No matter where you are responsible, it is strongly recommended that you take care of your personal computer to take over if you want to avoid such problems. It is true that nothing can be guaranteed, but it’s worth it to take, take precautions. One of them is to keep the paperwork that came with your PC or Mac, where it was purchased, while another precaution to help you keep up to date with the free download anti-virus.

Many people often wonder why it is necessary to keep anti-virus downloads. The reason is quite simple: Every day we see new deadly viruses and other programs are written. No one knows the identity of the person or persons behind what became known that diseases of cyberspace, but what we do know with certainty that can very effectively remove downloads for anti virus.

Any personal computer that is updated with modern features like anti-virus downloads a bullet-proof. Yes it is true that people are developing new and dangerous viruses, there are other specialists who work twice as hard to the door, and that’s what happens when we take advantage of free downloads anti virus. Here we arm our system to identify troublesome viruses, so they can destroy them or stop them before they cause damage.

Who a modern and up to date anti-virus downloads needs have to download to the internet and all they need to connect. In addition, most PCs to their customers to show these updates are available on their own, and you’ll be notified for new software.

Please do not take the problem of computer viruses easily because they can literally destroy your computer, and we talk about the destruction that you guarantee to buy a new one. It’s something I doubt you are willing to do now. So log on to the internet and more details about downloads to date antivirus software.

However, Firefox has come in and turned many users of Internet Explorer. In fact, instead of Internet Explorer web browser on the market share of 95.5%, but slipped to 92.9% in the past few months, Firefox’s trial version on the market has had. This may be only a few percentage points but those points represent millions of people have passed from IE to Firefox. In fact, about 23 million copies of Firefox preview uploaded.

So what does this mean for IE and Firefox? Who will win the browser war? If Firefox continues to gain market share, as it is, then Firefox could come out on top. However, if IE is trying to solve their security problems, he can probably keep its 90% plus one share. Only time has the answer, we wait to see easily.

Simple and effective. That’s what I was looking for. If the sender to your whitelist e-mail to you, it is necessary to respond to e-mail verification. And if it is validated, the e-mail will be able to reach. Spam bots are not able to cheat the system.

Once I had an e-mail account is spam received every 5 minutes, and coming in like crazy. He is frustrated, and you can not, if your e-mail account to do with the function of Boxtrapper. Think again, you need protection from spam e-mail your e-mail. And of course, not all web hosting package, this

A good host to good e-mail system and a messaging system must be good protection against spam effectively. That’s what I think.

After an IP address is like having a name on a network. To identify a computer on a network (LAN, WAN or the Internet), it must have an IP address. This figure is similar to a phone number or zip code. He is single and without him, the device or computer can not be used on a network. In an isolated network computers, various random IP addresses are assigned, but if a private network must be connected to the Internet to IP, so that its uniqueness is checked recorded.

This gives me my IP address?
The IP address can be static or dynamic, ie they may be the same when you are online or it can change. The IP address from a server through a service called DHCP (Dynamic Host Configuration Protocol) provided

Although things may be quite complicated to explain the characters and their meaning, it is only a small and easy to understand introduction to the IP address does not contain technical terms to understand. The significance of this data is very high, because in this short explanation, we can truly understand the need and the impact of the virtual IP address and geolocation.

This encryption method is simply described, the language understood in a new book called “Geeks On Call Wireless Network: 5-Minute Fixes” (Wiley, to $ 14.95). The book also offers expert advice and explanations, step by step, with topics ranging from configuring a wireless router to troubleshoot a slow connection.

can Here are a few additional tips from the book that will help protect your wireless network.

Reduce the scope of your network. This can keep nosy neighbors from entering your login. Move to reduce your wireless router in the center of your home and power settings.

Select a new password. Most routers have a default password “admin”. Make sure to change it.

Disable SSID Broadcast. Most wireless routers combine broadcast the names of the user’s network (SSID) and other users. This could be a security risk.

Use encryption to protect credit card information you send wirelessly to the Web. Also use your card at a website, is to find the SSL-encryption (up to a padlock in the corner of the site).

