Web development is a broad term for any activities related to developing a web site for the World Wide Web or an intranet.
This can include e-commerce business development, web design, web content development, client-side/server-side coding, and web server configuration.
However, among web professionals, "web development" usually refers only to the non-design aspects of building web sites, e.g. writing markup and coding.
Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, or social network services.
For larger businesses and organizations, web development teams can consist of hundreds of people (web developers).
maller organizations may only require a single permanent or contracting webmaster, or secondary assignment to related job positions such as a graphic designer and/or Information systems technician.
Web development may be a collaborative effort between departments rather than the domain of a designated department.

Firewall

Merupakan suatu aplikasi @ perisian yang mengawal in & out bound (apa saja yg masuk dr network card) network traffic

• menapis in / out dlm network
• pengawal traffic (allow & block)
• bukan antivirus
• cth firewall (COMODO -> rules allow + block)

Keperluan pada pc :

• utk kawal in & out bound yg berlaku dlm network card
• control sebarang komunikasi atr pc dgn pc yg lain / host lain drpd network card.
• hanya menggunakan rules
  
  • 1. allow + deny
    
  • 2. accept + firewall
  • 3. allow + block

* Setiap komunikasi yang berlaku menggunakan IP + Port
Port
80 - http
8080 - proxy
21 - ftp
53 - DNS
110 - POPS
22 - ssh (hacker selalu guna)
20 - telnet

* Reason guna firewall Staff & student :

• tidak benarkan mana-mana pihak boleh control server
• Kalau student & staf boleh control server maka tiada fungsi Chief Network Server

* PC standalone tidak boleh control PC lain untuk block kerana ia bukan server (iaitu PC yg lain2 tidak connect pada PC tersebut)


A firewall is a dedicated appliance, or software running on another computer, which inspects network traffic passing through it, and denies or permits passage based on a set of rules.
