Nt1330 Unit 1

When building a pc, one needs to consider what they are going to use the PC for. For a college student, some uses of a desktop pc could consist of gaming, video editing, and running software. All three of these rely on each part of the computer to perform the task. One component used heavily in all three of the tasks is the CPU (Central Processing Unit). The CPU is a piece of computer hardware that

Processor: A computer processer, otherwise known as the CPU (Central Processing Unit) is a part of the computer that receives input and decides that the output will be. Many modern CPUs are capable of processing trillions of calculations per second. The speed of a processor measured by how many operations a CPU can do in one second; this is done in MHz or GHz (Megahertz or Gigahertz). A processer with the speed of 1 MHz does 1,000,000 operations per second, and a 1GHz processer does 1,000,000,000 operations per second. This is known as the clock speed.

A CPU, is what is regularly alluded to as a processor. A processor contains numerous discrete parts inside it, for example, one or more memory reserves for directions and information, guideline decoders, and different sorts of execution units for performing number juggling or legitimate operations.

CPU stands for Central Processing Unit and it’s the brain of the computer. CPU executes instructions that enable the operating system and application software to run on a system. Inside the CPU we can find three main components which are the ALU, Control Unit and memory unit. ALU stands for Arithmetic and Logic Unit and performs calculations like addition, multiplication, division and subtraction. It also compares results using “greater than”, “less than” or “equal to”. Control Unit controls the operation of the memory unit, processor and input/output units. Memory unit is where all data that the CPU may need to process is stored. The data is stored in the memory in binary form.

3.8) Short term scheduler or CPU scheduler: selects a process from the processes (that are in memory) that are ready to execute and allocates the CPU to it.

The processor has a number of cores ranging usually from 1 to 8 in domestic computers though with advancements in technology this number is sure to rise. For every core it can perform a process, so if it is a quad-core processor it can carry out four processes simultaneously , so generally the more cores the more powerful a processor is considered. Intel has hyperthreading on its new range of processors so when an application on one thread stalls or needs to get info from the RAM, the other

In Symmetric Multiprocessor systems performance is high since each processor will have its own CPU, registers and cache. The processes will be allocated to each processor separately and each process runs on its own. So, if there are 3 processes then there will be 3 CPU’s which runs simultaneously and hence all the 3 processes will be completed at the same time. But in Asymmetric Multiprocessor systems performance is not high as symmetric because the operating system can process only one request at a time. Only after the process allocated

A core is usually the basic computation unit of the CPU - it can run a single program context (or multiple ones if it supports hardware threads such as hyperthreading on Intel CPUs), maintaining the correct program state, registers, and correct execution order, and performing the operations through ALUs.

Q:1. Briefly explain following designing requirments that are required when designing the hardware and software infrastructure :

This task involves in-depth reading of the case study of Micronics Limited which will be evidenced throughout these tasks. For P5 use the suggested structure of a typical requirements specification.

CPU- the percentage of CPU time in the last second or whatever the update speed is set to.

Network requirements: - all database administrators and infrastructure ought to have a stray pieces comprehension of the topology of the system supporting the database servers on the grounds that this effects infrastructural choices.There is some analysing current database network traffic services:-

There are various types of techniques for gathering requirements for any type of organization. The best way to perform this information gathering task is to ask questions to customers. This requirements questionnaire could be the questions related to the software project. The basic purpose of these interviews is just to clarify understanding of project concerns. It is considered as most powerful technique to direct understanding of customer’s and stakeholder’s needs & expectations.

A CPU (Central processing Unit) socket is a connection that allows a computer processor to be connected to a motherboard. It is the brain of computer where most calculations take place and it is one of the most important component of the computer.
