COMPUTER NETWORKS

Computers are used to generate information. Generated information is not useful in itself. The information must be delivered to the right person at the right time. Often information must be transmitted from one location to another. This process is called data communication. Here, we will be concerned with the hardware, software and procedures used in data communication.

LAN: local area networks are privately owned networks within a single building of up to a few kilometers in size. LANs are widely used to connect PCs and workstations in company offices to share resources and exchange information.

A network is any collection of independent computers that communicate with one another over a shared network medium. A computer network is a collection of two or more connected computers. When these computers are joined in a network, people can share files and peripherals such as modems, printers, tape backup drives, or CD-ROM drives. When networks at multiple locations are connected using services available from phone companies, people can send e-mail, share links to the global Internet, or conduct video conferences in real time with other remote users.

Resumen: El análisis etnoarquológico de algunas tradiciones recientemente estudiadas como documentos históricos de la Hispania Celta ha puesto de relieve el gran potencial que encierran las tradiciones de origen prerromano conservadas en el folklore hispano, probablemente, uno de los más ricos y mejor conservados de Europa Occidental.

When Vedic Aryans arrived in India, indigenous folk religion was thriving. Vedic Aryans borrowed freely many local deities adorning Vedic characteristics. At the same time, the Samana culture of thinkers and ascetics was flourishing almost everywhere. The ultimate aim of these thinkers was to win over the bad qualities of the mind, thus, the movement was also named Jina, victors over inner disorders and to see the world with equanimity, thus called Samana. The ultimate aim of yoga, though divided into many sects, remains the same as was determined by the ancestors. The spiritual quests of ascetics had invented means to attain ultimate bliss; Vrata (Yoga) was one, though they might have decided on spiritual destinations differently. The thinkers who thought of the equanimity of all living beings caused a cultural movement that is known to us as Samana culture.
