GEOGRAPHY A LEVEL EDEXCEL PAPER 2 Globalisation - ANS The growing interdependence of countries, people and cultures worldwide through increasing connections including trade in goods and services and flows of capital, technology and ideas/ Shrinking world - ANS Although physical distances around the world are unchanged, technology has massively reduced the time it takes to trade, travel, and communicate globally. Transport developments for globalisation - ANS - Railways - Aircraft - Containeri...

A1) Benefits of pentesting -ANSWER Manage risk. Increase business continuity. Minimise client-side attacks. Protect clients, partners and third-parties. Comply with regulation. A1) Pentest structure -ANSWER Reconnaissance (i.e. find live hosts, sweeping, find services, scanning, banner matching, find vulnerabilities). Target prioritisation (e.g. assess servers rather than printers). Testing of services and exploitation if applicable. Consult/Confirm with customer if ok to exploit. Inform cust...

AQA AS Physics Chapter 5 Optics LATEST UPDATE Normal Imaginary line perpendicular to the boundary between two materials or a surface. Partial reflection When some of the wave bounces off a surface, as it does when light moves from air to a refractive substance. Refractive index Ratio of sin i to sin r. Also the ratio of the speed of light in a vacuum to the speed of light in the material. Also the ratio of the wavelength of light in a vacuum to the wavelength of light in the material. ...
