At the basic capacity level, the computer networking experts were able to respond to the call and email solutions of network users. They need to be able to find and offer repair instructions remotely and in person as well. In an advanced role as an analyst or administrator, computer networking experts often monitor network access for bottlenecks, security threats, or connectivity issues. They can also configure and maintain security tools to ensure the security of a company's software, systems and data.

how to create lan network using wifi

A local area network (LAN) is a group of computers and peripherals that share a common line of communication or wireless connection to a server in a specific area. A local area network can only serve two or three users in the home office or thousands of users in the company's head office. Homeowners and IT (IT) executives have set up LANs so that network nodes can communicate and share resources such as printers or network memory.

 

LAN requires Ethernet cable and Layer 2 switches as well as devices that can connect and communicate over Ethernet. Larger LANs often include layer 3 switches or a way to simplify traffic flow.

 

LAN allows users to connect to internal servers, web pages, and other LANs that belong to the same broadband network (WAN). Ethernet and Wi-Fi are the two main ways to enable LAN connections. Ethernet is a specification of the Institute of Electrical and Electronics Engineers (IEEE) that enables computers to communicate with each other. Wi-Fi uses 2.4 GHz and 5 GHz spectrum radio waves to connect computers to local area networks.

Abandoned LAN technologies, including the Fiber Distribution Interface (FDDI) and the Connected Source Computer Network (ARCNET), have lost their popularity as Ethernet and Wi-Fi speeds have increased and connection costs have dropped.

 

Understanding the local area network

There are two main types of LAN: WLAN and WLAN. LAN-connected LAN uses switches and Ethernet cables to connect Internet of Things (IoT) endpoints, servers and devices to corporate networks. For small businesses with very few devices, a LAN port can consist of a single uncontrolled LAN switch with a sufficient Ethernet port to connect all devices. But larger LANs, which connect thousands of devices, require additional hardware, software, and setup steps to ensure the best network performance. This is where the term virtual network (VLAN) comes into play.

Choose a router if your provider has not provided it to you; it's cheap ($ 40 to $ 80) and saves you days of hair pain because it keeps most worms out of your network. With a router, none of your computers have to worry about connecting to the internet - the router handles it.

 

The routers are available in both wired and wireless versions. The wired versions have a variable number of sockets, the wireless ones have a socket for the modem cable, an antenna for the wireless network, and usually a few sockets for routing cables to computers in the same room.

 

For some perverse reason, wireless routers are generally cheaper than wired ones, although wireless ones include everything that wired ones do plus wireless radio. So get yourself a wireless router. If you need more jacks than your router has, get a cheap switch as well; run a cable from one of its jacks to one of the jacks on your router and it'll all be one big happy network.

Rent or buy?

Many providers will offer you to rent a modem, router, or both, typically for the low, low price of $ 5 per month each. This is rarely a good deal. You can buy your router or modem at a large box store for around $ 75, and some arithmetic calculations reveal that you'll be saving money after a year and a half. The technology of modems and routers is slowly changing, and the ones you get now should serve you for five years or more.

 

If you have a DSL service from the telephone company, they will invariably provide the modem at no additional cost because it must match whatever DSL equipment you use eventually. Cable modems, on the other hand, are fully standardized using a specification called DOCSIS. The only question is whether to get DOCSIS version 2 or 3, with the answer 3 because it is faster.

What is a LAN?

 

LAN stands for local area network. A LAN is a group of computers and devices that are in a specific location. Devices connect to the LAN with an Ethernet cable or via Wi-Fi. Your home may have a LAN. If your computer, tablet, smart TV, and printer are connected wirelessly over Wi-Fi, these connected devices are part of your LAN. Only your devices have access to your LAN.

 

Some history on LAN

LANs were first used by colleges and universities in the 1960s. These computer networks were used to catalog library collections, record classes, record student grades, and share equipment resources.

 

Business groups did not like LANs until Xerox developed PARC Ethernet in 1976. The first commercial use of this new technology was Chase Manhattan Bank in New York City. In the early 1980s, many companies had an Internet network (intranet) with hundreds of computers sharing printers and storing files in one place.

After the release of Ethernet, companies such as Novell and Microsoft developed software products to manage these Ethernet LANs. Over time, these network devices became part of popular computer operating systems. Microsoft Windows 10 has tools for setting up a home network.

