For information to show on-screen on a PC from an internet based application, there are various processes that must be run through.
First of all you would need to have the application/program to run the internet such as Internet Explorer or Google Chrome, Mozilla Firefox, Safari, etc... Next there needs to be a connection to the internet via router or hub which deals with the wireless or fiber optic connection depending on your ISP's (Internet Service Provider) method - The ISP is a company like Virgin, BT and others that provide a connection. You would then have to insert into the address bar of your application (in this case i'll use Internet Explorer) and type a domain name which is essential for getting the information that you want. The domain name works as a IP address to connect to and this domain/website will send information to your computer screen in the form of 'packets' which can be all forms of text, audio and images including links. These packets are sent to your computer through the ISP, the router and then to your computer which is linked to your IP.
Cloud Computing
Cloud computing is the means of connecting through a network or service with a handheld device, portable desktop or any other kind of technology that connects through the use of apps/applications to the internet that allows the storage of data online..
- TCP
- IP
- HTTP
- SSL
Online Applications
Online applications are internet based applications that require no download or install to your computer. These consist of flash games, wikipedia, 9gag, google search, etc...
- Can range from all of the protocols below
Blogs
These are sites that contain information published by the user. The 'posts' are what the blogger would publish to be seen by whoever the audience is set - this includes sites like twitter and facebook.
- TCP
- IP
- HTTP
- SSL (for passwords and the like)
- MIME
Web 2.0
Web 2.0 is the term used which involves the change in the internet and how webpages changed from still HTML pages to more interesting and active webpages which enabled the sharing of information and files online. This involved blogs, and online applications like posterous and soundcloud.
- Can range from all of the protocols below
D1
Here's the link to a website that I used explains each of the TCP/IP protocols in a comprehensible amount of detail. http://www.w3schools.com/tcpip/tcpip_protocols.asp
TCP - Transmission Control Protocol
TCP is used for transmission of data from an application to the network.
TCP is responsible for breaking data down into IP packets before they are sent, and for assembling the packets when they arrive.
IP - Internet Protocol
IP takes care of the communication with other computers.
IP is responsible for the sending and receiving data packets over the Internet.
HTTP - Hyper Text Transfer Protocol
HTTP takes care of the communication between a web server and a web browser.
HTTP is used for sending requests from a web client (a browser) to a web server, returning web content (web pages) from the server back to the client.
HTTPS - Secure HTTP
HTTPS takes care of secure communication between a web server and a web browser.
HTTPS typically handles credit card transactions and other sensitive data.
SSL - Secure Sockets Layer
The SSL protocol is used for encryption of data for secure data transmission.
SMTP - Simple Mail Transfer Protocol
SMTP is used for transmission of e-mails.
MIME - Multi-purpose Internet Mail Extensions
The MIME protocol lets SMTP transmit multimedia files including voice, audio, and binary data across TCP/IP networks.
IMAP - Internet Message Access Protocol
IMAP is used for storing and retrieving e-mails.
POP - Post Office Protocol
POP is used for downloading e-mails from an e-mail server to a personal computer.
FTP - File Transfer Protocol
FTP takes care of transmission of files between computers.
NTP - Network Time Protocol
NTP is used to synchronize the time (the clock) between computers.
DHCP - Dynamic Host Configuration Protocol
DHCP is used for allocation of dynamic IP addresses to computers in a network.
SNMP - Simple Network Management Protocol
SNMP is used for administration of computer networks.
LDAP - Lightweight Directory Access Protocol
LDAP is used for collecting information about users and e-mail addresses from the internet.
ICMP - Internet Control Message Protocol
ICMP takes care of error-handling in the network.
ARP - Address Resolution Protocol
ARP is used by IP to find the hardware address of a computer network card based on the IP address.
RARP - Reverse Address Resolution Protocol
RARP is used by IP to find the IP address based on the hardware address of a computer network card.
BOOTP - Boot Protocol
BOOTP is used for booting (starting) computers from the network.
PPTP - Point to Point Tunneling Protocol
PPTP is used for setting up a connection (tunnel) between private networks.
Your explanation for P1 is fine, but the flow diagram is meaningless.
ReplyDeleteFor m1 you need to go into more detail and explain all of the points in italics.
For D1 you need to read the task again.
Nearly there, but your explanation of cloud computing is not actually correct.
ReplyDeleteA hyperlink is not what we are after for a distinction task.
It is all good now. Well done.
