AGP (Accelerated Graphics port) Pin Details With Voltage

ALL ABOUT AGP SLOT,PIN DETAILS AND VOLTAGES FOR MOTHERBOARD REPAIR

The Accelerated Graphics Port (also called Advanced Graphics Port) is a high-speed point-to-point channel for attaching a single device (generally a graphics card) to a computers motherboard, primarily to assist in the acceleration of 3D computer graphics. Many classify AGP as a type of computer bus, but this is something of a misnomer since buses generally allow multiple devices to be connected, while AGP does not. AGP originated from Intel, and it was first built into a chipset for the Pentium II microprocessor

Principle and maintenance process of the CPU power supply circuit

Recently a lot of friends in the Q group or Q I run FF00 test card, where to the repair, the CPU does not work, how measured, and so on, and asked much more have trouble, simply put the CPU power supply circuit principle and maintenance of processes to write about those who ask to look at the line.
　　Monitor point does not shine, overhaul focus the CPU power supply circuit, the CPU power supply circuit is the most fragile in the maintenance of an area, it damaged the test card display FF00. Board can be added to electricity, but the CPU does not work, because the CPU needs a stable power supply current, in order to work.

MOSFET is good or bad test on the motherboard (using resistance measurement method)

MOTHERBOARD MOSFET TESTING METHOD.

FETs of all types are widely used electronics components today. Of all the types of FET, the MOSFET is possibly the most widely used.

Even though MOSFETs have been in use for many years, these electronics components are still a very important element in today's electronics scene. Not only are MOSFETs found in many circuits as discrete components, but they also form the basis of most of today's integrated circuits.

MOSFETs provide many advantages. In particular they offer a very high input impedance and they are able to be used in very low current circuits. This is particularly important for integrated circuit technology where power limitations are a major consideration

The method of measuring resistance is measured with a multi meter FET source electrode and the drain, gate and source pole resistance value indicated by the resistance value between the gate and drain, gate G1 and the gate G2 and the MOSFET manual are consistent to distinguish good and bad of the tube. Specific methods : first placed in the multi meter R × 10 or R × 100 files,

Hard disk drive definition

ALL ABOUT HARD DRIVE OR HARD DISK.


hard disk drive is an essential and still probably the most mysterious component of a personal computer device. A hard disk drive is actually a closed device that your Computer uses for nonvolatile data storage. Nonvolatile, as well as semi permanent, storage space means that the actual storage space device keeps the information no matter if absolutely no electrical power is supplied to the pc. Because of the hard disk drive is expected to keep information until they are intentionally deleted or just over-written, the hard drive is needed to carry necessary computer programming along with data. Consequently, once the disk drive does not work properly, the effects are generally extremely serious. To keep, service, and upgrade your personal computer system correctly, you must learn the hard drive works.

Hard disk heads and platters.

The principle of hard drives

Basic principle of hard drives and floppy disks work are almost identical: the data is written and read by the universal read-write heads from the surfaces of the rotating magnetic disk, divided into tracks and sectors (512 bytes each), as in Fig. 1


In storage rings are usually installed multiple drives, and data is written on both sides of each of them. Most drives have at least two or three discs (which can record on four or six sides),

What isTrack and sector in Harddrive.

HARDISK TRACK AND SECTOR EXPLAINED.

Track – this is one “ring” of the data on one side of the disk. Track record on the disk is too large to use as unit of information storage. In many drives, the capacity of more than 100 thousand bytes, and gives the unit for storing small files are very wasteful. Therefore, the tracks on the disk is divided into numbered segments called sectors.

USB Front Panel Pinout Assignment

The following image is the USB Front Panel Pin out Assignment.

Some of old computer cases have divided the USB front cable. Usually there are 8 cables with a port on each cable. Every port marked with a note: “VCC” for red cable ; “GND” for black cable ; “D+” for green cable ; and “D-” for white cable. If your computer case has this kind of ports, then you should arrange the USB front panel port refer to above USB pinout connection.

