How to Buy a Computer

I will also consider the following components; those essential for the computer to work faster, and more efficient. They are as follows: Central Processing Unit (CPU) – System Memory (RAM) – Storage Device(s). The following is a detailed look at the CPU, RAM, and Storage devices; the important components that you should consider when purchasing a PC. Computer systems, particularly the higher-end models, come in several Configurations: desktop, mini tower, or tower. The configuration you chose should depend - to some extent - on the amount of expansion, (if any) you may want to plan for in the future.

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. Memory There are four types of memory. These are the RAM, ROM, EEPROM and the Bootstrap loader. The RAM, also known as Random Access Memory, is the temporary space where the processor places the data while it is being used.

On the other hand, the gaming machine for playing that requires faster processors, high-end video cards, large amounts of memory, and will be able to run any software the user desire. The user needs the following tools to build a computer; they are Philip's head screwdriver, flat head screwdriver long nose pliers and flash light. User must determine if the user wants a desktop, tower cases. User will want to allow for expand unless the user is building a little case. However, be sure to get the case that will fit the where the user plans to put it.

A computer is different from other machines because it needs a program to tell it what to do. Some companies make computers, while others write programs. This means if a certain kind of computer becomes popular, more programs will be written for it, and this will make the machine even more popular. Eventually one computer has become the standard. In the real world this computer is the IBM clone.

Accessing information from these devices is extremely fast and acts like an extension of the hard disk. Conclusion Choosing a computer for personal or business use can be overwhelming. The first decision to be made is how this computer will be used. How the data will be input, processed, and used is the key to finding a perfect fit system. Knowing how to combine speed, storage, input and output devices with ultimately determine what machine an individual or business should choose.

Introduction This paper will take a closer look at data input and also data output considerations. There are many different choices when it comes to data input/output options. While it is good to have many choices, there are usually some considerations that are required to make the best possible decision. The second section of this paper will concentrate on the difference between primary and secondary storage. Lastly, the different roles of computer components and their impact on overall computer speed will be explored.

Memory - This is very fast storage used to hold data. It has to be fast because it connects directly to the microprocessor. There are several specific types of memory in a computer: Random-access memory (RAM) - Used to temporarily store information that the computer is currently working with Read-only memory (ROM) - A permanent type of memory storage used by the computer for important data that does not change Basic input/output system (BIOS) - A type of ROM that is used by the computer to establish basic communication when the computer is first turned on Caching - The storing of frequently used data in extremely fast RAM that connects directly to the CPU Virtual memory - Space on a hard disk used to temporarily store data and swap it in and out of RAM as needed Motherboard - This is the main circuit board that all of the other internal components connect to. The CPU and memory are usually on the motherboard. Other systems may be found directly on the motherboard or connected to it through a secondary connection.

They require a CPU to calculate for them. But recently, a company named Accelereyes has been working to translate said programs in a program they are creating called Jacket. It would be used to compile the functions of a CPU into code that a GPU can understand. To conclude, the differences between a GPU and a CPU are numerous. A GPU can do certain computations faster than a CPU can do the same computations, it can display images onto the monitor for the user to see, and it can store data onto its RAM for temporary storage and for later use.

The computer has two main data storage types, which include Primary storage and Secondary storage. There are two classifications of primary storage, which are directly accessible to the Central Processing Unit, commonly referred to as, the Random Access Memory (RAM) and the Read Only Memory (ROM). The RAM which is the working memory has two main forms namely, static RAM (SRAM) and dynamic RAM (DRAM). The SRAM is faster, expensive and uses less power than the DRAM. The CPU continuously and constantly reads instructions from the RAM.

Choosing a Computer System When considering the purchase of a system there are several components involved and those components are software, hardware, data, procedures and people. (Kroenke, 2008, pg.5) Also when purchasing a new computer system it can be extremely unnerving and costly. When thinking of the hardware of a computer system one would look for the following components: the size of the monitor, the CPU type and/or speed and the warranty that generally is offered with a new system. In terms of a computer monitor, it is the most important part of a computer because it is the part that we rely on and use the most. There are several types and sizes of monitors that you can use with a computer system, a CRT or a flat panel monitor.
