*ULTIMATE FIST BUMP*

THANK YOU!!!

Sir Tom...Thank you for everything..

All that you have taught us have been helpful and very informative.

But of course nothing could top your jokes, hahahaha

Thank you sir for being a great.. no wait.. . stupend-- nope. .

a COOL and AWESOME Computer Science Teacher!! :) :D ;)

See you again when we're in Grade 9

More Quizzes? Yahoo!

Well this quarter we had a total of 3 quizzes and 1 Long Test.

Wanna know my Scores?

Quiz 1 = 11 out of 15

Quiz 2 = 7 out of 10

Quiz 3 = 12 out of 15
Long Test = 15 out of 24

Yaaay passed all of 'em!!! Although I passed, i honestly had difficulties this quarter with the quizzes. That's why my scores aren't that high. But that's still okay right?

Installing Operating System (OS)

How to install Windows 7 OS:

here are OTHER examples of Operating Systems:

• LINUX

• MAC OS

• UNIX

• SOLARIS

Computer System Unit Components

These Components are:

• Motherboard
• Power Box
• RAM (Main Memory)

Generations of Computers

The Generations are designed based on technological development

1st Generation-Vacuum Tubes

2nd Generation-Transistors

3rd Generation-Integrated Circuits

4th Generation-Microprocessors

5th Generation-Artificial Intelligence

Machine Cycle + Networking

Machine Cycle - also called as processor cycle. The basic operation performed by a CPU

Sequence:

Fetch > Decode > Execute > Store

Here's a video for you to learn more:

Networking

Network- allows computer systems to exchange information

1. LAN – Local Area Network
2. MAN - Metropolitan Area Network
3. WAN - Wide Area Network

Conversion

Data Conversions

Binary - Decimal

Decimal - Binary

Binary - Hexa-decimal

Hexa-decimal - Binary

Decimal - Hexa-decimal

Hexa-decimal - Decimal

Data Representation

 Digitizing - process of inputting files then converting them into their respective binary form for the computer to analyze

Basic Devices for Storing Binary Info:

• Electronic
• Magnetic
• Optical

More Info: Bit is the smallest unit of data in a system

Byte is equal to 8 bits = 1 character

Data Cycle

The cycle is composed of:

• Input Device
• Main Memory (RAM)
• Central Processing Unit (CPU)
• Output Device

Data is plugged in with the input device then the RAM stores it. Next, the data goes to the CPU so that it will be processed and then goes back to the Main Memory. Lastly, data goes out via output device

Software

Software refers to a program which instructs the computer system on what to do

2 Types of Software:

1. System Software- manages,maintains,and controls computer resources
2. Application Software-performs specific personal, business, scientific processing tasks

Under System Software:

• System Management Software- Operating System (OS)
• System Development Programs- Compilers

Platforms- defined by a processor and an operating system

Hardware Specs

Hardware Specs or Hardware Specifications are guidelines used for knowing the limitations of a certain hardware device or gadget.

Here are the Basic Computer Hardware Specs:

• Main Memory   

• CPU Clockrate and Wordsize 

• Secondary Memory 

• Video Memory 

• GPU 

• Audio Adapter 

• Wireless/LAN Adapter 

• Display Adapter

The Final Countdown

4th Quarter = Last Chapter = The END

The end of the school year is nearing and also Summer but...

I CAN'T SMILE!

Why? because that means no more school, no more seeing your fiends, no more seeing your school, and most of all no COMPUTER SCIENCE!

But anyways...this quarter will be all about COMPUTERS/COMPUTER SYSTEM. 
Well I'll just hope this quarter will be worth it.....

Computer System

A Computer System is basically a combination of hardware and software. It processes inputs and creates a set of outputs.

There are 3 main types of Computers:

• Digital
• Analog
• Hybrid

And under DIGITAL there are 4:

1. Micro Computer
2. Mini Computer
3. Mainframe Computer
4. Super Computer

Such a Random Quarter

Aw man, another segment of the school year has just passed.

Why does time have to fly so FAST??!!

Well I have been taught a lot this quarter, there have been stuff that I thought I knew but didn't.

And I can therefore say that this was an EXCELlent quarter 

hehehe. I had a load of fun and I guess my performance was pretty good.

PLUS I got the chance to ask Sir Tom two Random Questions a day.

See how much fun that is? haha

Then i guess this is goodbye fellas, 'til the next chapter of my Journey!

Oh and NEVER FORGET

2nd and Final Test

This time our Long Test was a Practical.

It was easy for me because it was just about charts and macros.

So let's take a look at what I did,

Charts portion

Well since the macros portion was just a set of commands, it's a blank page, awwwww

Macros

This is our final topic for the quarter...

I know.... oh well

At first all of us had no idea what macros was, I honestly thought it was really complicated but fortunately it wasn't

Macros is used to create your own shortcuts in for something that you often do in excel. Instead of doing your 'ritual' all over again, with macros you'll just press a few keys and your work is done.

First Long Test

I actually had some difficulty in answering the test, 

but luckily I passed. 

Let's say the passing score is 15/25 

I got 17/25.

A Close call right?

#soclose #rollerblading #fail #lol

Quizzes? Oh Man...

Hold on there, there's nothing to worry.

I passed all of them!

And we had a total of only 2 quizzes this first half of the second semester. I got 8/10 on the first then 7/10 on the second.

Lab Exercises and Activities

Well I guess Computer Science isn't fun if there aren't practical exams or hands-on activities.

Sooo we had a lot of them this Quarter.

Hell yeah! right? Well here are Sneak peeks of my outputs...
