What are the differentways of creating a network?There are a number of ways one can create a networksuch as through a,Router: Routers are devices thatconnect various computer networks through a wire or wirelessly. Ethernet Cable: Devices likecomputers get connected in a local area network through an ethernet cable.

Itis the most popular form of wired connection.Uninterrupted power supplies: Incase of power cuts or power outages people tend to lose data. To get protectedfrom such situation one requires a UPS. It keeps the computer running for aspecific period of time so that one can save its data before it gets lost.

 ?What are PLCs? PLC stands for programmable logic controller which takesdifferent inputs and does the decision-making process and generates an outputwhich goes to different machines and makes a system function. PLCs are typically used in production lines, machine functions or continuousprocess. Generally, PLCs function on feedback mechanism in which, the outputsare considered and accordingly the PLCs makes changes to generate a constantdesired output. PLC functions on a Ladder logic which is a programminglanguage. There are different programming languages available for PLC but theladder logic is the most popular.

Software: These days the software run by most of the top-notchphones is android Oreo which is the latest offering from google. However, incase of an iPhone it is IOS 11.? What are Mobile Devices?Mobile devices are also known as handheld computers.

Theidea behind mobile devices is to actually give convenience to the user. Thesedevices help their users to do all the things that they can do on alaptop/desktop but on a compact screen. There are plenty of mobile devices suchas tablets, smartphones etc. however, the most popular category of mobiledevices is Smart Phones. Smart phones also have a feature of cellular callingthat laptops/desktops don’t. Hardware: Hardware that goes intothe smartphones these days is so powerful that some laptop manufacturers areactually using the same processor for their laptops. Recently, HP’s Envy X2 and ASUS’sNovaGo laptops were launched.

These were launched with the snapdragon’sflagship processor which is known as Snapdragon 835. The same processor is usedby most of the flagship cell phones these days like Google Pixel 2 XL, GalaxyNote 8, ONEPLUS 5T etc. These arethe devices with the help of which we give an input and get an output.These perform simple functions but their presence is inevitable.

These devicesmake the user experience seamless. Some of the peripherals are mentioned asfollows:Keyboard: This accessory isconnected to the computer and is used to enter the data and give commands tothe computer through the keys on it. Computer Mouse: It is a device thatis used to point on the screen and held through a hand. As the user moves themouse, the cursor also moves on the monitor simultaneously.  Monitor: It is a device whichdisplays whatever is happening inside the computer. Printer: Printer is a device whichreceives the information from a computer and transfers it to a piece of paper.Printers need a cartridge having ink in it to give out a print out.

There is awide variety of printers in the market and they vary on basis of cost, speedand connectivity. For example: Some printers get connected wirelessly howeversome necessarily need wired connection to communicate with the computer. Scanners: Scanners are devices whichare used to simply scan the documents and get them on the computer. With thehelp of scanners, one can actually convert a hard copy in a soft copy.  ? What are peripherals?? Mother Board:Motherboard is one of the main components of the computeras it connects to all parts of the computer. It can also be called as abackbone of the computer. Mother board has the ports for CPU, RAM, Powersupply, sound and graphic card etc.

for easy operation of the user.?RAM:RAM stands for Random access memory. RAM acts just likean outer pocket of a handbag. Just like one can access a water bottle faster incase it is kept in the outer pocket instead of actually every time getting itout of the handbag, similarly, RAM helps the computer to keep the applicationsin memory instead of opening them each time a user wants to access them. Morethe RAM, more the applications can remain in the memory.? Cache:Cache is where the data is stored locally so that in future when is data isrequired, it can be fetched faster. There areseveral types of hardware caches such as CPU cache, GPU cache, DSPs etc.

?Whatis Quantum Computing?Quantum computing is done on high-end computers that areused in rigorous research activities.  ·       Selection of boot drives etc·       Configurating Hardware·       Starting and stopping certain systemcomponents·       Setting the system clock? Central processing Unit (CPU): CPU is an electronic component inside a computerthat basically receives commands from the software and transfers theinformation to the other components of the computer. It also denotes how fast acomputer can operate. The design, form and implementation of CPUs have changed over the period oftime, but their basic job remains the same.? PowerSupply Unit:            Power supply is a piece of hardware that facilitates in conversion of powerprovided from outside into power that can be used by many parts inside thecomputer.

It also controls voltageby regulating overheating. Power supply is one ofthe essential hardware components in a computer as without it, other internalhardware won’t function properly.? BIOS:                      BIOS stands for basic input/output system, this is the first thing one actuallysees when they turn on their computer. It’s a software that comes in the computer that initializes thehardware before booting an operating system from a hard-drive or any otherdrive. Following functions can be performed by the users using BIOS: Office Use: Desktops are used by the employees in a company wherein aspecific task has to be accomplished, however for the employees who keeptravelling for meeting clients or other work, laptop is the more beneficial.

  Letus understand the computer hardware components essentially required to use thecomputer in detail:               ? What are desktops, laptops and servers?A desktop computer is a computer which is meantto be kept on a desk and is not portable. A desktop comes in several componentsthat are connected to each other such CPU, RAM, motherboard etc. These devicesconnect directly with a power source instead of working on a battery.A laptop on the contrary is portable in nature and can operate on a battery fora few hours. It is relatively convenient to use than a desktop, howeverfor high power-consumptions tasks, desktops are preferred over laptops. A server is a computer, adevice or a program that is dedicated to managing network resources.

Serversare often referred to as dedicated because they carry out hardly any othertasks apart from their server tasks. There are a number of categories of servers,including print servers, file servers, network servers and database servers. Intheory, whenever computers share resources with client machines they areconsidered servers.Recently, Apple Launched its much-awaitedversion of Imac which is Imac Pro. This time the Imac has all-flasharchitecture, Intel Xeon processor with up to 18 cores.

Cost of the devicevaries from $5000 to $13000 depending upon the configuration selected.? Different Purposes of Desktops and laptops:Home Purpose: Both desktops and laptops are used for household purposes.However, it depends on the kind and quantum of work one has to do on thecomputer which determines the purchase. Gaming: For gaming, desktops have always ruled the market as heavy games needmore power and which can generally be given through high end desktops.Moreover, configuration can also be changed as per the user.In the case of Laptops it is generally not so comfortable to play games. Furthermore,they are heavy to carry around and there is always a hassle to keep itconnected to a power source as their battery drains quickly while playing suchgames.                                                                                  ? What is a computer?The word computer is derivedfrom a Latin word ‘computare’ which means ‘to calculate’.

It is basically anelectronic machine that can solve different problems, process, store andretrieve data and perform calculations faster than humans. There are severaltypes of computers such as desktops, laptops and server systems. Different types of computers are used by different people andorganizations depending upon their usage. For example, servers are generallyfound in businesses rather than houses as they have to manage many computers ata time.

                                                                                                                                                                                                                                                                  “Peoplewho are really serious about software, should make their own hardware”                   – Alan Kay?Why is hardware required?There may be plenty of reasonswhy hardware is important however the biggest reason amongst all is that,software can only be utilized through hardware. Without software, hardwaremight not be that appealing but it would somehow work. Another important use ofhardware is that, owning the hardware, facilitates in providing seamless userexperience. For instance, biggestreason for Apple products to be so popular, is their phenomenal userexperience.

Apple is able to provide such experience because it makes its ownhardware and software unlike the competitors which is also known as, VerticalIntegration Strategy.  Assignment1: HardwareSubject: Info. Systems & Knowledge management                      Prepared By: Sahil Behl (1049184)?Whatis hardware?Hardware is a generic term used for tools, equipment or their components usedfor a specific purpose.
