Differentiate between circuit switching and packet switching.
ReplyDeleteCircuit switching is a single-connection method whereby it is centrally controlled. Whereas packet switching travels from computer to computer along the network by breaking down into packets and labeled electronically with codes for their origin and destination.
Circuit switching is vulnerable to destruction of signal control point or any link in the single path that carries the signal. Whereas packet switching is more reliable as it uses multiple routers instead of central control point to determine the best way for a packet to move towards its destination. Therefore, if parts of the network is not operating, each router can send individual packets along different paths.

What is HTML?
HTML, an acronym for HyperText Markup Language, is the predominant markup language for web pages. It provides a means to describe the structure of text-based information in a document—by denoting certain text as links, headings, paragraphs, lists, etc.—and to supplement that text with interactive forms, embedded images, and other objects. HTML is written in the form of "tags" that are surrounded by angle brackets. HTML can also describe, to some degree, the appearance and semantics of a document, and can include embedded scripting language code (such as JavaScript) that can affect the behavior of Web browsers and other HTML processors.
What is the diference between Circuit Switching and a Packet switching?

what iModem (from modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used over any means of transmitting analog signals, from driven diodes to radio.

Bandwidth is the amount of data transmitted along a particular communication channel, such as by radio (eg. WiFi) and cable (eg. fibre optic cable).
Bandwidth is measured in the number of bits transmitted per second, or bps *note: lower case "b"*
Depending on context, "bandwidth" can refer to the theoretical maximum transfer rate, or the actual rate that data is being transferred.
For example, the theoretical maximum transfer rate for a 802.11g WLAN connection is Mbps (Mega bits per second) while the actual transfer rate can be somewhere between 25-50% of that, depending on signal quality and the hardware used.

Question 8:
Differentiate between intranet and extranet?
An intranet is an information portal designed specifically for the internal communications of small, medium or large businesses, enterprises, governments, industries or financial institutions of any size or complexity. Intranets can be custom-designed to fit the exact needs of businesses no matter where they are situated. Users of intranets consists mainly of:
(1) Members of the executive team.
(2) Accounting and order billing.
(3) Managers and directors.
(4) Sales people and support staff.
(5) Customer service, help desk, etc..
An extranet is somewhat very similar to an intranet. Extranets are designed specifically to give external, limited access to certain files of your computer systems to:
(1)Certain large or priviledged customers.
(2)Selected industry partners.
(3)Suppliers and subcontractors... etc.
Therefore, a carefully designed extranet can bring additional business to companies. Intranets and extranets all have three things in common:
1:They both use secured Internet access to the outside world.
2:Both can drastically save your company or organization a lot of money.
3:Both need a user ID & password to control access to the whole system.
2.What are the FOUR key points of open architecture philosophy?

4.Describe the THREE main types of cable used to connect computers to a network.
ReplyDeleteThe three main types of cable used to connect computers to a network are:
(i) Twisted-pair cable. It is the earliest telephone and telegraph line or open wire single-wired earth return circuit. It had been used to transmit voice signal for years by telephone companies. The con is it will generate electric interference. This happens when it carries small flow of unwanted electricity in nearby objects, including other wires, created when a wire carries an electric current and generates an electromagnet field around itself. One example of twisted-pair cable is Category 1 cable which had been used by telephone companies for years to transmit voice signal.
(ii) Coaxial cable. Coaxial cable is mainly used as a transmission line for radio frequency signals, in application such as connecting radio transmitter and receiver with their antennas, computer network (internet) connection, and distributing cable television signal. It is able to carry signal 20 times faster than category 1 cable but more expensive. Unlike twisted-pair cable, electromagnetic interference only occurs only in the space between the inner and outer conductors of coaxial cable. There are 2 types of coaxial cable, the first one is Category 5 cable. It can carry signal between 10 to 100 times faster than coaxial cable and it is easy to install. The second type is Category 5e cable, which is constructed of higher quality materials than Category 5 and carries more signals up to 10 times faster than regular Category 5 cable.
(iii)Fiber optic cable. It is the most expensive type of cable; transmit pulsing beams of light through very thin of strands of glass. The speed of signal transmission is the fastest among the rest. It permits transmission over a longer distance and at higher bandwidths (date rates) than other forms of communication. Unlike Twisted-pair and coaxial cable, fiber-optic is immune to electromagnetic and electrical interference; there is no cross-talk between signals in different cables and no pickup of environmental noise.

