Build Your Own Computer – Make the Right Choice

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 recycling service that distributes to schools and other charities that would accept your old computer.

Choosing Parts

Start to make a list of all the components that you need. Before filling in particular model numbers, just make a list with the names of all the components e.g. case, motherboard, CPU, etc.

Now you need to decide on particular brands and models of each component that you have listed. There are several ways to go about this. You can build a computer system around a particular CPU, around a particular motherboard, or around an add-on card such as a professional sound …

Building a Computer for CAD Software

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 store.

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 A Computer

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 you need.

Video is another area that you need to look for. Video cards and monitors are important. If the video card is too small or does not have enough memory and speed, the image on the screen will be of low quality. Because of this when you move items on the screen they will jerk and hesitate. Also in AutoCAD, lines disappear and ghost lines appear on the screen. This will often cause you to “regenerate” the screen when using the software.

The monitor must be no less than 17 “to make using the software rather pleasant. The best size is 20” to 22 “flat-screen monitors. I personally use three 20” monitors on my CAD computer. I use one for text, one for image screens, …

Computer Network Technology

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.

Various Networks

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.

LAN Benefits

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 complex.

3. Wide Area Network (WAN) WAN is a type of network that is usually built through satellite or submarine cable technology. An example of a WAN is a bank network in the capital city that can share information with the regional bank network. They can also hold video conferencing meetings via the Internet.

Advantages of WAN:

 a. We can send files or documents by electronic mail (email) instead of sending documents manually through the post office. b. The network server at the Head Office can be a data bank of a branch office. c. Company data can be updated every day as needed.…

An Eye Opener to Broadband Technology

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 broadband technology.

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 rates.

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 protection.

Such connections may not be possible in remote areas.

You can see that the advantages outweigh the negatives; therefore broadband technology is undoubtedly a boon to today’s fast paced crowd.…
