Question

• Outline the objectives and functions of file systems management and the supported operations, including their reliability and performance.
• Contrast different directory structures and create unique diagrams to illustrate an example of each directory structure (similar to Figures 10.9, 10.10, 10.11, 10.12, and 10.13 in your textbook). Insert these images as nodes of your concept map. To create your diagrams, you can choose to use a graphics editing software (PowerPoint, Paint, PhotoShop, etc.), an online mapping software tool (draw.io (Links to an external site.)), or even upload a photo of a hand-drawn sketch.
• Describe different types of input/output devices, distinguishing between the hardware and software layers and summarizing the integration across I/O and memory components.

Logically arrange the essential concepts about files, mass storage, and I/O into a hierarchy of nodes that branch from the main idea. Include cross-links where necessary to show relationships in different sections of the concept map. Use connecting nodes to accurately describe each relationship between topics that connect. Section 4 must have at least three nodes and at least four connecting nodes.

Answer 1

Answer:

• A significant aspect of the OS is the file management framework. Its primary purpose is to handle a file on a machine. The file management system has to create, update, and remove records. It also helps to locate archives and to change the details in those archives.
• It handles folders known as directories, which help arrange files since they are grouped by category and usage. It is likely because, depending on the operating system, file structures will be different.
• The attributes may be different, but some of the items between operating systems are typically the following: name, identity, form, position, height, security, time and date, and identity of the user.
• The file system includes a particular naming convention that defines whatever characters in the name should be used. There are file systems to help coordinate items.
• There is a registry, and there are directories and files in a hierarchical order that are ordered. A single-level directory easily supports all files in the same directory, although there are drawbacks if two users need to be special in and folder file names.
• It doesn't happen to group the same sort of file together. The next step of folders is level 2. Here, because each user should have his directory, there are two folders.
• This allows it easy to scan for data, and users will use the same directory, and it is sorted by user username, but this is not a collection of scalable data of the same kind. The form of the tree is deemed the most prominent and has a height of 2 and can increase its form.
• Users and sub-directories are generated in this specific directory. It's modular and has a name for the entire route. Since each file might not be a hierarchical file, end up in many folders. This allows it impossible to reach certain data as this sort of directory will share files in different folders. The Acyclic directory. It is simple to transfer files here, but sharing if files are lost will lead to problems.
• Cycles are allowed by the general graph structure, and several folders may come from one parent directory. It provides greater consistency than most systems, but the scale of data is one of the greatest challenges with this form of framework.
• Input data in computers and output systems supply the result with I / O devices or input-output devices. The screen, cursor, touchpad, TrackPoint, printer, microphone, portable cameras, barcode reader, joystick, webcam, etc. are several input devices. Printers, projectors, plotters, displays, microphones, headphones are items that are called output devices.

• Between internal storage and an I / O port, information is transmitted. Special correspondence exists to support the variations between the device and peripherals to be understood. To synchronize the input and output, there are connectivity connections and hardware that both operate together.
• This information is passed to an external computer to transmit information that is contained in a memory unit. The CPU can interpret knowledge. In many different ways, data transmission between the CPU and I / O devices may occur.
• Programmed I / O, I / O triggered by interrupt and DMA for direct memory entry. In this case, configured I / O, interrupt- initiated I / O requires intervention between the processor and memory; any data would need to travel through the processor because the processor's speed influences the transmission rate.
• This allows the processor with each I / O switch to tackle commands that need to be followed. Allowing peripherals to interact explicitly with each other eliminates the CPU's interference.
• The CPU sits idle, and the memory bus has little power over it. The I / O modules and the memory unit are explicitly moved, respectively.
