Network terminology

The major Network terminology used in computer networking –

WAN

It stands for Wide Area Network and covers a wide area such as a city.

LAN

It stands for Local Area Network and covers a small area such as a small office or home. It physically connects all the computers located in the premises.

Internet

It is a computer network system that connects the computers of the world. It is normally connecting through WAN and LAN.

Intranet

It is a close room computer network system, as it covers a small area and only authorized people can access it.

Extranet

It is also a sort of Internet the access to which is granted only to a few.

World Wide Web (WWW)

It is the service that is used on Internet to view and search contents (in the form of web-pages).

Instant messaging (IM)

It is an online facility that facilitates us to chat or talk. Such service is provided by Skype, Google Talk, Windows Live Messenger, Yahoo Messenger, etc.

Voice over Internet Protocol (VoIP)

It is a Protocol, which is used especially for voice transfer over IP network. Likewise, it facilitates users to make phone-calls by using internet.

Really Simple Syndication (RSS)

Definition of networking

 Definition of Networking is given as a network is two or more computers (or other electronic devices) that are connected together, usually by cables or Wi-Fi.

Some computer networks will have a server. A server is a powerful computer that often acts as a central hub for services in a network, eg emails, internet access and file storage. Each computer connected to a server is called a Client.

A computer that is not connected to a network is called a standalone computer.

Using a network allows you to share:

·         hardware, such as a printer

·         software, allowing multiple users to run the same programs on different computers

·         data, so that other people can access shared work and you can access your data from any computer on the network

Networking is critical if you want to use your computer to communicate. Without it you couldn’t send an email, a text or an instant message.

We use a huge network on a daily basis and this is called the internet. Around three billion people use the internet to share data, news and resources, amongst many other things.

definition computer networks

Definition computer networks: computer network is defined as the interconnection of two or more computers. It is done to enable the computers to communicate and share available resources.

APPLICATIONS:

 I Sharing of resources such as printers

ii. Sharing of expensive software's and database

 iii. Communication from one computer to another computer

 iv. Exchange of data and information among users via network v. Sharing of information over geographically wide areas.

THE USE OF COMPUTER NETWORK

 ¨ Business Applications ¤ online buying

¨ Home Applications ¤ mail, chat

¨ Mobile Users ¤ wireless: laptops, PDA, mobile, in plane

¨ Social Issues

•Sharing information — i.e. data communication

•Sharing hardware or software

¨ Centralize administration and support

COMPONENTS OF COMPUTER NETWORK Ø

 Two or more computers

Cables as links between the computers

A network interfacing card(NIC) on each computer

Switches

Software called operating system(OS)

wide area network definition

Wide area network definition WANs are large communication networks that connect locations over a wide geographical area, including cities, states, countries, and continents. Enterprise WANs are often built for one organization and are usually private. Often, they’re created using leased lines involving a direct point-to-point connection between two private sites. A leased line is a direct connection between two points set up by a telecommunications carrier, like a T-1 channel. And while they resemble Local Area Networks (LANS) a great deal, WANs are structured and operate quite differently.

WANS aren’t new, they’ve been around for a while with some people tracing their roots to the 1970s, 1980s and even the 1990s. That’s when Frame Relay Service appeared as an alternative to the point-to-point service options then being offered. This new service offered numerous advantages including lower monthly costs, fewer physical connections to oversee, and less expensive router hardware to manage. In any case, WANs represented a viable communication option for businesses and remain so today.

How to network computer

How to network computer? Computers are general-purpose machines that mean different things to different people. Some of us just want to do basic tasks like word processing or chatting to friends on Facebook and we couldn't care less how that happens under the covers—or even that we're using a computer to do it (if we're using a smartphone, we probably don't even think what we're doing is "computing"—or that installing a new app is effectively computer programming). 

At the opposite end of the spectrum, some of us like modifying our computers to run faster, fitting quicker processors or more memory, or whatever it might be; for geeks, poking around inside computers is an end in itself. Somewhere in between these extremes, there are moderately tech-savvy people who use computers to do everyday jobs with a reasonabe understanding of how their machines work. Because computers mean different things to different people, it can help us to understand them by thinking of a stack of layers: hardware at the bottom, the operating system somewhere on top of that, then applications running at the highest level. You can "engage" with a computer at any of these levels without necessarily thinking about any of the other layers.

 Nevertheless, each layer is made possible by things happening at lower levels, whether you're aware of that or not. Things that happen at the higher levels could be carried out in many different ways at the lower levels; for example, you can use a web browser like Firefox (an application) on many different operating systems, and you can run various operating systems on a particular laptop, even though the hardware doesn't change at all.

what is network technology

What is network technology? Network technology is any technology by which two or more computer systems are connected and communicate information between them. ... From a more human standpoint, though, network technology is any technology by which people communicate with one another, and reach out to each other.

The technology network is an account of all transformation, transport, distribution, and storage technologies of a specific energy system. In that network, technologies are represented as directed links. The layout of the network is depicted in Fig. 4. Fundamental to this representation is that, both at the resource and the demand levels, energy is grouped by functional classes. For resources, it distinguishes between mechanical, chemical, and thermal origins. Demand categories are:

special processes (e.g. lighting and electrolysis);

mechanical processes (e.g. engines)

low-temperature heat (e.g. residential space and water heating);

high-temperature heat (e.g. thermochemical processes and process heat (‘steam’)).

