Types of Storages

Primary memory

Components:
Registers: Very small, very fast storage locations within the CPU itself. They hold data that the CPU is currently processing. Registers are the fastest type of memory.
Cache Memory: A smaller, faster type of volatile memory that provides high-speed data access to the CPU. It stores frequently used data and instructions to speed up processing.
RAM (Random Access Memory)/ Main memory: Temporarily stores data and instructions that the CPU needs while performing tasks. It is fast and volatile, meaning it loses its data when the power is turned off.
Characteristics:
Speed: Extremely fast, especially registers and cache memory, allowing quick read and write access.
Volatility: Volatile, meaning data is lost when the power is turned off.
Capacity: Typically smaller in capacity compared to secondary memory.
Purpose: Used for immediate data access by the CPU, running active applications, and executing instructions.

Secondary memory
Components: 
Hard Disk Drives (HDD): Mechanical drives that use spinning disks to read/write data. They offer large storage capacities at a lower cost. 
Solid State Drives (SSD): Faster, non-mechanical drives that use flash memory to store data. They are more expensive per unit of storage but provide better performance. 
Optical Discs: CDs, DVDs, and Blu-rays used for storing data, music, videos, and software. 
USB Flash Drives: Portable storage devices using flash memory, ideal for transferring files between computers.
Characteristics:
Speed: Slower compared to primary memory, but still adequate for storing and retrieving data.
Volatility: Non-volatile, meaning data is retained even when the power is turned off.
Capacity: Much larger capacity than primary memory, capable of storing large amounts of data.

Indexed allocation

Image
  Indexed allocation is a file allocation method used by operating systems to manage how files are stored on disk. The core idea is simple but powerful: instead of storing a file in contiguous blocks or linking blocks one-by-one, the system uses a special index block that contains a list of all the disk block addresses where the file’s data is stored. This removes many limitations of earlier methods like contiguous and linked allocation. In indexed allocation, each file has its own index block . This index block acts like a table of contents. Every entry inside it points to a data block that belongs to that file. When a file is created, the OS allocates an index block and then fills it with pointers to the actual data blocks as the file grows. These data blocks can be located anywhere on the disk , so the file does not need contiguous space. This makes storage much more flexible and avoids external fragmentation. When the system needs to access a particular part of a file, it fir...

Thrashing

Image
Thrashing occurs in a computer system when the operating system spends a significant amount of time swapping pages in and out of memory, rather than executing actual processes. This typically happens when the system's memory is overcommitted, meaning there are too many processes competing for too little physical memory, leading to frequent page faults. How Memory is Used 1. Initial State: App1 is running, and its two pages are loaded into memory: Frame 1: App1, Page 1 Frame 2: App1, Page 2 Frame 3 and 4 are free. App3's pages are present in swap memory. 2. Switch to App2: Now, you switch to App2, which also requires 2 pages: Frame 3: App2, Page 1 Frame 4: App2, Page 2 Memory is now full with both App1 and App2’s pages. App3's pages are present in swap memory. 3. Switch to App3: You decide to switch to App3, which needs 2 pages as well. Since the memory is full, the system needs to make room: App1’s pages are moved to swap memory: Swap Memory: [App1, Page 1] [App1, Page 2] F...

Basics of paging

Image
Paging is a memory management scheme that eliminates the need for contiguous allocation of physical memory and thus helps in handling fragmentation. It involves breaking down memory into fixed-size blocks called pages and frames. The OS typically decides the page size when the system is configured or during the OS design phase. This page size is constant for the entire system and is determined based on considerations such as hardware architecture, efficiency, and the type of applications running. Common page sizes are 4 KB, 8 KB, or 16 KB. Here's a simple explanation with an example: Basic Concepts Page: A fixed-size block of logical memory (virtual memory) used by a process. Frame: A fixed-size block of physical memory (RAM) where a page is mapped. Page Table: A data structure used by the operating system to keep track of the mapping between pages and frames. The Page Table Base Register (PTBR) is a special register in the CPU that holds the starting address of the page table for ...
