BANDWIDTH MANAGEMENT

             (benda ni lama dah belajar... postnyer baru nak buat ha... huhuhuhuhu) maklumat akan ditambah lagi      

   - is the process of measuring and controlling the communications (traffic, packets) on a network link, to avoid filling the link to capacity or overfilling the link, which would result in network congestion and poor performance.

Apa Itu Bandwidth

 = Bandwidth adalah luas atau lebar cakupan frekuensi yang digunakan oleh sinyal dalam medium transmisi. Dalam kerangka ini, Bandwidth dapat diartikan sebagai perbedaan antara komponen sinyal frekuensi tinggi dan sinyal frekuensi rendah. frekuensi sinyal diukur dalam satuan Hertz. sinyal suara tipikal mempunyai Bandwidth sekitar 3 kHz, analog TV broadcast (TV) mempunyai Bandwidth sekitar 6 MHz. Bandwidth diartikan juga sebagai takaran jarak frekuensi. Dalam bahasa mudahnya, adalah sebuah takaran lalu lintas data yang masuk dan yang keluar.

TCP / IP UTILITIES

now im story about tcp/ip utilities..
just simple word to know...




Connectivity utilities

Utility	Description
Ftp	Transfers files of any size between computers running Windows Server 2003 operating systems and any computer running File Transfer protocol (FTP) server software. For more information, see Ftp.
Lpr	Sends print jobs to remote UNIX printers managed by Line Printer Daemon (LPD) print server software. For more information, see Lpr.
Rcp	Copies files between computers running Windows Server 2003 operating systems and computers running Remote Copy protocol (RCP) server software. For more information, see Rcp.
Rexec	Executes processes on remote computers. For more information, see Rexec.
Rsh	Runs commands on a computer running Remote Shell (RSH) server software. For more information, see Rsh.
Telnet	Uses terminal-based login to remotely access network devices that are running Telnet server software. For more information, see Telnet.
Tftp	Transfers small files between computers running Windows Server 2003 operating systems and computers running Trivial File Transfer protocol (TFTP) server software. For more information, see Tftp.

Diagnostic utilities

 

Utility	Description
Arp	Displays and modifies the Address Resolution protocol (ARP) cache. This cache is a local table used to resolve IP addresses to media access control addresses used on the local network. For more information, see Arp and Address Resolution Protocol (ARP).
Hostname	Returns the host name of the local computer. For more information, see Hostname.
Ipconfig	Displays the current TCP/IP configuration. Also used to manually release and renew TCP/IP configurations assigned by a DHCP server. For more information, see Ipconfig and Command-line utilities.
Lpq	Obtains print queue status information from computers running Line Printer Daemon (LPD) print server software. For more information, see Lpq.
Nbtstat	Displays the local NetBIOS name table, a table of NetBIOS names registered by local programs, and the NetBIOS name cache, a local cache listing of NetBIOS computer names that have been resolved to IP addresses. For more information, see Nbtstat and Release and refresh NetBIOS names by using the nbtstat command.
Netsh	Displays and administers TCP/IP protocol settings on the local computer or a remote computer. For more information, see Netsh commands for Interface IP.
Netstat	Displays TCP/IP protocol session information. For more information, see Netstat.
Nslookup	Checks records, domain host aliases, domain host services, and operating system information by querying DNS servers. For more information, see Nslookup and Verify DNS registration for domain controllers using the nslookup command.
Ping	Verifies configurations and tests IP connectivity. For more information, see Ping and Test a TCP/IP configuration by using the ping command.
Route	Displays or modifies the local routing table. For more information, see Route.
Tracert	Traces the route a packet takes to a destination. For more information, see Tracert and Trace a path by using the tracert command.
Pathping	Traces the route a packet takes to a destination and displays information on packet losses for each router in the path. Pathping can also be used to troubleshoot Quality of Service (QoS) connectivity. For more information, see Using the pathping command.

Server-based software

 

Server software	Description
TCP/IP Printing service	The TCP/IP Printing service offers an LPD printing service. This service allows UNIX computers to send print jobs to computers running Windows Server 2003 operating systems by using the Line Printer Remote (Lpr) utility for printing.
Internet Information Services	Internet Information Services (IIS) offers Web, Gopher, and FTP server software for providing TCP/IP-based publishing services. IIS is provided to offer an enterprise-ready Web server to use with an unlimited number of simultaneous connections.
Peer Web Services	Peer Web Services is provided with Windows XP Professional to provide Web-publishing services similar to those offered by IIS for serving fewer than 10 simultaneous connections.

TERTUNGGAK!!!

(tertunggak lama dah ha.. pdhal dh bt lama dh but wat i saving to publish telah dikhianati oleh virus yg xbertauliah lsng..  pnya dh create manyak cantik tetiber wa pny doc buleh h\ilang oooOOO.. manyak tnsion la..


so juz review jer..
