High Definition Multimedia Interface port





High Definition Multimedia Interface port (HDMI) is a audio/video interface for transmitting uncompressed digital data, normally used for high-end home theater systems.

Ethernet port





An Ethernet port is an opening on computer network equipment that Ethernet cables plug into. These ports are alternatively called jacks and sockets. Ethernet ports accept cables with RJ-45 connectors.

Firewire port


Firewire port is form of a serial port that make use of FireWire technology to transfer data rapidly from one electronic device to another. The FireWire port has the ability to interact with a number of different devices.

Parallel port





A parallel port is a type of interface which connects externel device such as printer. It is parallel communication physical interface.

Serial port





Serial port can be used in serial communication, in which only 1 bit is transmitted at a time. A serial port is a general-purpose interface, it can be used in almost any type of device.

Universal Serial Bus port (USB)





A USB port is a standard cable connection interface on personal computers and consumer electronics. USB ports allow stand-alone electronic devices to be connected via cables to a computer (or to each other). USB only has limited GB to save your own data, and it is small so you can bring it everywhere.

Plug and Play





Plug and Play (PnP) technology provides a combination of software and hardware support that enables the Windows operating system to detect and configure hardware with little or no user involvement. Plug and Play makes it easier to add and configure hardware on a computer, it supports wide range of devices.

Network Interface Card





A network interface card (NIC) is a computer circuit board or card that is installed in a computer so that it can be connected to a network. A network card commonly found in most desktop computers today that do not already have an integrated network on their motherboard.

Sound Card





A sound card also known as an audio card. It is an internal computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs. It also also applied to external audio interfaces that use software to generate sound. Typical uses of sound cards include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education and entertainment (games) and video projection.

Graphic Card

Graphic card is a piece of hardware installed in a computer that is responsible for rendering the image on the computer’s monitor or display screen. The first consideration when buying a graphics card is to be sure it is capable of displaying the best resolution the monitor can support.

Flash Memory





Flash memory (Flash RAM) offers a combination of the features of ROM and RAM. Flash memory is non-volatile, meaning no power is needed to maintain the information stored in the chip. Like RAM, it can be updated to store new information. Like ROM, it doesn't lose that information when power to the system is switched off. Flash memory used in wide range of application.

ROM


ROM stands for Read Only Memory. Read Only means that the CPU can read or retrieve, data and programs written on the ROM chip. The computer can't write or change the information or instruction in ROM. ROM retains its contents even when the computer is turned off. ROM is referred to as being nonvolatile, whereas RAM is volatile.

Cache


Cache (pronounced as cash) memory improves processing by acting as a temporary high-speed holding area between the memory and the CPU. If requested data is contained in a cache, this request can be served by reading the cache, which is faster.

RAM


RAM stands for Random Access Memory. It holds the program (sequence of instuctions) and data that the CPU is presently processing. RAM is much faster to read from and write to than the other kinds of storage in a computer, the hard disk, floppy disk, and CD-ROM. When you turn on your computer, your operating system and other files will automatically load into RAM again, normally from your hard disk. It is wiser to save your document every few minutes.

Web Authoring


Web authoring is to design and create a Web site, from writing the site's underlying code to writing the text to managing the site's upkeep. Web authoring systemcombines web file management and easy-to-use WYSIWYG web page editing.

Vector Image


In physics, a vector is a representation of both a quantity and a direction at the same time. In vector images, the file that results from a graphic artist's work is created and saved as a sequence of vector statements. instead of containing a bit in the file for each bit of a line drawing, a vector graphic file describes a series of points to be connected. One result is a much smaller file.

Multimedia


Multimedia is media and content that uses a combination of different content forms. The term can be used as a noun (a medium with multiple content forms) or as an adjective describing a medium as having multiple content forms.

Image Editor


Image editor is a program that provided variety of features from editing bit-mapped images. The difference between image editors and paint programs is not always clear-cut, but in general image editors are specialized for modifying bit-mapped images, such as scanned photographs, whereas paint programs are specialized for creating images.

HTML Editor


HTML editor is a application software for creating web pages. The HTML markup of web pages can be written with any text editor, it offers convenience and added functionally. HTML software is easy to use since it has a feature that is known as WYSIWYG. When you design web pages you want to use editor features that are simple to understand.

Desktop Publishing Program


Desktop Publishing Program is a tool for graphic designers and non-designers to create visual communications for professional or desktop printing as well as for online or on-screen electronic publishing. It also resulted in a wider range of low-cost, easy-to-use software that didn't require traditional design and prepress skills to understand and use.

Bitmap Image


Bitmap is a type of memory organization or image format that used to store digital images. Bitmap comes from map of bits, alont with pixmap. It commonly refer to similar concept of pixels. bitmap implies one bit per pixel, while pixmap is used for images with multiple bits per pixel.

Radio Editing Software


Radio editing software can help preparing and editing music for broadcast. This software also for cross fading, mixing or other DJ applications. Most products can perform format conversions, so you can take a clip from the Internet or an MP3 file and convert it to the format your station uses for broadcasting.

Utility Suites


Utility suites is a kind of system sofware to help analyze, configure, optimize and maintain the computer. It allows users to do things like creating text documents, playing games, listening to music or surfing the web. Utility suites usually focus on how the computer infrastruture operates. Most utilities perform a single task or a small range of tasks. Some utilities combined several features in one piece of sofware.

DBMS


DBMS is the database management system. It is a computer software which designed of managing databases that is installed on a system hard drive or network. It is possible to designate one or more database administrators who may control each function, as well as provide other users with various levels of administration rights. DBMS can be a way for people to communicate with each other.

Spreadsheet


A spreadsheet is an application that simulate a paper, accounting worksheet. Spreadsheet normally is used for financial information as they can recalculate the whole sheet automatically to a single cell. Most spreadsheet application can link one spreadsheet to another. A change made in one spreadsheet automatically affects other spreadsheets.

Word Processor


Word processor is a software that people use to create, edit, and print documents. The advantage of this software is you can make changes of the document without retyping the whole. It also providing some forms of what-you-see-is what-you-get editing. Microsoft is the most common word processing software.

Graphical User Interface


Graphical user interface makes the program easier to use. Well-designed graphical use interfaces can free users from learning complex command languages. It is a computer program that enables communicating with a computer throught the use of symbols, visual metaphors, and pointing devices. It allows you let you interact by using a mouse rather than by having to type in keyboard commands. A GUI sometimes uses one or more metaphors for objects familiar in real life.
