Description

Personal computer having a writing control device of data

The present invention relates to a control device provided in a personal computer. More specifically, even if a user requests a write command (delete or modify) of work data due to carelessness of the user, the user judges whether the work data created by the user The present invention relates to a personal computer equipped with a control apparatus for writing work data that protects work data created by a user by ignoring a corresponding write command request when determined to be data.

In general, a personal computer (PC) is a computer used by an individual at home or an office.

Among the devices constituting the personal computer, a 32-bit microcomputer is commercially available for a control unit (Central Processing Unit, hereinafter referred to as a CPU) that performs control and arithmetic operations, which are the most important brain parts of the personal computer. . The input device includes a keyboard, a mouse, a joystick, and the output device includes a cathode ray tube display (CRT display) device and a printer.

In addition, the memory function reads random access memory (RAM) memory, which is a main memory of a computer, which can be accessed within a certain time regardless of a location where data is stored, and a read only ROM. Only Memory). The ROM memory is typically a hard disk of a computer (including a solid state disk), and such a hard disk includes an operating system (hereinafter referred to as an OS) and other application programs managed by the OS. , Image processing programs, etc.) are stored.

In this way, if you want to perform tasks such as document and drawing creation and image editing by using the PC configured, first install the corresponding application to provide the operation to the hard disk and then execute it. In this case, if the executed application program is a document program, the document task window is activated in the monitor, which is an output device, and when the user creates a document using the input device and requests the storage of the created document, the CPU requests the document program. To be stored on the hard disk.

As such, the personal computer provides a user with various tasks required by the user, and the specific data generated (or modified) by the task is assigned by the user so that the user can later view, modify, or transmit the data. It is stored in a specific area of the hard disk, which is a folder (has a hierarchical directory structure).

However, the following problems arise when using the PC described above.

The document data created by the user is stored in the hard disk of the PC. As such, the stored document data may be modified or deleted inadvertently by the user. For example, the Windows Explorer supported by the personal computer's OS displays the stored document data by separating them into icons. As the user selects the stored document data for processing such as moving or copying the document data represented by the icon in this way, it is almost impossible to restore the deleted command if the delete command is performed due to the user's mistake. If the data is required document data, there is a problem that needs to be rewritten.

Moreover, the tasks you perform are generated by these tasks because they work with documents (word processors) and various applications such as database programs, web browser development tools, paint brushes, image editing programs, and communication programs. When arranging various created data such as hwp file, doc file, pdf file, psd file, ai file, dwg file, asx file, html file, etc., valuable work data that have been created can be deleted due to user's carelessness.

In addition, since general companies use a plurality of PCs networked in the office to improve work efficiency, multiple users can access through networking, such a problem can be amplified even more greatly. There is a need for a means for canceling the write prohibition or the write prohibition in advance at the request of the user, which includes the deletion or modification of all created work data.

The present invention is to solve the problems of the prior art, an object of the present invention is to provide a personal computer (PC) to the device for executing the write prohibition and write prohibition of the work data created by the user due to carelessness of the user The present invention provides a personal computer equipped with a control apparatus for writing work data that can safely protect valuable work data created by a user by disregarding a write command including deleting or modifying work data.

Hereinafter, with reference to the accompanying drawings for the configuration and operation of the embodiment of the present invention will be described in detail.

1 is a block diagram schematically showing a write control apparatus for working data provided in a personal computer according to the present invention, and FIG. 2 is a perspective view showing a write control switch installed in a main body of the personal computer according to the present invention.

