Cumulative Computer Quiz #1

Ok Beammeuppy, Its been more than 5 days and no one has met all the requirements. So tell us the answer, please.:D
 
It actually surprised me that this question would stand for 5 days.

The company is DEC or Digital Equipment Corporation, as guessed by KaeptnOvi, its founder and one of the greatest IBM haters ever is Ken Olsen who founded DEC in 1957.

It was the first computer company big in size that wasn't an IBM look-alike. Best known products are the PDP and Vax series which were used mainly in non-admin environments. I made my first CAD drawing on a PDP-8 in 1985 or so (64k memory).

DEC was eventually crushed between Intel-based servers and Sun / HP servers and was acquired by Compaq.

Since KaeptnOvi got the name right next question is for him.
 
Oh now I have to think of something intelligent, hmmm, ok here it comes:

What is the Tri-State, explain:
 
Hey C'mon guys it's not that hard, or is it?

Ok, here's a hint: it has something to do with bus architecture...
 
Bus architecture...computers...Tri-State? How are these all connected?:confused:
 
Well with "bus" I didn't mean the big yellow things that drive children to school :D, more like data-bus, adress-bus, etc..
 
Oh, wasn't sure there for a minute!;) You, could have been a little....woozy...
As for the question, hmmm.........dunno.
 
Well, since I study IT, and that is a combination of EE and CS here, I found the question too easy! :p
That´s why I didn´t want to answer yesterday (and it was also more like today 3am when I read it first ;)).

Here goes:

A tristate gate is a logical unit which has an output line that can achieve 3 different states. High, low (binary 1 and 0) and the tristate itself, which switched the gate to a high-impedance state, therefore disabling it.
This third state is achieved by another input line, the CE (chip enable) line. If this line is set to low, then the chip is disabled, therefore not fulfilling it´s logical operations.
In a bus system this is used to enable access for one client only, since the bus can only transmit data from 1 point to another. :yeah:


That should be enough for the basics.
:D
 
Yeah, judged by the sheer mass of replies this question was really way too easy :D

wow, that was much more detailed than I was looking for. All I wanted was that it is for example used for DMA (Direct Memory Access) bypass the CPU. But you want to do it perfect, ok, fine by me :D

Your turn

By the way what is CS (I imagine you're not referring to counter-strike here, and I think EE stands for Electo Engineering (sp?), but I can't find an explanation for CS other than Chip Select which seems not to be applicable here)
 
Electrical Engineering and Computer Science! ;)

Now for my question:

CPU work can be divided into 3 basic steps/cycles. Name them!
:D

1. Fetch instruction from memory

2. Load into ALU

3. Execute.

{Repeat}

Not sure if the nomenclature is right...
 
Not bad, but not what I wanted. :p

You have described a complete cycle, without naming it, but each step here is a seperate cycle in itself, with another global name. And those are still made up of even smaller steps, the last name I want.
So Name those 3 divisions/subdivisions that make up one CPU instruction!

Try again.
:D

on topic: I'm not sure what you mean but I'll give it a shot:

Do you mean:

M1 - OP Code Fetch
M2 - Memory Read/Write
M3 - Memory Read/Write

I think he means things like; even though you have an OP code it needs to be decoded before the correct action can proceed. Different generations of processors have different considerations when executing code so you can get into wait states and UV pipes depending on even how the code was originally compiled.

All micro processors use the same division of steps and cycles that make up one complete instruction. An example of one instruction would be "Write data to memory".

There are 3 divisions of every instruction in every processor that I want! :yeah:

The smallest division of all cycles is the clock of the CPU.
Now I want the name of:

1. The smallest step (equal to one or two clock steps in most CPUs)
2. The smallest cycle (made up of the steps above, describes a subinstruction, complete in itself, one example would be "Get OP-code from memory")
3. The complete cycle of one CPU command (should be obvious)!


After easing this up a little, I also have a bonus question:
What is the cycle "Get OP-code from memory!" called?

As a cycle of the 2nd type, it´s name will also most likely reveal the name of that type.
:D
