8. ______ - an interconnected or intersecting configuration or system of components

Ex. VII 1- assets; 2- terrain; 3- Bandwidth; 4- fault tolerance; 5-rack; 6- black box; 7- backplane; 8- network;

VIII. The abstract explains centralized architecture which is considered to be the First Generation Architecture. Fill in the gaps with the proper forms of the words given in the brackets.

As the __1__ (digit) technology evolved, a central __2__ (compute) was added to integrate the __3__ (inform) from the sensors and subsystems. The __4__ (centre) computing complex is connected to other subsystems and sensors through analog, digital, synchro and other interfaces. When interfacing with computer a __5__ (vary) of __6__ (differ) __7__ (transmit) methods, some of which required signal __8__ (convert) (A/D) when interfacing with computer. Signal conditioning and __9__ (compute) take place in one or more computers in a LRU located in an avionics bay, with signals transmitted over one way data bus.

Ex. VIIi 1- digital; 2-computer; 3- information; 4-central; 5- variety; 6-different; 7- transmission; 8-conversion; 9- computation;

IX. Your friend was given a task to write a short article about National Aerospace Laboratory and its projects. He asked you to read the article and correct the mistakes where it is necessary.

Space Qualified Avionics N

The National Aerospace Laboratory (NLR) is the key center of expertise for aerospace technology in Netherlands. NLR has extend experience in design, production and testing of space electronics, which is subject to stringent demands on processes and procedures specific for space applications. Examples of space electronics projects range for very small to large multiple board assemblies for scientifical and operational applications. NLR develop scalable hardware and software systems, primarily for earth observation missions. This technology becomes increasing important due ever growing data rates produced by state-of-the-art sensors and limitations on data link bandwidths. Space electronics must produced under well controlled conditions. Extreme conditions survival and operation of space electronics can be tested at the NLR facilities for space electronic. NLR operates a space vacuum simulator, a climate chamber and a clean room facility for handle flight equipment.
