The SFP is the abbreviation for the small FORM pluggable and can be easily understood as an upgraded version of the Gbic. The SFP module is half the size of the Gbic module, and can be configured with more than one port number on the same panel. The other features of the SFP module are basic and gbic consistent. Some switch vendors call the SFP module a miniaturi

Optical fiber jumper (also known as optical fiber connector) is a Connector Plug installed on both ends of the optical fiber, used to achieve optical link activity connection; one end is equipped with a plug is called pigtails.
Optical fiber jumper (also known as optical fiber connector), that is, the optical fiber connectors connected to optical modules, also have many types, and they cannot be used with each other. The SFP module (SFP (Small Form-fa
There are two types of Java virtual machines that can be handled, one is the original type (Primitive Types) and one is the reference type (Reference Types).Correspondingly, there are two types of values that have primitive values (Primitive values) and reference values (Reference values) that can be used for variable
Basic conceptsValue type:A value type instance is typically assigned on the thread's stack (stack) and does not contain any pointers to the execution of the instance data because the variable itself contains its data instance. Its definition in MSDN is that value types directly contain their data, and instances of value types are either on the stack or inline in the structure.Value

See the big God on the Internet a blog post on whether the Java language has a value type, which mentions that "Java has only reference types (reference type), but according to Java's official documentation, Java also has the difference between a value type and a reference type." Primitive types such as Int,boolean are value types. "Original address: http://yinwa

Four basic data types in javascript: numeric values (integers and real numbers), string literals (characters or values enclosed by "" or "), Boolean (make True or false), and null values. The data in the basic type of JavaScript can be constants or variables. Because JavaScript takes the form of a weak type, a variable or constant of a data does not have to be declared first, but rather the type of its data when used or assigned. Of course, you can de
