Computer Awareness Question and Answers
Q1. What is the
configuration of PC?
Ans.:
Configuration can refer to either hardware or software, or the combination of
both. For instance, a typical configuration for a PC consists of 32MB
(megabytes) main memory, a floppy drive, a hard disk, a modem, a CD-ROM drive,
a VGA monitor, and the Windows operating system.
Q2. What is Device
Manager?
Ans.:
Device Manager is an OS feature that lets you view and change the properties of
all devices attached to your computer.
To
get to the device manager in Windows, right click on the My computer icon,
choose properties, then click on the device manager tab. From there you can
select a variety of management options.
Q3. What is an
Operating System?
Ans.:
An operating system (OS) is software, consisting of programs and data, that
runs on computers and manages the computer hardware and provides common
services for efficient execution of various application software.
Examples
of popular modern operating systems for personal computers are Microsoft
Windows, Mac OS X, and GNU/Linux
Q4. Difference between
window vista and window XP?
Ans.:
Windows XP was released in 2001.
Windows Vista was released in 2007.
Overall,
XP is more reliable, more user friendly, and has been around for a while so it
has a large user base that can answer most questions about Windows. XP is also
more compatible with printers, copiers, etc. XP also does not have User Account
Control (UAC) which is a pain in the butt for Vista users. UAC asks you a
question every time you do something, literally. For example, if you move something
in the Start Menu, UAC will come up in a dialog box which takes you out of you
work environment and says "Do you want to move this over there?"
Basically, if you do something, Vista will ask you if you want to do it.
Vista
on the other hand, has Direct X 10, which allows you to have more sophisticated
graphics in games. Vista's desktop is graphically enhanced with 3D technology,
which is basically the largest advantage that Vista has over XP. Vista has some
minor advantages like faster loading of the Start Menu and quicker booting and
shutdown.
Q5. What is Core2
and Quad Processor?
OR
Q.What is Intel®
Core™2 Quad Processor?
Ans.:
Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64
single-, dual-, and quad-core microprocessors based on the Core micro
architecture. The single- and dual-core models are single-die, whereas the
quad-core models comprise two dies, each containing two cores, packaged in a
multi-chip module.
Q6.What is the
meaning of Duplex Printing?
Ans.:
Component of a printer that allows for both sides of a page to be printed at
the same time. The duplexer typically comes as an add-on accessory to a printer
and attaches to the printer to allow for double-sided simultaneous printing.
A
printer with a duplexer installed often is referred to as a duplex printer.
Q7. What is
Hibernation?
Ans.:
Hibernate mode is a special form of shutdown in which the current state of the
computer is saved to disk, and the computer is powered down. When a computer
resumes from hibernation, it reads the saved state data and restores the system
to the same state. Programs that were open are restarted and network connections
are restored.
The
ability to hibernate is not enabled by default. To enable hibernate support:
1) Control Panel / Power Options /
Hibernate tab.
2) Check the Enable hibernate
support box.
3) Press Apply and OK.
Q8. How to access
network?
Ans.:
An access network is that part of a communications network which connects
subscribers to their immediate service provider. It is contrasted with the core
network, for example the Network Switching Subsystem in GSM. The access network
may be further divided between feeder plant or distribution network, and drop
plant or edge network.
Access
process
The
process of communicating with a network begins with an access attempt, in which
one or more users interact with a communications system to enable initiation of
user information transfer. An access attempt itself begins with an issuance of
an access request by an access originator.
An
access attempt ends either in successful access or in access failure - an
unsuccessful access that results in termination of the attempt in any manner
other than initiation of user information transfer between the intended source
and destination (sink) within the specified maximum access time.
Access
failure can be the result of access outage, user blocking, incorrect access, or
access denial. Access denial (system blocking) can include:
Access failure caused by the issuing of a
system blocking signal by a communications system that does not have a
call-originator camp-on feature.
Access failure caused by exceeding the
maximum access time and nominal system access time fraction during an access
attempt.
Q9. How to check IP
address?
Ans.:
Command for Windows 2000 / XP / Vista
•Go
to Menu Start and select Run . Then, type the following command:
•cmd
/k ipconfig /all
Q10. How do you
check size of RAM?
Ans.: procedure:
Go
to my computer and right click on it.
It
should show all the properties like RAM size, Hard disk Size etc.
C Program to Calculate Sum & Average of an Array
#include
<stdio.h>
#define MAXSIZE 10
void main()
{
int
array[MAXSIZE];
int
i, num, negative_sum = 0, positive_sum = 0;
float total = 0.0, average;
printf ("Enter the value of N \n");
scanf("%d", &num);
printf("Enter %d numbers (-ve, +ve and zero) \n", num);
for
(i = 0; i < num; i++)
{
scanf("%d", &array[i]);
}
printf("Input array elements \n");
for
(i = 0; i < num; i++)
{
printf("%+3d\n", array[i]);
}
/* Summation starts */
for
(i = 0; i < num; i++)
{
if (array[i] < 0)
{
negative_sum = negative_sum + array[i];
}
else if (array[i] > 0)
{
positive_sum = positive_sum + array[i];
}
else if (array[i] == 0)
{
;
}
total = total + array[i] ;
}
average = total / num;
printf("\n Sum of all negative numbers = %d\n", negative_sum);
printf("Sum of all positive numbers = %d\n", positive_sum);
printf("\n Average of all input numbers = %.2f\n", average);
}
