How to Choose the Right Software for Your Business

A great majority of businesses in today are computerized. Software vendors are providing a wide range of features with customized business functions. Factors like cost, functionality, compatibility are different reduce. You have a number of options to choose to choose from as per the need of your business. But it is not good to buy blindly. If the purchased software creates issue, the entire business process or particular department will stuck.

Here are steps to follow before you buy software for your business. They help you minimize the common mistakes.

• Internal need analysis: First, know what sort of software your business needs. List requirements with the software. It makes a clear picture to explore the best software vendor. If it is a custom made software, the list will give a clear picture to the developer company.

• Customer service team is also an important to check. Does the team is responsible and knowledgeable?
• Consider both positive and negative opinions.
• Hidden and additional charges by the vendors.
• Customization and scalability of the software for future development of business.
• Who maintains the data? which is entering through the software
• See for security issues.
• Check the software license type.

• Take test drive: Most software as a service (SaaS) vendors agree for a demonstration version to test drive. Take the software application(s) after screened. Check the features and functionality available in the software. Do not give the commitment in the beginning to any software vendor.

• Made final choice: After the test drive, pick the perfectly suitable solution for the business. Thoroughly check the license terms and conditions, the support providing by the vendor. Agree to the key performance indicators.

Choosing the right software for your business is important, because it avoids the shortage or surplus of resources and helps you reduce the time to operate, and the inefficiency in operations of your business. In the long run, it helps your business thus, increase productivity, and revenues.

Working of Websevers and Different Types of Web servers

Web servers serve its clients with the requested web pages using Hyper Text Transfer Protocol (HTTP). HTTP in simple terms, is the language in which the client and server communicate. This article explains how web servers actually works and also discuss different types of web servers that are available and help users choose the best suitable one for their use.

Working of web server

• User first requests for the web page by typing URL in web browser.
• The Web browser receives the URL and converts into machine readable format. The URL is converted into IP address.
• The Web browser checks if it has already the location of that IP address. If not, it sends the request to DNS server for help find the location of the IP address. DNS server then tells the browser the actual location of that IP address.
• IP address of a website is generated during the creation of website.
• Then the Web server will fetch the required web page that user wants, and sends it to the browser.
• Browser receives it and converts it into user readable format and displays it to the user.

Different types of web servers

There are three types of web servers. They differ in the performance and specifications. Costs of these three different web servers are also different. The three different web servers are

Dedicated servers

• Dedicated servers are the servers that are owned by an individual user or an organization.
• All the hardware and software resources of the server is configured by the owner according to their needs.
• All the resources are used exclusively by that individual/organization only.
• Installing, upgrading or removal of any software application is up to the owner and he can do as his wish.
• Security to the data or confidential information is high because no access to the unauthorized users.
• Dedicated servers are suitable for the large businesses with big databases.
• Dedicated servers are the most expensive servers of all three types of web servers.

Shared servers

• It is a single physical server that is shared among many users. Hence, the name "shared server".
• All the hardware resources are shared among all the users of the server.
• As many websites/users uses the same server, if at any time, any website becomes busy, then the performance of the server decreases, and it affects all the websites sharing the server.
• This is the cheapest server of all three kinds of web servers.
• Shared server is suitable for the small businesses or individuals.

Virtual private servers

• Virtual private servers are similar to servers that are shared. The difference is the restriction of number of users on the virtual private servers. It does not allow too many users.
• Other websites/users are affected if any of the users, sharing the same virtual private server uses most of the resources.
• This is suitable for small and medium sized businesses.

Understanding how web servers work and the three different types of web servers, businesses or individual users can choose the best web server suitable for them depending on the size of the business, requirements and budget.

How Does SMS Advertising Software Works

SMS advertising software is developed for the purpose to send and receive messages from PC to mobile. SMS gateway is a message transmission between the world wide web and mobile. This software allows the user to send bulk SMS to the mobile users with the help of software database. The SMS advertising software is offered by many SMS software providers. Business persons buy the SMS advertising software from the SMS software providers.

