Special forces

Special forces and special operations forces are military units trained to perform unconventional missions. Special forces, as they would now be recognised, emerged in the early 20th century, with a significant growth in the field during the Second World War.

Depending on the country, special forces may perform some of the following functions: airborne operations, counter-insurgency, "counter-terrorism", covert ops, direct action, hostage rescue, high-value targets/manhunting, intelligence operations, mobility operations, and unconventional warfare. The term “special forces” in the US refers to the US Army's forces while the term “special operation forces” refers to all units. In Russian-speaking countries special forces are typically called spetsnaz, an acronym for "special purpose". Likewise Russian speakers refer to special forces of other nations as spetsnaz, for example US Special Forces would be referred to as Amerikanski spetsnaz in Russian.

The North Atlantic Treaty Organization (NATO /ˈneɪtoʊ/; French: Organisation du traité de l'Atlantique Nord; OTAN), also called the North Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defense in response to an attack by any external party. NATO's headquarters are located in Haren, Brussels, Belgium, where the Supreme Allied Commander also resides. Belgium is one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009. An additional 22 countries participate in NATO's Partnership for Peace program, with 15 other countries involved in institutionalized dialogue programmes. The combined military spending of all NATO members constitutes over 70 percent of the global total. Members' defense spending is supposed to amount to 2 percent of GDP.

Channel Link

Channel-Link (C-Link) by National Semiconductor is a high-speed interface for cost-effectively transferring data at rates from 250 megabits/second to 6.4 gigabits/second over backplanes or cables. National Semiconductor introduced the first Channel-Link chipsets in the late 1990s to provide an alternative to continually widening data buses to get higher throughput.

Channel-Link uses LVDS, and comes in configurations with three, four, or eight parallel data transfer lanes plus the source-synchronized clock for each configuration. In cable applications, it uses one twisted pair in order to transmit a clock signal, and on the remaining differential pairs it transmits digital data at a bit rate that is seven times the frequency of the clock signal. The backplane applications work the same way except for using differential traces instead of twisted pairs.

The three Channel-Link chipset configurations provide varying user interfaces. For example, the three-lane chipset has 21 single-ended inputs and outputs for the user interface, and the four-lane chipset has 28 single-ended inputs and outputs. The eight-lane chipset has 48 single ended inputs and outputs because it uses one of the 7 serialized bits/lane to DC-balance the other six bits.