Disable Wireless Card when not in use. There is no better way to secure your computer.

Use a firewall, which is a program that protects your computer against Internet criminals.

Please do not use shared files. Remove all important documents in your folder shared files from access to a public network.

If you have a wireless laptop, disable the function that you try to connect your laptop to wireless networks available. For most Windows-based notebooks, double-click the wireless icon in the lower right corner of Windows. Then click Properties. Click on the Network “Wireless” Menu. Then click on Advanced. Uncheck the “Automatically connect to non-preferred networks” option. Finally, you click on Close.

It is important to distinguish between functional or regression testing and load or performance testing. Functional testing and regression testing is used to automate a large number of scenarios to ensure that your site works as expected. Load tests on the other hand gauges how well your website performs when subjected to a heavy load, how many concurrent users.

Load and performance requires the use of automated testing tools. It is impossible, if not ridiculous to try to simulate a load of 200 concurrent users by a group of 200 people sit on 200 machines and try to perform operations simultaneously. Before you start any kind of load and performance tests, you must determine the test cases you need to automate. A load test tool is typically save web requests and responses based on user interactions with a website. As you perform various operations on your site or application, the tool records all Web transactions that take place. If the recording is stopped, it generates an automated script. Otherwise, you can create the tool manually the script. Typically, testers, a combination of both. Use the recording mechanism to the basics of their skeleton to generate scripts and then manually change that reflect the scripts to the specialized scenarios. The load-testing tool, it should also allow the tester to simulate the limited range of situations. This means, for example, which would accurately model users who use the application on a slow modem connection would. He is also the testers to the script with random data from large amounts of data external drive.

Load testing scripts can either graphical or textual in nature. Good load and performance testing tools do not require testers to programmers. Testers who are not familiar with programming functions with scripts that can be manipulated graphically. Scripts graphics will usually have recorded all measurements in a hierarchical structure and testers do not change any measure to change the recorded script. Tester, the knowledge in programming may want to have to manipulate their scripts by editing the code. These testers were able to code in a programming language such as JavaScript, VBScript, or C written work known

Once the script has been created, you can to specialized controls. These controls would normally be specifically related to the application tested. For example, you can verify that the answer returned by a web request meets certain criteria, certain records. This would set up a checkpoint text. A text checkpoint to check whether a given text segment is present or absent in a particular part of the web page. When you are finished creating the script is usually to test the script on your own machine as an individual user to ensure that the test script works as expected.

You are now ready to load a test carried out based on performance. A good tool to test load, it will set the tester to perform the test. This means that it allows the tester to the number of virtual users simultaneously choose how the script on ramps, ramps and how it works as long. He is also the testers of the various groups of simultaneous users who create their own virtual ramp, steady state and ramp down characteristics. A good testing tool allows users to distribute the load to multiple machines from a single computer only able to scale up to several hundred users.

To understand the behavior of the web application is loaded, it is also important for the load-testing tool, so that the tester’s performance of the external components such as operating systems, web servers, databases, length, etc. This data allows the user to see how the performance of the application in connection with the performance of the external component. This type of analysis allows the tester to identify the cause of performance bottlenecks quickly.

During testing, the tester should be able to power curves for real-time performance indicators such as response time for transactions indicate HTTP responses per second through the HTTP code (eg groups 200, 404, 500, etc.), past transactions per second, non-transactions per second, total transactions per second, requests per second should, pages per second etc. The tester can also be downloaded at the same time shows the performance characteristics of the external components described. For an operating system that something like the% processor time could be, for a database could be the number of write operations per second. At the end of the test will indicate the tester is usually capable of, and store this data in a report for further analysis.

Load and performance, you can simulate the behavior of your application in a typical production environment. This allows you to plan your strategy for the efficient use of equipment and ensure that your application will provide the expected performance characteristics. Deploying a web application without testing its performance under production conditions should be similar loads crossing a road blindfolded. Load testing is an essential element of the development cycle of a Web application, and should never be neglected.

