The Different Types Of Motherboards Computer Science Essay

Published:

The motherboard is the primary circuit board or the main circuit board of a computer system. The motherboard helps to control the flow of data and electricity for all the components in a PC such as CPU, RAM, sound cards, graphic adaptor which are primary devices needed to run the computer are connected to the motherboard. Motherboard also contains slots and ports to attach other components such as storage devices, chipsets, graphics cards, CD's and other various supported system hardware.

I have discussed about few motherboard platforms below:

TYPES OF MOTHERBOARDS

The type of motherboard depends on the dimension and size of it and the layout of the components in it. Also you need to know the CPU model it is designed for, because you cannot place every motherboard in any computer system. It should be specified with the brand name. such as ATX motherboards can be placed in an ATX case only.

ATX was introduced in 1995 and was the first motherboard to only include I/O supported ports, also it was the motherboard which outdated the Baby AT design modifying the layout by rotating the CPU and memory 90 degrees, which allowed full expansions to be plugged and allow proper cooling. It is 7.5 inches wide and 12 inches long. This motherboard supports most modern system ports and slots.

Numerous variations of the ATX were subsequently introduced with both smaller and larger form factors, including the microATX, Mini ATX, FlexATX

BTX Motherboards (Balanced Technology Extended)

Introduced in 2004 by intel, and is the latest PC form factor introduced to the market. It offers all the features of an ATX board but with a modified layout which is designed in a way to improve the cooling and airflow through the whole circuit.

However the intel couldn't reach the level of popularity they targeted because this layout is not compatible with all the computer designs. As a result, intel discontinued producing BTX boards.

Standard size of a BTX board is 12.7 inches by 10.4 inches compare to ATX it is a bit larger and more opening ways to cool out the system.

MEMORY MODULES

RAM (Random Access Memory)

Ram is used for temporary storage of data and instructions. RAM is much faster compare to the storage devices though it is a short term memory device. It is Volatile memory; the data stored in the memory will be erased when the system power is turned off. The main use of the RAM is to hold the data, programs and applications which are being currently used the user in operating system. There are 2 types of RAM memory, DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory). The difference between DRAM and SRAM is DRAM needs electrical current to be constantly refreshed, but in case of SRAM it does not need electrical current to be refreshed periodically and SRAM is more expensive but faster and more reliable than DRAM.

Different types of RAMs

DDR SDRAM (Double Data Rate Synchronous Random Access Memory)

It has the same design as SDRAM makes faster transfer by more strict control of the timing of the electrical data and clock signal. SDRAM uses DataStrobe which contains more advanced synchronization electronics which locate data more accurate.

DDR2 SDRAM (Double Data Rate-2 Synchronous Random Access Memory)

It is alike DDR SDRAM, but DDR 2 allows higher bus speed and requires lower power. The data is transferred in 64bits at a time.

DDR3 SDRAM (Double Data Rate-3 Synchronous Random Access Memory)

This interface technology is used for higher bandwidth storage of the working data. The primary benefit of DDR3 is the ability to transfer at twice the data rate of DDR2.

STORAGE DEVICES

Storage device is a hardware device designed to store data. There are two types of storage devices used in computers, primary and secondary storage device.

Primary Storage Device

Primary storage is also referred as main memory, or internal memory. It holds memory for a short period of time while the computer is on. For example RAM and Cache both are primary memory components. They are volatile memory type but faster in process than any other storage device.

Secondary Storage device

Secondary storage is also known as external memory. It is a storage device which stores information and hold till it is deleted. Example Hard Disk Drive, it is used to store data for long period.

Offline storage devices are also counted as secondary storage devices. As the data can be stored for a longer period.

Below are some examples of secondary Storage devices

Hard Disk Drive: Hard Disk Drives are secondary storage devices which are placed inside the computer system. It is a physical drive capable of holding and retrieving information. Data is encoded is encoded magnetically.

Portable Hard Disk Drive: It is a type of Hard Disk Drive which is connected externally to the computer. It is a portable drive which can be carried anywhere and can be connected to any PC. The drive will hold da data unless they are deleted. These cables are connected to the PC through USB cables. The power and data are transferred to the device through the cable. It is more easy and safe way of storing data, the data stored hard drive can be placed any where safe and can be carried with the user.

USB Flash Drives: It is a flash memory data storage device with a USB 1.1 or 2.0 interfaces. It is also known as a pen drive as it is portable and small in size. Though it is physically small in size they are faster, and can have a larger capacity. There are 256GB pen drives now in market, it has improved with the technology. Also the cost of it is lower compare to its usage level.

