hi
the following are sample of A+ exam questions. I took them from a CD
which to prepare for A+ exam. Any help with these question would be
very much apprciate it..thanks

1) ------ are circuits that enable data, instructions and power to
move from component to component on the system board

a) Traces (correct answer)
b) Grid lines
c) Expansion slot
d) Adapter cards

My question what is Traces??

2) Primary storage is temporary?
a) True (correct answer)
b) false

what is primary storage.. is not harddrive primary storage.. how come
it is temporary??

3) The two types of microchips manufactured are ---- and ---
a) CPU, CMOS (correct answer)
b) TTL, CMOS
c) TTL, CPU
d) CPU, ROM

I thought (b) should be the correct answer

4) The most popular printers today are laser, inkjet and line printers
a) True
b) False (correct answer)

Why flase??

Uh.... Traces "are circuits that enable data, instructions and power to
move from component to component on the system board".

Think about the function, then look at your motherboard. Then look at the
lines connecting things.... that almost look like they were traced onto
the MB.... ;)

Must not have studied very hard yet if you haven't read that Primary
memory is RAM...

Just a guess, but when was the last time you bought a line printer?

I think the "question" answers your question pretty well. If you look
at a circuit board, and ignore the components, you'll see some metal
lines etched into the board itself. These are the tracings. They're
used in lieu of wiring to electrically connect components to each
other.
2) Primary storage is temporary?
a) True (correct answer)
b) false

Primary storage is system memory. Typically system memory is what's
called volatile memory. That means that it only "remembers" stuff
when it's powered up. Interrupt the juice, and it's all gone. It is
theoretically possible to construct a machine that uses non-volatile
memory types, but with current technology, such a machine would be
slow, and very expensive. Just price the difference between a flash
RAM card for a digital camera vs an equivalent sized stick of DDR or
even RDRAM.

So did I, but I guess it might depend on your interpretation of "TTL".
One interpretation could be that TTL encompasses CPUs and CMOS as
well. Then B&C are like disqualified, as they're not really listing
two different types, just a type and a subtype (eg. Two types of fruit
are Oranges, and Naval Oranges).
4) The most popular printers today are laser, inkjet and line printers
a) True

Line printers. I'm not really sure what that is, but as I haven't
seen any ads for them in the last few years, they can't be all that
popular. If I had to guess, it would be inkjet, laser, and dot
matrix impact. Inkjet because covering homes. Lasers covers
offices. Dot matrix impact covers warehouses, and some retail
outlets, as until recently, it was the only type that could handle
duplicate or triplicate carbons paper.

Thin copper lines on the board which connect pins of a component to
other pins of other components to form the physical ewlectrical
connection required. When a circuit board is made, the blank comes as a
solid copper plated sheet. All the "traces or tracks" are imprinted on
it with etch resistant ink/paint etcthe excess copper is etched away
with acid leaving the traces behind.

Line printers are seldom used and the inkjet is more popular than the
laser.
 
3 (b) can't be right because it excludes GaAs technology, ECL, nMOS, etc.
But all the other answers are equally bad.

Don't put too much faith in those practice exams. I took a few practice
exams before I sat for the A+ exams. I couldn't find a single practice exam
without at least ONE wrong answer. That is, the answer listed for the
practice exam question was WRONG.

When I sat for the actual exams, there were only about 3 or 4 questions on
the actual exams that were anything like questions on the practice exams.
Either you're ready for the A+ exams or you aren't. The practice exams
won't help. Practical experience with hardware will help a lot,
hough. -Dave

Copper traces on the board. Buses seems like a better answer.

TTL and CMOS are two types of IC.

CMOS is most definitely not TTL. They are different types.

Traces are technically not circuits. They don't form a complete loop without
components in most cases.

The question is true if you consider the set of the 3. What is left out?
Daisy wheel, thermal, maybe. Perhaps the question is true with an "or" and
false with an "and."

My question what is Traces??
Click to expand...

connections between components (called traces)

This is more traditionally called the Bus or a bus.

Traces are the thin lines for communication and power on the
motherboard or circuit board. The key words is component to
component.
2) Primary storage is temporary?
a) True (correct answer)
b) false

what is primary storage.. is not harddrive primary storage.. how come

Click to expand...

Primary storage is the first storage encountered by a CPU it can be
processor registers, Cache, or Memory. It has always been temporary.
3) The two types of microchips manufactured are ---- and ---
a) CPU, CMOS (correct answer)
b) TTL, CMOS
c) TTL, CPU
d) CPU, ROM
Click to expand...

TTL is transistor to transistor logic or communication between two
transistors it is more of a circuit than a microchip.
I thought (b) should be the correct answer

4) The most popular printers today are laser, inkjet and line printers
a) True
b) False (correct answer)
Click to expand...

Line printers are not used much. Even mainframe printers are more
popular. Almost all businesses use Laser. We even uses lasers with
our mainframe.

But are all traces busses? I didn't think so...

Could be wrong though ;)

To that must be added thermal printing and dye sublimation. Many
companies still use dot matrix printers for multipart stationery.

For what it's worth, I think if anyone managed to pass this exam and
never had any hardware experience, they still would not be able to build
a computer.

Most of it seems so irrelevant these days. Must be another cash cow for
companies to profit on training and literature.

What the heck is a line printer? I thought dot matrix would fall under that
term. Perhaps they mean the old daisy wheel.

Buy some spare parts and build a few computers, or at least modify them. In
the US places like retrobox.com, compgeeks.com, and others have cheap parts.

A + may be useful, I don't know. But I'm suspicious of other comptia certs
e.g. Linux +.

Daisy wheel IS a line printer, and for all intents and purposes,
thernal is too.

Showing my age a bit here, but a line printer is one that prints a whole
line in one go. This is usually a large revolving drum that has the type on
it in several spirals with hammers behind the paper that hit the paper onto
the drum via an inked ribbon. Manufacturers are folk like Data Products.
These guys can work at verrrrrry high speed - typically 1200 to 3000 lines
per minute and are always 132 columns continuous feed paper- not yer usual
A4 or foolscap job.

A daisy wheel printer doesn't work in the same way: these print a character
at a time and the head moves across the paper.

NO IT ****ING ISN'T. I swear to God if one more person calls them a BUS
I'm going on a shotgun rampage.

So what you're telling me numbnuts is the trace between a capacitor and
a resistor is a bus?
