What are basic computer skills?

Basic computer skills refer to your ability to perform fundamental tasks on a computer. This can include understanding certain software, applications, programs, tools and more. Computer skills fall into two categories: software and hardware. Hardware refers to the computer's operation, whereas software involves the use of various programs and applications.

The type of computer skills you'll be expected to have will depend on your industry. Typically, employers specify what types of computer skills they want their employees to have in their job postings.

How to improve basic computer skills

Here are a few ways to improve your basic computer skills:

Some of the Basic Examples of the course of Basic Computer which includes in this syllabus as follows:-

Input-Process-Output Model

Computer input is called data and the output obtained after processing it, based on user’s instructions is called information. Raw facts and figures which can be processed using arithmetic and logical operations to obtain information are called data.

Workflow

The processes that can be applied to data are of two types −

1. Arithmetic operations − Examples include calculations like addition, subtraction, differentials, square root, etc.

2. Logical operations − Examples include comparison operations like greater than, less than, equal to, opposite, etc.

The corresponding figure for an actual computer looks something like this −

The basic parts of a computer are as follows −

1. Input Unit − Devices like keyboard and mouse that are used to input data and instructions to the computer are called input unit.

2. Output Unit − Devices like printer and visual display unit that are used to provide information to the user in desired format are called output unit.

3. Control Unit − As the name suggests, this unit controls all the functions of the computer. All devices or parts of computer interact through the control unit.

4. Arithmetic Logic Unit − This is the brain of the computer where all arithmetic operations and logical operations take place.

5. Memory − All input data, instructions and data interim to the processes are stored in the memory. Memory is of two types – primary memory and secondary memory. Primary memory resides within the CPU whereas secondary memory is external to it.
