Computer Parts Online

In today’s age, building computers on yourself is often chosen as the safest and choicest option by a sizeable part of the market for computers. There are various advantages and disadvantages for doing so.

When personal computers first entered the mass market, building a computer was an arduous and risky task. Getting the right computer parts was also difficult and without a guarantee. Putting the whole thing together was a risk because of the newness of the product as well as the absence of expert knowledge. But over the years, the market has understood the process of computer assembly and the heavy savings involved in making your own computer (you basically save on the branded company’s professional service charge for putting the computer together for you).

Customers are able to find everything needed to build a computer on the Internet. If you want to assemble the whole system at one go, you can get a barebone computer system and keep adding on later. Using quality but cheap computer parts is the key trick behind assembling computers.

There are thousands of cheap computer parts on the web today. A quick check list of the main components you need to build your computer is –

Fundamentals of Enterprise Resource Planning ERP

Enterprise Resource Planning (ERP) plays a critical role in business, requiring people to have a general understanding of the key components of ERP to function well in any organization. Businesses have been transitioning to computer technology at an increasing rate since the advent of the desktop computer in the early 80’s. The focus of computer technology in business has always been to increase productivity through information management. Since the introduction of the Internet and advances in networking technologies and software, businesses must implement some form of computer technology to automate common tasks like word processing, accounting, and Internet access by employees, to more advanced software applications covering all or most of an organization’s business processes. These advanced software applications, generally known as ERP, capitalize on computer technology and enable businesses to have detailed perspectives into a wide range of business operations, allowing them to share information quickly between organizations, departments and personnel for better management.

ERP is a loosely used term primarily describing software but encompasses hardware and software systems used by an enterprise to gather, store, retrieve, and use information flows through an enterprise. The term ERP, therefore, can apply to a single microcomputer using an accounting package (Quick Books for example) to track sales, inventory, billing and accounting, to more complex ERP systems that automate business processes across the supply chain from manufacturing, distribution, retail, service and, ultimately, the customer, who may be either downstream or upstream in the supply chain. These functional abilities of ERP are generally grouped into software categories known as Supply Chain Management (SCM) and Customer Relationship Management (CRM) and can be implemented in small, medium, or large businesses using various hardware and software configurations. Complex ERP systems can be designed (hardware and software architecture) to service large multi-national corporations using the Internet, Intranets, and Extranets in their business operations. An Intranet functions like the Internet; however, it is limited to the organization and its users and denies access to the public. An Extranet, on the other hand, is a mechanism that allows authorized persons to access portions of an enterprise’s Intranet (over the Internet) with a username and password. For example, a manufacturer may allow dealers to access their Extranet to view product and pricing data, proprietary information limited to authorized dealers only.

ERP is an extremely complex subject best understood by looking at the major components of an ERP system including hardware, software, and primary areas of concern for business owners and managers. By looking at these major components from a conceptual viewpoint, we can side step technical jargon allowing for a greater understanding of the purpose of ERP and its importance in business and the workplace.

Hardware

The size of an organization dictates the type of hardware used in an ERP system. For small businesses, the hardware component of an ERP system could be a single microcomputer or a few microcomputers connected together over a local area network (LAN). In the case of a small LAN, one of the microcomputers would act as a server, which is simply a dedicated computer with the primary task of acting as a centralized data warehouse where data is stored. The server accepts data inputs, processes those inputs and “serves up data” to other software applications, or, provides output in various forms including screen information, print output or other types of digital output.

Typically, in larger ERP environments, an enterprise will use a dedicated server, which, in most cases, is a mini-computer. Mini-computers have greater operating and storage capacity than desktop computers and can service many users at one time. Users access the server via either dumb terminals (a monitor and keyboard) or a smart terminal (a fully functional desktop microcomputer) networked to the server via a Local Area Network (LAN). How the server and the new (or existing microcomputers, known as legacy systems) are connected lays the foundation for the hardware component of the system architecture. How these systems are connected to the server and, to each other, form the topology (or layout) of the system throughout an organization.

