Different types of computer networks are:
1. LAN(Local Area Network):
(i) The local area network is a network which is designed to operate over a small physical area such as an office, factory or a group of buildings. LAN are widely used in variety of applications.
(ii) In LAN all the machines are connected to a single cable. Different topologies such as Bus, Ring, Star, Tree, etc. are used for LANs.
(iii) The size of LAN is usually small. The various devices in LAN are connected to central devices called Hub or Switch using a cable.
(iv) A LAN is usually a privately owned and links the devices in a single office, building or campus of up to few kilometres in size.
(v) The data rate for LAN can now range from 4 to 16 Mbps.
2. MAN(Metropolitan Area Network):
(i) A MAN is basically a bigger version of LAN. It is designed to extend over the entire city. MANs extend beyond 100 KM.
(ii) The MAN can be in the form of a single network such as a cable network or it can be a combination of multiple LANs.
(iii) A MAN may be wholly owned and operated by a private company or it may be a service provided by a public company, such as local telephone company(telco).
3. WAN(Wide area network):
(i) When a network spans a large distance or when the computers to be connected to each other are at wide separated locations a local area network cannot be used. For such situation, a Wide area Network(WAN) must be installed.
(ii) The communication between different users of WAN is established using leased telephone lines or satellite links and similar channels.
(iii) A WAN provides a long-distance transmission of data, voice image and video information over large geographical areas that may comprise a country, a continent or even the whole world.
(iv) WANs may use public, leased or private communication devices, and can spread over a wide geographical area. WAN that is wholly owned and used by a single company is often called as enterprise network.
(v) In most WANs the network contains a large number of cables or telephone lines each one connecting a pair of routers.
4. PAN (Personal area network):
(i) A personal area network, or PAN, is a computer network that enables communication between computer devices.
(ii) PANs can be wired, such as USB or FireWire, or they can be wireless, such as infrared, ZigBee, Bluetooth and ultra-wide band (UWB).
(iii) The range of a PAN typically is a few meters. Examples of wireless PAN (WPAN) are devices include cell phone, headsets, wireless keyboards, wireless mice, printers, bar code scanners and game consoles.
(iv) Hence computer network are classified into four types based on the size, distance and the structure namely: LAN (Local Area Network), MAN (Metropolitan Area Network), WAN (Wide Area Network) and PAN (Personal Area Network).

(i) The size of the instruction set is another important consideration while categorizing microprocessors.
(ii) Initially, microprocessors had very small instruction sets because complex hardware was expensive as well as difficult to build.
(iii) As technology had developed to overcome these issues, more and more complex instructions were added to increase the functionality of the microprocessor,
(iv) Let us learn more about the two types of microprocessors which are based on their instruction sets.
(v) RISC stands for Reduced Instruction Set Computers. They have a small set of highly optimized instructions.
(vi) Complex instructions are also implemented using simpler instructions, thus reducing the size of the instruction set.
(vii) Examples of RISC processors are Intel P6, Pentium IV, AMD K6 and K7.
(viii) CISC stands for Complex Instruction Set Computers. They support hundreds of instructions. Computers supporting CISC can accomplish a wide variety of tasks, making them ideal for personal computers.
(ix) Examples of CISC processors are Intel 386 & 486, Pentium, Pentium II and III, and Motorola 68000.

Non-Impact Printers:
(i) These printers do not use striking mechanism for printing. They use electrostatic or laser technology.
(ii) Quality and speed of these printers are better than Impact printers. For example, Laser printers and Inkjet printers are non-impact printers.
Laser Printers:
(i) Laser printers mostly work with similar technology used by photocopiers.
(ii) It makes a laser beam scan back and forth across a drum inside the printer, building up a pattern. It can produce very good quality of graphic images.
(iii) One of the chief characteristics of laser printer is their resolution - how many Dots per inch(DPI). The available resolution range around 1200 dpi. Approximately it can print 100 pages per minute(PPM).

Inkjet Printers:
(i) Inkjet Printers use colour cartridges which combined Magenta, Yellow and Cyan inks to create color tones.
(ii) A black cartridge is also used for monochrome output. Inkjet printers work by spraying ionised ink at a sheet of paper.
(iii) The speed of Inkjet printers generally ranges from 1-20 PPM (Page Per Minute).
(iv) They use the technology offering ink by heating it so that it explodes towards the paper in bubbles or by using piezoelectricity in which tiny electric currents controlled by electronic circuits are used inside the printer to spread ink in jet speed.
(v) An Inkjet printer can spread millions of dots of ink at the paper every single second.

The header is a section of the document that appears in the top margin, while the footer is a section of the document that appears in the bottom margin of the page. Typically, headers display the title or chapter name, author name of a document while the footer displays the page number, date, time etc which gets displayed on all the pages automatically.
To Insert Headers and Footers:
(i) Select from the main menu Insert -> Header -> Default
(ii) The header text area is separated from the normal text are (a)
(iii) Enter the text that is to be repeated in all pages or Select Insert -> Fields -> Title.

The Linux operating system was originated in 1991, as a project of "Linus Torvalds" from a university student of Finland. He posted information about his project on a newsgroup for computer students and programmers. He received support and assistance from volunteers who succeeded in creating a complete and functional operating system. Linux is similar to UNIX operating system.

(ii) The left most bit in the binary number is called as the Most Significant Bit (MSB) and it has the largest positional weight.
(iii) The right most bit is the Least Significant Bit (LSB) and has the smallest positional weight.

There are many good options, though. Let’s take a look at the best Android keyboards !
(i) SwiftKey is definitely among the best Android keyboards ever. It has top of the line prediction and auto-correction along with gesture typing, cloud syncing so all of your devices can stay up to date, themes, keyboard customization, a number row, and more....

(ii) There are a number of different arrangements of alphabetic, numeric, and punctuation symbols on keys. These different keyboard layouts arise mainly because different people need easy access to different symbols, either because they are inputting text in different languages, or because they need a specialized layout for mathematics, accounting, computer programming, or other purposes..
