A wireless access point can function as which type of shared medium?
A wireless access point can function as an access point and it can also be used as a repeater....
What is wireless topology?
It's a network architecture which employs wireless devices. Compared to "classical" network topology, where the cable is network medium, in wireless networks is the air a network medium. It means, that all data travels through the air. Wireless topology can be of 2 basic categories: Ad-hoc = no central device, just a bunch of computers connected together through their wireless network adapters. Infrastructure = there is a central device called "access point" to which all client computers connect. This access point provides interconnectivity between clients and also sometimes between the wireless and wired network.
What measures the amount of time it takes a storage device to locate an item on a storage medium?
access time
What is the main function provided by Cisco WCS?
The main function served by Cisco WCS or Cisco Wireless Control System is serving as a comprehensive platform to meet the needs of small, medium and large-scale wireless LANS in local, remote, national and international locations.
What is the primary purpose of RTS and CTS?
RTS (Request to Send) and CTS (Clear to Send) are part of the wireless communication protocol used to manage access to the shared wireless medium. Their primary purpose is to prevent collisions in data transmission by allowing a device to request permission to send data (RTS) and receiving an acknowledgment from the receiving device (CTS) that indicates it is clear to proceed. This mechanism is particularly useful in environments with multiple devices, ensuring efficient and orderly communication.
Which mac sub layer are used in ieee 802.11 wireless lan?
In IEEE 802.11 wireless LANs, the Medium Access Control (MAC) sublayer consists of two main components: the MAC Control sublayer and the MAC Data sublayer. The MAC Control sublayer is responsible for managing access to the shared wireless medium and handling frame control, while the MAC Data sublayer is tasked with the encapsulation and transmission of data frames. Together, these components ensure efficient communication and coordination among devices in a wireless network.
What is the difference between a core network and an access network?
core network is for swithiching of calls,routing,authentication,providing services like sms,prepaid,rbt etc but access network is used to provide network access to end users through wireless or wired medium
What function do cell repeaters have?
Cell repeaters have functions like extension of wireless range. When two hosts are being used, they have to be connected using a MAC (Medium Access Control) and a PHY (Physical Layer) but the connection is too long and to make it easier and shorter, one have to use cell repeaters to bridge the gap.
Medium of networking?
Fibre Optics, Copper, Air (Wireless)
Which may not be a medium technology for a wireless LAN?
radio waves
What does a wireless network use as its transmission medium?
radio waves
What are the advantages of using Wireless Communications over Wired Communications?
Wireless Communications as they open a more open medium, have the following distinct advantages over wired communications- cheap installation cost, easy installation and user access, high level of mobility and rapid deployment.lity
