1. TSCII (Tamil Script Code for Information Interchange) is the first coding system to handle our Tamil language.
2. This encoding scheme was registered in IANA (Internet Assigned Numbers Authority) a unit of ICANN.
3. This is one of the encoding schemes specially designed for Indian languages including Tamil. It was unified with Unicode.
4. Unicode is an encoding system, designed to handle various world languages, including Tamil. Its first version 1.0.0 was introduced in October 1991. Unicode is the best suitable to handle Tamil.
5. Computers use ASCll encoding system to handle data and information. because computers handle data and information as binary system. But ASCII encoding system is applicable only for handling English language. So TSCII (Tamil Script Code for Information Interchange) came in demand.

1. A protocol suite is defined as the set of protocols organized in different layers. The TCP/IP protocol suite is used in internet today.
2. TCP/IP stands for Transmission Control Protocol/Internet Protocol, is the standard internet communications protocols that allow digital computers to communicate over long distances.
3. The internet is a packet-switched network, in which information is broken down into small packets, sent individually over many different rotes at the same time, and then reassembled at the receiving end.
4. TCP is a component that collects and reassembles the packets of data, while $\mathbb{I}$ is responsible for making sure the packets are sent to the right destination.
5. TCP/IP is a hierarchical protocol suite means that each upper layer protocol receives support and services from either one or more lower-level protocols.

iOS - iPhone OS
iOS (formerly iPhone OS) is a mobile operating system created and developed by Apple Inc. exclusively for its hardware. It is the operating system that presently powers many of the company's mobile devices, including the iPhone, iPad and iPod Touch. It is the second most popular mobile operating system globally after Android.

(i) The main memory is otherwise called as Random Access Memory. This is available in computers in the form of Integrated Circuits (lCs). It is the place in a computer where the Operating System, Application Programs and the data in current use are kept temporarily so that they can be accessed by the computer's processor.
(ii) The smallest unit of information that can be stored in the memory is called as a bit. The memory can be accessed by a collection of 8 bits which is called as a byte.
(iii) The bytes are referred by 'B'. If a computer has 1 megabyte of memory, then it can store 10,48,576 bytes. (or characters) of information. [Hence 1MB is 1024KB and 1 KB is 1024 Bytes, So 1024X1024 =10,48,576 Bytes].
(iv) RAM is a volatile memory, which means that the information stored init is not permanent. As soon as the power is turned off, whatever data that resides in RAM is lost. It allows both read and write operations.
(v) There are two basic types of RAM Dynamic RAM (DRAM), Static RAM (SRAM).
(vi) These two types differ in the technology they use to hold data. Dynamic RAM being a common type needs to be refreshed frequently. Static RAM needs to be refreshed less often, which makes it faster.
(vii) Hence, Static RAM is more expensive than Dynamic RAM.

(ii) For example, Dot Matrix printers and Line matrix printers are impact printers.
(iii) A Dot matrix printer that prints using a fixed number of pins or wires. Each dot is produced by a tiny metal rod, also called a "wire" or "pin", which works by the power of a tiny electromagnet or solenoid, either directly or through a set of small levers.
(iv) It generally prints one line of text at a time. The printing speed of these printers varies from 30 to 1550 CPS (Character Per Second).
