BotNet is a word derived from jargon term which means a collection of software robots or bots,which runs automatically. This Botnet is associated with malicious softwares.
A BotNet oprator sends out viruses and worms,which will infect ordinary computers.
BotNets are used for various process such as Click fraud,Spamdexing,SMTP mail replys,etc.,
Botnet lifecycle:
Bot-herder configures initial bot parameters such as infection vectors, payload, stealth, C&C details
1.Register a DDNS
2.Register a static IP
3.Bot-herder launches new bot(s)
4.Bots spread (ie.,viruses or worms)
5.Causes an increase of DDoS being sent to the victim
6.Losing bots to other botnets

BING is Bing Is Not Google
New Product from Microsoft "BING" is a search Engine
This is being launched in the market in competition of "Google" ,who have a big share og search engines in the current market.
I would say there is only one difference between them is the integration wallpapers and a new look to the search engine.
I would request you to have a look to this amazing new look of BING on YouTube.
The full form of BING is Bing Is Not Google

Bittorrent is a file sharing service in which files are shared between different people online called the peers. It is mainly used for sharing larger file. Uploaders (called the seeders) uploads their contents directly to the peers computer. And the downloaders , i.e. the peers also continue to upload the part of files downloaded by them to some other peers, and thats why it is called the peer to peer file sharing service. In this method there is no need of any mainframe storage. Only a tracker is needed which controls the entire file sharing system. Open source softwares like Utorrent, Fasttorrent, Vuge etc. are used to download and upload by using this method.
Though it is extremely helpful for sharing larger files, it is being misused by some dirty minds and it is used as a tool for piracy. Piracy of movies, piracy of music, piracy of books, softwares and so on. New released stuffs are easily found in those sites without spending a single penny. As a result, industry isfacing a huge loss of money.
These websites are earning huge amount of money using these pirated stuffs. These sites should be completely banned to prevent the piracy.
Introduction
Any device that include a computer but not itself a general purpose computer (the comp that we use at our home) is included in the field of embedded system. Thay are special purpose computer systems to perform one or few dedicated functions, often realtime. They are usually embedded as a part of a complete device including hardware,mechanical parts.
Range of ES is from digital cameras,watches mp3 players,traffic lights,factory controllers,system controlling nuclear plants,mobile phones ,consumer electronics : ovens,dish washers ,tv , home automation systems,medical equipment,transportation systems miniature wireless devices called motes..... the list goes on
Traditionally most of this systems are used for control and process measurement, as a side-effect of higher integration of integrated circuits more complex applications can be solved by embedded systems.
Early applications of embedded devices include the guidance computer of the Minuteman I missiles and the Apollo guidance computer. The Minuteman I & II missiles are intercontinental ballistic nuclear warheads, produced by Boeing in the 1960’s. Due to the large quantities of ICs used in the guidance system of Minuteman II missiles, prices for ICs fell from 1000$ each to 3$ each. This lead to wide adoption of embedded systems in consumerelectronics in the 1980’s.
Higher integration of integrated circuits more complex applications can be mapped as Hardware Evolution , various verticals where
Embedded systems has evolved are:
- application specific processors
- digital signalling processors
- general ppurpose microprocessors and microcontrollers
- system on chip(soc)
Embedded systems has multiple objectives ans design goals like
- affodablity
- reliablity
- performance
- energy efficiency.....
Embedded systems is a area of work that incorporate multiple disciplines like
- electronic hardware
- software
- control algorithm
there are various functional as well as non-functional requirements that the system must fulfill in order to be a succesfull product
Conclusion
As integrated circuits get continuously cheaper, more capable and power efficient, complexity of chip designs are constantly growing. This is illustrated by new design approaches such as SoC and multi-core technologies. To handle this increased complexity, existing tools offer functionality for various level of simulation and basic capabilities for synthesizing design given as formal descriptions.
