Answer: WIREFRAME
A website wireframe, also known as a page schematic or screen blueprint, is a visual guide that represents the skeletal framework of a website.[1]:166 Wireframes are created for the purpose of arranging elements to best accomplish a particular purpose. The purpose is usually being informed by a business objective and a creative idea. The wireframe depicts the page layout or arrangement of the website's content, including interface elements and navigational systems, and how they work together.[2]:131 The wireframe usually lacks typographic style, color, or graphics, since the main focus lies in functionality, behavior, and priority of content.[1]:167 In other words, it focuses on what a screen does, not what it looks like.[1]:168 Wireframes can be pencil drawings or sketches on a whiteboard, or they can be produced by means of a broad array of free or commercial software applications. Wireframes are generally created by business analysts, user experience designers, developers, visual designers, and by those with expertise in interaction design, information architecture and user research.
Answer:
(b) Windows is an open source operating system (<em>This is not correct</em>)
Explanation:
Option a is <em>correct</em> because Xerox PARC(Palo Alto Research Center), which is a subsidiary of the Xerox corporation, has been greatly responsible for invention and development in modern computing devices. Some of these developments are in Ethernet and graphical user interface (making use of menus, icons e.t.c).
Option b is <em>not correct</em> because Windows Operating system is not an open source operating system. Open source OS means users can interact with the driving code of the OS and make modifications. Windows does not support this feature. Operating systems that are open source include Linux and OpenSolaris.
Option c is <em>correct</em>. An operating system has two main components - the kernel and the user interface. The core component of an operating system is the Kernel as it interacts directly with the hardware and manages system resources. The user interface on the other hand allows users to interact with the kernel of the operating system using texts and/or graphics as commands.
Option d is <em>correct</em>. Linux operating system is an open source OS. Therefore, the source code is made available to the public for examination and modification.
Explanation:
We can divide the multiplex in different categorize, for example:
- FREQUENCY DIVISION MULTIPLEXERS (FDM)
-
TIME DIVISION MULTIPLEXERS (TDM)
-
STATISTICAL TIME DIVISION MULTIPLEXERS (STDM).
But in this case, we're going to explain about the time and frequency, because the time division multiplex differ to frequency, because the circuit is divided horizontally, and the time is vertically
b. splits the communication circuit vertically (with time slots) instead of horizontally
Answer:
Information about the parts of a cell, its location and role will help describe the appearance of a cell's content.
Organelles are cell structures that include the nucleus, cytoplasm, cell membrane among others. One can view these using a light microscope.
1. Cell Membrane is a fluid mosaic. It is the outer boundary of the cell.
2.Cytoplasm is the fluid inside the cell. It is located between the nucleus and the cell membrane.
3.Nucleus is the control center of the cell and is located at the center.
Answer:
identify materials to create a prototype
