What is the meaning of Networks, list at least two types of networks. by https://padlet.com/nattal/8Ebell Leaders of the future 8E en-us 2017-09-14 08:04:22 UTC 2024-10-14 23:36:08 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Bigthunderstorm.png Khaled Salem Alnuaimi https://padlet.com/nattal/8Ebell/wish/187461726 in technology, a computer network, also called a data network, is a series of points, or nodes, interconnected ( interrelated ) by communication paths for the purpose of sending, receiving and exchanging data, voice and video traffic.
  a network node is a connection point that can receive, create, store or send data along distributed network routes. Each network node -- whether it's an endpoint for data transmissions or a redistribution point -- has either a programmed or engineered capability to recognize, process and forward transmissions to other network nodes. 
 
local-area networks (LANs): The computers are geographically close together (that is, in the same building).
wide-area networks (WANs): The computers are farther apart and are connected by telephone lines or radio waves.
campus-area networks (CANs): The computers are within a limited geographic area, such as a campus or military base.
metropolitan-area networks MANs): A data network designed for a town or city.
home-area networks (HANs): A network contained within a user's home that connects a person's digital devices.

  • Hardware such as printers can be shared so individual workstations do not need their own printer. When they print, the data is stored in a queue on a server. The data is then passed to the printer.
  • All the users work can be stored in a central place (the dedicated file server) so a user can access their work through any computer on the network.
  • Software can be shared, software packages are stored on the server and downloaded to workstations as requested. Note that a licence still has to be bought for each copy of the software needed.
  • Data can be shared because database files stored in the server are available to users around the network; data from CD-ROMs can also be shared across the network.
  • Central back-up can take place automatically at regular intervals. A user will usually be able to retrieve work that has been deleted by mistake.
  • Messages can be sent to people working at other computers on the network which can save time and paper.
  • It is possible to set up a local intranet such as that on the KLB school network. The web pages of information can be accessed only over the LAN.  An intranet is free because it does not involve phone links.
  • There is control over users’ access rights to programs and data.

Disadvantages of LANs:

  • Printing can be slow. Where a lot of workstations are served by only one or two printers, long print queues may develop.
  • A virus can spread more easily. If a virus gets into one computer, it is likely to spread quickly across the network because it will get into the central backing store.
  • As data is shared there is a greater need for security. Users of the network have to have authentication techniques such as user ids and passwords. Unique user ID’s control access to the files and settings on the network while passwords prevent unauthorised users from logging onto the network.  Data may also have to be encrypted so that it is meaningless if intercepted.
  • If the server fails, all the workstations are affected. Work stored on shared hard disk drives will not be accessible and it will not be possible to use network printers either.
  • The cost of installing the equipment is greater. Cabling can be expensive to buy and to install.
  • Damage to cables can isolate computers. Some sections of the network can become isolated and will not be able to communicate with the rest of the network.
  • Because networks can be complicated to maintain, a network manager may be need to be employed to run the system.

    A Local Area Network (LAN) is a network that is confined to a relatively small area. It is generally limited to a geographic area such as a writing lab, school, or building

