 On the third week of August we learned about Computers Network and Hardware essentials which is under topic B01 and  Topic BO1 Network Communication  - Kilobit is one thousand bits. -kbps(kilobit per second) or KBps(Kilobytes per second) -K stands for 1024 and k stands for 1000 -Download speed and internet bandwidth depends on kbps (higher the kbps faster is the speed of the download) Components of networks hardware components need -NIC provides connection between the computer and the network. It is like chip that helps computer to connect connect to the network. -network medium can be air waves as in wireless and cable for NIC.  - interconnecting device. NIC Components of networks 1. Software components -network client and server  Client server- request information stored from another device Server software - allows device to share its resources. - protocols meaning rules -NIC driver forwards data to NIC(chip like) Layers of Network communication process 1.user application 2.network

Topic A03 Digital Representation. On second week i learned a new topic which is topic A03. Topic A03 was all about digital representation . what does ASCII stands for? - ASCII(American Standard Code for Information Interchange) - It is 7-bit characters code, with values from 0 to 127. - ASCII code is a subset of UTF-8 code. ASCII v/s Unicode ASCII is a 7-bit character code (0 to 7F)- hexa-decimal Unicode is a bigger set or superset of ASCII that contains ASCII code ranging from 0 to 10FFFF- hexa-decimal.   Representing sound - Sounds are usually waves and for them to be processed by computer sounds should be converted into binary form. - 0 & 1 is a binary number . Representing image - S ame like sounds image is also converted or broken into individual pixels. - each pixels actually has three emitters. (R- red , G - green, B- blue)  Representing number  - In computer most natural or appropriate way to represent a number is by string of bit called binary number. # binary number are 0
