FAX: {You are able to|You may} send and receive faxed documents on your computer without {by using a} fax machine. You can also {printing|print out|produce}, e-mail or save a duplicate of your fax. To get start:

{Slots|Plug-ins|Jacks}: A port is an interface or point of attachment. It {can be used|is employed} to {hook up} peripheral devices with computer such as {inkjet printer|printing device|computer printer}, Keyboard or mouse. {Almost all|Most|Every} peripheral devices communicate with computer using ports. The ports connecters are fastened to motherboard. Each type of port operates at a certain speed. The speed is measured in Kilobits per second (Kbps) or megabits per second (Mbps).

{Years|Ages} of Computer The development of electronic computers can be {split up into} generations depending {after} the technologies used. The generations of {personal computers are|pcs are} the following: -    First {era|technology} (Vacuum Tube) 1942-1955 -    Second generation (Transistor) 1955-1964 -    Third generation (Integrate Circuits) 1964-1975 -    Fourth generation (Microprocessor) 1975-Present -    Fifth generation (Artificial intelligence) Present & {Over and above|Further than}

{Arbitrary|Randomly|Unique} Access Memory (RAM): {Ram memory|Memory|Good old ram} stands for random gain access to memory. It is also called direct access {memory space|storage|recollection}. Random access means that every individual byte in entire memory can be accessed directly. RAM {can be used|is employed} to maintain data and instructions temporarily. A program must be loaded into RAM before execution. Types of RAM:

Read-Only Memory (ROM): ROM {means|is short for} read only memory. The instructions in ROM {put together|make} the computer for use. These instructions can only be read but {are not able to|are unable to|simply cannot} be changed or {erased|removed|wiped}. It is not possible to write new information or instructions {in to the|in the} RANGE OF MOTION. ROM stores data and instructions permanently. If the power is switched off, the instructions stored in ROM {are certainly not|aren't|are generally not} lost. {Consequently|As a result|For that reason} ROM {is known as|is named|is referred to as} non-volatile {memory space|storage|recollection}. The information in RANGE OF MOTION is stored by the manufacturer. When the computer is switched on, the instructions in the RANGE OF MOTION are automatically loaded into the memory of the computer. ROM contains {a tiny} set of instructions called ROM BIOS. BIOS stand for input/output system. {These types of|These kinds of} instructions tel

Mouse button: A mouse is {a tiny} device that a computer user pushes across a desk surface in order to {indicate} a place on a screen {display screen} {and} select {a number of|more than one} actions to take {because of this|therefore} position. The mouse first became a widely-used computer tool when Apple {Pc|Computer system|Laptop} made it {a typical|a regular|a normal} part of the Apple {Mac pc}. Today, the mouse is {a fundamental element of|an important part of} the gui (GUI) of any {computer|laptop or computer}. The mouse button apparently {received|acquired} thier name by being about the same size and color as a toy mouse button.

Step-1:   click on the Insert Menu, and then go to Subgroup ‘Illustrations’ and select the  Shape Command, here is a lot of Shapes Shown and select any one of them. Step-2:    There is a shape that I select from  “Insert Menu”. Now I want to change the  perimeters of it.

{Pc|Computer system|Laptop} Computer is an {digital|electric|electronic digital} device that {can be used|is employed} to solve various problems to a set of {training|teaching|instructions} given to it. A computer can accept data, process data into useful information and store it for later use. Types of computer Computer can be divided into the following types on the basis of their working. Analog Computer : An analog computer does not operate with digital signals. {This|That} recognizes data as a continuous measurement of physical properties. It has no state. Analog computer is difficult to operate and use. Its output is usually displayed on a meter graphs. Voltage, pressure, speed and temperature are some physical properties that can be measured in this way. Analog has low memory and fewer functions. It is usually {created for|intended for} special purposes. Analog computer is mainly used in the field of engineering and medicine.

{How|The way} data is transmitted {in one|from|from a single} {location to|destination to} another is called data transmission mode. Types of Transmission Modes: {Presently there are|Right now there are|Generally there are} three types of data transmission modes: Simplex mode Half duplex {setting|function|method} Full duplex {setting|function|method} Simplex mode: In simplex {setting|function|method}, data can flow only in one direction. {It may|It could|It might} not be moved in both direction. It are operating in a manner similar to an {visible|verified|do follow} street. The direction of flow never changes. A tool with simplex {setting|function|method} can send or {get|obtain|acquire} data. It can not perform both actions. Model}: An example is a traditional {tv set|television set} broadcast. The signal is send from a transmitter to {TELEVISION|TV SET|TELEVISION SET} antenna. There is no return signal. Half {Appartment building|De dos pisos} Mode: By 50 % duplex

Tangible parts computer are called hardware . These are physical computers of the computer. Types of Hardware: Input Unit The devices used to provide data, instruction & control signal to computer are collectively called as input. Key board, pointing devices, scanning devices etc are examples Output Unit

Network Topologies A network can be configured {in several} ways. The physical layout of {linked} devices in a network is called topology. {It's the|Is it doesn't} {condition} of a network. Different network topologies are the following; {Coach|Tour bus|Shuttle bus} Topology Ring Topology {Celebrity|Superstar|Legend} Topology Tree Topology {Fine mesh|Nylon uppers|Webbing} Topology Bus Topology {Coach|Tour bus|Shuttle bus} topology is {the easiest|the best|most effective} type of network. It {facilitates|helps} {a tiny} number of {computer systems|personal computers|pcs}. In Bus topology, all computers are {linked} to one common communication medium. This medium is often a central wire known as Bus. The terminators {are being used} at the end of a bus to absorb signals. A {crash|accident|impact} can occur in {coach|tour bus|shuttle bus} topology if two {computer systems|personal computers|pcs} transmit data at same time.

The dominant word processing program for private computers in the 1980s was DOS-based WordPerfect . Microsoft Word for DOS, which had recently been released in 1983, was an also-ran. That situation changed {significantly|considerably|drastically} with {the creation of|the development of} Microsoft Word for {Home windows|House windows|Glass windows} in 1989. By 93 it was {producing|creating|making} {50 percent|fifty percent} of the word {digesting|control|finalizing} market revenue, and by 1997 it was up to 90%. [1] word_processor_market_share
