What is client server ?

Clientserver describes the relationship between two computer programs in which one program,the server, which fulfills the request .

 

There are some advantages and disadvantages of Client/Server Networks

Advantages :

•A client server can be scaled up to many services that can also be used by multiple users

•All data is stored on the servers, which generally have far greater security controls than most  clients.

•The security is a lot more advanced than a peer to peer network

Disadvantages :

•When the servers goes down or crashes . All the computers connected to it become unavailabe to use

•More expensive than a peer to peer network.You have to pay for start up cost

What is peer-to-peer ?

•  Peer-to-peer (P2P) is a distributed application architecture that partitions tasks or workloads between peers.

There are some advantages and disadvantages of Peer-to-Peer networks

Advantages :

•Peer to peer networks are easy and simple to set up and only require a Hub or a switch to connect all the computers together.

•You can access any file on the computer as long as it is set to shared folder

•This is rather cheap than having server

•If one computer fails to work all the other computers connected to it contiune to work

Disadvantages :

•If you have connected the computers together properly then therre can be problems accessing certain files

•Security is not good and you can set passwords for files that you don’t want people to access but apart from that the security is pretty poor.

• Jarak > 100 Km 
• KecepatanTransmisi 64 kbps (kilobitpersecond)

 - Jenis jenis jaringan berdasarkan media transmisi :

• Berdasarkan Media Transmisinya  :

1.Jenis Jaringan Kabel, contoh : LAN

2.Jenis Wireless (nirkabel)

 ~WLAN (Wireless Local Area Network)

• WLAN menggunakan medium gelombang elektromagnetik.  

• KEUNGGULAN :
• 1.MOBILITAS
• 2.KECEPATAN INSTALASI
• 3.FLEKSIBILITAS TEMPAT
• 4.PENGURANGAN ANGGARAN BIAYA
• 5.JANGKAUAN LUAS

• KELEMAHAN :
  1.Transmit data 1 – 2 Mbps
  2.Alatnya Mahal
  3.Propagansi radio (interferensi gelombang)
  4.Kapasitas jaringan terbatas
  5.Keamanan data kurang terjamin
  6.Intermittence (sinyal putus-putus)
