A computer system consists of hardware and software. :: Computer Science
A computer system consists of hardware and software program.A computer system consists of hardware and software. hardwareis theequipment, which makes up the computer system. Hardware consists of- Input devices such(prenominal) as keyboard, purloin, joystick- The Central Processing unit (CPU)- Output devices such as a printer, monitor, graph plotter- trade storage devices such as disc drive, hard drive- Media such as discs, tapes, paper etcThere is hardware that I used is shiner Keyboard Printer MonitorA tracker dinner gown walk====================A tracker freak hook is an input device and similar to a mouse scarce theball is set into a cup on the top of the unit. A finger or, on largertracker balls the palm of the hand, is used to roll the ball in anydirection. The ball controls the movement of the pointer on thescreen. Buttons on the tracker ball work in the same way as mousebutons to activate processes on the screen. My alternative of using amouse with a tracker ball wo uld be a mouse without a tracker ball. pull in========* A tracker ball does not require a large flat surface.Drawbacks==========* well-nigh people find them a bit fiddly* non accurate* Not quietALTERNATIVE Mouse without a tracker ball=========================================The pointer on the monitor screen mirrors the movement of the mouse bythe users hand. Under the mouse is a ball, which rolls as the mouseis moved. This movement of he ball causes devil shafts to rotate insidethe mouse one shaft records the movement in the north-south directionand the other shaft records the east-west movement. When the screenpointer is over a0n mental image or menu selection, the mouse button can beclicked, bivalent clicked or dragged to activate a process. some micehave a small(a) wheel as well as the buttons. The function of the wheeldepends on the software being used on the computer in a document, itcan allow the user to scroll up and down in a desktop publishingpackage, it might enable the user to speed in and out of the page. Overa period of time, the performance of the mouse can deteriorate as theball and shafts collect dust and dirt. Some modern mice use a lightbeam and detector to evidence movements instead off the mouse ball.Many mice now use infrared or wireless links to the computer, whichremoves the need to have a connecting cable.Benefit========* It is easy and convenient to use* It is inexpensive* Most modern software includes an option to use it.* It selects a position on the screen more than quickly than is possible
