Help/test
<div class="IPBDescription">computer quiz</div> Ok so I've got this practice midterm that I can do before the actual one... but there are no answers for it so i have no idea if I am getting the questions right.
If anyone is extremely bored or wants to test their "basic" knowledge of computers please do give me any answers that you think are correct.
You can take the quiz here:
<a href='http://www.usrlocal.ca/~dbm/teaching/CIS1000/Exams/sample1/' target='_blank'>http://www.usrlocal.ca/~dbm/teaching/CIS1000/Exams/sample1/</a>
Any help is apreciated. This isn't my actual test i'm not trying to mooche off you guys, you can check the root page if you don't believe me.

Thanks.

The four basic operations performed by a computer are:
input, processing, decode, output
input, processing, execute, output
input, decode, storage, output
input, processing, output, storage
<span style='color:red'>I personally would say Input, processing, output, storage, but I could be wrong.</span>
Question 2:
A list of instructions written in a programming language such as C or Java is called:
an instruction set
a computer program
the information processing cycle
an Internet application
<span style='color:red'>Computer program.</span>
Question 3:
How many bits are in 2KB (recall that 1kilobyte = 1024 bytes, and 1 byte = 8 bits):
16
256
2048
16384
<span style='color:red'>16384. 2KB = 2048 bytes = 16384 bits.</span>
Question 4:
How many different values can be represented with 7 bits (equivalently how many different “codes” can be made with a set of 7 on/off switches)?
256
128
14
7
<span style='color:red'>128. I thought it should be 64 at first, but I was thinking of the question as "What is the highest binary digit you can get in 7 bits X( </span>
Question 5:
What is the basic unit of information used in a computer?
bit
byte
data
information
<span style='color:red'>Pie. Or bit I suppose. I assume by "basic" unit they mean the smallest.</span>
Question 6:
Arrange the following size prefixes in decreasing order of size: Kilo, Giga, Mega, Tera
Kilo, Mega, Giga, Tera
Kilo, Giga, Mega, Tera
Tera, Mega, Giga, Kilo
Tera, Giga, Mega, Kilo
<span style='color:red'>The first one.</span>
Question 7:
The binary (base-2) value 1101 is what value in decimal (base-10)?
12
13
14
15
<span style='color:red'>Thirteen. 8+4+1=13</span>
Question 8:
The hexadecimal (base-16) value A is what value in binary (base-2)?
1010
1001
1100
1011
<span style='color:red'>The first one. I find it sometimes helps if you convert it to decimal first, A = 10 = 1010</span>
Question 9:
What is the difference between RAM and ROM?
ROM is faster than RAM
RAM is faster than ROM
ROM is volatile while RAM is non-volatile
ROM is non-volatile while RAM is volatile
<span style='color:red'>Uh oh. I don't remember being taught the term "volatile", but what they're asking is "which one can't be written on", and the answer is ROM.</span>
Question 10:
What is used to connect external devices to the computer?
backbone
dongle
bus
port
<span style='color:red'>AHAHA he said dongle! Its a port.</span>
Question 11:
What is a key difference between CISC and RISC based microprocessors?
the instruction set for a CISC processor tends to be larger and more complex
the instruction set for a RISC processor tends to be larger and more complex
CISC processors have less special purpose circuits
RISC processors have more special purpose circuits
<span style='color:red'>Arr, ok, this one has me stumped. I remember being taught this, but I never needed it again <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile-fix.gif' border='0' style='vertical-align:middle' alt='smile-fix.gif' /><!--endemo--> </span>
Question 12:
What is cache used for?
holds often used data or program components
interfaces with the cooling system
assists with connection of external devices
adds extra resources for the operating system
<span style='color:red'>Probably A, although it <i>might</i> be D so don't hold me to that.</span>
Question 13:
A read/write armature (arm) on a disk drive is mechanically most like a:
tape recorder read/write head
record player arm
laser
tape backup unit
<span style='color:red'>Lets all pretend I know this one, because I really should, but don't. Either A or B.</span>
Question 14-17 refer to the following file hierarchy shown as a tree (underlined entries are directories):
Question 14:
What is the name of the root directory?
\
.
^
&
<span style='color:red'>A</span>
Question 15:
Assuming that the current directory in the above picture is the one named “bill”, which of the following commands would change the current directory to be the one named “bin”:
cd bin
cd .\..\..\bin\.
cd ..\bin
cd ..\..\bin\..
<span style='color:red'>C</span>
Question 16:
How would we refer to the file “proposal.doc” using its absolute pathname?
proposal.doc
home\mary\proposal.doc
\home\mary\proposal.doc
mary\proposal.doc
<span style='color:red'>C again.</span>
Question 17:
If you are currently in the directory called tmp and execute the following command: “mkdir \new”, what will happen?
a directory called new will be created inside the current directory
a directory called new will be created in the root directory
a directory called new will be created in the home directory
a directory called new will not be created
<span style='color:red'>A</span>
Question 18:
The problem with the use of a file allocation table (e.g. FAT16 or FAT32) for keeping track of files on a disk is that as the disk (or partition) gets larger, the clusters in which we store the files:
become smaller
stay the same size
become larger
no longer exist
<span style='color:red'>C. I think.</span>
Question 19:
Consider the following list of file names: file1.txt, file1.TXT, FILE1.txt, FILE1.TXT; how many different files would we be referring to under UNIX?
1
2
4
those are not valid file names under UNIX
<span style='color:red'>I really don't like unix, so don't hold me to this, but i'm pretty sure its 2; unix is case sensitive, but the extensions shouldn't be.</span>
Question 20:
File names under Windows are:
case-sensitive
case-preserving
case-centric
case-causing
<span style='color:red'>Whichever one means "Not case-sensitive"</span>
Ok, i'm bored now <!--emo&::nerdy::--><img src='http://www.unknownworlds.com/forums/html/emoticons/nerd-fix.gif' border='0' style='vertical-align:middle' alt='nerd-fix.gif' /><!--endemo-->
Anyone care to continue where I left off, and correct any noobish mistakes I made?

anythin with a question mark is best guess. C is technically inarcurate because the terms were redifined almost a decade ago.

Extentions don't exist in UNIX as they do in windows. UNIX is case sensitive in every respect, so there are 4 different files there. 17 is also wrong, the \ specifies the root directory. 15 is wrong, you need to backreference 2 directories not just one.

Probably they mean a byte, but bit could also be correct under a different interpretation.
Arrange the following size prefixes in decreasing order of size: Kilo, Giga, Mega, Tera
Kilo, Mega, Giga, Tera
Kilo, Giga, Mega, Tera
Tera, Mega, Giga, Kilo
Tera, Giga, Mega, Kilo
<span style='color:red'>The first one.</span> <!--QuoteEnd--> </td></tr></table><div class='postcolor'> <!--QuoteEEnd-->
Wouldn't it be D because it says "<i>in <b>decreasing</b> order of size</i>"?
What is the name of the root directory?
1. \
2. .
3. ^
4. &<!--QuoteEnd--></td></tr></table><div class='postcolor'><!--QuoteEEnd-->
5. /
