Answer 1

Answer:

1.DATA:An unorganized and raw facts collected about an particular object    called as data.

Example:Data collected by

Information:The organized and processed data is called as an information.Without data there is no information.

Example:

2.The functional units of a Computer System are

1. input unit: In input unit data is entered that needs to be excecuted through input devices like Keyboad
2. central processing unit: CPU consists of

• Memory Unit : stores the input data
• Arithmetic and Logic unit: performs Arithmetic and Logical Operations on input data
• Control Unit: controls the flow of data.

   3.Output Unit:Output unit displays the processed data which can be easily undestand by the programmers on the display devices like laptop       screens.

3.Storage Unit :The unit which stores entered input data and its internally generated values during Arithmetic and Logical operations perfomance called as Storage Unit.

The storage Unit is mainly divided into 2 types mainly

• Primary Storage Unit: It's also called as temporary storage unit.The information stored in this unit will be lost once the system is turned off.

• Examples:RAM-Read Only Memory
• ROM-Read Only Memory.

• Secondary Storage Unit: It's also called as Permenant Storage Unit.

        Examples:Hard disks,Floppy disks.

4.Linux:

• It's open source software available free to everyone.
• Linus uses  a tree likr a hierarchial file system(You will learn more about this in Data Structure Concepts)

Windows:

• It's not an open source software.
• It's uses different storage devices like C drive to store data.

5.Difference between LAN,MAN,and WAN:

• Land Area Network(LAN):Covers a small area such as house wifi networks.
• Metropolition Area Network(MAN):Covers area larger than LAN but smaller than WAN such as local radios network,metropolitic cities like Hyderabad,Vizag etc.
• Wide Area Networks(WAN):Extends over a large geographical area's like Jiotelecommuication services.
