What are the key aspects to achieving acceptable usability outcomes for information systems being developed? The changing technologies and increased usage across the general population, the impacts of this in our everyday lives, at work and at leisure are exponentially increasing. The interfaces and interaction styles presented as part of these technologies have been challenged to be more intuitive, contextually sensitive, location aware, human centred and aimed at a larger community of stakeholders.

What is Inter-VLAN RoutingWhat is Inter-VLAN Routing? Each VLAN is a unique broadcast domain. Computers on separate VLANs are, by default, not able to communicate. Each VLAN is a unique IP subnetwork. To allow VLANs to communicate, we need a router to communicate among separate broadcast domains and unique IP subnetworks. Inter-VLAN routing, then, is a process of forwarding traffic from one VLAN to another VLAN using a router.

IN THE NEAR FUTURE an attempt to translate from a foreign language by machine will be made at the computational laboratory of Birkbeck College. It will differ from previous experiments in that the sentences or passages of French to be translated will not have been specially chosen or "doctored" in any way beforehand: on the contrary, they will be constructed by French scholars, who will be invited to do their best to fault the machine. What follows is an account of the method, or program, which makes such an experiment possible. ...

Up to this point we have seen: Classical Crypto Symmetric Crypto Asymmetric Crypto These systems have focused on issues of confidentiality: Ensuring that an adversary cannot infer the original plaintext message, or cannot learn any information about the original plaintext from the ciphertext. In today’s lecture we will put a more formal framework around the notion of what information is, and use this to provide a definition of security from an information-theoretic point of view.

What are the rules governing when to and not to give out security credentials In this lecture, we will look at the broad area of secure and trusted systems We will focus on access control models These methods are often used to abstract the requirements for a computer system But, they hold for general systems where security is a concern (e.g. networks, computers, companies…) ...

Concept of User Interface The user interface is the part of the system that you see, hear and feel (look and feel) Other parts of the system are hidden to you, for instance the database where information is stored. Although users don’t see the hidden parts, they imagine to some extent what is going on ’behind the screen’. Examples When you use a computer, you give it orders, usually by means of the mouse and the keyboard. The computer replies, usually by showing something on the screen or making sounds.
