= How do you distinguish between data and information? = I THOUGHT DATA WAS THE OFFSPRING OF IMFORMATION, CONSIDERING DATA WOULD BE THE GATHERING OF INFORMATION. IT COULD SAID BE LIKE THIS: ALL THE INFORMATION YOU REQUESTED DATA ON HAS BEEN STORED IN YOUR HARD DRIVE, THEIR THE TWO TOGETHER IN ONE SETENCE. ON THE OTHER HAND DATA.. INDUCTIVE REASONING: A TREMENDOUS SEA OF INFORMATION.. YOU HAVE TO SEE ENOUGH, TO REMEMBER ENOUGH INFO TO PUT IT TOGETHER. I SAID THAT.... GENA

Professordata is a contrast is a collection of facts ,figures and observation or events ,resresented in the form of symbols such as digits,alphabets, pictures and so on .it is a basic raw material in the process of the generation of information. it is a stream of raw facts representing events occuring in an organisation before they have been organised and arranged in a form that people can understand and use
.it can be collected from internal sources as well as external sources.
data is like raw materials have been processed in a systematic way.
information: information is data that has been put into meaningful and
useful context. it is a set of facts , which reduces uncertainty and makes more sense to the user than just plain data information has value in decision- making while data does not have such meaning within a specific context. according to the classic information systems definition,information is knowledge drived from data .in this a clear distinction is the amount of uncertainty that is reduced when a data recieved.davis olson have suggested the following definition of information ."information is data that has been processed into the form that is meaningful to the recipient and is having real perceived value in current or prospective decision". information consists of data that has been retrieved , processed and which can used for the informative purposes for forecasting or decision-making.
Data is the collection of raw facts and figures whereas information is the useful result or inference etc. obtained after processing some data. In other words processed data is called information. For example the observations obtained in the physics lab is the DATA and the result obtained after going through that data is the INFORMATION.

What are characteristics of an information system that lead to it having one database and many application processes?
1. The Organization of data into information For data to be made meaningful it must have a purpose. The purpose of the stored data should reflect the purpose and type of the information system. Data needs to be processed and organised before it becomes information. Organising the data will most likely involve the processes of sorting and filtering (classifying) before it can be analysed and stored for later retrieval. Data dictionaries are used to help organise the data. 2. Ability to Analyse the Information Once the data has become information it needs to be analyzed to make the most of the information stored. Analysis of databases is done through the tools of queries and reports. You can find answer in the net.... like i did....XD
Show the data processing cycle?
The data processing cycle is the process of converting data into useful information. The data is processed again and again until the accurate result is achieved. The three basic activities of data processing are: 1. Input 2. Processing 3. Output
The difference between Real data type and integer data type?
An integer data type is any type of number without a fractional part.Signed vs unsigned of any data type refers to whether or not that data type can store negative numbers (numbers with a negative sign). The typical way to store the sign information for a number is to reserve one bit of information to do so.For a signed 32-bit integer (a common integer size), this means that there are 31 bits available to hold information about the value of the number and 1 bit reserved for signifying negatives. This means that the range of data for a 32-bit signed integer is [-2147483648, 2147483647].If you use an unsigned 32-bit integer, you can use that extra bit to store more positive number values. The range of data for a 32-bit unsigned integer is [0, 4294967295].in short law FOR n bitssigned rang[-2n-1 -------- 2n-1 -1]unsigned rang [0----------2n-1]
What is the purpose of a ASCII code?
ASCII-represents letters, numbers and symbols in a 7 bit code of 1's and 0's called binary. It is a standard developed in the 1960's for information interchange between data processing equipment (teletype and computers)
What are the key features of protocol?
1. Set of rules or conventions to exchange blocks of formatted data. 2. Syntax: data format 3. Semantics: control information ( coordination, error handling ). 4. Timing: speed matching, sequencing
