Tips For Upgrading Your Computer's Memory

One of the most common computer repair tasks involves upgrading your computer's memory. There are lots of reasons you might want to do a little upgrading of this nature. For example, more memory means a faster processing time. From faster loading for web pages to better gaming, it can certainly enhance your overall computing experience. More memory also means that your computer is able to easily move from application to application without a hitch. If your machine is networked, you'll experience a higher level of efficiency, and even if you're not, you'll certainly noticed better printing capabilities when you install more memory. The best news, though, is that upgrading your computer's memory is not only a fairly common computer repair task, it's an incredibly easy one.

The first step is to figure out how much memory your machine has. Right click on your 'My Computer' desktop icon. Choose 'Properties' The first tab you see should say 'General' and at the bottom of that tab, you may notice how much RAM (Random Access Memory) your computer currently has. That's an important number in this equation, and if you think you can't remember it, it might be best to write it down.

The second step is to understand how much memory your computer is capable of holding. Different computers can take on different memory capacities, but exceeding your computer's memory capacity can be dangerous, and all in all, it's a waste of your money to use more memory than your computer can hold. There are a couple of ways to go about this. First, there are some free online scanners out there that will let you know what your computer's memory capacity is, but some of them come with embedded bugs, so it's important to be careful. Another option is to glance at the manual that came with your machine. It should give you some good numbers. Alternately, you can log onto the computer manufacturer's website to get the specs for your individual machine.

There's one more part to this equation before you can rush out and buy the memory your computer needs for an upgrade. You may have come across this already if you've been reading your computer's manual, but if you haven't, you must get this information before you make any purchases. Understand what kind of memory your computer needs. Some machines have SDRAM. Others have DDR. Older machines have EDO or FPM. In order to determine what type of memory your machine currently has, you'll need to either consult your computer's manual, the manufacturer's web site or you can scan your computer with one of those free scanners.

Now you are ready to make a purchase. You have to decide how much memory you want on your computer. Of course, during this process, you should keep in mind how much your machine can hold, but if you're a basic user, you're probably going to want to run at least 256 MB. If you're a bit more advanced, and you use your machine for images and video on a regular basis, you may want to head into 512 MB land. If you are heavily into graphic design, head up toward a gig or so.

Once you've made your purchase, it is time to install it into the computer. Turn your machine off, and be sure it is unplugged. Take the case off. Find the memory slots. If you are taking out your old memory, press the ejector clips, and the stick will pop out. You're ready to put your new memory sticks in, and you can do this by finding the notch on the module's pin-side. They'll line up with the socket for the memory, put it in, and press firmly. The ejector clips will lock in around your new memory stick. Turn your computer back on, and you should be ready for a faster computing experience.

How to Connect a USB Modem Wireless Router Ethernet

I currently have a USB broadband modem. I purchased a wireless router which has ethernet connections. Currently, the modem is plugged into my computer downstairs which is running Windows 98, therefore, it won't bridge the connections to my computer upstairs(XP). I can't update to XP because a family member wont 'risk' it.

Can I connect the USB broadband modem to my wireless router using a complicated selection of cable adapters ie ethernet to USB (I cant find a USB TO ETHERNET adapter). If this is not possible, if I plug the USB modem into my XP computer, can I bridge the connections to my Win 98 computer using the XP computer as the host?

I think their is Ethernet to USB out their currently but not USB to ethernet. I dont see any reason why you should not be able to hook up your USB modem to your XP computer and use it as a bridge to the 98 computer.

Of course, it would be nicer to have an all-in-one unit, but you can accomplish your goal with this equipment. You cannot use cable adapters to convert the modem's USB into Ethernet. USB needs drivers to operate, and Ethernet connections do not provide those drivers to the device. you could also connect the modem to the XP machine and bridge connections, yes. but you can leave the system the way it is and configure it to run smoothly like this:

If I had the hardwear in front of me, it would be easier to provide specifics... but i can probly give you an idea of what to do. There are only 2 steps here:

1. configure an internet gateway.
2. configure the router.
And the rest is easy.

1. Set up the internet machine to SHARE AN INTERNET CONNECTION (you can use the wizard if you want, or just enable Internet Connection Sharing), which will turn the 98 into an internet gateway. that gateway needs an IP address designated, however. In essence, the 98 machine will be the internet server, so the IP of the 98 machine is the IP of the gateway. Assign an address, for example: 192.168.1.1 to the 98 machine. the "192.168" is important, and the last strings you can stretch on, but for the sake of ease lets keep it small. *TIP* the subnet mask will always be 255.255.255.0. okay that takes care of the host machine.

2. after you have an internet gateway, connect the wireless router, and console (or IP) in to the settings, usually by going into internet explorer and typing 192.168.0.1 into the address bar, and look for a slot for Internet Gateway. Type the address assigned in step 1. thats that for the router. (there may be other settings necessary for your specific network, and if there are, be sure to configure those.)

Lastly a few housekeeping tasks. make sure the workgroup for both machines is identical. I usually use MSHOME as the workgroup. Also make sure that on the XP machine, your IP address is set to "Automatically Obtain IP address", also known as DHCP.
