12 Looking at the System Unit Often most important and expensive part Separate devices inside box perform specialized functions Notebook has same components as desktop Microprocessor chip Often called brain of computer as instructions from software programs and input received are executed here Referred to as Central Processing Unit (CPU) and processes information and instructions at different speeds Hertz (Hz) measures speed of internal computer clock in terms of frequency or number of cycles per second Dual and quad core processors contain two or four processor chips CCI Learning Solutions Inc.
13 The Microprocessor Chip Processor (CPU) MHz or GHz 8088 (XT) 4 to 10 MHz 80286 (286 or AT) 8 to 16 MHz 80386SX/DX (386SX/DX) 16 to 33 MHz 80486 (486) 25 to 100 MHz Pentium 60 to 200 MHz 6x86 120 to 166 MHz Pentium (MMX) 166 to 200 MHz Pentium PRO 150 to 200 MHz Pentium II 200 to 400 MHz Pentium III 500 MHz to 1.2 GHz Pentium 4 or Pentium M1.4 to 3.2+ GHz
Pentium 5 5 GHz to 7 GHz CCI Learning Solutions Inc. 14 Looking at Memory Computers developed using numbering system of 1s and 0s or binary system For computer to store information, must have memory chips installed Memory measured in bits and bytes Bit is smallest unit of data used by computers Group of eight bits make one byte 1 Kilobyte = 1 Megabyte = 1 Gigabyte = 1 Terabyte =
1 Petabyte (PB) 1,024 Bytes 1,048,576 Bytes 1,073,741,824 Bytes 1,099,511,627,776 Bytes = 1,125,899,906,842,624 Bytes All data made up of bytes in combinations calculated by computer Every file used in software program has specific file size Data file size increases or decreases based on contents stored CCI Learning Solutions Inc. 15 Read Only Memory (ROM) BIOS Group of integrated circuits responsible for: Starting computer
Checking RAM Loading operating system Occurs only when computer first turned on or each time you restart (reboot) computer Reads information entered and processes it during time it resides in memory When process complete, clears itself and waits for next entry Does not perform any tasks other than reads information and processes it CCI Learning Solutions Inc. 16 Random Access Memory (RAM) Located in system unit as electronic memory pool where computer holds copies of programs and data Temporarily stores software program currently using and data created in program; may be referred to as system
RAM RAM is volatile Measured in nano seconds (ns) Used in video display cards or to buffer information sent to printer CCI Learning Solutions Inc. 17 Random Access Memory (RAM) Processor (CPU) MHz / GHz Typical RAM 8088 (XT) 4 to 10 640Kb 80286 (286 or AT) 8 to 16 1 to 2Mb 80386SX/DX (386SX/DX) 16 to 33 1 to 8Mb 80486 (486) 25 to 100 4 to 32Mb

ROM BIOS takes control when computer started and loads operating system 2. When operating system gains control, see Windows
splash screen Operating system checks Windows registry, which identifies what hardware and software installed When complete, see Windows desktop 3. Certain amount of RAM used to run basic files As computer performs specific tasks, it uses RAM needed When starting software application or program, asking computer to put copy of program in RAM Close application program when not in use to make RAM available CCI Learning Solutions Inc. 19 Lesson 3: Working with Storage Systems storage systems hard disk drives optical drives
portable or removable storage devices network drives remote storage CCI Learning Solutions Inc. 20 What Are Storage Systems? RAM is temporary so you must save work to storage device Storage device you use depends on amount of storage you need and speed of data retrieval or data transfer rate Hard disk drives used most often to store and retrieve software programs and data Can use other media such as flash drive or optical disc for backup or portability purposes
CCI Learning Solutions Inc. 21 Working with Disk Drives Disk drive performs three functions: Rotates disk at constant speed to access sectors on entire disk surface Moves read/write head across tracks on entire disk surface Reads data from disk and writes data to disk using read/write head Data from RAM written on disk arranged in tracks divided in sectors Process of preparing disk for use is called formatting Places special information on each track that marks location of each sector CCI Learning Solutions Inc.
22 Working with Hard Disk Drives Primary storage area for both data and programs Software programs must be installed on hard drive Hard drive stores and retrieves information at high speeds Data transfer rate (throughput) of hard drive is function of hard drive rotation speed and number of heads per surface The higher the rotation speed and/or number of heads, the less time it takes to find data Range in capacity from 100 MB to 100+ GB Also used in network servers where drives very large to accommodate requirements of whole organization and data storage requirements Data transfer rate quite fast although can be restricted by type of network interface cards and number of users or tasks to be processed
CCI Learning Solutions Inc. 23 Working with Optical Drives Designed to read flat, circular disc, commonly referred to as Compact Disc (CD) or Digital Versatile/Video Disc (DVD) Read by laser device or optical drive that spins disc at speeds from 200 rpm or higher CD-ROM (Compact Disc Read Only Memory) or DVD-ROM drive Similar to player in audio/video entertainment system Information written or burned onto surface and retrieved with laser beam Can only read data New computers come with at least one optical drive