As shown, a personal computer equipped with a write control device for working data of the present invention includes a plurality of applications for generating work data by a task after a user requests execution and an operating system for managing the plurality of applications. And a hard disk 20 storing work data generated after the work using the plurality of application programs, and a RAM memory 30 which is a main memory of a computer that can be accessed within a predetermined time regardless of the location where the data is stored. And an output device 40 including a display device and a printer, an input device 50 including a keyboard and a mouse, and a specific application program when a request for execution of the specific application is requested from the input device 50. In a personal computer comprising a CPU (60) which performs arithmetic control so that it can be used,

The plurality of applications under the control of the operating system (OS) and the CPU (60) for managing the plurality of applications and the plurality of applications to generate the job data by the task after the user's execution request to the hard disk 20 In a personal computer in which job data generated after a job is stored by using a program, the hard disk 20 includes a job data write control application program which controls to prohibit writing (deleting or modifying) of the stored job data on request. And a switching device 70 for storing the job data write control application program by an operation of the write control switch 71, wherein the CPU 60 operates from the switching device 70. When there is a request to execute the data write control application program, the job data write control application program stored in the hard disk 20. The program is executed, and if there is a request for deleting a job data thereafter, the write control application program is ignored by the executed write control application program to control the writing of the job data to be prohibited.

The write control application program is programmed so that the CPU 60 ignores the delete command of the job data when a delete command request of the job data is input during execution.

The personal computer equipped with a write control device for working data of the present invention further includes a floppy disk 10 used as an auxiliary storage medium, and is executed even when a request for deleting or modifying information stored on the diskette of the floppy disk 10 is executed. If the deletion or modification request target is job data by the write control application program being executed, the CPU 60 ignores the deletion request.

Reference numeral 10 denotes a floppy disk and 80 denotes a main power switch.

As described above, in order to protect the work data created by using various application programs mounted on a personal computer equipped with a write control apparatus of the work data of the present invention, the main power switch 80 installed on the computer main body 100 is first used. To operate the computer.

Thereafter, when the write control switch 71 installed in the computer main body 100 is operated, the switching device 70 requests execution of an application program for writing job data.

The CPU 60 executes the write control application program stored in the hard disk 20 in response to the execution request of the job data write control application program of the switching device 70. At this time, the CPU 60 connects the write control application program to the RAM memory 30 to read the write control application program, reads the write control application program, and executes the read control application program.

As such, in order to execute a task such as organizing, copying, or transferring various job data stored in a hierarchical directory structure on the hard disk while a write control application program is executed, a user may use a keyboard (or a mouse), which is an input device 50. After running Windows Explorer, select the job data to be organized, copied or transferred.

As such, when a delete command is requested by pressing a delete key by a user's carelessness while selecting specific job data, the running write control application is programmed such that the CPU 60 ignores the delete command of the job data. The CPU 60 ignores the delete command of the requested job data.

At this time, the write control application program displays a warning window on the output device indicating that the user is prohibited from deleting or modifying the work data on the output device so that the user can recognize it. If it is not, it is possible to recognize that the write control application program is currently running, thereby inducing the execution of the currently executing write control application program.

When the release of the write control application program is operated, the switching device 70 requests the release of the currently executing job data write control application program by operating the write control switch 71 installed in the computer main body 100.

The CPU 60 erases the write control application program by deleting the write control application program copied to the RAM memory 30 in response to the release request of the job data write control application program of the switching device 70.

In addition, the write control application includes an extension of the application (for example, hwp, doc, pd, psd, ai, dwg, which generates work data generated or modified by a user's work among all applications currently in use). asx, html) is recorded, and when a delete command is requested from the input device, the CPU 60 can program the extension of the requested file to be matched with the recorded extension to determine whether the job data exists. . That is, when the same extension does not exist between the matching extensions, the CPU 60 executes the requested delete instruction so that the smooth use environment of the computer can be smoothly performed.

In addition, a personal computer equipped with a write control device for working data of the present invention is provided with a floppy disk 10 used as an auxiliary storage medium, which is executed even when a request for deletion or correction of information stored on the diskette of the floppy disk 10 is executed. If the deletion or modification request target is job data by the writing control application program being executed, the CPU 60 ignores the deletion request.

As described above, the present invention includes a device capable of executing the write prohibition and the write prohibition release of the work data on the personal computer, and requests a write command including deletion or modification of the work data created by the user due to user's carelessness. Even if it is, it ignores this and it is effective to protect the valuable work data created by the user.
