What is CPU

By
Central processing unit-CPU

A CPU, or central processing unit, is the brain of a computer. It is responsible for executing instructions that make up a computer program, and is the primary element of a computer system that performs most of the processing.


The CPU is a complex piece of hardware that consists of multiple parts, including the control unit, the arithmetic logic unit (ALU), and the registers. The control unit fetches instructions from memory, decodes them, and then sends them to the ALU for execution. The ALU performs the actual computation, using the data stored in the registers.


The speed and performance of a CPU is measured in terms of its clock speed, which is the number of instructions it can execute per second. Modern CPUs have clock speeds that range from a few gigahertz to several gigahertz.


There are two main types of CPUs: single-core and multi-core. Single-core CPUs have only one processing unit, while multi-core CPUs have multiple processing units, allowing them to perform multiple tasks simultaneously. Multi-core CPUs are more efficient and can improve the performance of a computer system significantly.


The design of a CPU is constantly evolving to keep up with the increasing demands of computer programs. Newer CPUs are designed to be more efficient, using less power while providing better performance. They also incorporate advanced features such as hyper-threading and multi-level caches, which help to improve the speed and efficiency of the CPU.


In conclusion, the CPU is a critical component of a computer system, responsible for executing instructions and performing most of the processing. Its design and performance are constantly evolving to meet the demands of increasingly complex computer programs.

TMA solutions 2022

By
Many undergraduates in "National Open University of Nigeria" fail in their TMAs most especially those in 100 and 200 level, and most students resort to given out their TMAs to someone else to solve them and unfortunately you are not certain that this set of people may not give you the scores you expect. TMA mean “Tutor Mark Assignment” which constitutes 30 marks while your exam is 70 marks. If you don’t score very good points in your TMAs then I am afraid to tell you it may affect your chances of getting a good result. Mind you, National Open University will only ask you to provide answers to TMAs that you will find in your course materials except in very rare cases. I have done my research and have discovered this myself and that is why I am helping students to graduate with outstanding results. However, I came to discover this secret in my 200 level and that is why I wrote this to encourage other undergraduates to do their Tutor Mark Assignment (TMA) by themselves by follo

Software Design

  In this article I will be teaching you about what design phase is all about as one of the phases of software development. Design Phase is a stage where pictorial representation of software takes place before the coding stage. The software system design is produced from the outputs of the requirements phase. That is where the details on how the system will operate are produced. This phase encompasses hardware and software, communication, software design. Meaning of software design : A software design is a definitive engineering representation of some software products which is to be produced. A design can be traced back to the customer's needs and can be evaluated for quality as against predefined condition. In software engineering context, design priorities are on four major aspect of concern: interfaces, data, components, and architecture. The design process is very imperative. As a laborer, for instance someone would not attempt to build a house without an approved bluepr

Blockchain Technology

By
Blockchain is a decentralized, distributed ledger technology that allows for the secure and transparent recording of transactions. It uses a network of computers, or "nodes," to validate and verify transactions, which are then added to a chain of blocks that make up the blockchain. Each block contains a unique code, called a "hash," that distinguishes it from other blocks on the chain and helps to ensure the security of the blockchain. One of the key features of blockchain technology is that it allows for the creation of a permanent, unchangeable record of transactions. This makes it useful for a wide range of applications, such as tracking the movement of assets, recording financial transactions, and creating secure and transparent voting systems. Another important feature of blockchain is that it is decentralized, meaning that it is not controlled by any single entity. This decentralization makes it resistant to tampering and censorship, and allows for the creati
