TOPIC: DIGITALIZATION OF DATA

The process of digitalization has revolutionized the way we store and access data. It has completely changed the way businesses operate and how we communicate with each other. With the help of digitalization, businesses have been able to store large amounts of data more securely and efficiently. They have also been able to share this data with employees, partners, and customers more easily and quickly.

 

 

 

Digitalization has also made it possible for us to access data from anywhere in the world. We can now retrieve information and share it with others instantaneously. This has made communication and collaboration much easier and more effective.

 

 

 

The process of digitalization has also made it easier for businesses to track and analyze data. They can now identify trends and patterns more easily, which helps them make better decisions. Additionally, businesses can now target their marketing and advertising efforts more effectively.

 

 

 

Digitalization has truly revolutionized the way we store, access, and share data. It has made communication and collaboration much easier and more effective.

 

 

Digitalization is the process of converting information into digital format. This information may represent an object, image, sound, document or a signal (usually an analog signal) organized into discrete set of its points or samples. This is the binary data that computers and many devices with computing capacity (such as digital camera and digital hearing aids) can process.

 

Digitalization can also be defined as the integration of digital technologies into everyday life. Digital system uses a binary numeric system in which electronic pulses are represented by either 0 for a Low pulse or 1 for a High pulse. Digital can more easily represent symbols such as alphanumeric characters that represent real world data than the analog system.

 

BENEFITS OF DIGITALIZATION

1. Long term preservation of documents
2. Orderly archiving of documents
3. Easy and customized access to information
4. Easy information dissemination through images and text, CD-ROM, Internet, Intranet and extranets.

TYPES OF DIGITAL COMPUTER

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

 

TECHNOLOGY OF DIFFERENT INFORMATION AGE

The ages are:

1. Stone age
2. Iron age
3. Middle age
4. Industrial age
5. Electronic age

 

Information age	Tools used	Purpose	Time period	Examples of tools in that age
Stone age	Stone	Sewing, cutting, counting, defence, transaction, storage, pottery exhibitions.	Below 12th century	Basalt, sandstone flint etc.
Iron age	Iron	Defence, Agric	12thcentury	Hoes and cutlass
Middle age	Writing materials	Knowledge transfer, education	12th and 13th century	Pen feather etc
Industrial age	Coals	Power development, faster movement	Late 18th and early 19th century	Cars, Ships etc
Electronic age	Computer	Storage, accuracy, soeed. Timeliness	Late 19th century and above	Circuit, Processor.

 

EVALUATION

1. State the different information ages.
2. State the tools used in each age.

 

EARLY COUNTING DEVICES

1. Fingers and Toes
2. Stone
3. Sticks
4. Pebbles
5. Cowries

In the early days of man’s existence on earth, counting and simple arithmetic were performed using different parts of the body and some other counting aids. The following are devices used by people of ancient times.

 

FINGERS AND TOES

In ancient times, calculations were done by the use of fingers and toes. Fingers were used for simple addition and toes were used together with fingers in order to count up to twenty. The following problems were faced using fingers and toes to count:

1. They could not be used conveniently to count numbers more than twenty.
2. The result obtained from counting with fingers could not be easily remembered.

STONES AND PEBBLES

Stones were introduced for counting because of the limitations of counting with fingers       and toes. Counting with stones involves building a pile of stones where each represents a quantity. The following were problems faced using stones as counting devices:

1. Large numbers of stones were too heavy to carry from one place to other.
2. It was cumbersome to count if the counting process involved large numbers.

 

GRAINS

The use of grains was introduced because of the heaviness of stones. Grains can be kernel, beans, rice, corn etc. Grains were used the same way as stones.

 

STICKS

These are small pieces of wood that are used for counting in place of stones and grains. Children in nursery and primary schools use match sticks for counting.

 

MARKS ON THE WALL

This involves the use of sharp objects in drawing line on the wall for the purpose of counting.

Continuous marks on walls will make a wall dirty.

 

DISADVANTAGES OF EARLY COUNTING DEVICES

1. They are difficult to carry about.
2. Counting and calculation takes a lot of time.
3. They are prone to mistakes.
4. They cannot be used to count or calculate large numbers.
5. Their results cannot be easily remembered.
6. They have no storage facilities.

 

GENERAL EVALUATION

1. Mention types of computer according to sizes.
2. Which of the size is used for weather forecast?
3. Another name for mainframe computer is ……
4. List any two examples of mini computers.
5. Mention the four categories of computers.
