HTML: I've Gotta Admit I Thought This Was HoTMaiL

What is HTML?

HTML stands for Hyper-Text Mark-Up Language and is the authoring language used to create documents on the World Wide Web.

Pros:

1: If done right, applications developed this way are very responsive you have a clear separation of logic (on the server) and presentation (on the client); the server doesn't have to concern itself at all with the presentational aspects of the application.

2: Potentially more efficient use of network bandwidth (you are only sending raw data, no presentational boilerplate).

3: Easier to develop desktop-like GUIs, since you're less dependent on the request/response paradigm.

Cons:

1: You have to write your client code in Javascript, or a language that can compile to Javascript, because that's the only thing available in a browser resource usage on the client may be higher, so the application may not work well on substandard devices (think mobile browsers etc.).

2: It won't work at all with javascript disabled; if it is have a public-facing website, you have to think hard whether you are willing to take this risk (especially if you consider SEO and accessibility - a javascript-heavy approach is usually devastating on these two fronts).

3: A lot of logic has to be written twice: once on the client, and once again on the server (because you can never trust the client).

4: Concurrency can be a hell, so you need to design your client-side code very carefully and be prepared for all sorts of concurrency issues.

CSS: What kind of Sorcery is this?

CSS stands for Cascading Style Sheet and is used commonly in making a website

Pros:

1: Cross-Browser Functionality

 2: Speedy Development

4: Consistency

5: Reduce page size

6: Clean, Symmetrical Layouts

Cons:

1: Extra Code

2: Lack of Freedom

3: Forced Semantic Changes

4: Closing Thoughts

Protocols: Just like the Government

A protocol is a set of rules that governs the communications between computers on a network.

Kinds of Protocols:

POP : It stands for Post Office Protocol. It helps in receiving mails. It is mainly used for electronic mails.

SMTP : It stands for Simple Mail Transfer Protocol. It helps in sending mails. It is mainly used for email transmission across IP (Internet Protocol) based network.

DHCP : It stands for Dynamic Host Configuration Protocol. It helps in assigning automatic IP address to a computer via DHCP server.

ARP : It stands for Address resolution Protocol. It helps in resolving the IP address of the computer over a network. It works with IP address associated with the MAC (Media Access Control) address encrypted in NIC (Network Interface Card)

RDP : It stands for Remote Desktop Protocol. It helps in communication of remote desktop connection. It provides the user to access a system from other system in GUI (Graphical User Interface) mode over an IP based network.  

FTP : It stands for File Transfer Protocol. It is a standard network based protocol which is used to transfer files or to copy data from one host to the other host on TCP/IP base network.

TCP : It stands for Transmission Control Protocol. It is a connection oriented protocol and helps in packets data flow control and error recovery. It also helps in making a physical connectivity between the computers.

UDP : It stands for User Datagram Protocol. This protocol works with IP (Internet Protocol) as it contains some packet datagram information. It provides checksum for the data integrity and port number for addressing.

HTTP : It stands for Hyper Text Transfer Protocol. It is mainly used for the data communication over internet. It helps in communicating between a client and a web based server. Its port number is 80.
