Classification of computers

Classification of Computer :
•Analog Computer
•Hybrid Computer
•Digital Computer
♥ Analog computer :
•An analog computer represents the data as physical quantities and operates on the data by manipulating the quantities.
•It is designed to process data in which the variable quantities vary continuously.
♥ Hybrid computer :
•A hybrid is a combination of digital and analog computers.
•It combines the best features of both types of computers, i.e. It has the speed of 
an analog computer and the memory and accuracy of digital computer.
•It accepts analog signals, converts them into digital and processes them in digital form.
•A hybrid computer may use or produce analog data or digital data.
•It accepts a continuously varying input, which is then converted into a set of discrete values for digital processing.
♥ Digital computer :
•A digital computer is designed to process the data in numerical form, its circuits perform mathematical operations of addition, subtraction, multiplication and division.
•The numbers operated on by a digital computer are expressed in the binary 
system.

OSI Layers and their work

OSI (Open system interconnection) Layers :- (1) Application Layer :-  Manipulation of data, mail service etc. are provided, uses web browser. (2) Presentation Layer :-  Perform by OS that converts HLL to MLL, maintain encryption & decryption. (3) Session Layer :- Manages conversation between two different applications, Manages session b/w source and destination. (4) Transport Layer :-  Decides data transmission should be on parallel or single path, It breaks message into packets & maintain it should reach destination with reliability. (5) Network Layer :-   Acts as network controller, Decides which route data should take. (6) Data Link Layer :- Error controlling, Error detection bits are used. (7) Physical Layer :- Activates, maintain  & deactivate Physical connection, It converts digital bits into electrical signals. BONUS FACTS  :- Hub :-  Works on Physical Layer. Switch :- Works on Data Link Layer. Bridge :- Works on Data Link Layer. ...
