My Autobiography

I was born on a warm, sunny day in September 15 1988 in Davao City. I still Live in Davao City and I go to School at AMACC. I live with my Mother, Elena Braza, My Father. Lorenzo Braza, My 3 brothers, Gemar Braza, Steve Laurence Braza, and Laurence Braza. My Brothers Kinda sucks. Because they always tease me when i got home from school. But I Love my familyI always take it as a joke when my brothers tease me.

My name is Marlon Braza. I started school at when i was 6yrs old. I went through kindergarten in Gen. Baptist school. then I started my Elementary at Assumption College of Davao and while I was there. I was an Honor Student but it only last in Grade 2, at Grade 3 i never got an honor award since then. my attitude change. I did not study too well. And when Im in Highschool my grades are low because of my friends that ive influenced. And now Im at AMACC and taking the course of IT. Life means to me is friends and family who can trust with I am pretty much of a happy side of life but all teens I do have my "days of" That means I do have some bad days or Happy Days. in the year 2015 i will make 10 years since I graduate highschool. I think I would still live in Davao City. and I will take my second course in Ateneo De Davao University after I finish with my first course IT. and im quite comfortable with my living situation, meaning that I will fulfill my dreams and success what ever course that I take. As I said in the beggining I was born at Davao City and Ive live there for such a long time. I would like to go to other places that ive never been to. I hope you enjoy reading my Autobiography.

Computer Systems

1. Mother Board- A motherboard is the central or primary circuit board making up a complex electronic system, such as a modern computer.

2. CPU- is A central processing unit (CPU), or sometimes simply processor, is the component in a digital computer that interprets computer program instructions and processes data.

3.Power Supply- A computer power supply unit (Computer PSU), or Modular Power Supply Unit (MPS) is the component that supplies power to a computer.

4.Video Display Controller- that produces the output for the computer display. This will either be built into the motherboard or attached in its own separate slot (PCI, PCI-E or AGP), requiring a Graphics Card.

5. Keyboard- A computer keyboard is a peripheral partially modelled after the typewriter keyboard. Keyboards are designed for the input of text and characters and also to control the operation of a computer.

6. Mouse- In computing, a mouse (plural mice or mouses) functions as a pointing device by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of a small case, held under one of the user's hands, with one or more buttons. It sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features can add more control or dimensional input. The mouse's motion typically translates into the motion of a pointer on a display.

7. Application Software- Application software is a subclass of computer software that employs the capabilities of a computer directly to a task that the user wishes to perform. This should be contrasted with system software which is involved in integrating a computer's various capabilities, but typically does not directly apply them in the performance of tasks that benefit the user. In this context the term application refers to both the application software and its implementation.

Assignment

1. What is Computer Hardware and Software?

Computer hardware is the physical part of a computer, including the digital circuitry, as distinguished from the computer software that executes within the hardware. The hardware of a computer is infrequently changed, in comparison with software and data, which are "soft" in the sense that they are readily created, modified or erased on the computer.

Computer software, consisting of programs, enables a computer to perform specific tasks, as opposed to its physical components (hardware) which can only do the tasks they are mechanically designed for. The term includes application software such as word processors which perform productive tasks for users, system software such as operating systems, which interface with hardware to run the necessary services for user-interfaces and applications, and middleware which controls and co-ordinates distributed systems.
