| environ. | boundary layer The layer of fluid adjacent to a physical boundary in which the fluid motion is significantly affected by the boundary and has a mean velocity less than the free stream value | muga-geruza |
| environ. | inversion layer The atmosphere layer through which an inversion occurs | alderanzketa-geruza |
| comp., MS | Layer Two Tunneling Protocol | mailako tunel-protokolo (An industry-standard Internet tunneling protocol that provides encapsulation for sending Point-to-Point Protocol (PPP) frames across packet-oriented media. For IP networks, L2TP traffic is sent as User Datagram Protocol (UDP) messages. In Microsoft operating systems, L2TP is used in conjunction with Internet Protocol security (IPSec) as a virtual private network (VPN) technology to provide remote access or router-to-router VPN connections. L2TP is described in RFC 2661) |
| environ. | ozone layer The general stratum of the upper atmosphere in which there is an appreciable ozone concentration and in which ozone plays an important part in the radiative balance of the atmosphere | ozonosfera |
| environ. | ozone layer depletion The fragile shield of ozone is been damaged by chemicals released on earth. The main chemicals that are depleting stratospheric ozone are chlorofluorocarbons which are used in refrigerators, aerosols, and as cleaners in many industries, and halons, which are used in fire extinguishers. The damage is caused when these chemicals release highly reactive forms of chlorine and bromine. Over the past 30 years ozone levels over parts of Antarctica have dropped by almost 40% during some months and a "hole" in ozone concentrations is clearly visible in satellite observations | ozonosferaren urritze |
| comp., MS | Secure Sockets Layer | Socket seguruen geruza (The protocol that improves the security of data communication by using a combination of data encryption, digital certificates, and public key cryptography. SSL enables authentication and increases data integrity and privacy over networks. SSL does not provide authorization or nonrepudiation) |
| environ. | soil layer Distinctive successive layers of soil produced by internal redistribution processes. Conventionally the layers have been divided into A, B and C horizons. The A horizon is the upper layer, containing humus and is leached and/or eluviated of many minerals. The B horizon forms a zone of deposition and is enriched with clay minerals and iron/aluminium oxides from the A layer. The C layer is the parent material for the present soil and may be partially weathered rock, transported glacial or alluvial material or an earlier soil | lurzoru-geruza |
| comp., MS | Transport Layer Security | garraio-geruzaren segurtasun (A protocol that provides communications privacy and security between two applications communicating over a network. TLS encrypts communications and enables clients to authenticate servers and, optionally, servers to authenticate clients. TLS is a more secure version of the Secure Sockets Layer (SSL) protocol) |
