Cable Operator

Errors can be categorized as a single-bit error or burst error. A single bit error has one bit error per data unit. A burst error has two or more bits errors per data unit.

a. Physical Layer

b. Data Link Layer

c. Network Layer

d. Transport Layer

e. Session Layer

f. Presentation Layer

g. Application Layer

i) Broadcast and

ii) point-to-point

C RC appends a sequence of redundant bits derived from binary division to the data unit. The divisor in the CRC generator is often represented as an algebraic polynomial.

Any candidate can read and regurgitate the company’s “About” page. So, when interviewers ask this, they aren't necessarily trying to gauge whether you understand the mission—they want to know whether you care about it. Start with one line that shows you understand the company's goals, using a couple key words and phrases from the website, but then go on to make it personal. Say, “I’m personally drawn to this mission because…” or “I really believe in this approach because…” and share a personal example or two.

In a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously.

It is the method used to solve the channel allocation problem .It is used for:

i) ground based radio broadcasting

ii) In a network in which uncoordinated users are competing for the use of single channel.

It is of two types:

1. Pure aloha

2. Slotted aloha

It is possible that a switch receives packets faster than the shared link can accommodate and stores in its memory, for an extended period of time, then the switch will eventually run out of buffer space, and some packets will have to be dropped and in this state is said to congested state.

This reveals whether candidates are staying up on trends. Do they have a sincere interest in IT and keep up on changes in the field and your industry?

Everyone deals with professional disappointment at some point. What you want to know is how people handle these situations. The best candidates will use setbacks as springboards toward positive changes, such as getting a certification that will help position themselves for advancement next time there’s an opportunity.

In networking and in other areas, a task is often begun before the previous task has ended. This is known as pipelining.

It is a serial mode of transmission.In this mode of transmission, bits are sent in a continuous stream without start and stop bit and without gaps between bytes. Regrouping the bits into meaningful bytes is the responsibility of the receiver.

A network is a set of devices connected by physical media links. A network is recursively is a connection of two or more nodes by a physical link or two or more networks connected by one or more nodes.

Seemingly random personality-test type questions like these come up in interviews generally because hiring managers want to see how you can think on your feet. There's no wrong answer here, but you'll immediately gain bonus points if your answer helps you share your strengths or personality or connect with the hiring manager. Pro tip: Come up with a stalling tactic to buy yourself some thinking time, such as saying, “Now, that is a great question. I think I would have to say… ”

If you were unemployed for a period of time, be direct and to the point about what you’ve been up to (and hopefully, that’s a litany of impressive volunteer and other mind-enriching activities, like blogging or taking classes). Then, steer the conversation toward how you will do the job and contribute to the organization: “I decided to take a break at the time, but today I’m ready to contribute to this organization in the following ways.”

Along similar lines, the interviewer wants to uncover whether this position is really in line with your ultimate career goals. While “an NBA star” might get you a few laughs, a better bet is to talk about your goals and ambitions—and why this job will get you closer to them.

Nothing says “hire me” better than a track record of achieving amazing results in past jobs, so don't be shy when answering this interview question! A great way to do so is by using the S-T-A-R method: Set up the situation and the task that you were required to complete to provide the interviewer with background context (e.g., “In my last job as a junior analyst, it was my role to manage the invoicing process”), but spend the bulk of your time describing what you actually did (the action) and what you achieved (the result). For example, “In one month, I streamlined the process, which saved my group 10 man-hours each month and reduced errors on invoices by 25%.”

To reduce the possibility of collision CSMA method was developed. In CSMA each station first listen to the medium (Or check the state of the medium) before sending. It can’t eliminate collision.

This interview question seems forward (not to mention intimidating!), but if you're asked it, you're in luck: There's no better setup for you to sell yourself and your skills to the hiring manager. Your job here is to craft an answer that covers three things: that you can not only do the work, you can deliver great results; that you'll really fit in with the team and culture; and that you'd be a better hire than any of the other candidates.

b. Type of transmission medium
