power supply problem



Why CPU keep on restarting?

- Probably your power supply is overheating

- Power suplly is easy to repair

- Usualy capacitor is leaking

- look closely the capacitor whos deform

- and replace it with same value


//do you know how to power on the power supply without connecting to the motherboard?//

just hold the wire whos 24 pens short the green wire and the gray one .

// to check it

get multi- tester

get the 4 wires
the
red,black = 5v
yellow,black=12v

how to fix motherboard


usually motherboard defect is capacitors

1. Identify first the busted capacitor ?
How-- look each capacitor which is deform or blown
2. See the Value of capacitors
How-- look closer to the capacitor write down the value
usually 6.3v 1500uf // note : if you cannot find same value change all the capacitor that have
the same value and it with the new value
//now you identify and get the value of the capacitor
3. Now remove carefully the busted one
using soldering iron
How -- simly put the tip of soldering iron into the led and when it melt pull the capacitor slowly
4. replace a new capacitor which the same value // note: look the polarity or else the
motherbord get risk
5. now you already done, check all the capacitor terminals look if there is no flooting led

Straight-Through Wiring /Cross-Over Wiring


COLOR-CODE STANDARDS
These are the pin-out diagrams for straight through and crossoverUTP Ethernet cables.





The TX (transmitter) pins are connected to corresponding RX (receiver) pins, with plus to plus and minus to minus. A coss-over cable must be used to connect units with identical interfaces. When straight-through cables are used to connect Ethernet devices, one of the two units must, in effect, perform the cross-over function. This is the reason that straight through cables work directly between hubs or switches and NIC cards.... the Hub or Switch is designed so that their RJ45 Jacks are pre-wired with the transmit and receive pairs already reversed.
There are two color-code standards in common use: EIA/TIA 568A and EIA/TIA 568B. These standards derive from TELCO usage and the pairs shown correspond to four phone lines, each with its own line pair. This same wiring was adopted for LAN standard Ethernet RJ45 wiring as well. RJ45 receptacle wiring for both standards are shown below:

Note: Only pairs 2 and 3 are used for Standard Ethernet wiring. Pairs 1 and 4 can be used for other purposes such as telephones or even a second separate, complete Ethernet connection.
Straight-Through Wiring Using The 586A Standard


The flat wiring diagram, above, shows the 568A color code standard as the wiring for the PC side of the cable and the same 568A standard for the Hub, Switch or Router side of things (assuming that the Hubs, Switches or Routers are wired internally to perform the cross-over function). The illustration depicts the wiring arrangement before insertion into an RJ45 connector prior to crimping.

Cross-Over Wiring Using The 568A to 586B Standards

The flat wiring illustration, above, shows cross-over cable wiring using the 568A color code standard as the wiring for the PC side of things and the 568B standard for wiring to the other PC. Note that in both cases, all eight wires are shown but only four are actually needed.
Pins 4, 5, 7, and 8 and the blue and brown pairs are not used in either standard. Contrary to common tech-lore and what you may have read elsewhere, these pins and wires are not used or required to implement 100BASE-TX duplexing. In fact, they can be used for other purposes such as a single line phones or even operating two separate Ethernet channels, provided care is taken to assure that these wire pairs are isolated from the other wires.
In practice, making actual RJ45 Patch cables is not physically that simple. The connections of the pairs to the pins in the RJ45 jack isn't wire pair by wire pair. Instead, the orange pair of wires are not adjacent and the blue pair is upside-down. If fact, flattening out the cables in the correct order for insertion into the RJ45 jack before crimping is by far the most complex part of the job of making twisted pair Ethernet patch cables.
One cannot use flat-untwisted telephone cable for a network cable that runs any appreciable distance. One must use a pair of twisted wires to connect a set of transmitter pins to their corresponding receiver pins. One cannot use a wire from one pair and another wire from a different pair... See the theory page for the reasons why.
Blue Max designed a RJ45 wiring card so new technicians won't have trouble remembering how to wire straight-through and cross-over cables. These are business card size and are printed on both sides of business card stock. One side shows the 568A standard at both ends (a regular straight-through cable). There's a fold mark at about 1/3 of the way across the card. To see the wiring for a cross-over cable, the user simply folds the card to see the wiring of a cross-over cable with the 568A standard on one end and the 568B standard on the other.
A sample of the card is shown below, along with a down-loadable .PDF File of the front and rear of the card along with the front and back of the card in Microsoft Word. These are designed for printing on Avery Stock 8371.

Computer Output Devices

Output Device
- Monitor - A monitor is the screen on which words, numbers, and graphics can be seem. The monitor is the most common output device.
- Compact Disk - Some compact disks can be used to put information on. This is called burning information to a CD. NOTE: A CD can also be an input device.

- Printer - A printer prints whatever is on the monitor onto paper. Printers can print words, numbers, or pictures.

- Speaker - A speaker gives you sound output from your computer. Some speakers are built into the computer and some are separate.