One of the primary concerns facing many businesses; new computer hardware acquisitions, has a twofold dimension; on one hand, it is critical to acquire state of the art computer equipment that will not become antiquated quickly by changes in technology while, on the other hand, attempting to interface older, existing systems into the ERP system. This is especially important if the existing legacy systems perform many business processes, making the transition to ERP, and systems integration, more complicated.

There are many technical issues involved with hardware configurations, requiring the expertise of Information Technology (IT) Specialists. User-operators of an ERP system rarely deal with these technical issues, have little or no input regarding system configurations and rely on technical support personnel to handle technical issues, training, and support.

In summary, the hardware component of an ERP system is comparable to the skeletal system of the human body; it is the framework, or platform, which the software “rides “on and provides the interface for users interaction.

Software

ERP software encompasses most business processes and, according to the Department Of Defense, U.S. Enterprise Solutions Competency Center:

The activities supported by ERP systems include all core functions of an enterprise, including financial management, human resources management, and operations. Increasingly, ERP vendors are offering “bolt-on” products that provide specialized functionality to augment the core, such as Advanced Planning and Scheduling (APS), and Customer Relationship Management (CRM) (2007).

ERP software design uses a “best business practices” approach that helps ensure data accuracy and integrity. For example, all accounting software design forces users to enter financial data according to the rules of generally acceptable accounting practices (GAAP) standards. This GAAP standard helps ensure that financial statements and reports reflect the true financial condition of an enterprise. Accounting software achieves this conformity by controlling the entry of financial information into the software program. Similar types of strict-standards used in ERP software conform to industry standard business practices throughout the ERP software, including bolt on products. According to author Jim Welch:

Companies can learn from lessons of past implementations. Many programs were overly focused on IT functionality at the expense of business process development. As a result, their expected benefits were compromised or delayed. Conversely, the best performers ensured that process management, governance, and other nontechnical issues were addressed properly (2007).

One of the primary considerations of ERP software is whether a business’s processes and practices will conform to ERP software (best business practices) standards without radical modification of the software. This can, and often does, mean that a business will have to change its business processes to conform to the software, rather than the reverse. This is practical for a number of reasons; first, software modifications can be cost prohibitive to smaller companies and secondly, software modifications can put data integrity at risk, jeopardizing the very purpose of ERP. Additionally, software modifications can make software upgrading, even with the same vendors and software application (ERP2.0 to ERP 2.1, for example), extremely complex and costly.

One of the key considerations in selecting an ERP software system is how well the business processes will fit into the best business practice standards of an ERP program and potential integration with present and future bolt-on programs. This is a complex issue well outside the scope of this document and requires a thorough analysis of the individual software packages on the market in conjunction with senior management working with IT consultants who represent the ERP software vendors.

In summary, the software component of an ERP system is the heart of business information and is comparable to the arterial system of the human body, data flows through it, the lifeblood of the organization.

Software Vendors

The major players in ERP software are Oracle/PeopleSoft and SAP and both companies are highly respected in the ERP industry. While there are competitors, these two companies dominate the market with nearly 20 billion in combined annual revenue, with Oracle at $10 billion and SAP at $9.7 billion. This does not mean these two software companies represent the best ERP solution for every business. Indeed, one of the most important elements of acquiring an ERP system is due diligence to find the right application software for the business, or, according to Dustin Alexander of Global Shop Solutions; “you can’t invest too much time in the evaluation process” (2007).

The selection of the software component(s) of an ERP system is one of the single most important issues facing a business considering an ERP implementation. Most businesses do not have the IT staff to oversee and manage the entire acquisition process, which requires careful management scrutiny from many different angles to safeguard the IT investment. Depending on the size and scope of the ERP acquisition, a business can expect to draw upon outside professionals to conduct a variety of analyses including feasibility, business process, and vendor/software performance. Implementing an ERP solution in an organization is a deep science requiring the best of business and IT minds, working together to help ensure the success of the project across a wide spectrum of issues. Among these issues are functionality, effectiveness, usefulness and user friendliness with an eye on acquisition costs, phased implementation, training, process transition, and ongoing development that achieves the goals and objectives of the organization.

