Touch is the computer as some external infrastructure that can be touched. The external infrastructure in a computer that can be touched and seen can be considered hardware. More simply, the various parts of a computer, such as the input, output, and central processing units, are collectively called hardware or mechanical equipment.

A computer system’s physical components are referred to as computer hardware equipment.

The following are the primary categories of computer hardware:

• Central Processing Unit (CPU):

Also referred to as the “brain” of the computer, the CPU is in charge of carrying out commands and analyzing data.

• Motherboard:

The central processing unit, memory, storage, and other critical parts are located on this main circuit board of the computer. It makes these parts connected to one another.

• Memory (RAM):

 During program execution, the CPU needs to access data and instructions fast. Random Access Memory (RAM) stores these items.

• Devices for Storage:

A hard disk drive (HDD) :uses rotating magnetic disks to store data for an extended period of time.

Solid State Drive (SSD): Compared to HDDs, SSDs use flash memory to provide faster data access and greater durability.

External Drives: For portable storage, consider SSDs, external HDDs, and USB flash drives.

Optical drives: For reading and writing optical discs, there are CD/DVD drives and Blu-ray drives.

Devices for Input:

Keyboard: Enables users to provide commands and text to the computer.

Mouse: Allows users to interact with graphical user interfaces and control the cursor on the screen.

Touchscreen: A touch-sensitive display that allows users to interact directly with the image.

Trackpad: Located on laptops, this device enables finger gestures to control the cursor.

Scanner: Creates digital versions of hard copy documents and photos.

Microphone: Recording, speaking, and recording audio input for voice commands.

• Devices for Output:

Monitor: Shows the computer’s visual output.

Printer: Prints digital documents and images into hard copies.

Speakers: The computer’s audio output.

Headphones/Earphones: Give the user access to private audio output.

• Hardware for Networking:

Router: A router is a device that joins devices in a network and gives them access to the internet.

Switch: Controls the direction of data packets on a local area network (LAN) between devices.

Network Interface Card (NIC): Enables wired or wireless network connectivity for computers.

Modem: Transforms digital data from the computer into a format that can be sent over communication lines.

• Peripherals:

Webcam: Allows for video conferencing, recording, and capture of images.

Joystick/Gamepad: Gaming input devices.

Graphics Tablet: Enables handwritten text and drawings to be entered into computers by users.

The main categories of computer hardware equipment are listed here, and each one has a specific purpose inside a computer system.

Some of the aspects that need to be taken into consideration for selecting computer hardware for a library are discussed below:

1. Determine Application area: Before purchasing a computer system, one can proceed to purchase a computer system by carefully considering what the computer is, why it is needed, in which case or how it can be used. According to the work will see its equality.
2. Identify the most feasible application: Whether it will be profitable to use the computer? Will there be any obstacles when this new approach is introduced? How much can be financially beneficial? How useful this method will be to the users and the advantages or disadvantages should be checked. That is, the possibility should be checked.
3. Determine user requirements: The needs of the users should be well identified beforehand. Then they must be seriously judged and analyzed. Opinion survey should be done to know user needs. Their needs should be specified and the work should proceed.
4. System Design: System charts should be created to attain the intended outcomes or to create a structural outline of the benefits in order to comprehend the advantages of computer use.
5. Invite Bids: Following the completion of the aforementioned tasks, the concerned organizations should be notified to begin the computer procurement process, which involves determining specifications and including all relevant information. For example:
   • What benefits will there be?
   • Which language codes are written?
   • What is the name of the company?
   • His previous experience?
   • How is the price?
   • Whether there is UPS
   • Can it be changed?
   • Whether the code will work in the language in which it is written?
   • Tenders should be invited by considering the limitations of such aspects.

• Evaluation of Bids: A tender committee is required to evaluate the tenders as they are received after the invitation. The tender committee must have at least one computer expert. Alternatively, a comparative analysis should be prepared by an expert after the received tenders have been evaluated. Following the assessment, the best computer—that is, the business that stands to gain the most from the purchase of the computer—should be chosen. It should also be possible to get maintenance assistance and hardware updates, etc.
• Purchase and take delivery: Accepting the chosen computer requires issuing a work order. It is necessary to make plans to accept the work order from the tendering authority once it is published. It should be verified that the specification and the work order match at the time of acceptance
• Installation: It is important to make plans to accept the computer and assign it a designated location.

A systems analyst must ensure participation in the specified content activity.
