<u>Answer</u>: B. Identify the source of the active connection
<em>Any problem can be fixed only finding of the source of it. We can fix a problem in ‘n’ number of ways but it might again come back if source of it is not identified.</em>
<u>Explanation:</u>
Identify the source of the active connection is the NEXT step the team should take. It is very similar to our human body.
If the infection is coming in the body again and again and gets fixed in the treatment, the reason for come - back will be identified so that it does not <em>lead to unnecessary treatment. </em>
In a similar way, if source are identified then the problem of come-back can be avoided. <em>So option B would be the right choice.</em>
Answer: Network attached storage device
Explanation:
Network attached storage(NAS) is the data storage server device that is responsible for serving files to configuration and other components.Through this sever device data can be retrieved by various client and user from central disk capacity .It provides good data access to diverse user and client of data.
- Other options are incorrect because RAID drive, server station, gigabit NIC are not the devices that centrally store huge amount of data for access.
- Thus, the correct option is network attached storage(NAS) device
Answer:
In binary signaling, Non Return to Zero (NRZ) is the technique in which zero voltage is represented by 0 bit while high voltage is represented by 1 until the voltage level change from high to low.
Explanation:
There are different techniques to encode the signal for transmission between transmitter and receiver. These techniques includes return to zero, non return to zero. In return to zero technique, the if the voltage is high the signal will become 1 for half of the time period and then after half time period it return to 0.
In NRZ the signal is 0 if the voltage level is zero. In case of high voltage of the signal the binary bit remains 1 until the next zero voltage level arrive in the signal until the end of the time period of bit.
The complete question rather reads;
DRU is a small brokerage house that enables its clients to buy and sell
stocks over the Internet, as well as place traditional orders by phone or Fax. DRU has just decided to install a new e-mail package. One vendor offering an SMTP-based two-tier client-server architecture. The second vendor is offering a Web-based e-mail architecture. DRU doesn't understand either one but thanks the Web-based one should be better because, in their words, "the Web is the future".
<u>(a) Briefly explain to DRU management, in layperson's terms, the difference between the two.</u>
<u>(b) Outline the pros and cons of the two alternatives and </u>
<u>(c) Recommend to DRU about which is better</u>
<u>Explanation:</u>
a) SMTP stands for Simple Mail Transfer Protocol. Thus, put simply an SMTP-based two-tier client-server architecture is a package that involves using a client-server provider like Outlook. This implies that Outlook provides the client with his own unique PO Box (server) so to speak.
While the Web-based e-mail architecture enables the DRU access to online mail platforms like G-mail with little server customisation features.
b. The Web-based e-mail architecture is good for personal email activities because of its ease of operation, however, it does not provide top security and customisation features. While an SMTP-based two-tier client-server architecture allows for unique server customisation with added security features as well be suitable for larger organisational work. Although a disadvantage is that it may cost more and quite a complex process to learn.
c) Since DRU is a growing firm the SMTP-based two-tier client-server architecture would be recommended as this would provide it will efficient customer service delivery.
Personally I have my budget spreadsheet with all of my expenses in columns. Then I have a column showing my estimated paycheck (updating with actual# later). Then the formula in the "Remaining" column that I use is this: sum((A1:A99)-A100) Where A1 through A99 (or whatever# of expenses you have) and -A100 or whatever cell name your paycheck/money is entered into - and that's all I do. I actually have a 3 year budget, including birthdays, holidays, vacations, etc. so that you can plan ahead for any expenses and save away any extra.