Development: This is the transformation of the design in a real application. The development phase usually consists of an architecture in which the underlying modules, which excluded the application are included. If symptoms persist data storage is required, a database schema should be to meet the needs of data storage. The choice of operating system (Windows, Linux or Solaris), where the Web application is running, the Web server (eg Microsoft IIS Apache, or Tomcat), the Web application, and opens to the back-end data base ( such as Microsoft SQL Server, Oracle, MySQL or Postgres) that stores the data should be made. Various development framework for creating Web applications. The most common are ASP and ASP.NET Microsoft, Java Servlets and JSP Sun, PHP and Perl that are open source. The choice of application framework is usually dictated by the forces of the members of the development team. The architecture phase is followed by the phase of implementation. This is usually the longest part of the project and during this phase, the code is written, developed using the specifications of design and graphic objects by the design team. The programming is usually done with a combination of frameworks mentioned above with HTML, JavaScript and CSS.

Quality Assurance and Testing: A surprising number think of people that quality assurance and testing is desirable but not really necessary. Unfortunately, this theory has its roots in complete ignorance of the process required to produce a finished good. Regardless of how pretty tablecloth or we ask if it does not work as expected, users will reject it. Quality assurance and testing involve two types of tasks. Functional testing and regression testing is used to ensure that the developed application does what it should do. This is achieved through test automation tool for functional tests. Load and performance testing is used to ensure that the application works as expected when the load exposed to a typical production environment. Load test is virtually impossible to achieve without the help of an automated load testing, as is the simulation of a large number of concurrent virtual users. This effect can not be carried out manually and really needs the help of an application that is specified for the intended application of the fee, and then measure the performance when this stress. Quality assurance teams will follow the bugs or errors in the application with the bug-tracking tools. These tools allow interference from all members of the team followed.

The above three categories tend to be specialized for their skills. For example, people often make the mistake of the developers use as a tester for quality assurance. This is not a sensible strategy, since most developers are good at writing software unfortunate enough to find errors or mistakes in their software.

Writing good and compelling Web applications, it must include all phases of the process, design, development and quality assurance. Skipping phases or cut corners will mean a low quality software, which are generally more expensive long term.

Network Interface Layer
The lowest layer of the TCP / IP. Its mission is to provide access to the physical transmission medium, and it differs depending on the application of the average.

Network Layer
The network layer provides network addressing, routing and transmission of datagrams. are protocols that interest on the DHCP are IP and ARP.

IP protocol
It is the fundamental protocol of the network layer, and in general the Internet as a whole. It sends datagrams, the independent units that contain information about the destination, are the source and sequence number of the datagram. The sequence number is used to reconstruct the message because the delivery of datagrams can not the same as their order in the message and delivery reliability is not guaranteed for all.

IP protocol versions:

“  IP v4 – 32 bit addresses. Provides approximately 4 billion unique addresses which aren’t sufficient at present times.

“  IP v6 – 128 bit addresses. The transition to v6 will bring (is bringing) higher security, QoS, packet segmentation and many more IP addresses. (the transition from IP v4 to IP v6 must be supported by the system provider)

ARP protocol
The ARP abbreviation stands for Address Resolution Protocol. This protocol is used to find the physical address (MAC) based on a known IP address. If required ARP sends information concerning the wanted address to all the stations in the network – Broadcast. The stations consequently answer with a message containing their MAC. If the wanted device/station is outside the node/segment, the appropriate router will answer instead of it.

Transport layer
The transport layer is implemented only in terminal devices and it adjusts the behavior of the network according to the requirements of the device/application.

Application layer
The application layer is composed of programs that use net services to fulfill the needs of users. Examples of specific protocols are for instance FTP, DNS and DHCP.

Application protocols use TCP, UDP or both services at the same time. So called ports are used to differentiate between application protocols, they represent a type of label of the application. It is possible to change the ports in the settings of the service, but each service has a default port that isn’t changed for most services and is used as an unwritten standard.

“  FTP = 21

“  DNS = 53

“  DHCP = 67 + 68