Top Business Issues

There are many important issues facing a business considering implementing ERP and management must perform due diligence throughout the process to safeguard against system failure. Successful projects begin with a well-written plan detailing each step of the acquisition process in a way people can understand so that management can take ownership of the project and employees will use the system. Among these issues are contract negotiations covering hardware and software, software-licensing agreements, modifications, upgrades, technical support, service, training and assistance transitioning people and processes. Further, the business must establish a governance model to control all aspects of an ERP systems implementation with emphasis on business process transition that address the organizational needs and keep the business mission at the forefront.

Conclusion

Small, medium, and large businesses use computer technology to manage their businesses operations and streamline data flows for better business management. Business applications can be as simple as using Quick Books to manage inventory, billing and other financial processes, or very complex systems known as Enterprise Solutions. ERP systems can encompass departments or organizations and use a variety of hardware and software configurations to support and automate business operations. Among the more complex systems, the use of microcomputers, servers, operating systems, and application software support the Internet, Intranets, Extranets, local area networks (LANS) and wide area networks (WANS) to communicate and share data between departments and organizations.

ERP is a complex but understandable topic that plays a huge and growing role in business and government, requiring people to have a greater perspective into this technology and application in the workplace. The three major components of an ERP system are hardware, software and the people who operate it. The important thing to remember is that ERP is highly technical, and no single person has all the answers when it comes to implementing ERP systems. In order to ensure the success of ERP implementation in enterprise, many qualified business, and IT professionals must work together across a variety of disciplines to maximize the potential for a seamless transition to a digital enterprise.

10 Top Reasons Why I Have to Upgrade My Computer

The rate at which technology is improving is very fast and in the time you get comfortable with the computer hardware you have bought, several new and improved models appear in the market. While some people prefer to keep their computers state of the art, most of us have a ‘If it isn’t broken, don’t fix it’ attitude when it comes to upgrading or replacing our computers.

This is a strategy that could prove expensive in the long run. It is always better to upgrade your computer on a regular basis, especially if you have had it for over 2-3 years. Even if your computer has had a largely trouble-free existence, you really need to consider periodic upgrades and here are the reasons why you must dos so:

1. Increase in Processing Speed – This is one place where you really get to notice an improvement in performance. If you are upgrading from a Celeron 433MHz processor to a Pentium 4 1.6GHz, you would really notice the difference in performance!

2. Faster Memory Access – Improvements in CPU speed are usually accompanied by improvements in the speed at which data transfer occurs between the CPU and RAM. This is another area that provides an improvement in performance.

3. Size and Capacity improvements – Technology drives a reduction in component size coupled with an increase in storage capacity. This means that a RAM card or Hard disk of the similar size as the older ones in your computer could have double the capacity!

4. Software Compatibility – Many of the new software packages you may wish to use in order to improve your productivity or entertainment experience may not function well on you old computer. It is better to upgrade your computer to enjoy the benefits of new software fully.

5. Obsolescence of Hardware – As your hardware gets older; getting a replacement will get more difficult once manufacturers begin phasing out the production. With improvement in technology, the older hardware becomes cheaper initially and becomes expensive as supply dries up.

6. Technical Support Issues – Many manufacturers stop providing technical support for older components as they cease production. The older your computer gets, the harder it is to find help in fixing it when it malfunctions.

7. Development of New Hardware – New hardware products appear in the market frequently that revolutionize your computer experience and are based on newly developed technology. The chances of your old computer supporting new devices are very low.

8. Faster Devices – Your old computer may not be in a position to accommodate the speed at which the new devices communicate.

9. New, Fast Communication Protocols – You may not be able to implement newer or faster communication protocols in your old computer because the hardware is unable to support them.

10. Operating System and File Format – Your old hardware may not be able to run newer operating systems and some of the file formats may not be supported.