A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.
Two very common types of networks include:
You may also see references to a Metropolitan Area Networks (MAN), a Wireless LAN (WLAN), or a Wireless WAN (WWAN).
Local Area Network
A Local Area Network (LAN) is a network that is confined to a relatively small area. It is generally limited to a geographic area such as a writing lab, school, or building.
Computers connected to a network are broadly categorized as servers or workstations. Servers are generally not used by humans directly, but rather run continuously to provide "services" to the other computers (and their human users) on the network. Services provided can include printing and faxing, software hosting, file storage and sharing, messaging, data storage and retrieval, complete access control (security) for the network's resources, and many others.
Workstations are called such because they typically do have a human user which interacts with the network through them. Workstations were traditionally considered a desktop, consisting of a computer, keyboard, display, and mouse, or a laptop, with with integrated keyboard, display, and touchpad. With the advent of the tablet computer, and the touch screen devices such as iPad and iPhone, our definition of workstation is quickly evolving to include those devices, because of their ability to interact with the network and utilize network services.
Servers tend to be more powerful than workstations, although configurations are guided by needs. For example, a group of servers might be located in a secure area, away from humans, and only accessed through the network. In such cases, it would be common for the servers to operate without a dedicated display or keyboard. However, the size and speed of the server's processor(s), hard drive, and main memory might add dramatically to the cost of the system. On the other hand, a workstation might not need as much storage or working memory, but might require an expensive display to accommodate the needs of its user. Every computer on a network should be appropriately configured for its use.
On a single LAN, computers and servers may be connected by cables or wirelessly. Wireless access to a wired network is made possible by wireless access points (WAPs). These WAP devices provide a bridge between computers and networks. A typical WAP might have the theoretical capacity to connect hundreds or even thousands of wireless users to a network, although practical capacity might be far less.
Nearly always servers will be connected by cables to the network, because the cable connections remain the fastest. Workstations which are stationary (desktops) are also usually connected by a cable to the network, although the cost of wireless adapters has dropped to the point that, when installing workstations in an existing facility with inadequate wiring, it can be easier and less expensive to use wireless for a desktop.
See the Topology, Cabling, and Hardware sections of this tutorial for more information on the configuration of a LAN.
Wide Area Network
Wide Area Networks (WANs) connect networks in larger geographic areas, such as Florida, the United States, or the world. Dedicated transoceanic cabling or satellite uplinks may be used to connect this type of global network.
Using a WAN, schools in Florida can communicate with places like Tokyo in a matter of seconds, without paying enormous phone bills. Two users a half-world apart with workstations equipped with microphones and a webcams might teleconference in real time. A WAN is complicated. It uses multiplexers, bridges, and routers to connect local and metropolitan networks to global communications networks like the Internet. To users, however, a WAN will not appear to be much different than a LAN.
Advantages of Installing a School Network
User access control.
Modern networks almost always have one or more servers which allows centralized management for users and for network resources to which they have access. User credentials on a privately-owned and operated network may be as simple as a user name and password, but with ever-increasing attention to computing security issues, these servers are critical to ensuring that sensitive information is only available to authorized users.
Information storing and sharing.
Computers allow users to create and manipulate information. Information takes on a life of its own on a network. The network provides both a place to store the information and mechanisms to share that information with other network users.
Connections.
Administrators, instructors, and even students and guests can be connected using the campus network.
Services.
The school can provide services, such as registration, school directories, course schedules, access to research, and email accounts, and many others. (Remember, network services are generally provided by servers).
Internet.
The school can provide network users with access to the internet, via an internet gateway.
Computing resources.
The school can provide access to special purpose computing devices which individual users would not normally own. For example, a school network might have high-speed high quality printers strategically located around a campus for instructor or student use.
Flexible Access.
School networks allow students to access their information from connected devices throughout the school. Students can begin an assignment in their classroom, save part of it on a public access area of the network, then go to the media center after school to finish their work. Students can also work cooperatively through the network.
Workgroup Computing.
Collaborative software allows many users to work on a document or project concurrently. For example, educators located at various schools within a county could simultaneously contribute their ideas about new curriculum standards to the same document, spreadsheets, or website.

Disadvantages of Installing a School Network

Expensive to Install.
Large campus networks can carry hefty price tags. Cabling, network cards, routers, bridges, firewalls, wireless access points, and software can get expensive, and the installation would certainly require the services of technicians. But, with the ease of setup of home networks, a simple network with internet access can be setup for a small campus in an afternoon.
Requires Administrative Time.
Proper maintenance of a network requires considerable time and expertise. Many schools have installed a network, only to find that they did not budget for the necessary administrative support.
Servers Fail.
Although a network server is no more susceptible to failure than any other computer, when the files server "goes down" the entire network may come to a halt. Good network design practices say that critical network services (provided by servers) should be redundant on the network whenever possible.
Cables May Break.
The Topology chapter presents information about the various configurations of cables. Some of the configurations are designed to minimize the inconvenience of a broken cable; with other configurations, one broken cable can stop the entire network.
Security and compliance.
Network security is expensive. It is also very important. A school network would possibly be subject to more stringent security requirements than a similarly-sized corporate network, because of its likelihood of storing personal and confidential information of network users, the danger of which can be compounded if any network users are minors. A great deal of attention must be paid to network services to ensure all network content is appropriate for the network community it serves.

 

One way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network. Common types of area networks are:


  • CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network
  • PAN - Personal Area Network

LAN and WAN are the two primary and best-known categories of area networks, while the others have emerged with technology advances


Note that network types differ from network topologies (such as bus, ring and star). (See also - Introduction to Network Topologies.)

