On which of the following frequencies does a Wi-Fi network work?  Correct Answer 5 GHz

  • Wi-Fi is the wireless network system most commonly used in the homes to connect multiple electronic devices through the internet. An instrument called a router is needed to connect the several instruments through the internet.
  • IEEE 802.11 specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN), Wi-Fi computer communication in various frequencies. 
  • WiFi uses radio frequencies to send signals between devices. 
  • WiFi works at a frequency of 2.4 GHz and 5 GHz.

You are the administrator of a Windows 2000 Server computer. The server contains one network adapter and is a file and print server for critical company resources. You install a second network adpater in the server and connect it to the same network subnet as the first adapter. You want to ensure that the first adapter is used for all network traffic and the second adapter is used only if the first adapter fails or is disconnected from the network. You also want to ensure that the server always has network connectivity even if one network adapter fails. What should you do?
Your network uses TCP/IP as the only network protocol. Devices on the network are configured to use IP address from the private 10.0.0.0 range. All the client computers on the network runs Windows 2000 Professional. The network includes Windows 2000 Server computers and UNIX servers. User's print jobs are sent to shared printers on a Windows 2000 Server computer named PrintServ that directs the print jobs to print devices attached directly to the network. You have a high-capacity print device that is attached to one of the UNIX servers. The UNIX computer uses the LPR printing protocol, and it's IP address is 10.1.1.99. The name of the printer queue is GIANT. You want users to be able to connect to this printer from their computers. What should you do?
Given below are two quantities named 1 and 2. Based on the given information, you have to determine the relationship between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity 1: P and Q can do a work in 6 days and Q and R can do a work in 60/7 days and P and R can do a work in 20/3 days. If Q and R work for first 2 days and left the work. Find the total time taken by P to complete the remaining work. Quantity 2: A and B can do a work in 8/3 days, B and C can do the same work in 3 days and A and C can do the same work in 24/5 days. In what time C alone can complete the work?

P can complete ¼ of some work in 10 days, Q can complete 40% of the same work in 48 days. R completes 1/8 of the work in 5 days and S does 1/10 of the work in 2 days. ½ of total work is done by (Q + R) and remaining work is done by (P + S). What will be the ratio of the days for completing ½ of work by (Q + R) and remaining work by the (P + S)?
The network uses TCP/IP as the only network protocol. You configure the remote access server on the network. Some users report that when they connect to the server they receive the following message |" IPX SPX compatible computer deported error 733" The EPP control network protocol for the network is not available. If the users allow the connection to continue they are able to connect to the services that use TCP/IP. You want to prevent this message from being displayed. What should you do?

A filter that passes all frequencies lying outside a certain range, while it attenuates all frequencies between the two designated frequencies is called?
Five men A, B, C, D and E can do a piece of work in 20, 10, 30, 40 and 50 days respectively. A, B, and C started the work and they work for 2 days after which A and B left the work and D joins the work. D and C work another 3 days together after which C leaves and E joins the work. Find in how many days E and D completed the rest of the work.
