COMPUTER JS 2A – 2D. WEEK 3

TOPIC: INTERNET

OBJECTIVES:

Define Internet, World Wide Web (WWW), Electronic mail, and website

Create an e-mail account

Write and send email

Internet is a collection of computers connected together through which information can be shared

worldwide. On the internet, information travels through a variety of languages known as protocol, and

each computer connected to the internet can communicate with other computers through the

transmission control protocol TCP or Internet protocol IP.

To read information on the internet, you need a program such as internet explorer.

World Wide Web:- it is a medium that allows people to get information that is available on the internet.

Examples are Www.yahoo.com, www.google.com.

Electronic mail (e-mail):- it is a means by which messages are sent and received electronically through the

internet. It is a file that is sent from one computer to another through a network. Some of these files are

texts, scanned images, computer graphics and sound video files, which can also be sent along with your

e-mail messages.

Advantages of e-mail

Messages can be sent at any time of the day at the sender’s convenience

It can save a lot of paper

One can transmit messages in a few seconds

A single email copy can be sent to multiple users.

Website:- it is a collection of related web pages, images, that are hosted on one web server usually

accessible through the internet.

Creating an email account.

Before one can send a mail, you need to have an email account. This allows you to send and receive email

messages. Some of the site where you can create an email account are

www.yahoo.com

www.hotmail.com

www.mail.com

Steps in creating an email account

1. Open internet explorer

2. Log in into any internet e-mail site such as www.yahoo.com or www.hotmail.com.

3. On the home page, click on signup.

4. A form will appear, then fill the form and click on “I AGREE”, instantly a new page will

appear which confirms your registration.

To open email account that has been created already,

Open your email account, type the site address you used eg. www.yahoo.com in the address bar

of the internet explorer window and press the enter key. A page will appear

Type your email address and password.

Click on sign in or press enter key in the keyboard.

Note:-. Email addresses have a set arrangement.

1. The user name

2. The @ sign

3. The domain.

Examples of email addresses are Godloves@yahoo.com, staysafe@hotmail.com,

onyiforchrist@gmail.com . Then user name in this is Godloves which identifies whose e-mail it is.

The @ sign tells you that the user is at the domain. Domain is example, yahoo.com; the part after the @

sign and before the dot (i.e yahoo) tells you which service provider the user’s email is from.

Sending email messages

Go to the home page address you are using

Click on check email.

Supply your ID and password, click on sign in or press enter key on the keyboard

Click on compose for yahoo, if is other site, click on write mail and the window will show up

something like this: To, Cc, subject.

Type in the address of the recipient in a box at the top of the window called to

Type in the email address of anyone else you would like to send the email to in a box called cc.

Then type in the subject of your email in a box for ‘subject'

Finally click on the sent button to mail your letter.

See the picture below

Evaluation/Assignment.

TOPIC Benefit of Internet, Internet Abuses.

OBJECTIVES:-

State the benefit of Internet

Outline the abuses of Internet

The use of Internet offers a variety of benefits to everyone who is willing to use it. The internet reduces

distances and provides communication services efficiently and without any cost. It is a multi-tool with

LESSON NOTE FOR WEEK THREESUBJECT: P.H.ECLASS: J.S.S 2TOPIC: JOINTS IN THE HUMANBODY.

PERFORMANCE OBJECTIVES: Bythe end of the lesson, the studentsshould be able to:1.Explain what a joint is.2.Mention the types of joints in thehuman body.3.Mention the types of synovialjoints we have.4.Mention the functions of joints inthe human body.

A joint is a site at which any two ormore bones come together. If theends of hard bones are constantlyrubbing together, they would wearaway. However, each movable jointhas cushions of cartilages and isenclosed by a tough membrane orligament fused to the bones oneither side of the joints. There are

about 400 joints in the human body.Some are immovable, partiallymovable or limited movement andothers have free movements.

TYPES OF JOINTS 1. Fibrous or Fixed Joints: There arefibrous or fixed joints which arelocated in the sutures of the skulland the teeth in their sockets .Theydo not move.

2. Cartileginous or Slightly movablejoints: There is a pad of white fibrocartilage between the ends of thebones.The cartilage between thebones can be compressed, hencethis type of joint allows for slightmovements. Cartilage joints arefound in the symphsis pubis (hipjoint and the joints between thebones of the vertebrae.

3. Synovial or Freely movable joints:These joints permit a wide range ofmovements .The synovial joints

have synovial membranes andfluids .Synovial free movable jointsare found around the shoulder, thehip joints, elbow, knees, ankles, atlasand the occipital bones.Synovial joint types include: 1. Ball and socket joint: This is alsocalled universal joints and allow thefreest motion of all. Examples arethe humerus and scapula formingthe shoulder girdle and the femurand the pelvis forming the hip girdle.Movements in all planes is madepossible by this type of joint.

2. Hinge joints: The knees, elbowsand the finger joints allowmovements only in one plane ordirection like in closing the doors. Inthe elbow, the hinge is between thefemur and tibia.

3 .Pivot or rotating joint: The headcan move from side to side becausethe skull rests on the atlas .Such ajoint permits nodding. The radius

pivots over the Ulna below theelbow. This allows the radius tomove the palm of the hand up ordown .When your palm is upward(Supination), the two bones arenearly parallel. When your palm isdownward (Pronation), the radius onthe side of the thumbs has rotatedover the Ulna.

4. Gliding joints: Bones which haveconcave or convex surfaces glideover each other and produce limitedmovements .The bones of the wrist(carpals) and those of the ankles(tarsals) allow slight glidingmovement, so do the articularfacets between the vertebrae andthe joints between the rib heads andfacets of the thoracic vertebrae.

FUNCTIONS OF THE JOINTS 1.They link bones together.2.They allow movements in manydirections.3.Cartilages cushion the

intersections between bones.4.They absorb synovial fluids.5. They bind the skeleton together.6. They give structures and allowmuscles to move bones to performtasks.7. They bear weights.

EVALUATION: 1.What is a joint?2. Mention the type of joints youstudied.3. Where are ball, socket and hingejoints located in the body?4.What are the functions of joints ?

ASSIGNMENT: Read through thedescriptions of the joints andpractice the movements possible atsuch joints .
