What are the advantages of using memory stick as a storage device?
The main advantage is that they allow you to transport files easily between computers. they are small and light and easy to carry around
The main disadvantage is that if they are stolen, sensitive files can be easily accessed.
How do you design a decimal counter using j-k flip-flop?
Since it is a 3 bit counter( max state here is 6<8 i.e. 2^3) so 3 FF would be used here.Name these three FF A, B,C (u can assume ny other name).
Prepare a state table- here we have 2 count from state 0 to 1, 1(001 in binary) to next state(010), then from 2(010) to 4(100) , then from 4(100) to 5(101), then from 5(101) to 6(110).
After u prepare the state table next step is to prepare the excitation table from this state table.Generally RS FF is used to design the sequence with even no. in the end, for odd we gen' use JK FF's.
Using the present state as o/p transitions, and the basic excitation table for rs ff prepare the table.( this can be done here like ABC changes value as 000 to 001 write the value for Ja as X and Ka as 0, same can be done for Jb , Kb, as well as Jc, Kc.)
Using excitation table prepare K-maps for Ja , Ka , Jb ,Kb , Jc , Kc .From these Kmaps obtain simplified Boolean expressions.
And these boolean expressions can be used to prepare complete Logic.
A host (also called a client) does this. The device that provides the information a host is looking for is called a server.
Any device connected to the network is called?
anything connect to a network is called a node's this can be your printer, laptop,what ever as long as it is there its a node
What is a purpose of default gateway?
When users sign into the internet they may not realize they are using a series of gateways to access their favorite websites. A default gateway is used a lot in office settings where a lot of computers need to be connected to both their internal network and the internet.
Can a wireless computer be tracked to a position while off?
No. If the power is off, then the network adapter cannot transmit. If no communication can be made with the wireless device, then no information can be obtained regarding its whereabouts.
Note that, in general, WiFi connections cannot be used determine the location of devices that they are connected with. With a 3G or GPRS ('mobile broadband') connection, such localisation is possible, but is technically extremely difficult for anyone but the user of the device in question.
What is difference between ATM and ISDN?
1-ISDN is a circuit switching where as ATM is a packet switching.
2-ISDN is a point to point fixed bandwidth where as ATM is a variable bandwidth.

Can you connect the Cricket wireless USB broadband to a wireless router?
The short answer is that you can bridge connections and all but its complicated and the way my cricket works you would not want to connect a router of any kind. The speed is slow enough that i would not connect more than one computer even if its possible. What a pessimistic answer. Answer:
The way it was made should tell you that it's NOT recommended and probably difficult or nearly impossible to use with a router! It uses XP's dial-up networking (or better known as RAS) to make a connection to the internet... since the router doesn't have RAS, the modem would have NO way to make a connection without a computer! So, in essence, the only way is to go through the computer first... then route the traffic to the router or use ICS on your network... either is not really recommended as this modem isn't really fast enough to support more than one computer, as mentioned. So you should heed the answer! If you are only connecting to one computer, then just use ICS (Internet Connection Sharing)... be sure to have good firewalls on BOTH computers! More than one computer using the internet connection is NOT recommended as performance will suffer greatly... it's also NOT recommended connection for gamers and people using p2p, etc. Look elsewhere if you are a heavy duty user! I connected it to wireless router. You make good points about it not being made for that purpose but it's not "nearly impossible" It was very simple. Yes you have to go through the computer first, but NO it doesn't make performance suffer. Cricket broadband isn't all that great performance wise PERIOD. But if you already have it you may as well get the same inconsistant service on ALL your comp. for the same price you were paying to have it on 1 comp. My house is filled with "v-idiot gamers" and"shySpace" users and we don't have any problems.

How does the network interface card work?
A network interface card (NIC) is a computer circuit board or card that is installed in a computer so that it can be connected to a network. Network interface cards provide a dedicated, full-time connection to the network.
Advantage and disadvantage of static routing?
A static IP address is where a computer keeps the same IP address every time it connects to the Internet. The advantage of a static IP is that you should not experience a lapse in Internet connection as you would do with a dynamic IP. A disadvantage of a static IP is that some websites only allow a certain amount of content to be downloaded. The user would have to change their IP address to be able to download more data.
