What is CS DS ES SS?
In real mode, the registers CS, DS, SS, and ES point to the currently used program code segment (CS), the current data segment (DS), the current stack segment (SS), and one extra segment determined by the programmer (ES).
What is FS and GS register?
The registers FS and GS are segment registers. They have no processor-defined purpose, but instead are given purpose by the OS’s running them. In Windows 64-bit the GS register is used to point to operating system defined structures. FS and GS are commonly used by OS kernels to access thread-specific memory.
What is DS register?
A 16-bit Data Segment register or DS register stores the starting address of the data segment. Stack Segment − It contains data and return addresses of procedures or subroutines. It is implemented as a ‘stack’ data structure. The Stack Segment register or SS register stores the starting address of the stack.
What is non segmented body?
Not composed of or containing segments; unsegmented.
What is CS in assembly?
The CS(code segment register) is used to address the code segment of the memory i.e a location in the memory where the code is stored. The IP(Instruction pointer) contains the offset within the code segment of the memory.
What is SP register?
The Stack Pointer (SP) register is used to indicate the location of the last item put onto the stack. When you PUT something ONTO the stack (PUSH onto the stack), the SP is decremented before the item is placed on the stack.
What are metameres in biology?
Definition of metamere : any of a linear series of primitively similar segments into which the body of a higher invertebrate or vertebrate is divisible.
What is a non segmented?
How many flags are there in flag register?
The flag bits are changed to 0 or 1 depending upon the value of result after arithmetic or logical operations. 8086 has 16-bit flag register, and there are 9 valid flag bits….Status Flags.
| Flag Bit | Function |
|---|---|
| O | The overflow flag is set to 1 when the result of a signed operation is too large to fit. |
What is difference in SP and BP and SS registers?
The register BP, SP, and IP are called pointer registers. BP is base pointer, SP is stack pointer, and IP is instruction pointer. Usually BP is used for preserving space to use local variables. SP is used to point the current stack.
What is ds in ASM?
1) DS = DATA-segment.
What is metameres in biology class 11?
Answer: (b) Metamerism is the division of animal body, externally and internally into segments with a serial repetition of at least some organism, e.g., annelids (earthworm). However, Segmentation refers to the division of animal’s body into a series of repetitive segments.
What are the metameres in earthworm?
Metamerism is the repetition of homologous body segments. This type of development can be seen in the Annelids, which include earthworms, leeches, tubeworms, and their relatives. It is also seen in a more advanced form in the Arthropods, such as crustaceans, insects, and their relatives.
What is segmented and non-segmented?
Those with a single genome segment are referred to as non-segmented, while those with a genome divided into two or more segments are defined according to the scheme by which their genomes are packaged.
What is a virion vs virus?
Viruses are nucleoproteins. They are non-cellular structures with infectious, genetic material. Virions are capsid encapsulated viruses with DNA or RNA molecules. It has both nucleic acid as well as protein layers.
