이 날 발표하고 교수님께 칭찬 받았다
- very impressive
- 같은 아티클로 석사과정, 박사과정, MBA까지 여러번 수업했는데 그간 한거 통틀어서 제일 잘했다고~!!
발표하고서 그렇게 칭찬 받은 적이 없었기에, 그리고 이번에 내가 한 부분이 많았기에, 기분 정~~말 좋았던 시간!!
In computer networking, a Media Access Control address (MAC address), Ethernet Hardware Address (EHA), hardware address, adapter address or physical address is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number. <= 위키피디아 영문판
즉, 네트워크 장치가 가지고 있는 고유의 주소, 집마다 가지고 있는 집주소
참고로, 인터넷은 TCP/IP를 사용하고 IP 주소를 Mac 주소로 바꾸는 과정이 필요한데 이 과정은 ARP(Address Resolution Protocol)이라고 함
2. MAC Address 확인법
IP 확인할 때처럼 ipconfig를 입력하고 옵션으로 /all 을 넣어주면 된다.
Physical Address : 00-22-64-78-38-B5 이게 Mac Address!
16진수로 표기되는 48bit의 값
제조사가 IEEE를 통해 Mac Address를 일정 범위 만큼 받고, 네트워크 장비에 적용하였을 경우, 앞 쪽 절반 (00-22-64)는 제조자를 나타내는 OUI(Organization Unique Identifier), 나머지 절반(78-38-B5)는 제조사가 장비에 분배하는 Host Identifier
