Tpye of Network (ဒါကေတာ့ NetWoRK အမ်ိဳးအစားေလးေတြပါ)

  • LAN - Local Area Network

  • WLAN - Wireless Local Area Network

  • WAN - Wide Area Network

  • MAN - Metropolitan Area Network

  • SAN - Storage Area Network, It can also refer with names like System Area Network, Server Area Network, or sometimes Small Area Network

  • CAN - Campus Area Network, Controller Area Network, and often Cluster Area Network

  • PAN - Personal Area Network

LAN - Local Area Network

LAN connects networking devices with in short spam of area, i.e. small offices, home, internet cafes etc. LAN uses TCP/IP network protocol for communication between computers. It is often but not always implemented as a single IP subnet. Since LAN is operated in short area so It can be control and administrate by single person or organization.

WAN - Wide Area Network 

As “word” Wide implies, WAN, wide area network cover large distance for communication between computers. The Internet it self is the biggest example of Wide area network, WAN, which is covering the entire earth. WAN is distributed collection of geographically LANs. A network connecting device router connects LANs to WANs. WAN used network protocols like ATM, X.25, and Frame Relay for long distance connectivity. 

Wireless - Local Area Network  
A LAN, local area network based on wireless network technology mostly referred as Wi-Fi. Unlike LAN, in   WLAN no wires are used, but radio signals are the medium for communication. Wireless network cards are required to be installed in the systems for accessing any wireless network around. Mostly wireless cards connect to wireless routers for communication among computers or accessing WAN, internet.


MAN - Metropolitan Area Network
This kind of network is not mostly used but it has its own importance for some government bodies and organizations on larger scale. MAN, metropolitan area network falls in middle of LAN and WAN, It covers large span of physical area than LAN but smaller than WAN, such as a city.

 CAN - Campus Area Network
Networking spanning with multiple LANs but smaller than a Metropolitan area network, MAN. This kind of network mostly used in relatively large universities or local business offices and buildings.


  SAN - Storage Area Network
SAM technology is used for data storage and it has no use for most of the organization but data oriented organizations. Storage area network connects servers to data storage devices by using Fiber channel technology.     


SAN - System Area Network

SAN, system area networks are also known as cluster area network and it connects high performance computers with high speed connections in cluster configuration.

Gtalk virus

gtalk virus တစ္ေကာင္ေတြ႔လိုက္လို႔ပါ။ chrome ကိုေၿပာတာမဟုတ္ဘူး။ သတ္တာကလဲေတာ္ေတာ္ေလးလြယ္တယ္.
ေနာက္ virus က gtalk ပံုစံအတုလုပ္ထားတာဆိုေတာ့ေတာ္ေတာ္မ်ားမ်ားကမရိပ္မိၾကပဲ user name password ေတြကိုရိုက္ထည့္တတ္ၾကလို႔ပါ။ virus နာမည္က googleserv.exe ၿဖစ္ပါတယ္။
ဒီ virus အကူးစက္ခံရတဲ့စက္မွာဆိုရင္ virus က \Program Files\Google\Google Talk ထဲက googletalk.exe ကိုေဖ်ာက္ၿပီး gtalk.exe(virus) တစ္ခုထားခဲ့ပါတယ္။ ေနာက္ desktop ေပၚက Google Talk shortcut ကိုလဲ target မွာ gtalk.exe ကိုညႊန္လိုက္ပါတယ္။ Shortcut ကိုႏွိပ္တဲ့အခါ virus ကို runမိသြားၿပီး Gtalk windows အတုေပၚလာပါတယ္။ အဲ့ဒီမွာကိုယ္ရိုက္ထည့္လိုက္တဲ့ data ေတြကိုမွတ္သြားၿပီး pen drive ထဲကို sys/computername.nfo ဖိုင္အေနနဲ႔ထည့္ပါတယ္။ အဲ့ဒါဘာေၾကာင့္လဲေတာ့နားမလည္ပါ။ nfo ကို edit လုပ္ၾကည့္မယ္ဆိုရင္အထဲမွာ [username] နဲ႔ set=0x(numbers) ဆိုတာမ်ိဳးေတြ႔ရပါတယ္။ password ကိုေတာ့ encrypt လုပ္ထားပံုပါပဲ. ဒါေပမဲ့ စာလံုးေရကိုေတာ့ခန္႔မွန္းလို႔ရႏိုင္ဟန္တူပါတယ္။
User name password ရိုက္ၿပီးသြားလို႔ enter ေခါက္လိုက္ရင္ connect လုပ္ေနပံုၿပၿပီး error box က်လာပါမယ္။ OK ႏွိပ္လိုက္ရင္ေတာ့ သူ႔ window ပိတ္သြားၿပီး တကယ့္ gtalk ပြင့္လာပါမယ္။
ဒါေပမဲ့ေနာက္ကြယ္မွာေတာ့ သင့္ user name ကသူမွတ္ထားတဲ့စာရင္းထဲပါသြားၿပီဆိုတာသတိၿပဳပါ။

virus ကိုဖြင့္မိထားတာလား ဘယ္လိုသိမလဲ?
လြယ္ပါတယ္။ Virus ကိုဖြင့္မိထားတာဆိုရင္ taskbar က gtalk icon ဟာ sign-in မ၀င္ရေသးပဲနဲ႔ အၿဖဴေရာင္ၿဖစ္ေနပါမယ္။ pointer ေထာက္ၾကည့္ရင္ Google talk လို႔ေပၚရမယ့္အစား Gtalk.exe လို႔ေပၚပါမယ္။ ေနာက္တစ္ခုအေနနဲ႔ သူ႔ window မွာ check box (remember password) ေတြဘာေတြကအလုပ္မလုပ္ပါဘူး။ ၿပီးေတာ့ user name password ရိုက္ထည့္ၿပီး enter ေခါက္လိုက္တဲ့အခါမ်ိဳးမွာ text area ေတြက အညိဳေရာင္ေၿပာင္းၿပီး connecting ပံုစံမ်ိဳးၿဖစ္ေနပါမယ္။

ဘယ္လိုသတ္မလဲ
Desktop ေပၚက shortcut မွာ gtalk.exe အစား googletalk.exe လို႔ၿပန္ေၿပာင္းရိုက္ပါ။
\Program Files\Google\Google Talk ကိုသြားၿပီး Gtalk.exe ကိုဖ်က္လိုက္ပါ။

ဒီ virus ကကူးစက္ႏႈန္းမၿမန္ပါဘူး။ ဆိုင္ေတြမွာလဲေတြ႔ရခဲပါတယ္။ ဘာပဲၿဖစ္ၿဖစ္ေတြ႔ခဲ့တယ္ဆိုရင္ ေရွာင္ရွားႏိုင္ၾကေစဖို႔ဆႏၵၿပဳပါတယ္။ :)
