Hacking code is a phrase that describes a software programmer writing software code for any purpose using any computer programming language. This is where the term hacker first came from, but is different from the negative meaning of hacker today.

Handlers are program instructions used in object oriented programming. They are embedded within objects and can perform functions when they recognize events within the programming environment.

Hard copies are any documents that have been printed on a printer. A hard copy is the physical print out on a piece paper. It can be physically viewed and stored outside of the confines of the computer monitor.

Hard disks are storage device housed in the computer that contain the computer's data. One hard disk can be divided into separate partitions. Each hard disk or hard drive is formatted and mounted after being physically attached to the computer system.

Hard drives are storage device housed in the computer that contain the computer's data. One hard drive can be divided into separate partitions. Each hard drive or hard disk is formatted and mounted after being physically attached to the computer system.

Hard returns refers to the use of the Enter key or Return key on the keyboard. This key will create a new line in a document.

Hardware is the term for all the solid physical parts of a computer system. Computer hardware includes the internal components like the motherboard, circuit boards, RAM chips, expansion cards, as well as the external user interface devices such as mouse, keyboard, cameras, speakers, etc. Hardware and software combine to make up an entire computer system.

Hardware devices are any specific pieces of hardware on a computer system. A hardware device usually refers to a peripheral device such as mouse, keyboard, cameras, speakers, but could refer to an internal device such as video cards, network cards, etc.

Hardware platforms for any computer is the equipment standards for that system. It describes the architecture of the computer hardware. Some computers have hardware that is compatible with certain standards and are listed as such. Certain hardware devices and programs created for one platform may not work with other platforms unless they are platform independent.

Help is the user information about operating systems or software applications that include such things as instructional tutorials or documentation. There are normally help menus with most GUI applications. Typing the word help or a question mark on a command line can provide access to help documentation. Using a -h, -?, or -help after a command can sometimes bring up a help menu. There are other help utilities like indexes, searches and wizards also available to the user.

Hexadecimal code is a low level computer language represented by a pair of hexadecimal symbols. These symbols are based on the number system with a base of sixteen. The numeric system called the hexadecimal system uses sixteen symbols as digits, zero through nine and the number ten through fifteen are represented by the letters A through F. Our normal numeric decimal system is based on ten numbers. The hexadecimal is used as a compromise between binary code using binary numbers and higher level programming language.

Hexadecimal system refers to the number system with a base of sixteen. It uses sixteen symbols as digits, zero through nine and the number ten through fifteen are represented by the letters A through F. Our normal numeric decimal system is based on ten numbers. The hexadecimal system is used as a compromise between reading binary numbers and converting to decimal and it still closely represents the binary numbers, but takes less space. Binary code is often represented as hexadecimal code by a pair of hexadecimal symbols.

Home page is a web site's front page that the user first sees when typing in the web site's domain name. It is usually named index.htm.

Hop in network terminology refers to data that moves between two or more networks.

Host systems are computers on the network in an OSI system that contains the server-side applications necessary for communicating through all seven layers of OSI protocols within the OSI network model. A host system allow client computers to access services through client applications.

Hostnames are the specific names of server computers on a network. Similar to the username the hostname distinguishes the identity of the computer system to the network.

Hot keys are a keystroke or set of keystrokes that are shortcuts to a command or function within a software application or operating system.

HT

HTML stands for the HyperText Markup Language. This is the first common language for creating web sites on the web. HTML is a markup language that uses the HTTP protocol for creating text based web documents. The term hypertext refers to the linking capability and the term markup refers to the tags that mark the text with HTML elements. HTML is used for creating text formatting, on-line forms, links to digital objects such as graphics, movies and sounds. HTML is a subset of SGML. The HTML standards specifications are updated through RFCs and organized by the W3C.

HTML attributes are part of the HTML tags that give properties to the HTML elements in the tag. There are also file attributes that are attributes associated with the file system.

HTML documents are the main component to a web site. They are also called web pages. Each web page is a text based file that uses languages like HTML or XML. It uses hypertext links to connect it to other web documents. An HTML document can contain formatting, hypertext links to other documents, forms for user input or digital objects such as graphics, movies and sounds. There is a set of standard specifications created for the HTML language recommended by the W3C.

HTML elements are part of the HTML tags that give properties to the text and images within the HTML document. These elements have HTML attributes that give them specific properties.

HTTP stands for Hypertext Transfer Protocol. It is the most popular protocol for delivering HTML and XML web sites over the World Wide Web. It is based on open standards. According to the W3C HTTP versions 1.0 and 1.1 are both acceptable protocols for HTML documents on the web. Web servers run the HTTP service for web hosting of web sites.

HTTP port is a Hypertext Transfer Protocol port used in TCP/IP as part of the Internet address where each port is associated with a service. Port 80 is the default HTTP port. In a web browser URL address the port used can be specified as a number after a colon at the end of the domain name. Every service on an Internet server listens on a particular service. In a web browser URL address the port used can be specified as a number after a colon at the end of the domain name. Every service on an Internet server listens on a particular HTTP port number. An HTTP port is also known as an IP port.
