    A proxy server acts as a connector between two networks. One network is the internet and the other network is a series of system that are connected within themselves.

    The primary reason for using a proxy server is to hide system identity from other systems on the internet. Internet cafes make use of proxy servers for the purpose of managing payment for internet access. People who are under oppressive regimes make use of proxy servers to spread their political opinions. Using a proxy server also increases the speed of internet access in some cases.

    There are many types of proxy servers and you can choose one depending on your requirement. The most basic type of proxy server is the simple proxy server. This is a very basic proxy server type and it receives request from the client computer and sends the request for access to that internet resource. It then returns response from the client back to the internet resource.

    Another type of proxy server is the reverse proxy. This proxy server receives requests from various systems connected to the internet and connects it to a group of internet servers.

    If the internet connection is slow, a caching proxy server is used. This server saves a copy of all fetched content and used that copy whenever new content has to be fetched. These types of servers are used in fast connection environment for the purpose of saving bandwidth cost.

    There is a need for restricting internet access so that content filtering proxy servers enable filtering of content during the process of internet access. This type of server is used by schools to block objectionable sites and in some cases companies to restrict job sites, porn websites and even social networking websites. The network administrator can set those sites that can be viewed and block sites that should be avoided.

    In small business computer consulting, $100 an hour can be a reasonable and livable rate. Why can setting your rates at $100 an hour make all the difference in the world?

    Take the $100 an hour and multiply it by 1,500 hours a year. This is reflecting a 75% utilization rate; or 75% of a typical forty hour work week as billable time. Now youre at $150,000 a year gross.

    Salary and Affordability

    As a small business computer consulting firm, you will want to take a third of the gross and plow it into sales and marketing. Therefore you can afford a $40,000 base salary for your sales account executive. So, of that one third of your gross small business computer consulting income, $40,000 can go to the base salary and $10,000 can go to related marketing expenses.

    Additionally, one third will take care of taxes, insurance and overhead items for the most part, and you have a third of it or $50,000 left to pay a technical staff salary.

    Surpassing $100 an Hour

    You may be considering exceeding a rate of $100 an hour for your small business computer consulting firm. At that point, you can hit what we call the not-so-imaginary-hourly-billing-rate ceiling.

    Needless to say, if your small business computer consulting clients are paying $110 to $125 an hour, it gets even easier to be able to afford really bright, motivated, highly qualified sales and technical staff.

    Higher Rates Equal Bigger Businesses

    However, if you want to charge above $100 an hour in your small business computer consulting firm, youll almost always need to move above and beyond sweet spot small business clients into really large small businesses, medium size businesses and enterprise-sized accounts that require a different business model and technical skill set.

    Once you do that, youre going to be operating under a completely different type of business model. And you will need even more polished and seasoned salespeople to be able to handle those accounts.

    Hello Friends,
    In this series of post, we’ll learn about Descriptive programming (DP).

    There are two ways, QTP uses to recognize the objects present in your application.

    1. Object Repository (OR)
    2. Descriptive Programming (DP)

    First let see how OR works. OR is the simple and default way of object identification in QTP. OR stores groups of properties and values of every object. While you record on application, all the objects you click, are stored in Object Repository.

    During the play back QTP use this OR to identify the object on which the action is to be performed.

    What is Descriptive programming (DP)?

    We’ll use DP when we want to bypass OR. Descriptive programming is used when we want to perform an operation on an object that is not stored in the object repository. This way QTP wont search for the object properties in the OR, but will take it from the DP statement.

    Why use Descriptive programming (DP)?

    Everything looks fine while automating test using OR then why should I use DP?

    Well, there might be many valid reason to do so. Think about a situation – you want to close all opened browser automatically before you start executing your script. Here OR will not help you to identify an object as it is not possible to store all the opened browser objects into OR. Make sense?

    No worries! We’ll discuss the need and benefits of DP in detail later in this post. Well examine scenarios where ORs advantages are outweighed by the DP.

    I am not very good in vbscript. Is it mandetory to learn vbscript explicitly to write DP?

    No. Not at all! Its not mandetory, but yeah.. recommended. For basic opretions and starting with DP, this post will guide you.
    Although, for advanced oprations i.e. using COM, AOM, complex framworks etc. vbscript knowledge is the key.

    Okie guys! Now, lets start writing DP!

    Writing Descriptive Programming (DP):

    DP can be written in two ways..

    1. Static (by provide the set of properties and values directly)
    2. Dynamic (by creating description object)

    Static:

    – In Static method of DP, we provide the set of properties and values directly in a single line, in form of the string arguments.