In TCP/IP networking, a LAN is often but not always implemented as a single IP subnet.


In addition to operating in a limited space, LANs are also typically owned, controlled, and managed by a single person or organization.



They also tend to use certain connectivity technologies, primarily Ethernet and Token Ring.


WAN: Wide Area Network

As the term implies, a WAN spans a large physical distance. The Internet is the largest WAN, spanning the Earth.


A WAN is a geographically-dispersed collection of LANs. A network device called a router connects LANs to a WAN.



In IP networking, the router maintains both a LAN address and a WAN address.


A WAN differs from a LAN in several important ways. Most WANs (like the Internet) are not owned by any one organization but rather exist under collective or distributed ownership and management. WANs tend to use technology like ATM, Frame Relay and X.25 for connectivity over the longer distances.


LAN, WAN and Home Networking

Residences typically employ one LAN and connect to the Internet WAN via an Internet Service Provider (ISP) using a broadband modem. The ISP provides a WAN IP address to the modem, and all of the computers on the home network use LAN (so-called private) IP addresses. All computers on the home LAN can communicate directly with each other but must go through a central network gateway, typically a broadband router, to reach the ISP.


Other Types of Area Networks

While LAN and WAN are by far the most popular network types mentioned, you may also commonly see references to these others:

  • Wireless Local Area Network - A LAN based on Wi-Fi wireless network technology
  • Metropolitan Area Network - A network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. A MAN is typically owned and operated by a single entity such as a government body or large corporation.

  • Campus Area Network - A network spanning multiple LANs but smaller than a MAN, such as on a university or local business campus.
  • Storage Area Network - Connects servers to data storage devices through a technology like Fibre Channel.
  • System Area Network (also known as Cluster Area Network) - Links high-performance computers with high-speed connections in a cluster configuration.

    What are network nodes?
    Network nodes are the network computer devices which originate / route / terminate the data. Moreover, these nodes may also include hosts namely personal computers, servers, phones or the networking hardware. Essentially, when 2 such devices are networked together one 1 of them exchanges the information even if they do not have direct connection to one another.
    Medium of computer networks
    On the other hand these computer network differ in (1) transmission medium which are used to carry their signals (2) size of the network (3) communications protocols to organize the network traffic (4) topology (5) organizational intent.

    What does the computer network support?
    There are a number of applications as well as the services which are supported by the computer network & these are digital video / access to the World Wide Web / shared use of the application & storage servers / digital audio / fax machines / printers / use of both the e – mail & the instant messaging app among other applications or services.
    Payload
    The application specific communications protocols are basically layered, it means that they are carried as payload. And this is over the other many general communications protocols.
    Types of computer network
    The types of computer networks are as follows & the computer network was divided in order to help the user.
    1. Local area network / LAN
    2. Personal area network / PAN
    3. Campus area network or campus network or cluster area network or controller area network or corporate area network / CAN
    4. Metropolitan area network / MAN
    5. Home automation
    6. Enterprise private network / EPN
    7. Storage area network / SAN
    8. Virtual private network / VPN
    9. Wide area network / WAN
    Benefits of computer network
    As we now know that the collection of computers along with the other devices which are connected together via a communication channel is known as a computer network & this is done in order to share information besides resources easily. In addition to this, these are also known as information network. Given below are the uses of a computer network –
    1. Communication – with the help of a network, people can communicate with others with the assistance of e – mail, telephone etc.
    2. Software sharing – users can access programs / software stored on the central computer
    3. Resources sharing – get access to printers, scanners, modems
    4. Data sharing – same database can be accessed at the same time; best example for this is the internet

    Two Types of Networks: LANs and WANs

    Posted on February 8, 2012 by Yejian Technologies |
    Networks are divided into two types, a LAN (Local Area Network) or a WAN (Wide Area Network), which are generic terms referring to two important basic types of networks.

    The Internet can be thought of as a bunch of LANs interconnected by WANs. An average packet will run across a company’s local Ethernet (LAN), up an ISDN or leased line or PPP link (WAN) to an Internet Service Provider. The ISP has Ethernet too (LAN) that transports the packet to the right router for delivery to a cross-country provider (WAN). The packet begins bouncing from one LAN site to another over WAN links.