The software provider give a short or long unique symbol code to the buyer. After the software is bought, the business persons first prepare mobile number database of individuals. Then the database is uploaded to the software. After this procedure, the business person prepares his SMS ad in any one of the languages and sends it to the database. While sending it to the database you need to choose the particular group of numbers to which you want to send SMS. After it is sent to the database, the database filters the numbers according to your need. Then the message and the recipient numbers are send to the SMS gateway provider server.

The server sends this message and recipient number code to the short message service center (SMCS). The SMCS is an entity of a mobile station modem, which is fixed at one mobile station (usually it is SIM provider station). This SMCS send the recipient number code to the GMSC (gateway mobile station center). This GMSC send unique code to HLR (home location register). The home location register has all the mobile users registration form details. It gives the recipient network location to the mobile station center. Then the center sends message and the visitor code to the visitor location network(VLR). Finally the VLR conforms the visitor number and the message to the recipient mobile.

It is in a simple manner represented in the form of a flow chart
Business software database → SMS software provider server → short message service center → home location register (registration form details database) → current network location center → mobile.

Know About Software Security Assurance

Software security assurance is a process that helps in designing and implementing software and also helps in protecting the data and resources contained and controlled by the software. First step in the software security assurance is identifying and categorizing the information that is to be contained in, or used by the software. Based on the sensitivity, the information is categorized. After categorizing the information, the security can be developed. These security requirements should solve the problems regarding the access control, environmental control, human resource security, audit trails and usage records.

The security problems occur in the software because of security bugs with in the software. These defects are caused because of two reasons, one is failure to satisfy requirements and the other is an error in the software retirements. There are two types of software security assurance activities, first one ensures information processed by an information system is assigned a proper sensitivity category and the other focuses on ensuring the control and protection of the software and software support tools, data. There are many tools used in software security assurance and before going to purchase the software packages that support software security assurance activities, it is better to evaluate these tools and their effectiveness must be assured.

Security architecture verifies the design of the software and correctly implements the security requirements. Software security assurance is a holistic approach to software development and its main aim is to make critical business software more secure. It is implemented by leading security practitioners, businesses, and government organizations.

Software Standard and Its uses

Software standard is a standard protocol of a document, file or data transfer used by many software developers working on one or more different software programs. Software standards are used to coordinate different programs which are created by different program developers. There are some software standard organizations whose standard should be agreed by software companies to make software connect each other. Complexity of the standard also depends on the problem to be solved.

There are two types of standards, one is open standard which is open to public, and the other is closed standard, which is not available for the public, but enables its developer to sell and license the code to manage their data format to other interested software developers.

Uses of software standards are:

• Software standards consist of certain terms, data formats, concepts, document styles and techniques which helps a software creator to develop a software that understand the files and data created by a different software program.
• Software standard provides efficiencies for the development of codes, wider user acceptance and use of the resulting application.

Some data formats are widely used and understood by the software programs, like, MS Office file formats, such as .doc and .xls which can be converted and understood by other software programs, but they cannot be considered as the standard because they are owned and controlled by Microsoft.

Use of Software for Web-development

Application of software can be helpful for web-development. Software is used for creation and development of websites. There has been a lot of importance for web-development. Many online auction sites and online resellers are available today. Web development is very essential for them.

Various technologies such as Java, JavaScript, Flash, and others can be used for development. These can be used for applications such as drawing on the screen, playing audio, and access to keyboard and mouse. HTML editor is one of the applications of software for creating web pages. Many application software companies provide web access to software that was distributed as local applications.

The work involved in developing a website for the internet or an intranet is considered as web development. Web design, web content development, client-side/server-side scripting, web server and e-commerce development are included in web development. The work involves http://www.blogger.com/img/blank.gifwebmasters, graphic designers, and information systems technicians. Many areas are included in web development that include client side coding, server side coding, database technology and security considerations. Application of XAML and .Net programming languages is done in Microsoft Silverlight which enables animation, vector graphics and high-definition video playback. Many software engineering principles are used by the web-applications.

Database technologies such as Oracle, MySQL, Sybase, and others can be applied for web-development. Many security considerations such as data entry errors, filtering output, and encryption are important for web development. Some of the applications of Perl, PHP, and ASP are used in security consideration.
