In an ever-growing technologic world the need for a computer becomes almost a necessity than a luxury. With so many options out in the marketplace it can get overwhelming and exhausting to know what to look for when purchasing a computer. I would put a sentence showing why it is confusing, like I described in your notes. So you might ask yourself how do I go about buying a computer and what should I be looking for? The components of a computer and understanding their function are the main determining factors when looking to make a purchase. Starting with the most important component that affects not only performance but also cost is the video card. The video card is responsible for everything that is displayed and how fast it can display programs; this is referred to as the FPS or frames per second that the video card can display. With this responsibility a video card determines if you want fast smooth graphics at a greater cost for gaming or a cheaper solution if only being used for word processing and Internet usage. The size measured in megabits (MB) and speed of memory measured in megahertz (Mhz) in the video card will directly affect the cost and quality of the computer being purchased. The processor is the next most important part to look at when purchasing a computer. So what does the processor do exactly? The processor is the component that is most commonly referred to as the “brain” of the computer and is responsible for processing all the information. The processor’s value is determined by the speed in which it can process the information represented in a gigahertz (GHz) value. Processors also come with multiple cores, (such as A or B etc).

The peripherals however should always be checked for compatibility with the operating system that is on the computer and software for which it will be used. (mention at the start of the paragraph what peripherals are, like Mouse, keyboard, etc. then give the examples of use) The ports available on a computer are important to look at when purchasing computer. Ports can range from Ethernet for networking, video input/output for editing or recording, USB for plugging in any peripherals, and card slots for a media interface. Computers come standard with most port listed above however they should still be checked when purchasing. Ports will allow upgrades to be done to the computer via PCI ports by allowing cards to be added increasing areas of the computer such as video processing, network capabilities, and wireless connectivity.
Whenever you press a key, click the mouse, or start an application, you're sending instructions to the CPU. The CPU is generally a two-inch square with a silicon chip located inside. The CPU fits into the motherboard's CPU socket, which is covered by the heat sink, an object that absorbs heat from the CPU. A processor's speed is measured in megahertz (MHz), or millions of instructions per second; and gigahertz (GHz), or billions of instructions per second. A faster processor can execute instructions more quickly. However, the actual speed of the computer depends on the speed of many different components—not just the processor.
10. The main qualities to look for in an LCD monitor are price, size, brightness, contrast ratio and resolution.

With the growth of technology it allowed for the growth of available information as well as advanced ways of communication. The initial intention of computers and technology was to serve the working or business class, to help companies create better products for their consumers. Next, the tools that were previously only used to facilitate businesses then started becoming more domestic, little by little people and families began owning desktop computers in their homes .By innovating t...
First of all, for the working peoples, the appearances of computer technology bring up a convenient
A CPU has various discrete units to help it in these tasks for example there is an arithmetic and logic unit(ALU) that takes care of all the math and logical data comparisons that need to performed. A control register makes sure everything happens in the right sequence. The motherboard is the main circuit board inside the PC. All other components are either slotted into or soldered to this board.
RAM is used for memory caching, which means when the computer’s in operation, programs use this hardware for quick access and has memory saved temporarily for applications that’s deleted once the computer’s powered down. A CPU is what performs the large part of information processing in the computer, this tells what each part should be doing and it also proccesses requests; whether it be to turn on a cooling fan or to accept information to provide processing for words. It’s very important that the CPU is cooled well as it generates a lot of thermal energy. This heat is dissipated using a CPU cooler which often consists of a heatsink and fan. Newer technology is using liquid cooling and a radiator, which is a quiet solution to keep the CPU cool. The GPU is what processes graphics to create a display. Some graphics cards are powerful enough to provide viewing in multiple displays. A higher performance graphics card requires direct connection to the power supply as the motherboard can’t keep up with the power consumption of the card. Graphics cards can be combined to work together to process graphics. A cable linking
This motherboard has Universal Serial Bus (USB) 2.0. This gives the advantage of high-speed transfer between external sources such as video cameras, digital cameras, scanners, audio recorders, and any other possible external components. USB 2.0 is faster than fire wire, which is currently the most widely used transfer hardware.
CPU Stands for "Central Processing Unit." The CPU is the primary component of a computer that processes instructions. It runs the operating system and applications, constantly receiving input from the user or active software
The motherboard is the main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard's chipset. On most PCs, it is possible to add memory chips directly to the motherboard. You may also be able to upgrade to a faster CP by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely. (Glossary)
A processor is the chip inside a computer which carries out of the functions of the computer at various speeds. There are many processors on the market today. The two most well known companies that make processors are Intel and AMD. Intel produces the Pentium chip, with the most recent version of the Pentium chip being the Pentium 3. Intel also produces the Celeron processor (Intel processors). AMD produces the Athlon processor and the Duron processor (AMD presents).
The computer has progressed in many ways, but the most important improvement is the speed and operating capabilities. It was only around 6 years ago when a 386 DX2 processor was the fastest and most powerful CPU in the market. This processor could do a plethora of small tasks and still not be working to hard. Around 2-3 years ago, the Pentium came out, paving the way for new and faster computers. Intel was the most proficient in this area and came out with a range of processors from 66 MHz-166 Mhz. These processors are also now starting to become obsolete. Todays computers come equipped with 400-600 Mhz processors that can multi-task at an alarming rate. Intel has just started the release phase of it’s new Pentium III-800MHz processor. Glenn Henry is
It’s prime role is to process data with speed once it has received instruction. A microprocessor is generally advertised by the speed of the microprocessor in gigahertz. Some of the most popular chips are known as the Pentium or Intel-Core. 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.
In the year 1977 computers went on sale for the national public. Today in the year 2004 computers with connection to the internet are an essential item to have in the household. Accountants and typists are no longer the only ones buying computers. Age does not matter. Everyone needs a computer in the household. Computers help all kinds of people. Meeting different people’s needs, therefore computers are a useful tool for all age groups. Children, teenagers, adults, and senior citizens all can use the same computer, but they all use the computer for a different purpose.
Input is really important for the computer. Through this device, users are allows to enter data or instructions into a computer. It changed something on the screen through the response. There are many kinds of input device for users to select depending on their application to get the result they want. There are many input technologies, for example, keyboard, pointing device, trackball, touch screen, touchpads and audio input. These devices can help users to connect with computer system directly.
