What is BIOS?

B
:
The Basic Input
-
Output System (BIOS) is an essential set of routines in a PC, which is stored on a
chip on the
motherboard
. It acts as an intermediary between a computer's hardware and its operating
system. Without the BIOS, the PC's operating system would have no way to communicate with, or take
control of, the hardware.

In other words,

By how much could incorrect BIOS slow a PC?

A:

the BIOS is

a crucial component of any computer. If its options are set incorrectly,
the BIOS could slow your computer down by as much as 40%. Unfortunately, as new
processors and motherboard chipsets are released, BIOS options continue to get even
more confusing. As

a result, many seasoned technicians are still baffled by the jargon
-
laced and confusing options available in a modern computer's BIOS setup program.


Give an example of a BIOS update procedure

A:


Step 1: Identify your current BIOS version

Step 2: Check
your PC/motherboard manufacturer's Website for BIOS updates.

Step 3: Read the included documentation

Step 4: Update your BIO

ackup procedures

A:

The computer hard drive that stores all your data has moving parts, and in

time your hard drive will wear out
and fail. It's just a matter of when. You need to keep a copy of all your important data somewhere else.


Apart from hard drive failure, there are many other likely scenarios that may result in the loss of your valuable

files like power failures and spikes, or system and file corruption due to viruses, worms, or other malicious
attacks.

Backup Location

You need to store a copy of all your important files in a
different location to where your computer is situated. It's
not a great deal of use having the copy of your files on your
external hard drive which is constantly plugged into your
computer. A thief won't leave your additional drive for you
to recover your lost files, a fire or flood won't distinguish
between your c
omputer and your external drive. At the very
least, keep your copy in a different location in your home. If
possible, keep your backup copy in an entirely different
building.

Some choose to backup their data onto remote servers via
File Transfer Protocol (
FTP) or by other means. Others use
the services of off
-
site backup over the Internet. Be mindful
however that your data is your responsibility. The moment
you transfer that data to a third party to keep safe, new
risks involving the potential compromise of

that services'
availability and security arise.

PC
diagnostic software and hardware

A:

Windows isn't just for hard
-
core geeks or just for novices. Being the most popular
operating
system on the planet, Microsoft must design it to fit the widest possible
range of users. Even its "techy" parts, like the Task Manager, sometimes need to be
toned down for general consumption. But what if Windows were aimed only at the most
technical of u
sers? Process Explorer is the Task Manager that could have been.


Process Explorer offers a wealth of information about every process running on your
computer.Process Explorer can do all kinds of tricks that Task Manager just can't do.
Case in point: Fire
up Task Manager right now (hit Ctrl
-
Shift
-
Esc), and click "Show
processes from all users." You will doubtlessly see a bunch of processes called
"svchost.exe," all helpfully labelled "Host Process for Windows Services." Great, but
what are those services? W
ith Process Explorer, you can find out just by mousing over
the process name.


This may sound like an obscure technical detail (and it is, a little bit), but it can also be
very useful. For example, on my system there's a single svchost.exe process taking
up
over 250MB of RAM
--
a sizable chunk by any measure. Thanks to Process Explorer, I no
longer have to wonder what all that memory is used for: I know exactly what services
hide under that process, and can disable them if I want to.


Another very neat Proce
ss Explorer capability: graphing GPU usage. Task Manager's
Performance tab lets you see CPU and RAM usage only, but if you have a discrete
graphics card, you have at least one more powerful (if dedicated) processor. Monitoring
the GPU is useful not only fo
r benchmarking games, but also for keeping an eye on
applications such as Bitcoin or BOINC that use the GPU for general
-
purpose
calculations. You can also see how much of the GPU's dedicated memory is used.


When going over the list of currently running pr
ocesses, unfamiliar names will
doubtlessly pop up. For example, do you know what csrss.exe is? I can guarantee this
process is running on your system right now, under the nebulous description "Client
Server Runtime Process." With Process Explorer, you just

need to click the process and
press Ctrl
-
M, and Process Explorer will instantly search Google for that process name.
It's a very handy way to find out what's what in that long list.


Here's another classic Windows annoyance: You're trying to delete or
overwrite a file,
but Windows insists the file is in use. Process Explorer lets you see exactly what files
are used by every process in your system, and also search for a file or DLL. In other
words, you can track down the process that is using that file a
nd kill it if you want to.


Process Explorer looks a bit intimidating at first, and it's an acquired taste. You can
start off by using it just like Task Manager and gradually grow into its unique
capabilities. It even has an option called "Replace Task Man
ager." Once you use Process
Explorer regularly, you may well use that option. Highly recommended.




(Computer) H
ardware maintenance

A
:

Computer hardware maintenance involves taking care of the computer's physical
components, such as its keyboard, hard dri
ve and internal CD or DVD drives. Cleaning
the computer, keeping its fans free from dust, and defragmenting its hard drives
regularly are all parts of a computer hardware maintenance program.

Activity 2

Q1:

What is HirensBootCD?

A:

Hiren's BootCD

(also known as HBCD) is a bootable software CD containing a number
of diagnostic programs such as partitioning agents, system performance benchmarks,
disk cloning and imaging tools, data recovery tools, MBR tools, BIOS tools, and many
others for fixing va
rious computer problems. Many people consider HBCD an invaluable
tool[2] for use in troubleshooting and recovery of computers; however, due to a
questionable past, it has received little press.

Give an independent

review

of HirensBootCD as a diagnostic utility.

This program looks very useful. There are a large number of different diagnostic tools
covering a range of areas, like systems analysis and virus

scanning.

What are some of the technical risks with this project?


A:

The technology will

need to be portable and able to withstand the rigors of travel in
remote areas. Battery time is also a risk as we are in remote areas and electricity may
not always be available.
