In this all computers are connected using a central hub.

Advantages: Can be inexpensive, easy to install and reconfigure and easy to trouble shoot physical problems.

TELNET is a client –server application that allows a user to log on to a remote machine,giving the user access to the remote system. TELNET is an abbreviation of terminal Network.

Data link layer is responsible for carrying packets from one hop (computer or router) to the next. The duties of data link layer include packetizing, adderssing, error control, flow control, medium access control.

Packet filter is a standard router equipped with some extra functionality. The extra functionality allows every incoming or outgoing packet to be inspected. Packets meeting some criterion are forwarded normally. Those that fail the test are dropped.

Server-based network: provide centralized control of network resources and rely on server computers to provide security and network administration

Peer-to-peer network: computers can act as both servers sharing resources and as clients using the resources.

It is the main protocol used to access data on the World Wide Web .the protol transfers data in the form of plain text,hypertext,audio,video,and so on. It is so called because its efficiency allows its use in a hypertext environment where there are rapid jumps from one document to another.

In client server model ,the client runs a program to request a service and the server runs a program to provide the service.These two programs communicate with each other. One server program can provide services to many client programs.

1,000? 10,000? 100,000? Seriously?

Well, seriously, you might get asked brainteaser questions like these, especially in quantitative jobs. But remember that the interviewer doesn’t necessarily want an exact number—he wants to make sure that you understand what’s being asked of you, and that you can set into motion a systematic and logical way to respond. So, just take a deep breath, and start thinking through the math. (Yes, it’s OK to ask for a pen and paper!)

Network control protocol is a set of protocols to allow the encapsulation of data coming from network layer protocol that requires the services of PPP

A node that is connected to two or more networks is commonly called as router or Gateway. It generally forwards message from one network to another.

It is a serial mode of transmission.

In this mode of transmission, each byte is framed with a start bit and a stop bit. There may be a variable length gap between each byte.

The process that allows a network to self-repair networks problems. The stations on the network notify the other stations on the ring when they are not receiving the transmissions. Beaconing is used in Token ring and FDDI networks.

The best managers are strong but flexible, and that's exactly what you want to show off in your answer. (Think something like, “While every situation and every team member requires a bit of a different strategy, I tend to approach my employee relationships as a coach...”) Then, share a couple of your best managerial moments, like when you grew your team from five to 15 or coached an underperforming employee to become the company's top salesperson.

This question can clue you in to personality characteristics or qualities that may not be apparent through the resume or traditional interview questions.

Start by explaining what you'd need to do to get ramped up. What information would you need? What parts of the company would you need to familiarize yourself with? What other employees would you want to sit down with? Next, choose a couple of areas where you think you can make meaningful contributions right away. (e.g., “I think a great starter project would be diving into your email marketing campaigns and setting up a tracking system for them.”) Sure, if you get the job, you (or your new employer) might decide there’s a better starting place, but having an answer prepared will show the interviewer where you can add immediate impact—and that you’re excited to get started.

The address resolution protocol (ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver.

The reverse address resolution protocol (RARP) allows a host to discover its Internet address when it knows only its physical address.

The #1 rule of answering this question is doing your research on what you should be paid by using sites like Payscale and Glassdoor. You’ll likely come up with a range, and we recommend stating the highest number in that range that applies, based on your experience, education, and skills. Then, make sure the hiring manager knows that you're flexible. You're communicating that you know your skills are valuable, but that you want the job and are willing to negotiate.

Depending on what's more important for the the role, you'll want to choose an example that showcases your project management skills (spearheading a project from end to end, juggling multiple moving parts) or one that shows your ability to confidently and effectively rally a team. And remember: “The best stories include enough detail to be believable and memorable,” says Skillings. “Show how you were a leader in this situation and how it represents your overall leadership experience and potential.”

What your interviewer is really trying to do with this question—beyond identifying any major red flags—is to gauge your self-awareness and honesty. So, “I can't meet a deadline to save my life” is not an option—but neither is “Nothing! I'm perfect!” Strike a balance by thinking of something that you struggle with but that you’re working to improve. For example, maybe you’ve never been strong at public speaking, but you've recently volunteered to run meetings to help you be more comfortable when addressing a crowd.
