1 What Is Partition And It Function What Is Required Before Os Can

1. What is "Partition" and its function? What is required before OS can be installed?

A disk partition is a logically divided section of a physical storage device, such as a hard drive or SSD. Partitioning allows a single physical disk to be segmented into multiple isolated environments, which can host different operating systems, facilitate organization, and enhance data management. The primary function of a partition is to isolate data, improve system performance, and provide a structure that supports file management and OS installation. Proper partitioning ensures that the operating system and applications have dedicated spaces, reducing conflicts and improving efficiency. Before installing an operating system, the disk must be partitioned appropriately. This process involves creating primary, extended, and logical partitions using disk management tools or third-party software. The partitioning prepares the disk by formatting and setting up the filesystem, ensuring compatibility and optimal operation of the OS.

2. What is "File System" and what does it do for a computer?

A file system is a method and data structure that an operating system uses to control how data is stored, retrieved, and organized on a storage device. It defines how files and directories are named, stored, and managed on disk. Without a file system, data stored on a disk would be a large, unorganized block of data with no way to identify or access individual files efficiently. The file system manages space allocation, tracks file metadata, and maintains directory structures, ensuring data integrity and quick access. Different operating systems employ various file systems, such as NTFS for Windows, ext4 for Linux, and APFS for macOS, each optimized for specific features, security, and performance characteristics.

3. Describe the 7 file attributes in computer file system and what are the 6 operations performed on directory?

The seven common file attributes in computer file systems include:

  1. Filename: The name identifying the file.
  2. File type: Indicates the nature of the file (e.g., text, executable).
  3. Size: The size of the file in bytes.
  4. Creation date/time: When the file was created.
  5. Modification date/time: When the file was last modified.
  6. Access permissions: Permissions determining who can read, write, or execute the file.
  7. Attributes/flags: Additional attributes like hidden, system, archive, etc.

The six operations performed on directories typically include:

  1. Create: Establish a new directory.
  2. Delete: Remove an existing directory.
  3. Rename: Change the name of a directory.
  4. Open: Access the directory contents.
  5. Close: Finish operations on the directory.
  6. List: Display the contents of the directory.

These operations facilitate effective management and organization of data within the file system.

4. Review scholarly articles and reputable resources and discuss what are the latest technology/software for intrusion detection and prevention techniques. Please list your references/resources.

Recent advances in intrusion detection and prevention systems (IDPS) have been driven by the increasing sophistication of cyber threats and the proliferation of networked systems. Contemporary IDPS solutions leverage machine learning, artificial intelligence, and behavioral analytics to improve detection accuracy and reduce false positives. Signature-based detection continues to be essential, but anomaly-based detection has gained prominence due to its ability to identify unknown threats. Leading software solutions include Snort, a widely adopted open-source network intrusion detection system that offers real-time traffic analysis and packet logging (Roesch, 1999). Suricata, another open-source IDS/IPS engine, provides high-performance detection with multi-threading capabilities (OISF, 2024). Commercial solutions like Cisco Firepower and Palo Alto Networks Cortex XDR integrate advanced analytics and threat intelligence to provide comprehensive security across enterprise networks (Cisco, 2024; Palo Alto Networks, 2024). Additionally, AI-driven solutions such as Darktrace utilize unsupervised learning to detect subtle anomalies indicative of advanced persistent threats (Darktrace, 2024). The deployment of endpoint detection and response (EDR) tools, like CrowdStrike Falcon and Microsoft Defender, complements network IDS/IPS, enabling holistic security postures. Overall, the latest trends emphasize AI-powered, behavioral analytics-based systems that adapt to evolving threat landscapes, ensuring faster detection and response capabilities.
