The END never ends...

So, basically, I was not supposed to post another one here on blogger. But, since this is already the last quarter, and I believe that this could be a chance for me to say something. First of all, this could be a long post... because I really have to blurt out everything. So, to get started, I will have a simple "Thank You" for our cool teacher, Sir Tom. Thank you, Sir, because you were the one who taught us that there are no limits when we believe that we can do anything. Thank you for those times that you still taught us everything that we needed to know. Thank you for always being there for us despite our flaws and being reckless. We may not be those perfect students, but we know that you are the awesomest of the awesome. Thank you for all the knowledge that you shared to us, all the long tests (that we failed at.), all the practical exams, etc. 

I know that this is kind of madrama but I do believe that these things were true. If it only was not because of him, we won't have these things that we know now. 

"Teachers are our heroes."

An operating system (OS) is software that manages computer hardware and software resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function.

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware,[1][2] although the application code is usually executed directly by the hardware and frequently makes a system call to an OS function or be interrupted by it. Operating systems can be found on many devices that contain a computer—from cellular phones and video game consoles to supercomputers and web servers.

Examples of popular modern operating systems include Android, BSD, iOS, Linux, OS X, QNX, Microsoft Windows,[3] Windows Phone, and IBM z/OS. All these examples, except Windows, Windows Phone and z/OS, share roots in UNIX.

Artists once Again

Oh, Yes! We are artists once again, going through our SHOOTING. Wait, what? You mean, TROUBLESHOOTING? Aw, man! ~_~

Moving on, have you ever experienced problems regarding your computer? Well, the solutions there are so simple. 

  • Make sure all components of the affected computer system (the monitor, the CPU, the printer, etc.) are switched on and receiving power. If there is a power problem, try performing a Power Check.  
  • Check to see if all cables are firmly connected to the device. If not, fit it snugly in place.
  • Reboot or restart your computer.
  • Check the Device Manager of your computer.
  • Check the power cord to make sure that it is not damaged.
  • Test the equipment and electrical outlet.
  • If you find or suspect that the power cord to your computer or monitor has been damaged or severed, DO NOT ATTEMPT to f!x this type of problem yourself. >:D

Sa Susunod na Henerasyon

Each generation of computer is designed based on a new technological development, resulting in better, cheaper and smaller computers that are more powerful, faster and efficient than their predecessors.
Goel, A. (2010). Computer Fundamentals. India: Pearson Education India.

The 1st Generation are the VACUUM TUBES:

The 2nd Generation are the TRANSISTORS:


The 3rd Generation are the INTEGRATED CIRCUITS:


The 4th Generation are the MICROPROCESSORS:


The 5th Generation is known to be ARTIFICIAL INTELLIGENCE:


Then, I realized that in a span of 50 years, there are already many changes that happened in the field of technology. Therefore, we should be more creative and believe that there are no limits because, who knows? Maybe we are the ones who could make the most record-breaking gadgets of all time. Kaya, sa susunod na henerasyon, madami pa kayong maaabot.

Nosebleed? That only means 'Machine Cycle+Networking' when converted to Spanish.. :3

A machine cycle, also called a processor cycle or a instruction cycle, is the basic operation performed by a central processing unit (CPU). A CPU is the main logic unit of a computer. There are four steps.  Fetch - Retrieve an instruction from the memory. Decode - Translate the retrieved instruction into a series of computer commands. Execute - Execute the computer commands. Store - Write the results back in memory.  

Now, let's move on to networking. Network -  is a group of two or more computer systems linked together.  Packet -  is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network. There are also different types of network such as LAN, WAN (two,three,four xD), MAN, WLAN, PAN, SAN and CAN (can't xD)

Data Transmission- the physical transfer of data over communication channel or medium such as copper wires, optical fibers, wireless channel and storage devices.  Data are represented as electromagnetic signals such as an electrical voltage, radiowave, microwave or infrared signal.

Converting... what?!

How to convert:


Binary to Decimal:

Decimal to Binary:

Binary to Hexadecimal:

Hexadecimal to Binary:

Decimal to Hexadecimal: 


Hexadecimal to Decimal:


Too many videos right? But they simply summarize it all up.

