Computer hardware is any physical device used in or with your machine, whereas software is a collection of programming code installed on your computer's hard drive. In other words, hardware is something you can hold in your hand, whereas software cannot be held in your hand. You can touch hardware, but you cannot touch software. Hardware is physical , and software is virtual.


Computer engineering CoE or CpE is a branch of engineering that integrates several fields of computer science and electronic engineering required to develop computer hardware and software.

Computer engineers are involved in many hardware and software aspects of computing , from the design of individual microcontrollers , microprocessors , personal computers , and supercomputers , to circuit design. This field of engineering not only focuses on how computer systems themselves work but also how they integrate into the larger picture. Usual tasks involving computer engineers include writing software and firmware for embedded microcontrollers , designing VLSI chips , designing analog sensors , designing mixed signal circuit boards , and designing operating systems.

Computer engineers are also suited for robotics research, which relies heavily on using digital systems to control and monitor electrical systems like motors , communications , and sensors. In many institutions of higher learning, computer engineering students are allowed to choose areas of in-depth study in their junior and senior year because the full breadth of knowledge used in the design and application of computers is beyond the scope of an undergraduate degree.

Other institutions may require engineering students to complete one or two years of general engineering before declaring computer engineering as their primary focus. Computer engineering began in when John Vincent Atanasoff and Clifford Berry began developing the world's first electronic digital computer through physics , mathematics , and electrical engineering.

John Vincent Atanasoff was once a physics and mathematics teacher for Iowa State University and Clifford Berry a former graduate under electrical engineering and physics. Together, they created the Atanasoff-Berry computer , also known as the ABC which took 5 years to complete. The modern personal computer emerged in the s, after several breakthroughs in semiconductor technology. Due to increasing job requirements for engineers who can concurrently design hardware, software , firmware, and manage all forms of computer systems used in industry, some tertiary institutions around the world offer a bachelor's degree generally called computer engineering.

Both computer engineering and electronic engineering programs include analog and digital circuit design in their curriculum. As with most engineering disciplines, having a sound knowledge of mathematics and science is necessary for computer engineers. Computer engineering is referred to as computer science and engineering at some universities. Most entry-level computer engineering jobs require at least a bachelor's degree in computer engineering or computer science and engineering.

Typically one must learn an array of mathematics such as calculus , algebra and trigonometry and some computer science classes. Because hardware engineers commonly work with computer software systems, a strong background in computer programming is necessary.

According to BLS, "a computer engineering major is similar to electrical engineering but with some computer science courses added to the curriculum". It is also important for computer engineers to keep up with rapid advances in technology. Therefore, many continue learning throughout their careers. This can be helpful, especially when it comes to learning new skills or improving existing ones.

For example, as the relative cost of fixing a bug increases the further along it is in the software development cycle, there can be greater cost savings attributed to developing and testing for quality code as soon as possible in the process, and particularly before release. Institution: Private institution such as computer engineering organizations and private companies. According to the U. Bureau of Labor Statistics BLS , "computer applications software engineers and computer systems software engineers are projected to be among the faster than average growing occupations" The expected ten-year growth as of for computer software engineering was an estimated seventeen percent and there was a total of 1,, jobs that same year.

However, some of the work will be outsourced in foreign countries. Computer engineering is generally practiced within larger product development firms, and such practice may not be subject to licensing. Processor design process involves choosing an instruction set and a certain execution paradigm e. VHDL or Verilog. CPU design is divided into design of the following components: datapaths such as ALUs and pipelines , control unit: logic which controls the datapaths, memory components such as register files, caches, clock circuitry such as clock drivers, PLLs, clock distribution networks, pad transceiver circuitry, logic gate cell library which is used to implement the logic.

Computer engineers work in coding, cryptography, and information protection to develop new methods for protecting various information, such as digital images and music, fragmentation, copyright infringement and other forms of tampering. Examples include work on wireless communications, multi-antenna systems, optical transmission, and digital watermarking. Those focusing on communications and wireless networks, work advancements in telecommunications systems and networks especially wireless networks , modulation and error-control coding, and information theory.

High-speed network design , interference suppression and modulation, design, and analysis of fault-tolerant system , and storage and transmission schemes are all a part of this specialty. This specialty focuses on compilers and operating systems design and development. Engineers in this field develop new operating system architecture, program analysis techniques, and new techniques to assure quality.

Examples of work in this field include post-link-time code transformation algorithm development and new operating system development. Computational science and engineering is a relatively new discipline. According to the Sloan Career Cornerstone Center, individuals working in this area, "computational methods are applied to formulate and solve complex mathematical problems in engineering and the physical and the social sciences. Examples include aircraft design, the plasma processing of nanometer features on semiconductor wafers, VLSI circuit design, radar detection systems, ion transport through biological channels, and much more".

In this specialty, engineers build integrated environments for computing, communications, and information access. Examples include shared-channel wireless networks, adaptive resource management in various systems, and improving the quality of service in mobile and ATM environments. Some other examples include work on wireless network systems and fast Ethernet cluster wired systems.

Engineers working in computer systems work on research projects that allow for reliable, secure, and high-performance computer systems. Projects such as designing processors for multi-threading and parallel processing are included in this field. Other examples of work in this field include the development of new theories, algorithms, and other tools that add performance to computer systems.

Computer architecture includes CPU design , cache hierarchy layout, memory organization and load balancing. In this specialty, computer engineers focus on developing visual sensing technology to sense an environment, representation of an environment, and manipulation of the environment. The gathered three-dimensional information is then implemented to perform a variety of tasks.

These include improved human modeling, image communication, and human-computer interfaces, as well as devices such as special-purpose cameras with versatile vision sensors.

Individuals working in this area design technology for enhancing the speed, reliability, and performance of systems.

Embedded systems are found in many devices from a small FM radio to the space shuttle. According to the Sloan Cornerstone Career Center, ongoing developments in embedded systems include "automated vehicles and equipment to conduct search and rescue, automated transportation systems, and human-robot coordination to repair equipment in space.

This specialty of computer engineering requires adequate knowledge of electronics and electrical systems. Engineers working in this area work on enhancing the speed, reliability, and energy efficiency of next-generation very-large-scale integrated VLSI circuits and microsystems.

An example of this specialty is work done on reducing the power consumption of VLSI algorithms and architecture. Computer engineers in this area develop improvements in human-computer interaction, including speech recognition and synthesis, medical and scientific imaging, or communications systems. Other work in this area includes computer vision development such as recognition of human facial features.

What are the differences between hardware and software?

A desktop computer is a specific type of computer that generally sits in one place, as opposed to a laptop or tablet, both of which are portable. Both hardware and software make up a desktop computer system to enable you to use it for business or entertainment. The tower or case of a desktop computer is the cabinet that houses the computer itself. Sometimes computer cases are horizontal to enable the user to fit them on a shelf more easily. However, vertical towers are the typical configuration for most desktops. Tower cases are usually made out of metal and plastic.

    There is more to a computer than this, however. The missing element is software–the instructions that tell the computer how to operate the hardware. All computers must have these two components to function. In general terms, a computer is a machine operating under the control of instructions stored in its own memory.
