Question by : computer ram pricing help? i need to upgrade my ram i only have 192mb atm i want to upgrade to 2gb it has to be cheap cause i dont have alot of money atm.. anyway idk what im looking for so if someone could tell me what kind of ram i need and the cheapest one i can use from like bestbuys.com or radioshack.com tysm for your help(if u find one please post the link thanks) also its a comaq desktop windows xp about 6years old or so..idk if you need to know that or not. Maximum Memory Capacity: 2048MB Currently Installed Memory: 256MB Available Memory Slots: 1 Total Memory Slots: 2 Dual Channel Support: No CPU Manufacturer: AuthenticAMD CPU Family: AMD Sempron(tm) Processor 3000+ Model 12, Stepping 0 CPU Speed: 1808 MHz Q: Will my system recognize the maximum upgrade? A: Possibly How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found at http://www.crucial.com/kb/answer.aspx?qid=4251. Q: What memory goes into my computer, and can I mix speeds? A: DDR memory with support for DDR PC3200 speeds. Because DDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible DDR speeds listed below, even if your manual calls for PC1600 or PC2100 speeds. Q: How much memory can my computer handle? A: 2048MB. Adding the maximum amount of memory will improve performance and help extend the useful life of your system as you run increasingly demanding software applications in the future. Q: Do I have to install matching pairs? A: No. No, you can install modules one at a time, and you can mix different densities of modules in your computer. But if your computer supports dual-channel memory configurations, you should install in identical pairs (preferably in kits) for optimal performance. Q: Does my computer support dual-channel memory? A: No. Your system does not support dual channel. Q: Does my computer support ECC memory? A: No. Your system does not support ECC. Because ECC and non-ECC modules should not be mixed within a system, install the same type of modules that are already in your system. (idk if u needed to no any of that..)(i got that info from another question i asked but noone else was posting on it so i trying again) thanks again john- i dont have the money for a new computer im trying to make do with what i got for now by putting a little money in this one. Best answer for computer ram pricing help?:
Answer by John
honestly if your computer is 6 years old then in my opinion your best bet would be just to go out and get a new computer. It would same so much time with all these questions. Plus computers are truly outdated right when they come off the shelves so if you computer is 6 years old then if you don't already, you will soon start having compatibility problems with the latest software sense 2 windows versions have came out since then. you can get a new laptop or notebook for about $ 700-900 and you wouldn't have to worry about anything for another 6 years.

How to configure a router
Original version by Lukasz Sawicki
Proper configuration of the router is the precondition for networking and Internet access. Let's begin with the description of its functions. In general, router is a network device that is a communication node between the sending and receiving endpoint. The control of the traffic is called routing. Router creates a routing table or routing information base (RIB) that stores the best routes to certain network destinations, or the "routing metrics" associated with those routes, and the path to the next hop router. It allows to direct the packets to specified destinations. The routing process means interaction of at least two subnets.
The immense growth of the number of Internet users is the reason of remedial measures that overcome the limits of Ipv4 (Internet Protocol version 4). One of the measures is routing. It means linking of internal network with a pool of "private" IP addresses to the public network. Simply the router uses less (external) IP addresses than the number of supported computers in the local network. The diagram below depicts the typical solution.
Example of routing with NAT function
Router configuration example is based on the
TP-Link TL-WR542G device
Notice: TP-Link TL-WR542G N2950 does not support ADSL service (it is not equipped with ADSL modem).
Router connects two or more logical subnets, e.g. external network with Internet access (WAN) with local network (LAN), making a bridge for information exchange. Without proper configuration the connection will be impossible. In most cases, router acts as a specialized computer (replacing a standard computer) working in external network, with software and hardware tailored to the tasks of routing and forwarding. It allows to create internal (local) network.
In this case, the computer configuration involves:
taking down all settings of the NIC (working in external network),
IP address
Subnet mask
Default gateway
Preferred DNS server
changing the way of address assignment to dynamic (DHCP), or setting fixed IP address from the router's range,
connecting the computer with LAN port of the router.
Example of assigning a fixed IP address for TCP/IP protocol. This option is used when the router does not assign addresses automatically. At this stage there is no need to enter default gateway nor DNS servers parameters.
After restarting the computer, there is possibility of connecting with the router (via Internet browser). The logged in user (the initial user name and password are given in the user's manual) can configure the router.
The login window
The easiest way of configuring the router is use of "Quick Setup" option.
The first dialog box
To begin configuration we should choose Next.
It is important to select adequate kind of WAN connection type:
There are three possibilities:
PPPoE - in the case of network using PPPoE protocol (rather untypical),
Dynamic IP - the router will get IP address automatically (the most common option),
Static IP - in the case of fixed IP address.
Choice of WAN connection type
For Static IP option there are needed the settings of the NIC (to be entered). In the case of Dynamic IP this box will be omitted:
In this box there are entered adequate settings (previously taken down or given by the ISP)
After configuring WAN port parameters the next step is setup of Access Point:
Planning to use access point, it is needed:
to select suitable channel,
to set SSID,
to choose the region (country),
to set data encryption and cryptographic keys (in the tab Wireless >> Wireless Settings).