Intro to Binary,Decimal and Hexadecimal

A binary or base-2 is a number that only contains 1 and 0. As we all know, "bi" means two. In the word binary, it derives its name from the fact that the digits in a "Binary" number can only have two possible values, 0 or 1. It is also called "base-2" based on the fact that the column values are the powers of 2.  (i.e. 2^0  2^1  2^2  2^3  2^4  2^5  etc. )  
Some of these examples are: 0, 1, 10, 01, 1010, 00001111,etc. 

A decimal or base-10 is simply the numbers that we see. Decimal numbers consist of the digits from 0 (zero) through 9. The following are examples of decimal numbers  
 3  , 76 , 15 , 32423234 , 890 , 53.

A hexadecimal or base-16 is basically a mixture of numbers and letters. For example, ABC, 3DF, 12E, etc.

Cycle and Data Representation

In this post, I will share to you two of the lessons that Sir Tom taught us.

They say, "Life is a cycle". Well, in the world of computers, they also have a cycle. 


It all starts with the INPUT DEVICE. This gives instructions and data to the MEMORY(RAM). The CENTRAL PROCESSING UNIT gives data to the memory while in return, the memory gives instructions and data for the Central Processing Unit to analyze. Going back to memory, it gives out the results to the OUTPUT DEVICE.

I think you get this already xD

The second topic is about data representation which is about bits and bytes. Digitizating is the process of taking photos, videos and other visual materials to smaller pieces called binary so that the data can be easily processed by the computer. There are three common basic technologies for storing binary information.  They are EMO. Electronic, Magnetic and Optical 

Also, 1 byte = 8 bits 1 kilobyte (K / KB)= 1,024 bytes 1 megabyte (M / MB)=1,048,576 bytes 1 gigabyte (G / GB) = 1,073,741,824 bytes 1 terabyte (T / TB)= 1,099,511,627,776 bytes 

Where's ware?

Ever thought of a day where our minds can be controlled by something or someone else? Well, I think that that is kind of creepy. But, in the world of computers, that happens already. They have a thing inside of them or program that tells them what to do. It provides instructions that the CPU will carry out. Can you guess what it is? A software. 

There are two kinds of software. System Software – programs that take control of the PC on start-up, and then play a central role in everything that happens within a computer system by managing, maintaining, and controlling computer resources. Application Software – designed and created to perform specific personal, business, scientific processing tasks.

 *Compilers - Softwares used to create softwares through programming.  


PC Platforms 

Platform is defined by a processor and an operating system. Software created to run a specific platform won’t run on other platforms.    

Most personal computer users choose the Wintel platform, which combines one of the Microsoft Windows operating system with an Intel-compatible processor.   

Modern Wintel platforms, such as Windows XP,

Vista

 and Windows 7,

 are backward compatible, allowing programs written for earlier Microsoft platforms to be run on modern systems.  

Before choosing a platform, consider the following:
• Availability of appropriate commercial applications software for the platforms.
• Compatibility of platform with existing hardware, software, and expertise

System and Specs

A computer system is one that is able to take a set of inputs, process them and create a set of outputs. This is done by a combination of hardware and software. There has also been other types of computers just like: 

Analog Computer

Mainframe Computers

Mini Computers

Super Computers

Artificial Intelligence

COOL,right? These are new technologies that could help us everyday.

In addition, we also have Hardware Specs. Hardware Specs or Hardware Specifications dictate the limits and maximum capability of a hardware/device depending on a given criteria or unit of measurement. Some Common Computer Hardware Specs Criteria are: 
• Main Memory 
• CPU Clockrate and Wordsize 
• Secondary Memory 
• Video Memory   
• GPU 
• Audio Adapter 
• Wireless/LAN Adapter 
• Display Adapter 

System Requirements is the minimum hardware specs/configuration of a computer system to be able to run a particular computer software (e.g. Operating System) 

 “The hardware specifications of a computer will vary depending on what an individual user will be doing with it. A person that wants to use their computer for graphically intense games or video editing will need a totally different configuration than somebody that just wants to browse the Internet and type word documents.”

Being in PSHS was one of the most uplifting things that had ever happened in my life. Because of choosing to study in this institution, I probably already heard many oppurtunities knocking on my door. Now, as I am about to finish my first year in high school, I am greatly grateful that I learned and experienced so many new things-- specially in COMPUTER SCIENCE 1

Well, that was overly dramatic. 

Anyways, Hello again! So as I was saying, this is the Fourth Quarter (finally)... and, I am about to share to you chunks of knowledge, truckloads of ideas, and heaps of facts. Stay tuned! ;)
