PPP Definition Stands for “Point-to-Point Protocol.” PPP is a protocol that enables communication and data transfer between two points or “nodes.” For many years, PPP was the standard way to establish a dial-up connection to an ISPs. As dial-up modems were superseded by broadband devices, PPP connections became increasing. However, PPP lives on in “PPP over Ethernet” (PPPoE), which is a common way to ..

PPTP Definition Stands for “Point-to-Point Tunneling Protocol.” PPTP is a networking standard for connecting to virtual private networks, or VPNs. VPNs are secure networks that can be accessed over the Internet, allowing users to access a network from a remote location. This is useful for people who need to connect to an office network from home ..
Freeware Definition Freeware is software that is free to use. Unlike commercial software, it does not require any payment or licensing fee. It is similar to shareware, but will not eventually ask you for payment to continue using the software. You can legally download and use freeware for as long as you want without having to pay for it. Many types ..
Shareware Definition Shareware is software that you can use on a trial basis before paying for it. Unlike freeware, shareware often has limited functionality or may only be used for a limited time before requiring payment and registration. Once you pay for a shareware program, the program is fully functional and the time limit is removed. In the ..
Gnutella Definition Gnutella is a file sharing network that allows users to send and receive files over the Internet. The first part of its name comes from the GNU General Public License, which originally allowed the source of the program to be made available to the public. The second part of the name comes from ..
Input Definition Whenever you enter data into your computer, it is referred to as input. This can be text typed in a word processing document, keywords entered in a search engine’s search box, or data entered into a spreadsheet.

Java Definition Java is a high-level programming language developed by Sun Microsystems. It was originally designed for developing programs for set-top boxes and handheld devices, but later became a popular choice for creating web applications. The Java syntax is similar to C++, but is strictly an object-oriented programming language. For example, most Java programs contain classes, which are used to define objects, and methods, ..
Compiler Definition A compiler is a software program that compiles program source code files into an executable program. It is included as part of the integrated development environment IDE with most programming software packages. The compiler takes source code files that are written in a high-level language, such as C, BASIC, or Java, and compiles the code into a low-level language, such as machine ..
C/C++ Definition C is a high-level programming language that was developed in the mid-1970s. It was originally used for writing Unix programs, but is now used to write applications for nearly every available platform. Compared to most previous languages, C is easier to read, more flexible (can be used for a wide variety of purposes), ..
Assembly Language Definition An assembly language is a low-level programming language designed for a specific type of processor. It may be produced by compiling source code from a high-level programming language (such as C/C++) but can also be written from scratch. Assembly code can be converted to machine code using an assembler. Since most compilers convert source code directly to machine code, software developers often create programs without ..
