358. Q. & A.s SCI. & TECH. – 22


Q. &  A.s  ‑‑‑  SCI.  &  TECH. – 22


601Q. What is spyware?
Spyware is Internet jargon for Advertising Supported software (Adware). It is a way for shareware authors to make money from a product, other than by selling it to the users.
There are several large media companies that offer them to place banner ads in their products in exchange for a portion of the revenue from banner sales.
This way, you don't have to pay for the software and the developers are still getting paid. If you find the banners annoying, there is usually an option to remove them, by paying the regular licensing fee.

602Q. Why is it called "Spyware" ?
While this may be a great concept, the downside is that the advertising companies also install additional tracking software on your system, which is continuously "calling home", using your Internet connection and reports statistical data to the "mothership". While according to the privacy policies of the companies, there will be no sensitive or identifying data collected from your system and you shall remain anonymous, it still remains the fact, that you have a "live" server sitting on your PC that is sending information about you and your surfing habits to a remote location.....
603Q. Are all Adware products "Spyware"?
No, but the majority are. There are also products that do display advertising but do not install any tracking mechanism on your system. These products are not indexed in our database.
604Q. Is Spyware illegal?
Even though the name may indicate so, Spyware is not an illegal type of software in any way. However there are certain issues that a privacy oriented user may object to and therefore prefer not to use the product. This usually involves the tracking and sending of data and statistics via a server installed on the user's PC and the use of your Internet connection in the background.
605Q. What’s the hype about?
While legitimate adware companies will disclose the nature of data that is collected and transmitted in their privacy statement (linked from our database), there is almost no way for the user to actually control what data is being sent. The fact is that the technology is in theory capable of sending much more than just banner statistics – and this is why many people feel uncomfortable with the idea.

610Q. Spyware Detector Antispyware News:
*Spyware is becoming more and more insidious everyday. A recent corporate spyware/adware audit of more than 12,200 systems, representing more than 4,900 companies discovered an average of 22 pieces of spyware per corporate desktop computer, including malicious spyware and adware infections. On average eight percent of the corporate PCs in all networks audited had system monitors and six percent had Trojan horse programs, the two most nefarious and potentially malicious forms of spyware.
611Q. What is called Malware?
Malware: Malware is a generic term for any malicious software designed to disrupt the working of a network. Virus, worms and Trojans fall under the category of Malware. Malware utilize popular communication tools to spread, including worms sent through email and instant messages, Trojan horses dropped from web sites, and virus-infected files downloaded from peer-to-peer connections. Malware seek to exploit existing vulnerabilities on systems making their entry quiet and easy.
612Q. What are called Trojans?
Trojans: Redirects victims machines to specified websites or other Internet resources. Clickers either send the necessary commands to the browser or replace system files where standard Internet urls are stored. Clickers are used: 1. To raise the hit-count of a specific site for advertising purposes. 2. To organize a DoS attack on a specified server or site. 3. To lead the victim to an infected resource where the machine will be attacked by other malware (viruses or Trojans).

613Q. What are called spy tools?
Spy tools: are programs which steal information from users PC such as banking information, login details and keyboard strokes etc.
614Q. What is called Keylogger?
Keylogger: is a program that captures and logs keystrokes on the computer without the user's knowledge and consent. The logged data is typically sent to a remote attacker. The keylogger is usually hidden from the user and may use cloaking (Rootkit) technology to hide from other software in order to evade easy detection by anti-Spyware applications.

618Q. The first decline in the theatrical 3-D craze started in August and September 1953. The factors causing this decline were:
  • Two prints had to be projected simultaneously.
  • The prints had to remain exactly alike after repair, or synchronization would be lost.
  • It sometimes required two projectionists to keep sync working properly.
  • When either prints or shutters became out of sync, the picture became virtually unwatchable and accounted for headaches and eyestrain.
  • The necessary silver projection screen was very directional and caused sideline seating to be unusable with both 3-D and regular films, due to the angular darkening of these screens. Later films that opened in wider-seated venues often premiered flat for that reason (such at Kiss Me Kate at the Radio City Music Hall).

