Guide to buying a desktop computer

 At the speed of technology, nothing is happening everywhere like computers. Everyone has one. They are used by all classes of people for various endeavors. So are you simply buying a computer that somebody sells? Or you can do some homework and find specific specifications that make a difference to you.

At Myshopping.com.au you can compare prices of different computers from different vendors with different specifications. This guide will help you find what you are looking for.

Mac or Windows (PC)

You have to decide at the beginning why you are using the computer. This will help you make the basic decision whether you want to go to Mac or PC. With the advent of dual-core processors (Intel chips are now used on Macs), the differences are somewhat narrow. There are still some options you can prioritize for each system. Historically, Mac computers have a reputation for providing more stability with a robust operating system than Windows-based computers. For this reason, Macs are in the graphic design industry. It is the computer of choice for the music and video production industries. It inspired software developers to create professional software packages for these segments that favor the Mac operating system. They have packages that support the Windows operating system, but they are usually less powerful.

So, if you are in this industry and need your computer for this kind of business, you should consider a Mac. Macs are less prone to viruses and software errors than Windows-based PCs. At the bottom. Software support for Mac systems seems to be limited.

Another option that guides your choice is the beauty of the computer. If you have limited space, it is similar to iMacs or mini Macs for space saving. iMac's all-in-one desktop units are compact and complete with all the connections you need. However, with the wide range of models available in the compact packages and the sophisticated color combinations that match all the dೋರ್cor, the look of other brands is more to your liking. Now that you have made the basic decision, you can start comparing apples to apples.

Components of your computer

Two factors that determine the price of your computer are size (of course, that's important) and speed. These two or both dimensions are an integral part of every practical component of the machine. Naturally, most price tags go with the largest and fastest combination.

CPU

The heart of the computer is the CPU (central processing unit). You need to decide which CPU you want to run on your computer. They come from a variety of manufacturers and are currently known as Dual Core. This means that the chip has two processors. Dual core technology reduces power requirements and improves performance. Intel and AMD are the world's top two CPU manufacturers, offering different products under different names.

Current operating speeds range from 1.4 GHz (gigahertz) to 3.46 GHz. But not just with momentum. There are other considerations. Mac operating systems have a different configuration than Windows and allow you to perform many tasks faster with slower CPU speeds. Dual core chip Pentium 4 chip at 1.4 GHz offers better performance at 1.8 GHz. The 1.4 GH dual core chip used on Macs with OSX Tiger outperforms the Windows 2.0 GHz Pentium 4 processor. What do you want your computer to do before deciding on a CPU processor? You need to decide what your core software requirements are.

However, for everyday use, a faster processor provides better performance than 1.8 GHz. Celeron for a low-cost computer. Choose a Pentium 4 for a medium budget or an AMD Athlon for a big budget. Pentium Celeron; You can find computers based on Athlon or Dual Core CPUs at Myshopping.com.au and compare them with different vendors and brands using different processors.

The bigger it is, the better the performance. RAM is a system memory that allows a computer to run its programs and exchange data between hard drive and program functions. The speed of your computer's RAM to the speed of your CPU Working in media fields tend to work with very large files and require large storage space. 40G of hard drive space with a minimum of 40GB of computers on most computers today. However, this can be upgraded (usually in 20G chunks) to as much as 200G or more. The efficiency of your hard drive can also depend on its physical speed (5400-7200 RPM) and the speed at which it can transfer data between the computer's RAM and the hard drive. Faster means better performance.

REMOVABLE MEDIA

You'll want to have a CD-R or (CD-RW) drive installed on your computer, and possibly a DVD or DVD-R. A CD ROM, all that is required is a CD drive and watch DVD movies, a DVD ROM drive. However, with a CD-R drive, you can record your own data and music CDs, and with a DVD-R drive, you can burn files in a DVD format, you can store movies and data in vast quantities. The CD-RW (DVD-RW) drives allow you to use re-recordable media. Shop your media drives for what you want and what you want.

Other removable media may include flash card storage, which is usually plugged in via USB ports.

MONITORS

The monitor for your computer is integral to its function and aesthetics. If you are working in graphics you may want to stay with a CRT monitor. However most bundle offers these days are supplied with LCD monitors, which have the advantages of smaller space requirements, lower energy and offer wider screen images. However, they are often more expensive (although the prices are dropping everyday), they are often not as bright, they have limited viewing angles and sometimes require a digital interface connector.

For graphics intensive work, CRT monitors as gradients in render colors to the same capacity as LCD screens do. Once again, size matters. Bigger screens cost more than the smaller ones.

VIDEO AND SOUND

For a detailed explanation of video cards, please see the article on Myshopping.com.au Dedicated Video Cards.

The interface between the CPU and the monitor is provided by the video card. One of the basic decisions you need to make is a 3D or 2D card. Two different types of video cards come in: those that use an AGP (accelerated graphics port) on the computer motherboard and those that use the PCI bus. Data transfer rate is critical to video performance. Faster video cards use an AGP, and these proves a faster data transfer than PCI cards. Most video cards also have their own video memory installed on the card, a feature that increases a computer's memory performance. Today, these are often 128M or 256M, and can be more in the high-end cards dedicated to sophisticated video work or gaming. Video cards performance is also affected by what is known as clock speed or clock rate, with cards offering a faster speed offer faster performance.

Cheaper computers, laptops and notebooks, have an integrated graphics chip included in the motherboard instead of a discrete video card. This type of configuration is not as powerful or as fully functional as a separate video card, which allows for more comprehensive gaming, faster use of multiple monitors and faster and better rendering of images.

For a computer, it requires a sound card to record games, movies and music products. The sound card is installed by your computer. Sound reproduction processes of your computer. If you are a musician and want to record audio, then you will want to be sure that you have excellent connectivity, good midi access and at least 16-bit (CD quality) audio reproduction. Sound cards give you the possibilities of full cinema surround sound, and the many subtle effects employed by high-end games.

Nearly every computer comes with a set of stereo speakers. However it pays to have a good listen to what is buying. Make sure you listen to the program that you are familiar with (along with your own CD) and compare the sound in a quiet environment. Many speaker systems have computers that have poor frequency response and are underpowered. For desktop use that does not involve a quality listening environment. But if you want to listen to music and watch movies in full effect, then you need a good quality set of speakers. Use the search facility of Myshopping.com.au to compare specifications and prices of different speaker systems.

KEYBOARD AND MOUSE

The choice of keyboard and mouse are personal choices. Sometimes it depends on what you do on your computer, whether you have formal typing skills or a two-finger hack. Serious writers may prefer an ergonomic keyboard. Keyboards often have different clicks and responses to others. You may prefer an infrared cordless keyboard and mouse. You may prefer an optical mouse. Optical mice have no rollerball, and can be used on most flat surfaces, but they are more expensive.

CONNECTIVITY

Today, connectivity is everything. Your computer can have wireless connections to all your peripherals: printer, scanner, and other computers. Having an onboard modem is only really important if you are using a dial up internet connection. Broadband modems tend to be peripherals and you can connect via USB, wireless or firewire. This is how you will pay for the internet and other peripherals. Plug it in or unplug it to your computer. Some sound cards have all the connections you need with a front face panel. The USB ports on Macs are conveniently located. Many PC manufacturers have found that some people have access to their computers easily.
