A network is the interconnection of two or more computers that allows them to share resources. There are three main types of networks: local area networks (LANs), which connect computers within a building; wide area networks (WANs), which span larger geographical areas like cities or states; and metropolitan area networks (MANs), which are between the size of a LAN and WAN covering a metropolitan region. LANs have low costs but limited distance and speed, while WANs can share resources over large areas but are more expensive to set up and require firewall security. MANs interconnect users and computers within a metropolitan area, larger than a LAN but smaller than a WAN.

Computer Network Components
Computer network components include both hardware and software. The key hardware components are servers, clients, transmission media like cables, and connecting devices like switches and routers. Servers store and manage network resources, clients access these resources, and connecting devices allow communication across networks. Important software includes network operating systems and protocols that allow devices to communicate according to standard rules. Understanding the roles of these various components is essential for setting up both small home networks and larger organization networks.
Guided and unguided media
Guided media uses physical cabling to guide transmission signals along a specific path and includes twisted pair cable, coaxial cable, and optical fiber. Twisted pair cable consists of two insulated copper wires twisted together, and can be unshielded or shielded. Coaxial cable contains two conductors separated by insulation. Fiber optic cable transmits information using pulses of light through glass cores. Unguided media uses electromagnetic waves to transmit without cabling through radio waves, microwaves, or infrared signals broadcast through free space. Radio waves can travel long distances, microwaves require line-of-sight and focused antennas, while infrared works for short-range indoor use.
Types of-networks
There are several types of computer networks depending on their geographical reach: local area networks (LANs) which connect devices within a building or home; metropolitan area networks (MANs) which span a city or large campus; wide area networks (WANs) which connect LANs over long distances like countries or continents; and personal area networks (PANs) which connect devices within a few meters of an individual. LANs use twisted pair cable or WiFi to link devices for resource sharing at speeds up to 10 Gbps, while MANs and WANs transmit data over phone lines or wireless links to connect larger regions. PANs allow communication between devices in close proximity, either directly or through a larger network

LAN's And MAN's
Local area networks (LANs) are privately owned networks within a single building or campus that connect devices like personal computers and workstations. They allow for resource and information sharing between devices. LANs are distinguished by their small size of up to a few kilometers, transmission technologies used, and network topologies. Metropolitan area networks (MANs) cover larger geographical areas like an entire city and provide internet connectivity to multiple LANs. While MANs provide greater access and sharing, they are more costly and difficult to implement than LANs due to requiring more hardware, software, and security measures over a wider area.
Networking introduction
Networking involves planning, implementing, configuring, monitoring and maintaining interconnected computers that communicate and share resources. The main types of networks are LANs (covering a small area like a building), WANs (spanning large areas like countries) and hybrid networks. Networks provide benefits like sharing information, hardware and software, but also have disadvantages like security issues, virus risks and high costs. Common network topologies include bus, star and ring configurations of connected devices. Wired media include twisted pair, coaxial and fiber optic cables, while wireless uses radio waves, microwaves or infrared signals without wires.
Network
There are three main types of computer networks: local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs). LANs connect computers within a limited area like a building or campus and transmit data at high speeds. WANs connect devices over larger distances between cities and countries using technologies like telephone lines. They are more expensive than LANs but provide communication over broader areas. MANs operate at a scale between LANs and WANs, connecting multiple LANs within a city or town.

