What Bridges filter network frames based on?
physical address
What does the format for Ethernet frames specify?
destination (physical/hardware address) Source (physical/hardware address) Start flag (start of message indicator) Recipient sender encapsulated data end of frame
Does an unmanaged switch have its own MAC address?
yes i think, because the MAC address is the physical address which is assigned by the vendor of the Ethernet card. ** Improved Answer ** No, Unmanaged switches do not have a MAC address. All they do is filter, forward or flood frames.
How can you build a virtual website for a website?
Use of iframes or frames
What is the purpose of paging the page table?
For get the attention of people in an emergency quickly.
What layer of the ois model adds source and destination MAC address to frames?
in the osi model data link layer is adds source & destination mac address to frames
Consider a logical address space with 4 pages of 1024 bytes per pageeach mapped onto a physical memory of 64 frames. how many bits are there in logical address?
4 pages -> 2^2 bits 1024 bytes -> 2^10 bits 64 frames -> 2^6 bits Therefore: Logical memory = 2+10=12 bits Physical memory = 10 +6 =16 bits
What is a logically defined device that operates at the Data Link layer to pass frames between nodes?
virtual switch
The address of the beginning of a page frame is found by multiplying the page frame number by the number of frames?
The address of the beginning of a page frame is found by multiplying the page frame number by the number of frames.
Which osi model layer generates and detects voltage so as transmit and receive signals carrying data?
The physical layer of the OSI model is responsible for encoding frames in to the electronic/RF/optical signals of the physical medium and for reading the media and translating back in to usable frames.
Consider a logical address space of eight pages of 1024words each mapped onto a physical memory of 32 frames how many bits are there in the logical address?
As was given for a 4 Page, 1024 words & 64 frames (shown below) 4 pages -> 2^2 bits 1024 bytes -> 2^10 bits 64 frames -> 2^6 bits Therefore: Logical memory = 2+10=12 bits Physical memory = 10 +6 =16 bits The answer for this problem is 13. 8 pages -> 2^3 bits 1024 bytes -> 2^10 bits 32 frames -> 2^5 bits Therefore: Logical memory = 3+10=13 bits (Page + Word) Physical memory = 10 + 5 =15 bits (Word + Frame)
What addressing information is recorded by a switch to build its MAC address table?
the source Layer 2 address of incoming frames
