During the primitive age very little or no notes were taken into proper record especially those activities and transactions involving money. The records and notes were usually taken either in memory (human being) or some marks on the ground or trees.
As man developed from this primitive era to more complex economic society, there occurs notable growth and expansion in his way of life and activities he undertakes. During this time, the most disturbing problems that man faced was that there were no accounts and records. Being properly kept and stored. These therefore allow for inefficiency and breach of contract and trust.
The more developed man became the more the need for systematic record keeping and storage. The complexity of the society lead to chronological order of manual development in record keeping. Important records can be kept manually for future use but still in tedious way.
At a more technological era, more work was done in the accounting system. Accuracy, efficiency and durability became pressing problems that faced the manually kept and processed records in the accounting system, hence the development and introduction of electronic mechanical machine into the accounting system became very vital.
A systematic technological advancement however gradually gave birth to what is known today as the computer. A computer is an electronic device capable of accepting data as input, applying prescribed processes on such data and giving out an output which is called information, computer can also be said to be a machine that manipulates in accordance with given rules in a pre-determined manner. It is an electronic device that is used to process complex and variety of data within the shortest possible time: This is because it has very high speed of operation.
Data can get into the computer for processing via the input devices such as keyboards, diskette, CD Rom, punch cards, flash drive etc. the actual processing of data within the shortest possible time: this is because it has very high speed of operation.
Data can get into the computer for processing via the input devices such as keyboard, diskette, CD Rom, punch cards, flash drive etc. the actual processing of data takes place in the arithmetic and logical unit (ALU). The control unit (CU) is where all the activities of a computer system are being monitored or coordinated and planned. There also is the memory that is the unit in charge of storing or keeping all data or information in a computer system for a long and short period of time. This storage is made possible under the supervision of the ROM and RAM.
