Hi Sir

Hi sir,

Uhm... It's not like I'm being a drama Queen or all, I mean, we will be seeing each other next year naman e. I just feel like writing you a letter because you know-- obviously-- that you're the coolest CS 1 teacher I've ever met (not that I met all the CS teachers) Even though I wasn't deserving, you gave me grades of 1.5 and 1.75. I sucked during the 2nd and 3rd quarter yet you gave me a 1.75. I really thank you for that, Sir. I really expected a grade of dos or lower, really. I also thank you for understanding us. Teachers like you are rare. I just hope you could be our Math teacher. Haha.

Anyways, thanks again sir. Hope you'll be our teacher again in CS 3 and 4 ^_^

Yours truly,

Ms. Photogenic ♥

SOURCES (a very important post)

In every blog that I make, I wouldn't forget the SOURCES. I mean, c'mon! I'm not THAT bad to commit plagiarism. Okay. Okay. So these are the sources that I should thank.

Fifth Generation (Artificial Intelligence)

Fifth Generation (Present and Beyond) Artificial Intelligence

Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.

Fourth Generation (Microprocessors)

Fourth Generation (1971-Present) Microprocessors

The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central processing unit and memory to input/output controls—on a single chip.

In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh. Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors.

As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.

Third Generation (Integrated Circuit)

Third Generation (1964-1971) Integrated Circuits

The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.

Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.

Second Generation (Transistors)

Second Generation (1956-1963) Transistors

Transistors replaced vacuum tubes and ushered in the second generation of compuJordanters. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output.

Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology.

The first computers of this generation were developed for the atomic energy industry.

First Generation (Vacuum Tubes)

First Generation (1940-1956) Vacuum Tubes

The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.

First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.

The UNIVAC and ENIAC computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951.

Generations of Computers

Out of the topics I promised you guys, I chose this topic because it was the topic I can remember most. I don't even know why. Maybe it's because  reality hit me right in the feels? I mean... Come on Aimee! It's already fourth qua! Just ignore all those ideas invading your brain and just listen to the coolest Comp. Sci. teacher ever! Anyway, we shall start.

••°°••°°••°°••°°••°°••°°••°°••°°••°°••°°••°°

Generations of Miracles-- I mean Computers is the just the same with the history of computer devices. Each of the five generations of computers is characterized by a major technological  development that fundamentally changed the way computers operate, resulting resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable computing devices.

••°°••°°••°°••°°••°°••°°••°°••°°••°°••°°••°°

Now that we had learnt the meaning of Generations of Computers, we shall begin our journey.

MACROS

MACROS

Macros is the recording of what you do on your worksheet and making a shortcut out of it doing the same thing. It always starts with Ctrl+ 

STEP BY STEP PROCESS

1. Go to View and click Macros at the left part.

2. Then click "Record Macro"

3. Fill in your Macro name and the shortcut key. And then click okay.

4. When you're done you can always stop the recording by clicking on the little blue square on the lower left corner of your screen.

5. Now you're ready to go. Go on push the keys on your keyboard. You can now use the shortcut key you just filled in.

Cell and Range

CELL and RANGE




• A7 – single cell
• A7,A14 – cell A7 and cell A14
• A7:A14 – range from A7 to A14 (same col)
• A7:Z7 – range from A7 to Z7 (same row)
• A7:Z17 – range from columns A to Z and
rows 10 through 20

TIPS

TIPS

Of course, we wouldn't want to have a hard time. People will always find different ways for them to be able to rush things. And these are shortcuts.

When we say "shortcuts" Ctrl+, Alt+, Shift+ and many more always come to our minds. Well, you know what? We are absolutely correct!

Microsoft Excel has its own shortcuts for our convenience.

Here are some of them:

1. Alt+Enter it helps entering a new line of space inside a cell without disturbing other cells. It's counterpart in Facebook chat is "Shift+Enter".
2. Check "Advanced Options" you can change your settings here.
3. Ctrl+; or Ctrl+Shift+; the keys for our beloved shortcuts
4. Columns with uniform widths highlight the columns you need and then stretch one. Results will show that the ones you highlighted are now in uniform widths.
5. Merge Cells Highlight your cells then go to Home (not literally). Click Merge & Center  and them VIOLA! You got your merged cell =))

• 
• There are more tips we should/could learn. To make our daily Excel stuffs be easy =D

Columns and Rows

COLUMNS and ROWS name a cell. They help each other to form a cell's name. Just like what I've noted in my post "Name Box", a cell's name came from the cell's column "F" and the cell's row "11".

"F 11" is its name =))

Cells

CELLS are the little boxes/squares/rectangles formed by grids. There you can put any data you want.

DIFFERENCE BETWEEN ACTIVE CELLS AND CELLS

• An active cell is the one you're currently using.
• While the cell (just cell) is the one there.. just hanging, waiting to be used.

Formula Bar

A FORMULA BAR shows the data the selected cell contains.You click on the cell and the whole data shows up on the upper part of the sheet... the Formula Bar.

Note: You can also edit your cell using the Formula Bar

Name Box

The NAME BOX contains a cell's selected reference number- its position on the sheet. It shows the name of whatever cell you select or click inside the sheet. It always starts with a letter and ends with digits.

Note: The name of your selected cell is based on its column and row. For example, that photo over there. The Name Box contains "D7". "D" is the cell's column while "7" is its row.

Parts and Functions

This is a WORKSHEET.A worksheet is a page full of grids that contains all the data you put in it. We call the Excel File a Workbook. 

These are the labeled parts of a worksheet.

It's All About Microsoft Excel

Microsoft Excel is a spreadsheet application developed by Microsoft for Microsoft Windows and Mac OS. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications. It has been a very widely applied spreadsheet for these platforms, especially since version 5 in 1993, and it has replaced Lotus 1-2-3 as the industry standard for spreadsheets. Excel forms part of Microsoft Office.
