Waa maxay shabakad kombuyuutar? Taasi maaha su'aal aad si joogto ah u maqashid, laakiin waa muhiim, si kastaba ha ahaatee. Shabakado kambuyuutar la'aanteed, intarneedku uma fiicnaan doono sida uu maanta yahay, markaa anagoo taas maskaxda ku hayna, waxaan go'aansanay inaan sharaxno waxa shabakadu tahay, kuwa bilawga ah, oo ay la socdaan noocyada kala duwan ee shabakadaha. Ma aha oo kaliya, laakiin maqaalkani wuxuu ka hadli doonaa faa'iidooyinka shabakad. Ma jiraan wax khasaare ah oo dhab ah, sidaas darteed, xitaa ma aadi doono halkaas.

Waa maxay Shabakadda Kombiyuutarka

Hagaag, shabakadu waa koox ka mid ah nidaamyada kombiyuutarada oo ku xidhan si ay u wadaagaan agabka iyo xidhiidhka. Intaa waxaa dheer, shabakadu sidoo kale waa ururinta aaladaha iyo kombuyuutarrada si wadajir ah ugu xiran warbaahinta gudbinta iyo qalabka isgaarsiinta.

Waxaan uga hadli doonaa wax badan oo ku saabsan war-baahinta maqaal kale, markaa isha ku hay taas dhawaan.

Utility network

1. Dedeji isgaarsiinta
2. La wadaag qalabka ku xidhan
3. Qaybi xogta iyo macluumaadka

1] In la dedejiyo isgaarsiinta

Shabakadaha awgood, dadku waxay si sahal ah ugu wada xidhiidhi karaan iimaylka, aaladaha fariinta, chatrooms, warbaahinta bulshada, mareegaha sida kan, wicitaanka fiidyaha ee khadka, iyo wax ka badan. Haddii shabakadu hoos u dhacdo, markaa dhammaan qalabka ku xiran ma shaqeyn doono.

2] La wadaag qalabka ku xiran

Haddii ay jiraan qalabyo hardware gaar ah oo ku xidhan shabakad, markaas waxa aad u fudud in qalabkaas lala wadaago dhammaan kuwa gelaya shabakadda. Tusaale ahaan, faylasha xogta ama daabacaha ayaa aad ugu badan shabakadaha, waxaana loo yaqaan ilaha shabakadda.

3] U qaybi xogta iyo macluumaadka

Waar arrintu; Haddii aad tahay isticmaale idman, markaa waa inaadan wax dhibaato ah kala kulmin helitaanka xogta iyo macluumaadka lagu kaydiyay shabakadda. Shirkad ay ka mid tahay Microsoft waxay lahaan doontaa kayd weyn oo macluumaadka macaamiisha iyo waxyaabo kale, waxaanan oo dhan waxay u furan yihiin shaqaalaha leh awoodda saxda ah.

Noocyada shabakadaha kombiyuutarka

1. Shabakadda Aagga Maxaliga ah (LAN)
2. Wireless LAN (WLAN)
3. Shabakadda Aagga Weyn (WAN)
4. Shabakadda Aagga Magaalo Weynta (MAN)
5. Shabakadda Aagga Shakhsi ahaaneed (PAN)
6. Shabakadda Aagga Campus (CAN)
7. Shabakadda Aagga Kaydinta (SAN)

1] Shabakadda Aagga Maxalliga ah (LAN)

Waxa aan halkan ku haynaa waa shabakad isku xidha kombuyuutarrada iyo aaladaha ku yaal meel yar oo juqraafi ah. Tusaale ahaan, LAN wuxuu inta badan ku yaalaa dhismo. Dhab ahaantii, dhismuhu wuxuu yeelan karaa shabakado badan oo deegaanka ah oo^{(Local Area Networks)} isku xidhan.

2] Wireless LAN (WLAN)

Sida magacaba ka muuqata, shabakada noocani waa 100 boqolkiiba bilaa-waayirka. Waxay ku tiirsan tahay router ku xiran internetka, kaas oo isna, bixiya isku xirka wireless qalab kasta oo la taageeray. Shabakaddan hadda waxay ku taal gurigaaga.

3] Shabakadda Aagga Magaalo Weyn (MAN)

OK, marka ninku^(MAN) wuxuu ku saabsan yahay isku xirka Shabakadaha Deegaanka^{(Area Networks)} ee aagga magaalo weyn. Fogaanta awgeed^(Due) , isku xirka shabakadahan si loo abuuro MAN waxaa lagu sameeyaa tignoolajiyada gudbinta, kuwaas oo ay jiraan dhowr. Coaxial iyo fiber ayaa laga yaabaa inay yihiin kuwa ugu badan ee loo isticmaalo wax kasta oo kale sababtoo ah kharashka.

