| What is "Console"? |
|
A console is consist of an input device and an output device. For example, a combination of display and keyboard is a console. A console is used to put commands to a computer and to moniter its status. If the operater inputs an command by the keyboard, the display shows what he/she input, the result after the operation, and other information. Thus, a console is an interface between human and computer. Revised definition: A console is a combination of an input device and an output device. For example, a pair of mouse and display is a console. A console is used to communicate information between human and computer, and enables us to use computer easily. For example, Windows is a typical console software. We can put commands by a mouse and Windows shows us the result graphically on the display. |

| What is "Source code"? |
|
A source code is a list of procedure which programmers write to figure out their particular orders. Programmers write a source code according to a programming language. Some languages have the same rules with English, Japanese, or other spoken languages. Thus, source codes are so easy for programmers to understand. However, computers cannot understand the codes directly. Therefore, the codes are translated into a machine language by a program called Compiler or Interpreter. That's why this is called SOURCE code. |

| What is "Software licensing fee"? |
|
Softwares are licensed rather than sold. If a software company sell its product, according to the law, that mean its right of ownership moves to the buyer. And then, the buyer is allowed to do whatever he/she wants with it. For example, the buyer can copy it by CD-R, resell it in a lower price, and get a great profit. This must be a disadvantage for software companies. Therefore, they don't sell their products and do sell the right to use them. The money which the company cost to the buyer is called Software licensing fee. Some companies require the fee based on the number of computers on which the licensed software can run, or the number of users who can use it. Revised definition: Software licensing fee is money paid for software products. A software is licensed rather than sold. According to the law, to sell software products means to allow the buyer to do anything they want to do by them. For example, the buyer would be allowed to resell it by CD-R provided the software company sold it; thus, software companies avoid to sell their products. They just sell the right to use the product. The buyers have to pay money for them as software licensing fee. |

| What is "Reverse engineering"? |
|
Reverse engineering is the process of analyzing a final product, that is both hardware and software, to reveal its concrete structure and design. Several companies have produced compatible products of other company's one through reverse engineering. However, nearly all products are protected by copyright, patent, and other laws; therefore the companies have to be careful so as not to violate these laws. And also, reverse engineering is effective to examine if the product still has errors, security holes, and other problems. However, malicious hackers can take advantage of reverse engineering. For example, they can examine their targets through reverse engineering and break into the system when they find a security hole in it. There has been no definite rules for reverse engineering yet. Revised definition: Reverse engineering is the process of analyzing a final product, that is both hardware and software, to reveal its concrete structure and design. Several companies have produced compatible products of another company's products through reverse engineering. For example, EPSON produced an Intel-compatible CPU through reverse engineering. Reverse engineering is also effective to examine if the product still has errors, security holes, and other problems. However, malicious hackers can take advantage of reverse engineering. For example, they can examine their targets through reverse engineering and break into the system when they find a security hole in it. There has been no definite rules for reverse engineering yet. |
