Bibliografie
Introducere
in HTML
HTML este
prescurtarea de la Hyper Text Mark-up Language si este codul care sta la
baza paginilor web. Paginile HTML contin elemente (etichete) si au extensia .html
sau .htm.
Puteti
scrie astfel de fisiere cu Notepad sau cel mai indicat cu un editor
specializat, de exemplu Crimson Editor, care va indica si numarul liniilor,
lucru util la depanarea codului HTML. Verificati ca nu aveti extensiile ascunse
(My Computer -> Tools -> Folder Options -> View -> debifati Hide
extensions for known file types). Pentru a putea crea fisiere html dati clic
dreapta New -> Text Document, apoi il redenumiti index.html.
Elemetele
sunt incadrate de tag-uri. Tag-urile sunt simbolurile care marcheaza inceputul
si sfarsitul unui element. Tag-ul pentru inceput este < iar pentru sfarsit
este >.
In
marea lor majoritate elementele sunt pereche, una de deschidere
<eticheta> si alta de inchidere </eticheta>. Browserul
interpreteaza aceste etichete afisand rezultatul pe ecran. HTML nu este un
limbaj case sensitiv (nu face deosebirea intre litere mici si mari).
Pagina
principala a unui domeniu este fisierul index.html. Aceasta pagina este
setata a fi afisata automat la vizitarea unui domeniu.
De exemplu la vizitarea domeniului www.nume.ro este afisata pagina www.nume.ro/index.html.
Unele
etichete permit utilizarea de atribute care pot avea anumite valori:
<eticheta atribut="valoare"> ... </eticheta>
Componenta
unui document HTML este:
1. versiunea HTML a documentului
2. zona head cu etichetele <head> </head>
3. zona body cu etichetele <body> </body>
sau <frameset> </frameset>

Ce este o pagina HTML? -HTTP s-ar traduce
prin limbaj de marcare, iar o pagina http este o pagina in format text care
contine <strong>tag-uri</strong> de marcare
· &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p;
Ce sunt tag-urile? - Tag-urile sunt niste coduri
care "spun" browser-ului cum sa afiseze pagina web.
· &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p;
Extensia paginii scrisa in limbajul HTML? -
Pagina trebuie sa aiba obligatoriu extensia .html (ex.:numepagina.html)
· &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p;
Cum poate fi scrisa o pagina web in html?
- Cel mai simplu mod(pentru utilizatorii windows) se poate scrie intr-un editor
de text ca Notepad(Start/Programs/Accesories/Notepad).
· &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p;
Cum se face prima pagina in html? -Prima
pagina a oricarui site se numeste index.html
:: Deschideti Notepad;acesta se deschide automat cu un fisier de text gol
nedenumit
:: Scrieti urmatorul cod in editor:
<html>
<head>
<title>Titlul paginii</title>
</head>
<body>
Aceasta este prima mea pagina in html.
Iar acesta este primul meu
text formatat ingrosat(eng.bold)
</body>
</html>
cind ati terminat de copiat codul in
editorul Notepad va duceti in file/save with name -adica il salvati cu un
nume,il numiti index.html.
-Nota:salvati-l in desktop ca sa puteti sa-l gasiti imediat si
verificati sa aiba la sfirsit extensia .html
· &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p;
Cum
verifici daca ai creat pagina bine?
-Te duci in desktop si cauti pagina denumita index.html, dai clic pe ea moment
in care se deschide internet explorer care-ti afiseaza o pagina web pe fond alb
cu mesajul scris de tine :
Aceasta este prima mea pagina in html (text normal) Iar acesta este primul meu
text formatat ingrosat(eng.bold)(text ingrosat) Despre cum se pune o pagina web
pe un Webserver vom vorbi in sectiunea FTP. .
· &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p; &nbs 717r1718h p;
Ce reprezinta ceea ce am scis in pagina mai
sus? Ca sa intelegeti mai bine vom descrie fiecare element al paginii: -<html>
acest tag spune browser-ului ca aceasta este o pagina scrisa in
hyper text markup language
-</html> acest tag spune browser-ului ca aici se termina
documentul sau pagina scrisa in html
-ceea ce se gaseste in tag-urile <head> si
<strong></head></strong> este informatia initiala la care are
acces browser-ul dar care nu este afisata pe ecran(exemplu: aici se pune titlul
paginii etc...)
- intre tag-urile <title> si </title> se scrie titlul
paginii informatie pe care o afiseaza in prima linie a fiecarui rezultat gasit,
majoriatatea motoarelor de cautare cum ar fi google,altavista etc...aceste
tag-uri trebuie neaparat sa se gaseasca in interiorul tag-urilor
<head></head>
-tot ceea ce se gaseste in interiorul tag-urilor <body> si </body>
este continutul care este afisat pe ecran in cazul nostru:Aceasta este
prima mea pagina in html si Iar acesta este primul meu text formatat
ingrosat(eng.bold) scris ingrosat .
-deci tot ceea ce scrieti intre tag-urile <b> si </b>
va fi vizualizat ca text ingrosat pe ecranul monitorului

