question: Wi-Fi or WiFi () is a technology for wireless local area networking with devices based on the IEEE 802.11 standards. "Wi-Fi" is a trademark of the Wi-Fi Alliance, which restricts the use of the term "Wi-Fi Certified" to products that successfully complete interoperability certification testing.

Devices that can use Wi-Fi technology include personal computers, video-game consoles, phones and tablets, digital cameras, smart TVs, digital audio players and modern printers. Wi-Fi compatible devices can connect to the Internet via a WLAN and a wireless access point. Such an access point (or hotspot) has a range of about indoors and a greater range outdoors. Hotspot coverage can be as small as a single room with walls that block radio waves, or as large as many square kilometres achieved by using multiple overlapping access points.

Wi-Fi most commonly uses the UHF and SHF ISM radio bands. Having no physical connections, it is more vulnerable to attack than wired connections, such as twisted pair.

In 1971, ALOHAnet connected the Hawaiian Islands with a UHF wireless packet network. ALOHAnet and the ALOHA protocol were early forerunners to Ethernet, and later the IEEE 802.11 protocols, respectively.

A 1985 ruling by the U.S. Federal Communications Commission released the ISM band for unlicensed use. These frequency bands are the same ones used by equipment such as microwave ovens and are subject to interference.

question: Albanians () are a nation and ethnic group, native to Albania, Kosovo and other countries who share a common culture, ancestry and speak the Albanian language as a native tongue. Legally, the term is used to refer to the citizens of the Republic of Albania. Ethnic Albanians speak the Albanian language and more than half of ethnic Albanians live in Albania and Kosovo. A large Albanian population lives in Greece, Italy, the Republic of Macedonia, with smaller Albanian populations located in Serbia and Montenegro.

Albanians produced many prominent figures such as Skanderbeg, leader of the medieval Albanian resistance to the Ottoman conquest and others during the Albanian National Awakening seeking self-determination. During the 17th and 18th century Albanians in large numbers converted to Islam, often to escape higher taxes levied on Christian subjects as well as a plethora of other reasons including ecclesiastical decay, coercion by Ottoman authorities in times of war, and the privileged legal and social position of Muslims. As Muslims, some Albanians attained important political and military positions within the Ottoman Empire and culturally contributed to the wider Muslim world. Albania gained its independence in 1912 and between 19451992, Albanians lived under a repressive communist regime. Albanians within Yugoslavia underwent periods of discrimination and eventual self-determination that concluded with the breakup of that state in the early 1990s culminating with Albanians living in new countries and Kosovo. Outside the southwestern Balkans of where Albanians have traditionally been located, Albanian populations through the course of history have formed new communities contributing to the cultural, economic, social and political life of their host populations and countries while also at times assimilating too.

2. at least how many do?
3. what is their mother tongue?

question: There was once a small town by a river. There were many houses in this town and they were all different colors, shapes and sizes. which made the people happy. On one street there was a red house, a green house, a blue house and one purple house with yellow stripes. The people in the town were all very friendly and knew each other well.

When the people of the town went out they loved to wear hats but never wore shoes and the hats were also many different colors, shapes and sizes. On Sundays all the families in town would go to the park by the river and have picnics. The children would run, skip and play and the parents would talk, eat and laugh. The children loved the picnic foods they had. There were hot dogs, hamburgers, chicken and steak. They also had salads, coleslaw, fries and chips. The kids' favorite was hamburgers with fries.

On days when it rained the children and parents would stay inside and read or color pictures and drink hot chocolate and they loved to wear big warm sweaters. At night the family would all go to the kitchen and cook dinner together and after dinner was finished they would all clear the table and clean the dishes together before getting ready for bed. They would put their pajamas on but never wear socks and they would get under the covers and fall asleep.
