• CD-ROM: It is a compact disc that uses laser light to store and read large amounts of information in digital format. 

 

• CD-RW: It is a digital format optical disc used to store any type of information. This type of CD can be recorded multiple times, as it allows stored data to be deleted.

• Hard disk: It is the data storage device employing a magnetic recording system for storing digital files.

 

• DRAM: It is used as working memory computer for the operating system, programs and most of the software. In the DRAM all instructions running the central processing unit (CPU) and other computer units are loaded.

 

 

• Firewall: It is a part of a system or network that is designed to block unauthorized access while permitting authorized communications.

 

• Firmware: is a computer program that establishes the lowest level logic that controls the electronic circuits of a device of any kind. Firmware is software that manages the hardware physically. 

 

• Gif: It is a graphical format widely used in the World Wide Web, both images and for animations.

 

• Gigabyte: is a storage unit whose symbol is GB, equivalent to 1,000,000,000 billion bytes. 

 

• Hacker: is any individual who is dedicated to enthusiastically program on a computer by encrypting passwords or codes for either common or just for activity. 

 

 

• Hardware: It refers to all physical parts of a computer system; its components are: electrical, electronic, electromechanical and mechanical. Are cables, cabinets or boxes, peripherals of all kinds and any other physical element.

 

 

• HTML:  markup language for developing web pages.

• HTTP: (Hypertext Transfer Protocol) is a communication protocol that allows the transfer of information on the World Wide Web.

 

 

• Internet: is a decentralized set of communications networks interconnected using family TCP / IP protocols, which ensures that the heterogeneous physical networks that comprise a unique global logical network.

 

 

• Intranet: is a computer network that uses Internet Protocol technology to share information, operating systems, or computing services within an organization.

 

 

• Java: is a general programming language, concurrent purpose, object-oriented which was specifically designed to have as few implementation dependencies as possible. His intention is to allow application developers to write the program once and run on any device. 

 

 

• JPEG: It is a graphical format widely used in the World Wide Web, both images and for animations. 

• Kernel: it is software that is an essential part of the operating system, and is defined as the part that runs in privileged mode. It is the main responsible for providing various programs secure access to computer hardware or basic form, is responsible for managing resources, through system call services.

 

 

• Optical pencil: It is a computer input device, as a photosensitive wand, which can be used to target objects displayed on a CRT television or monitor in a similar fashion to a touch screen but with higher positional accuracy.

 

 

• LCD: It is a thin, flat screen formed by a number of pixels color or monochrome placed in front of a light source or reflector.