 

LAN functions

LAN is available in many sizes. A LAN is a group of devices connected through a home Internet connection. Small businesses have local area networks that connect a dozen computers to printers and file storage. Most LANs are managed by a server that stores files, shares data between devices, and routes them to printers and scanners.

how to setup a wireless lan network

The Network and Sharing Center in Windows 7, 8 and 10 is one of the most important and useful Control Panel apps that allows you to view information about your network and allows you to make changes that affect its operation. you can access network resources.

 

Unfortunately, most people don't work online because they don't understand what everything means and are afraid to pick up something. However, once you understand the options, you can troubleshoot on your own, increase your privacy, and quickly share files and printers between multiple computers.

 

At the top, you'll see the active network (s), network type, login type, homegroup information, and connection information. The first thing to understand about this information is the network type, which is listed directly under the network name.

In the examples above, one home network is listed and the other has a private network. This is very important because when you are connected to a private or home network, there are many sharing settings that are basically set for reliability. This means that others can access your computer on the network, perhaps access shared folders, stream multimedia content from your computer, and so on.

 

Windows will usually attempt to do this automatically for you so that you can use the public profile and not the private one when connecting to a public WiFi network. Sometimes Windows asks you if you want to enable sharing or search tools once connected to a network and if you say yes, it makes the network private. If you don't select it, it will make the network public.

 

You can also change the network type to Public or Private depending on the type of privacy you want. This can be useful, for example, if you are visiting someone and want to make sure that no one can access the data on your computer while you are connected to their network. Change the network type to Public and no one will be able to find your computer on the network.

Evaluate the types of networks

Many small businesses use a network to share Internet access, printers, and files from one computer to another. While networking is almost certainly a boon to your business, you need to decide which type of network is the best choice for your business based on its specific and unique needs. Your options are wireless, wireless, and hybrid networks. When choosing a network for your business, you should consider two key points: where your equipment is and how fast you want your network to be. While the costs are similar between the different types, the prices vary depending on the speed of the network chosen.

The following sections describe the various network options available.

 

Wireless networks

Wired or Ethernet networks can transfer data from 10 Mbps to 1000 Mbps, depending on the type of cable used. Gigabit Ethernet provides the fastest transfer rate up to 1 gigabit per second (1000 Mbps).

 

Benefits

Ethernet networks are very secure and fast.

Ethernet networks are more secure than wireless networks because they are full.

Objects or walls are not affected by Ethernet networks.

create a lan network windows 10

I'm using windows from version 98 and have started sharing files and playing through Local Networks with Windows XP, from there it becomes more difficult to design a LAN with each new version of Windows, yes . It's as if Microsoft is taking away their users. from this feature and now with the latest version of Windows 10 they have succeeded, it is impossible to make any kind of network local (perhaps for a printer), before I do the random steps to make it work:

create a lan network windows 10

Changing IP addresses

Generates a password for each user

Restarting millions of times the computers

Allows access to all types of networks (public and private)

Sharing primary hard drives

...

and secretly it works, with windows 10 it's another tricky story, sometimes only the first PC appears on the second PC, sometimes the other way around, sometimes they don't show up at all and the most mythical mistake is when I try to connect with the other. PC and I receive a message telling me that I can incorrectly identify identifiers, such as forgetting a password I use frequently or not being able to copy the username.

 

See, I beg you, I only need 2 things, information on why Microsoft is making such a thing so difficult and is there a basic way to create a proper Local Network at least to play with my brother of some games.

what is the difference between computer network and internet?

The essential difference between a network and the Internet is that the network is made up of computers that have a physical connection and can be used as personal computers and share information with each other. On the other hand, the Internet is a technology that connects these small and large networks and builds a larger network.

 

Network definition

A network is a collection of interconnected autonomous computers. These linked computers can share information with each other. However, these systems also work independently. A computer network is a product that we obtain by combining two technologies which are computers and communication. As a result, this combination of computer and network culminates in providing a unified system that distributes all types of data and information. Data communication and data processing are different. Likewise, there is no significant difference between data, voice and video communication.

what is the difference between computer network and internet

Key networking technologies are designed and engineered for a specific purpose. For example, different organizations manage their own network that connects different departments and personnel systems of that organization. Therefore, each organization and company selects the appropriate hardware technology for their specific communication and budget needs.

 

Furthermore, it was inconvenient to build a universal network technology because a single network cannot serve all needs. Some applications require high-speed networks to connect computers in a building. Economical technologies that meet the requirement of covering large geographical distances and low-speed network connection devices cannot be located very far apart.
