4.1.1 Space problems Probably the best known of these is the fact that the internet is running out of space for identifying computers. Each computer in a network needs to be identified by a unique data pattern known as an IP address. The current technology used to transport data around the internet is such that in the comparatively near future we shall run out of space to hold these unique addresses. Happily this is a problem that has been identified and groups of researchers around the globe have developed new t
7.2 Should I unsubscribe from mailing lists? Many spam messages have a line at the bottom offering to unsubscribe you from a mailing list, but you should be very wary of doing this. Quite often the senders of the spam will use the 'unsubscribe' option to verify that your email address is live. They may then sell your address to other people for use in spamming. So using the unsubscribe option can increase your spam rather than reduce it. Our advice is never to use the unsubscribe option unless the mail you receive is from a well-known,
Introduction This unit is an adapted extract from the course Pure mathematics
(M208) The idea of vectors and conics may be new to you. In this unit we look at some of the ways that we represent points, lines and planes in mathematics. In Section 1 we revise coordinate geometry in two-dimensional Euclidean space,
Introduction This unit is on Christopher Marlowe's famous play Doctor Faustus. It considers the play in relation to Marlowe's own reputation as a rule-breaker and outsider and asks whether the play criticises or seeks to arouse audience sympathy for its protagonist, who sells his soul to the devil in exchange for 24 years of power and pleasure. Is this pioneering drama a medieval morality play or a tragedy? This unit is an adapted extract from the Open University courseAuthor(s):
3.2 What does a processor look like? So what do these devices that are manufactured in such vast quantities look like? Processors are manufactured as integrated circuits. Essentially they are circuits, around the size of a fingernail, which contain many millions of electronic components manufactured as one very complex circuit. Figure 4(a) shows how a processor manufactured as an integrated circuit is packaged so it can be used as a component in an electronic circuit. The pins of the package are connected to the integrated circu
America: The Story of Us, Episode 1 - 'Rebels'
From Jamestown to Plymouth, early settlers fight for survival. Tobacco sows the seeds of opportunity; the north becomes a powerhouse of trade. Tension, taxation and resistance explode into war as the rebels take on the might of the British Empire. Washington's army is near defeat, but new weapons and battle tactics turn the tide. Forged through revolution, a new nation is born. (45:57)
1.2 The growth of the legal system The legal system plays a significant and growing role in society as our lives become governed by an increasing number of laws. As our society has become more sophisticated, a greater number of laws have been required. This in turn has resulted in our legal system becoming increasingly more complex. Changes in technology, the way in which we live and the types of relationships we have are all reflected by the law. Society expects the law to reflect its ideas, values and culture, so the law has

The Lamont-Doherty Earth Observatory Deep-Sea Sample Repository archives sediment and rock deep-sea core data for marine geology and oceanographic research and education. Students can learn about the process of taking the cores, the characteristics of the specimens collected, and their benefits. Researchers can search over 300 datasets for cores sites, mineralogy, micropaleontology, and other core data. Scientific investigators can find out how to obtain samples from the cores.
