COMPUTER

Today, I want to discuss we all of you about COMPUTER.First of all,what is Computer?For sure most of you what computer it is.Computer is something that can less human energy and something that easier for man kind to settle down their project or work.
However,the truth definition of computer is :
A system of interconnected computers that share a central storage system and various peripheral devices such as a printers, scanners, or routers. Each computer connected to the system can operate independently, but has the ability to communicate with other external devices and computers.

Parts Of Computer

If you use a desktop computer, you might already know that there isn't any single part called the "computer." A computer is really a system of many parts working together. The physical parts, which you can see and touch, are collectively called hardware. (Software, on the other hand, refers to the instructions, or programs, that tell the hardware what to do.)

The illustration below shows the most common hardware in a desktop computer system. Your system may look a little different, but it probably has most of these parts. A laptop computer has similar parts but combines them into a single notebook-sized package.

System Unit

The system unit is the core of a computer system. Usually it's a rectangular box placed on or underneath your desk. Inside this box are many electronic components that process information. The most important of these components is the central processing unit (CPU), or microprocessor, which acts as the "brain" of your computer. Another component israndom access memory (RAM), which temporarily stores information that the CPU uses while the computer is on. The information stored in RAM is erased when the computer is turned off.

Almost every other part of your computer connects to the system unit using cables. The cables plug into specific ports (openings), typically on the back of the system unit. Hardware that is not part of the system unit is sometimes called a peripheral device ordevice.

Keyboard

A keyboard is used mainly for typing text into your computer. Like the keyboard on a typewriter, it has keys for letters and numbers, but it also has special keys:

• The function keys, found on the top row, perform different functions depending on where they are used.
• The numeric keypad, located on the right side of most keyboards, allows you to enter numbers quickly.
• The navigation keys, such as the arrow keys, allow you to move your position within a document or webpage.

Monitor

A monitor displays information in visual form, using text and graphics. The portion of the monitor that displays the information is called the screen. Like a television screen, a computer screen can show still or moving pictures.

There are two basic types of monitors: CRT (cathode ray tube) monitors and LCD (liquid crystal display) monitors. Both types produce sharp images, but LCD monitors have the advantage of being much thinner and lighter. CRT monitors, however, are generally more affordable.

Speakers

Speakers are used to play sound. They may be built into the system unit or connected with cables. Speakers allow you to listen to music and hear sound effects from your computer.

OUR ASSESMENT WITH SMK AMINUDDIN BAKI

Assalamualaikum and hai everyone...
For your information,we have done with our second assignment which is Assesment in school that related to the network of the school.

Due to date,my group and I choose SMK Aminuddin Baki in order to complete this assignment.Before that,let's me introduce my group.There are :

1. Nurul Ainina binti Kamid
2. Nursyidatul Najah binti Mohd Rawi
3. Syuhada Fatieha binti Bachik

Our assesment is on 19 April 2012.For your addition information,we choose school as our assesment because we want to related on what we have study and we want to look the real things that apply.Not just theory like what we study in the class.

The others point on what we do at the school will be presented at the lecture class.

Till we meet again..  :)

 

COMPUTER CHIPS

Computer Chips May Repair Nerve...

Edinburgh University has developed a technique, which allows neurons to grow in fine, detailed patterns on the surface of tiny computer chips.

Neurons are the basic cells of the human nervous system.

The scientists said the development may eventually enable chips to replace damaged nerve or muscle fibres.

They also said the development could possibly be used in the development of prosthetics in the future.

During the chip manufacturing process, the scientists printed patterns on the smooth silicon surface.

The chip was then dipped in a patented mixture of proteins, and neurons grew along the patterns on the surface.

The technique also works with stem cells.

It is hoped the method will eventually enable any type of tissue to be grown on a tailor-made pathway and implanted as prosthetic tissue in the body.

Professor Alan Murray, head of Edinburgh University's School of Engineering and Electronics, who led the research, said: "This is a small but important step on the path towards the long-term goal of many scientists and medical experts - to develop surgical implants using silicon chips.

"We can now make silicon chips with circuitry as well as pathways where cells can grow in the body.

"One of the areas this could be used in is prosthetics - if we can cause cells from damaged tissues to grow where we want.

"It is going towards the realms of science fiction - there is a definite Incredible Hulk feel about it."

He added: "We also hope that, rather sooner than this, the technique will allow better methods of drug discovery and reduce the need for animal testing, as new medicines could be tested on chips rather than in live creatures."

The research was funded by the Engineering and Physical Sciences Research Council.
