Microprocessor and Primary Storage TG1.5 Input/Output Devices TG1.1 Components of a Computer System Computer hardware is composed of the following components: central processing unit (CPU), primary storage, secondary storage, input devices, output devices, and communication devices. Communication devices are covered in detail in Tech Guide 4. The input devices accept data and instructions and convert them to a form that the computer can understand. The output devices present data in a form people can

amount of current to continuously flow through it once it is accidentally triggered or turned on. Depending on the circuits involved, the amount of current flow produced by this mechanism can be large enough to result in permanent destruction of the device due to electrical overstress (EOS) 2)Why is NAND gate preferred over NOR gate for fabrication? NAND is a better gate for design than NOR because at the transistor level the mobility of electrons is normally three times that of holes compared to NOR

IR sensor. The IR transmitter is used to transmit the infrared rays in our eye. The IR receiver is used to receive the reflected infrared rays of eye. If the eye is closed means the output of IR receiver is high otherwise the IR receiver output is low. This to know the eye is closing or opening position. This output is give to logic circuit to indicate the alarm. This project involves controlling accident due to unconscious through Eye blink. Here one eye blink sensor is fixed in vehicle where

1 Design of Logic Circuits 1.1 Basic Revision of Logic Gates In the following chapter, we assume a two input logic gate with inputs A and B. 1.1.1 Simple Gates i. AND Gate The symbol and truth table for an AND gate is shown below: A B A.B 0 0 1 1 0 1 0 1 0 0 0 1 Summary: If inputs A AND B are high then the output is high Abbreviations: often a ‘.’ (dot) is used to signify the AND operator when writing Boolean equations. ii.

Introduction:- Computer is an electronic device which can take input from the user and process this input data and if need, store data or information on storage devices and give output on output devices. It follow the instructions us it is which we input. It takes input through Keyboard, mouse, etc and then it processes the input data and give output on display screen and store data if need. Desktop Computer:- Mostly called personal computer (PC), design to fit completely on a typical desk

the functions of computer’s central processing unit (CPU) on a single integrated circuit (IC), or at most a few integrated circuits. The microprocessor is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output. 2. A digital signal processor (DSP) is a specialized microprocessor (or a SIP block), with its architecture optimized for the operational needs of digital signal processing. 3. A graphics

On-Off Control System controlling the operation of heater using microprocessor. It is a closed-loop control system. An on-off controller is the simplest form of temperature control device. An on/off controller will switch the output only when the temperature crosses the set point. For heating control, the output is on when the temperature is below the set point, and off above the set point.The paper deals with control system including strategies, types and requirements of control system. Block

multi-tasking, two features essential for multi-user systems. The Hard disk of a multi-user system is bigger in capacity. Most multi-user systems use magnetic tape as external storage for backup of software. Single-user systems use floppies as the backup device. This is because multi-user systems have large hard disks, which have to be backed up quickly and conveniently. Each user communicates with the system through a keyboard and a VDU – these are together referred to as the user terminal or node. A
