Discuss the organization and functions of ALU or Arithmetic & Logic Unit

Arithmetic and Logic Unit (ALU): Arithmetic and Logic Unit is a like a calculator to a computer. ALU performs all arithmetic operations along with decision making functions. In modern CPU or Microprocessors, there can be more than one integrated ALU to speed up arithmetical and logical operations, such as; integer unit, floating point unit etc. …

What are the different generations of computer? Explain

Computer systems reached today’s modern age step by step, these steps are called generations. In each generation computers with new features and functions starts to get the market and the older computers slowly gets replaced. IBM company started categorize the development of computers into generations, though not everyone in the industry including users will be …

How software engineering is different from other types of engineering?

Software project management is an essential part of software engineering. However, good management won’t guarantee success, but bad management results in project failure. Software managers are responsible for planning and scheduling development. They supervise the work to ensure that it is carried out to the required standards and monitor progress to check that the development is on time and within budget. Software engineering is different from other types of engineering in a number of way which particularly makes software engineering difficult.

Explain an example of Dry Cell or Short note on Leclanche cell.

Example of Dry Cell – Leclanche Cell: The most common example of dry cell is Leclanche cell invented by French scientist Georges Leclanche. We use to call it a battery. It has a cylindrical Zn container which works as the anode. At the center of the Zn container a carbon or graphite rod is placed …

Nature of bonding and properties of certain solids.

Diamond Diamond is an allotrope of carbon. Due to difference in bonding in its structure, it looks quite different from the other allotropes. Each carbon atom of diamond is sp3 hybridized. The four sp3 orbital arrange themselves in the four corners of a tetrahedron. Each orbital forms a bond with an orbital of another carbon …

Briefly explain the formation of dimmers and trimmers.

Some compounds like hydrogen fluorides, ethanoic acids, benzoic acid form dimmers or trimmers by joining up of their two or three molecules by H-bonding. Sometime, due to the formation of these dimmers or trimmers the molecular weight of these compounds appears to be doubled or tripled. That is, ethanoic acid has molecular weight of 60, …

What is operating system? What are the purposes, goals and roles of operating system.

Operating System An operating system is an intermediary program between computer user and the computer hardware. This computer user can also be just another software running on the operating system or another computer or device. So basically, operating systems are computer programs that let other computer programs or humans communicate with the hardware of the …
