The number of memory locations that a CPU with 16 bit program counter can address is?
The number of memory locations that a CPU with 16 bit program counter can address is 65,536. However, the 8086/8088 has a segmented architecture giving a total addressibility of 20 bits or 1,048,576 locations. Without changing the code segment register, though, you can only access 65,536 locations.
What memory locations are the fastest in terms of access solid state drives cpu registers main memory l1 cache?
Cache
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 function of CPU cache?
Many CPUs have what is known as a CPU cache. The function of this CPU cache is to speed up access to data.
What do you mean by interrupt driven input output and programmed input and output?
PIO uses the port access instructions of the CPU to receive or send data. That is also known as polling, since you have to constantly use the CPU to monitor a particular port address. Interrupt driven would use the IRQ controller to access things. The CPU still does the work, but the interrupt calls on the CPU rather than a currently running program doing so.
Advantage of using a CPU register over memory locations?
CPU register is faster than memory loacations
Difference between physical access and logical access between CPU and peripherals?
A logical access assumes that the location to be read or written is contained within a linear address space, while a physical access describes the actual access to the appropriate sector, the location within the assumed linear address space must be converted into the corresponding platter, sector, and track, and the disk hardware must be instructed to access that specific location.
What kind of memory address does a CPU generate?
- An MMU (memory management unit) generates physical address. - A CPU (central processing unit) generates a logical address.
Is CPU needed to access internet?
A CPU is needed to do anything with a computer, including accessing the internet.
Temporarily holds data and instruction as the CPU processes them?
Random Access
How does the CPU communicate with a device?
There is no such thing as a CPU Drive. If you meant "What does a CPU communicate with", then the answer is everything inside your computer.
Difference between direct and sequential access?
RAM or Random Access Memory is used for fast computer memory. The word "Random" is a bit of a misnomer, as there is nothing random about access to this memory. What it actually means is that you can select an address at "random", that is, any address within the capability of the memory, and read or write data to/from that address just as fast as you could read or write data to any other address. In other words, data stored anywhere in the memory can be accessed quickly. Serial memory is different in that access time depends upon where on the medium the data is stored. Examples are magnetic tape, optical disk, magnetic disk. "arbitary access" is not a term used in electronics that I can find. I think it is just another term for "random access".
