In computer networking everything begins with the physical layer, which for many years was copper wire. The physical layer was broadened to include anything that represent the wire, such as fiber optic cable, infrared or radio spectrum innovation.
Wireless network describes any kind of computer network that is not linked by cables of any kind. While mobile phone technology is often discussed as a type of wireless networking, it is not the same as the wireless regional location network (WLAN) innovation discussed right here.
What is Wi-Fi?
As is typically the case in innovation, the marketing definition is not exactly the like the technical spec.
The term Wi-Fi has actually commonly been used as a technical term to explain wireless networking. Wi-Fi is in fact a hallmark of the Wi-Fi Alliance, a trade association that promotes wireless LAN innovation. Producers may use the hallmark to brand products if they are licensed by The Wi-Fi Alliance to conform to certain requirements.
The actual technical requirements for wireless local location network (WLAN) computer system interaction are known as IEEE 802.11. IEEE refers to the Institute of Electrical and Electronic devices Engineers a non-profit expert association formed in 1963 by the merger of the Institute of Radio Engineers and the American Institute of Electrical Engineers.
IEEE 802 refers to a family of IEEE requirements handling networks bring variable size packets, makings it various from cellular phone based networks. 802.11 is a subset of the household specific to WLAN innovation.
A common mistaken belief is that Wi-Fi is an acronym of wireless integrity, it is not. The Wireless Ethernet Compatibility Alliance wanted a cooler name for the new technology as the IEEE 802.11 b Alliance was not all that catchy.
How does Wi-Fi work?
A Wi-Fi made it possible for device such as a desktop computer or computer game console can connect to the Web when within range of a device such as a wireless router connected to the Web. Wireless regional location network (WLAN) technology enables your gadget to link to the router, which in turn links you to the web.
In order to link to the web, you need a unique IP (web procedure) address. On your home network, when your router is linked to the internet, it has a public address, that is the one that deals with the web, and is distinct in relationship of other routers on the web.
Your router likewise has a regional IP Address of something like 192.168.1.2 and this is a private IP address space. Addresses starting with 192.168 can not be transmitted onto the general public Internet and are generally utilized for house local location networks (LANs).
If you have four personal computer, your router produces a house network and the 4 home computers have a special number in relationship to each other. Your regional computer systems link to the router, either by a wire plugged into the router, or through a wireless signal.
Routers are used to create rational borders in between networks, and in this allow a gateway, such as an access indicate the web to be shared. In geek speak terms subnetting can be extremely complex, exactly what is occurring right here is the procedure called subnetting.
Would you allow an overall stranger into your residence and have him utilize your personal computer? If you have actually addressed no to this question, you have quite mentioned your case why you have to enable some type of wireless security.
Wireless security is a subject to itself, and deserves a different short article. The bottom line is, you need to make it possible for some kind of wireless security on your router to keep unfamiliar people from accessing your individual network.
The term Wi-Fi has commonly been made use of as a technical term to explain wireless networking. Wi-Fi is in fact a hallmark of the Wi-Fi Alliance, a trade association that promotes wireless LAN innovation. A common misunderstanding is that Wi-Fi is an acronym of wireless fidelity, it is not. The Wireless Ethernet Compatibility Alliance wanted a cooler name for the new technology as the IEEE 802.11 b Alliance was not all that catchy. The marketing business Interbrand, known for creating brand names, was employed to produce a brand name to market the new technology, and the name Wi-Fi was selected.
