Discussion Questions Group Work 2
Questions:
- What is a dual-core processor? What advantages does it offer its user?
- Describe how you would select the best DVD burner to meet your needs.
- If cost were not an issue, describe the characteristics of your ideal computer. What would you use it for? Would you choose a handheld, portable, desktop, or workstation computer? Why?
- Your company’s marketing department plans to acquire 150 new computers and monitors, plus several new printers. The marketing vice president has asked you to lead a three-person project team assigned to define user computer hardware needs. Who else (role, department) would you select to be a member of the team? How would you go about defining users’ needs? Do you think that one hardware configuration (computer, monitor, and printer) will meet everyone’s needs? Should you define multiple configuration s based on the needs of various classes of end user?

Question 1's Answer:
Computer
is an electronic device that is designed to work with information. Computer
cannot do anything without a program. Computer takes raw data as input from the
user and processes these data under the control of set of instructions called
program and gives the result and save output for the future use. A typical
modern computer uses LSI Chips.
Standard
computer would recommend for broad deployment in the university’s computer
labs. A standard desktop personal computer is relatively small, inexpensive
single-user computer systems that are highly versatile. Named for their size –
the part are small enough to fit on or beside an off desk, desktop computer can
provide sufficient memory and storage for most business computing tasks.
A
thin client is a low-cost, centrally managed computer with no extra drives,
such as a CD or DVD drive, or expansion slots. These computers have limited
capabilities and perform only essential applications, so they remain “thin” in
term of the client application they include. These stripped-down versions of
desktop computers do not have the storage capacity or computing power of
typical desktop computers, nor do they need it for the role they play. With no
hard disk, they never pick up viruses or suffer a hard disk crash.
Unlike
personal computers, thin clients download software from a network when needed,
making support, distribution and updating of software application much easier
and less expensive. Some organizations are able to take advantage of thin
clients including Fireman’s Fund Insurance Company, which is providing
employees in the field with thin clients to let them make billing inquiries and
view policy data. Other organizations find it difficult to have users accept
thin client, who prefer the features of a full-fledged computer.
In
summary computer have different type and brand for computer labs. The type of
recommend computer is standard computer which has better processor and hard
drive to store all data. Desktop computer cannot be carried to every way
because desktop has big monitor and cpu, while thin client have limited
capabilities and do not have storage capacity.

Question 2's Answer:
A dual
core processor for a computer is a central processing unit (CPU) that has two
separate cores on the same die, each with its own cache. It essentially is two
microprocessors in one. This type of CPU is widely available from many
manufacturers. In a dual core processor, each core handles incoming data
strings simultaneously to improve efficiency.
Advantages:-
An
attractive value of dual core processors is that they do not require new
motherboards but can be used in existing boards that feature the correct
sockets. For the average user, the difference in performance will be most
noticeable during multi-tasking. Servers that are running multiple dual core
processors will see an appreciable increase in performance.
·
Features
Dual
core processors often come with advanced features that single core processors
do not have, such as multithreading. A thread is a single line of data that is
processed by your processor at one time. A dual core processor can thread more
data streams simultaneously. This makes multitasking on your computer easier
because your processor doesn't have to switch back and forth between threads.
·
Affordability
When
you need extra processing power, there are several ways to enhance your
computer. You can purchase a system with two processors and two motherboard
sockets. However, dual core processors are often cheaper alternatives. A dual
processor refers to a computer with two processors, each processor containing a
separate connection with the motherboard. A dual core processor is one single
processor with two processing cores having a single connection to the
motherboard.
·
Better Performance
Dual
core processors report faster speeds than single core processors. When running
a single program, both cores work together to stream data. This allows your
computer to download at faster speeds and run commands more efficiently. Dual
core processors also reduce the need for motherboard fans.
·
Power Consumption
With
two cores running simultaneously, your computer is able to process programs
faster, which reduces the power consumption of your system. This is especially
useful in video and audio editing. You computer may need to run for hours while
a video is rendering. A dual core processor cuts rendering time and saves
energy.
Question 3's Answer:
Selecting
the best DVD burner is subjective. The most important way is to find the needs
when selecting the DVD burner. The first thing is to determine whether an internal
DVD burner is better or if an external DVD burner could meet the needs. If is
it about to share DVD burner with multiple computer, an external burner would
probably function as the best. However, some consumer would select an internal
DVD burner as their needs. I also want to think about whether color matters at
all to me.
Once
the consumer determined what the needs and already willing to purchase, they
have to make sure the purchase is really the best DVD burner for them. You can
do this various way, one of which is to discover and read consumer reviews of
special products you are interested in.
Further
option is to check out your local shop, which sold various electronic products
and accessories and engage a customer service representative to talk about your
choices. It is helpful if you are thinking about the small differences between
special products, but keep in mind that shop sales people are more interested
in selling you something compared to point you in the direction that is good
for you.
In
the conclusion, the best DVD burner, you will look for is one that provides the
specs and reliability you need and expect, while offering a reasonable price
tag to choose it. Make sure it is the case when you are willing to buy, and you
cannot make a mistake. If you buy a product which does not meet all your needs,
possibilities are you will be disappointed, and you will end up on another
search for the best DVD burner sooner than you would like.

Question
4's Answer:
Creating
your own ideal and unique computer is actually possible. By purchasing all the
right hardware, you can assemble your own one of a kind computer.
If
cost were not an issue I would want to be able to design and setup my own
computer; which will be ideal for me and meet all of my need and requirements.
I will use the computer for gaming and surfing the internet, but generally for
gaming; and do assignments if it requires using a computer. I choose the
computer to be portable (laptop), so that I can take it anywhere. Having a
portable computer, this will enable me to take the computer anywhere and the
matter of size means that it will not be space consuming. The downside of
having a portable computer (laptop) is that, if hardware is damaged, you will
have to disassemble the whole computer. This is because everything is assembled
into one packed laptop. A desktop however, has its own monitor, CPU and
keyboard; making it easier to fix the computer if it is damaged.
But
nevertheless, being able to make or create your own computer with no price
restrictions is very favorable.
