Thin client (SD305 ) uses China-designed IC,
ARCA 210 CPU which is a 400 MHz, RISC central
processor It has features of low heat dissipation;
no needs for fan and offering higher level of security.

SD305 has a memory of 64 MB RAM.
It adopts Kernel boot in DOC (disk on Chip) technology.
The system core is stored in the client’s built-in motherboard.
That secures the safety and system stability and prevents
virus attack and threat or break from external softwares.


◆Centralized information management, reducing information redundance
◆Servers in charge of virus prevention, lowering risks caused by front-end users.
◆Frequent updates of service packs, minimizing the hackers’ attack.
◆Information and data are stored in server using RAID levels 0 and 1.
◆Risk reduction of data loss and lower the occupancy of web usage
◆Lower total cost than PC
◆Client efficiency is improved following the server efficiency improvement

 


    Comparison of SD305 thin client with PC
 
  SD305 thin client PC
Total cost
Thin client’s hardware is relatively lower in cost. It has no need for updates. No needs for maintenance
PC’s hardware is rather costly. It needs frequent updates and maintenance.
Management
 Set-ups in server only by MIS can control the frond-end thin clients.It makes easier for centralized managements
Need to set-up each PC individually. It is time consuming and leakage may occur.
Security
Without built-in data retrieving devices, the front-end users can not steal data. Security is well ensured. No means for data security. Data can be stolen.
Maintenance
 The system up-grade or software maintenance are carried out on server only. The damage in thin client would not affect the stored data in server.
For every virus- attacked and damaged PC, user needs to maintain individual PC.
Performance
 The front-end terminal efficiency is provided by the server. An efficient server makes an efficient internet environment.
 Both front-end and back-end efficiencies are important for an efficient internet environment.
