IT standards are official, management-approved statements that define the technologies, protocols, suppliers, and methods that are used by an IT organization. Standards help to drive consistency into the IT organization, which will make the organization more cost-efficient and cost-effective. An IT organization will have different types of standards: Technology standards These standards specify what software and hardware technologies are used by the IT organization. Examples include operating system, database management system, application server, storage systems, backup media, and so on. Protocol standards These standards specify the protocols that are used by the organization. For instance, an IT organization may opt to use TCP/IP v6 for its internal networks, GRP routing protocols, FTPS for file transfer, SSH for device management, and so forth. Supplier standards This defines which suppliers and vendors are used for various types of supplies and services. Using established suppliers can help the IT organization through specially negotiated discounts and other arrangements. Methodology standards This refers to practices used in various processes including software development, system administration, network engineering, and end-user support. Configuration standards This refers to specific detailed configurations that are to be applied to servers, database management systems, end-user workstations, network devices, and so on. This enables users, developers, and technical administrative personnel to be more comfortable with IT systems, because the systems will be consistent with each other. This helps to reduce unscheduled downtime and to improve quality. Architecture standards This refers to technology architecture at the database, system, or network level. An organization may develop reference architectures for use in various standard settings. For instance, a large retail organization may develop specific network diagrams to be used in every retail location, down to the colors of wires to use and how equipment is situated on racks or shelves.

Although implicit type inference is adequate for most invocations of a generic method, it is possible to explicitly specify the type argument. To do so, specify the type argument after the method name when calling the method. For example, here CopyInsert( ) is explicitly passed type string:

public virtual void CopyTo(Array ar)

the Find And Replace dialog features several active buttons: Find Previous, Find Next, Find All, Replace, and Replace All. Clicking Find Previous or Find Next enables you to navigate backward or forward through the search. Clicking Find All selects all the relevant objects in the document without performing the replacement operation. Clicking Replace or Replace All replaces the selected objects with the specified replacement properties or simply replaces all relevant objects in the document with the replacement properties without any further prompting. Additionally, you can find and replace text. However, this wizard is for finding and replacing the content of text, what the audience reads. It does not automatically change a font or color. If you need to find and replace a font selection, conduct a regular Replace (object), and then choose Replace Text Properties, as shown in Figure 12-9.