4] Shabakadda Aagga Weyn (WAN)

Sida aan u sheegi karno, WAN waxay la mid tahay MAN , iyada oo farqiga u yahay fogaanta. Shabakadda Aagga ballaadhan^{(Wide Area Network)} , juqraafi ahaan kala sooc LAN^(LANs) -yada ama WAN^(WANs) -yada ama waxay ku wada xidhan yihiin tignoolajiyada wireless-ka, satalaytka inta badan.

5] Shabakadda Aagga Gaarka ah (PAN)

Magaca oo keliya, waa inaad fikrad ka heshaa waxa shabakadani ka kooban tahay. Waa shabakad adeegsata fiilooyinka iyo tignoolajiyada wirelesska si ay ugu xidhaan kombayutarada iyo aaladaha goobta shaqada ee gaarka ah.

Akhriso^(Read) : Waa maxay nidaamyada shabakadaha NTP iyo SNMP^{(NTP and SNMP network protocols)} .

6] Shabakadda Aagga Campus (CAN)

Caadi ahaan waxaa laga helaa jaamacado ama shirkad kasta oo leh xarun xarun u eg. Shabakadda waxaa suurtageliyay taxanayaal LAN^(LANs) ah oo ka yimid dhismayaal u dhow. Way ka weyn tahay LAN-ga^(LAN) caadiga ah , laakiin isla markaa, way ka yar tahay nin^(MAN) .

7] Shabakadda Aagga Kaydinta (SAN)

Midkani aad buu u fudud yahay. Aaladaha kaydinta ayaa si wada jir ah ugu xiran iyadoo la isticmaalayo isku xirka xawaaraha sareeyo.

Waxaan rajaynaynaa casharkan aasaasiga ah inuu kaa caawiyo inaad fikrad hesho.^{(We hope this basic tutorial helps you get an idea.)}

What is a Computer Network? Different types of Computer Networks

What is а computer network? That’ѕ not a question you hear on a regular basis, but it is important, nonetheless. Without computer networks, the internet woυldn’t be as efficient as it is today, so with that in mind, we’νe decided to explain what a netwоrk is, to beginners, along with different types of networks. Not only that, but this article will discuss the advantages of a network. There are no real disadvantages, therefore, we won’t even go there.

What is a Computer Network

Well, a network is a group of computer systems connected to share resources and communicate. Additionally, a network is also a collection of devices and computers linked together via transmission media and communication devices.

We will talk more about transmission media in another article, so keep an eye out for that very soon.

Utility of a network

1. Expedite communications
2. Share connected hardware
3. Distribute data and information

1] Expedite communications

Because of networks, people can easily communicate with each other via email, messenger tools, chatrooms, social media, websites such as this one, online video call, and much more. If a network goes down, then all the tools connected to it will no longer operate.

2] Share connected hardware

If there are certain hardware devices connected to a network, then it becomes quite easy for those devices to be shared with all who have access to the network. For example, database files or a printer are quite common on networks, and they are known as the network’s resources.

3] Distribute data and information

Here’s the thing; if you are an authorized user, then you should have no problems gaining access to data and information stored on the network. A company such as Microsoft would have a huge database of customer information among other things, and all of this is open to employees with the right authority.

Types of computer networks

1. Local Area Network (LAN)
2. Wireless LAN (WLAN)
3. Wide Area Network (WAN)
4. Metropolitan Area Network (MAN)
5. Personal Area Network (PAN)
6. Campus Area Network (CAN)
7. Storage Area Network (SAN)

1] Local Area Network (LAN)

What we have here is a network that connects computers and devices in a small geographical area. For example, a LAN is usually located in a building. In fact, a building can have multiple Local Area Networks connected to each other.

2] Wireless LAN (WLAN)

As the name suggests, this type of network is 100 percent wireless. It relies on a router that is connected to the internet, which in turn, provides wireless connectivity to any supported devices. This network is currently in your home.

3] Metropolitan Area Network (MAN)

OK, so a MAN is all about connecting Local Area Networks in a metropolitan area. Due to the distance, connecting these networks to create a MAN is done via transmission technology, of which there are several. Coaxial and fiber are probably the most used over anything else due to cost.

4] Wide Area Network (WAN)

From what we can tell, a WAN is similar to a MAN, with the difference being the distance. In a Wide Area Network, geographically separate LANs or WANs or connected together via wireless technology, a satellite in most cases.

5] Personal Area Network (PAN)

From the name alone, you should get an idea of what this network entails. It’s a network that uses wires and wireless technology to connect computers and devices in an individual workspace.

Read: What are NTP and SNMP network protocols.

6] Campus Area Network (CAN)

Usually found in universities or any company with a campus-like headquarters. The network is made possible by a series of LANs from nearby buildings. It’s larger than a regular LAN, but at the same time, smaller than a MAN.

7] Storage Area Network (SAN)

This one is super simple. Storage devices are connected together using high-speed connections.

We hope this basic tutorial helps you get an idea.
