Describe the Elements of computer?
Answer: Elements of computer: Computer is an electronic device for storing, processing data, typically in binary form, according to instructions given to it in a variable Elements of Computer: There are six element of computer system- 1. Hardware. 2. Software 3. Data 4. User 5. Procedures 6. Communication
1. Hardware: The physical components which we can see, touch and feel in the computer system are called hardware Example: Monitor, Keyboard, Mouse etc.
a) Input device: key board, Mouse, Scanner etc.
b) Processing unit: HDD/ Hard disk, processor, RAM etc.
c) Output device: Monitor, Printer, Speaker etc.
2. Software: Collection of program is called software. Software is a set of instructions can be used to solve real world problems. In computer which elements we can see but not touch is software.
Ex: Windows, MS-word, MS-Excel etc.
The set of instructions are commonly known as a program, without which computers cannot do any operations.
a) System software-windows 98/XP/2007/vista. Linux etc.
b) Application software-MS word, MS excel MS access etc.
3. Data : A primary collected knowledge which is not arranged is called data.
a) Numeric data: consists of digit (0, 1, 2... 9) and decimal point.
b) Alphabetic data: It is a used to represent 26 alphabets. It consists of capital letter from A to Z, small letter from (a to z) and back space.
c) Alpha Numeric data: Which data types are making up of letter (A-Z) and any digit (09) is called numeric data.
4. User: A person who design program and operate a computer is user
a) System analyst
b) Programmer
c) Operator
5. Procedure: Procedures are descriptions of how things are done, steps, for accomplishing a result.
6. Communication: When one computer system is set up to share data and information electronically with another computer system, communication.
Computer Systems
We are altogether mindful of what computers are and their gigantic significance in our day by day lives. It is an electronic gadget that stores information as well as cycles and controls information to do capacities. After accepting legitimate directions, a computer can play out an assortment of tasks.
What permits us to perform such errands on the computer is a computer system. A computer system is the aggregate of the multitude of segments (equipment and programming) that makes up a completely useful computer.
Components of a Computer System
There are six primary components that make up a computer system. They all connect with one another and play out the job that needs to be done. Allow us to investigate every one of them.
1] Hardware
These are for the most part the actual parts of a computer system. They are unmistakable, for example you can see and contact them. Equipment parts are the electronic or mechanical instruments, similar to console, screen, printer and so forth They help the clients interface with the product, and furthermore show the aftereffect of the errands being performed.Equipment can really be of four sorts, contingent upon which work they perform. The four kinds of equipment are,
Information Hardware: For clients to include information into the computer system. Models: Keyboard, mouse, Scanner
Yield Hardware: To interpret and show the consequence of the information preparing =. Model: Monitor Screen, Printer and so on
Preparing and Memory Hardware: Where information and data are handled and controlled to play out the job that needs to be done. It is additionally the workspace of the computer, where it incidentally stores information. Models: Central Processing Unit (CPU), Read Only Memory (RAM)
Auxiliary Storage Hardware: Where the computer system stores information forever. Model: Harddisk, Pendrive and so on
2] Software
Programming is only a bunch of projects (computer guidelines), which encourages the client to do a bunch of explicit undertakings. It assists the client with interfacing the computer system with the assistance of equipment. Programming, as you can envision, is the theoretical part of the computer system.Essentially, there are six primary sorts of programming, which are as per the following,
Working System: These particular projects permit the correspondence among programming and equipment. The working systems run the wide range of various computer programs, and even direct the startup cycle of the computer. Models: Windows XP, Macintosh and so on
Application Software: These are intended to play out a particular errand or a lot of assignments. They can be client planned (explicit to the client's requirements) or readymade application programming. Model: PowerPoint, Tally and so on
Utility Software: Like working systems, it is a system programming. It keeps up and ensure the computer system. For instance, Anti-infection programming is a utility programming.
Language Processors: Software that deciphers computer language and makes an interpretation of it into machine language. It additionally checks for blunders in language sentence structure and fixes the issues.
System Software: This kinds of programming control the equipment, the perusing of the information and other such inside capacities.
Availability Software: The extraordinary programming that encourages the association between the computer system and the worker. This permits the computer to share data and speak with one another.
3] People
Individuals cooperating with the computer system are likewise a component of it. We consider this component the Liveware. They are a definitive "clients" of the computer systems. There are three sorts of individuals that cooperate with the system, specificallyDevelopers: Professionals who compose the computer programs that permit clients to collaborate with the computer. They should have specialized information on computers and computer dialects.
System Analyst: They primarily plan information preparing systems, and take care of issues that emerge in information handling
End-Users: Also known as administrators, they are the individuals who connect with the computer system.
4] Procedures
These are a bunch of guidelines, written in code, to educate a computer on the best way to play out an assignment, run a product, do estimations and so forth There are three sorts of methodology in a computer They are,
Equipment Oriented Procedure: Instructs the equipment segments of the system, guarantees they work easily
Programming Oriented Procedure: Provides guidelines to dispatch and run programming programs
Inside Procedures: Directs the progression of data and arrangements the information
5] Data
Information is basically the crude raw numbers that we contribution to the computer. The information gets handled through the computer system and becomes data, which is prepared and coordinated information. Data would then be able to be utilized for dynamic purposes.The estimation of information is done as far as "bytes". One kilobyte (KB) is around 1000 bytes, 1 megabyte (MB) is 1 million bytes lastly, 1 gigabyte (GB) is roughly 1 billion bytes.
