Using Software: Spreadsheet I- Presentation Introduction: Excel 2013 is a spreadsheet program that allows you to store,organize, and analyze information and execute calculations automatically . While you may believe Excel is only used by certain people to process complicated data, anyone can learn how to take advantage of the program's powerful features. Whether you're keeping a budget, organizing a training log, or creating an invoice, Excel makes it easy to work with different types of data.

Getting to know Excel 2013 Excel 2013 is similar to Excel 2010. If you've previously used Excel 2010, Excel 2013 should feel familiar. If you are new to Excel or have more experience with older versions, you should first take some time to become familiar with the Excel 2013 interface.

Basic Terminology â–Ş A cell is the intersection between a line (horizontal) and a column (vertical) on a worksheet. Thus, the name (reference) of the line combined with the name (reference) of the column gives the cell's reference (the terms address or coordinates are also used). â–Ş A spreadsheet is a table used to store various types of data. The data is arranged in rows and columns.

II- Presentation of Microsoft Excel 2.1- Start with MS-Excel When you open Excel 2013 for the first time, the Excel Start Screen will appear. From here, you'll be able to create a new workbook, choose a template, and access your recently edited workbooks.

From the Excel Start Screen, locate and select Blank workbook to access the Excel interface.

To start Microsoft Excel (see screenshot below): 1. Click the Start menu.

AY 2017/2018

Math Operators and the Order of Operations Math Operators The six mathematical operators you need to know to enter basic formulas in Excel are: 1. Addition. Plus sign (+).

2. Subtraction. Minus sign (-).

3. Multiplication. Asterisk (*).

4. Division. Forward slash (/).

5. Percent. Percent sign (%).

6. Exponentiation. Exponents sign (^).

•

Math Operators

When a formula uses more than one operator, the order of operations in Excel is as follows: 1. Parentheses. Operations contained in parentheses (or brackets) are executed first.

2. Exponents. Exponents are executed second.

3. Multiplication / Division. Multiplication and division, which Excel treats equally, are executed third, from left to right.

4. Addition / Subtraction. Addition and subtraction, which Excel treats equally, are executed last, from left to right.

➢ Entering Formulas The simplest (not always the easiest) way to enter a formula in Excel is to: 1. Select the cell in which you wish to enter a formula.

2. Press "=" on your keyboard.

3. Select the first cell which contains data you will use in your formula.

4. Type the operator (+, -, *, or /).

5. Select the second cell which contains data you will use in your formula.

6. If necessary, type additional operators and select additional cells. If some operations should be performed before others, enclose those operations in parentheses.

➢ AutoSum (and Other Common Auto-Formulas) Some formulas can be entered simply by clicking a button in Excel. Excel will even guess which data the formula applies to, meaning that if your spreadsheet is properly laid out, you don't have to select the cells.

AutoSum: To quickly sum a row or column of data:

AY 2017/2018

• Syntax: =AVERAGE(number1;number2;number3;…) means to calculate In the cell G4 =AVERAGE (C4;D4;E4;F4) =AVERAGE (number1:number6) means to calculate In the cell G4 =AVERAGE (C4:F4)

Exercise (School Report) Complete the column Rank which returns the rank of each pupil average with the other averages.

Interpretation:

 We have to • •

use the predefined function RANK This function returns the rank of a number in a list of numbers Syntax: =RANK (number; ref; [order])

Number: is the number for which you want to find the rank Ref: is an array of, or a reference to, a list of numbers. Nonnumeric values in ref are ignored.

Order: is a number specifying how to rank number.

If order is 0 (zero) or omitted, Microsoft Excel ranks number as if ref were a list sorted in descending order; else (any nonzero value) sorted in ascending order.

Exercise (School Report)  the function MAX returns the largest value in a set of values.

Syntax: MAX(number1,number2,...) E.g.

or

MAX(D2:D20) returns the biggest value in the range D2:D20.

For another example, MAX(D4; D6; D13; D19) returns the biggest value from values contained in cells D4, D6, D13 and D19.

 The MIN function returns the smallest number in a set of values.

Syntax: MIN(number1,number2,...) e.g.

MIN(C3:C11) returns the smallest number in the range C3:C11. For another example, MIN(C3; C9; C11) returns the smallest number from numbers contained in cells C3, C9 and C11.  the function COUNT which returns the number of cells containing numbers.

Syntax: COUNT(value1, [value2],...)

 The use of the function COUNTIF which returns the number of cells containing numbers with condition.

Syntax:

=COUNTIF (range, criteria)

Pioneer Middle School of Sfax

25

The COUNTIF function syntax has the following arguments: Range Required one or more cells to count, including numbers or names, arrays, or references that contain numbers. Blank and text values are ignored.

Criteria Required. A number, expression, cell reference, or text string that defines which cells will be counted.

Conditional structure Complete the column Result as follows: • Result = “Success” if the pupil average >=10 • Result= “Failure “if Pupil Average <10 Task:

Interpretation: • We can use of the function “IF” having the following expression: Syntax:

=IF(logical_test; value_if_true; value_if_false)

 We have to use nested IF in the place of “value_if_false”.

