In this article, you will know what is Hard Disk and what are these types? Hard disks are also often called Disk drive or "Hard Disk Drive (HDD)". Just as a library is required to handle books in the library, the same computer also needs a similar place in which it can store digital data .  Computers use two types of storage devices to store and process digital content (Document, Image, Videos, Software, Operating system, Program). In which Hard Disk is a secondary memory device. It keeps the data stored permanently. Whereas the primary memory device (RAM) serves to process the program of the computer . It is also called temporary memory. Hard Disk is seen as an important component of a computer because no computer will work without it. In this post we will tell you what is a hard disk in a computer ? In which you will get to know a lot about Hard Disk. So let's first know, what is called a hard disk and then we will talk about other aspects of it. What is hard disk ...

  We need to give instruction to the computer , to begin the process of solving problems or to accomplish certain tasks. A set of predefined instructions in logical manner makes up a program. One of the most important aspect of computer field is to make ' Programs '. A program is written in a computer language, like BASIC, ' C ', ' C++ ', Python , etc. A computer language consists of codes which are combined in accordance with a predefined syntax. that conveys the instruction to the components (ALU) of CPU. In this section, I am discuss about how to solve problems by developing simple programs with the help of the computer language; ' Python ' What is Python ?  Python is an interpreted, high-level, general-purpose programming language. This language  Created by Guido van Rossum and first released in 1991 . Python is a very simple and powerful language. It helps to create programs in computer. Python has involved into a useful language as it is simple ...

  5G is the fifth generation of mobile networks . Think of 5G in such a way that 4G is 100 times the speed of the network.  Like 4G, 5G is based on the same mobile programming principle. Fifth generation voice technology is capable of delivering ultra low latency (signal speed between your phone and tower) and multi-Gbps data speeds. It is a software-based network, developed to increase the speed and functionality of wireless networks . This technique also increases data quantity, which can be transmitted to wireless networks . 5G technology forms the basis of five technologies 1. millimeter wave 2. Small Sales 3. Maximum MIMO 4. Beamforming 5. Full duplex 5 bases of 5G technology The 5G technology is capable of operating in the "sub-6 band", with frequencies typically between 3Ghz-6Ghz. Most current devices like mobiles,  tablets and laptops also operate in the same frequency, which has a very high reach. Millimeter-wave 5G The millimeter-wave 5G acquires a lot of data...

Network in computer system Based upon geographical area, networks can be divided into three broad categories: LAN MAN WAN LAN (Local Area Network) : LAN is a type of network in which computers (nodes) are connected in a local unit or small geographical area, such as offices, department of a manufacturing unit, etc. The common connecting media used in LAN are cables, wi-fi etc. LANs are restricted in size and are convenient to handle. Characteristics of LAN: In LAN, data communication takes place at a rate of 100-1000 mbps. It is owned by an individual or an organization. It provides the user with an access to share several common hardware resources viz. computers, terminals, printers, server etc. There is no specific tariff for its usages. MAN (Metropolitan Area Network) : Man is a type of network in which the computers are connected over large geographical area such as a city. It may be a single network or may be a network that connects several LANs. MAN may be operated by a single or...

Application of Computers /Communication/  In the past, people used to communicate through letters, telephones etc. The advent of computers has made it possible to share or exchange information in real time i.e.  instant exchange of information, be it textual, Graphical or visual form any corner of the world in different ways:  Email : It enables to send the soft copy of letters, images or videos instantly to any user of a computer on the internet. Online Chatting : It helps to establish real time communication by exchanging the typed  instantly (Instant Messenger) on the computer. Such a facility has enabled communication groups between two or more people at the same time from far off locations thus forming newsgroups. Video Conferencing : It enables a live streaming of visual between two or more people through computers and the Internet . FTP : It enables to transfer files between computers which are connected in a network. Telnet: It is a facility which enables to ...
