(ii) Mobile Internet connections provide good speeds and allow you to access the Internet.
2. DSL:
(i) DSL, which stands for Digital Subscriber Line, uses existing 2-wire copper telephone line connected to one's home so service is delivered at the same time as landline telephone service.
(ii) Customers can still place calls while surfing the Internet.
3. Satellite:
(i) In certain areas where broadband connection is not yet offered, a satellite Internet option may be available
(ii) Similar to wireless access, satellite connection utilizes a modem.
4. Cable:
(i) Cable Internet connection is a form of broadband access.
(ii) Through use of a cable modem, users can access the Internet over cable TV lines.
(iii) Cable modems can provide extremely fast access to the Internet.
5. Wireless:

Wired Technology: Wired technology is more associated with wired communication. Wired technology refers to the transmission of data over a wired based communication technology.
Types of bounded media in the data transmission:
1. Twisted pair Cable:
(i) A twisted pair consists of two conductors (normally copper), each with its own plastic insulation, twisted together.
(ii) One of these wires is used to carry signals to the receiver, and the other is used only as ground reference. In addition to the signal sent by the sender on one of the wires, interference (noise) and crosstalk may affect both wires and create unwanted signals.
(iii) Twisted Pair is of two types:
(a) Unshielded Twisted Pair (UTP)
(b) Shielded Twisted Pair (STP)
2. Fibre Optical Cable:
(i) A fibre-optical cable is made of glass or plastic and transmits signals in the form of light.
(ii) In fibre optical cable, light moves only in one direction.
(iii) For two-way communication to take place a second communication must be made between the two devices.
(iv) Optical fibres use reflection to guide light through a channel. A glass or plastic core is surrounded by a cladding of less dense glass or plastic.
(v) The difference in density of the two materials must be such that a beam of light moving through the core is reflected off the cladding instead of being refracted into it.
3. Coaxial Cable:
(i) Coaxial is called by this name because it contains two conductors that are parallel to each other.
(ii) Copper is used in this as a central conductor. It is surrounded by PVCinstallation.
(iii) Outer metallic wrapping is used as a shield against noise and as a second conductor which completes the circuit.
(iv) The outer conductor is also encased inan insulating sheath.
(v) The outermost partis the plastic cover which protects the whole cable.
(vi) Anything and everything you see around yourself having wires and uses electricity to operate belongs to wired technology.

Memory Management:
(i) Memory Management is the process of controlling and coordinating computer's main memory and assigning memory block (space) to various running programs to optimize overall computer performance.
(ii) The Memory management involves the allocation of specific memory blocks to individual programs based on user demands. At the application level, memory management ensures the availability of adequate memory for each running program at all times.
(iii) The objective of Memory Management process is to improve both the utilization of the CPU and the speed of the computer's response to its users via main memory. For these reasons, the computers must keep several programs in main memory that associates with many different Memory Management schemes.
(iv) The Operating System is responsible for the following activities in connection with memory management.
(v) Keeping track of which portion of memory are currently being used and who is using them.
(vi) Determining which processes (or parts of processes) and data to move in and out of memory.
(vii) Allocation and de-allocation of memory blocks as needed by the program in main memory. (Garbage Collection).
