Which of the following places the common data elements in order from smallest to largest? 1. Character, File, Record, Field, Database 2. Character, Record, Field, Database, File 3. Character, Field, Record, File, Database 4. Bit, Byte, Character, File, Record, Field, Database Select the correct answer using the codes given below. Correct Answer Only 3

The correct answer is Only 3.

Key Points

  • The common data elements in order from the smallest to largest are Character, Field, Record, File, and Database.
  • A database is a collection of files, a file is made up of records, a record is made up of fields, a field is made up of characters, a character is made up of bytes and a byte is made up of bits (a bit is a short form for binary digit).

Additional Information

  • Bit (Character) is the smallest unit of data representation (value of a bit maybe a 0 or 1).
    • Eight bits make a byte which can represent a character or a special symbol in a character code.
  • The field consists of a grouping of characters. A data field represents an attribute (a characteristic or quality) of some entity (object, person, place, or event).
  • The record represents a collection of attributes that describe a real-world entity. A record consists of fields, with each field describing an attribute of the entity.
  • A file is a group of related records. Files are frequently classified by the application for which they are primarily used (employee file). A primary key in a file is the field (or fields) whose value identifies a record among others in a data file.
  • The database is an integrated collection of logically related records or files. A database consolidates records previously stored in separate files into a common pool of data records that provides data for many applications.

Suppose you are compiling on a machine with 1-byte chars, 2-byte shorts, 4-byte ints, and 8-byte doubles, and with alignment rules that require the address of every primitive data element to be an integer multiple of the element's size. Suppose further that the compiler is not permitted to reorder fields: padding is used to ensure alignment. How much space will be consumed by the following array? struct { short s; char c; short t; char d; double r; int i; } A[10]; /*10-element array of structs*/
Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of y are initialized to 0 and each element X[i] [j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of x are in same main memory page frame. Code segment 1:                 //initialize elements of y to 0                 //initialize elements X[i] [j] of X to i+j                       for (i = 0; i < n; i++)                                 Y[i] += X[0] [i]; Code Segment 2:                 //initialize elements of Y to 0                 //initialize elements X[i] [j] of X to i+j                        for (i = 0; i < n; i++)                                 Y[i] += X[i] [0]; Which of the following statements is/are correct? S1: Final contents of array Y will be same in both code segments S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory
The given question consists of three statements numbered I, II and III. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the statements and answer the question. What will be the sum of two numbers? I. Among the two numbers, the largest number is greater than the smallest number by 4. II. 30% of the smallest number is equal to 20% of the largest number. III. The ratio between half of the largest number and one fourth of the smallest number is 3 ∶ 2.
Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.

In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the suggested course of action logically follow (s) for pursuing. Statement: The India Risk Survey 2017 report ranks 'Information & Cyber Insecurity' as the biggest risk facing Indian companies. Indian organizations, both public and private, had witnessed over 27,000 incidents of security threat, from January 2017 till June 2017 alone. Phishing, scanning/probing, website intrusions and defacements, virus/malicious code, ransomware, Denial of Service attacks, and data breaches are some ways in which hackers attack business websites, which can cause operational disruptions and potentially steal sensitive information. Small and medium businesses (SMBs), unfortunately, have been seeing rising incidences of cybercrime. In fact, 70 percent of cyberattacks occur at organizations with lesser than 100 employees  Courses of action: I. Mandate basic security practices and policies for all employees, such as 2-factor authentication, internet use guidelines and create and enforce rules on handling and protecting sensitive data. Conduct frequent training to sensitize employees about opening suspicious emails, encrypting their data, using strong passwords on their devices, installing security apps, and limiting activity over public Wi-Fi. Implement and enforce incident reporting to help ensure that even the smallest breach is report to management as well as the IT teams. II. Basics still matter and are some of the best defenses against viruses, malware, and other online threats. Assess the assets that are most at risk - data, servers, network - and ensure that the systems are updated with the latest security software, web browser, and operating system. Implement firewall security and run antivirus software after each update.  III. Ensure regular backup of all critical data - whether stored in-house or on the cloud. Run scheduled attack drills and stress tests to identify vulnerabilities and ensure that data restoration and business continuity are executed as planned.
