TYPES OF COMPUTER:

 WHAT ARE THE TYPES OF COMPUTER? Different types of computer are as follows: Analog computer Digital computer Hybrid computer EXPLAIN: Analog computer: Analog computer represents physical quantities in the form of waves or in a continuous form.  Voltage , pressure, speed and tempreture are some pysicsl properties that can me measured in this way.  Its output is usually displayed on a meter or graphs.  Analog computer is difficult to use and operate. It has low memory and fewer functions.  It provides low accuracy but faster speed than digital computer.  It is usually built for special purposes.  Analog computer is mainly used in enegeering and scientific applications. Digital computer: Digital computer process data in numerical from using digital circuits.  It performs arithmetic and logic operations with discrete values 0 and 1. Everything is described as ON and OFF where 1 represents ON and 0 represents OFF. Digital computer can store and...

WHAT IS C++?

Any type of program written in small letter.  .cpp is an extension of C++ Execution of program to ctrl+ f9 For compile ALT+F9 SYNTAX OF C++:  # include<iostream.h>          #  this symbol known as preprocessor directive.          iostream is a header file. #include< conio.h>        voi...

WHAT IS ROUTER?

VISIT MY WEB TO GET INFO: https://techinfo4243.blogspot.com  NETWROK DEVICE: ROUTER: Router is a network device which works as a traffic controller. A main work of router is to choose a congestion free path through which the data packet will travel. Router recieve data packets from sender analyze it and forward those data packets to the reciever. NOTE: A router simply use for control of network traffic. There should must be a sender and reciever. When a sender send a data package to the reciever the work of router to check the address of data and then analyze where the data can be send to the reciever with consistency and without traffic. Router uses both LAN and WAN network. ADVANTAGES: It provides connection between two dis-similar type of network. Transmission rate is very high. It internally uses some algorithem to findout the congestion free path. It provides both wire and wireless facility. DISADVANTAGES: Router is more expensive than other network device. Router are complex ...

WHAT IS PROTOCOL? EXPLAIN:

NETWORK PROTOCOL: Protocol is set of rules which are used in digital communication to connect network devices and excahnge information between them. EXAMPLE: If an computer want to be connect to another computer there will be a set of rule known as PROTOCOL. Without set of rules there will be no any type of digital communication and sharing of data between two devices. To perform any task between two devices there  is a compulsery presence of set of rules that will be followed  by each of them. TYPES: TCP/IP For establishing connection and share info HTTP For searching purpose of any website SMTP For transmission of any mail POP Work as an like an mail box in the presence of sender and reciever FTP For transmission  of any file FOR MORE INFO  CLICK ON THE LINKS GIVEN BELOW: https://techinfo4243.blogspot.com/2021/04/what-is-ip-address.html https://techinfo4243.blogspot.com/2021/04/genenerations-of-computer.html https://techinfo4243.blogspot.com/2021/04/operating-...
