by MEG International‚ a large and reputable Finnish IT organisation. This report explains Enterprise architecture and how it can be applied as a strategy. It explains Zachman’s "framework for enterprise architecture" (Zachman‚ 1987) and the components of its two dimensional matrix. Criticism that Zachman framework is only a taxonomy follows on identifying next framework "The Open Group Architecture Framework" (known as TOGAF) and it’s criticism that can act as architectural process rather than a

350CT Coursework Part A: Secure Network Design Introduction Dear XYZ Ltd.‚ My name is Jacob Woodfield and I am writing to you on behalf of Coventry Security Solutions‚ with whom you recently made contact with to request a security audit of your computer systems. Firstly‚ I would like to congratulate you on a very wise choice in deciding to have a security audit take place of your company. Last year 87% of small businesses had a security breach‚ which is up from 76% in 2012. The median number

Network and Cell Information Acquisition When a mobile station is successful in synchronizations it reads four time-slot long Broadcast Control CHannel (BCCH) for the system information. This channel has a specific time-slot relative to the FCCH/SCH channels. The information in the BCCH channel includes: Location Area ID (LAI) o Mobile Country Code (MCC) o Mobile Network Code (MNC) o Location Area Code (LAC) Cell ID (CID) BCCH Allocation List (BA list) – a list of neighboring cells’

BUTTERFLY NETWORK Butterfly network is a network with 2q nodes and q + 1 columns as an unfolded q-cube in order to facilitate the discussion‚ visualization‚ and analysis of hypercube routing algorithms. However‚ a butterfly network can be viewed as a parallel processing architecture in its own right. A butterfly architecture (Fig. A‚ left) has p = 2 q(q + 1) processors of maximum degree d = 4‚ a diameter of 2q = ∪(log p)‚ and a bisection width of ( – 1)2 q+1 + 0(2 q) = ∪(p/log p). A wrapped

THE CASE FOR THE TECTONIC Kenneth Frampton Kenneth Frampton’s ‘Rappel a L’Ordre: The Case for the Tectonic’ identifies the issues in relation to the tectonic form‚ his intention is to make architecture step apart of just being part of a scenographic interpretation. The word tectonic is addressed from its different origins but overall referring to carpentry and its evolution into an aspect of poetry and art of construction. Tectonic objects are seen in two different forms; one being ontological

Computer Architecture The circuitry in a computer which controls the manipulation of data is called the central processing unit‚ or CPU. In the machines of the mid-twentieth century‚ CPUs were large units comprised of perhaps several racks of electronic circuitry that reflected the significance of the unit. However‚ technology has shrunk these devices drastically. The CPUs found in today’s desktop computers and notebooks are packaged as small flat squares (approximately two inches by two inches)

Report on Service Oriented Architecture (SOA) ABSTRACT SOA is a design for linking business and computational resources (principally organizations‚ applications and data) on demand to achieve the desired results for service consumers (which can be end users or other services). Service-orientation describes an architecture that uses loosely coupled services to support the requirements of business processes and users. Resources on a network in a SOA environment are made available as independent

Network Topologies Network topologies are an important part of the network. Without the proper topology‚ the network may not meet the needs of the organization. The layout of a network is referred to as the topology. How nodes in a network are connected to each other and communicate is determined by the topology. There are three basic topologies with several typical variations‚ or combinations. A description of four topologies follows. Mesh Topology Mesh topology is the first topology discussed
