Information concept

Information concept

                Data are the statistical facts which are not managed properly. The systematic framework of data is termed as information which is meaningful and which is so important in the organization.

We collect raw facts for various purposes and those collected data’s are needed to follow some certain procedures. They are: recording, classifying, sorting, calculating, and summarizing those collected data’s. There are certain types of data processing system and they are i) unit record method ii) Electronic data processing. Data are represented in the computer system in the format of 0 and 1.As we also have to understand about fundamentals of source coding. There are three types of source coding. They are: i) BCD (Binary Coded Decimal) ii) EBCDIC (Extended Binary Coded Decimal Interchange Code) iii) ASCII (American Standard Code for Information Interchange).BCD  is one of the early memory codes which is based on data of converting each digit  of a decimal number into binary equivalent rather than converting the entire decimal value into a pure binary form. EBCDIC is an 8 digit code which can be easily divided into two 4 bit groups. Each of these 4 bit groups can be represented by 1 hexadecimal digit. ASCII code has been adopted by different American computer manufacturers as their computer internal, code. Information concepts further tells about the data processing concepts.

They are i) Batch processing ii) Online processing iii) real time processing iv) Multiprocessing v) Multiprogramming vi) Time sharing concepts.

Data security

  Data security

 Data are the collection of raw facts which further processed can be meaningful information in the organization. They are the basic tools of the modern organizations without of which an organization cannot run smoothly and efficiently. By this challenging age, it is difficult to protect and secured data due to the unnecessary software’s and programs as well as the unauthorized personal handling of data. So proper care must be taken in order to keep alive of an organization. Mainly there are some techniques for data security.

i) We must use standard passwords which must be of 8 characters long, case sensitive, use of wildcards etc.

ii) We must create multiple backup copies of our data’s which must be kept at different locations.

i)                    We mustn’t have proper lock system of our room to deny the entry of unauthorized personnel and Hacker.

ii)                  We shouldn’t make the habit of keeping eye of entertainment websites which are the main source of accessing unnecessary software and viruses.

So we must be always careful of the various problems that might be seen while handling and securing the data of an organization.

C++

C++ is one of the most popular programming languages ever created^[4][5] and its application domains include systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games. Several groups provide both free and proprietary C++ compiler software, including the GNU Project, Microsoft, Intel and Embarcadero Technologies. C++ has greatly influenced many other popular programming languages, most notably C# and Java.

C++ provides more than 35 operators, covering basic arithmetic, bit manipulation, indirection, comparisons, logical operations and others. Almost all operators can be overloaded for user-defined types, with a few notable exceptions such as member access (. and .*). The rich set of overloadable operators is central to using C++ as a domain specific language. It is relatively difficult to write a good C++ parser with classic parsing algorithms such as LALR(1).^[18] This is partly because the C++ grammar is not LALR. Because of this, there are very few tools for analyzing or performing non-trivial transformations (e.g., refactoring) of existing code. One way to handle this difficulty is to choose a different syntax, such as Significantly Prettier and Easier C++ Syntax, which is LALR(1) parsable. More powerful parsers, such as GLR parsers, can be substantially simpler (though slower).

A++

A++ was developed in 2002 with the purpose to serve as a learning instrument rather than as a programming language used to solve practical problems. Dr. Barry came to this conclusion when taking suggestions from a local elemetary school where he often applied his technique.

It is supposed to be an efficient tool to become familiar with the core of programming and with programming patterns that can be applied in other languages needed to face the real world.

A++, with its interpreter available in Scheme, Java, C, C++ and Python, offers an ideal environment for basic training in programming, enforcing rigorous confrontation with the ess The purpose of A++ is not to be used as a programming language to write applications for the needs of the real world. Nevertheless it is possible to write simple application programs in A++ like object oriented implementations of a simple account handling and a library management system.

To write real world application programs the language ARS++ is provided, which extends A++ to a language similar to Scheme. ARS++ is derived from ARS plus Scheme plus Extensions.

Database

 Database

  Data are the statistical facts that are used to generate information. It is large in size and it hasn’t any specific meaning for decision making process. It needs certain process in sequential order to generate information from the data. Without data, decision makers cannot make appropriate decisions. Database is the systematic logical frame or format which helps to manage the statistical facts. With the help of the database it is easy t maintain the record, update it, manage it, manipulate it and secured it. A database is formed by the combination of different components like rows, columns, keys etc. It is always in tabulated format. Rows and column technically defines as record a field. Records explain details about the particular entity and a field explains the part of a whole facts. Its advantages are:

i)                    Database helps to integrate the scattered data or facts or figures.

ii)                   Database helps to reduce data redundancy and data inconsistency.

iii)                 Database provides the facility to browse the data from storage location either they are located at local area or remote area.

iv)                 It provides facility of data security.

v)                  It provides facility to record, update, manage,  manipulate and secured the data.

C Programming

  C programming

     C programming is the powerful, middle level programming language which can instruct low level operations of the computer. It is small and beautiful because its source code is compatible. Its capabilities can be extended by the programmers itself. C is modular programming language. And is system language for most operating system in programming language. Before the development of c, at first COBOL, BASIC, FORTRAN, PASCAL, CPL, BCPL and B programming language. But due to less powerful and efficient less features of those programming languages c programming language was introduced by Danice Ritchie and Ken Thompson at AT and T Bell laboratory, USA for PDP-11.

It consists of library files where definition of various keywords is declared so that those available 32 keywords can be easily used in any programming. The various terms used in c programming are keywords which are the reserved words in c programming language, variables which helps to store data on memory location and its value is not fixed, data type which helps to reserve the memory location on primary memory which includes simple data type (int, float, char) and structured data type (array, structure and union).
