Understanding The Term Data Processing Information Technology Essay

Understanding The Term Data treat Information Technology EssayData affect is any computing device process that converts entropy into instruction or knowledge. The processing is usually fictive to be automated and running on a computer. Because information atomic number 18 most useful when well-presented and actually informative, selective information-processing systems atomic number 18 often referred to as information systems to emphasize their practicality. Nevertheless, both terms are roughly synonymous, fulfilling uniform conversions data-processing systems typically manipulate raw data into information.Information Information is data that has been processed for use.Relationship between data processing and information in a computer systemWhen information is entered into and stored in a computer, it is more often than not referred to as data. After processing (such as formatting and printing), output data can again be perceived as information. Data processing is the actual process of converting the information into data and vice versa in a computer system.2 Distinguish between data and informationdata is what is entered into and stored in a computer after the data has been processed it is called information.3 why are digital computer useful in data processingA digital computer is the main mechanism utilize for transforming data in data processing.4. Describe in detail the corporal security, the social environment under which the computer performs shell.Computer perform best in a cool and clean environment as diddley and heat affect the performance of a computer system contribution B (COMPUTER PROGRAM)I. Distinguish between low level language and spirited level language.The main difference of upper-level languages and low-level languages is that high-level languages are easier to read, write, and maintain. Ultimately, programs write in a high-level language must be translated into apparatus language by a compiler or interpreter.II. apol ogise the acronymsCOBOL Acronym for common business oriented language. Developed in the late mid-fifties and early 1960s,. It is specificly popular for business applications that run on openhanded computers. COBOL is hush up the most widely used programing language in the world.FORTRAN Acronym for formula translator,. Designed by John Backus for IBM in the late 1950s, it is still popular today, particularly for scientific applications that require extensive mathematical computations. rudimentary Acronym for Beginners All- blueprint Symbolic Instruction Code. staple is genius of the earliest and simplest high-level programming languages.Despite its simplicity, BASIC is used for a wide liberal of business applications. There is an ANSI warning for the BASIC language, but most versions of BASIC include many proprietary extensions. Microsofts popular Visual Basic, for example, adds many object-oriented features to the standard BASIC.ALGOL ALGOL (short for ALGOrithmic diction)1 the de facto way algorithms were described in text-books and academic works for nigh the next 30 years.These languages are best suited for text establish data processing.III Mention and explain three special intend high level language.1 Ruby is a dynamic, reflective, general purpose object-oriented programming language.Ruby supports multiple programming paradigms (including functional, object oriented and imperative), and features a dynamic type system and automatic memory management.2 Perl is a dynamic programming language created by Larry Wall and first released in 1987. Perl borrows features from a variety of other languages including C, shell scripting (sh), AWK, sed and Lisp.1 Perl was widely adopted for its strengths in text processing and lack of the arbitrary limitations of many scripting languages at the time.23 Python is a general-purpose, high-level programming language. Its design philosophy emphasizes programmer productivity and decree readability.2 Pythons core s yntax and semantics are minimalist, while the standard subroutine library is large and comprehensive.Python supports multiple programming paradigms (primarily functional, object oriented and imperative), and features a fully dynamic type system and automatic memory management it is therefrom similar to Perl, Ruby, Scheme, and Tcl.IV. What is a language processor and why are they inevitableA hardware device designed or used to perform tasks, such as processing program code to machine code. Language processors are found in languages such as Fortran and COBOL . They are requirement because they are used to convert your program code to machine codeV. what is the difference between a compiler and interpreter?Compiler leadtranslate the sourcecode written in some kind of programming language, and then ultimately translates it into object code or machine language whileThe interpreter translates instructions one at a time, and then executes those instructions immediately. The compiler is itself a computer program written usually in some implementation language.SECTION C(DBM)Define the next1. FieldA field is a space allocated for a particular item of information. A tax form, for example, contains a number of palm one for your name, one for your Social Security number, one for your income, and so on. In database systems, fields are the smallest units of information you can access. In spreadsheets, fields are called cells. roughly fields have certain attributes associated with them. For example, some fields are numerical whereas others are textual, some are long, while others are short. In addition, all field has a name, called the field name.2. RecordRecords are composed of fields, individually of which contains one item of information. A set of records constitutes a file. For example, a effect file might contain records that have three fields a name field, an address field, and a phone number field.Some programming languages allow you to define a special dat a structure called a record. Generally, a record is a combination of other data objects. For example, a record might contain three integers, a floating-point number, and a instance string.3. FileA file is a collection of data or information that has a name, called the filename. Almost all information stored in a computer must be in a file. There are many different types of files data files, text files , program files, directory files, and so on. polar types of files store different types of information. For example, program files store programs, whereas text files store text.4. eccentric personShort for binary digit, it is the smallest unit of information on a machine. A single bit can hold only one of twain values 0 or 1. More meaningful information is obtained by combining unbent bits into larger units. For example, a byte is composed of 8 consecutive bits.5.CharacterA character is any symbol that requires one byte of storage. This includes all the ASCII and all-embracing AS CII characters, including the space character the term character is generally reserved for letters, numbers, and punctuation.(ii) invest three file organisation method known to you and state their chastity and demerit.