Probleme des intilnite.
-Am incercat sa modific continutul paginii iar dupa ce am facut asta
modificarea nu se vede in browser.Aste se intimpla din cauza ca browser-ul nu
"stie" ca tu ai modificat pagina;ca sa-i "aduci aminte"
apasa pe butonul refresh di bara de butoane.
-Ce browser pot sa folosesc pentru a testa paginile web construite? Ca sa
testezi paginile web construite de tine recomandam cel mai simplu si mai comun
browser Internet Explorer 5.0(sau chiar 6.0).Asta nu inseamna ca nu puteti testa
paginile voastre pe alt browser ca Mozila 1.3 ,Netscape 6.0,Opera 7.0 depinde
de tine cu care esti obisnuit dar trebuie sa stii ca marea majoritate a
surfer-ilor(cei care navigheaza pe web) web folosesc Internet Explorer 6.0. -
Prezentarea

Pagina principala a paginii
web este index.htm, unde gasim cateva informatii despre ceea ce reprezinta
unitatea centrala, hardware-ul, despre pc-uri. In partea din stanga gasim
meniul site-ului, iar in dreapta continutul
paginilor web.

Ultimele doua butoane nu sunt întîlnite la toate carcasele , la carcasele ATX butonul de reset nu mai este prezent în unele cazuri , restartarea revenind în sarcina sitemului de operare si a Bios-ului ; în schimb , butonul de schimbare a frecventei a disparut complet de pe carcasele noi , rolul sau fiind activ în cazul procesoarelor din familia i286 , i386 , i486 .

font color=
"#003366">Memoria RAM</
font> ( Random Access Memory
) este pentru citire si scriere. Pentru citire se determina informatia memorata, iar pentru scriere se memoreaza informatiile .</p> <p> Cu cât memoria interna este mai mare cu atât programele se executa mai repede . Fizic, memoria se
prezinta sub forma unor circuite integrate ( circuite electrice
obtinute prin aplicarea pe un suport electroizolant a elementelor de circuit electric în scopul miniaturizarii si simplificarii tehnologiei de fabricatie ) , lipite pe un circuit imprimat care se ataseaza placii de baza .</p> <p> Memoria este spatiul de lucru primar al oricarui calculator . Lucrând în tandem cu CPU (procesorul) are rolul de a stoca date, de a procesa informatii ce pot fi procesate imediat si în mod direct de catre processor sau alte dispozitive ale sistemului. Memoria este de asemenea legatura dintre software si CPU .</p> <p><font size="2"><br> &

ce fac legatura intre procesor, sistem si monitor. Ea este &
icirc;nzestrata
cu microprocesor propriu numit accelerator grafic si cu memorie proprie
numita memorie video . Au rolul de a afisa pe monitor datele procesate de CPU (de fapt rezultatul acestori procesari). Se conecteaza pe placa de baza printr-un slot ISA, PCI sau AGP. Placile video pot contine acceleratoare 3D care degreveaza procesorul, versiunile profesionale incluzand chiar 2 procesoare 3D pe placa video.<br> Imaginea care apare pe monitor este formata dintr - o serie de suprafete dreptunghiulare numite pixeli . Fiecare pixel reprezinta o anumita
culoare si este atât de mic încât nu poate fi distins . Numarul de pixeli care se afiseaza pe ecran se numeste rezolutie . Aceasta împreuna cu monitorul face parte din ansamblul video al echipamentului de calcul. <p>Reprezinta o componenta importanta a sistemului, viteza sa influentand în mare parte performanta sistemului. În functie de cantitatea de memorie existenta pe placa video rezolutiile la care poate lucra sunt 640x480,800x600,1024x764,etc . Placile video bune ofera si o rata de reimprospatare (de la 85 Hz in sus) a imaginii optima ce reduce riscul aparitiei afectiunilor oculare .</

Capacitate de stocare: 20 Gb & 300 Gb<br> Memoria cache: 2 Mb, 8 Mb</font></p> <p><font color="#003366" size="2">Hard discurile sunt unitati de stocare magnetice. Ele au capacitati variabile de la 40 MB (unitatile foarte vechi, fara sa pomenim de cele & de muzeu& ) si pana la 160 GB, mai nou, un hard disk <a href="https://www.ibm.com">IBM</a>. De fapt, factorul determinant in realizarea unei capacitati cat
mai mare este si factorul de adresare, pe 16 sau 32 de biti, denumit FAT (File Allocation Tables). La FAT 16, capacitatea maxima posibila la un hard disk este de 2,1 GB (solutia & trecerea la FAT 32). O alta piedica, de aceasta data tinand de BIOS, este de 8,4 GB. Aici intervine INT 13 din BIOS, un parametru ce nu permite dimensiuni mai mari de 8,4 GB (solutia & modificarea parametrului sau update de BIOS). La FAT 32, capacitatea maxima este de cativa terabytes, deci indeajuns (si inca destul) de mare.</font></p> <

