Both of the following: 1. Provide the definition for Access Control Lists (ACL) and how they are used on servers and on a network. Explain any similarities and differences in how ACLs are used. Research and describe at least two outside references that discusses ACLs and their use for security. 2. Provide an example of how a packet travels from a host computer and is routed by a router. You should provide a basic overview of what steps are involved in the routing of the packet to its final destination.
and motivating environment and a number of objects to play with. However a child who is at the concrete operational stage should be provided with activities in which they can classify problems, order and location of concrete objects. This allows the adult to see the different explanations the children at different stages of cognitive development will come up with. The activities or situations given should engage the learners and requires adaptation such as assimilation and accommodation. The learning materials given to the children should be relevant and should involve the right level of motor or mental operations for a child depending on his/her age (McLeod, S.A. 2007). Another critic of Piaget is that he used his own three children for many of his experiments and observations not thinking about the culture they came from (Smith, et al 2003, p. 412). Due to this he failed to take children from different backgrounds into account. A larger sample with children from various backgrounds should have been used to get a more accurate and generalised result. Piaget’s theory received a number of critic’s however his work had a major influence in the education sector. He disliked the idea of children being taught sat at desks, listening and transmitting information the teacher gives. Piaget believed that children learn through discovery, the task should be set by the teacher and children should be left to discover, any mistakes the children make should provide useful information on the child’s cognitive development. Also for the correct answers, the process of how the child worked out the correct answer should be investigated (Smith et al, 2003, p.388). The curriculum is set out in a sequence, particularly in the core subjects such as mathematics and science. This is influenced by Piaget’s theory. The choice of learning objectives, curriculum sequencing, grade placements of topics, the assessment of children’s intellectual functioning and teaching methodology (Murray, 1985, p.291) It is important that the class teacher knows at what stage of cognitive development each child is at as it is an important aspect in Piaget’s theory. This also has an impact on pedagogy as teachers have to change their teaching style to enhance the child’s development. The second theorist i will be critically analysing is Lev Vygotsky (1896-1934). He was born in Russia in the same year as Piaget. He studied law and graduated at Moscow University. He then went on the study a Ph.D in Literature and Linguistics. Vygotsky’s began to work in psychology after the Russian revolution where the Marxism replaced the rule of the czar. The new Marxist philosophy emphasised socialism and collectivism. Individuals were expected to give up their personal goals and achievements to improve the society as a whole by sharing and co operation. The success of an individual was see>GET ANSWER
