Quick Guide to Buying a Computer Processor

The central processing unit (CPU) of your computer does not refer to the entire computer box as many ordinary users mistakenly call it. But it is a small piece of hardware that is also called the processor or microprocessor that reads, converts, and disposes majority of the instructions inside your computer. It is also often referred to as the "brain" or the 'think tank" of your computer. That is why buying a CPU should be well advised and thought of to maximize computer use.

Here are the basic features that should guide you when buying a CPU:

Speed

Quick Guide to Buying a Computer Processor

Not too long ago, the speed of processors was measured in megahertz (MHz) but at the rate that technology is progressing, a processor running in MHz is a thing of the past. Buying a CPU nowadays recognize a standard clock speed that is measured in gigahertz (GHz) which is equivalent to 1000MHz per 1GHz. The higher the clock speed is, the faster your CPU can process information. The latest processors have speeds ranging from 2GHz to over 3GHz.

Other speed indicators to consider when buying a CPU are the:

Bus speed - which is measured in MHz that determines the rate at which the processor and the memory controller communicates. A 200MHz bus speed is most common nowadays.

Cache - if the CPU is the brain, the cache may be likened to the left temporal lobe of our brain that facilitates language and verbal memory and gives assistance in organizing and sequencing events. The cache captures recent data and assists in speeding up processing. A bigger cache in the CPU is definitely an advantage.

Different types of CPU

When buying a CPU look for the best known brands which are Intel and AMD. The Intel brand is relatively more expensive but consistently delivers in quality. AMD Athlon processors are cheaper with very good quality as well. Whichever brand you choose, it is important to ensure that your motherboard supports the type of processor because the connectors and slots vary per model.

Buying a CPU for your new computer or for upgrading your existing unit boils down to budgetary considerations and your needs. Do not settle however for the hardware with less than two processors in one chip. Always look for a dual core or multicores. Intel and AMD both offer budget, mid-range and high-end priced CPU's that carry the current features mentioned above.

Budget price range

Intel Pentium E5300 is currently priced at .99 and has a dual core processor with a clock speed of 2.6GHz, 2MB Level 2 (L2) cache and an 800MHz bus speed.

AMD Athlon II X2 costs .99 with dual core processor, 3GHz clock speed and 2MB L2 cache

These models that are reasonably priced perform quite well for your basic computer needs and allow you to multitask.

Mid-range price

Intel Core2 Duo costs 9.50 with dual processors, 3GHz clock speed, 6MB of L2 cache and 1333MHz of bus speed.

AMD Phenom II costs 4.99, has multicores (quadcore), with a clock speed of 3.2GHz and a L2 cache of 4 x 512 kb.

This will already support your gaming and multi-media applications when considering budget constraints.

High-end price range

Intel Core i7 costs 9.99 has four processors in 1 chip with each processor running at clock speeds of 2.8GHz (2.8GHz x 4), 8MB cache, and a bus speed of 4.8 GT/s

AMD Phenom II x 4 costs 9.95 with four processors have a clock speed of 3.2GHz and an 8MB cache.

There are higher models like the Intel Extreme that costs close to a thousand dollars. However, it may not be necessary to splurge on these models when buying a CPU regardless of whether you can afford them because the mid-range models or those that are two to three levels down from the premium models have superior features already that support the latest computer applications.

Call of Duty Black Ops Zombies Guide - How to Win Easily

In Call of Duty: Black Ops, the Zombies mini-game is just as popular as ever. In this Black Ops Zombies Guide, I will be revealing some of the best tactics you can use to get to the highest possible levels in Zombies.

The first thing you should know is to know the difference between Zombies and other players. Zombies are extremely hard to kill unless you shoot them in the head; it is very hard to kill a Zombie by shooting it in the torso, and shooting it in the arms is a waste of ammo.

As a result, if you want to kill Zombies, you will need to start aiming for the head. They move very slowly so this is not nearly as hard to do as when playing against players. You also get more money (points) for headshots, so try to get as many as you can. This is one of the basics of any Black Ops Zombies guide.

