is based on the use of two virtual keys, the private key, and the public key. The private key is used to decrypt a message while the public key is used to encrypt the message. In this model, once a message is encrypted by the public key, only the private key can decrypt the message. Just as the name of the key depicts, the private key is meant to be private so that only the handler of the key can access the message, unlike the public key which can be encrypted by anyone.

The keys are virtual keys, and the private and public keys are large numerical values used to encrypt and decrypt data.  The keys are produced by a trusted authority trusted by both parties. The private key is usually held by the generator of the key pair, while the public key, to anyone who wants to send data.

In 1977, public key cryptography was published by Whitfield-Diffie and Martin Hellman, but it was initially formulated by James Ellis. But even neither of them could devise applications of these in a practical world. Rivest-Shamir-Adleman was the first to publish a working public key cryptography system.

Common Uses of Public Key Cryptography

• Public key cryptography is a modern cryptographic process  for communicating  securely without having previously agreed upon the secret key
• In public key cryptography, it utilizes a pair of keys to establish secure communication.
• Public key cryptography brings major security technologies to the desktop in the Windows 2000 environment.

Common Misuses of Public Key Cryptography

• Public key cryptography doesn’t allow for non-repudiation so the sender can deny sending a message
•  In public key cryptography, when a private key is lost, there are other ways to decrypt the message

Parameter passing convention in a programming language, is the method used to pass one or more values (called actual parameters) to a function by means of a function call, such as the following: square (2); This function call launches a function that squares the supplied parameter (2), returning 4. One fundamental difference among programming languages concerns what is done … [Read more...] about Parameter Passing Convention

Technipages Explains Parameter Passing Convention

Passing parameter convention is a technique in programming, in which an actual parameter is passed to a function; this happens when a function calls another function. A parameter is an intrinsic property of the procedure which is included in its definition, and there are formal parameters and actual parameters.

Formal parameters are usually written in the function prototype, and function header of the definition, i.e. they appear in function declarations. An actual parameter is the values passed in the call of a function, i.e. they appear in the function call.

So when a function is called, the actual parameters are passed, which are also known as arguments. Service is called by invocation, which is either by value or reference. In the call by value, the function creates its copy of the argument (actual parameter) and then uses it, it replicates the value of the actual parameter. The call by reference, the function when called, refers to another value (original) which is under a different name. The formal parameter becomes a reference to the actual parameter in calling a function.

It is practiced in the C and C++ programming languages, and Java only supports a call by value. All C functions are written using functions to make them re-usable and understandable.

Common Uses of Parameter Passing Convention

• Parameter passing convention is only applicable to C programs languages, and java only supports a function called by value.
• Parameter passing convention is used for passing objects on Foundation Classes method calls is if the object is mandatory, pass by reference; if it is optional pass by the pointer.’
• Parameter passing convention is used in C programs, and functions calling make c programs re-usable and understandable

Common Misuses of Parameter Passing Convention

• When parameter passing convention is exhibited, actual parameters are not sent, so a function does not call another.
• When a parameter passing convention calls a parameter by reference, the parameter creates a copy of itself and then uses it

A patent is a form of intellectual property (IP) protection that is designed to protect inventions; creative works (such as books and musical recordings) are protected by copyright. U.S. patents protect inventors for 20 years, during which time the holder—not necessarily the same person as the inventor—can exclude others from making use of the technology that the protects. … [Read more...] about Patent

Technipages Explains Patent

A patent is a law that allows an individual or group of individuals to own an invention, and this could be a piece of technology, theorems, or regulations. Patents are granted to designs that are useful, un-ambiguous, and new. If a patent is granted, a fee has to be paid to maintain the patent, or else it is abandoned.
A patent is granted to the first person to apply for it, in a case of multiple inventors. When a patent is granted, it applies for 20 years, starting from the date of application. A patent does not allow any other person to commercialize the product for that period. On the expiration of the patent, it is then made available for public use, from which anyone can modify, rebrand, or sell it. A patent cannot be re-applied for.
Early patent law required that before the invention is submitted alongside the application for the patent. After the patent has been filed for, a patent examination is initiated in which the patent office examines the patent to examine the patentability of the invention. The public is sometimes involved in helping to determine the patency of an invention by recognizing prior arts, as this would help to show the originality of an invention.

Common Uses of Patent

• Before a patent is awarded, after its application, an examination is carried out to verify the novelty of the invention
• If a patent is granted, the period of a patent lasts for 20 years, starting from the day the patent was applied
• In a case where there are a lot of inventors for a product, and the person files a patent gets to be the one who keeps the product

Common Misuses of Patent

• A patent examination does not work with the public to make findings as to recognizing if there has been any prior look-alike invention.
• One interesting fact to know is that most scientists refuse to file for a patent for their newly discovered technique, products, etc. to make the cost of it reaching the public cheaper
