Introduction of Digital computer

INTRODUCTION
Digital computer concept:-
1.Digital computers are designed to store, process and communicate information in digital form.

2.Digital computer is any of a class of digital devices capable of solving problems by processing information in discrete form.

3.It is used for processing data represented by discrete, localized physica signals, as the presence or electic current.

4.The main three components of digital computer:-
>input:- The user gives a set of input data through input devices.
>Processing :-The input data is processed with the help of CPU by well defined and finite sequence of step.
>Output :- Some data available from the processing step are output to the user.

TYPE OF DIGITAL COMPUTER :-

1.Microcomputer/Desktop computer
2.Minicomputer
3.Mainframe computer
4.Supercomputers

Microcomputer :-
1.Microcomputer is also called a personal computer or desktop computer.

2.It includes a microprocessor, memory, and input/output devices.

3.It includes workstations, desktops, servers, laptop and notebook.

4.Examples are the IBM pc, Apple Macintosh, dell, hp.


MINICOMPUTER :-

1.Minicomputers emerged in the mid-1960s and were first developed by IBM corporation.

2.This computer fills the space between the mainframe and microcomputer.

3.This may also be called a mid-range computer.

4.Example are DEC'S, VAX, RANGE.


MAINFRAME COMPUTER :-

1. Mainframe first appeared in the early 1940s.

2.The market is dominated by IBM.

3. Ability to run or host multiple operating systems.



SUPERCOMPUTERS :-

1. A Supercomputers is a mainframe computer that has been optimized for speed and processing power.

2.Supercomputers are primarily are designed to be used in enterprises and organization that require massive computing power.

3.Supercomputers processing speeds are measured in floating point operations per second, or FLOPS.

INTRODUCTION OF DBMS

-
What is Database :- The database is a collection of inter-related data which is used to retrieve, insert and delete the data efficiently. It is also used to organize the data in the form of a table, schema, views, and reports, etc. For example: The college Database organizes the data about the admin, staff, students and faculty etc. Using the database, you can easily retrieve, insert, and delete the information. DBMS (Database Management System):- Database management system is a software which is used to manage the database. For example: MySQL, Oracle, etc are a very popular commercial database which is used in different applications.DBMS provides an interface to perform various operations like database creation, storing data in it, updating data, creating a table in the database and a lot more.It provides protection and security to the database. In the case of multiple users, it also maintains data consistency. DBMS allows users the following tasks:- Data Definition: I

Introduction to cache memory

Cache Memory in Computer Organization Cache Memory  is a special very high-speed memory. It is used to speed up and synchronizing with high-speed CPU. Cache memory is costlier than main memory or disk memory but economical than CPU registers. Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU. It holds frequently requested data and instructions so that they are immediately available to the CPU when needed. Cache memory is used to reduce the average time to access data from the Main memory. The cache is a smaller and faster memory which stores copies of the data from frequently used main memory locations. There are various different independent caches in a CPU, which stored instruction and data. Levels of memory: Level 1 or Register – It is a type of memory in which data is stored and accepted that are immediately stored in CPU. Most commonly used register is accumulator, Program counter, address register etc. Level 2 or Cac
