4. Wireless Frequency Channel
  • Frequency Channel adalah pembagian frekuensi dalam suatu band dimana Access Point beroperasi.
  • Range Frequency Channel untuk masing-masing band : 2,4GHz = 2412 s/d 2499 MHz
frekuensi 2.4 GHz (2400MHz) merupakan sinyal yang bisa ditemukan pada hampir semua perangkat nirkabel disekitar, seperti remote TV dan WiFi router.

  Configuring a DHCP Server and Connecting to the Internet   What is DHCP? DHCP (Dynamic Host Configuration Protocol) is a protocol used to facilitate the automatic deployment of IP (Internet Protocol) addresses to other devices. This DHCP configuration does not have to be manually implemented on each computer in order to get a different IP address. This will certainly be troublesome and time-consuming. IP Address or IP address itself is a row of numbers on a device that allows our device to connect to the internet, so that we can access web pages, emails, etc. Well, by using dhcp this IP address can be shared to many devices at one time automatically.

  SUBNETTING CONCEPT Subnetting is a material that comes out a lot in the CCNA exam with a variety of questions. It is also a scourge for students or instructors who are completing the CCNA 1 curriculum for the CNAP (Cisco Networking Academy Program) program. To explain about subnetting, I usually use some illustrations and analogies that we are familiar with around us. I wrote this article intentionally for colleagues who are studying networking, who are preparing to take the CCNA exam, and who are taking CCNA 1 training. Actually what is subnetting and why should it be done? this question can be answered with the analogy of a road.
