Computer Engineering A Brief Introduction

What do computer engineers do?  They repair computer sets.  They fix the computer when it is down.  They arrange the computer and Internet system of a university campus. JUST KIDDING!  Computer engineering deals with the design of computers and computer systems. This may involve the design of new hardware, the design of PDAs or the use of computers to control an industrial plant.

 Computer engineers usually have training in electronic engineering, software design and hardware- software integration instead of only software engineering or electronic engineering.

core knowledge areas of computer engineering  an algorithm is an effective method for solving a problem using a finite sequence of instructions. Algorithms are used for calculation, data processing, and many other fields effective methodcalculationdata processing effective methodcalculationdata processing  Algorithms Algorithms

Computer Architecture  It can be defined as the science and art of selecting and interconnecting hardware components to create computers that meet functional, performance and cost goals.

Database  A database is a collection of information that is organized so that it can easily be accessed, managed, and updated.

Database Sample

Digital Logic  Digital electronics are electronic systems that use digital signals. electronic digital signals electronic digital signals  Why do we use digital signals?

 It is simply because we can reproduce an analog signal (electromagnetic wave) on an electronic device by using 0`s and 1`s. That is we can represent an analog signal with digital entities using Boolean logic functions.

Digital Signal Processing  DSP is concerned with the representation of the signals by a sequence of numbers or symbols and the processing of these signals. signals  DSP includes subfields like: audio and speech signal processing, audiospeech signal processingaudiospeech signal processing digital image processing, signal seismic data processing, etc. digital image processing, signal seismic data processing, etc.digital image processingdigital image processing

Embedded Systems  An embedded system is a computer system designed to perform one or a few dedicated functions. computer  An example is an ADSL Modem/Router

ADSL Modem/Router  Number 4 is a Microprocessor  Number 6 is a RAM  Number 7 is A Flash Memory

Operating System  An operating system (commonly abbreviated as either OS or O/S) is an interface between hardware and user. An OS is responsible for the management and coordination of activities and the sharing of the resources of the computer.

Computer Programming  Computer programming (often shortened to programming or coding) is the process of writing, testing, debugging/troubleshooting, and maintaining the source code of computer programs source code computer programssource code computer programs

The Source Code  In computer science, source code (commonly just source) is any collection of statements or declarations written in some human- readable computer programming language. Source code allows the programmer to communicate with the computer using a reserved number of instructions. computer sciencehuman- readableprogramming languagecomputer sciencehuman- readableprogramming language

The Source Code

Software Engineering  Software engineering is the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software. software

Integrated Circuits  In electronics, an integrated circuit (also known as IC, microcircuit, microchip, silicon chip, or chip) is a mini electronic circuit consisting mainly of semiconductor devices that has been manufactured in the surface of a thin substrate of semiconductor material. electronicselectronic circuitsemiconductor devicessubstrate semiconductorelectronicselectronic circuitsemiconductor devicessubstrate semiconductor

VLSI Design  VLSI: Very Large Scale Integration  Very-large-scale integration (VLSI) is the process of creating integrated circuits by combining thousands of transistor-based circuits into a single chip. integrated circuitstransistor integrated circuitstransistor

An Example of VLSI  The microprocessor is a VLSI device microprocessor

Profile of an Computer Engineer  antisocial.  numb=devoid of emotion.  nerd=socially unattractive person, devoted to intellectual and academic pursuits.