- Disk Drives - A disk drive is used to record information from the computer onto a floppy disk or CD.

-Floppy Disk - A floppy disk is used to record information on. The information is stored on the floppy disk and can be used later or used on another computer. NOTE: A Floppy can also be an input device.

-Headphones - Headphones give sound output from the computer. They are similar to speakers, except they are worn on the ears so only one person can hear the output at a time

Type of Network Topologies

Network Topologies

Topology: The physical and/or electrical configuration of cabling and connections comprising a network -- the shape of the system.
Topology Types
Every network has a "shape" which is normally refered to as its topology. There are five major topologies in use today: Bus, Ring, Star, Tree, and Mesh. Each is used for specific network types, although some network types can use more than one topology. For example, Ethernet networks can be laid out in a Bus, Star, or Tree topology, or any combination of the three. Token ring is physically laid out in a Star, but electrically behaves like a Ring. To properly understand each network type requrires first understanding the basic topologies.

Bus topology
The simplest topology to understand is the Bus. In a Bus, all the devices on the network are connected to a common cable. Normally, this cable is terminated at either end, and can never be allowed to form a closed loop. Figure One shows an example of a Bus network.

Ring topology
A Ring topology is very similar to the Bus. In a Ring, all the devices on the network are connected to a common cable which loops from machine to machine. After the last machine on the network, the cable then returns to the first device to form a closed loop. Figure Two shows an example of a Ring network.

Star topology
A star topology is completely different from either a Bus or a Ring. In a Star. each device has its own cable run connecting the device to a common hub or concentrator. Only one device is permitted to use each port on the hub. Figure Three shows an example of a Star network.


Tree topology
A tree topology can be thought of as being a "Star of Stars" network. In a Tree network, each device is connected to its own port on a concentrator in the same manner as in a Star. However, concentrators are connected together in a heirarchial manner -- i.e. a hub will connect to a port on another hub. Figure Four shows a Tree network.

Mesh topology
A Mesh topology consists of a network where every device on the network is physically connected to every other device on the network. This provides a great deal of performance and reliability, however the complexity and difficulty of creating one increases geometrically as the number of nodes on the network increases. For example, a three or four node mesh network is relatively easy to create, whereas it is impractical to set up a mesh network of 100 nodes -- the number of interconnections would be so ungainly and expensive that it would not be worth the effort. Mesh networks are not used much in local area networks (LANs) but are used in Wide Area Networks (WANs) where reliability is important and the number of sites being connected together is fairly small. Figure Five shows an example of a four-node Mesh network.

Computer input devices

Input Devices
Input devices are things we use to put information INTO a computer.
Here are some examples of input devices.
Note: An APPLICATION is a type of computer program. Some applications are word processing, spreadsheets, databases, and games

* Camera - most cameras like this are used during live conversations. The camera transmits a picture from one computer to another, or can be used to record a short video.

* Compact Disc (CD) - CDs store information. The CD can then be put into another computer, and the information can be opened and added or used on the second computer. Note: A CD-R or CD-RW can also be used as an OUTPUT device.

* Keyboard - The keyboard is a way to input letters or numbers into different applications or programs. A keyboard also has special keys that help operate the computer.

* Mouse - The mouse is used to open and close files, navigate web sites, and click on a lot of commands (to tell the computer what to do) when using different applications.

* Digital Camera - A digital camera can be used to take pictures. It can be hooked up to a computer to transfer the pictures from the camera to the computer. Some digital cameras hold a floppy disk, and the floppy disk can be taken out of the camera and put directly into the computer.

* Drawing Tablet - A drawing tablet is similar to a white board, except you use a special pen to write on it and it's connected to the computer. Then the word or image you draw can be saved on the computer.

* Microphone - A microphone is used to record sound. The sound is then saved as a sound file on the computer.

* Scanner - A scanner is used to copy pictures or other things and save them as files on the computer.

* Disk Drive - A disk drive can hold a CD or a floppy disk. It reads the information on the disk so that the computer can use it.

* Joystick - A joystick is used to move the cursor from place to place, and to click on various items in programs. A joystick is used mostly for computer games.

* Touch Screen - A touch screen is a computer screen or other screen that you can touch with your finger to enter information. Examples of touch screens include a smart board, a microwave, a dishwasher, or an ATM at a bank.

* Bar Code Scanner - A bar code scanner scans a little label that has a bar code on it. The information is then saved on the computer. Bar code scanners are used in libraries a lot.

Intel versus Amd

Everyone today expect there computer to be fastest. They expect it to be rigged with the latest technology and the fastest chip. So which one will you go for? Choosing a chip for your computer is an arduous path up the hill. Should it be an AMD Athlon? Are Intel processors better performance oriented? Which processor should you go for? I’m not going to answer any of these, as it can be addressed only you. You need to determine what is dexterous for you under which circumstances. To determine this you may need to compare them on few parameters.

in my case i prefered to use amd !!
- less power consumption
- it's faster in terms of gaming
- it's multitasking
- its cheeper than intel
