First of all I really thanks to siz-official and cryptokraze who provide a great platform to show our talent and skills to other, so that many more peoples learn a lot. Now some days ago I applied for a course about IT, so my course is approved now here I posted my first lecture below. I hope you learn a lot and enjoy it.

Basic Consept Of IT

So Let's Start:

Now first of all we discuss about software and hardware.

Software and Hardware:

A lot of rules given to the PC to handle an issue is called programming. Writing computer programs is in like manner called program. Different writing computer programs' are used to deal with different issues. A PC fills in according to the headings sent in programming. The real bits of the PC are viewed as hardware the customer can see and contact the gear. Control center and mouse are occurrences of hardware.

Relationship of software and hardware:

Writing computer programs is a lot of rules that trains the PC hardware. The hardware can't play out any endeavor without programming. The item can't be executed without hardware. A PC becomes supportive exactly when gear and writing computer programs are combined.

What is Data?

An assortment of crude realities and figure is called information. The word implies that the realities are natural. Information is given to the PC for preparing. Data is collected from different sources.

What is Information?

The processed data is called information. It is more meaningful than data. It is used for making important decisions. Information can be handled in various ways to deliver the necessary data.

What is Data Processing?

The most common way of changing over information into data is called information preparing. Information is the information and data is the yield of an information handling framework. It is otherwise called processing. Information handling comprises of various advances that are acted in a grouping.

Basic steps:

• Input
• Processing
• Output

What is Computer?

A PC is a machine that can be customized to acknowledge information measure information into valuable data and store it for some time in the future. A computer consists of hardware and software. The machine is known as hardware. The programs are called software.

What are input output and processing device?

1 . Input Devices:

Anything given to the computer such as data or instructions is called input. Information gadgets are utilized to enter information and directions into the PC. These gadgets send this information to the preparing unit. Most usually utilized info gadgets are console and mouse.

2 . Output Devices:

The information prepared into helpful data is called output. Output gadgets are utilized to show the consequence of handling. The most widely recognized yield gadgets are screen and printer.

3 . Processing Device:

The processor is used to process data. It is also called central Processing Unit. It is the brain of the computer. It consists of electronic circuit CPU interprets and executes program instructions. Many memories are used to hold data and instructions being executed by the CPU. It keeps data and instructions temporarily.

What are storage and pointing devices?

1 . Storage Devices:

Storage usually refers to the secondary storage. The storage devices are used to store data programs and information permanently. The most common storage devices are hard disc drive USB flash drive and optical discs such as CDs and DVDs etc.

2 . Pointing Devices:

An information contraption used to control a pointer on the screen is called pointing gadget. A pointer is a little picture that appears on the screen in graphical UI. A pointing device can be used to select text graphics and other objects such as button icon and menus commands.

Some important pointing devices are as follows:

• Mouse
• Track ball
• Pointing Stick
• Touchpad
• Touch screen
• Light pen
• Joystick
• Pen-based system

What are source data-entry devices?

Source information section gadgets are utilized for direct information passage to the PC framework. These gadgets give a speedy and proficient approach to enter information.

Types:

• Scanning Devices:
• Barcode reader
• Mark and character recognition devices
• Magnetic ink character recognition reader
• Optical mark recognition
• Optical character recognition
• Magnetic strip
• Smart cards
• Facsimile fax machine
• Imaging system

Note on Barcode Reader:

Barcode reader uses a laser beam to read barcodes and translate them into digital signals. The digital signals are then further processed by the computer. Barcode are the vertical lines of different words and spaces. The barcode represents data that identifies the manufacturer and the product.

What are basic units of data storage?

Bit:

The binary digit 0 or 1 is called bit. Computer works with binary digits. 1 byte takes one storage location in memory.

Byte:

A collection of 8 bits is called byte. It is used to store single character

Kilobyte:

A kilobyte consists of 1024 bytes. It is denoted by KB

Megabyte:

A megabyte consists of 1024 kilobyte. It is denoted by MB.

Gigabyte:

A gigabyte consists of 1024 megabytes. It is denoted by GB.

Terabyte:

A terabyte consists of 1024 gigabyte. It is denoted by TB.

Word:

A computer word is the number of bits in common unit of data defined by the computer system. It is normally the size of register. The length of a word is different in different computers. The large word size indicates more powerful computers.

User Training:

The readiness of customers is essential to run the new system successfully. The customers ought to be arranged suitably to use the new system enough. The customers may in like manner require manuals and reference information. PC Based planning (CBT) is renowned for setting up the customers.
