If a particular computer has 8 byte addressability and a 4 bit address space how many bytes of memory does that computer have?

8byte addressability: 8bytes can be stored in each memory location. 3bits to access: so 8 memory locations ( 2^3) total size = 8 * 8bytes( each memory location contains) = 64 bytes any queries or discussions, feel free to contact me at: chintala.ganesh@wipro.com

What is the mode of operation for the mainframe computer?
There are 3 'A' modes: A mode = Addressability Mode; refers to address memory on a Mainframe computer. 3 basic Modes: 24, 31, and 64 24 and 31 A modes are becoming obsolete; many newer programming languages, such as Java will have trouble in thier processing routines due to memory and issues. 64 A mode should be the mode of choice, because the mode can handle addressability and memory issue for newer generation proogramming languages.
What is address space?
An address space is a range of discrete addresses, all of the address locations available in a particular named subset of a computer's memory.
What is a phisical address?
In computing, a physical address, also real address or binary address, is the memory address that is electronically presented on a computer address bus circuitry in order to enable the data bus to access a particular storage cell of main memory.
How do you get video memory on a computer?
how can i get the video memory address in computer?.
What is the memory's addressibility?
HI I am Ahtarva,The addressibility is how many bits does that particular processor or micro-controller's architecture use to specify the address of a memory location in the memory. For example if someone say that addressibility is 8 bit then your memory address contains 8 bits and at maximum you have 2^8 different memory locations (or say memory addresses in your device). Here 2^8 is called Address space.
What is the meaning of computer memory?
Computer memory is what data the computer can keep stored. A computer can return to your favorite web address because it is stored in it's memory for example.
What is the role of an address when used in the context of computer memory?
In the context of computer memory, an address is used to access the computer's primary storage memory. These addresses consist of fixed-length digits displayed as unsigned integers.
What is meant by memory address?
A memory address is an identifier for a memory location, at which a computer program or a hardware device can store data and later retrieve it.
What is an Address space?
An address space is a range of discrete addresses, all of the address locations available in a particular named subset of a computer's memory.
How it requires 21 address lines to address two megabytes of memory?
A computer with N address lines can address 2N different objects in memory. 221 is 2,097,152; in a byte oriented computer, otherwise known as two megabytes.
What does it means by relocatable address?
An address that is to be adjusted by the loader when the computer program containing the address is loaded into memory.
What does the number of bits used to represent a memory address determine?
The number of bits used to represent a memory address determines the number of different addresses that can be formed. If the number of bits is N, then 2N addresses can be formed.If N is 16, as it is in the 8085, then 216 = 65,536.If N is 20, as it is in the 8086/8088, then 220 = 1,048,576.If N is 24, as it is in the IBM 360/44, then 224 = 16,777,216.If N is 32, as it is in most 32 bit modern processors, then 232 = 4,294,967,296.If N is 64, as it is in most 64 bit modern processors, then 264 = 18,446,744,073,709,551,616.Note that the amount of addressable memory is not the same as the amount of physical memory. As addressability goes up, often physical memory does not match it, which means that effective addressability is limited.
