How do you make window xp sp3 share wireless wpa2 computer to computer or phone network?
I'm using window-xp, (sp3), i know how to make an adhoc network, and I'm using it now, i even know how to share internet in window xp among two computers(using adhoc), I've been searching for this all over the internet, and never find an answer to share wpa2 in window xp, my computer is able to connect to wpa2 but this is not what i want, i want the pc to share the wpa2, because my phone is not supported adhoc, but only wpa2 and other wifi,, connectify doesn't work, if there's a way to make my window xp share (wpa2) wireless, it would be a wish for me to know it ,, i want to download some app in my phone, but it can't connect to adhoc,, so is there a way to make my xp share wpa2 wireless?
How do email service provider websites earn money?
Advertising, of course! Even this site obtains some of its funding from advertisers. While some of them provide random topics, the more sophisticated ones actually 'read' your email and put related advertising beside the mail. If you talk to someone about finding genealogy links, advertising related to family tree products will show. Or talk about karate and martial arts links will arrive.
There are 250 2-address instructions. There are only a total of 256 2-address instructions allowed if we have 32-bit instructions (two addresses take up 24 bits, leaving only 8 bits for the opcode). Looking at the 8 bit opcode, assume bit patterns 00000000 (0) through 11111001 (249) are used for the 250 two-address instructions. Then there are 6 bit patterns left for one address instructions. However, each one of these can use the remaining 12 bits gained from having only one operand, so we have 6 * 212. 00000000 11111001 11111010 11111010 ... 11111111 11111111 ______________________________________________________________________________ xxxxxxxxxxxx xxxxxxxxxxxx 000000000000 111111111111 000000000000 xxxxxxxxxxxx 111111111111 xxxxxxxxxxxx xxxxxxxxxxxx xxxxxxxxxxxx xxxxxxxxxxxx xxxxxxxxxxxx 250 2-address instructions 212 212 6 * 212 1-address instructions

What jobs have been replaced by computers?
Jobs working in factories are quickly becoming "robotized" as robots have the ability to work faster and more efficiently than humans. The near future will show that robots will take the mediocre jobs that involve just putting things together and dissassembly.

P.S. work hard in school, robots wont be lawyers or doctors in the near future :)
What are the different types of computer backups?
A copy backup copies all the files you select, but does not mark each file as having been backed up (in other words, the archive attribute is not cleared). Copying is useful if you want to back up files between normal and incremental backups because copying does not affect these other backup operations.
Daily backupA daily backup copies all the files that you select that have been modified on the day the daily backup is performed. The backed-up files are not marked as having been backed up (in other words, the archive attribute is not cleared).
Differential backupA differential backup copies files that have been created or changed since the last normal or incremental backup. It does not mark files as having been backed up (in other words, the archive attribute is not cleared). If you are performing a combination of normal and differential backups, restoring files and folders requires that you have the last normal as well as the last differential backup.
Incremental backupAn incremental backup backs up only those files that have been created or changed since the last normal or incremental backup. It marks files as having been backed up (in other words, the archive attribute is cleared). If you use a combination of normal and incremental backups, you will need to have the last normal backup set as well as all incremental backup sets to restore your data.
Normal backupA normal backup copies all the files you select and marks each file as having been backed up (in other words, the archive attribute is cleared). With normal backups, you only need the most recent copy of the backup file or tape to restore all of the files. You usually perform a normal backup the first time you create a backup set.How do you find the ip address for notdoppler.com?

SIP (Session Initiation Protocol) is generically broken down into two components, the UAC (User Agent Client) and the UAS (User Agent Server).
A SIP client can range from an endpoint such as a phone to a software application on a PC or mobile device that speaks SIP with the server. The client is capable of initiating, receiving, and terminating SIP sessions.
Bear in mind that SIP is only signaling, it is not the actual voice traffic. RTP (Real-time Transport Protocol) or SRTP (Secure Real-time Transport Protocol) is used to carry the voice data. SIP's purpose is to establish, maintain, and terminate a VoIP call.
In essence, a DNS server is simply a database that links meaningful names (known as host names), such as http://www.microsoft.com, to a specific IP address, such as 192.168.124.1. So pretty much DNS or the Domain Name System are the guys who know everyone by their real name, so when you type in a 'nickname' (host name) eg: Yahoo.com in your address bar, they say 'oh you mean 209.191.122.70' and your computer now knows who you need to message. Also, on Windows you have something called a Windows Host File - your own little database similar to this so you don't always have to go through the DNS.
The DNS has a little more function than this but this is its main use. Also it sometimes is not as simple as contacting one DNS server and getting IP right off. You may type in mail.yahoo.com and the first DNS server contacted says 'oh well I only know yahoo.com' so he sends you to another DNS server, perhaps yahoos DNS server, this is where you find out IP for mail.yahoo.com. This is why sometimes you will go to a page and it may take a second, this is because it may have to go through multiple DNS servers before someone knows who you're talking about.
As for DHCP, according to TCP/IP every client (your computer, your phone, etc, anything on a network) has to have a unique IP address and subnet mask. At one point in time, people had to do this manually - and considering you cannot have duplicates, it would be very strenuous and a pain to do. That's where DHCP comes in. DHCP does all this automatically. Each client gets a unique IP address, subnet mask, and other IP information such as default gateways and the IP addresses of WINS (Windows Internet Name Service) and DNS (Domain Name System) servers. DHCP makes certain that no clients have duplicate addresses, and this entire process is invisible to network administrators and network users.
Can you connect a wireless router to a wireless DSL modem?
I set up Peplink at work and it works great combining multiple internet sources.
From there site:
Increase your bandwidth at anytime. Peplink Balance multi-WAN routers give you the ability to transparently connect new low-cost Internet links, such as DSL, Cable, 3G Wireless to your existing network. Giving you a highly reliable, fast Internet.
Network traffic is distributed to different Internet links to achieve an overall increase of network speed.

What can verify TCP IP is installed?
TCP/IP can be verified as installed and operating by using the 'ping' command against the localhost address:
ping 127.0.0.1
or
ping localhost

Is an oil pipeline simplex half-duplex or full-duplex and why?
An oil pipeline would be classified as SIMPLEX, because the oil flows in only one direction.
Theoretically, I suppose it also could be half-duplex (flows in only one direction at a time, but can change direction). However, it would be very impractical to switch the direction of flow (but not impossible).
What function does the tcp protocol perform for a network connection?
it formats messages in segments
it reassembles messages at the destination
it creates a virtual circut between end user applications
How does a wireless network signal travel?
A wireless network signal travels through the use of radio waves. It is capable of travelling great distances in the open or shorter distances when penetrating walls and objects.
