Networking and its importance in the IT industry
Information and communication are two of the most important strategic issues for the success of every enterprise. While today nearly every organization uses a substantial number of computers and communication tools ( telephones, fax, personal handheld devices), they are often still isolated. While managers today are able to use the newest applications, many departments still do not communicate and much needed information cannot be readily accessed. To overcome these obstacles in an effective usage of information technology, computer networks are necessary.
ITFT_Wireless network
Wireless networks use electromagnetic waves instead of wires to transmit data between devices. They provide flexibility and mobility as no physical connections are needed. Common examples of wireless technologies include cellular networks, WiFi, and GPS. Wireless networking has evolved from early experiments in the late 19th century using radio waves, to the development of the IEEE 802.11 wireless network standard in 1990 and the widespread adoption of wireless Internet access through technologies like WiFi routers. Key components of a wireless network include an Internet connection, wireless devices, a wireless router, and wireless adapters in each device.
Computer networks
The document discusses computer networking and key concepts related to networking including:
- Computer networks allow computing devices to communicate and share resources by connecting via physical wires, cables, or wireless connections.
- Networks operate using a client/server model where clients make requests and servers respond to fulfill those requests.
- Common server types include file servers and web servers.
- Networks can be local-area networks or wide-area networks connected across distances.
- Standards like the OSI reference model and protocols like TCP/IP help networking function across different systems.
Vision
This document provides an overview of a computer network called VISION. It discusses the network's goals of being secure, intact, and organized. It then describes different network types (LAN, MAN, WAN), common network devices (hubs, switches, routers), IP addressing, and major modules covering network design, security, and recovery. Key features include preventing IP waste, providing cost-effective solutions, implementing wireless networks, and incorporating security measures like ACLs, VLANs, and NAT. The network aims to be highly secure while also offering recovery mechanisms in a cost-effective manner.
TYPICAL ELEMENTS IN A LAN
A local area network (LAN) connects computers within a building or nearby buildings to allow users to share devices, programs, files and emails. Each computer connects to the LAN through a network card installed in the computer with an RJ45 port. Switches are networking devices that have multiple RJ45 ports and are faster than hubs, knowing which computers are connected to each port. Routers connect multiple networks, with home networks typically using a wireless router. The TCP/IP protocol ensures reliable transfer of information between different operating systems and networks by using TCP to reliably transfer data and IP to deliver it to the destination computer identified by its unique IP address.
wireless net workes
An ad hoc network connects two or more devices directly without a wireless access point for quick data exchanges or multiplayer gaming. Cordless mice transmit data via infrared radiation or radio signals to a receiver connected to the computer via USB or built-in. Wireless keyboards use either infrared light waves or radio frequencies from 27MHz to 2.4GHz to communicate with devices, with most modern keyboards using 2.4GHz radio signals.
Class no. 3 Computer Network
A computer network connects computers and devices through communication channels, allowing users to share resources and communicate more easily. It uses both wired and wireless technologies. The basic hardware components of a computer network include network interface cards, bridges, hubs, switches, and workstations, which are used to interconnect nodes on the network and facilitate communication between connected devices.

Bluetooth
This document summarizes a seminar on Bluetooth technology. Bluetooth allows for short-range wireless communication between various smart devices. It uses frequency hopping across 79 channels from 2.4-2.4835 GHz to mitigate interference. Bluetooth enables automatic synchronization and connection to the internet between mobile and stationary devices without cables. Security is provided through encryption and coordinated encryption keys. While Bluetooth provides low-power and low-cost connectivity, wireless LANs offer faster speeds and larger ranges.
Wireless local area netwok slide
A wireless local area network (WLAN) allows devices to connect to a local network using radio waves instead of cables. WLANs provide connectivity for devices like laptops, phones, and smart appliances over distances of hundreds of feet. Key advantages of WLANs are mobility and easier installation compared to wired networks. However, WLANs also face security risks and reliability issues from signal interference that wired networks do not.
Communication line, communication devices and home network
A home network connects devices in a home to share internet access and files. It uses communication lines like cables or WiFi. A router establishes the wireless network that devices connect to wirelessly or via cables. Setting up a home network involves connecting the router to the internet, configuring the router's wireless network name and password, and connecting devices to it either wirelessly or with cables. This allows sharing of an internet connection and files between devices in the home.
Networking
A network is any collection of computers connected together to share resources. When computers are connected in a network, users can share files, printers and other devices. As companies rely more on applications like email and databases, computer networking becomes increasingly important. Networks include computers, networking cards, connections like wires, and network operating systems. There are different types of networks like LANs, WANs, intranets and the Internet. Devices like repeaters, hubs, bridges, gateways and switches are used to connect network segments and devices.
Telecommunications and Networks.
Telecommunications involves the digital transmission of data and voice communications using computers, terminals, communication processors, and software. Signals can be analog, representing continuous waveforms, or digital using discrete 1s and 0s. Modems translate between digital and analog signals. Network topologies include star, bus, and ring configurations. Communications networks span large distances using various cable, satellite, and microwave technologies to connect local area networks (LANs) and wide area networks (WANs). Electronic business technologies enable e-commerce through email, groupware, voice mail, fax, teleconferencing, video conferencing, and distance/e-learning. Electronic data interchange directly exchanges standard business documents between organizations' computers.
IoT Heaps 5

