What is WAN protocol? Explain the main difference between the BSS and ESS wireless topologies. To what kind of wireless topology do the 802.16 standards apply? List and describe the main tasks that are performed during sys Wireless access points (WAPs) use CSMA/CA. Why do WAPs need to use...
What is the main function of the CPU? How many hosts per subnet can you get from the network 172.24.0.0 255.255.255.0? What type of devices would be better served to have static IP configuration? What is the difference between computer structure and computer function?
ESS: extended service set, a group of all STAs in the same logical management domain. An ESS may contain multiple BSSs. BSS: basic service set, an area covered by an AP. Each BSS is identified by a BSSID. The simplest WLAN contains only one BSS, and all STAs are in the BSS. ...

The ___ of a communication channel or transmission medium is the difference between the highest and lowest signal frequencies that it can reliably transport. A flip flop has 5 ns delay from the time the clock edge occurs to the time the output is complimented....
Each set of wireless devices communicating directly with one another is called a basic service set (BSS). Several BSSes can be joined together to form one logical wirelesslocal area network(WLAN) segment, referred to as an extended service set (ESS). An SSID is the 1- to 32-byte name ...
(bss) basic service set. when multiple bss join, it forms one logical wlan segment known as (ess) extended service set. the ess is given 1-32 byte alphanumeric names and is called (ssid) service set identifier. characteristics of ssid the ssid is a unique identifier that helps to ...
The name of a section is not significant within the specification, however there are conventions such as .text for executable code, .data for read-write data and .bss for zero initialized data. Sections:表示一个连续的字节范围,链接器必须将其作为一个不可分割的chunk来处理。一般来说,链接器不...
What is OpenStack architecture? Explain the main difference between the BSS and ESS wireless topologies. To what kind of wireless topology do the 802.16 standards apply? What is a outer planet? What are the outer planets of the Solar System?
In computer systems, a network topology is the structure of the virtual connections of a network and it may be classified as a star, bus, ring, mesh, or point-to-point topology. Learn about the different network topologies, their descriptions, and how to determine the best topology to use...
