EXPANSION SLOTS IN MOTHERBOARD

EXPANSION SLOTS IN MOTHERBOARD  Friends today i am going to share my knowledge and understanding of the expansion slots. So lets begin with our topic. Expansion slots are used to provide additional properties for carrying the computation task such as additional video, audio and sound, advanced graphics and Ethernet.   So lets begin with our knowledge hunting. I will start by AGP expansion slots. AGP AGP stands for ACCELARATED GRAPHICS PORT.  AGP was introduced with high speed 3D graphics display in 1996.  It is used for older graphics card types which is discontinued by PCI EX16 graphics port in 2005.   These were kernel version of AGP most of the brand in 1.5 volt DC.  AGP 1x channel and 66MHZ clock speed resulting a data table of 266 MBPS.   AGP 2x, 4x ,8x specification multiply MHZ clock to produce increase throughput. AGP 8x produces effective clock frequency of 533 MHZ resulting a throughput of 2 GBPS (2133MHZ) resulting a throughput of over a 32 bit channel. PCI PCI  stands for P

MONITORS: A COMPUTER PART

Folks today i am going to say something about an output device called monitor.   As maximum people know about monitors so i am going to write few things about monitor much of the information you know but i am going to say some few words hence please be with me. Monitor is a primary output device.   It displays all current process application and data i.e. Running inside a computer system.   A standard monitor uses an analog vga interface, which plugs into a tp15 vga connector to a mother board.   There are two types of monitor technology available to the market. CATHODE RAY TUBE (CRT MONITOR) This monitor is fading in popularity but still in widespread use with older computer systems.   It is analog standard monitor a crt uses a picture tube that was used in older tube based tv sets.   The narrow end of the picture tube contains an electron gun it emits 3 electron beams one each for red, green and blue light.   The front end of the picture tube is coated with phos

RAM PROPERTIES Friends in the last post i tried to explain the different types of ram as well as given the details of its similarities now i am going to show you how the properties of ram can be judged . SO LET US BEGIN. SINGLE SIDED VS DOUBLE SIDED DIMMS or DUAL INLINE MEMORY MODULE whatever you call are often referred to as single chip or double sided to describe whether the chips are located on one or both of the modules printed circuit board . However these terms may cause confusion or distract you from the topic, as the physical layout of the chips does not necessarily relate to how they are logically organized or accessed in whatever terms you are told. ERROR CORECTING CODE MEMORY (ECC MEMORY) An ERROR CORRECTING CODE (or ECC) whatever general public says  could be a   kind of  computer data storage  which will  detect  and proper  the more common  types of  internal data corruption in simple words with firmness and boldness. Most computers or workstati

ALL ABOUT LASER PRINTER

ALL ABOUT LASER PRINTER This printer is also known as page printer because they receive their print job one page at a type.   There are two major types of laser printer 1)       The first use a laser to scan the image on two a organic photo conductive drum (OPC) 2)       The second use an array of led to create the image on the drum.   Xerox invented this printer in 1971 but the first laser printer was introduced y hp in 1984. BASIC COMPONENTS Tonner cartridge :Tonner is a black carbon substance mixed with polyster resin to make it flow better and iron oxide particles to make it sensitive to electrical charge.   Tonner contain a medium called developer which carries the tonner until it is used by the EP(Electro photography) process. The tonner also contains the opc drum.   The drum is coated with a photo sensitive material that hold a static charge unless it is exposed to light.   The drum also contains a cleaning blade known as doctor blade. That continuousl

INTEGRATED CIRCUITS WITH A SOFTWARICAL TWIST

LOGICAL DESIGN OF FUNCTION OF INTEGRATED CIRCUITS A binary variable or called as two value variables can take the value of 0 or 1.  A Boolean functions or named as two variable function is an expression formed with binary variables, the two binary operators OR and AND, the unary operator NOT, parenthesis, and equal sign.  For a given value of the variables to made it as good and thorough, the function can be either 0 or 1.  Consider, for example, the Boolean function:                                                  F1 = xyz’ The function as shown above F1 is equal to 1 if x = 1 and y = 1 and z’ =  1; otherwise F1 = 0.  The above is an example of a Boolean functions represented as an algebraic expression.  A Boolean function may be represented in a truth table.  To represent a function of a truth table we need a list of 2^n combination of 1s and 0s of the n binary variables and a column showing the combinations for a function equal to 0 or 1. As shown in Table below, th
