Whoa..Hey all, call me Angah..this blog is created by the need of urgency of the assignment for this 2nd sem..so, I hope all of you can give support for me..feel free to follow & I will follow u back :)
The post title say 'awkward' , huh? Naaahh..i'm just goofing around about that 'awkward' thingy. There are nothing awkward happen when I update my blog, seriously.. That post title is just for grabbing readers attention..haha.
To be truth, I'm kind off addicted to this blog updating. Everyday, when I am at my room, I will check out my blog few times a day.
Updating blog for education purpose, I felt like a teacher that teach students new things...doesn't you feel the same way when you update something educational and useful to others? I'm keep wondering, what kind of teacher that I would be in the future? *wondering
This post is just for fun only, check my latest update on what is going on in my class, in my next post. See u guys later. Do rate and comment, ok peeps? :)
Hey, I'm back..now, the post is about our 3rd class for this course..I will tell you about Network Operating System ( NOS ) and also about the in-class presentation that we have to do on that day. Seriously, I do not expected any presentation on that day, but never mind, it already finished and it went out great..hehe..three cheers for me and my group, HIP,HIP,HIP..HOORAY...HOORAY...HOORAY..!! :)
Network Operating System
Okay, we are done with the cheering stuff, now to get serious.. First, I will tell you about Network Operating System ( NOS ). What is meant by NOS?
NOS is the software that runs on a server and enables the server to manage data, users, groups, security, applications, and other networking functions. The network operating system is designed to allow shared file and printer access among multiple computers in a network, typically a local area network (LAN), a private network or to other networks. The most popular network operating systems are Microsoft Windows Server 2003, Microsoft Windows Server 2008, UNIX, Linux, Mac OS X, and Novell NetWare.
So, that is the meaning and the functions of NOS. Now, I will tell about the types of NOS. There are two types of NOS; peer-to-peer and client/server types.
A short video on peer-to-peer and client/server networks
Peer-to-Peer :
In a peer-to-peer network operating system users are allowed to share resources and files located on their computers and access shared resources from others. This system is not based with having a file server or centralized management source. A peer-to-peer network sets all connected computers equal; they all share the same abilities to utilize resources available on the network.
Examples:
AppleShare used for networking connecting Apple products.
Windows for Workgroups used for networking peer-to-peer windows computers.
Advantages:
1) Ease of setup.
2) Less hardware needed, no server needs to be purchased.
Disadvantages:
1) No central location for storage.
2) Lack of security that a client/server type offers.
Client/Server :
Client/server network operating systems allow the network to centralize functions and applications in one or more dedicated file servers. The server is the center of the system, allowing access to resources and instituting security. The network operating system provides the mechanism to integrate all the components on a network to allow multiple users to simultaneously share the same resources regardless of physical location.
Examples:
Novell Netware
Windows Server
Advantages:
1) Centralized servers are more stable.
2) Security is provided through the server.
3) New technology and hardware can be easily integrated into the system.
4) Servers are able to be accessed remotely from different locations and types of systems.
Disadvantages:
1) Cost of buying and running a server are high.
2) Dependence on a central location for operation.
3) Requires regular maintenance and updates.
Okay, I think that is all about NOS types, functions, advantages and disadvantages. So, here, I also want to tell about our unexpected in-class presentation :)
My group have five peoples including me, my friends, Nazrin, Khai, Mamat and Anuar are such a big help in my group especially Nazrin. :) Our lecturer, En. Razak told us to pick our own topic and then, we took "Gateways" as our topic for the presentation. We found it is really hard to find information on gateways, so hard, but we tried our best and finally the presentation slide is done. YEAY..!!!! :)
This is the video on how to find IP address for your gateways, hope it help :)
A network gateway is an internetworking system capable of joining together two networks that use different base protocols. A network gateway can be implemented completely in software, completely in hardware, or as a combination of both. Depending on the types of protocols they support, network gateways can operate at any level of the OSI model. Because a network gateway, by definition, appears at the edge of a network, related capabilities like firewalls tend to be integrated with it. On home networks, a broadband router typically serves as the network gateway although ordinary computers can also be configured to perform equivalent functions.