2. What are the FOUR categories of Internet uses? Name some of the examples from these categories.
ReplyDeleteThe first category of internet uses is new ways to communicate. For instance, e-mail. I think e-mail is like the substitute for the letter because letter is send through by postman and it takes at least 3 days to send to the receiver; while e-mail is send via internet and it just take a few second to send. The following example is electronic discussions such as windows live messenger, ebuddy, meebo and so forth. Then, instant messaging is like SMS.
Second category of internet uses is information resources and software. The examples are newspapers and magazines (people can read the recently news or even old news by exploring the internet), government documents, research reports and books (students can do their online research for their own purpose), and software download sites (people can even download software such as antivirus software, photoshop software, or songs, movies, and games).
Third category of internet uses is doing business online. For example, electronic storefronts, coordinate worldwide operations (businessman even can online meeting with their customer or staff if they are in another country), and recruit employees (nowadays, many companies try to online to recruit new employer).
Fourth category of internet uses is entertainment. We can uses internet to review restaurants, movies, theater, musical events and books. For instance, people can review what movies they want to watch, at which theater, when, and then straight away book their ticket. Moreover, people also can share or play interactive games with their friend. Follow sports teams is another example under this category.
Lastly, all of us are using internet to do our tutorial question, quiz or even download our lecturer notes from internet.

Question 15: Explain what modem is.
ReplyDeleteA modem is the derived short form name for modulator-demodulator. Its main purpose is to convert digital signals of 1 and 0s to analog signals or tones, so that it could be transferred as specific frequencies through cables and lines such as the telephone or television cable lines, to the intended receiver or device. The process of converting the digital signal of the sending device to analog signal is called modulation, and the process of converting the analog signal to back to digital signal is called demodulation, hence the word, ‘Modem’.
From the earliest modem device capable of sending 300bps (bits per second) or baud (different than bits per second, rather it is symbols per second), its transmission speed soon grew as a result of rapid technology developments and needs, and as of today we have various types of modems available for different needs, access and usage, such as the Asymmetric Digital Subscriber Line (ADSL) modem, the Symmetric Digital Subscriber Line (SDSL) modem, cable modem and even a satellite modem, where the SDSL modem is mostly used for business corporations. Cable modems are mostly used for television devices to access to the Internet, provided by cable TV provider and the lesser-known satellite modem, that converts digital signals to radio waves to communicate with satellite dishes.
The most common modem used in most households is the ADSL modem, which if you subscribe to Streamyx for your Internet connection in Malaysia, the blue colored ADSL modem device will be included in the Internet subscription package. ADSL modem’s advantages is its faster downloading speed rather than uploading speed, which is in the interest of most casual computerists’ needs, as well as faster than the original dial-up modem. It also allows the usage of the telephone line simultaneously with the usage of the Internet connection, something that the dial-modem is not capable of.

Question 11.
Differentiate between IPv4 and IPv6.
IPv4 is the current system used for addressing on the Internet. It consists of four written 8-bit parts; 32bits. For example it is expressed as; 255.8.24.199 The IPv4 addresses has 4 billion different combinations but it is becoming much more limited in the near future. In terms of mobility, IPv4 uses Mobile IPv4.
IPv6 is the new protocol set up to replace IPv4. It consists of 128 bits and is expressed in a hex-decimal form as opposed to IPv4 which is expressed in a decimal form. For instance, a hex-decimal is shown as; 2001:db8:0:d802:2d0:b7ff:fe88:eb8a
IPv6 has about 70 octillion different combinations and has better improved security and network related features. It also has better bandwidth efficiency. Mobile IPv6 provides fast handovers, better router optimization and hierarchical mobility. Hence, it provides better efficiency and scalability in terms of working with the latest 3G mobile technologies.

