Answer:
a. 1 is a packet, 2 is data, 3 is a frame.
Explanation:
And what is not mentioned is segment which used TCP/UDP and is part of Transport layer. The packet carries the destination and sender IP address, and is part of the Network Layer. The frame has the Mac address of destination device and senders device and is part of data link layer.
Hence segment has no IP address, hence b. is not correct. Also, data cannot have the IP Address, and Frame has the MAC address, Hence, the above answer. And this arrangement is part of Data Encapsulation.
Also keep in mind data can be anything like a series of bits, or any and it can or not have a header.
Answer:
A proactive computer professional will anticipate future problems and need
Explanation:
This statement is not only true for technology but for any field. Anybody who is proactive will always look for future, will foresee future problems and challenges and get ready to face those. He will simultaneously analyze the present interest and problems and connect the future and prepare himself well to be successful in the future.
For pro-active person’s success is not an end, even after getting succeeded he must work for tomorrow. So thus, the choice is justified with various analytical statement.
<h2>Upgrading and retraining are mandatory to move along with the world.</h2>
Explanation:
Let us understand the term deeply,
Upgrading - Updating yourself with the latest
Retraining - learning new skills
Let me give you a real-life example which is nothing but "mobiles". If you are not updated then:
- you will sit with mobile to make calls and
- do money transactions only by stepping into the bank,
- connect with people only through calls or directly visiting them,
- distance break up the relationship,
- booking tickets in classical way, etc.
These could be done in one touch if you have latest mobile with necessary applications.
In a similar way, we need to get retrained to get to learn new skills, technologies so that we can do our job the best, to be on track, be productive, convert your valuable knowledge in terms of money, to be peaceful in day today transactions, etc.
In any electrical installation, some current will flow through the protective ground conductor to ground. This is usually called leakage current. Leakage current most commonly flows in the insulation surrounding conductors and in the filters protecting electronic equipment around the home or office. So what's the problem? On circuits protected by GFCIs (Ground Fault Current Interrupters), leakage current can cause unnecessary and intermittent tripping. In extreme cases, it can cause a rise in voltage on accessible conductive parts.
