Certificates for computer network professionals

Several organizations and technology providers offer professional certification, which can be just as useful as a university degree. Those wishing to demonstrate general networking knowledge could obtain CompTIA Network + or Security + credentials. In addition, professionals working with specific network hardware or software can demonstrate a vendor's technological know-how by obtaining entry-level and advanced certifications, such as a Microsoft Certified Technology Specialist or a Cisco Certified Network Specialist. Cisco has several certification and training programs. These are listed as applicant, specialist, collaborator, expert, expert and architect. A list of certificates is specified under each of these addresses.

how to setup wifi lan network

Each computer that will connect wirelessly to the network will need to have a wireless network card installed. If you don't have a free slot in your PC or if you don't feel like opening your computer, there are many different wireless USB adapters available. While not critical, choosing a router / network card combination from the same brand can make setup much easier, as well as allow you to take advantage of the special features that may be included in the devices. At the very least, make sure you choose a router / adapter combination that uses the same wireless protocol. The wireless protocol essentially determines how quickly devices are able to communicate with each other. The most commonly used protocol today is 802.11g, which, at 54 megabits per second, is faster than the older 802.11b. 802.11n is just starting to become more common, even if only for very specific applications. It is very expensive and your average wireless network cannot take advantage of its speed.

 

Safety

Security is the most overlooked step in building a wireless network. Since wireless signals can penetrate through walls and floors, anyone with a wireless laptop can connect to the network. Once connected, they can root your shared files and even introduce viruses to your PCs. Fortunately, it's really easy to secure your network.

There are 2 types of security offered by wireless routers. One is a firewall. The other is encryption. They can be used simultaneously.

 

Encryption, which decides who can use the wireless connection and who cannot, has two common types: WEP and WPA. Without getting super technical, WEP requires users who want to access the network to enter a specific key code, while WPA requires users to tell the network who they are and request a key code for access. The differences are pretty technical, but to simplify it I'll put it like this: WEP is the old style and will definitely prevent occasional passersby from accessing your network, while WPA is newer and will stop even the smartest hacker. The level of security you want will determine which type you choose to use.

how to access lan device from internet

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.

 

 

 

 

 

 

 

 

 

 

 

 

 

how to access lan

In recent years, wireless solutions have become popular in home networking. Like wired solutions, a number of wireless technologies are available to support two major computer networks.

 

WI-FI LINKS

A Wi-Fi connection can cover longer distances than wireless alternatives. Many new computers, especially laptops, have built-in Wi-Fi capability, which is often the preferred option. Wi-Fi can be used with or without a network device. On two computers, it is easy to set up a negative Wi-Fi network device (also known as ad hoc mode).

 

BLUETOOTH LINKS

Bluetooth technology supports extremely high-speed wireless connections between two computers without a network device. Bluetooth is used when the consumer connects to the computer with mobile devices such as a mobile phone.

Most desktop computers and older computers do not have Bluetooth functionality. Bluetooth works best when both devices are in a room close to each other. If you’re interested in networking with mobile devices and your computer doesn’t have Wi-Fi, consider using Bluetooth.

 

Infrared links

A few years before Wi-Fi or Bluetooth technologies became popular, laptops had access to the infrared network. Infrared communication works between two computers, requires no assemblies, and is very fast. Because it’s easy to set up and use, consider an infrared connection if your computers support it and you don’t want to make an effort to connect to Wi-Fi or Bluetooth.

how to connect a wireless router to a lan network

Depending on your network environment and what you want to achieve, there are at least four ways to set up file sharing in Windows 10. You can use the Public folder, a special configuration that allows you to share files on a local network without configuring files. permission. Or you can share your content using the File Sharing feature in Windows 10. And if you want to share files with other people on the Internet, you can use file sharing with OneDrive.

In previous versions, you could also use Homegroup, which is no different from the Public folder, to automatically share your Windows 10 library folders (Pictures, Videos, Music, Documents), Printers, and other devices connected to your computer. However, this is not a feature in Windows 10 anymore.

 

This guide will teach you how to share files over a network using File Sharing and OneDrive in Windows 10. (Although Homegroup is no longer available in the latest version of Windows 10, the steps to use the feature will remain available, as it was still a feature in previous versions. .)

how to create a lan network in windows 7

To set up a small network, you need a router and modem and how to connect them. Every computer also needs an adapter. An adapter is a device that allows a computer to communicate with a router. Almost all computers sold today have built-in Ethernet (wired) interfaces. Ethernet cables look like oversized phones. Most laptops today have built-in wireless interfaces.

Don’t worry, you don’t have to choose one type of network over another, wireless or wireless. Most networks use a combination of both. In fact, most wireless routers also have places where you can connect Ethernet cables, so it’s not uncommon for the main home computer to be connected directly to the router via a wire, and all other computers connected via Wi-Fi.

 

A standard network can look like this: A modem is connected to a telephone line or cable to provide Internet access. It is then connected directly to the router with an Ethernet cable. The router is then connected directly to one computer and at the same time sends a radio signal with which all other computers in the house can communicate with a Wi-Fi interface.

 

Now that all the computers are connected, you need to configure them with Windows to be able to communicate with each other. But don't worry. As I said at the beginning of this article, Windows 7 makes this process incredibly easy.

what is computer networking all about?

Whenever computers are connected to a network, they need protocols to communicate with each other.

If devices want to connect to the Internet, they must use the Internet protocol. There are many networks that are not connected to the Internet and also use Internet protocols, as they are well designed to connect to networks.

However, there are networks that use other protocols that are relevant to their work. Data networks often choose to use network protocols that take advantage of a very close data center structure. This allows data centers to efficiently implement faster algorithms, such as in-depth learning training.

As we move forward with this chapter, we will focus specifically on Internet protocols that enable most computer networks. In the future, networks may use protocols that have not yet been developed. Fortunately, the concepts of Internet-based protocols are important for all network systems.