5. Differentiate between circuit switching and packet switching.
Circuit switching is centrally controlled and has a single connection method. It is used by most of the local telephone traffic today.
Packet switching is when files are broken down into packets and labeled electronically with codes for their origin and destination. These packets travel along the network from computer to computer until they reach their destination. Routers determine the best way for a packet to move to its destination, this best way is determined by the use of routing algorithms.
Packet switching is more reliable than circuit switching as packet switching rely on multiple routers instead of one central point of control. Thus, each router can send individual packets along different paths if parts of the network are not operating. This is in contrast to circuit switching, where the signal control point or link in the single path that carries the signal is vulnerable to destruction. Once it is destroyed, the files and messages can no longer reach its destination.

ReplyDelete"what is the internet and how internet relates to the world wide web?
ReplyDeleteInternet is a large collection of computers all over the world connected to one another. By Internet users be able to share information along. The computer (host) that connects to the Internet is able to access information from an enormous array of available server and also other computer by moving the information to the local’s memory. Internet is decentralized by design and each Internet computer is independent. Its operator can choose which Internet services to use and which local service to make available to the global Internet community.
How Internet relate to World Wide Web (www)? The Internet and The Web are two separate but related things. Web is a way to accessing information through the medium of the Internet. It is an information-sharing model that is built on top of the Internet.
The web is just the ways to spread the information over the Internet, and Internet is the massive network of network, network infrastructure that connects a millions of computers together globally.

ReplyDeleteWhat are the FOUR categories of Internet uses? Name some of the examples from these categories.
ReplyDeleteAnswer:
There are four categories of Internet uses:
1) Communication via e-mail, instant messaging, and e-discussion. The examples for these are Yahoo! Messenger, MSN Messenger, Skype, Yahoo! Groups, Blogger.com, etc.
2) Info resources and Software. Via these uses, a surfer can surf and get information they need for example via Star Online and NST Online for news, MYeG for e-government services, and CNet and Download.com for software dowloads.
3) E-Bay and Mudah.com.my, however, can be used for businesses online, meanwhile Jobstreet.com, JobsDB and graduan.com.my are used widely for recruitments and graduates' advice resources.
4) Last but not least, the Internet is also used for entertainment purposes. ESPN.com are clicked for sports match scores, TGV, GSC and Fandango are surfed to see the movie times and synopsis. McD, Pizza Hut, and Yellow Cab are for restaurants and dining menus.

1.What is the Internet, and how the World Wide Web relates to the Internet?
ReplyDeleteInternet is a worldwide connection with one another, it is also the most amazing technological developments of the 20th century. Futhermore, internet is one of a new way for people to communicate with each other such as email, electronic discussions and instant messaging. Internet as replaces the tradition way of searching for information resources. People can even read newspaper & magazines through online, and search for Government documents and research reports and books. Nowadays, people not only can do business a certain place, they can actually also own a business overseas even if they r not there. For people who do not like to go out of the house, they can actually shop through online to get the things they want and many others activities, such as playing games.
The World Wide Web helps people who are not computer expert to manage the task.

Q4.Describe the THREE main types of cable used to connect computers to a network.
ReplyDelete1. Twisted-pair cable: it is the oldest type of cable and it is commonly used by telephone campanies.one of the example of this cable is Category 1 cable. This cable is a twisted-pair cable that telephone companies have used for years to transmit voice signals.
2. Coaxial cable: this cable is 20 times faster than Category 1 cable and of course it is more expensive compare to twisted-pair cable. Then, there are two types of coaxial cable- Category 5 cable and Category 5e cable. Category 5 cable carries signals between 10 and 100 times faster than coaxial cable and it is easy to install. While Category 5e cable constructed of higher quality materials than Category 5 cable and it carries more signals up to 10 times faster than regular Category 5 cable.
3. Fiber-optic cable: this is the most expensive type of cable and it transmits pulsing beams of light through very thin strands of glass. so it has the fastest transmission rate.

