FOR MORE INFORMATION

Hi Guyys! If have some questions in your mind, don't hesitate to ask. :)
Byeee! Finals is coming up. So, it will take some time before my next post. 

But don't expect that my next post will be posted here because I'll be posting some other stuff that teenagers could really ralate to. (exclude computers stuff) :)

Byeee! Hanggang sa muli! :D

GENERATIONS OF COMPUTER

Each Generation of Computer is designed based on the new technological development,  resulting in better, cheaper and smaller computers that are more powerful, faster and efficient than their predecessors.

1st Generation 

Vacuum Tubes

Machine language uses 0s and 1s for coding of the instructions. The first generation computers could solve one problem at a time. The computation time was in milliseconds. enormous in size and required a large room for installation. used vacuum tubes for circuitry and magnetic drums for memory.

Examples: UNIVersal Automatic Computer (UNIVAC), Electronic Numerical Integrator And Calculator (ENIAC), and Electronic Discrete Variable Automatic Computer (EDVAC).

2nd Generation 

Transistors

The instructions were written using the assembly language. The computation time was in microseconds. smaller in size compared to vacuum tubes.  used magnetic core technology for primary memory. They used magnetic tapes and magnetic disks for secondary storage.

Examples: PDP-8, IBM 1401 and CDC 1604. 

3rd Generation 

Integrated Circuits

The keyboard and the monitor were interfaced through the operating system. High-level languages were used extensively for programming, instead of machine language and assembly language. The computation time was in nanoseconds.  quite small compared to the second generation computers.  multiple transistors are placed on a silicon chip.

Examples: IBM 370, PDP 11.

4th Generation 

Microprocessors

Several new operating systems like the MS-DOS and MS-Windows developed during this time. This generation of computers supported Graphical User Interface (GUI).The computation time is in picoseconds. smaller than the computers of the previous generation. became widely available for commercial purposes.

Examples:  In 1981, IBM introduced the first computer for home use. In 1984, Apple introduced the Macintosh.

5th Generation

Artificial Intelligence

The goal of fifth generation computing is to develop computers that are capable of learning and self-organization. The fifth generation computers use Super Large Scale Integrated (SLSI) chips that are able to store millions of components on a single chip. These computers have large memory requirements. The fifth generation computers are based on Artificial Intelligence (AI). They try to simulate the human way of thinking and reasoning.

Artificial Intelligence such as Expert System (ES), Natural Language Processing (NLP), speech recognition, voice recognition, robotics, etc.

CONVERTING

BINARY TO DECIMAL

DECIMAL TO BINARY

BINARY TO HEXADECIMAL

DECIMAL - HEXADECIMAL - BINARY

IN CONVERTING DECIMAL TO HEXADECIMAL OR VICE VERSA, CONVERT IT FIRST TO BINARY THEN DO THE SAME PROCEDURE. 

Questions? Just ask. ;)

/GottaBeStrong

BINARY, DECIMAL, HEXADECIMAL.

Sick of Math? I SUPER FEEL YOU!

But be sick no more! Because when it comes to converting binary or decimal or hexadecimal, its just a piece of cake! I think... *Note: I am not good in Math tho. XD*

But before anything else, what is Binary? Decimal? Hexadecimal?

BINARY is a number that only includes ONES and ZEROS. A number that could be at any length. Also called as BASE-2.

DECIMAL is the numbers that we are used to seeing. It is consist of number from 0 to 9.Also called as BASE-10.

HEXADECIMAL uses 16 distinct symbols, the symbols 0-9 to represent the value of zero to nine and the letters, A to F, to represent the number 10-15. It is in the BASE-16.


If want to learn how to convert binary to decimal, binary to hexadecimal, decimal to hexadecimal or vice versa of any of those three. Just stay tune. :)

HARDWARE SPECS

Hardware Specification

- this dictates the limits and maximum capabilities of a hardware/device on a given criteria or unit of measurement.

Common Computer Hardware Specs Criteria

• Main memory
• CPU Clockrate and Wordsize
• Second memory
• Video Memory
• GPU
• Audio Adapter
• Wireless/LAN Adapter
• Display Adapter

System Requirements

- minimum hardware specs/conguration of a computer to be to run a particular computer software. (e.g. Operating System)

Any clarifications? Just speak up. :)

TYPES OF COMPUTER

There are 3 types of computer: the Hybrid, Analog, and the Digital Computer. 

The Digital computer still have sub-types namely: Super, Mainframe, Mini/Midrange, and Micro computer.

There's still 2 types of Micro computer, the Personal Computer (PC) and the Mobile devices such as our cellphone etc.



here are some pictures of a computer:

SUPER COMPUTER

MAINFRAME COMPUTER

MIDRANGE COMPUTER

PERSONAL COMPUTER

MOBILE DEVICES

COMPUTER SYSTEM

So what is Computer System?
It is one that is able to take a set of inputs, process them, and create a set of outputs.


The Computer System is made up 2 main parts: the Hardware and the Software.


The hardware is made up of 3 parts namely:

• Input and Output devices
• Central Processing Unit (CPU)
• Memory

While the software is made up of:

• Operating System (OS)
• Applications

You think the info is not enough or some details are incorrect? 

Then just message me through my gmail acc and answer you questions. If questions is not unswered, I'll ask our oh-so-reliable teacher Sir Tom. Hi Sir! *kaway-kaway*
