Active-Matrix VS Passive-Matrix Display

Passive-Matrix LCDs were standard in most early laptops (although a few used plasma displays) and the original Nintendo Game Boy until the mid-1990s, when color active-matrix became standard on all laptops. Passive-matrix LCDs are still used today for applications less demanding than laptops and TVs. In particular, these are used on portable devices where less information content needs to be displayed, lowest power consumption (no backlight) and low cost are desired, and/or readability in direct sunlight is needed.

Active-Matrix LCDs  is a type of flat panel display, currently the overwhelming choice of notebook computer manufacturers, due to low weight, very good image quality, wide color and response time. Whereas a passive-matrix display uses a simple conductive grid to deliver current to the liquid crystals in the target area, an active-matrix display uses a grid of transistors and capacitors with the ability to hold a charge for a limited period of time.

World Book Day ! Roses~

Today, there's an event going on in my college..

It is the 23rd of April, They named it "The World Book Days"


From what I heard, UNESCO declared 23rd of April the World Book Days.
This symbolic date for universal literature also marks the passing away of Miguel de Carvantes and William Shakespeare on the same day in 1616.


In the Spanish region of Catalonia, on 23rd of April, a rose is exchanged for each book received.

Mouse OpeRation 3ple Clicking

Double clicking refers to clicking (and, naturally, releasing) a button (often the primary one) twice. Software recognizes both clicks, and if the second occurs within a short time, the action is recognized as a double click.
If the second click is made after the time expires it is considered to be a new, single click. Most modern operating systems and mice drivers allow a user to change the speed of a double click, along with an easy way to test the setting. Some software recognize three or more clicks (triple click), such as progressively selecting a word, sentence, or paragraph in a word processor text page as more clicks are given in a sequence.

Triple clicking in Safari highlights the whole line, including the line break at the end. Firefox stops short of the line break.

Multi Core Processor

A multi-core processor is a single computing component with two or more independent actual processors (called "cores"), which are the units that read and execute program instructions.The instructions are ordinary CPU instructions such as add, move data, and branch, but the multiple cores can run multiple instructions at the same time, increasing overall speed for programs amenable to parallel computing.Manufacturers typically integrate the cores onto a single integrated circuit die (known as a chip multiprocessor or CMP), or onto multiple dies in a single chip package.


A dual-core processor has two cores (e.g. AMD Phenom II X2, Intel Core Duo), a quad-core processor contains four cores (e.g. AMD Phenom II X4, Intel's quad-core processors, see i3,i5, and i7 at Intel Core), a hexa-core processor contains six cores (e.g. AMD Phenom II X6, Intel Core i7 Extreme Edition 980X), an octa-core processor contains eight cores (e.g. Intel Xeon E7-2820, AMD FX-8150).A multi-core processor implements multiprocessing in a single physical package.Designers may couple cores in a multi-core device tightly or loosely. For example, cores may or may not share caches, and they may implement message passing or shared memory inter-core communication methods. Common network topologies to interconnect cores include bus, ring, two-dimensional mesh, and crossbar. Homogeneous multi-core systems include only identical cores,heterogeneous multi-core systems have cores that are not identical. Just as with single-processor systems, cores in multi-core systems may implement architectures such as superscalar, VLIW, vector processing, SIMD, or multithreading.

Special College Thursday

This is the second week since I have enrolled into the HELP CAT. The college life that I have been going through now is amazing and fun. The lecturers in our class are unexpectedly friendly and there are a lot of kindful people here that are willing to lend you a hand. Our studies has been started going on as soon as the day we finished our orientation, everything look normal to me until we finished our first class on Thursday. When we finished our first class on Thursday, the head of I.T Department, Mr.John David announced that there will be a meeting after our last class. Right after we are done with our last class, we gathered at the theatre hall. Apparently, we have been tricked to the dance studio by Mr.John. He said that we will be having Extra Curriculum Activities(ECA) every thursday. Every student's reaction was nervous and surprised. Their legs were shaking at first, but right after the activities started, they started to calm down and have some fun. I didn't know that the IT students have to participate in dancing class too...