QUESTION 15,EXPLAIN WHAT IS MODEM?
Modem (from modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used over any means of transmitting analog signals, from driven diodes to radio.

Differentiate between circuit switching and packet switching.
ReplyDeleteCircuit switching is a centrally controlled, single-connection method to detruction of the signal control point or any link in the single path that carries the signal, eg. it is commonly used by most local telephone traffic nowadays.
Packet-switching transfer files and messages by broken down into packets and labeled electronically with codes for their origin and destination. These packets from computer to computer along the network until they reach their destination, moreover, the routers detemine the best way for a packet to move towards its destination. It is more rely on multiple routers instead of central point of control. Besides, each router can send individual packets along different paths if parts of the network are not operating.

5. Can a printer be defined as a client when connected to a network?
- No, a printer cannot be defined as a node since it can’t be operated as a computer
6. Describe the THREE main types of cable used to connect computers to a network.
ReplyDelete- Twisted-pair cable (as the name suggest these are a number of cables in pair mostly 2 pairs “4 wires” twisted together to reduce the effect of electrical interference/electromagnetic induction around it, these are the oldest type of cable, used by telephone companies)
- Coaxial cable (it is made up of one thick middle wire and a mesh of wire net around it separated by an insulator, it is 20 times faster than category 1 cable and expensive)
- Fiber-optic cable (most expensive type of cable, transmits pulsing beams of light through very thin strands of glass, faster than transmission rate since the pulse travels at a speed of light)
7. Mention all the 6 types of cables
- Twisted-pair cables
- Category 1 cable
- Coaxial cable
- Category 5 cable
- Category 5e cable
- Fiber-optic cable
8. Define circuit switching and packet switching.
- Circuit switching: it’s a single connecting method which is centrally controlled and used by most local telephone traffic
- Packet-switching: it’s the breakdown of data into pieces know as packets at the same time labeling them electronically with codes of their origin and destination
9. Differentiate a) circuit switching with b)packet switching
- Centrally controlled
- Used by most local telephone traffic
- Single connection method
- Vulnerable to destruction of signal since its a single path
- b- files and messages are broken down into packets and labeled with origin and destination data
- b- packets travel along computer to computer until they reach their destination
- b- routers determine the best way for a packet to move towards its destination
- b- rely on multiple routers instead of central point of control
- b-in case of a break down in a device/router, each router can send packets along different paths if parts of the network are not operating
10. What are packets?
- These are messages/data broken down into pieces known as packets, each carrying the IP number of the origin and destination including the number of packets being transferred
1. What do you understand by the term router?
ReplyDelete- A router is a device that connects two or more logical subnets
2. List the usage of a router
- It’s used to break the network into smaller more efficient subnets to prevent excessive rates of Ethernet packet collision in a large network
- They determine the best way for a packet to move towards its destination
3. Define a subnet/subnetwork
- A subnet describes networked computers and devices that have a common designated IP address routing prefix
4. Routing algorithms?
- These are programs that enables a router to determine the best path for packets
5. Definitions
- DOD : Department of Defense
- DARPA: Defense Advanced Research Projects Agency
- NCP: Network Control Protocol
- TCP/IP Transmission Control Protocol/Internet Protocol
6. What are the FOUR key points of open architecture philosophy?
- Independent networks should not require any internal changes to be connected to the Internet
- Packets that do not arrive at their destinations must be retransmitted from their source network
- The router computers do not retain information about the packets they handle
- No global control will exist over the network
7. Explain what is TCP/IP.
- TCP: these are a set of rules used by computers during transmission on a network to establish and break connection
IP: a set of rules used for routing of individual data packets
