How many bits are in logical addresss If a logical address space of eight pages of 1024 words each mapped onto a physical memory of 32 frames?
a.
Logical address will have
3 bits to specify the page number (for 8 pages) .
10 bits to specify the offset into each page (210 =1024 words) = 13 bits.
b.
For (25) 11 32 frames of 1024 words each (Page size = Frame size)
We have 5 + 10 = 15 bits.
What else can I help you with?
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 Bridges filter network frames based on?
physical address
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)
Consider a LA space of 8 pages of 1024 words mapped into memory of 32 frames?
In a logical address space (LA) of 8 pages with 1024 words each, the total logical address space is 8,192 words. If this is mapped into a memory of 32 frames, each frame can hold 256 words (since 8,192 words / 32 frames = 256 words per frame). This means not all frames will be utilized for the given pages, as only 8 pages are needed. Consequently, there are additional frames available in memory that can accommodate future pages or other processes.
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.
What is paging and how is it done?
Paging is a memory management scheme in which physical memory is divided into fixed-size blocks called pages, and logical memory is divided into blocks of the same size called frames. The operating system uses a page table to map logical addresses to physical addresses during memory access. When a process requests data that is not in physical memory, a page fault occurs, leading to the system retrieving the required page from secondary storage into physical memory.
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
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.
What addressing information is recorded by a switch to build its MAC address table?
the source Layer 2 address of incoming frames
What device is used to move frames between a source and a destination on a MAC address?
switch
