COMPUTER SYSTEMS SERVICING IX CORRECT SPECIFICATIONS  SPECIFICATION The term "specs" comes from the word specification. Specifications are requirements of computers for technical details of components and functionality of the computer. These include information concerning speed, power, memory, graphics, and 1. RANDOM ACCESS MEMORY The RAM is measured in Gigabytes (GB). The amount of RAM a computer requires depends on the software it needs to run efficiently.  THINGS TO LOOK FOR: 1. Speed Measured in MHz. Timing (Column Access Strobe) a control signal used to access data stored in rows and columns.  Column Access Strobe CAS latency: 1st digit refers to the number of clock cycles it takes for the memory module to respond with data after receiving a read  Column Access Strobe Row to Column delay: the 2 digit refers to nd the number of clock cycles it takes to activate the correct row.  Column Access Strobe Row Pre-charge Time: The 3 digit refers to the rd number of clock cycles it takes to close an active row and prepare to open a new one in the memory  Example of Technical Specification DDR3 Speed grade : 1333MHz Unbuffered DIMM : 240-pin CAS latency : 9-9-9 2. PROCESSOR The Central Processing Unit (CPU) or processor is an integrated electronic circuit which carries out the calculations running a computer.  CORES The functionality of multi- core processors have become more popular, and software has developed to use multi-core technology. There are some options to choose, from dual-  CACHE a form of very fast memory channels that is inserted into the processor chip and used to store instructions to slow down as little as possible between tasks. Cache is measured in Megabytes (MB).  SOCKET COMPATABILITY Enables the interface between the motherboard and its CPU. After you have already purchased a motherboard, confirm the processor mounted if it is compatible with its socket.  Integrated Graphics Processing Units (GPUs) Designed to perform graphics-related calculations. If the processor does not have an integrated GPU, the computer can still display the graphics if there is a separate graphics card or if  FREQUENCY The CPU frequency is measured in hertz (Hz). It is the speed the CPU that runs while working. If the CPU architecture operates at a lower frequency, it will potentially work better than  FRONT SIDE BUS (FSB) is a communication interface that acts as the major link between the CPU and system memory with the other parts of the chipset and motherboard. FSB speed is measured in hertz (Hz) and is 3. VIDEO CARD Also known as graphics card, a video card is a piece of hardware inside the computer that processes images and videos. The more efficient the GPU (Graphic Processing Unit), the faster information will be shown and better overall visual experience will be displayed. 3. DATA STORAGE (HDD/SSD) Refers to the secondary memory of the computer which is a non- volatile memory that can store large amount of data. Both are measured in GB/TB.