Advantages :
1) Can translate information between different networks data formats or network architecture.
2) Most gateways operate at the application layer.
3) Can also be operated on network or session layer.
Disadvantages :
1. Gateways require greater processing limits due to protocol conversion.
2. They are slower than other network devices.
3. Installation and configuration of Gateway is more difficult, therefore requires special technicians.
4. It is more expensive than other devices.
Okay, I'm done. That all for now, see all of you in my next post. Do check in often, okay? Hope all of the blog entry notes will help all of you in understanding more on telecommunication & networking, okay? Thank you :)
In our 2nd class, we learn about Network Classification and Network Topology. When I learn about network classification, I get to know two more network types that are Wide Area Network (WAN) and Metropolitan Area Network. All this time I only know about Local Area Network (LAN), shame on me, huh? :(
Lets me tell you about these three types of network classification :
1) Local Area Network :
- These connect over a relatively small geographical are, typically connecting computers within a single office or building. In most cases they connect to a common electronic connection- commonly known as a network backbone. LAN's can connect to other networks either directly or through a WAN or MAN. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. Most LANs connect workstations and personal computers .
This is Local Area Network (LAN) diagram
2) Wide Area Network :
- These connect networks over a large geographical area, such as between different buildings, towns or even countries. A wide area network (WAN ) is a geographically dispersed telecommunications network . The term distinguishes a broader telecommunication structure from a local area network (LAN). A wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks.
This is a Wide Area Network (WAN) diagram
3) Metropolitan Area Networks :
- These connect networks around a town or city. it is smaller than a WAN, but larger4 than a LAN. A data network designed for a town or city. In terms of geographic breadth, MANs are larger than local-area networks (LANs) , but smaller than wide-area networks (WANs) . MANs are usually characterized by very high-speed connections using fiber optical cable or other digital media.

Enough with the network types, I would like you all to know about Network Topology. A small dialogue I created :)
Angah (Me) : Hey friends, let me introduce you to Network Topology.
Friends : Network Topology? Is it something or someone? *they were clueless...
NET. Topology : Hye all, I'm Net. Topology. Lets me tell all of you about myself, okay?
About Me (Network Topology)
- In computer networking, topology refers to the layout of connected devices. Think of a topology as a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network.
- Network topologies are categorized into the following basic types :
~ bus
~ ring
~ star
~ tree
~ mesh
Different types of network topologies
- Topologies remain an important part of network design theory. You can probably build a home or small business computer network without understanding the difference between a bus design and a star design, but becoming familiar with the standard topologies gives you a better understanding of important networking concepts like hubs, broadcasts, and routes.
Okay, THE END for the story of network topology and it also THE END for this entry. Thats all from me, hope all of you gain something new about networking. Do keep in touch, spread the word, spread the love, spread this BLOG... Merci beaucoup monsiuer et madamme moiselle :) *french language
Okay, this 2nd entry is about my first class for Telecommunication & Networking .. Fuuhhh..a long name for a subject right, it suit it name because it has a long history and gave big impact in our lives..We would lost connection without the presence of these Telecom or Networking..you all agree, right?
Telephone is one example of Telecommunication :)
Lets the real class begin, in our 1st class, we learned about data transmission, types of transmission and also the components.
1) Data Transmission :
- Data transmission is the transfer of data from point to point often represented as an electromagnetic signal over a physical point to point or point to multipoint communication channel.
2) Types of transmission :
- Two types, serial & parallel transmission.
Haha..I think it enough for today, right? Ops, forgot to tell you the meaning of telecommunication. It means, let me Google it first..wait......LOADING PAGE...opening Wikipedia...ahah, found it..Ok, seriously, TELE = Far Off ..so its means communication from a long distance between two or more peoples, if it only ONE people, that what we called, CRAZY..!!! :D LOL
Make sure it is two-ways from a distance communication, okay?
So, that all for now, I leave all of you with a great animation video. It really great, you all should check it out. This video show the funny side of HISTORY. You gonna like it.. :D