Wi-Fi and Bluetooth. What is the difference?

WHAT IS WI-FI AND BLUETOOH.


Most people have little knowledge or did not understand at all what is wifi and bluetooth, which it are a wireless data transmission standard.
This is one of the reasons is a common misconception that these are two names for the standard wireless connection. However, it is misleading – because between these two standards, there is a huge difference.

Let’s learn what the difference is the bluetooth and wifi :

1) Scope
Wi-Fi – the standard, the main purpose is to get rid of clutter – in offices and homes in the construction of local networks.
At home, using Wi-Fi lets you quickly create an efficient network in the office – reducing the cost of building the network by saving on wiring.
Bluetooth – created as a standard for wireless data transfer between 2 devices – cell phones, PDAs or computers (any combination).

Memory and CPU matching method

Problems with memory and CPU, is one of the greatest concern of computer enthusiasts. How to match? Hundreds of articles on the Internet, to see dazzling, if not carefully analyze and judge, it is difficult to distinguish which is correct, which is wrong. According to my analysis, the formation of this situation for several reasons: First, the CPU FSB, with the front-side bus frequency is often mixed, and sometimes also the front-side bus with HT bus can also be confused; three kinds of memory (SDRAM, DDR1 SDRAM DDR2 SDRAM) characteristics,

ALL ABOUT LCD MONITORS

LCD monitors: the proportion of screen ratio screen is vertical and horizontal ratio of the screen, the screen aspect ratio is the ratio of two integers to represent, you can also use a decimal, such as 4: 3 or 1.33. Ordinary computer monitor and the data signal and TV signal aspect ratio of 4: 3 or 1.33, film, DVD and high definition television aspect ratio of 16: 9 or 1.78. When the aspect ratio of the input source image aspect ratio display device support, image distortion and missing. 16: 9 images displayed in 4:3, there are three kinds: the first one is the deformation (Anemographic) mode, in the case of the level is full, vertically elongated, until it fills the screen, so the image looks thinner than the original ;

NIC interface type(NETWORK INTERFACE CARD)

NIC: the
NIC in charge of the cable interface type is with the network connection, so it must have an interface cable to connect through it and other computer network equipment. Different network interface for the different network types, the common interface Ethernet RJ-45 connector, a thin coaxial cable, BNC connectors and thick coaxial, AUI interface, FDDI interfaces, ATM interfaces. And some network cards in order to apply to a wide range of application environments, provide two or more types of interface, if the card will also provide RJ-45, BNC interface or AUI interface.

TYPES OF NETWORK INTERFACE CARDS(NIC)

Computer outside the LAN connection is inserted through the mainframe as a network interface board (or a PCMCIA card ) is inserted in the notebook computer . The network interface board is also known as communications adapter or network adapter (adapter) or Network Interface Card NIC (Network Interface Card), but now more people are willing to use the simple name "card".

NIC: network standards

Network card: network standard local area network (LAN), the structure of three types: Ethernet (Ethernet), Token Ring, Token Ring, Token Bus (Token Bus), and three network backbone network fiber distributed data interface (FDDI). They follow the IEEE (the United States Association of Electrical Engineers) to develop standards of 802 at the beginning of a
total of 11 standards related to the LAN,

Disc loading mode (double-layer burning)

CD-ROM: What is the double-layer burning referred to the double-layer burning must first explain the specifications of the DVD disc. DVD disc to distinguish between single sided / double-layer and double-sided single / double-layer specifications according to records in accordance with the specifications, there will be a different capacity, depending on the capacity of the DVD is divided into four specifications, namely a DVD-5 DVD-9, the DVD-10 with DVD-l8.

What is a modular power supply?

What is a modular power supply? On a lot of senior players, they all know all-solid-state motherboard, tantalum capacitors graphics than the average motherboard, video card, however, whether the good news which, in fact, they can not tell. Power, too, a lot of players is not very clear why 80Plus perhaps modular power than ordinary power. Today, we would like to take this opportunity to discuss what is a modular power supply?
