Enterprise computing is the underlying architecture that allows the underlying information to flow.
In an enterprise, users typically fall into one of four categories; Executive management, middle management, operational management and nonmanagement employees.
For example - Nonmanagement Employees - Need information in order to perform their job.
As you go up the lader operational management make day-2-day decisions. They normally require short-term decision information material.
Execs make decisions to ensure long term growth. They are very strategic decisions made with long-term goals.
Virtualization and Cloud Computing
Virtualization is the practice of sharing or pooling computing resources. There are two categories of Virtualization:
- Server - Provides the capability to divide a physical server logically into many virtual servers.
- Storage - Provide the capability to increase and create single logical storage devices from many physical storage devices.
Cloud Computing is an internet service that provides computing needs to computer users.
Grid Computing combines many services or personal computer to act as one large combined computer.
Key Terms in developing an enterprise network includes; Scalability and Interoperability.
- Scalability is the measure of how well the hardware or computer information system can grow to increasing performance demands.
- Interoperability is the ability for an information system to share information to other information systems within an enterprise.
Launched in 1989, the WWW was not originally designed for integrating multimedia. It was designed as a method of delivering simple text documents formatted in HTML.
The first browser was the Mesh (Berners Lee 1989)
Mosaic was introduced in 1993 (inline images and ease of use)
Non Web browsers differ in features, performance and cost.
Site Planning and Design
Web site design does not begin with making a Web page. A logical procedure should be followed to provide a blueprint for the effetive design and layout of individual pages and links.
The design depends on the purpose and target audience of the Web site.
A website should attract visitors, maintain interest, satisfy the users needs, ensure the site is bookmarked for future visits.
Site Planning and Design
Types of Web sites:
Instructional (educational)
Informational
Promotional (advertisement)
Entertainment
Social
Factors to consider when planning a Website:
- Purpose of the site. Target Audience, the User's browsers.
Site Purpose
The purpose of the site should be clearly defined.
Ensures the the design plan works towards satisfying the purpose; not the creative needs of the designer.
Purposeful design is the key trick to website design.
Target Audience - Requirements and needs are paramount in effective web design. Clearly define who will use your web site and what needs they have. Identify characteristics and demographics such as; gender, age, socio-economic background, education level, computer literacy level, etc.
Identify characteristics and demographics such as: gender, age, socio-economic background, education level, computer literacy level, etc.
A user must always know what page they are on at any one point in time in your website.
There are four types of navigations structures: linear structure - Forward and Backwards (One page at a time), hierachical structure, non-linear structure, composite structure / hybrid (organised as a mixture of linear and hierachical structures).
