1. What is IT infrastructure and what are its components?
2.What are the stages and technology drivers of IT infrastructure evolution?
3. What are the current trends in computer hardware platforms? Describe the evolving mobile
platform, grid computing, and cloud computing
4. What are the current trends in software platforms? Define and describe open source software
and Linux and explain their business benefits.
5.What are the challenges of managing IT infrastructure and management solutions? Name and
describe the management challenges posed by IT infrastructure
Solution
1.IT infrastructure is defined as a shared technology resources which is sum of all free and
licensed system software,third party services,owned or leased equipment that provide the
platform for the firm’s specific information system applications. IT infrastructure includes
hardware, software, and services that are shared across the entire firm.
2.The stages of IT infrastructure evolutions is began on the year 1930 and still it is continuing.
Electronic Accounting Machine-(1930-1950)->This era is began to replace Human effort from
accounting work.Machine started doing accounting and finance work effectivly and much more
errorfree than Human.
General-Purpose mainframe and minicomputer Era(1959-continuing)->This era has been started
by IBM, And it still persist in the position of supplying mainframe computer.Mainframe
computers are centralized computing with networks of terminal concentrated in the computing
department.In the mean while early models contained proprietary software and data.Mainframe
comuters able to process a wide variety of software and data ,It could able to process huge
amounts of data and transmission.
Personal Computer Era(1980 to Present)->Personal computers make a boom in both Home and
corporate sector .Personal computer makers like Microsoft and Apple take forward the evolution
by providing Desktops and Laptops which doubles the User effort.
Client/Server Era(1983 to Present)->as the desktop and laptop personal computers became more
powerful and cheaper, businesses began using them to replace mini-computers and some
mainframe computers by networking them together. Think of an octopus, with the body
representing the server and the tentacles representing the clients. At the heart of every network is
a server. It can be a mainframe, midrange, minicomputer, workstation, or a souped-up personal
computer.The client computer is the node on the network that users need to access and process
transactions and data through the network. Rather than one server trying to do it all, each server
is assigned a specific task on an application server.
Enterprise Internet computing Era(1992 to Present)->Perhaps no other era has seen the explosive
growth in functionality and popularity as this era. The problems created by proprietary, closed
systems are being solved by the standards and open-source software created in this era. The
promise of truly integrated hardware, softwar.
Information Technology IMP question and answers. The students who are enrolled for Competitive Preparations, they can go through this. This can help in your career.

6. The Need For Speed! The dominant chip architecture is multicore processors. Dual-core processors are also widely found in the TOP500 (the top 500 big computers). IBM and HP have sold the majority of the systems in the TOP500 (over 50% in the USA). The IBM BlueGene/L system claimed the Number 1 spot, which had been in first place since November 2004. Intel processors were used in a whopping 70% of the 2007 systems. AMD Opterons came in second place, while IBM POWER chips were third. Speed doubled! The 2007 winner achieved a Linpack benchmark performance of 478.2 teraFLOPS (TFLOPS), as compared to 280 TFLOPS just six months earlier, before a major upgrade. Top speed now is 596 TFLOPS In 2008, the Cell/AMD Opteron-based IBM Roadrunner at the Los Alamos National Laboratory (LANL) was announced as the fastest operational supercomputer, with a sustained processing rate of 1.026 PFLOPS. It uses 2 different architectures (hybrid system). But in June of 2010 …. 6

50. Manager’s Role :Strategy to IS Implementation Business Strategy drives architecture. Managers must understand how to plan IT to realize business goals. Logical framework is used to guide the translation from business strategy to IS design. Know the state of existing architecture and infrastructure when translating strategy into architecture and then infrastructure. A business continuity plan is an approved set of preparations and sufficient procedures for responding to a disaster event. It is becoming more important that business managers effectively translate business strategy into IT infrastructure. 50 Copyright 2006 John Wiley & Sons, Inc.

The Floppy: kilobyteAt what point do you turn over your old software for the new
Roadrunner uses Opteron chips from AMD and IBM’s Power Architecture (RISC – reduced instruction set) as opposed to CISC (complex instruction set).Intel makes Multi-core. Lots of chips that process and interact with each other on one board. Beats IBM

groupwareSoftware that integrates work on a single project by several concurrent users at separated workstations.workflowThe automatic routing of documents to the users responsible for working on them. Workflow is concerned with providing the information required to support each step of the business cycle. The documents may be physically moved over the network or maintained in a single database with the appropriate users given access to the data at the required times. Triggers can be implemented in the system to alert managers when operations are overdue.Workflow Keeps Documents MovingThe manual flow of documents in an organization is prone to errors. Documents can get lost or be constantly shuffled to the bottom of the in-basket. Automating workflow sets timers that ensure that documents move along at a prescribed pace and that the appropriate person processes them in the correct order.Workflow IntegrationIntegrating workflow into existing software applications may require extensive reprogramming, because although independent workflow software can launch a whole application, a workflow system must be able to invoke individual routines within the application. As a result, vendors of application software have teamed up with workflow vendors to provide the appropriate interfaces and/or they have developed their own workflow capability. Workflow standards developed by the Workflow Management Coalition www.wfmc.org) provide interoperability between workflow software and applications as well as between different workflow systems (see Wf-XML).Workflow Vs. WorkgroupWorkflow software is not the same as workgroup software, otherwise known as groupware. Workflow deals with the step-by-step processes, whereas workgroup systems are concerned with information sharing and threaded discussions among users.