Exercise (School Report) : Complete the column Result as follows: • Result = “Success” if the pupil average >=10 • Result= “Redemption “ if Redemption Average<=pupil average<10 • Result= “Failure “if Pupil Average< Redemption Average In the I4 cell you have to insert the function this way:

In the cell I4, we type the formula

=IF(G4>=10;"succes";IF(G4>H$2;"Redemption";"Failure"))

then we drag

VIII- Visualizing Your Data: WORKING WITH CHARTS It is often useful to visualize data, and it's easy to do so in Excel using charts. The most commonly used chart types are: 1. Column. Column charts are commonly used to compare values of different items.

2. Line. Line charts are commonly used to show trends.

3. Pie. Pie charts are useful when you have only one set of data and want to show how much of the whole each item accounts for.

4. Bar. Bar charts are similar to column charts except that the bars are displayed horizontally instead of vertically.

5. Area. Area charts are similar to line trends in that they show trends, but the data is stacked, making it easy to compare different values over time.

6. Scatter. Scatter charts are used to display two variables, one along the X-axis and one on the Yaxis, for a single set of data.

8.1- Inserting Charts To insert a chart into an Excel workbook: 1. Select the data you wish to display. If Excel recognizes your data as being a list, you can select any cell within the list.

Local Area Networks (LAN) is a network that is confined to a relatively ………….. area. LAN network is one of the commonly used network and one of the simplest. This network connects computer over a small distance such as within a building or a single computer lab consisting of many computers. This network do not contain more than one subnet because they are controlled by one administrator. Advantage of using this network is small distance data sharing cause less errors and noise are minimum. Data transfer rate is 10 to 100 mbps. Coaxial cable and CAT 5 cables are normally used for connection.

WAN (…………….. Area Network) spans a ……………….. physical distance.

This network is slightly more complex in nature by connecting computers together over a large distance. The network capable to remotely connecting computers over a huge network and allowing them to communicate even when they are far apart. This network contain multiple LANs and MANs network such as internet using routers to transfer data or information faster and securely. MAN network is distinguished from other network in terms of geographical range. Data transfer rate in this network depends upon ISP provider and varies over the location. Sometimes it also use satellites and microwave relays. Example of WAN is Internet.

•

Metropolitan Area Network (MAN )

This network is same as LAN but cover a distance an entire city or campus and formally connected with LAN. This network is larger than LAN but smaller than WAN network that we discuss later.

Transmission media used by this network is fibre optic cables which provide efficient and fast communication. This network can be up to 5 to 50 km but data transfer rate is low as compared to LAN. MAN network is owned by organization and individuals like organization with the different branches located in the city.

MAN is the right network to build a network between offices in the city of factories / establishments and headquarters are within its range.

AY 2017/2018

I-2-B : Advantages of Networks : File Sharing The major advantage of a computer network is that is allows file sharing and remote file access. A person sitting at one workstation that is connected to a network can easily see files present on another workstation, provided he is authorized to do so. This saves him/her the hassle of carrying a storage device every time data needs to be transported from one system to another. Further, a central database means that anyone on that network can access a file and/or update it. If files are stored on a server and all of its clients share that storage capacity, then it becomes easier to make a file available to multiple users.

Resource Sharing Resource sharing is another important benefit of a computer network. For example, if there are twelve employees in an organization, each having their own computer, they will require twelve modems and twelve printers if they want to use the resources at the same time. A computer network, on the other hand, provides a cheaper alternative by the provision of resource sharing.

All the computers can be interconnected using a network, and just one modem and printer can efficiently provide the services to all twelve users.

Inexpensive Set-Up Shared resources mean reduction in hardware costs. Shared files mean reduction in memory requirement, which indirectly means reduction in file storage expenses. A particular software can be installed only once on the server and made available across all connected computers at once.

This saves the expense of buying and installing the same software as many times for as many users.

Flexible Handling A user can log on to a computer anywhere on the network and access his files. This offers flexibility to the user as to where he should be during the course of his routine. A network also allows the network administrator to choose which user on the network has what specific permissions to handle a file. For example, the network administrator can allot different permissions to User A and User B for File XYZ. According to these permissions, User A can read and modify File XYZ, but User B cannot modify the file. The permission set for User B is readonly. This offers immense flexibility against unwarranted access to important data.

Increased Storage Capacity Since there is more than one computer on a network which can easily share files, the issue of storage capacity gets resolved to a great extent. A standalone computer might fall short of storage memory, but when many computers are on a network, the memory of different computers can be used in such a case. One can also design a storage server on the network in order to have a huge storage capacity.

LAN vs. WAN: Differences Between LAN and WAN The two most popular network types today are LAN (Local Area Network) and WAN (Wide Area Network). These two networks are generally classified on the basis of their coverage area. Given below are few points that differentiate these two networks.

Typically, a local area network exists in a house or a university campus, while a wide area network exists over many office buildings separated by a vast distance. The office buildings in a WAN may be in different countries or even continents.

