Presentation on Virtual Memory concepts in computer Oshin Kandpal
Virtual Memory has reduced the memory constraints for the programmers. It creates the illusion that their whole program is running in the main memory but actually the fragments of program run at a particular instance of time.
The next big discovery after the .com boom is the internet of things. It is the technique to impart the ability to the non-living objects or our daily life gadgets to sense and understand from our surrounding environment.
Operating Systems and Memory Managementguest1415ae65
The document discusses operating systems and how they manage hardware, software, memory and processes. It defines key concepts like physical memory, virtual memory, paging, swapping and buffers. It also categorizes different types of operating systems like real-time OS, single-user OS, multi-user OS and discusses how they schedule processes and allocate system resources.
An Internet service provider (ISP) offers customers access to the Internet using various technologies like dial-up, DSL, cable modem, wireless, or dedicated high-speed. ISPs connect to upstream ISPs who have larger networks and access to more of the Internet to transmit data between networks. ISPs may directly interconnect with each other through peering points without charging for data transmission instead of going through a third upstream ISP. Types of ISPs include virtual ISPs and free ISPs. Internet access is expected to improve in cost and speed as more companies enter the industry, and the true benefit will come when remote areas worldwide can access quality Internet.
Storage provides capacity for files and information through devices like hard disks, while memory provides working space through RAM. Primary storage includes RAM and cache for running the computer, while secondary storage is long-term storage like hard disks. RAM is volatile memory used for running programs, coming in static RAM and dynamic RAM forms. ROM is read-only memory storing basic instructions. Cache memory improves performance by storing frequently used data and instructions. Optical storage includes CDs, DVDs, and Blu-rays, while magnetic storage encompasses floppy disks and hard disks. Flash memory offers portable options like USB drives and solid-state drives.

JavaScript is one of three core web programming languages, used to program the behavior of web pages. It can be used to define variables of different data types like numbers, strings, arrays, and objects. JavaScript includes various operators for assignment, arithmetic, comparison and logical operations. Key events that JavaScript can handle include onclick, onload, onmouseover, onsubmit, and onunload.
Web hosting involves purchasing domain space from an internet service provider like BSNL, Airtel, Reliance, etc. Domain names end with extensions like .com, .in, .edu, etc which indicate the type of website. Purchasing domain space provides file storage space on a server, a user ID and password to access the files, and the ability to create a website using software like Big Rock or Front Page.
This 3 sentence document summary provides essential information about the submitted work:
The document is a practical record on computer programming submitted to Mrs. Rakhi Thakur by Pratibha Kushwaha, a 6th semester electronics engineering student with roll number 12020E06037.
This document lists 5 subjects for a 2nd semester PGDCA program: System Analysis And Design, VB.net, Internet and E Commerce, Tally / C++, and a Project. Students will take courses covering system analysis and design, visual basic programming, e-commerce and the internet, accounting software or C++ programming, and work on a semester-long project.
This document appears to be describing various tools and features in a page layout or design program. It lists items like PageMaker, Tool Box, Color plate, Control palate, Scale/ruler, page, Page controller, and Past board, Area which seem to refer to different sections, menus or panels in a graphic design interface.
The document discusses operating systems and the MS-DOS operating system. It provides information on the main components of an operating system including the kernel, shell, and hardware/software management. It then describes key aspects of MS-DOS such as its command-line interface, single-tasking nature, file types (COM, MSDOS.SYS, IO.SYS), and common internal and external commands like DIR, COPY, DEL, FORMAT. The document provides details on how to use many basic MS-DOS commands and functions.
This document is a practical record submitted by Pratibha Kushwaha, a 6th semester electronics engineering student with roll number 12020E06037, to A.K. Dubey on consumer electronics.
The document discusses different generations of programming languages from binary machine code to modern high-level languages like Java and C++. It also covers key concepts in C programming like data types, operators, control structures, arrays, and pointers. Some key points covered include the differences between interpreters and compilers, common C operators and keywords, basic input/output functions, and how for, while, and do-while loops work.
