Hari Terbahagia Sebelum Berakhirnya Tahun 2017

Assalamualaikum . hai apa khabar korang ? sihat ke tidak ? hiihihi . 27 Disember 2017 baru-baru ini keputusan peperiksaan PSPM 1 telah diedarkan . Ya Allah , syukur tidak terhingga kepada-Mu Ya Allah atas rezeki yang kau berikan kepadaku ini . Tak sangka juga sebenarnya dapat pointer yang agak tinggi . Walaupun bukan 4.0 , tapi saya bersyukur sangat-sangat dengan result saya sebab itu hasil buah usaha saya selama berada disini . Nak tahu ke saya dapat pointer berapa ? Okey la , saya dapat 3.50 . Alhamdulillah bersyukur sekali lagi .

 وَمَنْ لاَيَشْكُرِ النَّاسَ لاَيَشْكُرِ اللهَ

“barang siapa yang tidak bersyukur kepada manusia, berarti ia tidak bersyukur kepada Allah”. (H.R Ahmad dan Baihaqi) 

عن ابى عبد الله عليه السلام قال : قال رسول الله صلى الله عليه وسلم : الطاعم الشكر له من الأجر كأجر الصائم المحتسب. والمعافى الشكر له من الأجر كأجر المبتلى الصبر. والمعطى الشّكر له من الأجر كأجر المحروم القانعز

“Dari Abu Abdillah a.s, beliau berkata, “bahwa Rasulullah saw. bersabda, “orang yang menyantap makanan dengan rasa syukur, maka dia diberi pahala, seperti orang yang berpuasa menjaga dirinya. Orang yang sehat yang mensyukuri kesehatannya, maka dia diberi pahala, orang yang menanggung penderitaan (jasmani)-nya dengan sabar. Dan orang yang memberikan dengan rasa syukur, maka dia mendapat pahala yang sama dengan orang yang menanggung kerugian dari menjaga diri”. (H.R Abu Hurairah dan al-Qudha’i)

Okey , seperti biasa minggu -3 ini saya melaksanakan assignment yang diberikan oleh pensyarah . Mari kita belajar , semoga menjadi rujukan buat semua . 

WHAT IS NETWORK ARCHITECTURE?

• The configuration of computers, devices and media on a network.

Categories of Network Architecture :	Description :
Peer-to-peer Network	Diagram of Peer-to-peer Network  - A simple, inexpensive network that typically connects fewer  than 10 computers.  - Each computer, called a peer, has equal responsibilities and capabilities. - Sharing hardware (such as a printer), data or information with other computers on the peer-to-peer network. - Each computer stores files on its own storage devices. Thus, each computer on the network contains both the server operating system and application software. - All computers on the network share any peripheral device(s) attached to any computer. - Peer-to-peer networks are ideal for very small businesses and home users. - Some operating systems, such as Windows, include a peer to-peer networking utility that allows users to set up a peer-to-peer network. - Peers are both suppliers and consumers of resources.
Client/Server Network	Diagram of Client/Server Network  •      One or more computers act as a server, and the other computers on the network request services from the server. •      Server, sometimes called a host computer, controls access to the hardware, software, and other resources on the network and provides a centralized storage area for programs, data and information. •      The clients are other computers and mobile devices on the network that rely on the server for its resources. •      For example, a server might store a database of customers. Clients on the network (company employees) access the customer database on the server. •      Client/server architecture works when the client computer sends a resource or process request to the server over the network connection, which is then processed and delivered to the client. •      A server can manage several clients simultaneously, whereas one client can be connected to several servers at a time, each providing a different set of services.  •      The Internet is also based on client/server architecture where the Web server serves many simultaneous users with Web page and or website data.

TYPES OF COMPARISON :	CLIENT-SERVER NETWORK	PEER-TO-PEER NETWORK
Basic	There is a specific server and specific clients connected to the server.	Clients and server are not distinguished; each node act as client and server.
Service	The client request for service and server respond with the service.	Each node can request for services and can also provide the services.
Focus	Sharing the information.	Connectivity.
Data	The data is stored in a centralized server.	Each peer has its own data.
Server	When several clients request for the services simultaneously, a server can get bottlenecked.	As the services are provided by several servers distributed in the peer-to-peer system, a server in not bottlenecked.
Expense	The client-server are expensive to implement.	Peer-to-peer are less expensive to implement.
Stability	Client-Server is more stable and scalable.	Peer-toPeer suffers if the number of peers increases in the system
