Computer hard drive buying tips

Computer hard driveWhen purchasing a hard drive, it is important to understand and verify the hard drive is suitable for your uses and has or does not have the options you may or may not need. Unfortunately, with hard drive technologies frequently changing, it is can sometimes be confusing and frustrating when looking to purchase a hard drive.

This document covers all considerations you should think about when thinking about upgrading or buying a new computer hard drive.

Adding a new drive

If you are adding a new hard drive because you need more disk space, and you have a desktop computer, a new hard drive can be added without replacing the old drive.

The benefit of adding a new hard drive is that you gain additional storage without having to erase any of your existing files or reinstall any of your programs.

Replacing existing drive

If you have a laptop computer or want to replace an older hard drive (HDD) with a new solid state drive (SSD), keep in mind that anything on the drive will be lost. While it is possible to transfer all of the data from one drive to another drive,

Computer battery buying tips

Main batteries

Laptop batteryThe main battery is the battery used to power laptop computers. When looking to purchase a new main battery from a third-party, make sure you’re getting the correct battery. Verify the below specifications either from the bottom of the battery or from the computer manufacturer.

  • Type – Get the right battery: Nicad, NiMH, or Li-ion.
  • Manufacturer – Some portables may use a certain manufacturer of battery. Verify if a third-party manufacturer’s battery was used. Also, make sure the battery is not proprietary and could be purchased from a third-party.
  • Voltage – Verify the Voltage of battery; this amount can vary depending on the battery.
  • mAH – Verify the mAH of the battery; this amount can vary depending on the battery.

Warranty

Before purchasing the battery, see if the battery comes with any warranty and how long the warranty may be. This makes things easier if it is defective, since you may be able to return the battery for a new battery or for a refund.

Prices

Prices can vary depending on quantity of batteries, size, and the age of the laptop. Below is a list of the most popular batteries and their price

Network equipment buying tips

belPurchasing network cards and accessories for a network, for many, is a confusing and frustrating task. Below we have listed recommendations and considerations to look at when purchasing a network card or accessories for a network.

Connection types

When purchasing a network card, look at the available connections that card allows. Today, this is not as important as it has been in the past as today many networks are only using RJ-45. If your network utilizes a different interface, such as Coax, verify the card you are planning on purchasing has this connection.

Connection speed

Connection speed is an important consideration when looking at purchasing a network card. Today, the majority of networks and cards are found in 10 Base or 100 Base, 100 Base being the faster of the two solutions. While slightly more expensive it is recommended that all users looking to buy a network card purchase 100 Base network cards as these cards, if needed, can be switched down to 10 Base.

Card interface

The interface that the card connects to is also an important consideration. Below is a listing of the

The top 10 things to consider when buying a new laptop

When people ask us which laptop is best for their needs, the first thing we tell them is that there is no clear answer. There are too many different types of laptops, and different price categories to suit them. However, we do give people a checklist that they should consider before splurging on a new device.

1. Size: If portability is your main concern, then you need to consider a notebook that has a small-ish screen and a light weight. Any laptop marketed as an Ultrabook should fit your bill here, as they are designed to be slim and light. More to the point, though, look for a laptop with a screen that’s 12.5-13.3 inches in size, and a weight that is from 1-1.5kg.

2. Screen quality: You’ll be staring at your laptop for many hours every day, so you want to make sure you get a screen that is comfortable to look at. Many laptops these days also have touchscreens, which means they are glossy. Glossy screens lead to reflections, so consider a laptop that doesn’t have a touchscreen.

Next, look at the resolution. A 1920×1080-pixel resolution (aka Full HD) should be considered if you want plenty of space to line up

9 Key Things to Know Before You Buy a New Computer

Buying a computer is no easy task, and with the cost of many of the machines out on the market today, you want to make sure you’re making the right purchase so you don’t blow your money on something that stops meeting your demands within a year. Not all machines are created equal, and unless you’re pretty familiar with computer hardware, you might have a hard time determining just how unequal they are. Of course, not all computer users’ needs are equal, so you might not need certain things included in a computer that could be pushing up the price.

This guide should help you get a better understanding of what all the components of the computer will mean for you and make it easier to decide what you want, need, and which elements to prioritize so you get the right computer for you and don’t spend any more money than you must.

1. Desktop or Laptop?

This is probably one of the simplest choices to make and can have a big impact on the overall cost of your computer, including expenses that might not come right at the time of the purchase. In general, if a laptop and desktop are

Computer printer buying tips

Purchasing a printer can be a daunting and sometimes confusing task. Below is additional information that can help you with your purchasing decisions.

Technology

The first and foremost important consideration to consider when purchasing a printer is the technology the printer utilizes to print. Today, ink jet and laser printers are the two most popular printer technologies.

Ink Jet – Inkjet printers are an affordable and effective solution for home users and home businesses.

Laser – Laser printers are a recommended solution for businesses or networks that require speed and efficiency, and high quality resolution.