font color=
"#003366" size=
"2">Un factor determinant in performanta
unui HDD este si viteza de rotatie a platanelor sale. Ea variaza de la 4400 rpm (la unele unitati Quantum, destul de rare) si pana la 15000 de rpm(la unele Hard - Diskuri Maxtor pt. servere).<br> Vitezele uzuale sunt de fapt 5400 si 7200 rpm, mai rar 10000 de
rpm la hard-diskurile Quantum Atlas 10 K II destinate serverelor.<br> Principalii producatori de hard diskuri in ziua de azi sunt Maxtor,
Western Digital, Seagate, Quantum (pana nu demult, pentru ca a fost cumparat de Maxtor), si <a href="https://www.ibm.com">IBM</a> (ultimul fiind Fujitsu, care insa a renuntat acum putin timp la a mai produce hard & diskuri).</font><br> <

este o unitate optica de stocare a datelor. Ea foloseste laserul pentru
a citi mediile CD.
Un CD poate avea capacitatea de 650 sau 700 MB (in format muzical 74 sau 80 de minute). De curand au fost inventate si CD-urile de 800 & 900 MB, si chiar cele de 1,3 GB (Sony). Acestea necesita insa unitati speciale de citire / scriere.<br> Ca tot vorbisem de scriere, unitatile CD-ROM nu pot scrie CD-uri (tocmai de aceea se numesc CD-ROM-uri (Compact Disk & Read Only Memory), pentru ca ele nu pot scrie CD-uri). Rolul
scrierii de CD-uri ii revine unei alte unitati, denumite CD-R/RW (CD-Writer/ReWriter),
care poate atat scrie, cat si citi CD-uri.
Unele CD-Writere mai vechi puteau doar scrie CD-uri , si nu rescrie sau citi.<br> Fiecare CD-ROM/RW are un buffer pentru acces rapid la date. Dupa ce datele sunt citite de pe CD, cele mai des utilizate sunt stocate in buffer, care poate varia (in general este de 128 KB).
La CD-R/RW, bufferul se foloseste si la scriere (mai ales la scriere). El variaza de la 2 MB la chiar 8 MB la unitatile scumpe. In general, unitatile cu buffer de 8 MB sunt cele produse de Plextor/ASUS/Yamaha, cele cu buffer de 4 MB de TEAC/LG si cele cu 2 MB de Sony/Philips/LG/TEAC.<br> In legatura cu vitezele unitatilor CD-ROM/CD-RW, acestea sunt cuprinse
intre 1 si 72! (da, chiar exista o unitate CD-ROM cu 72 de viteze). O viteza este considerata a fi un transfer de 150 KB de date. In ziua de astazi se vand unitati CD-ROM cu viteze cuprinse intre 40 (Philips,TEAC) si 54 de viteze (Artec).<br> Cele mai bune unitati de CD-ROM sunt considerate a fi unitatile de la ASUS (50 X) si TEAC (40 X).<br> Unitatile CD-RW au viteze intre 1 si 32 (mai de curand ASUS a lansat o unitate CD-RW cu 32 de viteze).<br> Toate unitatile de la 16 X in sus au incorporate tehnologia Buffer Underrun Prevention (BURN-Proof) sau o echivalenta(Seamless Link,
Write Proof). Aceasta impiedica golirea bufferului unitatii si, implicit, distrugerea CD-ului de inscriptionat.<br> DVD-urile sunt unitati de mare capacitate, (uzual 4,7 GB), ce sunt construite pentru a stoca filme de lunga durata la o calitate deosebita.Unitatile DVD-ROM, ca si in cazul celor CD-ROM,
pot doar sa citeasca mediile DVD, iar cele DVD-RAM sunt echivalente
omoloagelor lor de la CD-uri, si anume CD-RW-lor.</font></font><font color="#003333"><br> </

ce ne permit accesul la retele de tip WAN (Wide Area Network), in
speta ne permit accesul la internet. Denumirea lor provine de la faptul ca pot trimite faxuri si din cauza ca pentru propagarea semnalului prin mediul de transport folosesc o metoda de MOdulare/DEModulare.<br> Exista mai multe tipuri de modemuri, la care difera in principal
rata de transfer.<br> Astfel, un modem de cablu are o rata de transfer variabila, de la
128 KBit/s pana la 2-4 MBit/s, un modem DSL/SDSL/ADSL (Digital Subscriber Line/Symetric Digital Subscriber Line/Asymetric Digital Subscriber Line) are 2 & 8 MBit/s (download) si 2 & 4 MBit/s (upload),
un modem radio are 3 MBit/s maxim iar un modem dial-up are chiar
si 230 KBit/s rata de transfer maxima (de fapt e in jurul valorii de 56 KBit/s).<br> Rata de transfer maxima la transmiterea de faxuri este de 14400 bps (uzual este 9600 bps).<br> Cei mai importanti producatori de fax modemuri sunt US Robotics
(3Com) si Rockwell/Conexant.</font></p> <p><font color="#006666"><br> <
