WEB BROWSER & SEARCH ENGINE

Assalamu’alaikum..peace yow..hehe!!

Hello, guys! How are you all doing? Is everything okey?hehe..^^

In this post, I will share with you guys about the topic that Mr. Abdul Razak Idris has taught me in our sixth class. All right, guys?..teehee..^^

In this class, we learned about Internet Browser or Web Browser and also about the search engine.  The two most popular browsers are Mozilla Firefox and Microsoft Internet Explorer .Both of them are graphical browsers, which means that they display graphics as well as text. Click here to know more about the browsers….>.<

Then we learned about the search engines. 

The functions of a search engine are;

·        To browse web pages that we are looking for

·        To search the web.

·        To view and interact with various types of resources available on the World Wide Web(WWW)

·        To provide a way to look at and interact with all the information on the WWW

And do you want to know how do search engines work?...click here to find out..hehe..:)


Or you can watch this if you are too lazy to read...XD

There are lots of examples of search engine that could help us to find the information that we want such as Yahoo, Google, Bing, etc….

Some of the search engines in the world…..

There are three types of search tools that we have learned in our class. They are: -

1)  Search Engine

2)  Directories

3)  Meta-search engine

Search engine is the most basic ways that we use to find anything. Any web page that contains the title that we wrote will appear in just less than 1 second. Search engine use spiders whose actions are very fast.

If we want to make the search engine find the information that we want in specific ways, we could use directories. Using directories, we could specific the title, the format of the document or information, the time and etc. One of the examples of directories is Google Advanced Search.

Meta-search engine will include several search engines when they try to find the information that we want.


I think that's all for now..thanks for reading...see ya..>_<

Internet Service Provider (ISP)

Assalamu’alaikum..hye there..how are you today?.. How is life?..teehee..

Now, I want to share with you guys about the INTERNET, that I learned in my fifth class.

Do you know what is the meaning of internet? Well, the internet is a global network connecting millions of computers using a common set of TCP/IP.  

Internet started with only four interconnected computers in 1969 and was known as ARPANET. The Advanced Research Project Agency (ARPA) submitted the proposal for the project on June 3, 1968 which was approved a few weeks later. This proposal entitled “Resource Sharing Computer Networks” would allow ARPA not only further sharing of their data but would allow them to further their research in a wide variety of military and scientific fields. After being tested in four locations, the network spread and the new protocols created for its use evolved into today’s World Wide Network. 

The interneeettt!!!!!!...

Then, we learn about internet infrastructure. The hierarchy of networks are:

• ·         From a single computer to LAN
• ·         From LAN to ISP
• ·         ISP to WWW

In order to connect yourself to the internet, you just need a computer, web browser and internet access. However, the policy and procedures involves to bring you on the internet is quite complicated.

Then, we learned about Internet Service Provider (ISP). ISP or also called as IAP(Internet Access Provider) is a company that provides access to the internet. For a monthly fee, the service provider gives you a software package, username, password and access phone number. ISPs themselves are connected one another through Network Access Points (NAPs). In Malaysia, the most popular ISP is TMNet.

Here are some of the ISP in Malaysia, if  you want to know...^^

Guys, for your information,,the internet can be access via dial-up, landline, t-lines, satellite, cell phones and etc.

Then, we learned about Internet Protocol or IP. According to what Mr. Razak said in our class, every machine has their own IP address. IP is a language that computers use to connect with each other. An IP address serves two principal functions:

 host or network interface identification and location addressing

Do you know what your computer’s IP is? The IP for my desktop that I used in Mr. Razak’s class is 161.139.220.01..161 refers to UTM, 139 refers to the Faculty of Education and the rest refers to the desktop…it is interesting, isn’t it?..haha..:D

See you in the next post..bye..assalam..>.<

the fourth..:)

Assalamu’alaikum…

Hello, guys..whazzup..hehe..^^

Just like my previous post, I wanna share with you guys a topic that I’ve learned after cabling which is WIRELESS.

As we all know, wireless means without wire. For deeper meaning, wireless networking technologies range from global voice and data networks which allow user networks, to establish wireless connections across long distances, to infrared light and radio frequency technologies that are optimized for short‐range wireless connections.

Wireless network most commonly use to refer to a telecommunications network whose interconnections between nodes is implemented without the use of wires, such as a computer network.

Do you want to know more about wireless? Click here…

Here are some of the examples

Wireless communication involves:-

• Radio frequency communication

• Microwave communication, for example long‐range line of sight via highly directional antennas or short line‐of‐antennas, short range communication

• Infrared (IR) short‐range communication, e.g. from remote controls or via IRDA

Applications may involve point‐to‐point communication, point‐to‐multipoint communication, broadcasting, cellular networks and other wireless networks.

Type of Wireless Network

·         Wireless wide area networks (WWANs)

·         Wireless metropolitan area networks (WMANs)

·         Wireless local area networks (WLANs)

·         Wireless personal area networks (WPANs)

Application

• Voice and messaging,

• Hand‐held and other Internet‐enabled devices, and

• Data Networking.

11)   Voice and messaging,

·         Cell phones, pagers.

·         analog or digital standards

– The analog standard is the Advanced Mobile Phone Service (AMPS).

– Digital standards are Global System for Mobile Communications (GSM), Time Division Multiple Access (TDMA), or Code Division Multiple Access (CDMA).

22)   Hand‐held and other Internet‐enabled devices

• Internet‐enabled cell phones and Personal Digital Assistants (PDAs) can connect to the Internet across a digital wireless network

• Uses Wireless Application Protocol (WAP), and WML (Wireless Markup Language)

33)   Data Networking.

·         Infra Red

·         wireless local area networks (WLANs)

·         Broadband wireless.

·         Bluetooth

·         WiMax

Another example of a wireless network setup

 Cellular systems

• 0G, 1G, 2G, 3G, 4G.

• 1G

1G is short for first‐generation wireless telephone technology. This generation of phones and networks is represented by the brick‐sized analog phones introduced in the 1980’s. Subsequent numbers refer to newer and upcoming technology.

 

• 2G

2G phones use digital networks. Going all‐digital allowed for the introduction of digital data services, such as SMS and email. 2G networks and their digital nature also made it more difficult to eavesdrop on mobile phone calls.

• 3G

3G networks are an in between standard. 3G is seen more as pre4G instead of a standard of its own. The advantage 3G networks have over 2G networks is speed. 3G networks are built to handle the needs of today’s wireless users. This standard of wireless networks increases the speed of internet browsing, picture and video messaging, and handheld GPS use.

• 4G

4G (AKA Beyond 3G) is like the other generations in that its advantage lies in promised increased speeds in data transmission. There is currently no formal definition for 4G, but there are objectives. One of these objectives is for 4G to become a fully IP‐based system, much like modern computer networks. The supposed speeds for 4G will be between 100 M bit/s and 1 G bit/s.
