Mother BoardRAM SlotsAmemory slot,memory socket, orRAM slotis what allows computer memory (RAM) to be inserted into the computer18CompTIA A+ Exam : 220-801

Mother Board- RAM SlotsRIMM SlotsRIMMis not an acronym and is a trademark ofRambusincorporated for the Direct Rambus or DRAM (RDRAM) modules. RIMM is computer memory that resembles DIMMs; however, it is 184-pin and is available with built in ECC (Error Checking & Correction) support and Non-ECC at speeds up to 800MHz. RIMM modules are commonly used on theIntelPentium 4motherboards.19CompTIA A+ Exam : 220-801

Mother Board- RAM SlotsDIMM SlotsShort forDual In-line Memory Module,DIMMis a circuit board that holds memory chips. DIMMs have a64-bitpath because of the Pentium Processor requirements. Because of the new bit path, DIMMs can be installed one at a time, unlike SIMMs on a Pentium that would require two to be added. Below is an example image of a 512MB DIMM memory stick20CompTIA A+ Exam : 220-801

Mother Board- RAM SlotsSODIMM SlotsSO-DIMMis short forSmall Outline DIMMand is available as a 72-pin and 144-pin configuration. SO-DIMMs are commonly utilized inlaptop computers21CompTIA A+ Exam : 220-801

Mother Board- RAM SlotsSIMM SlotsShort forSingle In-line Memory Module, SIMMis a memory module developed by Wang laboratories in1983. The SIMM circuitboard that holds six to nine memory chips per board, the ninth chip usually an error checking chip (parity or non parity). The SIMM was used with computers using a 486, earlyIntelPentium, and compatible processors. However, because the Pentium is 64-bit and a SIMM is only 32-bits wide, they must be installed two at a time when used with any 64-bit processor.22CompTIA A+ Exam : 220-801

Mother Board- SlotsPATA SlotsThe first ATA interface is now commonly referred to asPATA, which is short forParallel AT Attachmentafter the introduction ofSATA. AT Attachment,ATAwas first approved May 12,1994, under theANSIdocument number X3.221-1994 and is an interface used to connect such devices ashard drives,CD-ROM drives, and other disk drives.23CompTIA A+ Exam : 220-801

Mother Board- SlotsPATA Slots Cont..IDE - Integrated Drive ElectronicsorIBM Disc Electronics,IDEis more commonly known asATAorParallel ATA(PATA) and is a standard interface for IBM compatible hard drives.EIDE - Alternatively referred to as aTA-2,Fast ATAandFast IDE,EIDEis short forEnhanced IDEand is the next generation of IDE interface that was developed byWestern Digitaland an interface commonly used on IBM compatible computers. EIDE supports data rates from 4 and 16.6MBps. In addition to being faster than IDE drives, EIDE supports drives up to 8.4GB.24CompTIA A+ Exam : 220-801

EIDEMother Board- SlotseSATA Slots In addition to being an internal solution SATA also supports external drives throughExternal SATAmore commonly known aseSATA. eSATA offers many more advantages when compared to other solutions. For example, it ishot-swappable, supports faster transfer speeds and no bottleneck issues when compared with other popular external solutions such asUSBand Firewire, and supports disk drive technologies such asS.M.A.R.T..However, eSATA does have some disadvantages such as not distributing power through the cable like USB, which means drives will require an external power source and it only supports a maximum cable lengths of up to 2 m.25CompTIA A+ Exam : 220-801

Mother BoardCPU SocketsACPU socketor CPU slot is a mechanical component(s) that provides mechanical and electrical connections between amicroprocessorand a printed circuit board(PCB). This allows the CPU to be replaced without soldering.26CompTIA A+ Exam : 220-801
