In broad terms, the performance of a computer depends on four factors: the speed and architecture of its processor or "central processing unit" (CPU), how much random access memory (RAM) it has, its graphics system, and its internal hard drive speed and capacity. The components of your PC must work together in order to bring you the fastest, most reliable performance. When it comes to high computer performance, one or more of the following factors might be involved: However, they can negatively impact PC performance if they are allowed to become out-of-date. Overall, the performance of a computer is dependant on how well it works together as a whole. Too much heat adversely affects the working capacity of various components of the computer. And the latest operating system can guarantee the security, speed and efficiency of the computer. Computer System: A computer is a machine that can be programmed to accept data, process data into useful information and store it for later use. Why? Here are three examples of how the CPU clock speed and word length can vary: The 8088 processor has a clock speed of 4.77 MHz and has an 8-bit word length. The capacity of a personal computer hard disk is from 160 GB to 2TB and more. This is only true to a certain extent. The above five performance factors (Ic, p, m, k & t) are influenced by these attributes: Cache & memory hierarchy X X CPU implementation & control X X Compiler technology. The hard disk speed of different hard disks is not consistent because they vary by manufacturer, drive type and the use of the hard disk. It is obvious, that all major computer components such as CPU, memory and IO devices together affect computer's performance. It basically depends on response time, throughput and execution time of a computer system. That’s why we’ve put together this guide. It’s worth learning what each hardware component in a computer does, and how it can affect your game play. Topic introductions & revision for GCSE Computer Science. A computer with more memory often performs better for a longer time than a computer with less memory. In broad terms, the performance of a computer depends on four factors: the speed and architecture of its processor or "central processing unit" (CPU), how much random access memory (RAM) it has, its graphics system, and its internal hard drive speed and capacity. Gaining an understanding of what each specification means, and what each part does, is the goal of this section. Asynchronous interfaces utilize self-timed protocols when sending data. This is the processor's built-in code that tells it how to execute its duties. It basically depends on response time, throughput and execution time of a computer system. If there is an insufficient amount of RAM in a system, … 2) Describe how the following hardware components affect the performance of a computer system used to manipulate digital graphics: • hard drive • … It’s worth learning what each hardware component in a computer does, and how it can affect your game play. This means that the more applications that are running the slower the computer will perform. If the Clock speed of the CPU is fast then definitely the performance of the computer will be affected positively, in other words the computer will carry out processing functions at a faster pace.2) The size of the RAM (Random Access Memory)The RAM is referred to as the active part of the computer. Slow RAM or hard disk is going to be a bottleneck for fast CPU. Instruction Set This is the processor's built-in code that tells it how to execute its duties. … It executes user processes and interacts with other resources of your system. There are many hardware factors that can limit the overall system performance: The speed and width of the system's address and data buses. You don't have to be an IT expert to learn the basics of what computer parts do and what they look like. The development of computer systems in respect of hard- and software is accompanied by performance measurements and modeling since the 1960s However, only a small fraction of the research work is applied in the field Ferrari (1986): The study of performance evaluation as an independent subject has VGA is essential to get the video output … Because if you plan on playing a lot of different games and you haven’t got the best computer, it’s pretty likely that you might run into performance issues (like lag, low frame rates, or slow load times) at some point. They include: the speed of the CPU, the space on the hard disk, the size of the RAM, the type of the graphics card, the speed of the hard disk,, if the computer is multitasking, the defragmenting files.1) The speed of the CPUThe speed of the CPU is also known as the clock speed of the CPU. If you’re building a computer, however, it can be hard to know what to pick or why. But together with processor architecture, it does affect performance across a given line of CPU's. Your computer can be thought of as an orchestra, moving data through its various components and performing calculations. Skip to content. Spyware is one of the leading causes of a slow computer.
