Unix is a multitasking, multiuser operating system developed in 1969 at Bell Labs. It allows multiple users to use a computer simultaneously and users can run multiple programs at once. There are several Unix variants like Solaris, AIX, and Linux. Unix was originally written for the PDP-7 computer in C programming language, making it portable. It uses a hierarchical file system and treats all resources as files with permissions. Processes run programs and the shell interprets commands to run programs or interact with the kernel for system calls. Everything in Unix is either a file or a process.

Linux command ppt
Linux command pptkalyanineve Here are the key differences between relative and absolute paths in Linux:
- Relative paths specify a location relative to the current working directory, while absolute paths specify a location from the root directory.
- Relative paths start from the current directory, denoted by a period (.). Absolute paths always start from the root directory, denoted by a forward slash (/).
- Relative paths are dependent on the current working directory and may change if the working directory changes. Absolute paths will always refer to the same location regardless of current working directory.
- Examples:
- Relative: ./file.txt (current directory)
- Absolute: /home/user/file.txt (from root directory)

Stacks IN DATA STRUCTURES
Stacks IN DATA STRUCTURESSowmya Jyothi 1) Stacks are linear data structures that follow the LIFO (last-in, first-out) principle. Elements can only be inserted or removed from one end called the top of the stack.
2) The basic stack operations are push, which adds an element to the top of the stack, and pop, which removes an element from the top.
3) Stacks have many applications including evaluating arithmetic expressions by converting them to postfix notation and implementing the backtracking technique in recursive backtracking problems like tower of Hanoi.
Functions in c mrs.sowmya jyothi

Arrays in c unit iii chapter 1 mrs.sowmya jyothi
Arrays in c unit iii chapter 1 mrs.sowmya jyothiSowmya Jyothi 1. Arrays allow storing multiple values of the same data type under a single variable name. There are one-dimensional, two-dimensional, and multidimensional arrays.
2. One-dimensional arrays use a single subscript to store elements, two-dimensional arrays use two subscripts for rows and columns, and multidimensional arrays can have three or more dimensions.
3. Arrays can be initialized at compile-time by providing initial values, or at run-time by assigning values with a for loop or other method.
Bca data structures linked list mrs.sowmya jyothi
Bca data structures linked list mrs.sowmya jyothiSowmya Jyothi 1. Linked lists are a linear data structure where each element contains a data field and a pointer to the next element. This allows flexible insertion and deletion compared to arrays.
2. Each node of a singly linked list contains a data field and a next pointer. Traversal follows the next pointers from head to tail. Doubly linked lists add a back pointer for bidirectional traversal.
3. Common operations on linked lists include traversal, search, insertion at head/specific point, and deletion by adjusting pointers. Memory for new nodes comes from a free list, and deleted nodes return there.
BCA DATA STRUCTURES LINEAR ARRAYS MRS.SOWMYA JYOTHI
BCA DATA STRUCTURES LINEAR ARRAYS MRS.SOWMYA JYOTHISowmya Jyothi 1) The document discusses linear arrays and their representation in memory. A linear array stores elements in consecutive memory locations.
2) The number of elements in an array is given by the length formula: Length = Upper Bound - Lower Bound + 1. The address of each element can be calculated using the base address of the array.
3) Common array operations like traversing, inserting, and deleting elements are discussed along with algorithms to perform each operation. Representing polynomials and sparse matrices using arrays is also covered.

BCA DATA STRUCTURES SEARCHING AND SORTING MRS.SOWMYA JYOTHISowmya Jyothi 1. The document discusses various searching and sorting algorithms. It describes linear search, which compares each element to find a match, and binary search, which eliminates half the elements after each comparison in a sorted array.
2. It also explains bubble sort, which bubbles larger values up and smaller values down through multiple passes. Radix sort sorts elements based on individual digits or characters.
3. Selection sort and merge sort are also summarized. Merge sort divides the array into single elements and then merges the sorted sublists, while selection sort finds the minimum element and swaps it into place in each pass.
BCA DATA STRUCTURES ALGORITHMS AND PRELIMINARIES MRS SOWMYA JYOTHI
BCA DATA STRUCTURES ALGORITHMS AND PRELIMINARIES MRS SOWMYA JYOTHISowmya Jyothi This document discusses algorithms and their notations. It defines an algorithm as a well-defined computational procedure that takes inputs and produces outputs. Algorithms use three main types of logic: sequential flow, conditional flow, and repetitive flow. Conditional flow uses if structures like single alternative (if/then), double alternative (if/then else), and multiple alternative (if/else if/else). Repetitive flow uses repeat structures like repeat-for (with an index from start to end) and repeat-while (with a condition). Proper comments, variable names, assignments, inputs/outputs, and procedures are also discussed for writing clear algorithms.

Buffer cache unix ppt Mrs.Sowmya Jyothi
Buffer cache unix ppt Mrs.Sowmya JyothiSowmya Jyothi The buffer cache stores recently accessed disk blocks in memory to reduce disk I/O. When a process requests data from a file, the kernel checks if the data is already cached in memory before accessing the disk. If cached, the data is returned directly from memory. If not cached, the data is read from disk into the cache. The buffer cache is managed as a pool using structures like a free list and buffer headers to track cached blocks. Caching recently used data in memory improves performance by reducing disk access frequency.
