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
A
Correct answer
Explanation
In COBOL, the SORT statement is designed specifically for sequential file organization. It cannot process relative, indexed, or other file organization types directly.
-
.xml
-
.yml
-
all of the them
-
.ini
-
On your computer
-
On one massive computer - the www
-
On individual computers, often known as servers
-
On a network of routers
C
Correct answer
Explanation
Files on the Internet are stored on individual computers that are connected to the network, which are configured to serve these files and are commonly referred to as servers. The Internet is not a single massive computer, nor do files live inside routing devices.
-
Yes, Correct
-
No This is for JAR command
-
TAR and JAR are same
-
none of these
A
Correct answer
Explanation
The tar command (tape archive) is used to create and extract archive files, bundling multiple files into a single tarfile. This is its core purpose - archiving for backup or distribution. While unrelated to JAR (Java Archive), both serve similar archiving functions in their respective domains.
-
Yes, they are visible
-
No, files are not visible before mouting
-
Sometimes they are visible
-
It depends on booting option
-
It depends on file system
B
Correct answer
Explanation
In Unix/Linux, files on a filesystem are not accessible until the filesystem is mounted to a directory in the directory tree. Mounting attaches the filesystem to the directory structure, making its contents visible and accessible. Before mounting, the files exist on disk but cannot be accessed through normal file operations.
-
Read only access for Others
-
Read only access for Group
-
Read only access for Owner
-
Read only access for everyone
-
File mode
-
file size
-
File Creation time
-
File access time
-
File links count
-
all of the above
F
Correct answer
Explanation
An inode in Unix filesystems stores comprehensive file metadata including file mode (permissions and type), file size, timestamps (creation, access, modification), link count, and pointers to data blocks. All the listed components (A-E) are contained within the inode structure.
-
Owner, Group, others
-
Owner, others, group
-
Group, others, owner
-
Owner, Group, others,everyone
A
Correct answer
Explanation
Unix file permissions follow the sequence Owner-Group-Others (also called User-Group-All). This ordering is fundamental to how permission bits are organized: first 3 bits for owner, next 3 for group, last 3 for others in the octal representation.
-
cat file1 > file2
-
cat file1, file2
-
cat file1>>file2
-
cat file1 < file 2
C
Correct answer
Explanation
cat file1>>file2 uses append redirection (>>) to add file1's content to the end of file2 without overwriting existing content. Option A overwrites, option B syntax is incorrect, and option D uses input redirection incorrectly.
A
Correct answer
Explanation
QTP (QuickTest Pro) stores test scripts with the .mts extension, which represents 'Mercury Test Script.' This file format contains the test's actions, resources, and configuration data, while .usr files store user settings and .vbs contains external VBScript code.
-
odnodes configuration file
-
odbase configuration file
-
Deployment configuration file
-
deploy.cfg configuration file
C
Correct answer
Explanation
The Deployment configuration file is where entries are added to exclude files using regular expressions in OpenDeploy. This file controls deployment behavior and filtering rules. The other files (odnodes, odbase, deploy.cfg) are not the correct location for regex-based file exclusion rules.
-
CSV and ASCII files can be uploaded
-
The table used to store the flat file load parameters is RSADMINC
-
The transaction for setting parameters for flat file upload is RSCUSTV7
-
None of the above
C
Correct answer
Explanation
CSV and ASCII files are supported formats in SAP BW, so A is true. The RSADMINC table does store flat file load parameters, so B is true. C is false because the correct transaction for flat file parameters is not RSCUSTV7 (it's typically RSBATCH or file-specific maintenance transactions). Since the question asks which statements are NOT true and only C is false, C is the correct answer.
-
All Users
-
Application - Infoview Basic
-
Automatically granted
-
Folder Set
A
Correct answer
Explanation
Users get folder access to all folders through the All Users group. This group membership provides access across the folder hierarchy. Other options like Application-specific groups or Folder Sets provide more limited or targeted access, not universal folder access.
-
Filtering by File Type, File Extension, File Name
-
Filtering by File Type
-
Filtering by File Type, File Extension, File Name and File Size
-
All of the above
C
Correct answer
Explanation
Forefront Security files can be filtered by File Type, File Extension, File Name, and File Size, providing comprehensive control over file scanning and filtering based on multiple criteria.