For example, the headquarters may be in USA, the regional office may be in the UK, and the branch office may be in India. The workers in these three buildings use a Wide Area Network to collaborate with each other. The Internet can also be considered as a WAN, with the Ethernet being a classic example of WAN. Let us have a look at the two structures and their differences.

I-2-C- Data Transfer Rate:



The Data Transfer Rate (DTR) is the speed at which data can be transmitted between devices.

It’s often expressed in KB per second (KB/s) or MB/s. it depends on the distance, the quality of the line, and the wire gauge.

Observation: The difference between these networks is in their:

Shape, Structure, layout pattern is the physical communication schema used by connected devices.

What means Network Topology?

Activity 6: fill the blanks using these terms: nodes, the shape, Links, layout.

Network Topology refers to the shape or the layout, structure, architecture of a computer network. It determines how different links and nodes (Computer, printer, modem…) are connected to each other in a network and It’s the schematic description of how they communicate.

A physical topology describes how network devices are physically connected - how devices are actually plugged into each other. We're talking about cables, wireless connectivity, etc.

A logical topology describes how network devices appear to be connected to each other.

Activity 7: Try to search from the Internet the different kinds of network topologies.

There are many network topologies (used in LANs) such as: Bus Topology:

All devices are connected to a central cable called the bus, which is the backbone.

Bus networks are relatively inexpensive and easy to install for small networks but hard for troubleshooting (in case there’s a problem) Ring Network Topology: All devices are connected to one another in the shape of a closed loop. Ring topologies are relatively expensive and difficult to install, but they offer high data transfer rate and can span large distances.

9th grade Unit: Computer Networks and FTP service

AY 2017/2018

Star Network Topology: ➢ All devices are connected to central equipment: hub. Star networks are relatively easy to install and manage. All data must pass through the hub ➢

Tree Topology: integrate multiple star topologies together onto

a bus. In its simplest form, only hub devices connect directly to the tree bus and each hub functions as the "root" of a tree of devices. This bus/star hybrid approach supports future expandability of the network much better than a bus (limited in the number of devices due to the broadcast traffic it generates) or a star (limited by the number of hub connection points) alone.

Evaluation3: Enumerate the advantages and the disadvantages of each network topology?

Advantages:

Bus topology • Simple and easy to set up • Good for small networks not requiring higher speeds.

• Cheaper than other topologies.

Pioneer Preparatory School of Sfax

Ring topology • Offer higher data transfer rate • Can span large distances (in a LAN).

• It is less costly than a star topology.

46

Star topology • A fault on one of the nodes will not affect the rest of the network • More performance than other topologies • Easy to install and manage.

Teacher: Mrs. IMEN TEKAYA BOUAZIZ

9th grade Unit: Computer Networks and FTP service

AY 2017/2018

Disadvantages:

Bus topology Limited cable length and limited number of nodes.

If there is a problem with the cable or one node fails, the entire network goes down.

Low security

Ring topology More expensive than the Bus Top and difficult to install.

Star topology The failure of the hub makes the network inoperable.

Any moves, adds and changes of devices can affect the network.

Data packets must pass through every computer between the sender and recipient therefore this makes it slower.

Cabling more expensive and Extra hardware required (hub , switch)

If any of the nodes fail then the ring is broken and data cannot be transmitted successfully.

The file Transfer Protocol is an Internet service: (FTP) is a standard Internet protocol for transmitting files between computers on the Internet over TCP/IP connections.

http://encyclopedia.kids.net.au/page/ft/FTP Transferring files from a client computer to a server computer is called "uploading" and transferring from a server to a client is "downloading".

FTP is a client-server protocol that relies on two communications channels between client and server: a command channel for controlling the conversation and a data channel for transmitting file content. Clients initiate conversations with servers by requesting to download a file. Using FTP, a client can upload, download, delete, rename, move and copy files on a server.

1- Downloading The file downloading is an Internet service. It allows to copy and to transfer information (Text, image, sound, and video) online.

In computer networks, to download means to transfer a file or program from a central computer to a smaller computer or to a computer at a remote location The inverse operation is called uploading. It means sending data from a local system to a remote system such as a server or another client.

Activity 9: You note that the software Photofiltre is free to download. You note that the software Photofiltre Studio X is not free to download.

Using the Internet, produce a presentation to compare of these new terms: Shareware, Freeware and Premium version

Shareware Is a copyrighted computer software (other people can't market the software as their own) a) Trial version: that typically is available free of charge for trial use (after 30 days for example, the user can no longer get access to the program).but that must be paid for by anyone who uses it regularly.

Example: antivirus

Freeware is copyrighted software you can download, pass around, and distribute without any initial payment.

The great part about freeware is that you never have to pay for it. No 30 day limit, no demo versions, no disabled features -- it's totally free.

Examples: Audacity, windows media player, Paint, Browsers, VLC, Adobe Flash Player ,â&#x20AC;Ś

b) liteware is a sort of shareware which is distributed freely in a version having less capability than the full for-sale version(premium version)but no limited trial period. ex: games, Pop messenger, Photofiltre studio X, Microsoft office,...