At the demand level, the system further distinguishes by type of sector, viz. industrial, transportation, commercial, and residential use, respectively.

servers computer definition

Let’s try to know the servers computer definition.A server is a computer that provides data to other computers. It may serve data to systems on a local area network (LAN) or a wide area network (WAN) over the Internet. Many types of servers exist, including web servers, mail servers, and file servers. Each type runs software specific to the purpose of the server.

A server is a type of computer or device or network that manages network resources Servers are often dedicated meaning that they perform no other tasks besides their server tasks. On multiprocessing operating systems, however, a single computer.

One of the best choices for a small business is a dedicated server built from the ground up as a file server to provide features and expansion options that a desktop computer lacks. Before investing in server hardware, you need to consider many things including the server operating system, applications, storage, processor, form factor, memory and more to help you choose wisely.

Web servers are computers that deliver (or serve up) Web pages. Every Web server has an IP address and possibly a domain name. There are many Web server software applications, including public domain software and commercial packages.

what is a lan

What is a LAN? A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link and typically share the resources of a single processor or server within a small geographic area.

A local area network (LAN) is a computer network in a small area like a home, office, or school. Many computers can be connected to share information and Internet connections. Most LANs use Ethernet to connect together. LAN topologies tell you how ROM devices are organised.

You may consider using a LAN to connect to the internet. LANs come in two basic varieties: wired and wireless. In a wired network, a cable runs from each computer to a central box, whereas a wireless network uses radio signals rather than wires.

wifi management

A Wifi Management is a tool used for managing your home network. You may also see this tool called 'managed Wi-Fi' or a 'network monitoring software. A  WiFi manager provides customized insight into various aspects of a network, like network security or the ability to manage connected devices including parental controls.

Managed WiFi provides WiFi internet access for guests, residents and employees throughout a property. The design typically include devices such as wireless controllers, wireless access points, switches and extensive cabling.

The implementation process involves all activities needed to make the network operational. The core activities are cabling, access point installation, and integration of Internet service and WiFi network.

The wireless router has a WI-FI access mode without authentication. Thus the user can freely connect to the router WI-FI network but this does not provide internet connection. In fact, as soon as the user opens the browser, s/he will be automatically redirected to a login page (captive portal) to login to the system, entering his/her credentials

wifi as a service

WiFi as a Service is a subscription-based service that combines three key elements: infrastructure, software, and managed services.

With WiFi as a Service, we have taken our proprietary methodology—developed over the last eleven years designing and installing large-scale wireless networks (on average 450 access points per deployment)—and packaged virtually every aspect of a high-performing, secure WiFi network into one end-to-end solution.

Our  WiFi as a Service are flexible. There are two primary routes you can take: You can either a) purchase the hardware or equipment with a large one-time payment and then purchase managed services using a monthly subscription, or b) purchase everything through WiFi as a Service.

The first option might work for large companies with big budgets who want to own their own infrastructure.

However, the second option is what we really recommend, because it addresses the relatively short life cycle of a high-quality wireless network and the devices that are connecting to it.

WiFi is no longer “optional extra” when it comes to providing connectivity to employees or consumers. Companies now consider it critical to business operations, and are now turning to outsourced providers to ensure nothing is left to chance when it comes to ensuring the quality of service—even if that means bypassing the traditional networking and IT departments.

Wifi support

Want to know the importance of Wifi Support ? Increase Customer Satisfaction. Customers view WiFi access at your business as a necessity.  More than merely meeting a common customer expectation, in-store wireless internet access.

One of the biggest benefits of offering free WiFi is that it increases the time spent on premises. Consumers tend to stay longer if they can use their tablets and laptops via WiFi. support Of the businesses surveyed, almost 62 percent said that customers spent more time in their shop or facility once WiFi was introduced.

The Business Benefits Of WiFi.. Businesses that offer WiFi access to visitors are seeing higher sales and customer satisfaction, while WiFi at the business drives employee productivity and collaboration. Productivity and Collaboration. Employees rely on WiFi more than ever to perform their jobs and stay productive.

manage wifi router

A router is a device that communicates between the internet and the devices in your home that connect to the internet. As its name implies, it “routes” traffic between the devices and the internet.

With the right kind of router in your home, you may be able to enjoy faster internet service, help protect your family from cyberthreats, and avoid those maddening Wi-Fi dead spots.

You don’t have to be a computer genius to know what a good router has to offer. All it takes is to know what you need it for. Understanding how routers work will help you choose the right equipment for your home.

Manage Wifi Router technology has changed over time. Make sure you have a router that uses the latest technology and has updated firmware. MU-MIMO is one such new technology. It stands for multi-user, multiple-input, multiple-output technology. It allows Wi-Fi routers to communicate with multiple devices simultaneously. This decreases the wait time and improves network speed.

wifi monitoring tools

In today’s world an IT organization, you’ve seen wireless networks quickly evolve from a convenience offered to employees to a mission-critical component of your IT infrastructures. Wireless users now expect comparable performance and availability to wired networks.

Organizations enjoy the flexibility of Wi-Fi network access; however, it poses a host of challenges for network managers. Most managers lack the tools and visibility to effectively monitor their wireless networks, much less make informed planning decisions and proactively manage their performance.

Monitoring wireless performance is more complex than wired networks. The range of wireless access points (APs) can be affected by a number of issues, including building materials. As more users connect to a wireless access point and it is oversubscribed, performance begins to degrade. And as APs age, their performance begins to decline.

The Manage Engine Wi-Fi Analyzer and Surveyor can be used to effectively monitor signal strength and display channel graphs on all available Wi-Fi networks. You can use the Wi-Fi monitoring tools to detect slow Wi-Fi networks and identify channel interference and poor signal strength.
