Can refer to the use of automated methods to process commercial data. Typically, this uses relatively simple, repetitive activities to process large volumes of similar information. For example: stock updates applied to an inventory, banking transactions applied to account and customer master files, booking and ticketing transactions to an airline's reservation system, billing for utility services.

Can refer to the use of automated methods to process commercial data. Typically, this uses relatively simple, repetitive activities to process large volumes of similar information. For example: stock updates applied to an inventory, banking transactions applied to account and customer master files, booking and ticketing transactions to an airline's reservation system, billing for utility services.

Example:Windows 7 (OS), MS Word, MS Excel

Is a collection of computer programs and related data that provides the instructions for telling a computer what to do it. Software refers to one or more computer programs and data held in the storage of the computer.

Set of instructions that your hardware executes to carry out a specific task for you.

Is any language from a class of computer language, specification language for formal description and design of electronics circuits, and most commonly, digital logic. It can describe the circuit’s operation, it’s design and organization, and test to verify its operation by simulation.

Input Device – Mouse, Keyboard, scannerOutput Device - Monitor, Fax LCD Storage Device – Hold information is a recording medium like Tape, Disk, Flash drive

Refers to anything that has to do with the role of people in the development or use of computer software and hardware systems.

Example:Software Developer, System Analyst

Speed - it operates the speed of electric flow which is measured in billions and trillionth of a second. It is faster than any other machine designed to do similar works.

Accuracy - High speed processing by computer is accompanied by high accuracy results the electronic circuitry of computer is such that, when the machine are programmed correctly and when incoming data is error free, the accuracy of the output is relatively assured.

Automatic operation - An electronic computer can carry out sequence of many data processing operations without human interaction, the various operations are executed by way of a stored computer program

Decision making capability - A computer can perform certain decision instruction automatically

Compact storage - Electronic data processing system have the ability to store large amounts of data in compact and easily retrievable form

Discipline Imposes - to solve problem-with computer you must, first understand the problem, second, program the computer to give you right answers. Understand a problem is one thing but understanding it to the depth of detail and insight required to program the computer is a completely different matter

 Power failure, computer viruses and hackers are the inherent problems of using computerized systems;·Once data been input into the system, automatically the output are obtained hence the data being input needs to be validated for accuracy and completeness, we should not forget concept of GIGO (Garbage In(Input) Garbage out ( Output) and· Accounting system not properly set up to meet the requirement of the business due to badly programmed or inappropriate software or hardware or personnel problems can caused more havoc and· Danger of computer fraud if proper level of control and security whether internal and external are not properly been instituted.

A stored-program computer is one which stores program instructions in electronic memory. Often the definition is extended with the requirement that the treatment of programs and data in memory be interchangeable or uniform
