1. Intel Celeron
2. Intel Pentium
3. Intel Dual Core
4. Intel Core 2 Duo
5. Intel Core I3, I5, I7

There are three types of ram in the market.
1. SD RAM
2. DDR RAM
3. RD RAM
SDRAM (Synchronous Dynamic Random Access Memory)
SDRAM is a memory which is synchronized interface. It wait for a clock signal before responding to control inputs and then synchronized with the computer system bus. It has 168 pin, 3.3 volt, 66 MHz speed and 2 notchs points. This RAM is very slow performance that is why it is replaced by the fastest performance RAM.
DDR RAM (Double Data Rate Synchronous Dynamic Random Access Memory)
Basically DDR RAM are double the rate of data transfer then the S DRAM. Three types of DDR RAM are found in the market
1. DDR1
2. DDR2
3. DDR3
DDR1

RAM (Random Access Memory) is a memory where the data stores temporary. It is using by the system to sore the data for processing by central processing unit. The data which has stored in hard disk drive can not access randomly because of blocked data. The processor random access the selected data with the help of operating system (windows). When the computer shout down the random access data of RAM is automatically lost itself, so this is not permanently storage memory, it is only temporary storage memory.

Personal Computers are designed for individual users. Personal Computers are as follows-
- Desktop Computer
- Notebook Computer
- Net book Computer
- Tablet Computer
- PDA Computer
Desktop computer
Desktop Computer is a personal computer which are formed for regular use at a single location. Desktop computer has separate monitor, keyboard and mouse. The early desktop computer were designed to lay flat on the desk but the modern computer has tower stand.
Notebook Computer
Notebook Computer is a personal computer which are smaller size than briefcase. We can easily transport and conveniently used in temporary spaces such as class room, libraries, office, meeting etc. Notebook computer is generally called as Laptop Computer. Notebook included keyboard, mouse pad, monitor (display screen), speakers in a single unit.
Net book Computer
Net book Computer is a personal computer which is small size and low power of notebook computer. It has less processing power than the notebook computers but it is suitable for web browsing and connecting wirelessly to the internet.
Tablet Computer
Tablet Computer is a personal Computer which is a kind of mobile computer having a touchscreen or pen-enabled interface. It runs by adapted version of a desktop operating system. It is smaller than notebook computer but larger than smart phone.
PDA Computer
PDA (personal digital assistant) Computer is a personal computer which is a mobile device functioning as a personal information manager. We can use this for storing telephone numbers, email address, make calculations, keep the digital calendar, play games, excess the internet and so on.

On the basis of physical structure and purpose of their uses computers are classified as follow
- Super Computer
- Mainframe Computer
- Micro Computer
- Mini Computer
Supercomputer
Supercomputer is a computer which performs the highest operational rate for computers. The supercomputers are typically used for scientific and engineering application where they must handle huge amount of database and great amount of computations.
Mainframe Computer
Mainframe computer is that computer which is used in huge business where the data is processing in huge amount and processed the data so many times where may require too much CPU cycles (some of the computers may flunk). Mainframe computers are very similar to the supercomputers but the supercomputer calculates algorithms which has so many integration and differentiation and lots of calculation steps, where the mainframes are calculate simple calculations like addition and subtractions.
Micro Computer
Microcomputer is a computer which has microprocessor as a central processing unit (CPU). Microcomputers has cpu, memory, and input and output device. This computers are physically very small than mainframe computer and supercomputers. Micro computers are also called personal computer (PC) which are designed for personal or individual use.
Mini Computer
Minicomputers are those computers which are mid size between microcomputers and mainframe computers. This computers are using in large enterprise where 4 to 400 person can use this computer at a time. In recently mini computer evolved mid range of server computer eg. AS/400e.

On the operational principle computers are classified into two class-
- Analog Computer
- Digital Computer
- Hybrid Computer
Analog Computer
An analog Computer is a form of computer which uses the continuously changeable aspects of physical phenomena such as electrical, mechanical or hydraulic quantities to model problem being solved. The Mechanical Analog computer were very important in gun fire control in second world war.
Digital Computer
Digital Computers are that computer which has the capable of solving problems by processing information in discrete form. It operates on data including magnitudes letters and symbols that are expressed in binary form. Digital computers can perform such tasks as to control industrial processes and regulate the operations of machines (analyze and recognize vast amount of business data) and simulate the behavior of dynamic systems. (eg. global weather patterns and chemical reactions etc.)
Hybrid Computer
Hybrid computers are that computer which has both analog and digital computer's functions and features. Analog computers provide efficient processing of different equations and digital computer provide logical operations associated with system.Creating this type of integrated computer, the benefits of both analog and digital computer are readily available. Hybrid computer is extremely fast when it comes to managing equations, even those calculations are extremely complicated.
