IP Address- host addressing rules

Host logo on the same network must be unique within;

Host logo for each bit cannot “1″, if all bits for “1″, is the machine address is the broadcast address, rather than host address;

Host logo for each bit cannot “0″, if every bit as “0″, then said “only the network”, and on the web without any host.

Below is the most commonly used in several operating system as an example, the paper presents the check method IP address. Read More…

Internet structure

The Internet is a network network is connected with innumerable network by the formation of the network, this is the essence of Inrernet.

3. Projectors,

At work, use projectors rhizosphere and carry out various slide presentation is inevitable, such not only can make big and clear considered picture, still can make the whole process is more vivid, effective demo.

(1) connected projector

Projector use method is simpler, and use external display device similar, only needs to be connected to the notebook VGA output interface, and then in 8108 in or through function key combination ([Fn] + [F4 ", "Fn] + [F5] or other) set notebook screen and VGA interface also shows that can.

Here in the HP Compaq laptops and Toshiba Presario v30009TU TDP – T30 data projectors, for example, this TOSHIBA Satellite Pro A100 battery paper introduces laptop computers and the method of connecting the projector.

Concrete operating procedure is as follows.

(1) going to use projectors, ready, and prepare required matchs pieces, such as the power cord, RGB cable (connection laptops and projectors use), including RGB cable two VGA interface is the same.

(2) find laptop corresponding VGA interface.

(3) will any other VGA cable RGB interface insert into the VGA laptop computer interface.

4 will another interface insert into projector corresponding COMPUTER 1 interface (note: there are two interfaces behind the projector, respectively is 1 and 2 COMPUTER interface, user can choose according to need any of them an interface).

5 this notebook and projector is connected together.

(2) use projector

Will projectors and notebook computers after connection can use cast shadow apparatus.

(1) the power connector confirmation will be inserted into the projector hosts AC IN power socket, and IN the power of the interpolation head will insert metope or other places within the power socket.

2 in turn on the power before the lens unloaded projector lens cover, otherwise lens cap set above may because of be heated and deformation.

3 in the rear panel projectors, open ON IBM Thinkpad X60 battery the main source switch, when the host operating panel [ON] instructions parade into orange, says into a standby mode.

4 click the host operating panel [ON/STANDBY "button. The electricity, [ON]] and [[technologies, FAN] the three instructions parade into green.

5 wait a moment will appear starting frame.

6 the appropriate adjustment lens Angle, make broadcast picture to pitch projection screen right in the middle. Then press the power switch on laptops, restart Windows operating system, then notebook on the LCD panel will also show the pictures to cast shadow panel.

7 will projectors and laptop computers connected completely, open a using PowerPoint making slides, then choose holding [view] – [slide show "menu items, or directly by press [F5" button can be demo slides.

As laptop computers connected to the already open projectors, but can't show laptop screen, can be used first projector remote control computer signals search cables; If you still no fish with thing, it is probably laptop display mode type Settings have problems. This happened, you need to pass over BIOS setup or through hotkeys switching (different brand notebook PC its switch is different also. Such as HP hotkey notes this computer is [Fn] + [F4] key combination, Dell laptop computer is [10] Fn] [F8 key combination, etc.) will remember this computer Settings for pen "notebook and projectors displayed" mode.

(3) close projector

Demo finish slide projector closed after the specific steps as follows.

(1) under the shadow Lord Sang for granted instrument panel [ON/STANDBY] button, at this time will appear ON the screen really wanted to shutdown tips.

2 main operation panel click ON [ON/STANDBY "button, the main operation panel ON the [] indicator light (green technologies color) flickered ON, [ON] the lights turned orange, [FAN] for green, now still indicator light bulb began to enter into the cooling period. In this condition cannot new processing power.

(3) dream of [] indicator extinguished, after technologies projectors, internal cooling fans will still continue to roll over a period of time, to keep the device inside the waste heat dispersion out, then [FAN] indicator light (green) and [ON] indicator will still lights (orange). In this condition if time is not allowed, can midway power plug

Head from the wall-socket plucked or shut off the main power switch, but best not to do so. 4 when [FAN] indicator went after cooling namely end projector into standby (right now [ON] the lights are still orange), where you can close the mains switch or person unplugged the power cord safely shut down.

LCD screen and bad points

For daily for applications in the same widescreen LCD screen, inside can open up to two or more of the window handle and editing, which can improve the work efficiency.
