The Basic Computer Hardware Central Processing Unit: The central unit is the basic part of the computer and includes all the main computer parts. It is the heart of the computer system. It is responsible for executing, or running the software. The software programs are translated into a series of codes made up of 1s to 0s that the CPU can understand. Every code means a certain operation should take place. A CPU has various discrete units to help it in these tasks for example there is an arithmetic and logic unit(ALU) that takes care of all the math and logical data comparisons that need to performed. A control register makes sure everything happens in the right sequence. The motherboard is the main circuit board inside the PC. All other components are either slotted into or soldered to this board. Microprocessors: Microprocessors are different to one another according to the manufacturer and technical specifications. The most important technical specifications of microprocessor are the type and processing speed. The type of microprocessor is defined by the internal structure and basic features .The microprocessors communicate with the rest of the system by means of buses. Buses are sets of parallel electronic conductors set of wires or tracks on the circuit board.
Computer hardware engineers research, develop, and test computer systems and components such as processors, circuit boards, memory devices, and many more (Bureau of Labor Statistics). They design new computer hardware, create blueprints of computer equipment to be built. Test the completed models of the computer hardware that they design. Update existing equipment so that it will work will new software. Oversee the manufacturing process for the computer hardware. Maintain knowledge of computer engineering trends and new technology(Bureau of Labor Statistics).
Building a computer can be a useful skill in today's world. It allows you to
The motherboard is the main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard's chipset. On most PCs, it is possible to add memory chips directly to the motherboard. You may also be able to upgrade to a faster CP by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely. (Glossary)
A clock in a computer is kept by a master clock which delivers alternating signals. The clock phase has two phases, a tick and a tock. The tick tock phase is represented by a binary signal. The signal is from the hardware’s circuitry and it is simultaneously broadcasted to all the sequential chips in the computer. The counter is a sequential chip that has an integer that increments every time unit that goes by. As expected, the counter is an extremely important part in digital architectures. In logic programs, a counter can be implemented, which will add a constant. So you can manipulate the standard register (Nisan & Schocken, 2005). It is located in the control unit of the computer. The program counter tells the control unit the instructions it receives from the RAM. So it connects the Control Unit to the
A microcontroller is a small compact computer used to manage the operations of the systems inside motor vehicles, robots, mobile radio transceivers, home appliances, and various other devices (Techtarget, 2014). It is typically composed of a Central Processing Unit, a memory and input or output pins that look like minute hollow blocks (Quinstreet Inc, 2014). It originated way bay back from the 1970s when engineers, designers, and architects were finding a way on how to create the world’s first microprocessor. Intel paved its way to the technology world by inventing the microprocessor in 1971 but two engineers made the larger impact by inventing a more advanced electronic component – the microcontroller. In 1971, the microcontroller was invented by two engineers from Texas Instruments – Gary Boone and Michael Cochran (Aycock, n.d.). After its invention, the microcontroller m...
The first microprocessor was developed by a small company called Intel (Integrated Electronics) in the early 1970s. But it faced no consumer market so they decided to market the chipset as “general purpose” microprocessing system where digital logic chips would have been used. This idea was a success and the Intel team developed 4 bit microprocessor called the 4004.

System units are commonly mistaken as the Central Processing unit (CPU). System units sometimes called “computer chassis”, “base units” or “Tower cases” however are simply the housing for the integral parts of a computer. System units usual house all components of a computer excluding the monitor, Keyboard and mouse. System Units are a very simple component of the computer because they do none of the actual computing. They are usually just a square or rectangular prism made of some type of plastic or metal that hold all of the vital parts of a computer in a secure manner. Other than that there is not much to be said about the system unit.
Computer hardware: With the on-going developments in the field of computer system design and architecture, peripherals and processors, hardware helps computing merge seamlessly into our lives. With primary memory capacity reaching up to more than 64 Gigabits, to high resolution LED-displays; hardware accommodates the ever increasing needs of ubiquitous computing.
We have the microprocessor to thank for all of our consumer electronic devices, because without them, our devices would be much larger. Microprocessors are the feat of generations of research and development. Microprocessors were invented in 1972 by Intel Corporation and have made it so that computers could shrink to the sizes we know today. Before, computers took a room because the transistors or vacuum tubes were individual components. Microprocessors unified the technology on one chip while reducing the costs. Microprocessor technology has been the most important revolution in the computer industry in the past forty years, as microprocessors have allowed our consumer electronics to exist.
It’s prime role is to process data with speed once it has received instruction. A microprocessor is generally advertised by the speed of the microprocessor in gigahertz. Some of the most popular chips are known as the Pentium or Intel-Core. When purchasing a computer, the microprocessor is one of the main essentials to review before selecting your computer. The faster the microprocessor, the faster your data will process, when navigating through the software.
A computer is a combination of several parts. These parts are Random Access Memory (RAM), a Central Processing
In designing a computer system, architects consider five major elements that make up the system's hardware: the arithmetic/logic unit, control unit, memory, input, and output. The arithmetic/logic unit performs arithmetic and compares numerical values. The control unit directs the operation of the computer by taking the user instructions and transforming them into electrical signals that the computer's circuitry can understand. The combination of the arithmetic/logic unit and the control unit is called the central processing unit (CPU). The memory stores instructions and data.
1. There have been a lot of developments in microprocessors since the 286 chip. The 286 CPU are no longer sold and are very rarely found in commercial use today because of its running speed, which is between 10MHz to 20MHz. This processor has a 24-bit address bus, and is able to address up to 16 million different address locations. It also has two operating modes, which are real mode and protected mode. The real mode is basically for normal DOS operations and it uses only 8086 code (8086 was the previous CPU). When it was in protected mode the CPU is able to access beyond the 1mb address limit and employed its added features, which were intended for multi-tasking operations such as Windows, but this CPU is not powerful enough to carry out these multi-tasking operations. The 286 came with a bus width of 16-bit internal, 24-bit address, and 16-bit external, with an external speed of between 6MHz – 25MHz, and an internal speed of between 6MHz – 25MHz.
CPU Stands for "Central Processing Unit." The CPU is the primary component of a computer that processes instructions. It runs the operating system and applications, constantly receiving input from the user or active software
