For ongoing monitoring of the network administrator's computer or server program is installed to monitor the network. It is desirable that the program does not require installing additional applications other machines, so as not to distract employees from their work. After installing this program scans the network and identifies all the devices in it. Thus, the administrator does not need to own make a list of hosts within its network. Poll hosts must take place remotely, so again, do not interrupt your workflow.

The program for monitoring network should be supported by sets of checks to help system administrator might have time to learn about any failures in the network and quickly eliminate them. First of all, a program for monitoring network should be able to continuously check the connection to different ports Protocol TCP / IP. Why is this important? First of all, so check availability and status of the server or any other host on the network. Periodically polling, for example, TCP-port, you can find out in time for termination of another device, without leaving your desk. This allows the system administrator to react in time and fix your problem. Second, by monitoring specific TCP ports can be early detection of malicious software. When you set up multiple tests on certain ports, network monitoring program must notify the administrator when opening a port of monitored by a range of ports (the list of ports used by malicious programs, can be found online). Most important is the monitoring device via ARP and NetBIOS protocols.

Valery Klimenko (Ph.D.) An important feature of the modules Logic, Layout, Router software PADS, created by Mentor Graphics for designing printed circuit boards (PCB), is the presence of automation as part of Object Linking and Embedding (OLE) 1. Automation includes the server and client. Speaking as the servers are, PADS provides its data and functionality of other programs, as well as the client can use the data and the functionality of other programs. This means in particular that automation as part of OLE creates the preconditions for a harmonious integration of modules in the PADS software environment of the enterprise. The presence of such assumptions, however, is often underestimated in practice they are implemented, usually in very limited extent.

At the same time, OLE and its elements can be used with high efficiency to address the very urgent practical problems, for example, to comply with the PP in these special projects requirements that are not reflected in the PADS Design Rules. Specific design requirements are usually formulated by various parties – the developer of the concept, a specialist in electromagnetic compatibility, the manufacturer of PP … – And stored in different documents. The maximum objective is to provided by means of OLE in a certain way to introduce these documents to the project and possibly contribute to the implementation of automatic design of their requirements. Analogue of this is the impact of Design Rules and Preferences for work tools PADS. Recorded in the Design Rules and Preferences settings are taken into account two types of instruments PADS: design and control.

In this article I want to share my experience: to tell you how important it is to use the licensed software manimeykera and how to make money on it. This of course will focus on licensing software critical relevance – operating system, antivirus, firewall, anti-spam … Agree, this software is virtually on any computer connected to the Internet – it is vital. But here is the quality of it … and how can he trust – is the question. So what problems may arise in this regard? Yes, of course, far too many people in the CIS use pirated software.

It is as if to say – historically, that is developed. Prices on a license can be very pronounced, and 'very heavy' for most users. The Internet was a novelty. And why spend a significant amount to the program, if any radio market you can buy for ridiculous money drive a whole set of various pirated software, the total value of which is thousands of dollars. But let's see! As mentioned above, this is a critical software such as operating system or antivirus – packages such as Delphi or CorelDraw worth thousands of dollars not be considered. Answer yourself the question – installing on your computer, cracked or hacked Vindous antivirus – how can you be confident in the reliability of this software? What guarantee is there that the worst case the system has not built a malicious code, and at best – it will work correctly, will not admit fault and do not miss the bugs? How to update an unlicensed Vindous, which does not pass check on servers Microsoft Update? But this update is often vital – it is through the hole in the creation of Bill Gates & Co.

Hello, dear visitors! I want to tell you about the site Soft4you – Universal Portal. What can we offer you? We can offer you lots of useful things for yourself! What exactly, you ask. My answer is – absolutely everything! You a lot of data and you do not have enough space on your hard drive? Here you can naytti latest versions of archivers.

Therefore, I ask all to visit us on Soft4you!!!

Design software called the development, design, maintenance and documentation of software. At the same time apply a variety of technology areas such as informatics, design, subject area, project management, management of digital content and interface design. In the process of software design to define and implement the mandatory inspection characteristics of the program. Test software to test characteristics such as reliability, functionality, usability, availability and portability. The program must meet all requirements, from design to technical nuances. In designing the software and of no small importance are the properties directly in the design process, these include the duration of development and emerging process risks. Software development process is divided into three stages: Stage One: preparation of technical project. Software development can be compared with the construction of the house.

Neither house is not built without design. Start developing software bypassing the stage of a detailed specification is unthinkable. And to make a good technical job to analyze the business processes around the company, its the need for automation, to explore the IT infrastructure and software used. What is described in the specification? It described in detail all the functions to be performed by a program wishes customer of the software, plus technical information database structure, the structure of window applications, the logic of action programs, etc. Draw up terms of reference – it is quite difficult and responsible task to perform that only by a professional programmer.

Terms of reference to time is 5 to 30 business days (perhaps more). When TOR is made, we can already imagine the amount of work, cost and deadlines. Stage Two: programming and testing software. Once the requirements specification and the signing of the development, start programming. At this stage, involve not only specialists in programming, but both managers and designers. Finally, each product must be tested. This allows us to identify and correct errors. Phase Three: Implementation of software and technical support. After development of the program if it complies with the terms of reference, are starting to adopt software developed in the acting business. At this stage the errors found in the work usually easily corrected.
