Chia VLAN trên SW có 2 bước

Chia VLAN trên SW có 2 bước:
1. Tạo VLAN
2. Gán SW port vào VLAN có 2 kiểu:
- Static: áp dụng cho các mạng nhỏ và gán port vào VLAN nhân công
- Dynamic

Nếu bạn sử dụng SW Catalyst 2900XL tạo VLAN static thì bạn có thể cấu hình như sau:
1. Tạo VLAN
vlan database
vlan #vlan name vlanname
Chú ý: không nên sử dụng VLAN 1 nếu không muốn cho telnet vào SW
2. Gán SW port vào VLAN
interface FastEthernet 0/n
switchport mode access
switchport access vlan
số thứ tự (số hiệu) của Vlan
VD:
vlan database
- tao vlan 10 dat ten la nguyen
#>vlan 10 name nguyen
- tao vlan 20 dat ten thuy
#>vlan 20 name thuy

vay la ta co 2 vlan10 va vlan20 mac dinh co them vlan1
gan port vao vlan
#>config
interface FastEthernet 0/1
switchport mode access
switchport access vlan10
exit
interface FastEthernet 0/2
switchport mode access
switchport access vlan20
exit
lenh tren gan FA0/1 vao vlan10
lenh tren gan FA0/2 vao vlan20

dung lượng RAM lớn nhất mà HĐH cấu trúc 32-bit nhận được

Hình ảnh
dung lượng RAM lớn nhất mà HĐH cấu trúc 32-bit nhận được 1Gb =1024MB 1Mb=1024Kb 1Kb=1024byte 1byte=8bit Như vậy 1Gb ram sẽ có chứa số bit là 2^10 x 2^10 x 2^10 x 2^3 = 2^33 bit. 4Gb ram sẽ là 2^2 x 2^33 = 2^35 bit. Vậy với 4Gb ram sẽ có 2^35 địa chỉ ô nhớ . Trong khi đó win 32 bit chỉ hỗ trợ max là 2^32 bit địa chỉ ô nhớ. Chính vì sự chênh lệch này mà nó sẽ ko thể nhận đủ 4Gb ram khi hoat động. Win 64bit thì support vô tư vì nó có thể xử lí được đến 2^64 địa chỉ ô nhớ Due to fallout from a recent computer catastrophe at work, I had the opportunity to salvage 2 GB of memory. I installed the memory in my work box, which brings it up to 4 gigabytes of RAM-- 4,096 megabytes in total. But that's not what I saw in System Information: Only 3,454 megabytes. Dude, where's my 4 gigabytes of RAM? The screenshot itself provides a fairly obvious hint why this is happening: 32-bit Operating System . In any 32-bit operating system, the virtual address space is limited, by definiti

Ubuntu LAMP Server

Get this content from link http://www.zaphu.com/2007/08/07/ubuntu-lamp-server-setup-guide-with-desktop-gui/ Step 1: Install Ubuntu Server Edition with LAMP server components. Download the disk image (*iso) for Ubuntu Server Edition (currently version 8.04 Hardy Heron) and burn it to a CD. Ensure that your BIOS is configured to boot from the CD-ROM drive. Restart with the Ubuntu disk in the drive and the machine should boot into the Ubuntu installation shell. If you would like to configure a static IP address, select F6 - Other Options and enter netcfg/disable_dhcp=true at the end of the options string, and the install script will prompt you for network information during the installation. Otherwise, the static IP must be configured post installation as per the second part of step 2 below, and your network will be automatically configured using DHCP (as long as DHCP is enabled on your router). In either scenario, you must enter a hostname when prompted. As you work through the installat