  • Inkjet vs. laser printer.

Resolution

Resolution on a printer is measured by the amount of dots per inch a printer is capable of printing. When looking at purchasing a printer, it is important to look at the DPI the printer is capable of printing.

It is also important to know that some printer manufacturers may generate their own methods through software for increasing their resolution.

Speed

Speed is another important consideration when looking at computer printers. The speed of a printer is rated in PPM, or pages per minute, and rate anywhere between 4 and 10+ PPM, depending on several factors such as if it is Black and

Computer CD buying tips

Purchasing a CD-ROM drive is a relatively easy task but can involve some considerations when purchasing.

Technology

Before considering purchasing a CD-ROM, it is also good consider the other available options.

Server buying tips

Purchasing a server for any business is a very big decision, and if not done properly, can reduce productivity or cause loss of money in the business. Below is information and help for what to look out for when purchasing a computer server. It is important to also note that every business is unique and may require more or less of what is listed below.

New vs. Used

Purchasing a new or used server or server equipment can be a method of saving the company additional money; however, it can cause lost money if that hardware or server does not meet the company’s needs. When looking at purchasing a used main server or file server for a computer network, ensure that the server is going to meet the company’s needs as far as performance and reliability. Unless the perfect used solution is found, we highly recommend purchasing a new main server, file server, network server or database server, as it has the latest hardware innovations as well as have a warranty, which allows parts to be replaced or repaired within a short period of time, keeping the network up and running.

However, other servers such as a print server or

11 Modern Minimalist Computer Desks

Recently I set out to find a new desk for my computer to rest on and came across a lot of ideas that I thought were worthy enough to share. Actually the search was tough. I mean, I know there would be a lot of people out there who would be happy with huge desks that house a nook for every peripheral… (like the one below)

but somehow they just don’t work for me. Design wise, I am more of the minimalist so naturally the ones I tend to like also favour this type of style. These minimalist computer desks we are going to feature are light weight, easy on the eyes and most of them are as sleek as the technology they are designed to hold.

OneLessDesk from Heckler Designs has a 2 deck design and takes up merely 12 inches of space when put away. The company’s pitch for the product actually sounds convincing.

At one time, you needed a desk that could fit a mountain of paper, a two-foot-deep monitor, printer, and a CPU the size of a Labrador. Today, your computer is an inch thick. You have moved forward. It’s time

Computer sound card buying tips

When purchasing a sound card, there are several factors that can complicate and sometimes not allow you to install your sound card. Before purchasing a sound card, it is important to take the following into consideration.

Interface

Ensure that you have the available connection on the computer. Sound cards are available as both PCI and ISA.

PCI – Today, most cards available are PCI; if you plan on using your sound card for such things as playing games and watching DVD movies, it is recommended you at least get a PCI sound card.

ISA – Today, ISA cards are relatively cheap sound cards, which allow users that may not have as much money to have sound on the computer. In addition to being a cheap sound card, purchasing an ISA sound card will keep an additional free PCI slot available.

In addition to verifying your computer has the available connections, it is also important to look to see if your computer has a sound card that is built onto the Motherboard. Verify that this sound card can be disabled or will be disabled when the new sound card is installed. Additional information about on-board audio can be found in document

Computer flat panel buying tips

Flat Panel is a relatively new technology when compared to the CRT or standard monitor technology and is now available for desktop computers. With new technology comes new important considerations to look at when purchasing a flat panel solution.

Technology

Before looking at what configurations you need to look for when purchasing a computer Flat Panel, it is important to know if you want a CRT or a Flat Panel and LCD monitor.

CRT Today, one of the most commonly used technologies for computer monitors. CRT, or Cathode Ray Tube, is a technology much like what you will find on most TVs. CRT monitors are an affordable solution but are bulky and very heavy.

Tips on buying a monitor can be found on our Monitor buying tips section.

LCD LCD, or Liquid Crystal Display, monitors are similar to what is found on portable computers. LCD monitors overall display much sharper of an image, are lighter and more space efficient; however, they are much more of an expensive solution for desktop displays.

Size

Dimensional Size When looking at LCD and Flat Panel displays, one of the most noticeable and considerable reasons for purchasing a Flat Panel is its size. As you will

What is Graphics?

Pictures on a computer display or the process of creating pictures on a computer display. The term came into use when there was still a distinction between computers that could display only text and those that could also display pictures. This distinction is lost now that almost all computers employ a GRAPHICAL USER INTERFACE.

Since a computer can ultimately deal only with binary numbers, pictures have to be DIGITIZED (reduced to lists of numbers) in order to be stored, processed or displayed. The most common graphical display devices are the CATHODE RAY TUBE inside a monitor, and the PRINTER, both of which present pictures as two-dimensional arrays of dots. The most natural representation for a picture inside the computer is therefore just a list of the colours for each dot in the output; this is called a BITMAPPED representation. Bitmapping implies that each dot in the picture corresponds to one or more bits in the computer’s video memory.

