What are segment registers?

In the x86 processor architecture, memory addresses are specified in two parts called the segment and the offset. One usually thinks of the segment as specifying the beginning of a block of memory allocated by the system and the offset as an index into it. Segment values are stored in the segment registers. There are four or more segment registers: CS contains the segment of the current instruction (IP is the offset), SS contains the stack segment (SP is the offset), DS is the segment used by default for most data operations, ES (and, in more recent processors, FS and GS) is an extra segment register. Most memory operations accept a segment override prefix that allows use of a segment register other than the default one.

How many registers are there in x86?

Considering "x86" ranging from 8086 up to 80486 (ok, Pentium too) 32-bit CPUs ,there are 29 registers , as follows :EAX, EBX, ECX, EDX, ESI, EDI, ESP, EBP, EIP, CS, DS, SS, ES, FS, GS, "Status(Flags)-Register" CR0, CR2, CR3, TR4, TR5, TR6, TR7 DR0, DR1, DR2, DR3, DR6, DR7Alexandre Botaohttp://www.botao.orgbotao@unix.sh


What is the difference between the Air cadet gliding scholarship - flying scholarship and air cadet navigator - and can you do them all?

the difference between a GS (gliding scholarship) course and a Flying scholarship, is the aircraft that is used, the Vigilant or viking for the GS and the tutor/Cessna type light aircraft/microlight (depending on type of FS). another difference is the availability, the GS is done at a lot of RAF and civilian airfields, whereas (somebody correct me if I'm wrong) the AEF and light aircraft types of FS are only done at Tayside Aviation (nr Dundee, Scotland and some other international bases, I.E. RAF akrotiri, Cyprus) you can definitely achieve GS and FS, unsure on cadet Navigator, i am looking into that myself... hope this helps


What is flat memory model?

A program written in native 32 bit Windows format is created in what is called FLAT memory model that has a single segment, which contains both code and data. Such programs must be run on a 80386 or higher processor. Differing from earlier 16-bit code that used combined segment and offset addressing with a 64 Kb segment limit, FLAT memory model works only in offsets and has a range of 4 Gigabytes. This makes assembly code easier to write and the compiled (assembled) code is generally a lot faster than the equivalent 16-bit code. All segment registers are automatically set to the same value with the flat memory model. This means that segment / offset addressing must NOT be used in 32-bit programs that run in 32-bit Windows operating systems. For programmers who have written code in DOS, a 32-bit Windows PE (executable) file is similar in some respects to a DOS COM file - they have a single segment that can contain both code and data and they both work directly in offsets. That is, neither uses segment / offset addressing. Flat-model assembler code defaults to NEAR code addressing and NEAR data addressing within the range of 4 gigabytes. The FS and GS segment registers are rarely (if ever) used in application programs but may be used in some instances by the operating system itself.
