What different types of technology brought about changes to farming in Texas after the Civil War era? List at least three different types of technology.

After the civil war, there was an emergence of southern farm tenancy, a system of near slavery without legal sanctions with tenant farmers in place of slaves. ... The number of farms in Texas rose from about 61,000 in 1870 to around 174,000 in 1880 and 350,000 by 1900 where farm and ranching enterprises expanded rapidlythe growth of the cotton industry, the development of railroads and the discovery of large quantities of oil were only the first of a series of dramatic transformations that would make the Lone Star State the economic powerhouse it is today.

A combination of unexpected bounty in the form of mineral wealth and other resources, growing integration into the national economy of the United States (which itself underwent its own series of transformations), the growth of the service economy and the high technology industry, and the state's increasingly important geographic position at one of the frontiers of an extensive free trade area that includes Mexico and Canada, have all contributed to the ongoing transformation of the state.

Oil and natural gas production bestowed new economic importance and diversity on the Texas economy. Nevertheless, they only reinforced the state's reliance on the production of so-called "primary goods"--mining (including oil and natural gas production), timber, agriculture and ranching. It would take a World War, followed by a post-war national economic boom, to really build a significant base for industrial production, create several transportation hubs in the new air travel industry, and establish the state as a platform for high technology research and development.

The energy sector is still prominent among Texas industries, as are ranching, agriculture, and agriculture related industries like cotton ginning. But other industries such as airlines, travel and entertainment, and technology (including computers, aerospace, and telecommunications) have grown to considerable prominence.

computers, aerospace, and telecommunications are the three different types of technology.
