Description of your home town

Urgench is a small town in western Uzbekistan, the center of Khorezm region and transport hub for the entire area. It can serve as a great starting point for travel in Western Uzbekistan for anyone looking to explore the farther reaches of the country. Just thirty kilometers southwest of Urgench is the ancient city of Khiva, which some have likened to a live museum. Fifty kilometers to the north you’ll find the ruins of several thousand-year-old fortresses, including Toprak-Kala, Kyzyl-Kala and Ayaz-Kala.

The city of Urgench, Uzbekistan should not be confused with Kunya-Urgench in Turkmenistan. Kunya-Urgench was once a thriving city on the banks of the Amu-Darya, but the city began to die. Amu-Darya then founded New Urgench there in 1646, and in 1929, the New Urgench began to simply be called Urgench.
In Urgench there are no historical or cultural attractions, and the city serves mainly as a transport hub – there’s a railway station and an international airport, to which regular flights from Tashkent and Moscow are made. From Urgench tourists in Uzbekistan can easily travel to Khiva, to the fortresses of Khorezm, to Dashoguz (Turkmenistan) and further on to Kunya-Urgench.

a) COMPUTER HARDWARE

Hardware refers to the physical, tangible computer equipment and devices, which provide support for major functions such as input, processing (internal storage, computation and control), output, secondary storage (for data and programs), and communication.

HARDWARE CATEGORIES (Functional Parts)
A computer system is a set of integrated devices that input, output, process, and store data and information. Computer systems are currently built around at least one digital processing device. There are five main hardware components in a computer system: Input, Processing, Storage, Output and Communication devices.

1. 
   INPUT DEVICES
   

Are devices used for entering data or instructions to the central processing unit. Are classifie according to the method they use to enter data.
a) KEYING DEVICES

i) The keyboard

Keyboard (similar to a typewriter) is the main input device of a computer . It contains three types of keys-- alphanumeric keys, special keys and function keys. Alphanumeric keys are used to type all alphabets, numbers and special symbols like $, %, @, A etc. Special keys such as , , , , etc. are used for special functions. Function keys such as , , etc. are used to give special commands depending upon the software used e.g.F5 reloads a page of an internet browser. The function of each and every key can be well understood only after working on a PC. When any key is pressed, an electronic signal is produced. This signal is detected by a keyboard encoder that sends a binary code corresponding to the key pressed to the CPU. There are many types of keyboards but 101 keys keyboard is the most popular one.
How the keys are organized
