Computer engineering involves the entire lifecycle of a computer system from conception to operation, testing and maintenance, and includes all components necessary for an application. It is an academic discipline that is concerned with providing solutions to the business of computers and information technology.
A computer system can be classified into different classes based on its purpose and function. The basic classifications include desktop, laptop and workstation. Laptop computers use a microprocessor while desktop computers use a central processing unit and are connected to a motherboard. Workstations are connected to a printer or a monitor and are used by business people in offices.
The main components of computers are the processors and the memory. The processing unit controls the flow of information in a computer. The processor contains hardware instructions that are used by the software for performing various tasks. The software contains software applications and user interface programs that allow for the efficient operation of a computer.
Computer software refers to the program written for a computer by its designers. An example of this would be software used for designing and constructing ships and submarines. Software is necessary for the effective functioning of a computer.
Computer systems use electronic circuits and wiring to store information. Electrical circuits are used to connect different parts of a computer. The software used by the computer is used to process the data entered into the system and provide useful information. The software also uses a number of software applications to perform certain tasks. There are many types of software such as desktop software, web software, database software, office applications, software used for designing and building computer equipment, and software used for software engineering.
Computers are used for the purpose of communication. Most computers today have internet capability. The computer network is one of the most important aspects of a computer’s operation. There are several types of networks and they include private, public, corporate and public networks.
Computer science is the field of study that studies the design of computers and their functions. Computer engineering has become so broad that it has many sub-fields including Information Technology, Wireless LANs, Computer Networks, Software Development, Multimedia, Mobile Computing, Enterprise Application Software and Security, Software Testing, System Design, Software Maintenance, System Analysis and User Interface Design.
Computer engineering has many areas of focus. The most important areas of focus are information technology, multimedia and communication.
Information technology involves software engineering, multimedia and networking. Networking involves the creation of connections between computers. A network consists of a group of computers connected via a network card or cable.
Multimedia involves software engineering and multimedia. Multimedia involves using video and sound recording, video and audio production, broadcasting and editing. Audio engineering includes audio software like sound card software used for making voice over IP telephony. Internet is also important area of focus.
Security involves software development and software maintenance. Software development includes the design, development and testing of security features on a computer. A software design and testing team usually consists of programmers, database developers, testers, users, testers and auditors. User interfaces are also part of this area of focus.
A system that works well should have a good user interface. A good user interface is required to allow easy operation of the computer. A user interface consists of user interface controls, menus, screens and menu bars. A system should have the ability to support a wide range of user needs and requirements.
User experience of a computer system is the way in which the computer user can understand the computer program and interact with the computer. User experience of a computer system includes designing, developing and maintaining software applications, testing software systems, designing and building hardware devices, testing hardware devices, designing and software systems, and testing data structures of data structures, and designing security methods.
A system is only successful if it meets the needs of the user. It must be efficient at the task to be done. A system should be designed in a way that it is easy to use and able to perform a certain task.
