Low Noise Amplifiers are solitary of the electronic amplifiers which are utilizing to enlarge feeble or extremely feeble signals which are confining by antennas. These amplifiers are the most important element utilize in the radio recipient circuit. It decreases the haphazardness from dissimilar period of in receipt of signal. LNAs are premeditated to comprise especially lavishly gains and especially depleted haphazardness stimulant. This is completed to decrease the overall haphazardness pro...
As the top manager, the CEO is typically responsible for the entire operations of the corporation and reports directly to the chairman and board of directors. It is the CEO's responsibility to implement board decisions and initiatives and to maintain the smooth operation of the firm, with the assistance of senior management. Often, the CEO will also be designated as the company's president and will be one of the inside directors on the board (if not the chairman). Chief Operations Officer (CO...
1. ABSTRACT: This paper describes about mobile ad-hoc networks. In mobile ad-hoc networks the simulation tools plays a vital part. The main simulation tools used in MANETS are described in this paper elaborately. Various aspects of MANET routing protocols, quality of service and security issues of the simulated tools have been explained. Advantages and disadvantages of simulation tool software and test bed is explained. 2. INTRODUCTION: Mobile Ad-hoc network in simulation tool have been expla...
The paper discusses about one of the many DNS failures which can cause disruption for the efficient functioning of the network.One of the most challenging problems faced today is DNS amplication attacks.DNS amplication attacks mainly utilises IP spoofing and a larger number of open recursive DNS servers to carry out these attacks.The consequences of these attacks are disruption of transmission rate,consumption and wastage of bandwidth.There are a lot of "misconfigured" DNS servers out there. ...
ABSTRACT: Retrieving the stylus of a pen-based device takes time and requires a second hand. Especially for short intermittent interactions many users therefore choose to use their bare fingers. Although convenient, this increases targeting times and error rates. We argue that the main reasons are the occlusion of the target by the user's finger and ambiguity about which part of the finger defines the selection point. We propose a pointing technique we call Shift that is designed to address t...
Infrastructure less networks has found their significant place in the recent trends of engineering and technology. The research issues and challenges are paving the ways for the excellent research opportunities. In general, in wireless networking there are two main architectures: infrastructure (single-hop) networks and mobile ad hoc (multi-hop) networks. Even though users can handover between base stations or access points and roam among different networks, the conceit of mobility is limited...
The total cost of ownership (TCO) is not a concept unique to the information security field. TCO refers to the total monetary and lab or costs associated with purchasing, installing, and supporting IT hardware and software, calculated over a specific time period.The aim of TCO analysis is to identify, quantify, and ultimately, reduce the overall costs associated with ownership of networked assets. We have to consider about basically two types of costs. There are, Hard costs Hard cots are tang...
A Binary lock is a digital implementation of a key that is used to control access to a device. This can be achieved by associating any number of bits to guarantee the access. In real life example such as the ATM or the door lock, the key consists of 10 bit binary input (0-9) which gives 210 different code combinations to choose from. The input of the lock code in these cases is entered in serial form bit by bit. In this project, a 4 Bit Binary lock system is implemented and tested. The lock c...
For application Developers and database system providers, the Microsoft Open Database Connectivity acts as one of the standard programming interface. Before the arrival of ODBC, programmers using different appropriate languages for each database they were connecting but later on ODBC have become the default for windows programs. From the coding perspective, the data base system is almost irrelevant due to the choice of ODBC. ODBC has made the programmers or application developers to think muc...
1. INTRODUCTION Definition of the problem This research mainly deals about the multi threaded socket classes between the client and the server. In this the concept called threads are used by the developer but it is optional as its not yet decided whether it needs or not. Even detection can provide the feedback to the application where the socket classes and the other internet cannot provide. The following are the event detection methods provided: establishing the connection, dropping the conn...