    Here is the format/syntax of DP..
    object’s Class Name(“property name:=property value)
    Exmp 1: webbutton(Name:=Google Search)

    object’s Class Name = webbutton
    property name = Name
    property value = Google Search

    Exmp 2:- Browser(google).page(google).webbutton(name:=Google Search,type:= Submit).click

    In above statement, Browser(google) and page(google) are written using OR. And webbutton(name:=Google Search,type:= Submit) is written using DP. Please note that we can write multiple set of properties and values in any DP statement.

    Examples:
    webbutton(name:=Google Search).click

    Among the topics of interest for students who wish to create zoology science fair projects those that involve ants are the ones most students will choose. A zoology science fair project will demonstrate the knowledge that students have learned regarding some particular type of animal. Ants hold a great fascination for children and adults alike. These amazing little creatures are communal and depend on each other for survival. Very seldom do we see a single ant. This type of living system makes ants a favorite topic for zoology science fair projects. Students can choose any number of subjects related to ants or any other animal to study for their zoology science fair projects.

    One of the most interesting subjects that students study using ant populations is in the area of food choice. While most people are familiar with ants as uninvited guests at picnics, most people know very little about these tiny creatures. A zoology science fair project will use different foods to see which flavors, if any, the ants prefer. Students will conduct experiments and collect the data from these experiments in order to make a presentation for the zoology science fair projects. This data will then be used to compare different types of foods. It could then be used in supplemental studies to compare the flavor choices of different types of ants. These little creatures are more than willing to participate in these types of experiments because all that is required of them is that they eat!

    Zoology science fair projects can also be performed on microorganisms such as bacteria. The zoology science fair projects can also be based on the osmosis and diffusion that is present in living cells. These types of zoology science fair projects are particularly suited to computer-generated presentations. Since these organisms and processes are too small for the human eye to see, students often have a difficult time grasping the concepts. Zoology science fair projects are a great way to demonstrate these types of scientific phenomenon. The presentations bring to life all the tiny components involved in the life experiences of living creatures. These and many other topics, such as the study of environmental changes for marine life, the effects of chemicals on animals, and how different conditions affect growth rates, can be explored with zoology science fair projects.

    Voice over Internet protocol (VoIP) technology has become standard in many offices and storefronts. It provides higher bandwidth and better capabilities than traditional phone lines. Faxing has changed because of the introduction of VoIP technology. Traditional fax machines that used modulated sound to transmit data are being replaced by software-based digital systems. Small businesses can benefit in a number of ways by switching to fax over IP technology.

    Reliability

    One of the ways fax over IP can help a small business is by improving the reliability of transmissions. Traditional faxes rely on signal modulation to send and receive data. Inconsistencies in the telephone lines, minor hardware issues and even different fax machines can cause these transmissions to fail or to become corrupted. The fax over IP technology is digital and the data has a very low to non-existent chance of loss. This makes digital faxes far more reliable.

    Lower Costs

    Fax over VoIP will save small businesses money over traditional faxing technologies. VoIP protocols can be sent across any network line. They can also be interpreted by a wide range of technologies from computers to multifunction printers and even mobile devices. This makes it unnecessary to maintain dedicated phone lines. It also decouples faxing from older fax machines that require constant maintenance, paper and toner.

    Environmentally Friendly

    Sending fax over VOIP in a network through a line can be done completely electronically. Small businesses do not need to feed a paper printout of an invoice or report into a machine. Similarly, faxes that have been received do not need to be printed immediately or at all. Sending and receiving faxes can be done through a software interface. Faxes can be sent and received as digital files that are viewed on computer screens or mobile devices. This allows a small business to be more environmentally friendly without having to sacrifice the convenience of faxing.

    Better Access for Employees

    The traditional way of sending faxes involved loading a machine, dialing a number and then waiting for a confirmation. This is time consuming and inefficient especially when multiple people need to send a fax. Fax over IP technology makes it possible for employees to send faxes seamlessly from a desktop or other device. The fax can be added as a network device similar to a printer. Employees can simply send documents to the fax from within different programs.

    Higher Quality Faxes

    A large benefit for modern businesses is higher quality faxes. Fax over IP can encode documents created digitally. There are no scanning or resolution issues. People who receive the fax will see the document exactly as it was created. This can make it easier to send documents that include detailed charts, small graphics or complex illustrations. The individual pixel will not run together and become illegible because of issues with an optical scanner at the last minute.
