What is the size of register memory?
Register Memory Registers are memories located within the Central Processing Unit (CPU). They are few in number (there are rarely more than 64 registers) and also small in size, typically a register is less than 64 bits in size.
What is the size of AH register?
al and ah are the 8-bit, “char” size registers. al is the low 8 bits, ah is the high 8 bits.
How many bytes is a RAM?
Typically, computers have much less memory than disk space. A typical desktop computer might come with 32 or 64 megabytes (32 or 64 million bytes) of RAM, and a hard disk that can hold 4 to 80 gigabytes (4 to 80 billion bytes).
How many bytes is SS memory?
A collection of 8 bits is called a byte and (on the majority of computers today) a collection of 4 bytes, or 32 bits, is called a word. Each individual data value in a data set is usually stored using one or more bytes of memory, but at the lowest level, any data stored on a computer is just a large collection of bits.
What are the sizes of memory?
The kilobyte is the smallest unit of memory measurement but greater than a byte. A kilobyte is 103 or 1, 000 bytes abbreviated as ‘K’ or ‘KB’….Types of various Units of Memory-
| Name | Equal To | Size(In Bytes) |
|---|---|---|
| Byte | 8 Bits | 1 |
| Kilobyte | 1024 Bytes | 1024 |
| Megabyte | 1, 024 Kilobytes | 1, 048, 576 |
What is word size in memory?
Fundamental Data Types A byte is eight bits, a word is 2 bytes (16 bits), a doubleword is 4 bytes (32 bits), and a quadword is 8 bytes (64 bits).
What’s the smallest memory size a system can support?
With affordable DIMMS, you’re limited to about half as much (there are only so and so many slots). Generally the smallest addressable size is one byte, as you have calculated it, if it were one byte it would be 2^16*1 = 65536 bytes. However, because on this system there are two bytes per address, it is actually 2^16*2 = 131072 bytes.
How many bytes are in a kilobyte of memory?
The computer represents all characters and numbers internally in the same fashion. In practice, memory is measured in KiloBytes (KB) or MegaBytes (MB). A kilobyte is not exactly, as one might expect, of 1000 bytes.
What’s the maximum amount of memory I can use?
Memory size depends on address bus size i.e. either 16 or 32 or 64 bits. So 2^16 or 2^32 or 2^64 is the maximum main memory supported.
How much memory does a byte take up in Java?
I have heard mixed opinions over the amount of memory that a byte takes up in a java program.