Compact Disc (CD): It is an optical device used to store digital data. They were introduced in 1982 to store sound recordings exclusively. But lately it also allowed storing other types of digital data. Also the technology expanded CD-R (write once audio and data storage) with CD-RW (rewritable CDs). Standard CD's had a diameter of 120mm and can hold up to 700 MB of data.

Digital Versatile Disc (DVD): Also known as Digital Vedio Disc. It was introduced in 1995. It is of the same dimension of a Compact Disk but are capable of storing more than six times as much data. These disks are readable only from a DVD-ROM (Read Only Memory) or a later version of a ROM. DVD-R / DVD+R (recordable) can only record the data once but the DVD-RW / DVD-RAM can rewrite data multiple times. The vedio data written on DVD are more quality compare to CD, as it contains a large capacity of space and can use the space to write quality data.

Blu-Ray Disc: Its main uses are storing high-definition video and plastation3 video games and other data. These discs consists a storing capacity of 25 GB per single layered and 50 GB for a double layered disc. These are the latest technological discs available in the market. These discs have the same dimension as of a standard DVD and CD. But these discs are readable only from a special ROM which contains Blue laser. It is one of the latest technologies introduced in this century.

NICs and Wireless Network Devices

NIC (Network Interface Card)

IC is a hardware interface between a computer and a network cable that connects PC to the rest of the network. They translate the data sent by the computers to a network cable supportive way and controls the data while it is sent to other PCs in the network. These cards are connected through wires (Ethernet) or wireless (Wi-Fi) standards. In new computers mostly NICs are installed internally by manufacturers. These NICs features a speed of suck as 11 Mbps, 54 Mbps or 100 Mbps.

There are different types of NIC arrangements or configurations

Jumper configurable NICs - have physical jumpers (small devices that control computer hardware without the need for software). These NICs are suitable for older equipments.

Software Configurable NICs - These NICs are configured manually using a software program.

Plug-and-Play Configurable NICs - auto-configure upon installation during the system boot-up sequence, doesn't have to be manually configured. This technology is used in all the modern computers.

Wireless Network Device

Wireless network refers to any type of computer networking without using cables or wires (wireless). These networks are generally operated with some type of remote information transmission system that uses electromagnetic waves, such as radio waves,

There are different types of devices used for wireless networking. Some are discussed below:

Bluetooth - is an open wireless technology used to transfer or exchange data from a short distance. It was introduced by a telecoms vendor Ericson in 1994. It transfers data using short length radio waves networking the devices. Mainly it was fixed in mobile phones to overcome problems of synchronizing data, designed for low power consumption with a short range of distance. But now a days you can be able to see Bluetooth in almost everything as a mean of ease of transferring data.

WiMAX (Worldwide Interoperability for Microwave Access) - It is the 4th generation of wireless technology designed to enable high-speed mobile Internet access to the widest selection of devices including notebook PCs, handsets, smart phones, and gaming devices, cameras, music players etc. It allows low cost open networks enabling efficient networks of data, video and audio.

Netgear WG302 Access Point - It is more secure to use as it has WEP and WPA security systems. But it is expensive in cost and also the auto cells won't work while using the device as a repeater or bridge.

Web Browsers - browsers like Internet explorer or Mozilla Firefox are required to access and view web pages via internet.

Monitors

A monitor or visual display is an electronic visual display for computers. It plays a major role of a computer system as it is the output device which displays the income of a computer.

Numbers of good monitors are important in a laboratory. Monitors differ with size, quality, and other features.

Cathode Ray Tube Monitors (CRT)

A CRT monitor is the oldest or traditionally used monitors.

It works by moving an electron beam back and forth across the back of the screen.

Physically it's large in size more like a box (bulky) - takes space.

Consumes lot of electricity

Cost is cheaper as it is rarely used now

Liquid Crystal Monitors (LCD)

Flat display made up of any number of color or monochrome pixels arrayed in front of a light source or reflector.

Slim in size - light in weight and can be placed in just a small space of a table or can be hanged on wall (easy to use)

A very small amount of electricity is consumed.

Affordable cost with consumer friendly characteristics.

In my opinion LCD monitors will be suitable for the computer lab comparing the features pointed above. LCD monitor is all the way better than CRT monitors. And to a modern computer lab LCD is the best suitable monitors.
