The following report outlines the hardware and software specifications for a prospective computer system designed to give any small business the ability to automate their daily activities. Two key factors are always kept in mind, efficiency at an affordable cost. Even though more powerful specifications can be given this would increase the overall cost of the system. Another thought that was taken into consideration is the ability of the computer system to be upgraded so that the system can give the company at least five years service. The report is organized into sections. The first gives the hardware specifications with a brief description. A breakdown of the software specifications is given next followed by operating systems and typical office application software alternatives.
2.0 COMPUTER HARDWARE SPECIFICATIONS
3.1 Processor:Intel Core i3 duo-core processor @3.3GHz, 3MB full speed L2 cache. This processor is fast enough (3.3 GHz means 3,300,000,000 instructions executed per second) and allows programs that are designed to use two processor cores to take advantage of its duo core design. 3 MB full speed L2 Cache is an added bonus because it allows the processor to operate more efficiently by immediately accessing data and instructions that are needed frequently. This memory is integrated into the CPU chip and is faster than RAM and operates at the same speed (full speed) of the processor. 3.2 Main Memory:8GB DDR3-1333MHz SDRAM
8 Gigabytes is more than sufficient storage space for the Operating System, background programs and applications that are currently used by the processor. DDR3-1333 MHz is the speed at which RAM operates, which is currently the fastest on the market. This is recommended to allow multiple programs to run at the same time without system performance degradation. 3.3 Secondary Storage:
(i) 500GB - 7200RPM SATA II hard disc drive
A 500 Gigabytes hard drive can store approximately 100,000 songs in MP3 format or 100,000 pictures in JPEG format or 1,000,000 documents which is a substantial amount of permanent storage space for office applications and data. 7200 Revolutions Per Minute (RPM) determines the access time (time taken to get data from the hard drive to RAM) which is the market standard. SATA II describes how the hard drive is attached to the motherboard which is the fastest connection on the market. (ii) 20X DVD±RW/CD-RW Dual Layer drive
For safety consideration, that is, the backing up of all essential office data, this DVD and CD burner allows data to be stored on 4.7 GB discs or 700 MB discs which can be stored off site in the case of fire or natural disasters. 20X is the rate at which data can be stored to the discs which is the market standard (20X is 20 times the burning speed of the first DVD/CD combo drive). 3.4 Motherboard:ASUS P7H57D-V EVO motherboard
A motherboard is mainly chosen based on the processor and this motherboard supports the Intel core i3 chip. ASUS is a known brand for its reliability and robustness. Other factors to take into consideration are the integrated audio and video capabilities, integrated LAN interface, expansion slots and other ports. The following specifications are the capabilities of this motherboard. 3.5.1 4 x DIMM, Max. 16 GB, DDR3 2133(O.C.)/1600/1333/1066 Memory This specifies thetotal capacity of RAM the motherboard can accommodate and the number and capacity of physical sticks of RAM. For this system two 4GB stickswould be used which means if the system needs upgrading it can take an additional two 4GB sticks of RAM. 3.5.2 VGA Maximumshared memory of 1748 MB
Shared memory means the amount of RAM that will be used by the integrated Video Graphics Accelerator (VGA) for the sole purpose of video display. With 8GB, which is 8,000 MB, is more than acceptable because typical office...