Networks
This document discusses computer networks and their key components. It defines a computer network as a collection of computers that communicate with one another over transmission lines. The main types are local area networks (LANs), wide area networks (WANs), and the Internet. LANs connect computers within a small physical area like a home or office, while WANs connect computers across multiple locations using communication networks from vendors. Other topics covered include network interface cards, Internet service providers, WiMax technology, firewalls for security, and virtual private networks which use encryption to securely connect remote locations.
Infra red
Infrared and radio transmission are two technologies that can be used to set up wireless local area networks. Infrared transmission uses infrared diodes and diffuse light bouncing off walls and furniture, while radio transmission typically uses the 2.4 GHz license-free band. Both technologies can be used to connect devices like desktops and printers without wires and enable mobility within a small area.
Explaining network hardware
This document discusses various network hardware components used to connect devices in a network. It describes repeaters, hubs, bridges, switches, and routers. Repeaters amplify weak signals and retransmit them. Hubs provide a common connection but can become overloaded. Bridges divide large networks into smaller segments. Switches dynamically connect any two nodes to improve efficiency. Routers route data between networks and keep routing tables to determine the best transmission path.
5 Lan
A LAN is a high-speed network covering a small geographic area that connects devices like computers and printers. It allows shared access to devices, file sharing, and communication via email. LANs use protocols like Ethernet and Token Ring and media access methods like CSMA/CD and token passing to allow devices to communicate on the shared network medium. Common LAN devices include hubs, switches, bridges, and routers that operate at the data link layer and network layer to connect, segment, and route traffic between LAN segments.
Types of Network
There are several types of computer networks including LAN, MAN, PAN, CAN, and WAN. LAN connects devices within a short area like an office or home. MAN connects multiple LANs within a large city. WAN is the largest type of network, connecting LANs across great distances like the Internet. PAN connects personal devices close to an individual. CAN networks multiple LANs within a campus setting like a university.
Basic network
A computer network connects computers and devices together to allow for sharing of information. Computers can connect either through wired or wireless connections. A network application allows programs running on different computers to communicate with each other using protocols like HTTP for web browsers and servers or SMTP for email. This facilitates information sharing and communication between interconnected devices on the network.
Computer networks basic network_hardware_1
The document discusses basic networking concepts including LANs, wireless LANs, network hardware, common network media, and Ethernet specifications. It defines a LAN as a group of computers and devices sharing resources within a small geographic area. Wireless LANs transmit over the air using unlicensed frequencies. Common network hardware includes hubs, switches, bridges, routers and network interface cards. Wired networks typically use copper or fiber optic cable, while wireless networks transmit over radio frequencies. The document provides examples of LAN implementations in home and business configurations.
EclipseCon NA 2016: The Things Network
There are four constraints for internet of things to succeed: devices should have connectivity even on a long range, connectivity should be free and secure, devices consume very little power and the form factor is reduced to the size of the battery. LoRa enables this: long range, low power communication over free-to-use frequencies around the world. In this talk, I will introduce the open standard LoRaWAN: the wide area network protocol stack built on top of LoRa, maintained by telecom operators, chipmakers and IoT industry leaders.
With a $ 1,200 gateway in our hands, we imagined covering the city of Amsterdam with only ten gateways. Four weeks later, we crowd sourced the gateways and launched the first open LoRa covered city network in the world. The open source, open hardware initiative, The Things Network, spread like wildfire around the world. After a very successful Kickstarter campaign to enable producing affordable gateways, development kits and nodes, we started building the network with the community. LoRaWAN is at the core of this network, and in this talk I'll explain its role in our mission to build an open, decentralized and crowd sourced internet of things data network with global coverage.

ГОВАРД ФИЛЛИПС ХАРТ/ ЖИЗНЬ ЗА ЖИЗНЬ - ВОСПОМИНАНИЯ ОФИЦЕРА ЦРУ
Эта книга – рассказ оперативного офицера, служившего в американской разведке. Она начинается с истории о том, как он с родителями был интернирован японцами в лагере на Филиппинах во время Второй мировой войны, и как его освобождение из лагеря американскими десантниками привело его к мысли служить своей стране в разгар Холодной войны. Говард Филлипс Харт большую часть своей двадцатипятилетней карьеры прослужил в Южной Азии и на Ближнем Востоке. Он своими глазами видел Исламскую революцию в Иране; он планировал, начинал и проводил широкомасштабные программы секретной операции ЦРУ против советского вторжения и оккупации Афганистана; и он как представитель ЦРУ участвовал в планировании неудачной попытки спасти заложников из американского посольства в Иране в 1980 году. Говард Харт был основателем и директором Центра ЦРУ по борьбе с наркотиками.

IP ADDRESSING.pptx
The document summarizes the history and development of computer networking. It describes how ARPANET, developed in the 1960s, connected several universities and allowed for the first transmission of data between networked computers. This led to the creation of the internet as more networks were interconnected. Key developments included the introduction of TCP/IP in the 1980s and the creation of the World Wide Web in the 1990s. The document also provides an overview of networking concepts such as local area networks (LANs), wide area networks (WANs), and IP addressing.
Computer Networks .pdf
Computer networks allow interconnected computers and devices to communicate and share resources. The key types of networks include local area networks (LANs) within an office or building, metropolitan area networks (MANs) spanning a city, and wide area networks (WANs) covering large geographical areas like countries. Early networks included ARPANET developed by the US Department of Defense and NSFNET created by the National Science Foundation. Today's internet evolved from these early networks combining ARPANET, NSFNET and private networks.
Lan and wan technology
Local area networks (LANs) connect devices over small areas like offices and buildings. Common LAN types include star, bus, ring, and tree topologies. Essential LAN components are network interface cards, hubs, switches, routers, and gateways. While many LAN technologies existed, Ethernet is now dominant using protocols to enable communication between devices over cables. Token ring was another standard using a ring topology and token passing for transmission. Wide area networks (WANs) span larger geographical areas, connecting multiple LANs. WANs use routers, switches, and modems along with technologies like point-to-point, circuit switching, and packet switching to relay data over long distances.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
- **Efficient Use of Bandwidth**: TDM all

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
