- 31. • Software is like a cord made up of separate threads. It routinely uses one thread at a time, and others use many threads called multithread.
- 33. It is a hardware device that allows information to be stored and retrieved on a computer. It is a volatile memory and needs the power to keep the data available. If the machine is switched off, all data contained in RAM is lost.
- 34. . SIMMs come in two different sizes, as shown in the figure below, so both sizes require a different-size socket. Early, pre-Pentium computers use the tinier size (31⁄2 inches long), which has 30 pins and typically holds fewer than 20MB of RAM capacity.
- 36. SDRAM DIMM (Synchronous Dynamic Random- Access Memory Dual In-line Memory Modules) is short for SDRAM, is a type of memory that matches itself with the computer's system clock. Being synchronized allows the RAM to run at higher speeds than previous memory types and asynchronous DRAM and supports up to 133 MHz system bus cycling.
- 38. RDRAM (Rambus Dynamic Random-Access Memory) It was developed by Rambus initially released in 1999. It is a memory technology that offers a 1.6 GB/s of theoretical memory bandwidth and offers better memory access at a little higher cost when compared to SDRAM.
- 40. DDR SDRAM (Double Data Rate SDRAM) It was the first version of this technology and achieved its speed increase by transferring data twice per cycle, i.e., on both the increasing and then the dropping edge of the clock signal.
- 41. DDR2 SDRAM (Double Data Rate 2 SDRAM) Short for double data rate two, It is the 2 nd generation of DDR memory that was released in September 2003. It can operate at higher speeds than DDR, offers higher speed, operates on less power, and generates less heat. Due to architectural variances, DDR2 memory modules are incompatible with predecessor (D.D.R.) slots. It transfers 64 bits of data twice every clock cycle. DDR2-SDRAM memory is not compatible with the current DDR-SDRAM memory slot.
- 43. (Double Data Rate 4 SDRAM) It is a kind of system memory known as SDRAM and was launched in September. It has a bus clock speed that starts from 800 to 1600 MHz and storage capacity from 4 to 128 GB (theoretical maximum size per module) per DIMM.
- 45. is a non-volatile data storage device. Non-volatile memory is a term used to store data regardless if the computer has power. Internal HDD in a drive bay(space provided for HDD drive) connected to the motherboard using an ATA, SCSI, or SATA cable.
- 47. POWER SUPPLY UNIT (PSU) It is a hardware component of a computer that provides the power needed by the computer and its components.
