Answer Engines
It is the existence of powerful search engines which have made the web so useful. However, finding answers to questions via search engines is a lot less predictable than the older habit of looking up an encyclopaedia. For this reason, 'answer engines' were created. These are like online encyclopaedias which deliver only a few answers but are detailed, usually accurate and useful when you now what you are looking for. However there are other free services using a peer-to-peer approach. One of these is Wikipedia. If you are an expert in a field, you can submit an article others will check before it is added to the site. Wikipedia is available in over 0 languages. Because it is so open, sometimes material is not as reliable or authoritative as it should be, so it is wise to check before using it.QUESTIONS

1. Why might a printed encyclopaedia be considered more reliable than Wikipedia? In what way might it be less reliable?
In an encyclopaedia information is all factual because it is written by professionals, whereas Wikipedia can be written/edited by anyone. Wikipedia might be more reliable because facts are regularly updated and there is much more information.
2. Use Wikipedia to research the topics from this chapter
a) Internet Protocol
The Internet Protocol (IP) is the principal communications protocol used for relaying datagrams (also known as network packets) across an internetwork using the Internet Protocol Suite. Responsible for routing packets across network boundaries, it is the primary protocol that establishes the Internet.
b) Firewall
A firewall can either be software-based or hardware-based and is used to help keep a network secure. Its primary objective is to control the incoming and outgoing network traffic by analyzing the data packets and determining whether it should be allowed through or not, based on a predetermined rule set. A network's firewall builds a bridge between an internal network that is assumed to be secure and trusted, and another network, usually an external (inter)network, such as the Internet, that is not assumed to be secure and trusted.
c) Cookie
A cookie, also known as an HTTP cookie, web cookie, or browser cookie, is usually a small piece of data sent from a website and stored in a user's web browser while a user is browsing a website. When the user browses the same website in the future, the data stored in the cookie can be retrieved by the website to notify the website of the user's previous activity. Cookies were designed to be a reliable mechanism for websites to remember the state of the website or activity the user had taken in the past.
I believe that the information is mostly reliable from Wikipedia. But if I was doing a research task using Wikipedia I would use other websites to make sure that it is correct, since anyone can edit the information.
3. Use a search engine to find out about the same three topics. Which method is faster? Which gave the most information? Which method was more accurate?
Wikipedia was a faster method to get information. Both Wikipedia and a search engine gave the most information. The search engine was more accurate because anyone can edit Wikipedia.

Why might a printed encyclopaedia be considered more reliable than Wikipedia? In what way might it be less reliable?
A printed encyclopaedia may be considered to be a more reliable source of information as it contains information found by experts that can’t be altered by the general public. It may be less reliable in the sense that the information might be out-dated and can’t be re-updated without reprinting the book.
Use Wikipedia to research the topics from this chapter Write a paragraph on each, reporting on how reliable you believe the information is and why
a) Internet Protocol
IP is the main avenue of communication to send network packets across an internet network by using the ‘Internet Protocol Suite’. IP is responsible for sending the packets of information across boundaries between networks.
b) Firewall
The main aim of a firewall is to keep a network secure. It works by sorting through data packets and either allowing them through or not by checking if they meet the specified set of rules. A firewall for a network acts as a bridge between an internal network (intranet) to another network e.g. the Internet that is not secure and trusted.
c) Cookie
A cookie is also known as an HTTP cookie, web cookie or browser cookie. Cookies are small pieces of data sent from a website and kept in the users web browser while they are using the website. Cookies can be used to retrieve previous information from when you last visited that site, such as usernames and passwords.
Use a search engine to find out about the same three topics. Which method is faster? Which gave the most information? Which method was more accurate?
The faster method I found was by using a search engine, because for some of the topics further specification was needed in Wikipedia e.g. ‘cookie’. Wikipedia however, did give some of the most information and it was quite detailed. Using a search engine however, would probably be the more accurate avenue as it gives the user the opportunity to compare information from different trusted sites.

QUESTIONS
1.Why might a printed encyclopaedia be considered more reliable than Wikipedia? In what way might it be less reliable?
A written/printed encyclopaedia is considered to be more reliable as it is printed and cannot be changed while Wikipedia can be changed by anyone at any time, day or night.
2. Use Wikipedia to research the topics from this chapter
a) Internet Protocol
The Internet Protocol (IP) is the principal communications protocol used for relaying datagrams (also known as network packets) across an internetwork using the Internet Protocol Suite.

Cookies were designed to be a reliable mechanism for websites to remember the state of the website or activity the user had taken in the past. This can include clicking particular buttons, logging in, or a record of which pages were visited by the user even months or years ago
Write a paragraph on each, reporting on how reliable you believe the information is and why?
I believe that the information from Wikipedia is not as reliable as other websites as Wikipedia can be changed by the general public, which would result in the information being incorrect.
3. Use a search engine to find out about the same three topics. Which method is faster? Which gave the most information? Which method was more accurate?
Wikipedia may be quicker and easier to find and retrieve information as it is the first result that comes up but, if I was to use information from Wikipedia I would research other websites as well.

1. Why might a printed encyclopaedia be considered more reliable than
Wikipedia? In what way might it be less reliable?
A printed encyclopaedia might be considered more reliable than Wikipedia because Wikipedia is available online for anyone to change whereas an encyclopaedia is all factual as it is written my professionals. On the other hand Wikipedia could be more reliable that a printed encyclopaedia sometimes as it can be updated more often and quickly.
2. Use Wikipedia to research the topics from this chapter. Write a paragraph on each, reporting on how reliable you believe the information is and why?
a) Internet Protocol
The Internet Protocol is the principal communications protocol used for relaying datagrams across an internetwork using the Internet Protocol Suite. It is the primary protocol that establishes the Internet and is responsible for sending packets of information across boundaries.
b) Firewall
A firewall keeps a network secure on either a software base or a hardware base. For a network, a firewall acts as a bridge between an intranet to another network. Its main objective is to control the incoming and outgoing network traffic by analysing the data packets and determining whether it should be allowed through or not.
c) Cookie
A cookie is also known as an HTTP cookie, browser cookie or web cookie. They are a small piece of data sent from a website which is stored in a user’s web browser whilst browsing a website. When the user browses the same website in the future, the data stored in the cookie can be retrieved by the website to notify the website of the user's previous activity.
3. Use a search engine to find out about the same three topics. Which
method is faster? Which gave the most information? Which method was more
accurate?
I found that Wikipedia was a faster method than a search engine, on finding out about the same three topics, IP, Firewall and Cookie. However Wikipedia did give more information in detail but a search engine would have been more accurate as Wikipedia is open for anyone to edit.
