For a UTP implementation in a LAN, you must determine the EIA/TIA type of cable needed and also whether to use a straight-through or crossover cable. This topic describes the characteristics and uses of straight-through and crossover cables, as well as the types of connectors used when UTP is implemented in a LAN.
Surface currents are generated largely by wind. Their patterns are determined by wind direction, Coriolis forces from the Earthâs rotation, and the position of landforms that interact with the currents. Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents.
I'd better tie down my pen! Out on the ocean, the wind is the main culprit in generating these surface movements. The wind creates a current in the surface water; that current is then modified by the shapes of the continents and by the Earth's rotation. If you don't spend much time sailing the great oceans, you might not be familiar with the global patterns of ocean circulation, but sailors have known about them for centuries.