Selection of scholarly journal in Education
This document provides information on selecting scholarly journals in education. It defines scholarly journals as periodicals containing articles written by experts that present original research and findings. Scholarly articles undergo peer review to ensure quality. High quality academic journals are peer-reviewed and take longer to publish. Publishing in scholarly journals increases research visibility and helps establish expertise. Researchers should choose journals that are peer-reviewed, have a high impact factor, and are indexed in databases like Scopus. The document also discusses ethics in research like avoiding plagiarism and following guidelines on authorship and data manipulation.
Web decay and Internet Archive
This document discusses web decay, which refers to web sources disappearing over time. It provides statistics on the percentage of decayed web citations in various studies. While web sources are commonly cited in scholarly works, their URLs can become invalid if the sites change or are removed. The Wayback Machine and other archives can help recover some decayed sources. When citing web sources, authors should check URLs work and consider archiving pages themselves to mitigate decay issues.
Selection of scholarly journal
The document discusses selecting scholarly journals for research publication. It begins by providing context on India's research output and reasons for lagging behind in publications. It then defines key aspects of scholarly journals like peer review processes and impact factors. It emphasizes the importance of choosing scholarly journals to increase research visibility, establish expertise, and get more citations. The document provides tips for finding suitable journals like searching by impact factor, indexing in databases, and assessing journal structure and rigor through elements like abstracts, literature reviews, and peer review processes. Overall, the document offers guidance on selecting journals and understanding the qualities of scholarly publications.
Types of computer
This document discusses different types of computers categorized by flexibility, efficiency, and working principle. There are general purpose computers designed to solve many problems and special purpose computers designed for restricted tasks. Supercomputers are the fastest and process huge data, while mainframes support many users simultaneously processing large volumes of data ideal for organizations. Microcomputers like PCs are for individual use. Digital computers process data as numbers while analogue computers process continuous data directly. Hybrid computers have features of both analogue and digital types.
Software
This document defines and classifies different types of software. It discusses that software includes programs, applications and scripts that run on computers. It distinguishes system software, which runs computer hardware and other programs, from application software, which are general purpose programs written for specific tasks. System software is further divided into operating systems, system utilities and language processors. Operating systems manage computer operations and resources. System utilities include editors, loaders, linkers and debuggers that assist programming. Language processors translate programs into machine code.
Secondary storage devices
Secondary storage devices include floppy disks, hard disks, CDs, DVDs, Blu-ray discs, pen drives, and memory cards. These are non-volatile storage options that operate alongside primary storage like RAM. Floppy disks store data on magnetic coated plastic plates divided into tracks and sectors, while hard disks use metal plates for higher capacity. Optical discs like CDs, DVDs, and Blu-rays encode data through laser etching in pits arranged in a tight spiral, allowing greater storage densities over time. Portable options include pen drives with removable flash memory and memory cards commonly used in cameras, phones, and other electronics.
Programming
This document discusses the steps involved in programming. It explains that programming involves understanding the problem, designing a solution, writing an algorithm and flowchart, coding the program, testing and debugging it, and documenting it. It provides examples of algorithms to add two numbers and calculate the area of a triangle. It also describes some key programming concepts like what a program and algorithm are, common programming languages, and symbols used in flowcharting.
Programming languages
This document discusses several programming languages including BASIC, FORTRAN, Pascal, C, Java, and HTML. It provides brief descriptions of each language, noting that BASIC was developed as a teaching aid, FORTRAN was used for scientific applications, Pascal supports structured programming, C was developed at Bell Labs, Java is a general purpose object-oriented language, and HTML is the standard markup language for web pages. The document also lists some common HTML tags like title, paragraph, and lists and describes their basic functions.
Output devices
This document discusses various computer output devices. It describes monitors, speakers, printers, plotters, and multi media projectors. Monitors display visual information using LCD screens. Speakers generate sound signals from a computer's sound card. Printers take electronic data and output a physical copy using various technologies like inkjet, laser, or dot matrix printing. Plotters produce vector graphics drawings by drawing lines with a pen. Multi media projectors display images or moving images onto a surface using light through a lens or directly with lasers.
Online learning courses
This document discusses online learning courses and MOOCs. It summarizes that online learning uses electronic technologies to access educational curriculum outside of a traditional classroom, providing affordable and flexible learning. MOOCs are massive open online courses that are free and have unlimited enrollment. SWAYAM is an Indian government program that enables professors from top institutions to offer online courses to Indian citizens, with the goal of improving access, equity, and quality of education. Courses on SWAYAM have video lectures, readings, self-assessments, and discussion forums.
Library networks
This document discusses several library networks in India, including INFLIBNET, DELNET, and CALIBNET. INFLIBNET was established in 1991 as a national program initiated by the University Grants Commission of India to link libraries and information centers. Its objectives include avoiding duplication of efforts and creating databases. DELNET was started in 1988 to promote resource sharing and reduce unnecessary duplication among libraries. It maintains various union catalogues and databases. CALIBNET, funded in 1993, provides online access to library resources in West Bengal grouped under bibliographic, factual, and intellectual asset categories.
Language processors
This document discusses different types of programming languages and language processors. It describes low-level languages like machine language and assembly language that are directly understood by computers. It also describes high-level languages that are easier for humans to read and write but require compilers or interpreters to be converted to machine code. Language processors like assemblers, compilers, and interpreters are used to convert programs between source and machine codes.
Internal storage devices
Primary storage devices include cache memory and RAM that are located inside the computer. Cache memory temporarily stores frequently used data closer to the CPU than RAM for faster access. RAM holds programs and data being actively processed. ROM is non-volatile memory that stores critical instructions and cannot be changed by the user, including BIOS programs. Different types of ROM are MROM, PROM, EPROM, and EEPROM, which can be electrically erased and reprogrammed unlike MROM and PROM.
Input devices
Input devices allow users to input data and instructions into a computer system. The keyboard and mouse are commonly used input devices that allow typing and pointing respectively. Other input devices include microphones, touchpads, light pens, digital cameras, optical mark readers, barcode readers, scanners, and touch screens, each of which facilitates a different type of input such as audio, hand gestures, drawings, photographs, test responses, product codes, documents, and touch interactions.
Information and communication technology
This document discusses the history and evolution of information and communication technology (ICT). It describes how ICT has evolved from early manual methods of recording and storing data using clay tablets, stones, and paper, to modern digital methods using microfilm, magnetic tapes, hard disks, flash memories, and optical discs. It also discusses how tools for analyzing data have advanced from the abacus to analytical engines, calculators, and computers. Finally, it outlines different technologies used for communicating data, from early telegrams and telephones to modern fax, mobile, and internet technologies.
Generations of computer
The document discusses the five generations of computers from the 1940s to present. The first generation used vacuum tubes and magnetic drums, were large in size, and operated slowly. The second generation introduced transistors, were smaller with less heat, and operated at microsecond speeds. The third generation used integrated circuits, were smaller still with assembly level programming and nanosecond processors. The fourth generation used microprocessors, high-level languages, and operated at picosecond speeds. The fifth generation aims to develop artificial intelligence with natural language and self-learning capabilities.
Evaluation of search engine
The document discusses criteria for evaluating search engines, including recall, precision, novelty/up-to-datedness, search time, database, relevancy, indexing, user interface, query functionality, and help/advanced search options. Recall is defined as the fraction of relevant search results retrieved from the database, and precision is the fraction of retrieved results that are relevant. High recall and precision are important for search engines. Other factors like indexing speed, up-to-datedness of the database, relevancy algorithms, user experience, and support functions also impact search engine quality.

HijackLoader Evolution: Interactive Process Hollowing
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.