An alternative representation is to treat a picture as if it were composed of simple geometric shapes and record the relative positions of these shapes; this is called a vector representation (see more under VECTOR GRAPHICS). A typical vector representation might build up a

Personal Computer

A computer is a machine that can handle and manipulate data in accordance with the instructions, and is also able to generate visible results on a screen or monitor. Different computer do different kinds of work, a small computer that has been designed to be used by one person, at home or in an office. It is often simply called a PC.

What is a personal computer?

A personal computer is a computer small and low cost, which is intended for personal use (or for use by a small group of individuals). The term “personal computer” is used to describe desktop computers (desktops). It is often shortened to the acronym PC or microcomputer, whose meaning in English is “personal computer”. It is a very common type of machines.

Personal Computer (acronym PC) consists of a Processor (CPU), central processing unit (CPU) contains the arithmetic, logic, and control circuitry on an single (IC) integrated circuit; two types of memory, main memory, such as RAM, and ROM, magnetic hard disks (HDD) and compact discs and various input/output devices, including a display screen, keyboard and mouse, modem, and printer.

Computer case buying tips

Purchasing a computer case is not something to consider if you are buying a computer from an OEM such as Dell or Hewlett Packard. However, for those building a computer it can be an important consideration. Below is a listing of different considerations to look at when buying a computer case.

Color and case type

Today, there are a wide variety of computer case colors and case sizes for the PC. When looking at the case, consider the color of the case and its size. Most cases come in either urban white or white. Additional information about the computer chassis including the color and size can be found on our chassis definition.

Location and size

Before purchasing a computer case you should think out where the computer is going to be placed.

  • Is it going to be on your desk or your floor?
  • Is it going to have enough space at its location with the monitor and other peripherals possibly next to it?
  • If it’s in a bedroom will it be quiet enough if left on while you sleep?

Upgrade availability

  • Does the case have enough bays for adding additional hard drives or other drives?
  • Does the case have the availability for slots for additional expansion cards

Memory

Random Access Memory (RAM) is the best known form of Computer Memory. The Read and write (R/W) memory of a computer is called RAM. The User can write information to it and read information from it.With Ram any location can be reached in a fixed ( and short) amount of time after specifying its address.

The RAM is a volatile memory, it means information written to it can be accessed as long as power is on. As soon as the power is off, it can not be accessed. so this mean RAM computer memory essentially empty.RAM holds data and processing instructions temporarily until the CPU needs it.

RAM is considered “random access” because you can access any memory cell directly if you know the row and column that intersect at that cell. RAM is made in electronic chips made of so called semiconductor material, just like processors and many other types of chips. In RAM, transistors make up the individual storage cells which can each “remember” an amount of data, for example, 1 or 4 bits – as long as the PC is switched on. Physically, RAM consists of small electronic chips which are mounted in

Microcomputer

Microcomputer

 an electronic device with a microprocessor as its central processing unit (CPU).

Microcomputer was formerly a commonly used term for personal computers, particularly any of a class of small digital computers whose CPU is contained on a single integrated semiconductor chip. Thus, a microcomputer uses a single microprocessor for its CPU, which performs all logic and arithmetic operations. The system also contains a number of associated semiconductor chips that serve as the main memory for storing program instructions and data and as interfaces for exchanging data of this sort with peripheral equipment—namely, input/output devices (e.g., keyboard, video display, and printer) and auxiliary storage units. Smaller microcomputers first marketed in the 1970s contain a single chip on which all CPU, memory, and interface circuits are integrated.

As large-scale integration and then very-large-scale integration have progressively increased the number of transistors that can be placed on one semiconductor chip, so the processing capacity of microcomputers using such single chips has grown commensurately. During the 1980s microcomputers came to be used widely in other applications besides electronic game systems and other relatively simple computer-based recreations. Increasingly powerful microcomputers began to be used in personal computer systems

Computer application buying tip

Purchasing a software application or program can be a big consideration, especially when purchasing advanced and usually expensive programs such as Microsoft Office or Adobe Photoshop. When considering purchasing these programs it is important that you or your staff be familiar with the program and are sure it’s going to be capable of what you need it to do.

On this page we’ve listed different considerations to think about before buying a computer software application.

 Competition

Before buying any application make sure there is not a competing program that may be cheaper or even free. If available and something that’s capable of doing what you want it to do this could save you hundreds of dollars.

A good example of such a program is OpenOffice and Corel WordPerfect that would be a competitor to Microsoft Word. Both programs are an excellent choice for a word processor but can be a considerable price difference. In the case of OpenOffice, it’s 100% free.

Documentation

Make sure proper documentation is included. Many programs today will include on-line documentation that is more than sufficient. However, it is also useful to obtain a manual or user guide for the software program or application.

Licenses

If you are
