How to Program a Symbol LS2208 Barcode Scanner

The Symbol LS2208 scanner is a very popular, lightweight, ergonomically designed barcode scanner used in conjunction with many Point of Sale (POS) software.  However, prior to using the scanner with POS software there may be some very simple programming steps that will need to be take to get the scanner ready for operation.

One of the first steps to programming a Symbol Scanner is to program the type of interface that you will be using with the scanner.  If you are using USB or Keyboard Wedge interfaces, you don’t need to worry about programming the scanner as the scanners come pre-programmed to use these interfaces.

If you are going to be using the RS-232 or the IBM 46XX interfaces there is a very simple step you must follow to program the Scanner.  In the LS2208 Quick Start Guide, under STEP 3 you will have to scan the appropriate barcode for either an OPOS/JPOS or a Standard RS-232 interface.  Simply by pointing the scanner at the appropriate barcode and scanning it, you will be programming the scanner to use that interface.  The Quick Start Guide also has barcodes you can scan for the PORT 5B or PORT 9B – IBM 46XX interfaces or to switch back to USB or Keyboard Wedge mode.

Once you have the interface programmed, the next thing you will need to program is the enter key, carriage return/line feed function.  This function programs the scanner to append a carriage return/line feed character to be sent to the computer at the end of each barcode that is scanned.  This will eliminate the need for your cashiers to have to hit enter after scanning a barcode in their POS system.

To program the enter key, carriage return/line feed functionality into the scanner all you need to do is simply scan the three barcodes found in the Quick Start Guide.  There is also the option of appending a tab key to the end of a barcode scan in the manual as well, and is performed the exact same way as programming the enter key.…

Advantages Of Java Programming In Software Industry

The modern history of computers was set to change forever when in 1995 James Gosling of Sun Micro systems unveiled Java to the world. Since then, there has been no turning back and Java is the most popular programming language preferred by programmers the world over. It is used to design software as well as a host of other web applications.

Like most programming languages it is constantly evolving and the language has been tweaked a lot over the past fifteen years to smoother it out as well as improve its efficiency. Even though Java has a totally different purpose it can very easily be compared to PHP which was also released in the same year. While PHP is used to design innovative websites, it is an open source language just like Java which means it is freely available to the public at large.

The advantages of the Java programming language are many but what can be more important than the fact that it is simple to understand and for budding java programmers in the virtual world it is a dream comes true. The task of writing and compiling in Java can safely be called lucid and it creates such groundbreaking software applications that it easily found its way into a serious computer user’s life.

Another point worthy of mention is that Java can perform on any platform without any glitches. Be it Windows or Linux, the Java language will give you the same result irrespective of the operating system. Not all languages can boast of such an innovative feature.

In today’s age where Wiki Leaks has opened up a Pandora’s Box, the Java language has been put together keeping security as the topmost priority. When the Java language is being utilized one can work in a secure environment so that no viruses can attack the host system.

A general overview of Java sets it apart from the other languages out there. Not only is it dependable (it was created after omitting a host of initial errors) but it also supports multi-thread programming thus assisting software developers to make applications with many levels. The Java language on a whole is highly progressive: the code is stored in units known as classes which are fed to a Java interpreter only when required.

The bottom-line of this pioneering language is its versatility, simplicity and overall error-free running. Since it was brought out, Java has given the web world a host of software which have been used in diverse fields. Giant leaps have been made with this language and many pundits have compared Java with Clarion.

However, Java seems to have come out on top for the simple reason that you can write whatever you want with this language. The entire gamut of Java codes is just mind-boggling to comprehend and the scope for further maturation of this language is bright.…

10 Reasons Why C is the Best Programming Language For Beginners

With the plethora of programming languages these days, and the massive programming information available in the Internet, it can be difficult for a beginner like you to know where to start. When it comes to programming language for beginners, C is an excellent choice. Not only will it educate you of programming fundamentals, this language is also powerful and is widely used in the industry today.

Here are the reasons why C is a great programming language to begin with:

1.    You can’t learn Java or C directly.

For you to learn and master C and Java languages, you should have a rock-solid concept of the elements of programming like classes, polymorphism, inheritance, and others. Come to think about it, how will you learn complicated concepts like these if you are not even familiar with the basic elements of computer programming? The language that starts from scratch is C and its foundational concepts are the basis of any other programming concepts we have these days.

