How many address bits are required to address a 4096 bytes of memory?
A 1 byte wide static memory could address 4096 bytes. A 64-bit (8 byte) wide memory could address 32768 bytes.
How many address lines a memory chip of 128k capacity will have?
so now 11 address lines can access 2k memory.
How are address bits calculated?
Step 1: calculate the length of the address in bits (n bits) Step 2: calculate the number of memory locations 2^n(bits) Step 3: take the number of memory locations and multiply it by the Byte size of the memory cells.
What is a 32-bit address?
A 32-bit address is the address of a single byte. Thirty-two wires of the bus contain an address (there are many more bus wires for timing and control). Sometimes people talk about addresses like 0x2000, which looks like a pattern of just 16 bits.
How many address bits are required for a 512 * 4 memory?
32
How many address bits are required for a 2048 bit memory?

How many bits are required for physical address for 128 kB?
Consider an 128 kB (total data size), four-way set-associative cache with 16 B blocks and LRU block replacement. The cache is physically tagged and indexed. Physical memory is 32MB, byte-addressable, and words are 4 bytes each. Virtual addresses are 32 bits, and pages are 16kB.
How many bits are in a physical address?
44 bits
How is virtual memory page size calculated?
Page Table Size = number of page entries in page table X size of one page entry. Let’s consider an example, Virtual Address Space = 2 GB = 2 X 2 ^ 30 Bytes. Page Size = 2 KB = 2 X 2 ^ 10 Bytes.
How does a logical address space is represented?
The logical address is virtual address as it does not exist physically, therefore, it is also known as Virtual Address. This address is used as a reference to access the physical memory location by CPU. The term Logical Address Space is used for the set of all logical addresses generated by a program’s perspective.
What is the effective address?
The effective address is the location of an operand of the instruction, since the operand is the data to be accessed. Immediate instructions use their operand to hold the data needed to complete the instruction.
Is logical address same as IP address?
IP Address works at the network layer of OSI model (actually the IP layer of TCP/IP model). This is a logical address (and not the embedded hardware address) which is assigned by the Network administrator or Internet service provider. Hence IP address may change each time you connect with the Internet.
What is difference between logical and physical address space?
The logical address is used like a reference, to access the physical address. The fundamental difference between logical and physical address is that logical address is generated by CPU during a program execution whereas, the physical address refers to a location in the memory unit.
Is MAC address physical or logical?
MAC Address is a physical address. IP Address is a logical address.
Why do we need logical address?
The need of logical address is to securely manage our physical memory. The binding of instruction and data of a process to memory is done at compile time, load time or at execution time. Logical address comes into picture, only if the process moved during its execution time from one memory segment to another.