Call of Duty Black Ops Zombies Guide - How to Win Easily

Another great tactic is to leave one Zombie alive while regrouping. The next level does not start until you kill the final Zombie, so you can leave a few crawling around until you buy more ammo, guns, and meet up with your team. This strategy is absolutely necessary if you want to make it to the next level, as without it you will not be able to buy guns and ammo in between rounds. If you rush in between rounds, your team will become disorganized and out of supplies.

Thirdly, by level 7 you need to start trying to get a ray gun. You can get a ray gun inside the mystery chest, which can appear at any of the locations marked on the map with the "?" and the green light. Be sure to check all the locations as it can only spawn at one location.

Each round, the Zombies get harder and harder, so if you want to advance far past level 12, you will need everyone on your team to have Ray Guns. Note that you cannot get two Ray Guns; after you get your first one, spend your money on the power-ups like Root Beer (increases reload speed).

The only necessary thing though in this Black Ops Zombies guide is try to make sure everyone gets a Ray Gun. The power-ups are nice additions but not necessary to make it to the advanced levels.

Finally, make sure you kite the zombies around rather than fighting them head on. That is probably the most important strategy in this Black Ops Zombies Guide. Kiting refers to constantly running away from enemies, turning around and shooting a few, then continuing to run.

You are able to run a lot faster than the Zombies, so if you keep running throughout the level, they will eventually amass into a big ball that you can easily kill without having to worry about getting jumped from behind. This strategy alone can take you to the top levels.

Classification of Computers

Computers are available in different shapes, sizes and weights, due to these different shapes and sizes they perform different sorts of jobs from one another.

They can also be classified in different ways. All the computers are designed by the qualified computer architectures that design these machines as their requirements.

A computer that is used in a home differs in size and shape from the computer being used in a hospital. Computers act as a server in large buildings, while the computer also differs in size and shape performing its job as a weather forecaster.

Classification of Computers

A student carrying a laptop with him to his college is different in shape and size from all the computers mentioned above.

Here we are going to introduce different classifications of computers one by one. We will discuss what are in classifications and what job they perform.

Super computer

The biggest in size, the most expensive in price than any other is classified and known as super computer. It can process trillions of instructions in seconds. This computer is not used as a PC in a home neither by a student in a college.

Governments specially use this type of computer for their different calculations and heavy jobs. Different industries also use this huge computer for designing their products.

In most of the Hollywood's movies it is used for animation purposes. This kind of computer is also helpful for forecasting weather reports worldwide.

Mainframes

Another giant in computers after the super computer is Mainframe, which can also process millions of instruction per second and capable of accessing billions of data.

This computer is commonly used in big hospitals, air line reservations companies, and many other huge companies prefer mainframe because of its capability of retrieving data on a huge basis.

This is normally to expensive and out of reach from a salary-based person who wants a computer for his home.

This kind of computer can cost up to thousands of dollars.

Minicomputer

This computer is next in he line but less offers less than mainframe in work and performance. These are the computers, which are mostly preferred by the small type of business personals, colleges, etc.

Personal computers

Almost all the computer users are familiar with the personal computers. They normally know what the personal computer is and what are its functions.

This is the computer mostly preferred by the home users. These computers are lesser in cost than the computers given above and also, small in size; they are also called PCs in short for Personal computers.

This computer is small in size and you can easily arrange it to fit in your single bedroom with its all accommodation. Today this is thought to be the most popular computer in all.

Notebook computers

Having a small size and low weight the notebook is easy to carry to anywhere. A student can take it with him/her to his/her school in his/her bag with his/her book.

This is easy to carry around and preferred by students and business people to meet their assignments and other necessary tasks.

The approach of this computer is also the same as the Personal computer. It can store the same amount of data and having a memory of the same size as that of a personal computer. One can say that it is the replacement of personal desktop computer.
