Computer presentation
Computers have evolved over five generations from vacuum tubes to integrated circuits. The first generation used vacuum tubes and were large, power-hungry machines programmed in machine language. The second generation introduced transistors, core memory, and operating systems. The third generation saw the development of integrated circuits, lowering power consumption. The fourth generation used LSI and VLSI technologies for portable computers, RAID storage, and data communication. The fifth generation utilizes parallel processing, superconductors, speech recognition, robots, and artificial intelligence. Future computers promise even faster, smarter, and more affordable technologies.
Succession “Losers”: What Happens to Executives Passed Over for the CEO Job?
Succession “Losers”: What Happens to Executives Passed Over for the CEO Job? Stanford GSB Corporate Governance Research Initiative
This document summarizes a study of CEO succession events among the largest 100 U.S. corporations between 2005-2015. The study analyzed executives who were passed over for the CEO role ("succession losers") and their subsequent careers. It found that 74% of passed over executives left their companies, with 30% eventually becoming CEOs elsewhere. However, companies led by succession losers saw average stock price declines of 13% over 3 years, compared to gains for companies whose CEO selections remained unchanged. The findings suggest that boards generally identify the most qualified CEO candidates, though differences between internal and external hires complicate comparisons.Viewers also liked (8)

Have you experienced seeing little pop-up windows in your PC or mobile devices? Well, these tell you that software updates are available for your computer, laptop, tablet, or mobile device. Software updates are important to your digital safety and cyber security. Do not click on that “Remind me later” button or at least don’t put off updating your software for long. This will make you feel confident your device is more secure until the next update reminder.

Motherboard
The motherboard is the main circuit board that connects and allows communication between all the components of a computer. It holds crucial parts like the CPU, memory, and connectors for input/output devices. The motherboard functions as the base for all other computer parts and its design depends on the type of CPU installed. It contains important components like the processor socket, power connectors, memory slots, expansion slots, BIOS, and connectors for storage devices, ports, and front panel components to allow the computer to function.

Floppy disk working mechanism
Floppy disks work in a similar manner to cassette tapes and the magnetic strip on a credit card.
The floppy disk is constructed of stur plastic that is embedded with a thin iron oxide coating on
both sides. The head of the floppy disk drive easily manipulates the magnetic coating on the disk
to store information. Information is recorded on circular tracks and triangular sections. A special
head in the drive erases the area to be written before recording occurs. This head is wider than
the head used for recording and reading information to ensure recorded information is not
contaminated from previous information recorded nearby.
When reading the disk, the head moves to the appropriate track and sector quickly without
touching the disk. This is an improvement over older cassette tape storage that required a rewind
or fast forward movement to retrieve information. Floppy disks contain a safety slide on the side
of the case. If the slide is moved to create an opening, the drive will not record on the disk.
Introduction
A peripheral is a piece of computer hardware that is added to a computer in order to expand its
abilities. The term peripheral is used to describe those devices that are optional in nature, as
opposed to hardware that is either demanded or always required in principle. There are all
different kinds of peripherals you can add your computer. The main disctinction among
peripherals is the way they are connected to your computer. They can be connected internally or
externally.
Buses
A bus is a subsystem that transfers data between computer components inside a computer or
between computers. Unlike a point-to-point connection, a bus can logically connect several
peripherals over the same set of wires. Each bus defines its set of connectors to physically plug
devices, cards or cables together. There are two types of buses: internal and external. Internal
buses are connections to various internal components. External buses are connections to various
external components. There are different kinds of slots that internal and external devices can
connect to.
Internal
Types of Slots
There are many different kinds of internal buses, but only a handful of popular ones. Different
computers come with different kinds and number of slots. It is important to know what kind and
number of slots you have on your computer before you go out and by a card that matches up to a
slot you don’t have.
PCI
PCI (Peripheral Component Interconnect) is common in modern PCs. This kind of bus is being
succeeded by PCI.

The CPU processes digital information and communicates with other components via the motherboard. The motherboard connects all the parts including the CPU, memory, storage devices, ports and expansion cards. It communicates with these via the BIOS which allows the hardware components to communicate. The power supply converts mains power to a form suitable to run the computer components, while fans and heatsinks keep components from overheating.
parts of motherboard.pptx
The motherboard is the main circuit board in an electronic device that contains sockets for additional boards. It holds the CPU, memory slots, and has controllers for connecting the power supply, hard drive, optical drives, and other components. Newer motherboards use serial connections like SATA while older ones use IDE, and they provide expansion slots for graphics cards and peripherals using standards like PCIe, PCI, and AGP.
Internal System Unit Components
The three main components of an internal computer system unit are the processor, motherboard, and power supply. The processor acts as the computer's brain and carries out instructions. The motherboard brings all the components together and contains ports for adding peripherals. The power supply converts main power to lower voltages needed to run the computer safely.
PC techniques software and Hardware
