Chapter 1.1.1 and 1.1.2 Summary by Mariana Angulo https://padlet.com/mangulo1247/f3jffp872fld en-us 2016-08-11 17:40:28 UTC 2026-02-26 05:09:15 UTC hello@padlet.com Bianett Rodríguez López rdzbianett https://padlet.com/mangulo1247/f3jffp872fld/wish/118060602 A01283479

ASCII
Is the American Standard Code for Information Interchange, it is represented by 128 characters and has a combination of 8 bits. It is for case letters, punctuation symbols and numbers.

UNICODE
A character code to represent the alphabet with multiple languages, for example: Chinese, Japanese and Korean, it uses approximately 16 bits with a capacity of storage  of 65000 representations. The stored file contains a file header which indicates the category of the content so the computer can storage otherwise, there will not be a storehouse.

Now a days the units of a disk of a computer is 500 GB and the transmission of Internet is 11 Mb.

They show the process and information of all users. Some examples include: The monitor which displays the work the user is doing, some of the types of screens are LED screens LCD(liquid crystal display) and Plasma screens. The Printers pass the data you created or found onto paper. There are many types of printers but the one that has the greatest quality work is the Laser printer. Besides the speaker that the computer has already included, for better quality sound, you should use either earphones or speakers . Multifunctional Peripheral devices are machines that can perform several tasks such as printing, coping scanning etc. They are also very accessible.
 
Storage devices are the components that store all the data in one or several computers. Some of them like the USB and the CD are portable devices. There are many ways a storage can be, mainly they are magnetic(magnetizing), optical (laser) or of a solid state (Fowler-Nordheim).
 
The system unit is the most essential part of a computer. It has a microprocessor which’s task is to in detail all the data the computer has.

When they relate, they help people of organizations to get information to be communicated for others to make the best decisions 

Information systems have input, processing, output, and storages functions. That means that the users enter the data that is processed to provide information.

Reflect and imagine that in the same way computers receive data through the different input devices, then, the microcompresor analyzes them in order to transform them into content that is presented through output devices. 

Computers work with a binary system because there are only two values, and they work with base 2. Numbers 2 and up do not exist, to represent other numbers it is used an extra 0 on the right. Each 1 or 0 is called a bit, and it is the smallest data unit. A series of 8 bit is a byte, and is used to represent information.

The software refers to the programs that are instructions that step by step the device elaborates while the hardware is in where the mechanical, electrical, and electronic components are store. The components are called input, output, system units and storage devices

The input devices allow data and instructions enters the computer. The next two component are

the most important but the rest of them have also an important role and use:

1.- Keyboard: QWERTY design. Contains also several keys that are used for specific functions as number, arrows, page up and down, etc.

2.- Pointer: also know as mouse. It is used to controlled the cursor. There are more format besides the mouse, there are track pads, pointing sticks, joystick, etc.

3.- Microphone: Audio input that can be previously installed in the computer but also can be adapted externally on a port. For recording is necessary to use a software in order to saved on a disk file.

4.- Video Camara: Best know as a WebCam. Cameras just as microphones requires a conversation from analog signals to digital signals or versa (digitalization).

5- Digital cameras: Captures images electronically.

6.- Scanners: Photosensitive. It transforms images or text to into formats in order to send it to the computer and edit it.

7.- Biometric devices: They read a characteristic of a Person to compared to a previously saved
code or identity. Can be recognized by facial, voice, iris or retina.

8.- Sensors: Measures different type of data that are send to the computer to be processed. Some examples are the GPS in you cellphone or the utilities for workout that measures blood pressure, calories, etc.

9.- Digitized tablets: Are used to create art. It has a smart pen that regulates the lines. It is required to be connected to an USB interface or to Bluetooth.]]> 2016-08-12 13:17:17 UTC https://padlet.com/mangulo1247/f3jffp872fld/wish/118115135