619Q.  What are the differences between Transistor and Memristor?
 Transistor
Memristor
1]  3-terminal switching device with an input electrode (e.g. source), an output electrode (e.g. drain), and a control electrode (e.g. gate)
1]  2-terminal device with one of the electrodes acting either as a control electrode or a source electrode depending on the voltage magnitude.
2] Requires a power source to retain a data state
2]  Does not require a power source to retain a data state
3]  Stores data by electron charge
3]  Stores data by resistance state
4]  Scalable by reducing the lateral length and width dimensions between the input and output electrodes
4]  Scalable by reducing the thickness of the memristor materials
5]  Capable of performing analog or digital electronic functions depending on applied bias voltages
5]  Capable of performing analog or digital electronic functions depending on particular material used for memristor
6]  Fabrication requires optical lithography
6]  Fabrication by optical lithography but alternative (potentially cheaper) mass production techniques such as nanoimprint lithography and self assembly have also been implemented


620Q. What is non-volatile memory?
As evident from the patent data, non-volatile memory is the dominant area being pursued for memristor technology. Of course most of the companies listed (with the exception of Hewlett Packard) do not refer to their memory in terms of the memristor and rather use a variety of acronyms (i.e. RRAM or ReRAM, CBRAM, PRAM, etc.) to distinguish their particular memory design. While these acronyms do represent real distinctions in terms of the materials used or the mechanism of resistance switching employed, the materials are still all memristors because they all share the same characteristic voltage-induced resistance switching behavior covered by the mathematical memristor model of Chua.

621Q. Transistor means what?
Flash memory currently dominates the semiconductor memory market. However, each memory cell of flash requires at least one transistor meaning that flash design is highly susceptible to an end to Moore’s law. On the other hand, memristor memory design is often based on a crossbar architecture which does not require transistors in the memory cells. Although transistors are still necessary for the read/write circuitry, the total number of transistors for a million memory cells can be on the order of thousands instead of millions and the potential for addressing trillions of memory cells exists using only millions (instead of trillions) of transistors.
Another fundamental limitation to conventional memory architectures is Von Neumann’s bottleneck which makes it more difficult to locate information as memory density increases.
Memristors offer a way to overcome this hurdle since they can integrate memory and processing functions in a common circuit architecture providing a de-segregation between processing circuitry and data storage circuitry .

622Q. What is Neuromorphic Electronics  ?
Neuromorphic Electronics 
Neuromorphics has been defined in terms of electronic analog circuits that mimic neuro-biological architectures. Since the early papers of Leon Chua it was noted that the equations of the memristor were closely related to the Hodgkin-Huxley model describing the behavior of neural cells. Since memristors integrate aspects of both memory storage and signal processing in a similar manner to neural synapses they may be ideal to create a synthetic electronic system similar to the human brain capable of handling applications such as pattern recognition and adaptive control of robotics better than what is achievable with modern computer architectures. While so far few patents have been issued involving memristors applied to this area, several research groups are beginning to pursue this approach and several publications from HPLabs (Greg Snider) and other researchers (M Di Ventra, Y.V. Pershin) are exploring the possibilites in this area. Some other potential applications of memristors related to this area are discussed in my other knol

623Q. What is Binary Oxide?
 Binary Oxide 
The discovery of the resistive switching properties of binary oxide compounds actually predates the original memristor paper of Chua and can be dated back to 1967 when the article "New conduction and reversible memory phenomena in thin insulating films" was published in the Proceedings of the Royal Society.
The phenomena was originally observed in silicon oxide formed with nanometer scale thickness and including gold ions. Silicon oxides have been a key insulating material used in the fabricating of electronics devices over the past 40 years.
However, there is now a search for new thin oxide films having improved insulating properties to assist in the further scaling of transistor designs. This search may be very beneficial to this class of memristor material since research in new binary oxide compounds may benefit both the conventional semiconductor industry and the upcoming memristor industry.
Furthermore, the manufacturing resources used in semiconductor processes may require less modification in comparison with other memristor materials and provide a smooth transition as semiconductor electronics is converted to memristor electronics over the next few decades.
While Samsung has some patents covering variations of binary oxide memristors there is still significant freedom to operate based on early published patents which are now expired such as US Patent 4,839,700 which teaches a variety of binary oxides such as WO3, Ir2O3, MoO3, ZrO2, and RhO2 adjusted to have memristive properties. A variety of other memristor variations based on TiO, CuO, NiO, ZrO, and HfO materials have been under experimental investigation for the past several years. Hewlett-Packard has been focusing on a TiO variation of the memristor but does not yet have any patents covering their materials or the manufacture. 

624Q. What is HyperPhysics?
