1.2 Explain computer system

an electronic network that consists of software and hardware that perform a specific task (receive input, process the input, keep the commandments, and provides output in the form of information). Moreover, it can also be interpreted as elements related to running an activity using a computer.

1.3 Identify NAME, goals, and characteristics of cases and power supplies

1.3.1 Describe the case

Computer cases are referred to in several ways:

* Computer chassis

* Cabinet

* Tower

* Box

* Housing

In addition to providing protection and support, it also provides an environment that is designed to keep the internal components cool

There are many factors to consider when choosing a case:

* Size motherboard

* The number of external or internal drive locations called bays

* Available space

* See Figure 2 for a list of features.

1.4 Identify the names, purposes, and characteristics of internal components

1.4.1 Identify the names, purposes and characteristics of motherboards

Motherboard main printed circuit board and contains the buses, or electrical pathways, found in computers. These buses allow data to travel between the various components that comprise the computer. Figure 1 shows the various motherboard. The motherboard is also known as the system board, backplane or motherboard.

Motherboard accommodate the central processing unit (CPU), RAM, expansion slots, heat sink / fan assembly, BIOS chip, chip set, and the interconnect wires embedded motherboard components. Sockets, internal and external connectors, and ports are also placed on the motherboard.

1.4.2 Identify the names, purposes, and characteristics of CPUs

The central processing unit (CPU) is considered as the brain of the computer. sometimes called processor. Most calculations take place in the CPU.

1.4.4 Identify the names, purposes, and characteristics of ROM and RAM


Read-only memory (ROM) ROM chips contain instructions that can be directly accessed by the CPU.


Random access memory (RAM) is temporary storage for data and programs that are being accessed by the CPU.

Memory Modules

Early computers had RAM installed on the motherboard as individual chips.

Memory speed has a direct impact on the amount of data the processor can process due to faster memory improves processor performance. Along with the increase in processor speed, memory speed should also increase. For example, single-channel memory is capable of transferring data at 64 bits. Dual-channel memory increases speed by using both channels of memory, making data transfer rate of 128 bits.

Double Data Rate (DDR) SDRAM technology doubles the maximum bandwidth.


SRAM is used as cache memory for storing data used most often.


Error Checking

Memory errors occur when the data is not stored properly in a RAM chip. The computer uses a different method to detect and correct data errors in memory.

1.4.5 Identify the names, purposes and characteristics of adapter cards

Card adapters enhance the functionality of your computer by adding the handler for a particular device or by replacing the damaged port. show some kind of adapter cards adapter.Kartu used to extend and customize the capabilities of the computer:Network Interface Card (NIC)                           Wireless NIC

1.4.6 Identify the names, purposes and characteristics of storage drives

Storage drive, read or write information to a magnetic or optical storage media. Drive can be used to store data permanently or to retrieve information from the disk media. Here are some common types of storage drives:

Floppy drive                                               Hard drive

Optical Drive                                              Flash drive

Floppy Drive

A floppy drive or floppy disk drive, is a storage device that uses removable 3.5-inch floppy disk. This magnetic disks can store 720 KB or 1.44 MB of data.

Hard Drive

A hard drive, or hard disk drive, is a magnetic storage device installed in the computer.

Traditional magnetic hard drives. Hard drive has a magnetic motor that is designed to spin magnetic platters and the drive heads.

Optical Hard

Optical drive is a storage device that uses a laser to read data on optical media. There are three types of optical drives:

Compact Disc (CD)

Digital Versatile Disc (DVD)

Blu-ray Disc (BD)

CD, DVD and BD media can be pre-recorded (read-only), recordable (write once), or re-recordable (read and write multiple times). CD has a storage capacity of about 700 MB. DVD has a storage capacity of 4.3 GB of data on a single-layer disc, and about 8.5 GB on a dual-layer disc. BDS has a storage capacity of 25 GB on a single-layer disc and 50 GB on a dual-layer disc.

There are several types of optical media:

CD-ROM                    CD-R

CD-RW                      DVD-ROM

DVD-RAM                   DVD + /-R

DVD + /-RW                              BD-ROM BD

BD-R                                         BD-RE BD

External Flash Drive

An external flash drive, also known as a thumb drive, is a removable storage device connected to the USB port.

Interface Hard

Hard drives and optical drives are manufactured with different interfaces used to connect the drive to the computer.

IDE Integrated Drive Electronics, also called Advanced Technology Attachment (ATA) is an interface controller that connects the hard start the computer and hard disk drives. An IDE interface uses a 40-pin connector.

PATA Parallel ATA refers to the parallel version of ATA drive interface controller.

SATA Serial ATA refers to the serial version of the ATA drive interface controller.

External Serial ATA eSATA provides hot-swappable, external interface for SATA drives. ESATA interface to connect an external SATA drive using a 7-pin connector.

RAID provides a way to store the data on your hard disk for redundancy. For the operating system, RAID appear as one logical disk. See Figure 2 for a comparison of different RAID levels. The following terms describe how RAID stores data on disk is different:

* Parity is a method used to detect data errors.

* Striping A method for writing data across multiple drives.

* Mirroring A method of storing duplicate data to both drives.

1.4.7 Identify the names, purposes, and characteristics of internal cables

Drive requires both power cables and data cables. A power supply will have a SATA power connector for SATA, Molex power connector for PATA drives, and Berg 4-pin connector for the floppy drive. Buttons and LED lights on the front of the case is connected to the motherboard with front panel cables.

Data cable to connect the drive to the drive controller, which is located on the adapter card or on the motherboard. Here are some common types of data cable:

1.8 Explain system resources and their purposes

System resources used for the purpose of communication between the CPU and other components in the computer. There are three common system resources:

Interrupt Request (IRQ)                             Input / Output (I / O) Port Address

Direct Memory Access (DMA)     interrupt Request

Input / output (I / O) port addresses used to communicate between devices and software. I / O port address is used to send and receive data to the components.