2.    It is the basis of C , C#, and Java.

C and C# are programming languages based on C. Java also derives its syntax and programming concept from C. This is known as the world’s most dominant programming language and it is also derived from C language.

3.    Programs that need Object Oriented Programming (OOP) are written in C.

Java, C#, and C employ OOP. Despite being powerful, not all programs use it and those utilizing it are still written in C.

4.    C boasts unbeatable performance.

When it comes to speed of execution, C is still unmatched.

5.    Most parts of Linux, Windows, and Unix are written in C.

So if you want to program these OS, or if you wish to have your programs run in the said operating systems, better be familiar with C.

6.    Drivers of modern gadgets are written in C.

Why is this so? Well simply because C gives users access to the computer’s basic elements. It also provides you with direct access to your CPU’s memory by means of pointers. You can also use C to control bits and bytes.

7.    Mobile phones, PDAs, palmtops and other handheld devices as well as appliance are becoming more popular than ever.

You may not be aware of it, but your handheld devices and home appliances may contain CPU that requires programming and has software dubbed as embedded system programs.

8.    Most PC games employ C as their foundation.

No one will be interested in games if it takes too much time for commands to be done. C is used to make things fast and prompt.

9.    C is considered as mid-level language.

Programming languages are categorized into three – Low Level, Middle Level, and High Level. Aside from being user-oriented, high level languages also make development of programs fast enough. Machine oriented, low level languages execute programs faster. Middle level languages like C combines the best attributes of the high and low level languages.

10.     C is a block-structured …

The Future of Object Oriented Programming

The object-oriented paradigm is based on the idea that objects exist independently of each other, and that operations can be executed on them. Consequently, a user in a true object-oriented development environment should be able to interactively create objects of any available class, manipulate these objects and call their interface routines.· Platform independence – “Write once – run anywhere” capability

As a matter of fact you cannot run a java program ‘anywhere’ unless there is a virtual machine. But its as good as anywhere. Also I know some folks who would say its “write once debug everywhere” but any such platform dependent bugs are probably VM issues. All in all this platform independence is a huge plus point for enterprise development saving tons of cash and effort in porting products.

· Ease of use

I’m not really sure how many hard nut programmers would agree with me but programs are easy to visualize when they are object oriented (once you get the hang of it). After the concept is built, it becomes much easier to realize it in code.

· Free runtime/compilers/tools

This was one of the best moves by Sun. The runtime is free, the development kit is free and now there are a ton of other tools built with java for java that are free. This makes java development easy and affordable.

There are a number of ways to measure the popularity of a programming language, for example, based on the number of:

  • New applications written in the language
  • Existing applications written in the language
  • Developers that use the language primarily
  • Developers that use the language ever
  • Web searches
  • Available jobs that require skills in the language
  • Developers’ favorites

Java has some other advantages as a teaching language

Low cost. The tools needed to build and test Java programs

are available without charge. Sun makes the Java Development Kit (JDK) available over the Internet, where faculty and students alike can download it. The JDK-which includes the Java compiler and interpreter, among other tools-is admittedly spartan, but students should find it adequate for most programming assignments. Those willing to spend a little money will find nicer program development environments (such as Symantec Café and Microsoft J++) available at moderate prices.

Easy to test. Students can put their programs-written as applets-on their Web pages for instructors to test and critique. Instructors can monitor a student’s progress at any stage by simply visiting the student’s Web page.

Student enthusiasm. Java has gotten so much publicity

that students are bound to be excited about learning it. By harnessing that enthusiasm, instructors can use Java as a vehicle to teach students a tremendous amount about modern-day computing. Students will be motivated by Java’s growing importance in the “real world.” Moreover, students will be thrilled by the ease with which they can build sophisticated GUI programs.

Suitable for advanced courses. After students gain

familiarity with the basic features of Java in CS1, they can use its advanced …

Importance of Back-End Web Development

While creating a new website, developers have to focus on both frontend and backend development. The frontend of an application refers to the code that is visible to the website visitors. Normally, frontend code creates interfaces through which the application interacts with the users. On the other hand, the backend code interacts with the server, and delivers content or data to be displayed to the users. So the backend code deals with the application as well as the web server and database. The combination of application, server and database makes the backend coding both complex and important.

Why Developers Must Pay More Attention to Backend Web Development?

Facilitates Information Exchange

As noted earlier, backend consists of three key elements of a website, i.e., application, web server and database. While accessing the user interface of a website, each user is required to provide his login id and password. The login id and password provided by the user is validated by the backend. Likewise, any information submitted by the user is stored in the databases through the backend code. Also, the backend retrieves information from the database, and sends the information to the user interface for displaying to the user. Hence, the backend of a website acts as its structure and facilitate information exchange.

