ARCHITECTURE OF COMPUTER


MAJOR PARTS OF COMPUTER

CENTRAL PROCESSING UNIT (CPU)

INPUT DEVICES

OUTPUT DEVICES

MEMORY UNIT

VARIOUS INPUT/OUTPUT DEVICES


Input Devices Keyboard. (Wired / Wireless/Multimedia) Mouse.(Wired/Wireless/Optical/ Bluetooth/2 Button/3 Button) Stylus. (Track Pad, Touch Pad, Pen) Touch Input. Motion Sensors.

Output Devices Monitor. (VGA, CRT, TFT, LCD, LED) Printer. (Dot-Matrix, Inkjet, Laser Printer) Plotter. 3D Printer. LCD Projectors.

MEMORY & TYPES


Based on Its Location Internal (RAM/ROM) & External Memory (Ext HardDisk / Pen

Drive / Thumb Drive, CD/DVD/BRD, SD Cards ) Based on the Materials

Semiconductor (RAM,ROM,SD Cards / Magnetic (Internal, External Hard disk / Optical Memory CD,DVD,BRD)

Based on the Functionality Volatile Memory(RAM) / Non –Volatile Memory (ROM &

Others)

MEMORY Calculations


Binary Digit – 0 or 1 (bit) 4 bits = 1 word 8 bits = 2 words = 1 Byte 1024 Bytes = 1 kilo Byte (kB) 1024 kilo Byte = 1 mega Byte (MB) 1024 mega Byte = 1 giga Byte (GB) 1024 giga Byte = 1 Tera Byte (TB)

Analog VS Digital Computer


Normal (Human & Animal)Voice is Analog Signal. Vibrations are Analog Signal. Needed devices to convert analog signal to digital signal. Computer can operate and store only in digital data. But it can convert analog to digital and vice versa. Simple example for a digital data is normal switch which

can be operated in any one of the two states(ON / OFF) There are some hybrid computers which can operate in

Analog as well as digital data like Medical Scanners etc.,

Computer Languages

PUZZLE


Assume there are 10 equal size boxes and I am providing you 1000 Re.1 coin.

You need to put those 1000 coins in the boxes in any order you like.

Terms & Conditions. You need to fill all the boxes, No box should be empty

before giving it to me. I can ask you money in any whole number in two or three

times whose sum will not exceed to Rs.1000/ While giving for the money which I ask, you need to give

the whole box and not the portion of it. How can you fill?

INTERNET


Tim Berners Lee is the Father of Internet. He invented World wide web as well as HTML. Internet is nothing but the network of network. The term network denotes connection of two or more

computers to share the data (like Files) as well as resources. (like Printers, Scanners etc.,)

IP Address is the Address to identify any computer connected in the Internet.

WEB ADDRESS


URL – Uniform Resource Locator. http – hypertext Transfer Protocol. FTP – File Transfer Protocol. DNS – Domain Naming System. i.p Address – Internet Protocol Address Domain Names – com, org, net, edu, in, us,uk. www – world wide web. Wired / Wireless Networks.

Networking Basics


Types of Networks LAN – Local Area Network MAN – Metropolitan Area Network WAN – Wide Area Network Network Topologies. Star, Ring, Bus, Tree and Mesh Topologies
