Before building a new computer, you have
to decide what to use it for. This will allow you to allocate your budget to
buy special equipment where needed. For example, if you plan to play a lot of
games, you will need a powerful graphics card, lots of memory, a large hard
drive, and a special controller. If the computer is going to be used for word processing
and surfing the net, your graphics card doesn’t need to be so powerful and you
won’t need as much storage capacity as graphics.
Computers built for special purposes such
as video editing and sound recording have there owned particular requirements
in the form of add-on cards to process midi files, graphics and sound. These
cards usually mean a top of the line computer to handle special requirements of
the CPU or motherboard.
Re-using Old Parts?
Can you salvage parts from the old
machine? This depends mainly on its age. If it is more than five years old you
would probably be better using all new components. Wear and tear on the
computer components and the advancements in computer technology do nor warrant
using old parts.
Floppy disks are almost at the point of
obsolescence, but you may need one occasionally. Better still copy and transfer
all of your floppies to CD format.
If you have a computer that is less than
two years old, there may be components that can be used on your new machine.
Maybe the hard drive can be installed as a secondary drive and a CD player or
DVD player might be suitable for your needs.
You better buy a new one. It’s usually not
a good idea to reuse a motherboard, CPU, or memory. All of these components are
continuously enhanced If you can find a computer …
Most computers used to run CAD software
must be expensive. But if you use the Autodesk AutoCAD product software then
you really can get by with one from a local department store or a discount
store. One shop where I buy a lot of machines is a small discount grocery
Follow The Minimum Requirements To Run The Software
All you need to remember is that you
follow the minimum requirements to run the software. You can find out the
specifications on the Autodesk site. I have been told that if you want to have
the best CAD computer, you have to spend thousands of dollars. That’s true if
you just want to have the best around. Like a car, you can buy expensive luxury
models or just buy cheaper ones that get the job done.
Computer Games Are More Enough
To Run AUTOCAD
Most computers sold today are designed to
play high-end video games. This computer is in many cases more than enough to
run AutoCAD. If you want to run Inventor software packages for example then you
will need a better the computer and plenty of drive storage space. You will
also need more memory installed on the computer. I suggest you find a computer
expert to help you buy the computer to run Inventor.
What Will You Look For Buying
What you will look for is computer speed,
hard drive size, and the amount of memory installed on the computer. You also
want to be able to expand the amount of memory permitted by the computer
because over time the increase in the program will determine how much memory
Video is another area that you need to
look for. Video cards and monitors are important. If the video card is too
small or …
What is a computer network? A computer network is a set of computers,
printers, and other devices that are connected to each other to share
information and move data through cables. Many users can print with the same
printer or use the same software at the same time. Computers that store primary
data and act as data centers are called Servers, while computers that are
connected to networks and retrieve data from Servers are called Workstations.
1. Local Area Network (LAN) A network that is limited by a small area
usually used by a small office in a building or school. Usually not far from 1
km square. Most LANs use cables and LAN cards to connect one computer to
another. Each computer that is connected to a LAN has a different Internet
Protocol Address. Usually abbreviated as IP Address. LAN can also be set up
through Wireless Technology which has speeds of 10 to 10,000 Mbps. Wireless
LANs can use infrared or radio frequencies.
a. Sharing files and printers is easy between computers. b. The risk of
data loss caused by a virus can be reduced. c. If there is one computer
connected to the modem, all computers can access the internet. d. There is a
lot of space in the storage system (hard disk) for storing documents. e. Files
stored on the server can be accessed by client computers with authorization.
Authorizations can be made according to the company’s organizational structure.
2. Metropolitan Area Network (MAN) This type of network usually has a
larger area than a LAN or can contain networks from several LANs that are
connected to each other. Example MAN is a network built on a broad campus
3. Wide Area Network (WAN) WAN is a type of network that …
Broadband refers to a high speed form of telecommunication ion which
several frequencies are used to transmit information. The availability of a
wide band of frequencies makes it possible to send large amounts of data
through the various channels embedded within the band. This helps in saving a
considerable amount of time. A broadband
connection has marked advantages over other forms of net access media like
dial-up. Some of them are:
Gone are the days when you have to sit in front of your system for hours
together to download a single document. Now with broadband technology you can
get scores of data in a matter of minutes and seconds. Broadband speed is tons
of times faster than other types of net connections especially dial-up.
How do you think all the gaming centers prosper these days, downloading
complex, tricky games from the internet would not have been possible without
Previously with the dial-up net connections which were accessible
through the phone lines, there was the disadvantage of keeping the phone
engaged all the while the net was on. But broadband is available through a
separate cable with no connection with your telephone line.
It provides ‘anytime access’ since you can leave it on for hours.
There are attractive packages offering unlimited access for reasonable
Nowadays broadband technology also makes phone services possible through
cheap VoIP technology.
All said and done broadband services are not without apparent faults. A
look into some of the negatives:
Broadband connections can be more expensive than dial up in some cases,
however when separate lines are used the costs can be offset.
Leaving your system with net access on all the time can make it more
susceptible to hackers. You will have to create a personal firewall as
Such connections may …
In our PC engineering program, you will create a strong understanding of not only laptop systems, but also of the engineering fundamentals required to make computer technology options for genuine-world engineering challenges. Minimum Educational Requirement: To turn into a computer programmer, most candidates need to have a bachelor’s degree in an location of computer system science.
