Internet of things (IoT): The network and communication of digital, mechanical and electronic devices is known as IOT or internet of things. In IOT, device-to-device communication is done. While on the internet there is another type of communication going on like people-to-device and device-to-people. IOT is a new technology first revealed in 1999 by Kevin Ashton. IoT Example IOT is used for ease of our lives and to [...]
What are software and hardware? Computer software and hardware work together to make a computer. In all computer devices i.e. smartphones, personal computers and other types of computers, the hardware is the main part of the computer/device. First I will discuss both software and hardware. What is software? Software is a set of executable code that is run by the CPU (central processing unit). Computer software also includes [...]
Basics about the virtual private network (VPN) The virtual private network gives you the security to connect with the internet. ISP (internet service provider) gives you access to the internet. ISP receives/sends your requests to the internet. Suppose you type google.com in the chrome. Now that request is first sent to the ISP and then ISP request data from google.com server and send to your chrome browser. Note [...]
Definition of internet Internet is a global network in which all computers and devices are connected with each other through ISP, routers and servers. If any computer/device is connected to the internet then it can communicate with any other computer/device on the internet. The communication may be in the form of exchanging text, picture, video, voice and game/software. Internet History of internet In 1960, the United States Department [...]
What is the storage area network (SAN) A storage area network is a network in which server machines are connected to storage devices through switches. Fiber optics is used as a cable for connection between switches, servers and storage devices. The reason for using fiber optics is that it has high transfer speed i.e. 5 GBPS. The benefit of using fiber optics is that servers feel that storage [...]
Definition of mainframe computer A mainframe computer is a large computer with hundreds of processors. It can process a larger amount of smaller tasks quickly. A mainframe computer is smaller than a supercomputer. The supercomputer is the larger and fastest computer ever made. Mainframe computers have the size of a refrigerator. Before 2000, these computers were big in size covering the whole room. But now these computers have [...]
Definition of microcomputer: A microcomputer is a computer with CPU (central processing unit), keyboard, mouse and screen. This type of computer is also known as PC (personal computer) or desktop PC. This computer is smaller than mainframe and supercomputer. PC is used at the home or in commercial area. The microprocessor is main part of PC and do all processing. Pros and cons of microcomputer Advantages of microcomputer: [...]
Definition of campus area network (CAN) CAN is a type of computer network in which different computers and devices are interconnected with each other. CAN is made by combining small LAN’s (Local Area Networks). CAN is smaller than WAN (Wide Area Network). CAN is also known as corporate area network when it is installed in a large company. CAN is also known as a controller area network. Campus [...]
The microcontroller is embedded in the devices to perform different actions. The microcontroller is a chip in which RAM, ROM, PROM is used. The examples of devices in which microcontroller is used are scanners, photocopiers, printers, fax machine, ATM, smart meters, and security meters. Microcontroller vs microprocessor The microprocessor also knew as CPU is used in computers and smartphones. RAM, ROM is not built into microprocessor [...]
Computer users can interact with one and another through some type of network. There are many types of network and we name the network depending upon how long distance the network covers. If the network is within the room or couple of rooms then we name it local area network (LAN) and if the network is all over the world then we name it wide area network (WAN). [...]
