Basics of Software and Hardware

Hardware and software are essential parts of a computer system. Hardware components are the physical parts of a computer, like the central processing unit(CPU),mouse,storage,and many more. Software components are the set of instructions that we store and run on our hardware. Together, they form a computer.

Computer Memory

Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts called cells. Each location or cell has a unique address, which varies from zero to memory size minus one.

Output Devices and Input/output Ports

An output device is any piece of computer hardware equipment which converts information into a human-readable form. A port serves as an interface between the computer and other computers of pheripheral devices.

Programming Language

A programming language is a formal language comprising a set of strings that produce various kinds of machine code output. Programming languages are one kind of computer language, and are used in computer programming to implement algorithms. Most programming languages consist of instructions for computers.

Representation of Data/Information || Concept of Data Processing || Applications of IECT

Data Representation refers to the form in which data is stored, processed, and transmitted. Data processing is, generally, "the collection and manipulation of items of data to produce meaningful information." Multimedia refers to combination of text, audio, video, graphics, animation, etc. It is one of applications of IECT.

Basics of Operating System

An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.

Some popular Operating System

The three most common operating systems for personal computers are Microsoft Windows, macOS, and Linux. Modern operating systems use a graphical user interface, or GUI.

User Interface

The user interface (UI) is the point at which human users interact with a computer, website or application. The goal of effective UI is to make the user's experience easy and intuitive, requiring minimum effort on the user's part to receive maximum desired outcome.

row - cells aligned horizontally. 

column - cells aligned vertically. 

range - the specification for a series of cells. 

function - an operation applied to a range of cells, always beginning with an "=" sign.

Manipulation of Cells

The collection of means for precise control of the static or dynamic position of individual biological cells with the purpose of observing, probing, and/or altering the cellular responses.

Functions and Charts

A chart is a tool you can use in Excel to communicate data graphically. Charts allow your audience to see the meaning behind the numbers, and they make showing comparisons and trends much easier.

Basics of Computer Network || Internet
