연결테스트를 위해 핑을 날리는데 언제 연결에 장애가 생겼는지 확인하기 어렵다. 인터넷 연결테스트를 위해 구글에 핑을 날려보자 아래와 같이 시간이 표시되지않는다 연결의 노이스나 일시적장애를 확인하려면 시간대를 아는것이 중요하다. 아래와 같이 bat 파일을 만들어서 실해하면 시간도 나오게 할 수 있다 ping.bat 파일을 만들어 다음과 같이 넣어보자 (create ping.bat file then add scripts below:) @echo off     ping -t 8.8.8.8|find /v ""|cmd /q /v:on /c "for /l %%a in (0) do (set "data="&set /p "data="&if defined data echo(!time! !data!)" 어렵다면 pingwiz.exe 를 사용해보자 pingwiz.exe 8.8.8.8 /t 로 간단히 시간을 남길 수 있다 도움이되었다면 좋아요 부탁한다^^

Ransomware is embarrassing when pops up with asking money There are some solutions for this kind:  1. To break the encryption of the ransomware, it is almost impossible because normally they build it one way, so after money submitted, they would not give you the key, because the key might not exist from the beginning. If they built the ransomeware upon opensource then there might be solution in public as well. If you have lots of resources and computing power, you could try bruteforce for cracking the encryption, but not recommended 2. The most easy solution is to make a backup such as windows backup may help you to restore files and folders encrypted by ransomware, so a nice backup tool and plan should be considered.  (Make a backup upon that a user account does not have a right to edit such as password lock) Such as googledrive leaves a change history, so right before the recent change made in the change history you can use to restore when ransomeware encryp...

As I had a job interview position called 'data admin', I reviewed what I had studied from Univ. Entity Relationship Modelling : is a set of diagrammatic standards for depicting both the logical and physical structure of a database system P.Chen 1976 first proposed E-R models E-R Modelling symbols : Entities, Relationships, Attributes Entities :an entity is a thing, which is recognisable as being capabl of an independent existence, and may be uniquely identified, this definition allows for both physical objects(person, car, house) and events (a meetings, loans). - the names of entities must be in the singular as it refers to a single instance (in relationship terms) Relationships : a specific line between two entities and indicates that the primary key of one entity is a foreign key in the other One to One : signifies that for each instance of entity A there is one related instance of entity B. it is not often used or seen in full-scale relationship databases...

As the assumption that there is not any software dedicated to maintaining the network and its operating system fully, WSBS provides a unified administrative interface designed to manage your server to meet the business requirements. A server is a device that provides services such as printer server, web server. These services should meet core business needs, including security (integrity, availability, confidentiality); email and collaboration; an internet connection; sharing data; faxing. A client is a device that avails itself of a server's services. Normally, they are perfectly capable computers on their own. The roles of network operating systems are to manage: Remote file system Running of shared applications input and output to shared network devices CPU scheduling of networked processes Server needs to be high powered, robust operating system, reliable hardware, do not want to have to reboot their system, and varying security needs including certain level of da...
