IT Infrastucture: Hardware and Software

4.1 IT infrastructure: Computer Hardware

Business require a wide variety of computing equitment,n software, communications capabilities simply to operate and solve basic business problems.Each computer will require and operating system and a wide range of application software capable of dealing with spreadsheet, documents, and data file.

INFRASTRUCTURE COMPONENTS

Computer Hardware

Consist of tecnologi computer processing, data storage, input and output. This components includes large mainfraims, servers, desktop, laptop computers, and mobile devices for accesing corporate data and the internet.

Computer Software

Includes both system software and application sofwarethat applies the computer to a specific task and for end user.

Data Management Technology

Organize, manages, and processes business data concerned with inventory.

Networking and Telecomunnication Technology

Provide data, voice, and video connec tive internal networks, services from telecomunnications/telephone

Technology Services

To train employee how to use these technologies for their work

TYPES OF COMPUTERS

Perrsonal Computer (PC)

If we work alone or with a few other people in small business so we use laptop or desktop.

Wokstation

Powerful grapichs or computational capabilities

Mainframe

Is a large capacitiy, high performance computer that can process large amount of data very rapidly

Supercomputer

Computer thatis used for task requiring extremely rapidly and complex calculation with thousand of variable millions of measurements, thousandof equations.

Grid Computing

Involves conneting geographically remote computer into a single networks to create a “virtual supercomputer” by combining the computational [power of all computer on the grid.

Computer Networks and Clien/Server Computing

Distributed processing is the use of multiple computers link by a communications networks for processing.

STORAGE, INPUT, AND OUTPUT TECHNOLOGY

A. Secondary Storage Technology

1. Magnetic disks

2. Optical Discs

3. Magnetic Tape

4. Storage Networking

B. Input And Output Devices

CONTEMPORARY HARDWARE TRENDS

The Emerging Mobile Digital Platform

Communications devices such as cell phone s, and smartphone such as the iPhone and Blackberry, have taken many handled computers, including transmissions of data , surfing the web,etc.

Nanotechnology

Uses individual atoms and molecules to create computer chips and other devices that are thousands of times smaller than current technologies permit.

Cloud Computing

Model computing in which firms and indivuals obtain computing resourcs and software applications over the internet. Cloud Computing consists of s, 3 types of styles: Cloud infrastructure as a service, Cloud Platform as a service, Cloud softwatre as a service.

Autonomic Computing

Is an industry wide effort to develop system that can configure themselves, optimize and tune themselves, etc.

Virtualization and Multicore Procesor

Presents a set of computing resources so that they can call all be accesed in way that are not restricted

4.2 IT Infrasrtucture: Computer Software

OPERATING SYSTEM SOFTWARE

The system software that manages and controls the computers activities is call Operating System.Software consists of computer language translation programs that convert programming

APPLICATIONS SOFTWARE AND DESKTOP PRODUCTIVITY TOOLS

1. Application programming Language for Business

2. Fourth- Generation Languages

3. Software Packages and Dekstop productivity Tools

SOFTWARE FOR THE WEB: JAVA, AJAX, AND HTML

Java is operating sytem independent, processor independent, object oriented programming language that has become a leading interactive programming environment for the web.

Ajax us another web development tective web creating interativ on the web technique wb application that prevent all of in this inconvience.

HTML is a page description a language for specipying how graphics, video, text and sound are placed on a web page.

WEB SERVICES

Is refer to a set of loosely coupled software components that exchanges informations with each other

SOFTWARE TRENDS

Open Source Sofware is developed by a community of programmers around the world, who make their program avaibles to user under one several different licensing schemes.

Cloud- Basd Software Tools and Services Such as Microsoft Word or Adobe.1) Mashups is the resulting software application and Widgets are small software programs that can be added to web pages or place on the desktop to provide additional functionally.

4.3 Managing Hardware and Software Technology

CAPACITY PLANNING AND SCALABILITY

Capacity Planning is the processof predicting when a computer hardware system becomes saturated and Scalability refers the ability of a computer, product, or system to expand to serve a large number of users without breaking down.

TOTAL COST OF OWNERSHIP (TCO) OF TECHNOLOGY ASSETS

TCO model can be used to analyze these direct and indirect costs to help determine the actual cost of owning the specific technology.

USING TECHNOLOGY SERVICE PROVIDERS

Outsourcing The maintenance of their IT infrastructure and development of new systems to external vendors.

Using Cloud Services , firms now have the option of maintaining their own IT infrasturture or using cloud based hardware and software services.

Managing Mobile Platforms, a large firm have many thousand of wireless devices to configure and monitor , similar to a desktop environment.

MANAGING SOFTWARE LOCALIZATION FOR GLOBAL BUSINESS

If you are operating a global company, all of management issues we have just described will be affected by the need to create systeme that can be realistically used by multiple business units different countries.
