What is Computer Fundamentals

What is Computer Fundamentals ::It can be describe as the learning or studying some basic functions of computer starting from their origin to modern day.

Study of basic computer types to their characteristics, advantages and disadvantages are included in the Learning of fundamentals of computers.

Before Shifting to advance computer knowledge it is highly recommended to be aware of this topic thoroughly as it would make you more confident and comfortable while acquiring more advanced computer skills.

Computer FundamentalsComputer Fundamentals

A Computer can be defined or described as a machine or device which can work with information such as to store. retrieve, manipulate, and process data. The term computer is derived from the word "computare".

The word is derived from a "latin" word which means to calculate. Therefore computer can be further defined as a programmable machine that is used for some numerical calculations. Some years back these devices | machines were used only for the purpose of calculations but presently they are widely and proudly used in all sections of human society.

The Modern Computers are incredibly advanced thanks to the new up-gradation and enhancement of technologies. They can store huge amounts of data in the internal as well as external storage units. Computer Hard disk is the external source of storing data.

These days computer speed has dramatically increased the work or task which used to take long hours to perform can be done in few seconds this is because of the rapid development in the IT [Information Technology] sector especially in computer hardware section

The Computer peripherals and devices manufactured these days are of highest quality with affordable price. The Technology has made these devices to perform more speedily than ever before also this is the important characteristics of computer system which made them very famous and a part of human lives.

It has also been observed than the life of modern peripherals and devices has been extended due to the excellent quality of raw material used while preparations of these devices.

For example the warranty a hard disk drive is up to 2 to 5 yrs.

The Speed of computer mainly and primarily depends upon some factors such as What type of motherboard you are using, Processor Speed and RAM [Random Access Memory].

Motherboard :: Computer Motherboard is designed on a piece of PCB Which is called as Printed Circuit Board where all other components are attached to it such as hard disk ,processor, ram, etc.

Processor :: Processor is again called as CPU which stands for central Processing Unit.It is also called as Heart | Brain of Computer System.

RAM :: RAM stands for Random Access Memory which is temporary storage medium and it's volatile memory. They tend to lose data when power is off.

However, the speed of the computer depends upon ram as well. You can install more capacity of ram to increase your computer speed but firstly you have to check the compatibility factors of motherboards and other components or the device.

Hard Disk :: This is a permanent storage unit of a computer which can store data in high volume and also you can retrieve data whenever and wherever you need. These HDD available in market in huge data storing capacity.

Basic Fundamental Functions of Computer

There are mainly four common functions of computer system

  • Input
  • Output
  • Processing
  • Storage

Input :: The Computer receives its data from input devices in the form of raw data and later this data is processed in human readable form with the help of other computer devices.
The primary input devices of computer system are

  • Keyboard
  • Mouse
  • Scanner
  • Trackball
  • Lightpen
  • Joystick

Output :: The output devices of computer receives data from system and further process the data in human readable form .

Some common output devices are ::

  • Printers
  • Monitors
  • Speakers
  • Headphones
  • Projectors

Processing :: This is the core function of modern day Personal Computer. When the data is received from the memory it transfer the data or information for further processing.

Storage :: There are mainly two storage unit of personal computer [PC]

  • Primary Storage
  • Secondary Storage

Primary Storage :: Random Access Memory [RAM] is the primary storage unit of computers.

Secondary Storage :: Hard Disk Drives and Pen drives are called as secondary Storage unit.

Different Types of Computer

The overall development of computer has reached to new heights due to vast improvement in modern technology. The fundamentals of computer has changed rapidly.They are categorized in four different types according to their speed, size, capabilities and cost.

  • Super Computer
  • Mainframe
  • Mini
  • Micro

Super :: They are the fastest and most expensive computers compared to others. They require huge space for their installation.

Mainframe :: They are not as fast as super computer and require huge space for installation also they are very expensive.

Mini :: They are smaller, cheaper and slower compared to super and mainframe computer.

Micro :: They are called as Personal computer [PC]

Advantages of Computers

Nowadays computers are playing a vital role in the development of the human society they are making workload as easy efficient and fast you would not have imagined before.

If you ask me what is the basic fundamental advantage of the computer. I will say its role in studying. The Students can learn literally anything on the computer with internet connectivity from science to philosophy and acquire necessary skills from online platforms to build their professional career.

Use of modern day computer in studying has changed the style and learning methods of students people don't want to waste their time in searching for good coaching classes in their town they prefer online study where they can get quality education with online certificates and even degrees.

Students can learn online with their own convenience. The study material is in the form of digital medium such as PDF, DOC, images, info-graphics and video format for better understanding.
Below I have mentioned some of the basic advantages of Computer

  • Online Education
  • Business
  • Speed
  • Accuracy
  • Online Education
  • Military
  • Research

Disadvantages of Computer System

As there are numerous advantage of using modern day personal computer there are disadvantages too.

  • Spread of Pornography
  • Hate & Violence Related Articles
  • Cyber Crimes
  • Negative Effect on Health

Computer Software and Hardware

The computer software can be described as a collection of small programs that are programmed in such a way which are capable of performing specific and special task whenever desired.

These types of software are developed by computer programmers or software developers which takes care of users needs and intent. There are mainly two types of software::

  • System Software
  • Application Software

System Software :: These are those software which directly interact with the computer system. The primary examples are Operating systems [OS] and device drivers.

Application Software:: These are also called as customized software which are developed for personal use or developed for customers to perform some specific task.
Example:: Tally , Ms-office , ERP Software's