Runs in Various Environments

Nowadays, businesses deploy websites and web applications in a number of environments. For instance, some enterprises prefer running websites on web servers, while others deploy web applications in the cloud. At the same time, many businesses even combine both hosting options to avail benefits like enhanced performance and scalability. The web server setup varies from one network to another. Also, the programmers often distribute server-side workload over multiple machines. The varying hosting environments make it essential for developers to customize the backend of websites.

Contains the Application Logic

Most programmers nowadays keep the user interface and application logic of a website separate to simplify its development and maintenance. In addition to including the domain and infrastructure components of an application, the application logic also performs the routine data processing required by each business. The backend of a website contains its application logic. Hence, the developers must focus on backend web development to switch from one frontend to another seamlessly, and make multiple user interfaces access the same application logic.

Adds Utility to Each Frontend Functionality

While developing a website, programmers are required to write backend code to add utility to each frontend functionality. For instance, they have to write code using a server-side programming language to add functionality to a user login form. Each time a user enters his login credentials, the backend code will collect the values, and compare them with the login data stored in databases. Likewise, backend code also adds functionality to various forms, profiles and accounts. Hence, no website can function without quality backend code.

Impacts the Website’s User Experience

The usability and user experience of a website impacts its popularity in the longer run. As noted earlier, all tasks …

Properties Of A Good Computer Program

A program can be termed as a set of instructions that help in running things. For a computer to perform certain required tasks, it requires an appropriate program. When correct instructions are fed to the computer, then its performance will at most times be at optimum, whereas the opposite is likely to mess things up.

Today many businesses require computers to ensure smooth running of business. Therefore, the computers should have programs that are user friendly and easy to understand. A few things will tell if a program is good enough.

Is it readable

If the program is in writing that makes it easy for a user to understand and follow the logic, then it can be termed as good. It should also have a systematic arrangement that will make it easier to troubleshoot the computer if anything goes wrong.

Efficiency

Your program should save you time. For you to process instructions you will need time and will certainly use up some memory. A good programming is that which works with less processing time and a small amount of memory. This proves efficient as you realize less waste.

Flexibility

A good program should be able to accommodate different platforms, without having to make major changes to coding and software. It is common phenomenon today to see different platform changes.

Therefore, having a portable program will not be affected if the user decides to change the operating system. When good computer programming is done, your system is able to handle modification, which happens due to many reasons like change of administration.

It should only have simple codes that facilitate different amendments needed over time.

Proper structure

For a program to be developed, the major tasks that are required to run the different systems should be broken down. A developer can also develop them independently in order to accomplish the job assigned to them without having to rely on other subtasks.

Proper documentation

Every program has to have good documentation especially if the author will not be around for long. This is so that the other person handling it will find it easy to comprehend.

Many people make computer programming their career. These are the best people to get good programs from. Having a reliable source for the program will give you the satisfaction that the vendor will be there in case any concerns arise. Having one specialist like this in your business especially in the IT department will ensure that your systems run efficiently.…

Basics and Criteria for Good Software Programming

A program is a set of instructions or commands to be executed by the computer to accomplish some task. A program involves code for solving a problem and also good documentation which would be a guideline to anyone who tries to understand the program.

An algorithm is a formula, a method, a recipe, a step by step procedure to be followed in order to obtain the solution to a problem.

Conversion of an algorithm to a program in a programming language following the syntax and semantics of that language is defined as a code.

Syntax is the correct method or grammar of writing a command or series of commands which are pre-defines by that particular programming language. Semantics is the logical meaning of a program or series of commands, separate from the grammatical structure. The computer detects syntax errors but does not detect logical errors.

What are the Criteria for a good program?

  • It should be correct i.e. output should be as per the specifications
  • It should be reliable; it should function accurately for a long period of time and also function correctly over all ranges and combination of data.
  • It should be robust; unwanted inputs or data should be identified and proper error message should be flashed. It should never crash.
  • It should be user friendly with enough comments, tips, on-line help and short cut options.
  • It should be efficient, with minimum memory and quality output in acceptable time span.
  • It should be readable i.e. it should be simple so that it can be understood to make changes and enhance it if required.
  • It should be portable so that program can be executed on different machines and environment.
  • It should follow all standards and have proper documentation.
