Meaning of Data
Data as the name implies is an instruction or any information that can be entered into a computer system. These information are entered into the computer system by the use of inpute devices like the keyboard use in typing, the mouse used for moving the cursor and also clicking, the mouth piece used for talking I.e. making your voice louder to the audience, cameras used in taking photographs and capturing videos, etc
     
There are dufferent types of data and they are:
1.  Alphabetical Data
2. Numerical Data
3. Alphanumerical Data
4. Voice Data
5. Visual Data

1.
Alphabetical data are letters of the alphabet -A-Z that is entered into the computer system using the keyboard. They could be either small letters or capital letters. Examples are A, B, h, etc.



2.

Numerical data are numbers that are typed or entered into the computer system. Numbers represent quantities and they are arithmetical and quantitative data that can be calculated. Examples are 0-9


3.

Alphanumeric data comprises of both Alphabetical (LETTERS) and Numerical (NUMBERS) data which are simultaneously entered into the computer system using the keyboard. Examples are 0-9 & A-Z. They can be mixed together in writings.


4.

Voice data collection, also sometimes referred to as speech data collection, involves gathering and measuring audio data. This data can be obtained from a variety of sources and is used by machines to understand and process audio input, making virtual assistants and other AI programs more user friendly.


5.



Data visualization is the graphical representation of information and data. By using visual elements like charts, graphs, and maps, data visualization tools provide an accessible way to see and understand trends, outliers, and patterns in data.

A Computer is defined as an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program. CHARACTERISTICS OF COMPUTER Characteristics of computer are those features, qualities, and properties displayed by a computer. Any digital Computer carry out these four characteristics below: 1. Takes Data as input 2. Stores the data/instructions in its memory 3. Process the data to become a useful information 4. Takes out data as output ADVANTAGES OF COMPUTERS. Here below are the advantages of Computers: 1. High Speed 2. Accuracy 3. Versatility 4. Reliability 5. Automation 1. High Speed:  Computer is a high-speed device. It can perform. It can perform calculations spontaneously. Billions of millions of calculations can be done simultaneously in few seconds. 2. Accuracy:  Computers are accurate. If the input is correct, then it is 100% accurate. Because what you give to the computer (input) is what
