1,249 Questions

Computer file systems dictate how data is stored, organized, and retrieved on storage devices. Important concepts include file allocation tables, access mechanisms, and various formats like sequential and video files. Candidates preparing for banking and government exams should practice these fundamentals thoroughly.

Computer File Systems Questions

Multiple choice technology
  1. Returns the number of matching data records in a Lookup File.

  2. Returns successive data records from a Lookup File.

  3. Returns a data record from a partition of a Lookup File.

  4. Returns a data record from a Lookup File which matches with the values of expression argument.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A Lookup File function returns a data record that matches the values of the expression argument passed to it. It searches the lookup file based on the expression and returns matching records. Option A is incorrect - it doesn't just return a count. Option B is incorrect - it doesn't return successive records unless they match. Option C is incorrect - it doesn't return from a specific partition without matching criteria.

Multiple choice technology
  1. Folders are structurally similar to a view.

  2. Floders also list documents, but do not have a selection criteria

  3. The user has to decide what are all the documents needs to be stored inside the folder.

  4. all of these

  5. None of these

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Folders in Lotus Notes share the structural characteristics of views but operate differently. Unlike views that use selection criteria to automatically include documents, folders are manual containers where users explicitly decide which documents to store. The user must actively place documents into folders, making folders a user-controlled organizational tool rather than a system-defined filtered list.

Multiple choice technology architecture
  1. Lists the file or directory contents that the link references

  2. Lists the name in each slot for each directory specified in the Directory parameter.

  3. Displays nonprintable characters in file names as a ? (question mark) and Reverses the order of the sort.

  4. Lists all subdirectories recursively.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

ls -lqr combines flags: -l (long format), -q (show non-printable characters as ?), and -r (reverse order). When combined, it displays detailed listings with non-printable characters replaced by ? and reverses the sort order (typically smallest files first when sorted by size).

Multiple choice technology
  1. VSAM

  2. QSAM

  3. xml file

  4. text file

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Extract records are received through QSAM (Queued Sequential Access Method), which is the standard access method for this data transfer. VSAM is a different access method, and XML/text files are not the primary mechanism.

Multiple choice technology
  1. Images are stored in FAP

  2. It contains the attributes of the object.

  3. It contains the offset value of the image

  4. FAP files can be read by the processing system and batch system.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Statement C is incorrect because FAP files store images and their attributes, not offset values. Offset values would typically be stored in separate index or reference files. Options A, B, and D describe actual FAP file characteristics.

Multiple choice technology
  1. It is a comma-delimited list of one or more recipient list.

  2. The specific recipients only receive the copy.

  3. Without defining in FORM.DAT, one can send the copy to recipient defined in recipient list.

  4. None of these

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The question asks which statement about recipient lists is incorrect. Option C states that you can send copies to recipients defined in the recipient list without defining them in FORM.DAT, which is indeed incorrect because FORM.DAT (or similar control form definitions) is required for proper recipient configuration in CICS form handling. Options A, B, and D are either correct statements or not the incorrect statement being sought.

Multiple choice technology
  1. central place for storing code to be shared

  2. to store images

  3. to store files

  4. None

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A script library serves as a centralized repository for storing reusable code that can be shared across multiple applications and design elements. This allows developers to maintain code in one place and reference it from forms, views, agents, and other components. Options B and C are incorrect because script libraries are specifically for code, not for storing images or files directly.

Multiple choice technology
  1. Image file

  2. Animation/movie file

  3. Audio file

  4. MS Office document

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The .MOV extension is Apple's QuickTime multimedia file format, specifically designed for storing video and audio content. It is a container format used for video files, not images, audio-only files, or documents.

Multiple choice technology
  1. Backup file

  2. Audio file

  3. Animation/movie file

  4. MS Encarta document

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The .BAK extension is universally used across operating systems and applications to denote backup files. When programs create backup copies of documents, configurations, or databases, they typically append .bak to indicate it's a backup copy. It's not associated with audio files, animations, or MS Encarta documents.

  1. keyboard

  2. terminal

  3. server

  4. host

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In Unix, a character special file represents a device that transmits data sequentially, byte by byte, without buffering. A keyboard is a classic example of a character input device, whereas storage devices are block devices.

  1. True

  2. False

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A Unix directory file has a minimum of 2 links: one is the directory's own entry (the '.' link), and the second is the link from its parent directory (the '..' entry in the parent pointing to this directory). This makes the statement 'minimum number of links is 2' FALSE - directory files actually have at least 2 links by default, not exactly 2, and can have more as subdirectories are added.
