This document provides information about basic computer components and types of computers. It discusses the basic competencies required for computer operations as well as common and core competencies. It then defines what a computer is, its main parts including hardware and software, and types of computers such as laptops, desktops, tablets, and more. The rest of the document describes the basic components of a desktop computer in detail, including the monitor, keyboard, mouse, motherboard, RAM, power supply, CPU, hard disk drive, and optical drive. Memory types such as SIMMs, SDRAM, RDRAM, DDR, DDR2, DDR3, and DDR4 are also explained.

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.
